When Structural Roof Modifications Are Required for HVAC Replacement

Tue, 14 Apr 2026 18:12:08 GMT

When a rooftop unit is replaced with a similar unit of the same size and weight in the same location, structural modifications are often not required. The roof structure was originally designed to support the equipment load, and the existing curb and support structure can typically be reused.

Structural review or roof modifications may be required when:

The new unit is significantly heavier than the existing unit
The equipment footprint is larger or a different shape
Multiple smaller units are replaced with fewer larger units
Units are relocated to a different area of the roof
Ground-mounted equipment is being moved to the roof
Existing roof curbs need to be replaced or resized
The building is older and structural drawings are not available

In these situations, a structural engineer may need to review roof load capacity, joist spacing, decking condition, and equipment support locations to confirm that the building can support the new equipment layout.

Common Structural and Roof Modifications During HVAC Replacement

When structural modifications are required, the work typically involves reinforcing the roof structure or modifying roof openings to accommodate new equipment. Common modifications may include:

Reinforcing roof joists or roof decking
Installing structural steel supports
Adding equipment rails or platforms
Installing new roof curbs
Enlarging or modifying existing curb openings
Relocating rooftop units
Closing abandoned roof penetrations
Modifying duct penetrations through the roof
Adding service walkways around equipment
Installing vibration isolation supports

These types of modifications are not unusual in larger commercial HVAC replacement projects, especially when equipment layouts are being changed or buildings are being renovated.

Coordinating HVAC Replacement With Roof Replacement

In an ideal situation, HVAC replacement and roof replacement would be coordinated as part of the same capital project. Old rooftop units would be removed, the roof would be replaced, and new curbs would be installed before new HVAC equipment is set in place. This approach can reduce long-term costs and prevent future roof work from being complicated by newly installed equipment.

In reality, HVAC and roofing projects are often handled separately. Budgets may be managed by different departments, equipment replacement may be done in phases, and many buildings cannot operate without HVAC long enough to complete both projects at the same time.

When HVAC replacement and roof replacement cannot be completed together, some alternative project strategies can help reduce future complications:

Replacing units in phases instead of all at once
Installing new curbs during roof work even if equipment will be replaced later
Coordinating crane lifts for roofing and HVAC work when possible
Replacing roof sections around equipment
Planning roof and HVAC replacement within the same long-term capital plan

Planning these projects together, even if they are completed in phases, can help reduce future labor costs and avoid removing newer equipment to complete roof work later.

Rooftop Units on Sloped Roofs and Equipment Platforms

Rooftop units can still be installed on buildings with sloped roofs, but they typically require equipment platforms, rails, or structural framing to create a level surface for the equipment. These platforms must be properly supported and integrated with the roof structure and roofing system.

Because platform-mounted equipment changes how loads are distributed on the roof, structural review is often required for these types of installations. Access for service, safe walkways, and roof drainage must also be considered when equipment is installed on sloped roofs.

Coordinating Structural Modifications During HVAC Replacement

When structural modifications are required, the HVAC contractor typically coordinates with structural engineers, roofing contractors, electricians, crane companies, and other trades involved in the project.

Proper coordination between these trades helps prevent project delays, roof damage, and installation issues.

Commercial Rooftop Unit Replacement and HVAC Planning

Many rooftop HVAC replacements can be completed using existing curbs and roof supports, but structural modifications may be required when equipment size, weight, location, or roof conditions change. Planning ahead and coordinating HVAC replacement with roofing and structural work when possible can help reduce long-term costs and prevent future project complications.

Replacing Multiple Rooftop Units Over Several Years Instead of All at Once

Tue, 14 Apr 2026 18:09:49 GMT

Operational realities and capital planning considerations often lead property owners and management companies to replace rooftop units (RTUs) over several years instead of all at once.

Capital budgets are often spread over multiple years
Rooftop units fail at different times rather than all at once
Some units may be newer than others due to past replacements
Tenant spaces cannot all lose HVAC at the same time
Replacement work can be scheduled during milder weather
Roof sections may be replaced in phases
Many businesses cannot shut down for a full building HVAC replacement project

Why RTUs Can Usually Be Replaced One at a Time

In most commercial buildings, each rooftop unit serves a specific area rather than the entire building. A multi-tenant office building might have one unit per suite, while a warehouse or large open building might have several units that each handle part of the space.

Common RTU zoning layouts include:

One unit per tenant suite in multi-tenant buildings
One unit per floor in office buildings
One unit per building wing or section
Separate units for common areas such as lobbies or hallways
Multiple units serving a large open area such as a warehouse, gym, or church
Dedicated units for kitchens, server rooms, or other high-load areas

Replacing one rooftop unit usually only affects the area served by that unit, not the entire building. In a multi-tenant building, that might mean only one tenant loses cooling for a few hours while their unit is replaced.

In larger open buildings where multiple units share the load, the remaining units can often continue operating while one unit is being replaced.

To minimize disruption, rooftop unit replacement is often scheduled:

During milder weather when full cooling or heating is not required
After business hours or on weekends
During tenant vacancies or planned shutdown periods
With temporary cooling or heating equipment if necessary

How Phases Are Typically Prioritized

Most phased rooftop unit replacement projects prioritize individual units based on:

Equipment age
Repair history and maintenance costs
Units with higher failure risk
Units using obsolete refrigerant
Units serving critical areas such as server rooms or medical spaces
Units causing comfort complaints
Units with poor energy efficiency
Roof replacement schedules
Budget availability for each year

In addition to minimizing disruption (or at least limiting it to the fewest tenants possible at any given time), this approach allows capital costs to be spread across multiple budget cycles.

Challenges With Phased RTU Replacement

While phased replacement is often the least disruptive option for large-scale rooftop HVAC unit replacement projects, there are some challenges that facility managers should consider:

Different equipment ages and efficiencies across the building
Control system compatibility between old and new units
Multiple crane mobilizations over several years
Roof penetrations being modified multiple times
Parts becoming harder to find for older units
Maintenance complexity with mixed equipment ages

Planning phased replacement carefully and understanding the potential complications of the approach you choose can help reduce some of these issues.

When It Makes Sense to Replace All Units at Once

In some situations, replacing all rooftop units at the same time may make more sense than phased replacement. Full replacement may make sense when:

All rooftop units are the same age
A full roof replacement project is planned
The building is undergoing a major renovation
The building automation or control system is being replaced
Electrical upgrades are required for multiple units
Financing is available for a full replacement project
The building wants to standardize equipment across all units

If one or more of those factors apply to your project, completing all replacements at once may reduce long-term labor costs and avoid multiple crane mobilizations.

What Facility Managers Should Gather Before Requesting HVAC Replacement Bids

Tue, 14 Apr 2026 18:08:10 GMT

Before submitting a request for proposal (RFP) for an HVAC replacement project, facility managers and property managers can save time, reduce change orders, and receive more comparable bids by gathering the right information upfront. When contractors understand your building, equipment, and constraints, they can propose the right scope, plan realistic lead times, and flag potential cost drivers early. The checklist below outlines the details that most directly affect equipment selection, labor planning, crane needs, and electrical or controls coordination.

Basic Building Information

Contractors need a general understanding of the building before they can recommend equipment or provide accurate pricing. Coordinate with tenants, engineering staff, or maintenance teams to collect building details that influence load assumptions and zoning decisions.

Gather:

Building square footage
Number of floors
Building type (office, retail, warehouse, medical, restaurant, etc.)
Occupancy hours
Areas with higher heat loads (kitchens, conference rooms, server rooms)
Known comfort issues (hot spots or cold spots)

This information helps contractors provide recommendations on equipment sizing, zoning requirements, and whether the existing system design should be replicated or modified.

Existing HVAC Equipment Information

One of the most important steps before requesting bids is gathering information about the existing equipment. The more accurately you can identify what is currently installed, the easier it is for contractors to determine whether the replacement is truly like-for-like or if additional modifications should be assumed.

Gather:

Equipment model numbers
Serial numbers
Equipment sizes or tonnage
Approximate equipment age
Maintenance history (if available)
Known issues or recurring repair problems
Photos of equipment nameplates

Providing accurate equipment information allows contractors to determine whether a like-for-like replacement is the best approach or if additional modifications may be required.

Roof Information and Access

For buildings with rooftop units, roof conditions and access play a major role in replacement planning and cost. Even when the equipment selection is straightforward, roof access and crane planning can drive labor, scheduling, and safety requirements.

Gather:

Roof type (TPO, metal, modified bitumen, etc.)
Roof age
Planned roof replacement projects
Roof access type (ladder, roof hatch, elevator, stairs)
Clearance around existing units
Whether a crane will likely be required

Crane scheduling, roof access, and roof condition can significantly affect labor costs and project timelines, so this information is important early in the bidding process.

Electrical and Gas Information

Electrical infrastructure is one of the most common factors that affects HVAC replacement cost. If a contractor cannot confirm service size, available capacity, and disconnect locations, they may either exclude upgrades from the bid or add contingency to protect against unknowns.

Gather:

Electrical service size and voltage
Available panel capacity
Location of electrical disconnects
Known electrical capacity issues
Gas line sizes and meter capacity (for gas-fired equipment)

In some cases, electrical or gas upgrades may be required to support new equipment, which can add to the project cost and timeline.

Thermostats and Building Controls

Many commercial buildings use programmable thermostats, zoning systems, or building automation systems to control HVAC equipment. Controls compatibility can affect equipment selection and installation scope, especially in buildings with multiple zones or centralized control.

Gather:

Type of thermostats or control systems in the building
Whether the building uses a building automation system (BAS or BMS)
How many zones each unit serves
Control issues currently occurring
Whether controls will be upgraded during replacement

Project Timeline and Scheduling Requirements

Before requesting bids, consider project timing and scheduling constraints that impact labor planning, equipment delivery, and crane coordination. If after-hours work or phased replacement is expected, contractors should price and plan accordingly from the start.

Gather:

Desired project timeline
Busy seasons for the business
After-hours or weekend installation requirements
Tenant coordination requirements
Whether units will be replaced all at once or in phases

Providing this information helps contractors plan labor, equipment delivery, and crane scheduling.

Preparation Leads to More Accurate HVAC Replacement Bids

Accurate RFPs help, but there are factors outside a facility manager’s control that can influence pricing and project timelines—especially differences in how commercial HVAC contractors formulate bids. You could receive significantly different bids even if your RFP is entirely on point because contractors interpret scope differently or include different levels of work, overhead, and risk assumptions.

For example, one contractor may include new curb adapters, while another assumes existing curbs will be reused. One may include electrical upgrades, while another assumes existing power is adequate.

Why Commercial Buildings Experience Humidity Problems During Spring HVAC Transitions

Fri, 06 Mar 2026 20:38:09 GMT

Humidity complaints often arise in commercial buildings during spring, even when outdoor temperatures feel comfortable. Cooling demand is often low, outdoor air conditions fluctuate and systems may cycle more frequently than they do during peak summer operation.

These conditions can reduce a system’s ability to remove moisture from the air, allowing humidity levels to rise even when temperatures appear normal.

Low Cooling Loads Reduce Moisture Removal

Indoor moisture removal is largely a byproduct of the cooling process. When warm air passes over a cold cooling coil, moisture condenses on the coil surface.

During the spring months, compressors often satisfy temperature setpoints quickly and shut off after short cycles. A system that runs less often removes less moisture from the air.

This can leave indoor temperatures comfortable while humidity slowly rises, creating a damp or clammy feeling in occupied spaces.

Ventilation Air Can Introduce Additional Moisture

Most DFW commercial buildings are designed to bring in outside air for ventilation. While necessary for indoor air quality, ventilation air can also introduce moisture into the building.

Outdoor humidity can rise quickly in spring, even when temperatures remain moderate. During summer conditions when the cooling load is high, HVAC equipment is more effective at removing all that moisture before indoor conditions stabilize.

If cooling demand is low or the system cycles frequently, the equipment may not remove moisture as quickly as it enters the building.

Economizer Operation During Mild Weather

Many commercial rooftop units use economizers to bring in larger amounts of outside air when outdoor temperatures are suitable for cooling. Unsurprisingly, spring is the season when economizers most shine in Arlington and Fort Worth.

However, economizer controls in some systems rely primarily on temperature rather than humidity. If outdoor air is warm and humid but still within the temperature range for economizer operation, large amounts of moist air may enter the building.

Without sufficient cooling load to remove that moisture, indoor humidity can increase even while the system appears to be operating normally.

Airflow and Coil Performance Issues

Humidity removal also depends on proper airflow and cooling coil performance. If airflow across the coil is too high, the air may pass over the coil too quickly to remove significant moisture.

Excessive airflow or maintenance issues can lead to a noticeable reduction in coil performance. Dirty coils, incorrect refrigerant charge or airflow imbalances may limit the system’s ability to condense moisture effectively.

These problems often go unnoticed during winter when cooling systems are not operating regularly but may become obvious to building occupants during the spring transition.

Technologies and Strategies That Improve Humidity Control

Several strategies can help improve humidity control during seasonal transitions. Variable-speed drives on fans and pumps allow systems to operate longer at lower capacity, improving moisture removal during mild weather.

Modern building automation systems can also incorporate humidity sensors and improved control logic. This allows operators to better manage ventilation rates, economizer operation and equipment staging when humidity levels begin to rise.

In larger facilities, additional approaches such as reheat-based dehumidification or dedicated outdoor air systems can help separate ventilation and humidity control from space temperature control.

Why Spring HVAC Maintenance Helps Prevent Humidity Problems

Spring maintenance inspections can help identify many of the conditions that contribute to humidity problems. Checking coil condition, verifying airflow settings and confirming economizer operation can improve system performance before warmer weather arrives.

Technicians may also verify sensor calibration, inspect ventilation settings and identify mechanical issues that could affect humidity control.

Why Seasonal HVAC Control Changes Can Create Problems in Early Spring

Fri, 06 Mar 2026 20:34:15 GMT

Enabling economizers, adjusting heating lockouts and increasing outdoor air intake are normal and proper parts of early spring seasonal HVAC maintenance.

These adjustments are intended to prepare Fort Worth and Arlington buildings for the hot months on the horizon, and it’s typically better to have them too early than too late. But as every DFW resident knows, there are no guarantees when it comes to spring weather.

Sudden cold fronts or rapid temperature swings can create operational issues if systems are already configured for full cooling-season operation. That doesn’t mean alterations shouldn’t be made at the start of shoulder seasons, but controls should be thoughtfully adjusted to minimize instability and reduce the frequency of tenant comfort complaints.

Outdoor Air Settings Increased Too Early

Many commercial HVAC systems increase outside air intake as temperatures begin rising in early spring. Higher ventilation rates can improve indoor air quality and reduce the need for mechanical cooling when outdoor conditions are favorable.

However, outdoor air temperatures may still drop significantly during overnight hours and early mornings. If ventilation dampers are opened too aggressively, the system may introduce large amounts of cold air into the building.

This can force heating systems to run longer than expected or cause supply air temperatures to fluctuate as the system attempts to balance ventilation and heating demand.

Heating Lockouts Raised Too Soon

Commercial HVAC systems often use heating lockout settings that disable heating when outdoor temperatures rise above a certain point.

Problems can occur when lockout temperatures are raised too early in the season. If a late cold snap arrives, the system may no longer allow heating operation even though indoor spaces require it.

This situation can lead to uncomfortable indoor conditions until controls are adjusted again or outdoor temperatures rise.

Economizers Enabled Too Aggressively

Economizers allow rooftop units to use outdoor air for cooling when conditions are suitable. During mild weather, this can reduce compressor operation and improve energy efficiency.

However, economizers often rely primarily on temperature-based controls. If outdoor air is cool but still contains significant moisture, large volumes of outside air can enter the building.

During early spring the system may not run long enough to remove that moisture, particularly when cooling demand is low. This can lead to higher indoor humidity or unstable temperatures.

Reset Strategies Adjusted Too Early

Many commercial systems use reset strategies that adjust supply air temperature or system setpoints based on outdoor conditions. These strategies help improve efficiency during cooling season.

When reset schedules are adjusted too early, systems may begin operating as though summer conditions have already arrived. If temperatures drop suddenly, the system may struggle to maintain stable indoor conditions.

This can lead to frequent equipment cycling or inconsistent temperature control throughout the building.

Why Reviewing Spring Control Changes Matters

During a spring maintenance visit, commercial HVAC technicians typically check outdoor air damper operation, confirm heating lockout settings and verify that economizer and control functions respond properly to changing outdoor conditions.

These inspections are often when seasonal adjustments are made to prepare the system for cooling season. Understanding what settings were adjusted during service can help building managers stay informed about system operation and request changes if comfort issues develop.

An early spring inspection helps ensure the system is ready for the heavier cooling loads that are likely only weeks away. It can also reduce tenant complaints or performance issues that sometimes occur during unpredictable shoulder season weather.

Common Rooftop Unit Problems During Shoulder Seasons

Fri, 06 Mar 2026 20:30:28 GMT

Commercial rooftop HVAC systems are designed to handle the high heating and cooling loads of winter and summer in DFW, but shoulder seasons bring a separate set of challenges due to mild temperatures, rapid daily swings and lower overall demand.

During lower-demand months, rooftop units may cycle more frequently or struggle to maintain consistent temperatures throughout the day. Even seemingly minor performance issues in spring may point to control problems, airflow challenges or maintenance needs that should be addressed before peak cooling season arrives.

Low Load Operation and Compressor Cycling

During mild weather, rooftop units frequently operate well below their design capacity. Buildings may require only small amounts of cooling, especially during mornings or cloudy days.

When cooling loads are low, compressors may satisfy the thermostat quickly and shut off sooner than they would during hotter weather. This can result in more frequent cycling than normal.

While an RTU in good condition should be able to handle that operational cadence, repeated short run times can increase wear on compressors, contactors and other components.

Low load conditions may also expose oversizing problems in certain buildings. If the rooftop unit was originally sized for peak conditions but now serves a space with a reduced load, the system may struggle to operate efficiently during mild weather.

Heating and Cooling Changeover Conflicts

One of the most common shoulder-season issues is rapid switching between heating and cooling modes. A building may require heating during the morning when outdoor temperatures are cool and cooling by mid-afternoon once the sun warms the structure.

This daily shift can cause operational conflicts in some systems. Thermostats or building controls may call for cooling shortly after heating cycles have ended, leading to frequent mode changes throughout the day.

In larger buildings with multiple zones, some areas may still require heat while others begin calling for cooling. Without proper control sequencing, these competing demands can create comfort complaints and unnecessary equipment operation.

Sensor and Control Calibration Problems

Spring and fall conditions often reveal sensor or control calibration problems that remain unnoticed during steady heating or cooling seasons.

Temperature sensors that drift out of calibration can cause rooftop units to stage compressors improperly or run longer than necessary. Outdoor air sensors that read incorrectly may also trigger unnecessary cooling or prevent economizer operation when outdoor conditions are favorable.

Even small sensor errors can create inconsistent system behavior during mild weather when the difference between heating and cooling demand is relatively small.

Economizer and Outdoor Air Control Issues

Economizers tend to operate more frequently during shoulder seasons because outdoor air conditions are often suitable for cooling the building without running compressors.

When economizer components are not functioning correctly, several problems can occur. Dampers may fail to modulate properly, outdoor air sensors may report incorrect conditions or actuators may stick after long periods of limited use.

These faults can allow too much outdoor air into the building, causing temperature instability or forcing the mechanical cooling system to compensate.

Airflow and Maintenance Issues After Winter

Some rooftop units enter spring with maintenance issues that developed during the winter months. These problems may not become noticeable until the system begins running more regularly. Common examples include:

Loose or worn belts affecting airflow
Debris accumulation in outdoor coils
Condenser fan motors showing early signs of failure
Dirty filters restricting airflow

These issues can make rooftop units appear unstable during mild weather or reduce their ability to maintain consistent indoor conditions .

Why Shoulder Season Inspections Matter

Because rooftop systems experience a variety of operating conditions during spring and fall, these months are an ideal time to identify developing problems.

Routine maintenance during the shoulder season often includes checking sensor calibration, verifying compressor staging, inspecting airflow components and confirming that heating and cooling transitions occur correctly.

Mild outdoor conditions also offer an ideal opportunity to test economizer operation and diagnose mechanical or calibration issues.

Ensure Your RTUs Are Ready for Summer in Arlington and Fort Worth

Shoulder-season performance problems are often early indicators of issues that could affect reliability during peak cooling periods.

When HVAC Retrofits Deliver Better ROI Than Full System Replacement

Fri, 06 Mar 2026 20:25:44 GMT

There comes a point for every facility where declining HVAC performance and rising energy costs make full equipment replacement seem like an unavoidable expenditure. While that may be true for some HVAC equipment, it’s not always the case.

There are scenarios where rooftop units, air handlers and hydronic systems with years of usable life remaining can be retrofitted.

Targeted HVAC retrofits can improve efficiency and extend equipment life without the expense or disruption of replacing entire systems. Upgrades such as variable-speed drives, airflow improvements and modernized controls often deliver measurable performance gains while allowing facility managers to delay major capital projects.

Variable-Speed Drives and Fan Control Upgrades

One of the most common retrofit opportunities involves installing variable-frequency drives on HVAC motors. Many older systems run fans and pumps at constant speed even when full output is not needed.

Variable-speed drives allow motors to adjust their output based on building demand, like slowing down instead of operating at full capacity when airflow or pumping needs decrease. Because energy use drops significantly as motor speed decreases, these upgrades can reduce operating costs while improving temperature stability.

Variable-speed drives are commonly installed on supply fans in air handlers, condenser fans on rooftop units and pumps in hydronic heating or cooling systems.

Fan Arrays and Airflow Improvements

In larger commercial air handlers, older systems often rely on a single belt-driven fan. Over time these systems can develop airflow limitations or maintenance challenges.

Fan array retrofits replace large fans with several smaller direct-drive fans inside the same air handler. This design improves reliability, reduces belt maintenance and allows for more precise airflow control. Fan arrays also work well with variable-speed drives that adjust airflow based on building demand.

Pump Optimization in Hydronic Systems

Facilities with older chilled water or heating loops often operate pumps at constant speed. In many buildings, these pumps run at full output regardless of how much heating or cooling the building actually requires.

Adding variable-speed drives allows pump flow to adjust based on demand. This reduces electrical consumption while helping maintain more stable temperatures throughout the building.

Controls and Building Automation Improvements

Many older systems rely on outdated control strategies that limit efficiency and visibility.

Modern building automation systems allow operators to monitor equipment performance, improve scheduling and identify problems earlier. Updated controls can also improve staging and reduce unnecessary equipment cycling.

When Retrofits Make the Most Sense

Retrofits often provide strong returns when HVAC equipment still has several years of service life remaining but efficiency or control limitations are increasing operating costs. Buildings with structurally sound rooftop units or air handlers can often benefit from targeted upgrades that improve performance while delaying major capital replacement.

Some older systems may already include early versions of technologies such as variable-speed drives or basic automation controls. However, those earlier installations often lack the efficiency improvements, control flexibility and monitoring capabilities available in newer options.

When HVAC Replacement Is the Better Option

Unfortunately, retrofits are not always workable or the best solution. Equipment that is nearing the end of its service life, experiencing repeated mechanical failures or using outdated refrigerants may require full HVAC replacement .

Retrofit upgrades may also be limited by the design of older HVAC equipment. Certain motors, control boards or mechanical layouts may not support modern drives or control strategies without extensive modifications.

Evaluating the condition and configuration of your existing system will allow an HVAC installation professional to provide clear advice on whether modernization or full HVAC replacement is the better long-term investment.

How Aging Heat Exchangers Fail and What Warning Signs Often Get Missed

Tue, 17 Feb 2026 20:13:22 GMT

In commercial heating systems, heat exchanger failures rarely announce themselves with a dramatic shutdown. More often, problems develop slowly while equipment continues to run and spaces stay occupied. By the time a failure is obvious, risk and repair costs are already elevated.

Why Age and Operating Conditions Matter More Than Runtime

Heat exchangers fail from cumulative stress, not just hours of operation. Repeated heating and cooling cycles cause metal to expand and contract thousands of times over a system’s life. Morning warm-up sequences, short cycling and extended heating calls all contribute to fatigue.

In older commercial equipment, that stress is often compounded by deferred maintenance, changes in operating schedules or systems running outside their original design intent. Even when annual runtime seems modest, the mechanical strain adds up.

Signs of Trouble in Gas-Fired Furnaces and Rooftop Units

Combustion Indicators That Shift Over Time

Early warning signs often appear during combustion analysis. Readings may remain within acceptable limits, but trends start to drift. Slight increases in carbon monoxide, excess air changes or unstable flame characteristics can all indicate developing exchanger problems.

Hairline Cracking Patterns

Cracks in furnace heat exchangers often begin as fine fractures that open only when the metal is hot. During a cold inspection, the exchanger may appear intact. Under load, those cracks expand and allow combustion byproducts to escape into the airstream.

These failures commonly form near bends, welds and areas exposed to the highest temperature gradients.

Heat Stress Behavior During Operation

Operational symptoms can also point to exchanger degradation. Units may struggle during morning warm-up, trip high-limit controls intermittently or show declining heating efficiency without any obvious mechanical fault.

Each issue alone may appear to be minor, but together they indicate a system under thermal stress.

Boiler System Heat Exchanger Failure Profile

Boilers use heat exchangers to transfer combustion heat into water rather than air, so the failure modes and warning signs are different.

Gradual Efficiency Loss

As boilers age, scaling and fouling reduce heat transfer efficiency. The system compensates by running longer to meet demand. Fuel use increases even though comfort remains acceptable, which makes the problem easy to overlook until energy costs rise.

Material Fatigue and Corrosion

Older cast iron boilers are prone to sectional fatigue, while steel boilers are more vulnerable to corrosion. Leaks often begin as minor seepage at joints or sections rather than sudden rupture. These early-stage failures may not interrupt operation, but they may signal structural deterioration.

Combustion Clues That Get Missed

Changes in stack temperature, burner cycling patterns or excess air levels can point to exchanger degradation. Because boilers tend to be stable and forgiving, these signals are often attributed to normal aging rather than a developing failure.

High-Risk Conditions in Older Commercial Equipment

Certain conditions increase the likelihood of heat exchanger failure:

Equipment operating beyond its expected service life
Frequent warm-up cycles that stress metal components
Systems that have been repurposed without mechanical upgrades
Limited use of combustion analysis or performance trending

Buildings with multiple heating units are especially vulnerable. A single failing exchanger may affect only part of the building, allowing the problem to persist unnoticed.

Why Warning Signs Are Commonly Missed

Heat exchanger failures develop unevenly. Redundant equipment masks performance loss, and comfort complaints may be isolated or nonexistent.

Visual inspection alone rarely reveals early-stage cracking or internal corrosion. Without targeted testing, systems continue operating while risk increases.

When Heat Exchanger Issues Signal a Decision Point

At a certain point, continued operation with a compromised heat exchanger becomes a liability. Differentiating between manageable degradation and end-of-life risk requires combustion analysis, thermal evaluation and an understanding of how the equipment is actually operating.

Call Tom's Commercial at (817) 857-7400 for an evaluation and recommendation on furnace or boiler repair . Our HVAC technicians can identify heat exchanger problems early, allowing facility managers to plan repairs or replacements before safety concerns or unplanned outages force the issue.

Why Static Pressure Problems Become More Visible in Heating Season

Tue, 17 Feb 2026 20:08:54 GMT

Tenant complaints about cold spots, noisy airflow or slow warm-up often point to more than a heating capacity issue. In many commercial buildings, airflow issues stay hidden through summer and early fall, only becoming obvious once systems switch operating modes.

Heating season is shorter and generally less demanding than cooling in Arlington and Fort Worth, but it is far less forgiving of airflow and pressure imbalances.

Symptoms That Often Trace Back to Static Pressure

Heating-related complaints tied to static pressure usually show up in predictable ways:

Spaces that struggle to reach setpoint during morning warm-up
Uneven heating between zones on the same system
Supply air noise that appears only during heating calls
VAV boxes hunting or short cycling in mild winter conditions
BAS alarms related to airflow, fan speed or pressure rather than heat output

When these symptoms appear despite boilers, furnaces or heat exchangers operating normally, airflow resistance is often the underlying issue.

Why Heating Season Brings These Issues to the Surface

Heating mode changes how commercial HVAC systems move air. Those changes reduce tolerance for restrictions and control errors that cooling operation can mask.

Lower Airflow Exposes Restrictions

Most systems run lower airflow targets in heating than in cooling. When airflow drops, duct restrictions, dirty coils, undersized returns or poorly balanced zones consume a larger percentage of available static pressure. What passed unnoticed at higher cooling airflow suddenly limits delivery.

Fan Wear Shows Up at Reduced Speeds

Supply fans operating at lower RPM are less forgiving of mechanical issues. Worn belts, bearing degradation and wheel fouling can destabilize airflow when fans slow down. VFD-driven and ECM fans may hunt or fail to maintain pressure under these conditions, triggering comfort issues without obvious mechanical failure.

Return Air Problems Become Harder to Hide

In heating mode, reduced airflow leaves far less tolerance for return-side restrictions. Return paths that were marginal in cooling can create pressure imbalance once airflow drops, especially during morning warm-up. Interior offices and perimeter zones often show the first signs when return relief is undersized or poorly distributed.

Outside Air Damper Behavior Changes

During heating operation, outside air dampers typically remain at minimum positions for extended periods. Dampers that perform adequately during cooling modulation can struggle with accuracy at low positions, especially during morning warm-up. Even small positioning errors can disrupt return static pressure and destabilize airflow across the system.

Pressure Sensors and Control Logic Are Stressed

Static pressure sensors calibrated around cooling profiles may drift or misread conditions during heating. Control sequences also shift priorities between modes. Small inaccuracies that had little impact in summer can cause noticeable fan instability in winter.

Why Cooling Season Often Masks the Same Problems

Cooling operation provides more airflow and longer runtimes. Higher fan speeds overcome marginal restrictions, and continuous operation smooths out control instability. Comfort complaints during summer are often attributed to load or solar gain rather than airflow, allowing static pressure problems to persist unnoticed.

Heating season removes that margin.

Practical Solutions for Static Pressure Problems in Commercial Facilities

Verify Actual Static Pressure

Field measurements often reveal large gaps between design intent and real operation. Sensor accuracy and placement should be confirmed before adjusting setpoints.

Inspect Supply Fans and Drives

Belts, bearings, wheels and VFD response should be evaluated at heating speeds, not just cooling operation.

Assess Return Air Paths

Blocked or undersized returns are common contributors to static pressure imbalances. Door undercuts, transfer paths and return duct capacity all affect pressure balance.

Test Outside Air Dampers in Heating Mode

Observation in real operating conditions matters more than BAS commands. Actuator response and linkage condition should be verified.

Review Heating-Mode Control Sequences

Airflow logic and static pressure setpoints may need seasonal adjustment to match actual building behavior.

Consequences of Improper Economizer Setups in Commercial RTUs

Tue, 17 Feb 2026 20:04:17 GMT

Improper economizer operation is a recurring issue in rooftop units across light commercial buildings in Arlington and Fort Worth.

When working properly, economizers reduce cooling costs and support ventilation requirements. When they are misconfigured or poorly maintained, they can introduce comfort issues, indoor air quality complaints and unnecessary operating expense that can persist for years without drawing attention.

When Economizers Create Problems Instead of Savings

Most economizer problems do not cause immediate failures. Issues are easy to ignore when the system continues to run without obvious problems or tenant complaints. Over time, however, an improperly calibrated economizer can lead to sporadic IAQ complaints, humidity issues during mild weather or utility costs that do not align with outdoor conditions.

In many cases, the RTU will appear to heat or cool effectively but behave inconsistently depending on the time of year.

What Improper Economizer Setup Looks Like in Practice

Common setup issues include outside air dampers that do not match commanded positions, sensors that have drifted out of calibration or changeover logic that no longer reflects current DFW weather patterns.

Minimum outside air settings may also be altered during service or retrofit work and never be reset to the correct specifications. Individual issues may seem minor, but together they can significantly affect system performance.

Indoor Air Quality Issues

When economizer dampers fail closed or minimum outside air is set too low, ventilation will suffer. Occupants may notice lingering odors, stale air or increased CO₂ levels, particularly in higher-density spaces.

Because these conditions develop gradually, they are often attributed to occupancy changes or building age rather than a control issue at the rooftop unit.

IAQ complaints are frequently one of the first visible signs that economizer operation needs attention.

Humidity and Comfort Problems in North Texas

Humidity control is a common challenge in North Texas, and improper economizer operation can make it worse. During shoulder seasons, outdoor air may be cool enough to satisfy temperature demand but still carry significant moisture. If the economizer brings in that air when conditions are not truly favorable, the unit’s latent capacity can be overwhelmed.

The result is space conditions that meet temperature setpoints but feel clammy or uncomfortable. These issues are often misdiagnosed as cooling capacity or equipment problems when the root cause is outside air control.

Energy Use and Equipment Impact

Compressors may run unnecessarily when economizers fail to take advantage of suitable outdoor conditions. In other cases, increased cycling occurs as the system attempts to offset poor outside air control.

During heating season, excessive outside air can increase heating demand and contribute to simultaneous heating and cooling. Over time, this added runtime accelerates wear on compressors, fans and heating components, increasing maintenance costs without improving comfort.

Heating-Season Effects That Are Easy to Miss

Although economizers are often viewed as a cooling feature, their impact does not stop when cooling season ends. In mild winter conditions, improperly configured economizers can introduce more cold outside air than necessary. This increases heating load and can create drafts or uneven temperatures during morning warm-up.

Because heating season in North Texas is relatively short, these effects are often accepted as normal operation rather than recognized as a control issue .

Code and Compliance Considerations in Practice

Improper economizer operation can undermine required ventilation rates and energy performance goals, particularly during retrofits, recommissioning efforts or ownership transitions.

While property owners are unlikely to face immediate penalties for a misconfigured economizer, unresolved issues can surface during system evaluations, tenant improvements or broader energy assessments.

Why Economizer Problems Persist

Economizer issues often remain unresolved because systems continue to operate and comfort complaints may be inconsistent. Unlike compressors or burners, economizers receive less attention during routine service unless a problem is obvious. Since failures tend to appear only under specific outdoor conditions, long periods can pass without anyone noticing.

When Economizer Issues Require Professional Evaluation

Persistent IAQ complaints, unexplained humidity problems or energy use that does not track with seasonal conditions are strong indicators that economizer operation should be evaluated.

In many cases, correcting damper control, sensor accuracy or changeover logic can restore performance without major equipment changes .

That diagnostic focus is a key part of how Tom's Commercial approaches RTU service. Call us at (817) 857-7400 for an assessment of your RTUs’ economizers and eliminate the downstream problems that improper outside air control can create year-round.

What Causes Excessive Reheat Runtime in VAV Systems?

Tue, 17 Feb 2026 20:01:06 GMT

Facility managers in Arlington and Fort Worth may assume that constantly running reheat coils are normal during winter operation. They are not.

Excessive runtime may be a sign that something in the VAV system is working against itself, driving up winter utility bills, increasing tenant overheating complaints and generating trend data that reveals simultaneous heating and cooling.

Reheat is intended to fine-tune space temperature, not carry the bulk of the heating load. When it operates for long stretches or across large portions of a building, mechanical or configuration issues are usually driving the problem.

When Reheat Becomes a Cost Signal

Common reheat runtime warning signs tend to appear before anyone looks at the data:

Spaces may feel stuffy or overly warm even on mild days
Interior zones overheat while perimeter zones struggle to stabilize
Utility costs climb despite relatively short heating seasons

In many cases, the system is technically maintaining setpoint, but doing so inefficiently. These symptoms often point to airflow or valve problems rather than a lack of heating capacity.

Why Excessive Reheat Matters in Heating Season

During heating season, VAV systems operate with lower airflow targets and tighter control tolerances. That makes inefficiencies easier to spot in both comfort complaints and energy use.

Reheat coils that run excessively are compensating for another imbalance, and the longer that compensation continues, the more it costs in energy and equipment wear.

Damper Calibration Errors That Drive Reheat Demand

VAV box dampers that are out of calibration are a frequent cause of excessive reheat. The box may deliver more air than intended when a damper does not match its commanded position. That excess airflow cools the space, forcing the reheat coil to add heat just to maintain temperature.

Even small position errors multiplied across dozens of boxes can add up to significant runtime and energy waste.

Leaky or Passing Heating Valves

A valve that leaks hot water through the coil continues adding heat even when reheat is not called for. The system responds by adjusting airflow or cooling elsewhere, creating a loop of unnecessary heating and correction.

Passing valves are especially difficult to detect without inspection or trending. The space may appear comfortable, but the reheat coil is quietly running longer than it should, driving up winter utility costs and shortening valve and actuator life.

Minimum Airflow Settings That Are Too High

Improper minimum airflow settings are one of the most frequent contributors to excessive reheat runtime. Many VAV systems are configured with minimums based on cooling or ventilation assumptions that no longer match actual space use.

When minimum airflow is set too high, the box delivers more air than needed in heating season. Reheat is then forced to counteract that airflow just to maintain setpoint. This condition is especially costly in buildings with many interior zones, where heating loads are already low.

Adjusting minimums to reflect real heating needs can dramatically reduce reheat runtime without affecting comfort or ventilation.

Load Mismatch Between Cooling and Heating Design

VAV systems are fundamentally cooling-driven by design. In winter, those systems rely on reheat to correct a mismatch between how air is distributed and how spaces actually gain or lose heat.

Interior zones often require little to no heating, while perimeter zones fluctuate with outdoor conditions. When the system treats these areas similarly, reheat becomes the tool used to force balance. The result is prolonged operation that feels normal in practice but inefficient in reality.

Why These Issues Often Go Uncorrected

Excessive reheat is easy to overlook because it feels to occupants as if the system is working properly. Inefficiency is often tolerated as long as tenants aren’t reporting problems.

Without targeted diagnostics, reheat may be dismissed as a normal part of winter operation rather than a signal of mechanical or configuration problems.

Diagnosing Reheat Problems and Finding the Right Solution

Adjusting schedules or setpoints may not address the underlying issue causing excessive reheat runtime. Implementing the right solution that fixes the source of VAV problems can reduce winter energy spend and improve overall system stability across every season.

Why Commercial Boilers Lose Efficiency Midseason Even After a Fall Tune Up

Wed, 21 Jan 2026 19:23:52 GMT

It’s a common frustration for facility managers and building operators. The boiler passes its fall tune‑up , startup looks clean and early heating season performance seems fine. Then, halfway through winter, fuel usage creeps up, recovery times slow and comfort complaints start rolling in.

At that point, it’s tempting to assume the boiler itself is failing. The good news is that, in many of these mid-winter performance drop-off scenarios, it’s more about real-world operating conditions than the boiler itself.

What a Fall Tune‑Up Does and Doesn’t Address

A fall boiler tune‑up typically focuses on combustion checks, safety controls, startup operation and visible maintenance items. Those steps are essential, but they’re largely static snapshots of boiler performance.

A fall tune-up won’t always reveal issues that develop once the boiler is running longer hours, cycling more frequently or interacting with other system components under real mid-winter demand conditions. It’s not uncommon for inefficiencies to emerge only after weeks of high-demand operation.

Water Quality Issues That Show Up Under Load

Water quality is one of the most common contributors to declining boiler efficiency as winter progresses. Scale buildup, corrosion products and sludge reduce heat transfer efficiency and restrict flow through the heat exchanger. Even modest deposits can force the boiler to burn more fuel to deliver the same amount of heat. These issues may not be obvious during startup but become increasingly problematic as runtime increases and water temperatures remain elevated for longer stretches.

Part‑Load Operation and Short Cycling

Most commercial boilers are sized for design conditions that occur only during the coldest days of the year. For much of the season, the boiler operates at part load. If staging, modulation or turndown aren’t well matched to actual demand, efficiency can drop, short cycling can become more frequent and the system may struggle to reach steady‑state operation.

Over time, this increases fuel consumption and accelerates wear on burners, controls and ignition components.

Pump Curves and Flow Mismatches

Boilers depend on proper water flow to maintain efficiency and protect internal components. As zones open and close throughout winter, actual system flow often deviates from design assumptions. Pumps that are oversized, undersized or mismatched to the current load can reduce delta‑T across the boiler, limiting heat transfer and increasing runtime.

These issues rarely surface during fall startup but become more pronounced midseason when multiple zones demand heat simultaneously.

Controls and Sensor Accuracy Matter More Than Expected

Commercial boilers rely heavily on accurate temperature and flow sensing to regulate firing rates and staging. Sensor drift, failed probes or poorly placed sensors can quietly degrade performance. If the boiler is operating based on incorrect data, it may fire longer than necessary or fail to respond properly to load changes.

Control logic that hasn’t been reviewed since installation can also contribute to inefficiencies once operating conditions shift deeper into winter.

Signs Your Boiler Is Losing Efficiency

Midseason efficiency loss often shows up as longer warm‑up times, uneven heating across the building, rising fuel bills or increased cycling. In some cases, operators notice new noises, higher stack temperatures or boiler lockouts that weren’t present earlier in the season.

These symptoms point to system‑level issues rather than isolated equipment failure.

Why Midseason Diagnostics Matter for Boiler Performance in Arlington and Fort Worth

Waiting until a boiler fails outright is rarely the most cost‑effective approach. Midseason performance checks allow technicians to evaluate water quality, verify flow rates, review control behavior and identify inefficiencies before they turn into major repairs. Addressing these issues early can stabilize performance, reduce operating costs and extend equipment life.

The Operational Costs of Ignoring Air Leakage in Multistory Commercial Buildings During Cold Spells

Mon, 19 Jan 2026 19:19:52 GMT

Air leakage in multistory commercial buildings isn’t limited to drafty entryways or aging window frames. During cold spells, warm air escaping through upper floors, shafts and roof penetrations can create pressure imbalances that pull cold air deep into the building, even in interior spaces with no operable windows or exterior doors. These leaks show up as uneven heating, persistent drafts and systems that struggle to keep up despite adequate equipment and routine maintenance.

The Stack Effect and Pressure Imbalances

Stack effect is a powerful force in tall buildings during cold weather. Warm indoor air rises and escapes through roof hatches, elevator shafts or upper-floor leaks, creating negative pressure that draws cold outside air in at lower levels.

This constant movement of air pushes your heating system to work harder, often running longer hours just to maintain setpoints. As a result, floors near the top can overheat while ground-level zones remain uncomfortably chilly.

Common Sources of Air Leakage in Commercial Structures

Unsealed Doorways: Exterior doors without proper weatherstripping are a major entry point for cold air, especially if automatic closers aren’t working or doors are propped open for deliveries.
Loading Docks and Access Bays: Dock doors and freight access points that don’t close fully create constant air leaks. In busy buildings, these areas may be open for long periods, compounding the loss.
Utility and Pipe Penetrations: Openings for electrical, plumbing or IT lines often run through walls, ceilings and mechanical rooms. If not sealed tightly, they can act as small chimneys for air leakage.
Elevator Shafts and Stairwells: These vertical shafts can act as highways for stack effect, drawing warm air up and out while pulling cold air into lower floors, especially when doors don’t seal tightly.
Roof Hatches and Mechanical Penthouse Access: Poorly sealed roof hatches or penthouse access points are frequent trouble spots in multistory buildings. Warm air naturally rises and can escape quickly through these openings.
Window Frames and Curtain Wall Gaps: Older buildings or those with aging window systems often have leaky frames, failing gaskets or loose panels. Even small cracks can allow significant heat loss during a cold spell.
After-Hours Modifications: Temporary cables, event access doors or construction cutouts made for short-term needs often get overlooked during regular maintenance, leaving unsealed gaps.

Real-World Impact on Heating Loads and Utility Costs

A half-inch gap under a door is equivalent to a fist-sized hole in the wall in terms of air leakage. During cold snaps, these losses are magnified. In severe cases, a facility’s HVAC system may run non-stop, increasing both energy bills and wear on key components.

Persistent air leakage can also lead to short cycling, temperature swings between floors and more dissatisfied occupants and tenants.

Diagnosing and Quantifying the Problem

Finding air leaks in multistory commercial buildings usually takes more than a walk-through. Professional diagnostics often include thermal imaging to spot cold spots along exterior walls, rooflines or around penetrations.

Building pressure measurements with handheld manometers at doors, stairwells and shafts can help identify zones under negative or positive pressure.

Facility teams can identify places with unexplained drafts, persistent cold spots and wide temperature swings between floors ahead of time to narrow down where problems are located.

Building Sealing and Balancing, Along With Consistent Maintenance, Help Prevent Common Winter Heating Challenges

The most effective approach to preventing air leaks is to prioritize sealing the largest and most accessible leaks first. Exterior doors, roof penetrations and mechanical shafts often yield the biggest returns .

Coordinating these sealing efforts with HVAC system balancing and controls adjustments helps ensure that air isn’t being pushed through new “weak spots” after the initial fixes.

Regular reviews and inspections , especially after any remodel or major equipment change, are essential for keeping the building envelope tight and energy bills under control.

If you’re concerned about air leakage or escalating heating costs in your commercial building, Tom’s Commercial offers comprehensive diagnostics and sealing services to keep your systems running efficiently, even during the harshest North Texas winters.

What Facility Teams Miss When Evaluating Heating Complaints in Mixed-Use Buildings

Fri, 16 Jan 2026 19:15:39 GMT

Dependable HVAC performance in Arlington and Fort Worth is likely second only to dependable internet service in the hierarchy of tenant requirements. Having to lodge the same heating complaints repeatedly in mixed-use buildings can fray the nerves of even the most patient, low-maintenance tenants.

Unfortunately, the fix to persistent heating complaints is almost never as simple as replacing a broken thermostat or a dirty filter.

Zoning and Configuration Mismatches

One of the most common problems in mixed-use properties is that HVAC zoning and physical space layouts don’t match up, often due to tenant turnover, remodels or changes in how areas are used. A system designed for an open office may now serve separate suites, or a retail floor may have been carved into multiple spaces.

When zoning boundaries don’t match ductwork and control strategies, some areas never reach setpoint while others overheat.

Airflow Obstructions and Damper Issues

Blocked airflow is almost always a matter of physical obstructions or damper malfunctions:

Furniture, shelving, equipment or displays placed directly in front of supply or return vents can choke off airflow to entire zones.
Broken, manually closed or misadjusted dampers, especially after a remodel or tenant buildout, often go unnoticed until complaints roll in from the new tenant.
In some cases, ductwork is modified or disconnected during space changes and never properly balanced again, throwing off comfort for months or even years.

VAV Box and Control Faults

Buildings equipped with variable air volume (VAV) boxes or advanced control systems bring another set of potential headaches. Stuck or drifting dampers, failed actuators or unresponsive reheat coils in VAV boxes can create room-by-room temperature swings that simple thermostat adjustments won’t solve.

Sensor placement is also critical. Sensors in dead zones, in the path of direct sunlight from windows or near heat-producing equipment can fool the system into running when it shouldn’t, or shutting off too soon.

Overlooked schedule overrides or “temporary” BMS changes can also lock systems into inefficient modes, especially after an event or maintenance visit.

Occupant Density and Behavioral Shifts

Unlike single-use buildings, mixed-use properties can experience significant variations in occupancy. Systems tuned for average use can’t keep up when space use spikes, and set-it-and-forget-it schedules miss the mark. Heating complaints often increase not because the system is broken, but because it’s not adapting to real-world use.

Overlooking Pressure Imbalances and Building Envelope Issues

Facility teams often focus on equipment and zoning, but building pressure imbalances and envelope leaks can be a silent source of persistent heating complaints.

If exterior doors don’t close fully, vestibules are poorly sealed or stairwells act as unintended chimneys, conditioned air can escape while cold drafts seep in.

Stack effect and unsealed penetrations, especially in multistory buildings, can make some spaces impossible to keep comfortable, regardless of thermostat or VAV settings. Without periodic envelope assessments or pressure checks, teams may chase HVAC adjustments that never solve the underlying problem.

Why Winter Puts These Issues in the Spotlight

Many comfort problems in mixed-use buildings lurk beneath the surface during mild weather, only to become obvious as colder temperatures set in.

During mid-winter, systems work harder and for longer hours, amplifying the effects of misaligned zoning, blocked airflow or control issues that might have been manageable in fall or early winter.

The extra demand exposes any weaknesses in system balance or responsiveness, leading to a surge in complaints. That’s why it’s often not until winter’s peak, when facility management teams are inundated with tenant complaints, that they realize an underlying problem needs a targeted solution.

Accurately Diagnosing the Cause of Heating Problems and Providing Effective, Long-Term Solutions

Solving heating complaints in mixed-use buildings means thinking beyond the basics. That includes holistic airflow measurement, confirming zoning matches real-world use, reviewing control sequences and sensor locations and mapping how occupant behavior changes throughout the day.

Periodic reviews, especially after tenant or layout changes, are key to keeping complaints from piling up each winter.

How Control Sequence Drift Causes Heating Systems to Underperform During Peak Winter Demand

Wed, 14 Jan 2026 19:10:38 GMT

The heating systems in many Arlington and Fort Worth commercial buildings often keep up just fine during cool fall mornings. But then a true North Texas cold snap hits and suddenly some zones are struggling to reach setpoint or are running flat out with little improvement.

If filter changes, setpoint tweaks and basic service don’t get a system back to normal, the problem may be deeper. One of the most frequently overlooked causes is control sequence drift, a multifaceted phenomenon that can be tough for even an experienced facility management team to diagnose on their own.

What Is Control Sequence Drift?

Modern commercial heating systems rely on programmed sequences to coordinate stages, manage economizers and respond to changing demand.

Whether your facility has packaged rooftop units or a full BMS-integrated plant, each component is supposed to act in sync, ramping up or down in response to actual load and outside conditions.

Sequence drift happens when the system’s actual behavior starts to diverge, sometimes subtly, sometimes dramatically, from its intended logic.

How Sequence Drift Develops in Commercial Buildings

Several factors can push a control system out of alignment over time:

Seasonal overrides and forgotten setpoints: Quick fixes for a one-off comfort complaint are often left in place, gradually stacking up as new staff or techs make adjustments without resetting to baseline.
Sensor drift: Even high-quality temperature, pressure or airflow sensors can lose calibration over months or years. The system may be “reading” an outdoor temp that’s several degrees off or staging based on a faulty signal.
Software updates and resets: Routine updates or power cycles can reset certain defaults, quietly undoing previous optimization or introducing small mismatches.
Multiple hands on the system: Different vendors, contractors or operators may make uncoordinated changes, resulting in conflicting logic or setpoints.

The Hidden Consequences During Peak Demand

In mild weather, sequence drift is easy to miss. But as load rises and margins tighten, it can lead to:

Misaligned staging: Heating stages activate out of order or not at all, leaving capacity unused when you need it most.
Economizer interference: A misprogrammed or drifting economizer can pull in more outdoor air than intended, forcing the system to reheat cold outside air instead of recirculating warm return air.
Zone imbalance and comfort complaints: Some areas may overheat while others never catch up, leading to calls from tenants or facility staff.
Short cycling or excessive runtime: Systems that can’t satisfy demand may run longer, cycle more often or rack up utility bills and wear.

Why Cold Snaps Make the Problem Worse

On mild days, your heating plant has room to absorb small errors in sequence or staging. But when a true cold snap hits, the difference between a perfectly coordinated system and one with sequence drift can mean the difference between stable comfort and widespread complaints.

Drifting logic doesn’t have the capacity to catch up or recover quickly. Issues that were only “mild annoyances” last month may become urgent failures when outside temperatures plunge.

Diagnosing and Correcting Sequence Drift

Identifying sequence drift isn’t always straightforward. Being able to accurately analyze trend logs, system data and BMS reports is critical. Facility managers or commercial HVAC technicians can use that data to identify unexpected staging, inconsistent temperature readings or economizer dampers opening at the wrong time.

Calibrating sensors, reviewing setpoints and testing control sequences under load can help pinpoint where the drift has crept in.

Preventing Future Sequence Drift Issues in Commercial Facilities in Arlington and Fort Worth

The best way to avoid sequence drift headaches is with periodic review and calibration. An annual sequence check as part of your winter startup can catch small misalignments before they become major issues.

Make sure sensor calibrations are scheduled, and that access to controls and programming is clearly documented to avoid conflicting changes by different techs or operators.

The Hidden Cost of Oversized Commercial HVAC Units in Modern Low-Load Environments

Thu, 18 Dec 2025 19:59:14 GMT

Envelope upgrades, LED retrofits, tighter construction practices and lower plug loads all reduce the amount of conditioning a space needs. Yet HVAC equipment is often replaced at the same tonnage it had decades ago when the building’s first system was installed. Oversizing becomes the default when installers don’t accurately recalculate the load after improvements have been implemented.

Efficiency, comfort and reliability all decline when a unit doesn’t match the building’s real load profile. Bigger equipment delivers less useful conditioning and creates operating conditions the original design never accounted for.

Short Cycling Shows Up First

Oversized units satisfy space temperature quickly and shut off before the system has reached stable operation. Instead of long, efficient cooling cycles, the compressor switches on and off repeatedly. That cycling creates two major costs: reduced efficiency and increased mechanical wear.

Systems that run only in short bursts never reach steady-state coil performance, which is where the unit operates most efficiently. Compressors and blowers shoulder more starts, which accelerates fatigue and elevates electrical stress.

Buildings that have undergone insulation upgrades or lighting retrofits see this happen frequently because their peak loads drop far below the equipment’s capacity.

Humidity Issues Become More Noticeable

Short cycling also cuts dehumidification time. Coils must remain cold for a sustained period to remove moisture effectively. In a low-load building, an oversized unit reaches its thermostat setpoint before meaningful moisture removal occurs. Supply air temperatures bounce, and the space can feel cool but damp.

Facilities with intermittent occupancy are especially vulnerable. Classrooms, meeting rooms and small offices experience rapid swings between empty and full, and oversized equipment rarely adapts well to that pattern. In a climate with strong latent load periods, humidity performance is a real operational concern.

Higher Operating Costs Despite Higher Capacity

Oversizing delivers more tonnage but less usable efficiency. Several energy penalties show up in the field:

Fan energy remains high because the blower runs at full speed each cycle
Cycling losses reduce effective SEER or IEER
Economizers and ventilation controls struggle because they expect steady operating conditions

A unit with excessive load capacity cannot deliver the expected savings, regardless of its nameplate rating.

More Wear on Components and Reduced Service Life

Mechanical stress increases when components never settle into consistent operation. Contactors close more often, relays activate repeatedly and compressors face high starting torque conditions far more frequently. Coils that never operate under stable airflow lose efficiency and run at higher discharge temperatures.

These problems create long-term maintenance costs that look unrelated at first: nuisance breaker trips, intermittent comfort complaints, inconsistent supply temperatures. Oversizing is often the hidden connection.

Why Oversizing Persists in Replacement Projects

Contractors don’t intentionally install oversized replacement units. They appear because the existing tonnage becomes the default choice. While not a universal phenomenon, some installers fail to adjust for all tenant improvements that have reduced internal load over the years or decades.

Envelope sealing and reflective roofing lower peak cooling demand. Occupancy patterns change. Yet when a unit reaches the end of its life, its replacement is often ordered at the same size without the necessary review to ascertain how much the load has changed since the old system was installed.

Right-Sizing Through Updated Load Calculations

An updated load calculation provides a current picture of how the building actually behaves. This involves reviewing envelope improvements, evaluating infiltration and ventilation needs and understanding the modern equipment profile within the space.

It also gives facility managers and owners the opportunity to select equipment with staging or modulation that better matches current day-to-day operating conditions.

The goal should always be to align the unit with the building’s true load so that the equipment can run long enough to control temperature, humidity and airflow consistently.

Maintain Better Building Performance in DFW By Matching Capacity With Demand

Spaces that have suffered from bounce, humidity drift or inconsistent supply temperatures after changing use patterns or efficiency upgrades often stabilize once the equipment matches the current load.

Cycling decreases, economizers operate more effectively and indoor comfort improves with fewer mechanical stresses. Buildings with wide occupancy swings benefit the most because properly sized equipment handles part-load conditions more predictably.

If you're developing a replacement plan or reviewing equipment that no longer matches your building’s load, coordinate a sizing review with Tom’s Commercial by calling 817-857-7400. We can evaluate your current envelope conditions and provide recommendations that align capacity with real-world performance.

How Refrigerant Circuit Contamination Impacts Commercial System Reliability

Wed, 17 Dec 2025 21:02:42 GMT

Refrigerant contamination is one of the most damaging conditions in commercial DX systems , especially in buildings with equipment that has been serviced repeatedly over many years. Moisture, acid and particulate matter undermine metering performance, weaken lubrication and shorten compressor life.

These issues often show up in DFW properties with aging equipment that has undergone repeated leak repairs. Each repair is another chance that contaminants enter the circuit.

How Contamination Gets Into Commercial Systems

Lines left open to the atmosphere during service work pull in moisture, and inadequate evacuation leaves vapor trapped in the piping. Air intrusion is common during leak repairs on older equipment, especially when work occurs in tight chases or rooftop conditions with wind and debris. Improper brazing creates copper oxide that flakes off and travels through the system.

A second group of contaminants forms internally, such as when a compressor burnout distributes acid through the oil and refrigerant. Unless the circuit is fully cleaned, that acid continues attacking metal surfaces long after the new compressor is installed.

Older systems also accumulate debris from past repairs, failed filter driers or coil replacements, which easily migrates toward metering components.

How Contamination Disrupts TXVs and Metering Performance

TXVs react quickly to contaminants. Particulates settle at the orifice and restrict flow, creating unstable superheat that affects the entire system. Wax from overheated POE oil binds internal surfaces and slows pin movement, and acid scoring reduces the valve’s ability to modulate during load changes. These conditions mimic symptoms of low charge or inadequate airflow, which is why intermittent performance problems in older RTUs often trace back to contamination rather than refrigerant quantity.

Why Compressor Oil Quality Declines in Contaminated Circuits

POE oil absorbs moisture readily, and once water enters the system it triggers chemical changes that weaken the oil’s lubricating properties. As contamination increases, oil becomes more acidic and less effective at protecting bearings and scroll sets.

Miscibility problems also appear: degraded oil may not return properly from long evaporator circuits or extended line sets. Facilities with long piping runs are particularly susceptible, as any drop in oil quality magnifies the challenge of maintaining consistent lubrication.

Signs of declining oil quality include higher compressor amp draw, elevated discharge temperatures and early winding fatigue. These indicators show up even when refrigerant charge and airflow appear normal.

Compressor Failures Driven by Contamination

A contaminated circuit can destroy multiple compressors if the underlying problem is not addressed. After a burnout, acid remains inside the system without proper flushing, drier replacement and deep dehydration. The new compressor inherits the same environment and often fails in a similar pattern.

Signs that continued contamination is responsible for compressor failures include:

Repeat burnouts
Bearing washout and increased mechanical noise
Restriction at the metering device leading to high head pressure
Discharge temperature spikes during peak-load operation

When these symptoms appear together, the refrigerant circuit is usually the root cause.

Components Beyond the Compressor That Suffer Damage

Contamination affects many components, not just metering devices and compressors:

Reversing valves can stick when copper plating forms inside the pilot passages
Solenoids and check valves fail when debris settles in critical openings
Coils exposed to acidic refrigerant corrode internally, reducing heat-transfer efficiency long before leaks appear

Identifying Contamination in the Field

Technicians rely on more than pressure readings to confirm contamination:

Oil samples reveal moisture levels, acid presence and early signs of metal wear
Moisture indicators at the liquid line help show whether the system has dehydrated properly
Superheat patterns, valve response and temperature splits across coils are tracked during varying load conditions to identify restrictions

How Contaminated Systems Are Restored

Corrective work depends on severity. Typical steps include:

Extended evacuation to remove moisture
Installing oversized filter driers and replacing them after cleanup
Flushing or replacing line sets when particulate load is high
Replacing TXVs or coils that remain restricted after dehydration

Tom’s Commercial focuses on restoring reliability without unnecessary component replacement. Call 817-857-7400 to schedule a field evaluation to confirm whether moisture, acid or particulate contamination is driving your system issues.

Why Many VFD Retrofits Underperform Without a Controls Recalibration Plan

Wed, 17 Dec 2025 20:55:56 GMT

Variable-frequency drives can stabilize airflow, reduce fan energy use and smooth out system operation, but many retrofits fall short of expectations because the supporting controls never get updated.

The drive is installed, the fan modulates and the rest of the system continues behaving as if it still has a constant-speed blower. When controls remain calibrated for fixed airflow, efficiency, comfort and reliability all suffer.

Where VFD Retrofits Typically Fall Short

Most underperforming VFD projects share the same root cause: the original sequences were never rewritten for variable airflow.

Systems that once relied on full-speed operation now require updated logic for pressure, airflow and equipment staging. Without that recalibration, the drive ends up reacting to control signals that were never designed to modulate.

Common mismatches include static pressure targets set for constant-speed blowers and airflow assumptions baked into economizer logic. Morning warm-up cycles and purge routines can become unstable because their timing and temperature targets were tuned for maximum airflow rather than variable operation.

Legacy Logic Working Against New Drive Behavior

Older AHUs, RTUs and makeup air units were designed around predictable airflow. When a drive modulates, the rest of the system may misinterpret normal fan turndown as a fault condition.

Unchanged control sequences often lead to rapid modulation, short cycling at low demand and airflow-related nuisance alarms.

Problems usually trace back to logic written for equipment that only had two positions: on and off. Drives introduce a continuous range between those points, and without updated sequencing, the controls fight the modulation rather than working with it.

Sensor Placement and Calibration Problems

A VFD depends on accurate data. Once airflow becomes variable, sensors that worked adequately at a constant speed can produce unstable readings. Poor sensor placement around elbows, transitions or turbulent airflow creates noise that drives erratic fan behavior. Field issues often involve:

Static pressure sensors mounted too close to supply fans
Return sensors drifting after years of operation
Temperature sensors positioned where turndown creates short-circuiting or stratification

When inputs are unreliable, the drive hunts, overshoots and fails to maintain stable pressure or airflow.

Mechanical Realities That Controls Must Reflect

A recalibration plan has to address mechanical constraints, not just programming. Many systems have airflow characteristics that limit how far a VFD can turn down without compromising performance. Key mechanical boundaries include:

Duct systems that develop unstable pressure at low speeds
Return limitations that prevent adequate airflow during turndown
Equipment that loses coil performance below a minimum CFM
Supply air temperature swings that appear when modulation exceeds the unit’s range

A successful integration plan calibrates the drive to operate within what the ductwork, coil and fan assembly can reliably support.

Common Signs a Retrofit Lacks Controls Integration

Underperforming VFD projects tend to show the same symptoms across midsize commercial buildings:

Fan speed never dropping to designed minimum airflow
Duct pressure oscillating around setpoint
Economizers failing to reach full open due to outdated airflow assumptions
Low-airflow safeties tripping despite adequate capacity
Higher energy use than expected because the drive is fighting fixed sequences

These issues often persist until the control logic is rewritten to match the drive’s capabilities.

What a Controls Recalibration Plan Should Include

A complete plan goes beyond the drive installation and addresses how the system will operate in real conditions. Essential steps include:

1. Redefining minimum and maximum airflow for equipment protection and comfort

2. Updating static pressure control loops to support modulation

3. Recalibrating or relocating sensors to deliver stable readings

4. Revising economizer sequences, warm-up routines and purge cycles

5. Validating performance at multiple fan speeds and load conditions

Commissioning That Protects the ROI of a VFD Retrofit Project

Commissioning after a VFD retrofit ensures the system performs as intended rather than as assumed. This includes functional tests for each operating mode, documenting acceptable pressure and temperature ranges and confirming that staging and economizer strategies behave consistently at modulating airflow.

Trending helps verify long-term stability so facilities teams know what normal operation should look like.

Why System-Level Integration Matters for Facilities in Arlington and Fort Worth

Without recalibrated controls, the expected gains from a VFD retrofit rarely materialize. If a recent VFD retrofit isn’t delivering expected savings, coordinate a controls assessment with Tom’s Commercial by calling 817-857-7400. Or bring our DFW commercial HVAC experts into the evaluation phase to verify system compatibility before retrofitting.

How Poor Duct Design Drives Up Static Pressure in Large Commercial Systems

Wed, 17 Dec 2025 20:50:34 GMT

Static pressure issues reduce airflow, cut capacity and force equipment to operate outside its intended range. Blowers draw more amperage, compressors run hotter and the entire system becomes more sensitive to peak-load conditions.

Duct design choices are often to blame for these problems, and there are specific scenarios in which they are particularly common.

Undersized Trunks and Excessive Friction Loss

A large share of high pressure readings start with undersized supply trunks. When the duct cannot move the volume of air the equipment is designed for, friction increases, velocity rises and total external static pressure climbs above the unit’s rating. Once that happens, blower motors operate at higher load, belts fail more often and cooling capacity drops noticeably on hotter days.

This is common in buildings that have expanded over time without updating the main distribution network. For example, churches may have this problem after adding classrooms or offices around the original sanctuary. The primary trunks were sized decades ago for a different layout, and the extra connected load forces the system to push air farther than intended.

Older two-story office buildings show similar patterns when tenants reconfigure open areas into partitioned spaces.

Return-Side Restrictions That Starve Equipment of Air

When return paths are undersized, routed through long horizontal runs or partially obstructed, the equipment struggles to pull the volume it needs across the coil, which:

Raises pressure on the return side
Increases blower strain
Reduces evaporator performance
Creates temperature swings that facility staff often misinterpret as thermostat or control problems

Return-side restrictions are common in large facilities built in the 1960s through the 1980s, like older school buildings. Renovations over the years add new drops and extend return ducting through crowded plenum spaces that were never intended to carry that much airflow.

Warehouses with mezzanines or large storage racks run into another version of the same problem: the return opening becomes unintentionally blocked, sending ESP upward and forcing RTUs to run harder than necessary.

Improper Use of Flex Duct During Renovations

Flex duct has legitimate uses, but misapplication is one of the fastest ways to drive up static pressure:

Long flex runs sag, reducing effective diameter
Sharp bends add turbulence
Poorly cut takeoffs constrict airflow right at the start

Because flex is a common material in quick-turn renovations, these problems show up frequently in office interiors, tenant improvements and repurposed commercial suites.

A typical pattern is a remodel where hard pipe was removed to speed up construction and replaced with long flex runs feeding multiple diffusers. Once installed, the airflow imbalance becomes obvious. One area receives adequate cooling while zones farther down the same run see diminished airflow.

Meanwhile the blower is working significantly harder to overcome the pressure created by the added resistance.

Unbalanced Duct Networks After Additions or Partial Retrofits

Duct network can become a patchwork of differing friction characteristics when a building is expanded, renovated or selectively upgraded. Branches added years after the original installation often tie in at points that already operate near their allowable pressure.

Even when the airflow of a single branch seems minor, these additions accumulate. The result is a system that performs adequately in mild weather but loses control under peak load because the duct layout no longer matches the equipment’s intended operating range.

The imbalance makes some spaces noisy, others undercooled and all of them harder on the equipment than necessary.

Compounding Mechanical Stress When Static Pressure Remains High

Once static pressure rises beyond design, mechanical consequences occur quickly:

Blower motors and belts live shorter lives
Compressors cycle more frequently, operate hotter and rely on higher amp draw
Coils see reduced heat transfer because airflow across the surface drops
Controls and safeties trigger more often, creating nuisance shutdowns that facility teams may attribute to electrical or refrigerant issues when airflow is the underlying cause

By the time a unit begins tripping on high head pressure during summer, the duct system has typically been operating above allowable static pressure for years.

Corrective Strategies That Bring Commercial HVAC Systems Back Within Range

Fixing high static pressure rarely requires a full redesign. Most buildings benefit from targeted corrections that focus on the most restrictive points in the system:

Increasing return capacity often delivers the largest improvement
Replacing long runs of flex with hard pipe, resizing critical ducts or reworking takeoff placement reduces turbulence and brings external static pressure back in line with manufacturer specifications
Balancing adjustments can help restore airflow distribution once major restrictions are removed

Tom’s Commercial implements airflow corrections without disrupting daily use of the facility. We use accurate diagnostics confirm where pressure is lost, which sections carry the most resistance and what changes will deliver the greatest performance improvement with minimal downtime.

Designing HVAC Systems for Adaptive Reuse and Renovated Commercial Properties

Thu, 13 Nov 2025 20:59:19 GMT

Repurposing older commercial buildings has become a practical alternative in Arlington and Fort Worth, where aging retail centers, warehouses and office shells are often better candidates for renovation than for demolition and rebuilding.

Along corridors like Division Street in Arlington, former strip centers and warehouses are being converted into offices and entertainment venues. In Fort Worth , projects in the Near Southside, Magnolia Avenue and the Stockyards have turned industrial and historic structures into restaurants, breweries and hotels.

These projects give aging buildings new life, but they also introduce HVAC challenges. Heating, cooling and ventilation systems that once served a single-purpose structure rarely translate seamlessly to the demands of modern tenants.

Unique HVAC Challenges in Adaptive Reuse

Mismatched System Design

The most fundamental challenge is that older HVAC systems were sized and configured for an entirely different use. A system designed for one big open space won’t deliver the airflow balance needed in multiple small zones.

Space Limitations

Older buildings often weren’t designed with today’s mechanical standards in mind. Ceiling heights may not allow large duct runs, and structural walls may limit how equipment can be distributed. Mechanical rooms can also be undersized by modern expectations, forcing engineers to get creative with placement or consider compact systems like VRF .

Aging Equipment and Ductwork

It’s common for reused buildings to have outdated rooftop units, boilers or chillers that are inefficient by current standards. Ductwork may be deteriorated or undersized for new layouts. In most cases, keeping the old infrastructure isn’t practical if the goal is efficiency and long-term tenant comfort.

Code and Upgrade Requirements

Existing systems may be grandfathered in, but the moment equipment is replaced or new systems are installed, compliance with current building codes becomes mandatory. In other words, upgrades must be designed with today’s rules in mind even if the building itself is vintage.

Design Considerations for Modern Integration

Recalculated Loads

One of the first steps in designing HVAC for adaptive reuse is recalculating the heating and cooling loads for the new purpose. The original design conditions are irrelevant once the building is subdivided, repurposed or expanded. For example, a warehouse or large retail space converted into offices may have different cooling needs because of increased occupancy, interior partitioning and computer equipment.

Zoning and Controls

Modern tenants expect independent control of their spaces. In an office, different departments may want different temperature setpoints. In retail conversions, showrooms, storage areas and back offices often require different comfort levels. Educational facilities or medical clinics created from older shells may also need strict zoning to maintain consistent conditions. Flexible zoning is essential for balancing comfort and efficiency.

Indoor Air Quality

Ventilation is one of the most important considerations in reuse projects. Old buildings often relied on minimal outside air intake, which is unacceptable by modern standards. Renovated properties need upgraded ventilation systems to meet code and provide fresh, filtered air. Humidity control and high-efficiency filtration may also be necessary depending on tenant use.

Noise Management

Older buildings frequently have hard surfaces and high ceilings that amplify sound. For offices, educational facilities or coworking spaces, noisy HVAC equipment can be disruptive. Selecting quiet systems and designing duct layouts with sound attenuation in mind ensures the mechanical system doesn’t interfere with the tenant experience.

HVAC Technology and System Options for Adaptive Reuse in Arlington and Fort Worth

Variable Refrigerant Flow (VRF)

VRF systems are increasingly popular for reuse projects because they allow flexible zoning without extensive ductwork. They’re efficient, quiet and can adapt to irregular floor plans common in older buildings.

Dedicated Outdoor Air Systems (DOAS)

DOAS units separate ventilation air from heating and cooling loads. This helps buildings with limited duct space meet ventilation requirements while keeping comfort systems efficient.

Hydronic and Hybrid Systems

If the building already has boiler or chiller piping, it may be possible to upgrade the central plant with high-efficiency chillers or hydronic heat pumps. This can reduce installation costs compared with replacing everything.

Balancing Cost and Long-Term Performance

One of the biggest challenges in adaptive reuse is cost. Owners often focus on cosmetic upgrades to attract tenants, but HVAC investments are just as critical.

Well-designed HVAC retrofits reduce tenant turnover, lower utility costs and support the property’s long-term value. Cutting corners during system design often results in higher operating expenses and premature equipment replacement.

We Have Extensive Experience With Adaptive Reuse HVAC Projects

Our team at Tom’s Commercial understands that the needs of modern tenants often can’t be met by inherited HVAC systems. We have developed cost-effective HVAC solutions for all types of reuse projects and would be happy to provide recommendations. Contact our team at 817-857-7400 to schedule a quote or send us an RFP.

How Commercial HVAC Controls Reduce Overhead for Multi-Tenant Buildings

Thu, 13 Nov 2025 20:33:46 GMT

Property owners and facility managers often need to accommodate multiple businesses with different schedules, occupancy levels and comfort expectations. Without the right HVAC controls, they often end up with higher utility bills, disputes over energy use and systems that run longer than necessary.

Modern HVAC control systems are designed to solve these problems. They provide the visibility, precision and accountability needed to keep tenants comfortable while reducing wasted energy. For property owners in Arlington and Fort Worth, where operating costs continue to rise, investing in smart controls is one of the most effective ways to improve profitability without sacrificing tenant satisfaction.

Poor Control in Multi-Tenant Properties Can Be a Drain on Owners

In single-use buildings, HVAC scheduling is relatively straightforward. In a multi-tenant property, the system must adapt to multiple sets of hours and usage patterns. Without advanced controls, the safest way to avoid tenant complaints is to run equipment longer than necessary, which drives up overhead. A well-designed control system ensures energy is used only when and where it’s needed, reducing operating costs without sacrificing comfort.

Improved Tenant Billing Accuracy

One of the most common points of friction in multi-tenant buildings is billing. If tenants are charged based on square footage rather than actual usage, heavy users may be underpaying while low-use tenants subsidize their neighbors. Advanced HVAC controls paired with submeters or zone-level monitoring allow for accurate tracking of energy consumption. Tenants are billed for what they actually use, which not only ensures fairness but also encourages energy-conscious behavior.

Smart Scheduling and Occupancy-Based Controls

Smart controls allow facility managers to program HVAC schedules around tenant hours. A retail tenant that operates evenings and weekends won’t impact an office tenant that only works weekdays. Occupancy sensors can further refine control by reducing output when spaces are empty. This prevents the system from running at full capacity in unoccupied areas, significantly reducing waste.

Energy Benchmarking and Compliance

Even when not mandated, benchmarking is a valuable management tool. Modern control systems generate the data needed to track energy performance over time, compare against standards like ENERGY STAR and identify inefficiencies.

Load Balancing Across Tenants

Uneven system demand is another challenge in shared buildings. A data-heavy tenant with dozens of servers may place more strain on the system than a retail storefront. HVAC controls help balance loads so that no single tenant’s needs overwhelm the equipment or reduce comfort for others. This prolongs system life and helps avoid costly breakdowns.

Remote Monitoring and Centralized Management

Facility managers overseeing multiple properties benefit from the ability to monitor systems remotely. Cloud-based HVAC controls allow performance data and alarms to be accessed from a single dashboard, whether the manager is on-site or off-site. This centralization saves labor costs and ensures issues are addressed quickly, without the need for constant in-person checks.

Integration With Building Automation Systems

Modern HVAC controls often integrate with a building automation system (BAS), tying HVAC performance to lighting, security and other building functions. For example, HVAC can be scheduled to align with lighting schedules, or setback modes can activate when access control systems detect the building is unoccupied. Integration creates additional layers of efficiency and simplifies facility management.

Identifying Maintenance Issues Early

HVAC controls do more than manage schedules and billing. They also collect operational data that can flag potential problems. Rising energy consumption in a specific zone may indicate a failing component, while temperature imbalances can point to duct or damper issues. Early detection allows repairs to be made before they escalate into costly failures, reducing downtime and preventing tenant complaints.

Long-Term ROI for Property Owners

The upfront cost of advanced controls is often outweighed by the long-term benefits. Lower utility bills, extended equipment life and reduced service calls all contribute to lower operating expenses for owners. Accurate billing also improves tenant relations by eliminating disputes over energy charges. In competitive leasing markets like Arlington and Fort Worth, buildings with modern, efficient systems stand out to prospective tenants.

Reduce Heating and Cooling Overhead With Smarter Controls in Your Fort Worth Facility

In multi-tenant buildings, HVAC is one of the largest contributors to overhead. Outdated or poorly managed systems can waste thousands of dollars annually in unnecessary energy use.

Emergency HVAC Preparedness for DFW’s Extreme Weather

Wed, 12 Nov 2025 20:51:22 GMT

North Texas facilities got a harsh reminder of infrastructure vulnerability during the February 2021 winter storm. Days of below-freezing temperatures and widespread power outages left many commercial buildings unable to maintain heat or basic freeze protection. For facility managers in Arlington and Fort Worth, the lesson was clear: you can’t prevent severe weather, but you can prepare your HVAC systems and emergency protocols to respond more effectively.

Determine Which Operations Must Stay Online

The first step in emergency planning is to define what “must run” during an outage. Some office tenants can work from home if power is down, but other facilities, such as healthcare centers, data facilities and warehouses storing temperature-sensitive products, don’t have that luxury. Facility managers should identify critical HVAC loads in advance and make sure contingency plans prioritize them.

What Backup Power Can and Can’t Do

Backup generators are often seen as the answer to outages for facilities that can’t afford any downtime, but they do have limitations when it comes to HVAC. Many commercial properties in DFW rely on gas-fired boilers or rooftop units for heating. While natural gas is usually reliable, it isn’t guaranteed during regional crises.

Even if gas is available, boilers and HVAC units still require electricity for circulation pumps, blowers and controls. A typical generator can’t cover the entire system, but it can be sized to keep essential pumps, control panels and limited heating zones operational.

This distinction is critical. Generators are not a substitute for full heat delivery, but they can preserve infrastructure and buy time until grid power is restored.

Protecting Equipment and Piping During Outages

Even when full heating isn’t possible, steps can be taken to avoid catastrophic damage:

Drain and isolate cooling towers or idle loops if extended freezing conditions are expected.
Ensure mechanical rooms have localized heat sources (portable or generator-powered) to protect pumps and controls.
Verify pipe insulation and heat tracing are functional to reduce freeze risk in exposed areas.

These measures don’t keep the building comfortable, but they prevent expensive equipment failures and burst pipes.

Rapid Restart Protocols After Power Returns

The return of grid power can be as dangerous as the outage itself. A simultaneous restart of all HVAC systems may overload electrical infrastructure or reveal equipment damaged by the freeze. Facilities should have staged restart procedures . This usually entails bringing on critical systems first, then secondary zones. This reduces stress on both utility connections and the equipment itself.

Remote Monitoring and Alerts

Extreme weather often prevents staff from reaching the property quickly. Cloud-based HVAC controls and BAS platforms allow managers to see when systems go offline, when temperatures drop in vulnerable zones or alarms are triggered. This visibility makes it possible to act faster, even if crews can’t immediately get on site.

Communication With Tenants and Staff

A clear emergency communication plan ensures tenants know when non-critical spaces may lose temperature control and when backup systems are in operation. Clear messaging helps manage expectations and avoids unnecessary conflict when comfort can’t be guaranteed during a regional emergency.

Investing in Long-Term Resilience

No system can make a building immune to widespread power and gas failures, but upgrades can reduce risk:

Dual-fuel or hybrid systems provide more flexibility during supply disruptions.
High-performance insulation and weatherization reduce how quickly indoor conditions deteriorate when systems go offline.
Load-shedding controls allow facilities to ration generator power to the most essential HVAC components.

These investments require upfront cost but can be phased in and tied to other capital projects.

Ensure Your Facility’s HVAC System Is Prepared for the Next Major Winter Weather Event

The 2021 storm showed that even in a region better known for heat, prolonged cold and outages are possible.

Emergency HVAC planning doesn’t mean keeping every tenant perfectly comfortable during a blackout. It means protecting equipment, maintaining critical operations and ensuring the building can recover quickly when conditions stabilize.

How Commercial Buildings Can Prepare for DFW Fall and Winter Weather

Mon, 03 Nov 2025 20:12:23 GMT

Long cooling seasons are typically the focus of HVAC system design in North Texas. While the region doesn’t see months of heavy snow like northern states, sudden cold fronts, ice storms and occasional hard freezes can still disrupt operations and cause costly damage.

Preparing HVAC systems and building infrastructure for these seasonal shifts helps facility managers avoid emergencies, reduce downtime and keep tenants comfortable.

Hope for the Best, But Prepare for the Worst

Typical fall and winter days in North Texas bring mild temperatures. But the region is also prone to “blue northers”—fast-moving cold fronts that can drop temperatures by 30 degrees in a matter of hours. Ice storms are more common than snow, but they can be equally dangerous, coating rooftops and stressing drains.

The years between severe, prolonged freezes can lull property owners and managers into a false sense of security. It only takes one disastrous and expensive winter weather event to remind building owners that local infrastructure isn’t built for sustained subfreezing conditions.

That’s why it’s best to prepare your HVAC system as if this winter will be one for the history books. It’s better to be pleasantly surprised by mild temperatures than to be chagrined by frozen pipes and failed rooftop units that require you to spend thousands of dollars on emergency repairs .

Preventive HVAC Maintenance Before the Season Changes

A fall maintenance visit is the most cost-effective step in preparing a commercial building for colder weather. Common tasks include:

Inspecting heat exchangers and burners to ensure combustion systems operate safely and efficiently.
Checking belts, motors and filters so airflow isn’t restricted once heating demand increases.
Calibrating thermostats and controls to verify they respond properly to both heating and cooling commands.
Testing emergency shutoffs and safety controls before equipment is put under stress.

Regular maintenance not only prevents breakdowns but also ensures a smoother transition between cooling and heating modes.

Freeze Protection for Vulnerable Systems

Even though deep freezes are rare, they can be damaging. Buildings with exposed piping, rooftop units or cooling towers should have basic freeze protection measures in place:

Pipe insulation for exposed water lines and condensate drains.
Heat trace systems where water must remain flowing.
Drainage checks to make sure water isn’t pooling on rooftops where it can freeze and create hazards.
Verification of heat strips and coil heaters in air handlers.

Many of these measures require minimal investment but protect against catastrophic failures during hard freezes.

Storm Readiness for Rooftop Equipment

Fall in DFW often brings severe thunderstorms and high winds. Rooftop HVAC units and other equipment should be secured against shifting or vibration. Facility managers should also ensure roof drains are clear so heavy rain or ice doesn’t cause ponding, and that access panels are fastened properly to avoid wind damage.

Proactive checks reduce the chance of roof leaks or equipment damage during storms.

Balancing Heating Loads in Multi-Tenant Buildings

In multi-tenant or open-plan commercial spaces, heating demands can vary widely, and not just because of variation in tenant usage. South-facing spaces warm quickly from sun exposure, while shaded zones stay cooler. Without proper controls, this can lead to uneven comfort and wasted energy.

Zoning and smart controls help distribute heat efficiently across different tenants or departments. This not only improves comfort but also reduces overhead by preventing unnecessary runtime.

Monitoring and Adjusting During Rapid Shifts

DFW weather can change overnight. Smart HVAC controls allow facility managers to adjust settings remotely, ensuring the system responds quickly to unexpected cold snaps or sudden warm-ups. Monitoring energy data during these shifts can also flag equipment issues early, such as a heat pump struggling to meet demand or a gas furnace short-cycling.

Long-Term Payoff of Seasonal Preparation

The cost of fall and winter prep is minor compared to the potential consequences of ignoring it. Frozen pipes, failed rooftop units or comfort complaints from tenants can quickly escalate into expensive repairs and lost revenue.

By addressing maintenance, freeze protection, storm readiness and load balancing ahead of time, commercial property owners in Arlington and Fort Worth safeguard both their buildings and their bottom line.

Stay Ahead of DFW’s Fall and Winter Heating Challenges

Even in a region better known for air conditioning than heating, seasonal preparation pays off. North Texas winters may be short, but they’re also notoriously unpredictable. Facility managers who take proactive steps in the fall position their buildings for lower costs, fewer emergencies and greater tenant satisfaction.

The Hidden Impact of HVAC Noise on Productivity and Tenant Satisfaction

Thu, 23 Oct 2025 23:00:59 GMT

Not all HVAC issues show up as hot and cold complaints. In many commercial buildings, especially those with open ceilings or shared walls, noise becomes the first sign that something’s off. A loud rooftop unit, rattling ductwork or persistent humming might seem harmless at first, but over time, these distractions can affect employee focus, customer experience and tenant retention.

HVAC systems don’t have to be silent, but when background noise turns into a regular source of irritation, it’s worth investigating. In some cases, mechanical problems are the cause. In others, the issue comes down to installation quality, airflow design or aging components.

Regardless of the cause, if people in your building are bothered enough to complain, it’s worth your attention.

Common Types of Problematic HVAC Noise

What counts as “excessive” depends on the space and the business. A sound that’s tolerable in a warehouse might be unacceptable in a law office or preschool. But some types of HVAC noise tend to create problems across most environments:

Rattling or banging, which is often caused by loose panels, deteriorating fan blades or unstable rooftop unit mounts.
Buzzing or humming sounds may indicate failing electrical components like contactors or transformers, and the vibration could be transferring through walls or ceilings.
High-pitched squealing, which usually indicates motor bearing wear or a slipping belt.
Whooshing or whistling airflow can result from undersized or restricted ducts, improperly sealed fittings or airflow imbalance.
Frequent cycling sounds may create disruptive audio spikes multiple times per hour.

Even if these sounds aren’t accompanied by a decrease in system performance, they may still interfere with productivity and comfort.

Noise Matters in All Types of Commercial Spaces

In shared office spaces, schools and medical environments, sound travels. It doesn’t take much additional HVAC noise for occupants to notice or comment on the disruption.

In offices, constant rattling, high-pitched fan sounds or the added distraction of short cycling can make it harder for employees to concentrate or conduct calls. Over time, this contributes to fatigue and frustration.
In tenant-occupied spaces, noise complaints may show up as part of lease negotiations or satisfaction surveys. If tenants perceive that HVAC issues are being ignored, it can impact retention.
In customer-facing businesses, visitors may associate buzzing, groaning or duct vibration with poor maintenance or low quality, even if comfort levels are fine.

If tenants or customers are complaining, it may be worth your time to look into the root cause and solutions.

When HVAC Noise Signals a Bigger Problem

Not all noise is urgent, but certain patterns are worth acting on before they turn into more expensive service calls:

A sudden change in volume or sound type (e.g., from low hum to grinding)
Complaints from occupants paired with airflow or temperature inconsistencies
A noise that occurs more frequently, such as short cycling every few minutes
Signs of metal-on-metal contact, like rattling ducts or scraping fan blades

If you’ve ruled out external causes and the noise seems to originate from the system itself, it’s time for a technician to take a closer look.

How Tom’s Commercial Can Help Reduce HVAC Noise and Improve Comfort

If your building’s HVAC system is creating more background noise than it used to, or if tenants and employees are starting to complain, we can help. Tom’s Commercial offers expert diagnosis of noise-related HVAC issues, including:

Mechanical inspections to identify loose or degraded components

Preparing HVAC Systems for Load Shifting and Utility Demand Response Programs

Thu, 23 Oct 2025 22:55:14 GMT

The dramatic increase in electricity demand during summers in Arlington and throughout DFW can push the power grid to the breaking point. In June 2023, the Electric Reliability Council of Texas (ERCOT) reported a new all‑time high peak demand of 80,828 MW , triggering statewide appeals to conserve energy to keep blackouts at bay.

DFW is the nation’s largest metro area by square footage. Our 9,200 square miles are bigger than Connecticut and Rhode Island combined. From a population perspective, DFW is the fourth largest metro area in the U.S.

That’s a lot of people and a lot of buildings that require consistent cooling in persistent triple-digit summer temperatures. Commercial buildings aren’t the top electricity consumers overall, but they often represent the most controllable load (especially HVAC), making them prime candidates for demand response (DR) programs.

Utilities want to reduce the risk of blackouts, and they’re more than happy to incentivize participation in demand response programs to make them less likely.

What Is HVAC Load Shifting?

Load shifting refers to the practice of changing when and how your HVAC system consumes electricity to reduce demand during peak hours. Instead of cooling a space continuously throughout the hottest part of the day, you might:

Pre-cool in the morning before occupancy peaks
Temporarily raise thermostat setpoints during peak hours
Cycle units or stagger fan/compressor loads
Disable cooling in non-critical zones

With the right controls in place, these actions can be automated or scheduled to align with rate structures, occupancy and weather patterns.

Demand Response Programs for Arlington and DFW Businesses

Several demand response programs are available to commercial electricity users in the DFW area, but they are voluntary, not mandatory. Businesses must opt in through a retail electric provider (REP), energy aggregator or direct enrollment with ERCOT. Some common DR pathways for Arlington and DFW facilities include:

ERCOT Load Resource and Emergency Response Service (ERS) programs
Aggregator-managed programs via providers like Enel , CPower or Voltus
REP-sponsored curtailment incentives for large commercial accounts

Participants typically receive event alerts, and agree to reduce load during a defined window, often between 3 p.m. and 7 p.m. HVAC curtailment usually involves:

Raising thermostat setpoints 2–4°F in occupied spaces
Cycling units in stages to avoid peak overlap
Temporarily disabling HVAC in low-use or storage zones

In return, commercial buildings may receive:

Credits or rebates for participation or verified load reductions
Lower demand charges
Incentives tied to green building certification or ESG goals

Do Facilities Require Special Equipment to Participate?

Not necessarily, but buildings with modern zoning, variable-speed components and networked thermostats are more likely to succeed in DR programs without sacrificing comfort.

Is It Worth Upgrading to Enroll?

Only if you’re already planning improvements. Swapping in variable-frequency drives (VFDs), multi-stage compressors or advanced controls can help you automate participation, but the upfront investment won’t be fully offset by DR credits or demand charges.

However, facilities that need to replace their HVAC system can benefit from choosing equipment that enables program participation while minimizing the impact on occupant comfort.

How to Prepare Your HVAC System for Load Shifting

Even without a formal DR agreement, load shifting can reduce utility bills during high-rate periods. Facility managers and property owners may want to:

Use a BMS or programmable thermostat to automate pre-cooling and peak setbacks
Review occupancy patterns to identify zones that can tolerate reduced cooling
Stagger start/stop times on rooftop units to avoid power spikes
Track runtime and cycling frequency to avoid overworking specific components
Coordinate with lighting and plug-load strategies for broader demand reduction

Facilities with flexible HVAC zoning, modern controls or recent upgrades will typically have an easier time implementing these changes without complaints.

Is It Worth Upgrading HVAC Equipment to Support Load Shifting?

Not unless you’re already replacing aging units or redesigning your control strategy. If upgrades are on the table, you can support future DR participation or load-shifting flexibility by investing in:

Variable-speed fans and compressors that allow you to scale performance instead of cycling on/off
Advanced thermostats or BMS integration to automate participation or manual curtailment
Smarter zoning to isolate critical and non-critical areas for targeted load reduction
Demand-controlled ventilation (DCV) that allows you to adjust airflow based on occupancy or air quality, not just a clock

If your building lacks these features, you can still participate, but the impact (and savings) may be smaller.

Load Shifting Can Go Too Far

Load-shifting isn’t risk-free. If executed poorly, it can lead to:

Occupant complaints due to overly aggressive temperature changes
IAQ issues if fan cycling is reduced too much
System strain if units short cycle while trying to recover
Uneven comfort across zones, especially in open-concept buildings

Successful participation requires striking a balance between energy savings and tenant satisfaction.

How to Interpret Commercial HVAC Performance Data From Your BMS System

Thu, 23 Oct 2025 22:45:48 GMT

Facility managers who oversee buildings with a Building Management System (BMS) typically have at least a passing familiarity with performance data and how it can be used to track HVAC behavior, energy usage and occupant comfort. The challenge is knowing when data points signal something worth acting on and when they’re just noise.

Whether your building uses a modern, cloud-based platform or a legacy BMS with limited visuals, HVAC data is only useful if it helps you identify inefficiencies, prevent downtime or make smarter maintenance decisions.

What HVAC Metrics Does a Typical BMS Track?

A BMS can surface hundreds of data points, but for monitoring HVAC performance, the key metrics include:

Zone temperatures and humidity
Fan speeds and variable frequency drive (VFD) output
Static pressure and cubic feet per minute (CFM) airflow
Supply and return air temperatures
Runtime hours and compressor cycling
Setpoint compliance and override frequency
Fault or alarm codes
Energy use or demand per zone/unit

Depending on your system’s age and how your BMS was configured, you may only see some of these, or you may be pulling far more granular data. What matters most is knowing which trends are most impactful for occupant comfort, efficiency and system health.

Which Data Points Actually Matter for Maintenance Planning?

Even if all zones are reporting within range and no alarms have been triggered, you can still spot early signs of stress or imbalance by watching how performance changes over time.

Runtime hours and cycling frequency can help you predict which units may need attention before they fail. If compressors are short cycling or fans are running continuously, you may be dealing with airflow restrictions or control issues.
Even small deviations from setpoints can signal duct leaks, damper failures or degraded insulation. If a zone can’t meet setpoint despite extended runtime, the issue may not be software-based.
Airflow readings and static pressure help indicate whether your duct system is balanced and clean. A slow increase in pressure over time could point to filter clogging or obstructions.

When these metrics are tracked over time, which most BMS platforms do automatically, small patterns often become visible weeks before anyone reports a comfort complaint.

How to Spot Warning Signs in BMS Reports

Alarms aren’t the only way your BMS warns you something’s off. Some data trends that may indicate emerging HVAC problems include:

Sudden drops or spikes in airflow to one or more zones
Repeated manual overrides from occupants or staff trying to “fix” temperature problems
Frequent after-hours operation that doesn’t align with building schedules
Zones that consistently fail to recover after weekend setbacks

These patterns may not trigger alerts, but they often point to sensor drift, actuator failures or underperforming equipment. Catching them early can save thousands in emergency service calls or energy waste.

Common Mistakes Facility Teams Make When Monitoring BMS Data

Relying only on alarms : Alarms are reactive by nature. Waiting for one means a problem has likely already escalated.
Ignoring long-term efficiency drift : If cooling takes 20% longer to hit setpoint than it did six months ago, something’s changed, even if occupants aren’t lodging complaints.
Misreading seasonal variability : Some fluctuations in data are normal, but comparing year-over-year trends during the same season gives a clearer picture of mechanical wear or control drift.
Not updating BMS schedules : Building usage often changes, especially in schools, churches and shared spaces. Outdated setpoints or occupied/unoccupied schedules can drive up energy use without improving comfort.

Practical Ways to Leverage BMS Data

Making a Business Case for Repairs or Upgrades

When it’s time to justify HVAC spending, whether for a major repair , retrofit or equipment replacement , BMS data can provide the hard evidence you need.

Showing a pattern of runtime increases, persistent setpoint failures or frequent overrides paints a clear picture that the issue isn’t isolated or occupant error. In schools, churches or corporate environments where budget approvals involve leadership or board review, this kind of documentation can make the difference between a deferred project and a green light.

Verifying That Repairs Actually Solved the Problem

After a technician services your HVAC system, your BMS can help confirm that the issue is truly resolved. If a unit was short cycling, failing to meet setpoints or running overtime, reviewing post-repair data can show whether the behavior has normalized. It also helps detect partial fixes, or cases where the immediate symptom is gone but underlying airflow, zoning or load problems still exist.

Using performance trends to validate the outcome of repairs before occupants complain that you failed to fix the problem can lead to better overall tenant satisfaction.

Make the Most of Your Arlington Facility’s BMS Data

Your BMS provides powerful HVAC data, but it doesn’t provide any value without monitoring and proper interpretation. By paying attention to trends, planning maintenance proactively and seeking support when something doesn’t add up, facility managers can keep their systems running efficiently without relying on alarms or guesswork.

Is Retrofitting a Commercial HVAC System a More Affordable Alternative to Replacement?

Thu, 23 Oct 2025 22:37:22 GMT

For facility managers and property owners saddled with an aging HVAC system, there’s always a point where something major breaks and you’re forced to ask the big question: do we replace the system entirely or try to repair and retrofit what’s already there?

Retrofitting often feels like a smarter short-term move, especially when budgets are tight or the owner is thinking about selling. But is it actually a more affordable long-term solution?

The answer depends on your system’s age, condition and performance, as well as your building’s size, insulation, layout and the goals you’re trying to achieve. In some cases, retrofitting can buy you years of additional performance at a fraction of the cost of a full replacement. In others, it ends up costing more in repairs, inefficiencies and lost productivity.

What Does an HVAC Retrofit Involve?

Retrofitting refers to upgrading or replacing specific components within your existing HVAC system to improve performance, energy efficiency or compatibility with newer controls and refrigerants. It’s distinct from repairs, where broken or worn components are simply replaced with the same or comparable parts. Common commercial HVAC retrofits include:

Replacing outdated air handlers or condensers
Installing variable frequency drives (VFDs) on fan motors
Upgrading to more efficient thermostats or building automation controls
Adding economizers or demand ventilation systems
Swapping out obsolete refrigerants or metering devices

Retrofits can range from relatively simple add-ons to complex mechanical overhauls. The key difference is that the core infrastructure, like ductwork, piping and electrical systems are largely preserved.

When Is Retrofitting a Viable Option?

Not every HVAC system is a good candidate for retrofitting. The most viable systems tend to meet several criteria:

Still structurally sound : The ductwork, air handlers and core system components are intact and functioning.
Under 20 years old : While some older systems can be retrofitted, the closer they are to end-of-life, the less ROI a retrofit offers.
Consistent building use : If your facility has steady occupancy and moderate environmental demands (like an office, school or house of worship), retrofitting can often meet those needs without a full system swap.
No major changes planned : If you’re not planning a renovation, expansion or significant change in occupancy, retrofitting allows you to extend the current system’s life without overhauling everything.

Comparing Costs: Retrofit vs. Replacement

In most cases, retrofitting costs less upfront than replacing your HVAC system. A full replacement often involves:

New equipment
Duct redesign
Electrical or structural work
Downtime and logistical disruptions

Retrofitting minimizes these expenses. You’re only replacing what’s necessary. In many cases, a targeted retrofit might extend system life by five to ten years, giving you time to budget and plan for future replacement. There may also be better HVAC equipment available by the time you need to replace it, and upgrading to a more efficient system may be more affordable.

What You Might Lose by Avoiding Full Replacement

While retrofits can make sense financially in the short term, there are trade-offs:

Reduced performance: Older systems may have poor airflow design, inefficient duct routing or limited compatibility with modern high-SEER equipment.
Limited efficiency gains : Older components, even when upgraded, won’t reach the energy performance of a brand-new system.
Partial compatibility : Mixing old and new components can lead to suboptimal performance or maintenance challenges down the line.
Fewer incentive opportunities : Utility rebates and tax incentives often require full system upgrades to qualify.
Shorter life extension : Retrofitting rarely adds more than 5–10 years of usable life. A new system could give you 20+.

If your goal is long-term stability, predictability and lower maintenance, a full replacement may actually be the better value, particularly if your current system is already nearing the end of its useful life.

Signs That It’s Time to Consider Full Replacement Instead

Retrofitting makes sense when the system still has life left in it. If you’re dealing with any of the following, though, it may be time to stop putting off a full replacement:

The system is more than 20 years old
You’ve had multiple component failures in the past two years
Occupants are consistently complaining about noise, temperature or air quality
Your building’s use or occupancy is about to change dramatically
Old replacement parts are becoming harder to source or service

Are Texas Property Owners Held Liable for Injuries Caused by HVAC Failure?

Fri, 26 Sep 2025 22:03:09 GMT

Commercial and multi-family residential property owners have understandable liability concerns. Slip and fall accidents can be a massive and expensive headache to deal with, and the potential causes are seemingly limitless. With so much focus directed at things like handrails on stairs and fire exits, it’s unsurprising that some property owners fail to give much thought to temperature-related risks.

HVAC Obligations for Texas Property Owners

HVAC requirements for Texas landlords can be complicated. Property Code § 92.052 only requires landlords to repair conditions that “materially affect the physical health or safety of an ordinary tenant.” That typically applies to existing systems. If the lease says the unit comes with AC (or it’s implied), the landlord must keep the AC working. If the property never had AC, there’s no statewide requirement to install it.

Some cities do have local ordinances requiring landlords to provide AC in rental housing, including Dallas and Austin. Houston is a bit more complicated, only requiring AC if the rental unit doesn’t have ‘properly screened windows’ that can be opened.

Fort Worth and Arlington do not have a local ordinance requiring landlords to provide AC unless it’s expressly or impliedly included in the lease agreement. In other words, if you rent out a residential property with air conditioning or a heat pump, and it breaks, you would be required to repair it as a condition that affects physical health or safety.

From a Liability Standpoint

If a rental property or commercial facility doesn’t have an air conditioner and the lessee has no expectation of cooling, a property owner likely can’t be held liable for heat-related injuries or deaths. However, if the property does have an AC or heat pump, and it breaks, the property owner could potentially be held liable for injuries attributable to their failure to fix it.

Although an air conditioner or heat pump isn’t a legal requirement for Arlington and Fort Worth multi-family properties, it is practical necessity. There are very few rentals in the metro area that don’t have some form of cooling because there’s not much of a market for rentals that are virtually uninhabitable for much of the year.

Heat Liability in Commercial Settings

Employers are required under OSHA’s General Duty Clause to provide a workplace free from recognized hazards. That includes excessive indoor heat in warehouses, distribution centers and other commercial facilities.

Even though OSHA does not have a formal indoor air conditioning requirement, the agency has cited businesses for failing to protect workers from heat stress. In practice, this means if an HVAC system fails and employees experience heat illness, the property owner or manager could face fines, insurance complications or civil liability claims.

Preventive HVAC Maintenance as Liability Protection

One of the most effective ways property managers can reduce liability exposure is by prioritizing preventive HVAC service. Regular inspections and tune-ups catch issues like failing capacitors, refrigerant leaks or airflow restrictions before they lead to complete system failures during the hottest days of summer.

In addition to keeping tenants and employees safe and comfortable, staying on top of preventive HVAC maintenance demonstrates a good-faith effort to uphold health and safety obligations. If a dispute ever does arise, being able to show maintenance records can be a powerful defense, because it proves that management took reasonable steps to maintain the property and minimize heat-related risks.

Cold Weather Risks Shouldn’t Be Overlooked

The notorious 2021 winter storm was a stark reminder of how heating failures can lead to dangerous and even deadly conditions in the DFW area. Just like with air conditioning, Texas law requires landlords to repair heating equipment if it breaks and threatens tenant health or safety.

For commercial facilities, inadequate heating can also disrupt operations, damage equipment and expose employees to unsafe working conditions. A comprehensive maintenance plan that covers both heating and cooling ensures year-round protection.

Controlling Indoor Air Quality in Sensitive Commercial Facilities

Mon, 22 Sep 2025 21:59:29 GMT

While indoor air quality should be a concern for every commercial facility, it’s not a vital concern in every workplace. Offices should want good air quality to keep employees and visitors happy and healthy, but IAQ isn’t exactly foundational to the work product.

IAQ can be much more important in healthcare facilities, laboratories, food processing plants and many types of industrial buildings where contaminants in the air can compromise safety, damage products and even threaten human health.

Common IAQ Challenges in Sensitive Facilities

Healthcare Settings

Patient health depends on strict air quality control to minimize the spread of airborne pathogens, allergens and irritants. Humidity levels must be balanced to reduce microbial growth while ensuring comfort for patients and staff.

Laboratories and Cleanrooms

Some work areas require ultra-low particulate counts, consistent pressurization and controlled airflow to protect research integrity and sensitive experiments. Even small deviations can ruin test results or contaminate products.

Food Processing Plants

Uncontrolled IAQ can compromise sanitation, leading to microbial growth on surfaces and equipment, shorten the shelf life of food, compromise packaging integrity or exacerbate cross-contamination risks. IAQ issues can lead to failed inspections, production pauses and expensive corrective actions.

Industrial facilities

Dust, fumes, vehicle exhaust and airborne byproducts from manufacturing processes are all common challenges in industrial facilities. Left unchecked, these contaminants can harm employees, damage machinery and create long-term safety concerns.

Core Strategies for IAQ Control

Filtration

Upgraded filters with higher MERV ratings are often required in sensitive spaces. These filters capture finer particulates than standard options, protecting both people and equipment from microscopic contaminants.

Ventilation

Bringing in and conditioning outside air dilutes contaminants that accumulate indoors. Proper ventilation design is especially important in tightly sealed buildings, where recirculated air can otherwise trap pollutants.

Humidity Control

Maintaining the right humidity balance reduces microbial growth, protects sensitive products, and prevents moisture damage to equipment. For healthcare and food processing environments, humidity management is especially critical.

Airflow Management

Pressurization strategies and controlled air circulation ensure contaminants move away from clean or sensitive zones and toward exhaust. Optimized airflow is often essential in labs, cleanrooms and medical facilities.

Retrofitting Existing Systems

Improving indoor air quality doesn’t always require replacing entire HVAC systems. Many facilities can retrofit their existing equipment with targeted upgrades. Some of the options include:

Moving from standard MERV 8 filters to higher-efficiency filters, such as MERV 13 or HEPA, where airflow allows.
Installing UV-C light systems inside air handlers to neutralize bacteria, mold spores and viruses as they pass through.
Adding bipolar ionization units to ductwork to reduce particulates and pathogens.
For buildings where outdoor ventilation rates are inadequate, a dedicated outdoor air system (DOAS) can be added to supplement fresh air without overloading existing cooling capacity.

Improving Ventilation Balance

IAQ problems often come from how air is distributed, not just how it’s filtered. Adjusting ventilation balance is one way to control contaminant movement in sensitive facilities.

Positive pressure can be created in clean spaces such as labs, surgical areas or packaging rooms, while negative pressure can be used in isolation areas or places where contaminants must be contained.

Retrofitting ductwork with additional dampers or installing variable air volume (VAV) boxes allows facility managers to fine-tune zoning and airflow, reducing the risk of cross-contamination.

Humidity Management Solutions

In food processing plants and sensitive research labs where humidity control is a high priority, retrofitting systems with standalone dehumidifiers or integrating desiccant wheels helps keep moisture levels in check.

In manufacturing facilities or other environments where static electricity risks from low humidity are an issue, adding steam or ultrasonic humidifiers can help ensure dry conditions don’t disrupt operations.

Monitoring and Controls

Even the best equipment upgrades fall short without accurate monitoring. Real-time IAQ sensors measuring CO₂, VOCs and particulates give facility managers clear data on indoor conditions. Connecting those sensors to a building automation system (BAS) allows ventilation rates, filtration and humidity controls to adjust automatically when air quality starts to drift.

This type of control keeps IAQ consistent and provides a record of conditions that can be useful during audits, inspections or client reviews.

Optimize Your Fort Worth or Arlington Facility’s IAQ With the Help of Tom’s Commercial

In DFW, where extreme weather and less-than-perfect air quality put additional strain on HVAC equipment , proactive IAQ management is a must. Don’t wait until a complaint, inspection failure or breakdown forces your hand. Contact Tom’s Commercial today at 817-857-7400 to schedule service or request a consultation.

Reducing Business Interruption from System Failures

Fri, 19 Sep 2025 21:53:59 GMT

HVAC outages are disruptive to any organization or commercial facility, whether it’s a manufacturing facility, doctor’s office or school. However, the consequences of temperature control and IAQ failures can vary dramatically depending on the facility.

A school or retail facility might be able to continue operating relatively normally while a manufacturer may need to temporarily cease operations. In some healthcare or IT environments, even a temporary HVAC outage can damage equipment or lead to the loss of work product.

Redundancy in Temperature and IAQ Control

In environments like data centers, laboratories, food processing plants and many healthcare spaces, where tight control of temperature, humidity or air quality is essential, redundancy is often built into the system design.

Some facilities pair multiple rooftop units to serve the same zone, so if one goes down the other can carry part of the load. Others keep backup fans or secondary air handlers tied into the duct system, ready to activate if a motor or blower fails. These solutions don’t eliminate risk entirely, but they give property managers valuable time and flexibility, reducing the likelihood of costly disruptions while repairs are underway.

While not every commercial property needs this level of HVAC investment, redundancy provides peace of mind in facilities where downtime is unacceptable and the cost of product loss or system disruption far outweighs the price of additional equipment.

What an HVAC Outage Contingency Plan Looks Like

For facilities without full redundancy, contingency planning becomes the next best protection. A good plan usually starts with a maintenance program that lowers the risk of sudden failure. Beyond that, managers should identify the specific vulnerabilities of their building:

Which areas would be impacted first if cooling is lost?
How long can critical areas remain stable without active cooling or ventilation?

The answers inform what backup measures make sense:

In food facilities, that might mean portable chillers staged for emergencies.
In healthcare, it might include arrangements for patient relocation if a critical space loses climate control.
In office or retail, it could be as simple as pre-arranging rapid response with a trusted HVAC service provider.

The key is to avoid scrambling in the middle of an outage. A written plan with vendor contacts, priorities and timelines reduces stress and speeds up recovery.

Emergency Response Steps

When a failure does occur, a clear response plan helps limit disruption.

Staff need to know how to recognize signs of equipment distress, such as tripped breakers, loss of airflow or abnormal noises, and who to notify.
Communication with tenants, employees or customers should be straightforward. Acknowledge the problem, explain expected timelines and outline immediate steps being taken.
A designated commercial HVAC service provider with fast-responding emergency service capabilities should have access to the building and any prior maintenance records so they can diagnose and resolve the issue quickly.
Facilities that prepare in advance with key contacts, access procedures and communication templates bounce back faster and with fewer long-term consequences.

Temporary Cooling and Redundancy Options

For facilities where full system redundancy isn’t practical, portable and supplemental equipment can bridge the gap during an outage. Portable spot coolers or mobile AC units can be staged in warehouses, server rooms and healthcare spaces to maintain safe conditions until permanent systems are back online. In industrial settings, temporary cooling towers and rental chillers can be deployed to protect processes or equipment.

The ROI of Proactive Rooftop HVAC Maintenance in DFW

Wed, 17 Sep 2025 21:48:30 GMT

Rooftop HVAC units have an ‘out-of-sight-out-of-mind’ problem. Unless there’s a major breakdown, property managers often assume the equipment is doing fine. This attitude is especially common among businesses that deliberately or inadvertently budget reactively and address facility infrastructure issues only when they arise.

In other cases, facility managers may even have a maintenance agreement in place , but visits get skipped or checklists aren’t fully completed, and nobody notices because oversight of HVAC technicians typically isn’t thorough.

The result is the same: higher operating costs and shorter equipment lifespan. Ignoring or delaying maintenance isn’t cost-neutral; it creates hidden expenses that eventually show up in utility bills, repair invoices and premature replacement costs.

The Energy Efficiency Benefits of Maintenance

Energy efficiency is one of the most immediate ROI drivers of proactive maintenance. Dirty coils, clogged filters or weak components make rooftop units work harder to deliver the same amount of cooling. That wasted effort shows up on monthly energy bills.

A well-maintained rooftop unit consumes less electricity while it’s running. Even modest efficiency gains of 10 to 15 percent can translate into thousands of dollars in annual savings for a large building or a portfolio of properties.

Extending Equipment Lifespan

Rooftop units are capital investments, not disposable equipment. With proper care, they can provide reliable service for 15 to 20 years. Without it, they may suffer component failures that cascade into larger system damage, forcing owners into costly, premature replacements.

On the other hand, preventive maintenance addresses small wear-and-tear issues before they become catastrophic. Spending a little each year on tune-ups protects against six-figure replacement costs and keeps capital budgets predictable.

Reducing Repair Costs

It’s not an exaggeration to say that some catastrophic HVAC failures can be prevented with routine service. A worn belt or weak capacitor costs very little to fix. However, if left undiagnosed and unresolved, those same issues can take out a compressor or motor, resulting in repairs that can cost thousands and disrupt operations.

Preventive maintenance reduces the frequency and severity of repairs by identifying and resolving minor issues early. It transforms unpredictable, emergency repair bills into manageable, planned expenses.

Capital Budgeting

Regular inspections create a record of each rooftop unit’s condition, allowing property managers to make informed decisions about when to replace or upgrade equipment. Instead of being blindsided by multiple units failing in the same season, managers can phase replacements strategically.

Predictability makes long-term capital budgeting far easier.

Tenant, Customer, and Employee Satisfaction

Comfort is part of the value property owners offer tenants. Customers and employees expect dependable temperature and humidity control in commercial buildings, and tenants are obviously more likely to renew leases in properties where HVAC is effective and reliable.

Employees are more productive and customers more willing to linger in spaces that are comfortable year-round.

While the connection between comfort and ROI may be indirect, the impact on tenant retention, customer loyalty and workforce stability is real. When skimping on maintenance negatively impacts indoor comfort, it can damage those relationships in ways that cost far more than a service contract.

Why Lifecycle Cost Analysis Beats “Lowest Bid” Thinking in HVAC Replacement

Wed, 27 Aug 2025 19:57:08 GMT

When commercial HVAC systems reach the end of their service life, the first instinct is often to compare bids and pick the lowest price. But installation cost is only a fraction of total heating and cooling expenditures over the course of a system’s lifespan. Lifecycle cost analysis (LCA) looks beyond the installation number, helping building owners and property managers evaluate total ownership, including performance, energy use, maintenance requirements and longevity, before committing to a replacement .

Performance and Reliability

Low-bid equipment often meets minimum code but not long-term performance goals. Compressors, coils and controls may be selected primarily to cut upfront expense, which can compromise temperature control and system balance once installed. In multi-zone buildings or facilities with sensitive equipment, those inconsistencies can mean higher humidity, more noise and frequent service calls.

Being able to accurately predict how a system will perform throughout its lifespan, not just when it’s new, is vital. Factoring in load requirements, control responsiveness and expected wear allows decision makers to choose equipment that will maintain stable indoor conditions for the full duration of its operating life. Over time, steady performance translates to lower total operating costs and fewer disruptions for tenants or employees.

Equipment Longevity

Facility managers and property owners understand durability is important, but concerns about system lifespan frequently take a back seat to the upfront cost of HVAC replacement. Lower-priced systems often use thinner metals, lower-grade coatings or less robust mechanical assemblies that wear out faster in demanding environments. For rooftop units exposed to Texas heat or difficult indoor environments, like those with high levels of grease and moisture, those low-quality components can reduce effective system lifespan.

Decision makers are best served by considering expected service life, warranty coverage and replacement intervals based on the unique variables present in their facilities. For properties with particularly demanding conditions, it can make sense to invest in an HVAC system that costs more initially but can last several years longer before major repairs or full replacement is needed.

That extra longevity defers another capital project and minimizes the business downtime associated with large-scale replacements.

Energy Efficiency and Operating Costs

Energy use typically represents the largest portion of a commercial HVAC system’s total cost. Even a modest difference in efficiency rating can compound over thousands of operating hours each year. Systems with variable-speed compressors, energy recovery ventilation and advanced control logic use less electricity while providing better comfort.

Quantifying those factors is a key aspect of LCA. A unit that runs more efficiently throughout its lifespan will have the potential to surpass the ROI of a lower-priced model long before another replacement is required. For property managers balancing budgets, that efficiency translates directly into lower utility bills and improved sustainability metrics, which can be especially attractive to tenants who monitor their own energy use.

Maintenance and Downtime

Maintenance costs are easy to underestimate when comparing bids. Equipment that requires specialized parts, frequent filter changes or complex access for service quickly adds hidden costs. Downtime for major repairs can also disrupt building operations, tenant comfort or production schedules.

Lifecycle cost analysis should incorporate predicted maintenance frequency, labor costs and downtime exposure in its calculations. Systems designed for accessibility and predictive maintenance reduce both reactive service calls and the likelihood of costly breakdowns. The goal is to establish a predictable maintenance budget instead of dealing with surprise expenses every few years.

Return on Investment (ROI)

When installation cost, efficiency, maintenance requirements and lifespan are considered together, the cheapest option rarely delivers the best ROI.

A true lifecycle comparison often reveals that spending more up front can reduce total ownership cost by a significant margin. That perspective is especially important for organizations managing multiple facilities or budgeting capital improvements over several years.

Reliable equipment keeps costs predictable, improves tenant satisfaction and aligns with long-term energy goals.

Building for the Long Term

Commercial HVAC systems are infrastructure, not disposable assets. The difference between a system that lasts 10 years and one that performs reliably for 20 can reshape a facility’s financial outlook. Approaching HVAC replacement planning as a measurable investment strategy rather than a short-term expense can pay dividends down the line.

Why Air Balancing Directly Impacts Tenant Complaints and Lease Renewals

Tue, 19 Aug 2025 19:52:25 GMT

In Arlington and Fort Worth, dependable cooling is near the top of ‘must-have’ lists for commercial tenants. When airflow is off, spaces drift from setpoint, humidity creeps up, and small comfort gaps turn into tangible, potentially lease-ending tenant complaints.

Air balancing is not just a commissioning checkbox. It is a retention lever.

After Internet Outages, Air Imbalances May be the Biggest Management Emergency

Comfort issues can quickly escalate from nuisance calls into perceived management neglect. A warm corner office, a chronically cold conference room or a lobby that never stabilizes signals that the building isn’t being effectively managed.

Common Causes That Push Systems Out of Balance

Post-build-out changes that alter loads and diffuser placement without recalculating airflow or static pressure.
Aging or modified ductwork with leakage, crushed flex or unsealed takeoffs that starve downstream branches.
Equipment swaps that change fan curves or available external static without rebalancing terminals.
Controls drift in BAS, failed actuators or overrides that leave dampers in the wrong position.
Neglected maintenance like clogged filters or fouled coils that raise pressure drop and shift airflow distribution.

Diagnosing Imbalance Before It Escalates

Experienced, well-equipped commercial HVAC technicians have a variety of methods for identifying the source and scope of air balancing problems.

BAS trend review: Technicians check zone temperature, discharge air temp, damper command vs. position, fan status and runtime. As a first step, professionals look into zones that never satisfy, simultaneous heat/cool issues or dampers pegged near full open.
Static pressure mapping: This involves measuring total external static and key branch pressures to see whether the fan is within design and determine which trunks are starved or overfed.
Terminal and diffuser verification: Technicians use flow hoods and pitot readings to compare delivered CFM against design at VAV boxes, FPBs or constant-volume branches. They also confirm damper travel and actuator function.
Envelope and load checks: HVAC professionals pay close attention to space changes, like added occupants, equipment heat or solar gain shifts after a remodel.
Thermal and airflow visualization: Technicians use smoke pencils or thermal imaging to identify short-circuiting supply to return, stratification or diffuser throw that never reaches the occupied zone.

How Commercial HVAC Contractors Resolve Air Balancing Problems

The goal is to restore design intent with the least disruption while setting the system up for repeatable performance.

Restore Duct Integrity and Distribution

Our technicians seal leakage at joints, takeoffs and plenums to stop pressure loss that reduces airflow to distant branches.
We correct duct geometry by replacing crushed or overly long flex, removing sharp turns and resizing undersized runs that restrict flow.
Balancing dampers are added or adjusted at strategic points to restore even branch-to-branch distribution without overthrottling terminals.
Diffusers are repositioned or replaced to match the space function. This is done by selecting the proper throw and pattern to eliminate drafts and dead zones, especially in high ceilings or glass-heavy perimeters.

Recommission Terminals and Zones

We recalibrate VAV and FPB boxes, verifying K-factors, flow sensors and actuator ranges. Minimums are set to maintain ventilation and prevent humidity creep during part-load operation.
Control sequences are tightened by setting correct deadbands, time delays and reset logic for discharge air and static pressure.
Reheat strategies are balanced so coils only engage when airflow is correct, preventing cooling and reheat from operating against each other.
Ventilation delivery is verified to ensure outside-air strategies meet code without overventilating and raising latent load during summer.

Right-Size Fan Performance and Setpoints

Fan speed and VFD programming are adjusted to reach design static pressure without oversupplying near trunks. Static pressure reset is applied based on actual box demand rather than a fixed high setpoint.
Supply-air temperature reset is implemented to reduce diffuser drafts and improve part-load comfort while maintaining proper dehumidification.
Economizer logic is coordinated so free cooling does not create stratification or humidity drift during shoulder seasons.

Controls and BAS Optimization

Our team rebaselines the sensor network, replacing failed or drifted sensors and mapping each zone correctly so operators can trust the data.
Schedules and operating modes are standardized to match tenant hours, aligning occupancy, setback and purge cycles to prevent the common early-morning or late-afternoon comfort pain points.
Targeted monitoring points are added in critical trunks, like flow, pressure or temperature sensors that allow the BAS to detect subtle imbalance before it becomes noticeable to tenants.

Institutionalize Rebalancing Triggers

Making air balancing part of standard change management can be a good idea for properties that frequently receive comfort complaints from tenants. Having any tenant build-out, density change, major equipment swap or diffuser relocation triggers a targeted rebalance is a dependable way to reduce complaints.
Scheduling seasonal checks ahead of cooling season to confirm minimum airflows, static pressure reset and dehumidification performance may sound excessive, but if air balancing is a consistent problem for your building it could be a good idea.

Enhance Your Facility’s Comfort, Efficiency and Perception With Properly Balanced HVAC

A balanced system runs closer to design, lowers energy waste and reduces mechanical strain. Fewer hot/cold calls save your staff time and reduces vendor costs. More important, consistent comfort communicates professional stewardship of the property, which supports tenant retention without concessions.

Are the “Savings” From a Commercial Energy Audit Really Worth the Time and Cost?

Fri, 15 Aug 2025 19:41:16 GMT

Some HVAC companies market energy audits as a surefire way to lower your facility’s bills, enhance your reputation and attract high-quality tenants. What these audits actually accomplish is debatable, and largely dependent on the quality of the assessment. Many property managers have been handed reports full of vague findings that lack context and contain questionable ROI projections based on expansive (and expensive) improvement plans.

The reality is that a commercial energy audit only provides value when it’s approached strategically, timed correctly, benchmarked against comparable buildings and used to inform budget decisions before funds are allocated elsewhere.

Why Timing Makes the Difference

For most facilities, the best time to perform an audit is just before budget season in late summer or early fall. At that point, your HVAC systems have operated under maximum load for months, providing a clear picture of peak cooling demand and true operating efficiency.

Waiting until winter or early spring can hide problems like compressor cycling or duct leakage which only appear during high heat. By auditing during or immediately after the cooling season, you capture your building’s most energy-intensive period.

From a financial perspective, this timing also aligns audit findings with capital planning. Identifying inefficiencies before budget deadlines allows managers to prioritize system upgrades or recommissioning while funding is still flexible, rather than deferring fixes for another year.

What a Commercial HVAC Energy Audit Actually Evaluates

A meaningful audit goes far beyond utility-bill analysis. Technicians should review a variety of data points and site conditions to isolate HVAC inefficiencies that often go unnoticed during routine service:

Utility and operational benchmarking across the past 12 months, normalized for weather and occupancy trends.
System performance testing that measures supply and return air temperatures, static pressure and equipment runtime to detect losses in capacity or airflow.
Control and scheduling review to find outdated setpoints, overlapping heating and cooling or inefficient fan operation during unoccupied hours.
Mechanical inspection of coils, filters and dampers to uncover airflow restrictions or leakage that drive up energy use.
Assessing envelope and ventilation to evaluate how infiltration and insulation affect total HVAC load.

Each element ties back to quantifiable efficiency metrics that can be benchmarked against similar properties and past system baselines.

Benchmarking Against Peer Buildings

Energy audits are most useful when results are compared to other buildings of similar size, type and usage. Benchmarking data, such as Energy Use Intensity (EUI) and operational hours, helps determine whether high consumption is the result of equipment performance or external factors like occupancy and weather.

This comparison turns raw audit data into context. A facility that performs worse than portfolio peers may justify major capital upgrades, while a building already near the efficiency curve might focus on control optimization for existing equipment instead. Benchmarking also strengthens internal budget discussions, showing stakeholders that improvement priorities are based on objective, comparative data rather than assumptions.

Common HVAC Inefficiencies Audits Reveal

Even without a full retrofit, audits frequently uncover issues that waste measurable amounts of energy:

Simultaneous heating and cooling caused by conflicting control sequences.
Constant-speed fans or pumps that operate at full load even during partial demand.
Damaged or leaking ductwork that lowers delivered airflow.
Misconfigured economizers that introduce excessive outdoor air in humid conditions.
Sensors or thermostats that have drifted, sending false readings to the BAS.

Addressing these problems can cut consumption, improve comfort stability and prolong system lifespan, which are all meaningful goals that can influence tenant satisfaction and long-term operating budgets.

Turning Findings Into Budget Strategy

Prioritize high-ROI actions such as control sequence adjustments or rebalancing that require minimal cost.
Plan phased equipment replacements for underperforming systems with verifiable payback potential.
Document results and projected savings in budget proposals to support funding requests with evidence rather than estimates.
Track performance year over year to show whether implemented measures deliver the expected reduction in energy use.

The Hidden Risks of “All-In-One” Bundled Service Contracts for HVAC Maintenance

Wed, 13 Aug 2025 19:35:14 GMT

Most commercial HVAC installation projects in Arlington and Fort Worth come packaged with a maintenance plan promising convenience, predictable costs and long-term protection.

On paper, the concept makes sense: one HVAC contractor installs the system, maintains it and keeps it running efficiently over its lifespan. In practice, though, the quality of that agreement depends entirely on the contractor’s follow-through. When service visits are skipped, documentation is incomplete, or technicians rotate constantly, “bundled maintenance” can become more of a liability than an advantage.

Why Bundled Maintenance Became the Industry Standard

Commercial HVAC installation has gradually shifted toward bundled service agreements because contractors want to retain control of the equipment after installation. These contracts typically include startup, commissioning and the first year of scheduled maintenance to maintain warranty compliance.

After that, most roll into annual or multi-year renewals marketed as worry-free service with promises of regular inspections and performance checks without requiring any effort from the property manager.

The structure is sound when executed properly. But many property owners find that the convenience promised up front doesn’t always materialize once the system is in service.

Where Bundled Service Often Fails in Practice

Missed or delayed visits: Service intervals may be defined as quarterly or semiannual, but some contractors quietly push appointments back or combine multiple visits into one. Commercial contracts are usually auto-scheduled through the contractor’s dispatch system, yet overbooked calendars, staffing gaps or poor coordination often cause visits to slip.
Superficial maintenance: Some providers perform only cursory work, like checking filters and refrigerant levels, while neglecting deeper tasks such as airflow measurement, coil cleaning, control calibration or verification of static pressure.
Poor documentation: Many facility managers receive generic service reports that say little more than “system checked.” Without specific readings or task verification, it’s impossible to confirm whether maintenance was performed as agreed.
Reactive rather than preventive service: Instead of catching issues early, contractors let systems run until failures occur, then bill for repair work that a proper maintenance routine should have prevented.
Labor-intensive for managers: Inconsistent technician assignment creates headaches. When a new tech arrives to perform maintenance and doesn’t know the building layout, access points or system specifics, property staff are forced to waste time on hand-holding. A company that keeps thorough internal service records avoids this problem, saving management time and reducing disruption.
Warranty risk: Skipped maintenance and incomplete service logs can void manufacturer warranties, leaving owners with unexpected repair or replacement costs.

Together, these issues erode the core benefit of bundled service: predictability. Instead of simplified maintenance, the result is lost time, rising energy use and preventable mechanical wear.

How to Tell When a Bundled Contract Is Working Against You

Property managers often discover problems only after efficiency or comfort declines. Warning signs include:

No confirmation of service dates or missing follow-up reports.
Maintenance tasks frequently marked as “rescheduled.”
Comfort complaints or higher utility bills despite supposed regular service.
No clear maintenance record to support warranty claims.

If any of these are familiar, the bundled arrangement may be reducing ROI instead of protecting it.

What Reliable Bundled Maintenance Should Look Like

When handled correctly, a bundled contract can still deliver meaningful value. A trustworthy provider will typically offer:

Consistent scheduling and verification: Visits occur when promised, and reports include specific measurements.
Comprehensive scope: Technicians perform full inspections, like testing airflow, cleaning coils, verifying control function and adjusting static pressure.
Transparent reporting: The company provides detailed records that let managers track energy performance and maintenance history.
Continuity of service: Providers with strong internal documentation systems maintain detailed service histories, access notes and system data so every new or returning technician starts fully informed.
Proactive recommendations: Findings are communicated in business terms, including energy impact, comfort metrics and capital planning relevance, rather than vague “suggested upgrades.”

Should You Bundle Maintenance After HVAC System Replacement in Arlington or Fort Worth?

Bundled maintenance is not inherently bad; it’s simply overpromised in many cases. For property owners, it offers value when the contract is transparent, the scope is verifiable and the contractor demonstrates accountability. It works best when:

The provider has dedicated commercial service infrastructure and trained technicians.
The contract clearly defines visit frequency, task lists and documentation standards.
The same company that installs the system remains responsible for its ongoing care.

When those elements are missing, keeping installation and maintenance separate can improve accountability and make it easier to replace underperforming vendors.

At Tom’s Commercial, our bundled service contracts include documented inspections, detailed internal documentation and verified performance tracking. Our goal is for property managers to spend less time managing service visits and more time running their facilities.

How Your Building’s HVAC System Compensates for Rapid Changes in Occupancy

srobertstoms.rev77@gmail.com (Steve Roberts) — Fri, 18 Jul 2025 18:05:53 GMT

In commercial buildings, occupancy can change dramatically over just a few minutes; employees clocking in at 8 a.m. or out at 5 p.m., students flooding out of classrooms at 2:30 p.m. or a congregation filling pews for Sunday service at 8:30 a.m. Compensating for rapid shifts in occupancy is something commercial HVAC systems have always needed to handle.

But what does your HVAC system actually do when these shifts happen? Does it automatically detect people coming and going, or does it just respond to changes in temperature or air quality?

How a Typical HVAC System Responds

Most standard commercial HVAC systems don’t directly sense people. They react to the side effects of occupancy:

More people mean more body heat, rising CO₂ levels and higher humidity.
Fewer people mean less heat load, lower CO₂ and reduced need for ventilation.

For example, when a crowded office empties at 5 p.m., the space gradually cools, CO₂ drops and the system reduces cooling output. These are simply reactive adjustments based on temperature or air quality sensor readings, not because it “knows” people left.

This approach works for many commercial applications, but it can lag behind actual occupancy patterns, especially in buildings with unpredictable schedules. In other words, there’s often a stuffy, warm period at the start of the work or school day and an uncomfortably chilly period for anyone who stays late.

How Advanced Systems with Occupancy Sensors or BAS Respond

Modern HVAC setups often include occupancy sensors, demand-controlled ventilation (DCV) or building automation systems (BAS) to manage these shifts more proactively.

Occupancy sensors : Detect motion or presence in specific zones, allowing the system to reduce airflow or adjust temperature when rooms are vacant.
DCV systems : Use CO₂ sensors to adjust the volume of fresh outside air, ensuring optimal ventilation based on how many people are in the space.
BAS platforms : Let facility managers program detailed schedules, automate temperature setpoints and coordinate multiple systems across the building.

With these tools, the system can anticipate occupancy changes. For example, it might pre-cool a church sanctuary before Sunday services or reduce ventilation to empty classrooms after dismissal, improving both comfort and energy efficiency. It also makes these spaces more tolerable for any occupant who may come in early or stay late.

Common Examples in Commercial Spaces

Office buildings : Peak occupancy during the workday, followed by an evening slowdown. Modern systems may also adjust for lower activity on Fridays or hybrid work schedules.
Schools : Heavy daytime use with near-empty buildings in the evening and weekends. Special events like assemblies or sports games create sharp but predictable spikes.
Retail stores : Busy afternoons and weekends, quiet mornings and overnight shutdowns. HVAC systems can be zoned to shut down nonessential areas after closing.
Churches or houses of worship : Large crowds during scheduled services, with long periods of minimal use the rest of the week. Smart systems can ramp up airflow or cooling before congregants arrive then scale back after services.

Mechanical Considerations and Adjustments

Behind the scenes, the HVAC system uses several mechanical strategies to balance comfort and efficiency as occupancy changes:

Variable air volume (VAV) systems : Adjusts airflow to match the needs of each zone, reducing or increasing supply as demand shifts.
Packaged rooftop units (RTUs) : Stage compressors, fans or heating elements run at partial capacity when loads are light.
Demand-controlled ventilation (DCV) : Modulates outside air dampers based on CO₂ levels, ensuring fresh air without overventilating empty spaces.

Without these mechanical adaptations, buildings risk overcooling, poor air quality or unnecessary energy costs.

Why Many Commercial Facilities Benefit From More Than Just Reactive Adjustments

An HVAC system that fails to properly adjust to occupancy patterns can contribute to:

Hot spots or stuffy rooms during large gatherings.
Energy waste from overventilating or overcooling empty spaces.
Unhappy occupants due to inconsistent comfort.

Optimizing an HVAC system to handle occupancy shifts keeps buildings efficient, comfortable and aligned with energy-saving goals, lowering utility bills and extending equipment life.

The Role of Air Balancing in Multi-Zone Commercial HVAC Systems

srobertstoms.rev77@gmail.com (Steve Roberts) — Fri, 18 Jul 2025 17:44:04 GMT

Air balancing is the process of adjusting airflow throughout a building so that each zone receives the right amount of heated or cooled air. Getting air balancing right requires:

Measuring airflow at supply and return registers.
Adjusting dampers, fan speeds or variable air volume (VAV) boxes.
Ensuring that the system delivers designed airflow rates to each space based on its size, use and occupancy.

In short, air balancing is about fine-tuning the system so no area is starved for air or overloaded.

The Common Causes of Imbalances in a Once Properly Balanced Building

Air balancing in commercial spaces, particularly offices, retail spaces or any multi-tenant facility where layouts are regularly rearranged, can be a frequent challenge. Building managers don’t always think about the effects on air balancing when walls are removed, room layouts are drastically altered or an open space is converted into offices.

There are also mechanical issues that can crop up unexpectedly. Ducts can leak, dampers can fail or the equipment that controls fan speed, like belts and fan motors, can degrade over time. Problems can also arise from simple issues that can be easily addressed with commercial HVAC maintenance , such as clogged filters or coil blockages.

Why Multi-Zone Systems Make It More Complex

In a single-zone system, you have one thermostat and one general air distribution path. In multi-zone setups, which are far more common in commercial applications, things get more complicated.

Offices have conference rooms, open workspaces, private offices and server rooms, all needing different airflow. Changes to layouts are more common in multi-tenant office spaces compared to other commercial facilities, making air balancing challenges more common in these buildings.
Schools include classrooms, gyms, cafeterias and administrative offices, with widely varying demands.
Medical buildings have patient rooms, labs, waiting areas and surgical spaces, where precise airflow and pressurization are critical.

Without proper balancing, some zones will constantly overheat or overcool, forcing occupants to adjust thermostats regularly or call in complaints. In addition to causing tenant comfort and efficiency problems, air balancing issues can also put HVAC equipment at risk. Poorly balanced systems experience increased strain, accelerating wear and reducing longevity.

How Air Balancing Improves Comfort and Efficiency

Comfort

Balanced airflow ensures all areas stay within temperature setpoints, avoiding hot and cold spots that frustrate tenants or employees. It also helps maintain consistent humidity levels and better indoor air quality, creating a more pleasant and healthy environment.

Efficiency

When airflow is correctly distributed, the HVAC system doesn’t have to work harder to compensate for imbalances. This reduces energy use, minimizes equipment wear and lowers operating costs. Proper air balancing also extends the lifespan of major components like fans, motors and compressors.

Signs Your Building Needs Air Balancing

Persistent temperature differences between rooms or zones.
Tenant or employee complaints about drafts, stuffiness or inconsistent comfort.
Excessive fan noise or air rushing at certain vents.
High energy bills despite no obvious system failures.

These are all clues that airflow needs to be measured and recalibrated.

How Often Should Air Balancing Be Checked?

While air balancing is typically done after initial installation, it’s a good idea to reassess it after major building or layout changes, particularly if you’re receiving multiple tenant complaints about temperature control consistency. Tenant turnover, layout modifications or mechanical wear can all throw off balance over time, making periodic checks during maintenance an important part of long-term system upkeep.

What’s Involved in an Air Balancing Service?

Measuring airflow at supply and return registers across all zones.
Checking fan speeds, damper settings and VAV box operation.
Adjusting dampers or controls to match design airflow specs.
Testing static pressure to confirm the system is operating efficiently.
Documenting results and providing recommendations for ongoing performance.

It’s a detailed process, but one that pays off in comfort, efficiency and fewer service calls.

Why One-Size-Fits-All HVAC Maintenance Doesn’t Work for Every Building

srobertstoms.rev77@gmail.com (Steve Roberts) — Fri, 18 Jul 2025 17:25:42 GMT

One of the more common misconceptions regarding commercial HVAC is that there’s little difference between residential and commercial maintenance.

You swap the filters every few months and call a technician to come out and check the refrigerant levels and run some diagnostics every spring and fall.

Unfortunately, a low-touch, residential-style approach to maintenance rarely works for most commercial HVAC setups. Neglecting regular diagnostics, cleaning and service can lead to costly repairs, loss of warranty coverage, efficiency losses and even premature system failure.

Different Buildings, Different HVAC Demands

Facility size, layout, square footage, ceiling heights, number of entrances and exits, number of windows, sun exposure and other variables affect climate control and indoor air quality demands. The diversity of commercial structures means there’s no single standard maintenance approach that provides optimal upkeep.

Warehouses often have wide-open spaces with fewer zones and minimal temperature control variation, but their rooftop units (RTUs) may run nearly nonstop in summer to keep employees, equipment and stored goods at safe temperatures.
Offices experience high daytime occupancy, meaning heavier cooling during business hours and reduced demand after hours.
Schools have sharp daytime peaks and evening downtime but need consistent ventilation for dozens of separately zoned classrooms.
Many healthcare facilities run 24/7, with critical air handling and pressurization needs to protect patient health.

These are just a handful of examples. Nearly every industry has its own climate control quirks and performance demands. These differences directly affect how often equipment runs, how quickly components wear and what maintenance actually preserves system performance.

Ventilation and Filtration Needs Vary by Use

An office lobby and a hospital operating room don’t have the same air quality standards and their HVAC maintenance should reflect that.

Healthcare and lab environments require frequent filter changes, coil cleanings and air handler checks to meet air purity requirements.
Manufacturing or light industrial spaces often face dust and particulate buildup that requires more frequent filter changes and coil cleanings to keep equipment running efficiently.
Offices or retail spaces can often go longer between some tasks but still need regular inspections to avoid unnoticed failures.

A generic plan that ignores these differences risks both equipment health and building safety.

Environmental Conditions Add Unique Stress

One variable property owners often overlook when thinking about HVAC performance and maintenance is how building use impacts indoor air quality.

Industrial or manufacturing facilities may have dust, debris or fumes that clog filters and coat coils faster than expected.
Gyms, pools and natatoriums struggle with high humidity that can corrode components if not actively managed.
Retail spaces experience fluctuating occupancy and heat loads, especially around seasonal sales or holidays.

A copy-and-paste maintenance approach won’t account for these challenges, and without tailored attention, small issues can become big problems.

Compliance and Warranty Requirements Matter

Not all commercial HVAC equipment has the same maintenance requirements, and following the manufacturer’s recommended servicing is often essential to keep warranties valid.

· High-efficiency systems typically require regular inspections, filter changes, coil cleanings and performance checks as outlined in the warranty terms.

· Specialized components like variable-speed motors, economizers or demand-controlled ventilation systems may have specific upkeep requirements.

Skipping or delaying these tasks can void warranty coverage, leaving building owners on the hook for expensive repairs or replacements. A generic maintenance plan may overlook these critical steps, putting your investment at risk.

Finding the Ideal Maintenance Balance for Your HVAC Systems

Too little maintenance means missed warning signs, efficiency losses and surprise breakdowns. But too much maintenance, such as replacing filters or inspecting components more frequently than needed, wastes time and money.

The goal is to match the right level of service to the building’s actual needs, balancing cost with long-term performance.

Let Our Commercial HVAC Professionals Build a Maintenance Plan Around Your Property’s Actual Needs

At Tom’s Commercial, we don’t believe in handing clients a standard service package and calling it a day. Instead, we:

Assess your building type, occupancy patterns and equipment setup.
Recommend a maintenance schedule tailored to your system’s usage, environment and goals.
Help you meet energy code requirements, preserve warranty coverage and extend system lifespan.
Provide reliable follow-through, not just a maintenance promise on paper.

Most commercial HVAC companies will include maintenance with a large system replacement project . A common problem with this approach is a lack of follow-through. If your HVAC provider promised quarterly maintenance visits but only showed up twice last year, you may want to call someone else.

How Economizers Use Outside Air to Lower Cooling Costs

srobertstoms.rev77@gmail.com (Steve Roberts) — Fri, 18 Jul 2025 17:15:18 GMT

Facility managers and commercial property owners in North Texas have to manage a lot of variables to control operating costs. Climate control is usually one of the largest expenditures in the expense column. Economizers can be an efficiency-enhancing HVAC addition for many facilities, but they’re not an ideal solution for every application.

An economizer is included in most modern RTUs or can be added to pull in cool outside air when weather allows, reducing the need for mechanical cooling. Instead of always relying on compressors and chillers, the system lets nature do part of the work, saving energy and lowering utility bills.

How Economizers Work

Economizers monitor outdoor air conditions to decide when it’s efficient to bring that air indoors for cooling. There are two main types:

Dry bulb economizers look only at the outdoor air temperature.
Enthalpy (wet bulb) economizers check both temperature and humidity, which is especially important in Arlington and the greater Dallas–Fort Worth area.

When outdoor air is cool and dry enough, the economizer opens dampers to bring in fresh air and reduce the load on your air conditioning system. Most new or replacement RTUs already include economizers, as many are designed to meet current energy codes and efficiency standards right out of the box.

Does My Building’s Current HVAC System Have an Economizer?

Systems installed within the past several years likely already include an economizer, but those managing outdated equipment may want to talk to a commercial HVAC professional about whether retrofitting is possible or if it’s time to consider a full system replacement. Adding an economizer can be a worthwhile upgrade if the existing equipment is compatible.

If you’re not sure whether your system has an economizer, check your rooftop unit or HVAC equipment for external dampers and look for an economizer controller or module in the system’s control panel. Maintenance teams can also review equipment specifications or installation records. When in doubt, an HVAC professional can inspect the system to confirm whether an economizer is installed and working properly.

When They Make Sense in North Texas

While DFW summers are famously hot and humid, there are still plenty of times when outside air can help cool a building. Economizers work best:

During spring and fall, when days are mild and humidity is lower.
On cool mornings or evenings, when the outside air is significantly cooler than indoor spaces.

One of the best things about economizers is that they work automatically to deliver energy savings without extra effort from building occupants. When outdoor conditions are right, the system’s controls switch over on their own to use outside air to help meet the thermostat’s temperature settings.

There’s no need for facility managers or tenants to manually activate the economizer. Once installed and set up properly, it’s a hassle-free way to capture efficiency benefits.

Best-Fit Applications

Economizers are a smart choice for many commercial spaces, particularly when the building has large, open zones and a predictable occupancy pattern. Good examples include:

Warehouses with open layouts and large air volumes.
Office buildings with shared spaces and fewer individual zones.
Manufacturing facilities where internal heat gains are high.
Retail stores with open floorplans.

These spaces can benefit from “free cooling” without the complications that come with many small, separate zones.

Where Economizers Offer Limited Benefits

Economizers don’t offer the same value in every building. In some applications, the system may rarely find conditions where using outside air makes sense, or facility managers may intentionally limit or disable economizer use to meet specialized needs. Examples include:

Schools with many separate zones , where pulling in outdoor air could cause uneven temperatures between classrooms and make it harder to manage comfort.
Medical facilities , where strict air quality, filtration and pressurization standards limit or override economizer operation to protect patient environments.
Data centers , where precise humidity control and environmental stability matter more than potential cooling savings.
Buildings near heavy outdoor pollution , where drawing in untreated air poses indoor air quality concerns.

In these settings, the economizer hardware is typically present but operates under tighter controls and may rarely activate. When the potential risks outweigh the energy savings, economizers may be purposefully deactivated.

Would Economizers Work Well in Your Arlington or DFW Facility?

Facility managers and building owners interested in improving climate control efficiency without sacrificing performance should ask the commercial HVAC team at Tom’s Commercial about economizer installation or calibration.

Proper sizing, installation and maintenance are key to ensuring the system works as intended, and that the energy savings actually materialize. Call us at 817-857-7400 for more information or to request repair or maintenance to keep your HVAC system running properly.

How Dirty HVAC Coils Quietly Destroy Efficiency and Air Quality

srobertstoms.rev77@gmail.com (Steve Roberts) — Fri, 27 Jun 2025 21:48:40 GMT

Commercial HVAC units are usually tucked away, often on rooftops, so their appearance isn’t usually top of mind. Although this isn’t necessarily a bad thing, it often means facility managers and owners don’t realize how dirty their evaporator coils are.

When they’re neglected, dirty coils can seriously affect comfort, air quality and operating costs. Dirty coils are frequently found in commercial environments where units are exposed to the elements and don’t receive routine maintenance.

Unlike sudden mechanical breakdowns, coil contamination causes gradual performance loss that can be hard to detect until your tenants, customers or employees begin complaining about poor AC performance.

The Role of Coils in HVAC System Performance

Your HVAC system uses two types of coils to control indoor temperature.

Evaporator coils , located indoors, absorb heat from the air during the cooling process.
Condenser coils , typically found in outdoor units, release that heat back into the environment.

When either coil becomes dirty or coated with debris and grime, the heat transfer process becomes less efficient. That reduced efficiency forces the system to run longer cycles to reach set temperatures, increasing wear on components and driving up energy bills.

Why Coil Contamination Happens

Commercial rooftop units (RTUs) operate in harsh conditions. Windblown dust, soot, pollen and industrial particulates collect on condenser coils throughout the year. Condenser coils are also exposed to leaves, bird droppings and even grease vapors in urban areas or near restaurants.

Indoors, evaporator coils can accumulate dust and moisture over time, especially when filters aren’t changed regularly or when airflow is restricted.

Poor ventilation design or overcrowded mechanical rooms can make the problem worse. In buildings with high occupancy or equipment-generated heat, dirty coils can quickly throw off the system’s load balance.

Symptoms of Dirty Coils

Unlike a unit that won’t start or a leaking refrigerant line, dirty coils don’t always announce themselves with an obvious problem. Instead, performance declines gradually, making it harder to pinpoint the cause. Some warning signs include:

Rising energy usage despite no changes in building occupancy
Weak airflow at supply vents
Unusual or persistently high indoor humidity
Zones that consistently feel too warm or too cold
Short cycling or long recovery times after setbacks

Left unaddressed, dirty coils can eventually cause the system to overheat, ice up or trip safety controls, leading to expensive repairs and downtime.

Air Quality and Occupant Health Risks

Evaporator coils exposed to high humidity and dust are ideal environments for bacterial buildup and other organic contaminants. Once embedded in the coil fins, these pollutants can be hard to remove without proper cleaning. As air continues to move across the coils, contaminants may recirculate through the duct system and throughout the building.

Poor indoor air quality can trigger complaints from occupants, especially in schools, office buildings or medical facilities where clean air is essential. If filters are undersized or overdue for replacement, the risk of contaminant recirculation increases dramatically.

How Often Should Coils Be Cleaned?

At a minimum, condenser coils should be inspected and cleaned at least once per year, preferably before peak cooling season.
Evaporator coils may require cleaning every one to two years, depending on filter quality and indoor conditions.
Facilities in dusty or industrial areas may need more frequent service.

Preventive cleaning helps restore proper heat exchange, lowers static pressure in the system and reduces the likelihood of compressor failure.

Can Coil Issues Be Fixed Without Replacing Equipment?

In many cases, yes. Coil cleaning can restore lost efficiency and postpone the need for major repairs or replacement . A trained HVAC technician will inspect the coils for buildup, corrosion and damage, then use chemical cleaners or pressurized rinsing to remove contaminants without damaging the fins. If coil cleaning reveals deeper issues, like refrigerant leaks or airflow problems, those can be addressed at the same time.

Coil Condition is Important for Commercial Properties in Arlington

Dirty HVAC coils might not cause immediate shutdowns, but they’re one of the leading causes of efficiency loss in commercial buildings.

Your HVAC maintenance provider should check your coils during visits and clean them when necessary. Unfortunately, many commercial HVAC companies fail to adhere to maintenance contracts, showing up only once or twice a year when they initially agreed to quarterly visits.

If your maintenance provider is neglecting your property’s systems, and you’re concerned about the efficiency and performance of your units, call Tom’s Commercial. We can provide a full HVAC performance evaluation, including coil inspections, refrigerant checks and airflow balancing.

If your building hasn’t had a coil cleaning in the last 12 months, now is the time to get on a preventive maintenance schedule. Call 817-857-7400 to schedule your service .

What Are ASHRAE Standards and Do Property Owners and Facility Managers Need to Worry About Them?

srobertstoms.rev77@gmail.com (Steve Roberts) — Mon, 23 Jun 2025 21:34:04 GMT

The American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) sets widely recognized benchmarks for HVAC system design, ventilation, indoor air quality and energy performance. In most cases, facility managers don’t need to worry about ASHRAE standards. Most of the benchmarks are related to HVAC equipment, and manufacturers don’t typically manufacture commercial HVAC equipment that doesn’t meet current ASHRAE standards.

Some guidelines do influence system design, particularly ductwork and indoor air quality, but for the most part these are things for your system installer to worry about.

What Are ASHRAE Standards and Are They Mandatory?

ASHRAE publishes a wide range of technical standards, but two of the most relevant to commercial property owners and facility managers are:

ASHRAE Standard 62.1 , which covers ventilation system design and acceptable indoor air quality in commercial and institutional buildings
ASHRAE Standard 90.1 , which covers minimum energy efficiency requirements for HVAC systems and components

Texas doesn’t have a statewide mandate requiring HVAC systems to meet ASHRAE specifications, but many local jurisdictions, including Arlington, base their building codes on the International Mechanical Code (IMC) and International Energy Conservation Code (IECC), which incorporate parts of these ASHRAE standards.

Arlington has adopted the 2021 addition of the International Building Code (IBC) and IECC. The IECC incorporated ASHRAE 90.1 standards, so technically, for new builds to be compliant with local energy code, they must meet the relevant ASHRAE standards.

However, most existing systems are grandfathered in, and property owners won’t be required to retrofit or replace anything unless they invest in a major system overhaul that triggers new permit reviews.

You Don’t Need to Worry About Having a Non-Compliant System Installed

Any new commercial rooftop unit, chiller or split system available today is going to comply with ASHRAE 90.1 in terms of energy performance. Most clients don’t need to worry about meeting ASHRAE standards during HVAC replacement . The product specs already cover it.

What HVAC Contractors Actually Do to Align With ASHRAE

While the equipment itself checks the compliance boxes, HVAC companies still play a role in aligning your system with ASHRAE’s operational goals:

System design and duct layout using airflow best practices based on occupancy
Proper sensor placement and zoning, especially in larger or multi-use buildings
Fresh air intake management, including CO₂ sensor setup where applicable
Commissioning and documentation when required for inspections or certifications

Tom’s Commercial follows best practices that adhere to ASHRAE 62.1 and ASHRAE 55 guidelines as part of our system planning process, particularly when designing for comfort across zones with different loads, such as schools, offices or churches.

Do You Need to Retrofit Older Systems to Comply?

In most cases, no. Older HVAC systems are not required to meet modern ASHRAE standards unless they’re being replaced or extensively modified. However, that doesn’t mean your old system is running efficiently.

If your building has persistent comfort issues or your energy usage is higher than it should be, a professional evaluation can identify whether small upgrades, like rebalancing ductwork or adjusting zoning, could bring your system closer to current performance standards.

Can Existing Systems Be Brought Up to Standard?

In many cases, yes, but the solution depends on the specific gap. Tom’s Commercial can evaluate your HVAC system and recommend adjustments, upgrades or retrofits that are appropriate for your facility’s layout and occupancy.

Some improvements, like adjusting ventilation schedules or adding CO₂ monitoring, are relatively minor. Others, like improving duct insulation or rebalancing zones, may require more planning and coordination, especially in schools, churches or older municipal buildings with high variation in occupancy and room sizes.

The goal of retrofitting and upgrading isn’t always to hit every ASHRAE number perfectly. It’s to bring your system in line with best practices that reduce energy waste, extend equipment life, and support health and comfort across your property.

How Sensor Placement Affects Commercial HVAC Accuracy

srobertstoms.rev77@gmail.com (Steve Roberts) — Fri, 20 Jun 2025 21:25:22 GMT

Thermostats and temperature sensors act as the eyes and ears of your system. If they’re installed in the wrong spots, your building could end up fighting itself to maintain comfort. Zoned systems, especially in offices, schools and multi-use facilities, are more likely to experience temperature control issues due to poor sensor placement.

Why Sensor Placement Matters

HVAC sensors are what your system uses to determine when to run, how long to run and how much heating or cooling to deliver to each zone. If a sensor is placed near a drafty window, under direct sunlight, too close to a supply vent or in a low-traffic corner, it may give a skewed reading that triggers unnecessary system activity and causes parts of the building to become too warm or too cold.

In addition to poor climate control and comfort complaints from tenants or employees, sensor placement issues can lead to higher energy bills and accelerate wear on motors and other HVAC components.

Sensor Placement and Zoning

Zoning is a necessary feature in most commercial HVAC applications. Whether it’s an office, school, medical facility or church, there’s usually a need for different rooms or areas to have independent temperature control based on use, occupancy and exposure. Proper sensor placement is critical in commercial systems because:

A sensor in one room may control airflow for multiple rooms or a whole hallway.
A poorly placed sensor can cause a zone to overcool or underheat.
If sensors are clustered or installed inconsistently, one zone may dominate the system’s behavior.

Ideally, sensors should be placed in representative, high-traffic areas that are not near exterior doors, windows or heat-generating equipment. They should reflect the average conditions of the zone they control, not the extremes.

Common Sensor Placement Mistakes

Sensors installed too close to vents or returns, where airflow disrupts readings.
Thermostats placed in unoccupied rooms that don’t reflect real-world use.
Improper zoning layouts that assign too many varied spaces to a single sensor.
Multiple sensors in one zone without clear coordination or hierarchy.

These problems are common in older systems or buildings that were renovated without updating HVAC zones or controls.

What Are the Signs of Misplaced Sensors?

If tenants, employees or customers are complaining about any of the following issues in your building, sensor placement could be part of the problem:

Some zones always feel stuffy or overcooled.
The system runs more often than expected.
Occupants regularly adjust thermostats without resolving the issue.
One part of the building seems to dictate system behavior for others.
Your building management system (BMS) shows inconsistent temperature swings in certain areas.

Even high-efficiency equipment can struggle when it’s getting bad data from sensors.

Can Sensor Placement Be Adjusted or Corrected?

Yes, and in many cases, the fix is simpler and more affordable than you might expect. A technician can:

Evaluate current sensor locations and adjust or relocate them.
Calibrate sensors to account for known ambient distortions.
Add more sensors for better zone coverage.
Reprogram thermostats or BMS zones to better match room usage.

In some scenarios, more invasive changes may be recommended. For example, if zones are poorly defined or ductwork doesn’t match the intended zone layout, you might need to install additional dampers or reroute airflow. However, these types of modifications are usually reserved for systems with chronic airflow imbalance or major layout mismatches.

Sensor Adjustments May Be an Easy and Affordable Solution for Inconsistent Zone Control

If your building has persistent hot/cold complaints, erratic system behavior or zones that never seem to stabilize, it may not be your equipment’s fault. It might just be your sensors telling the system the wrong story.

Improper sensor placement or broken sensors are not good problems to have, but sensor issues can be more affordably fixed than failing HVAC units or serious ductwork problems. Adjusting sensor placement or adding more is a fairly easy process in most circumstances, and it can potentially lead to dramatic improvements.

The HVAC professionals at Tom’s Commercial can assess your existing sensor layout, identify misalignment with current zone usage and recommend targeted fixes that reduce strain on your system while improving comfort.

Why Commercial HVAC Units Trip Breakers in the Summer and What to Do About It

srobertstoms.rev77@gmail.com (Steve Roberts) — Wed, 18 Jun 2025 20:55:43 GMT

HVAC systems work much harder during summers in North Texas. For commercial-grade systems that carry a large load, that translates to a significant spike in current draw.

It’s unsurprising that one of the most common calls commercial HVAC contractors receive in the summer is about units repeatedly tripping breakers. These issues are often not indicative of a problem with service panels or breakers, but rather a symptom of mechanical strain, airflow problems or neglected maintenance .

Why Breakers Trip

Commercial HVAC systems draw a lot of power, especially during startup. A circuit breaker is designed to protect your system by cutting off power when current exceeds safe limits. If the unit’s normal operation crosses that threshold, the breaker trips to prevent overheating, fire or equipment damage.

A single breaker trip isn’t always cause for concern. But if your unit trips repeatedly, especially during hot afternoons or under high load, there’s likely an underlying issue that needs attention.

Common Reasons Commercial HVAC Units Trip Breakers in Summer

Dirty Coils or Air Filters: Restricted airflow is one of the most frequent culprits. When filters are clogged or coils are coated with dirt and debris, the system has to work harder to move air. This puts strain on the compressor and blower motor, which may draw more current than the breaker is rated for.
Failing Compressor: Summer is peak workload season for HVAC compressors in Arlington. If a compressor is failing or seizing up under load, it may draw excess amperage during startup. That surge can trip the breaker, especially if the system is short cycling or running continuously due to poor airflow or improper sizing.
Electrical Problems: Loose connections, aging contactors or damaged wiring can increase resistance and create heat. That added resistance can cause current spikes that trip the breaker even if the equipment itself is functioning normally. Summer heat can also exacerbate minor electrical faults.
Low Refrigerant: In addition to affecting cooling performance, low refrigerant levels cause the compressor to run under stress. This can trigger an overcurrent situation during startup or while trying to keep up with demand. Many commercial buildings won’t notice a refrigerant issue until the load increases during the summer.
Oversized Units or Poorly Balanced Loads: In some commercial spaces, especially those with recent renovations or added zones, the HVAC system may not be matched to the actual cooling load. If too many zones are relying on a single rooftop unit, the equipment may run continuously, short cycle or start and stop erratically, all of which can lead to breaker trips.

What to Do When Breakers Trip

If your HVAC system trips a breaker more than once in a brief period, don’t just reset it and move on, or assume it will resolve when temperatures drop. Repeated tripping is a warning sign that your system is under unusual strain. Continuing to operate it without inspection can lead to compressor failure or even damage to your electrical system.

A licensed commercial HVAC technician can:

Inspect the unit’s startup and operating amperage
Clean coils, check filter condition and restore proper airflow
Test refrigerant levels and compressor performance
Identify failing components before they lead to full system failure
Coordinate with electricians if a panel or breaker issue is suspected

In many cases, these issues can be addressed with minor repairs or maintenance. If the system is nearing the end of its service life, your technician may also recommend a phased replacement plan or zone rebalancing to reduce load.

Preventative Steps for Facility Managers

If you want to reduce the risk of mid-summer shutdowns, seasonal maintenance is key . A summer check-up before peak heat hits can catch many of the conditions that lead to breaker trips. This is especially important in systems that serve multiple zones or large square footage.

You should hold your commercial HVAC service provider accountable by confirming they are performing all the necessary maintenance steps to prevent current spikes. These tasks include:

Changing filters on a planned schedule
Cleaning coils on a regular schedule
Calibrating thermostats and ensuring programming matches occupancy and usage patterns
Checking units during peak load periods for signs of stress

Even a well-installed unit can fail prematurely if airflow, maintenance or load balancing aren’t addressed. The team at Tom’s Commercial can help with diagnostics and maintenance to ensure your tripped breakers aren’t just one symptom of more serious HVAC issues.

How Rooftop HVAC Units Improve Service Access and Security for Commercial Buildings

srobertstoms.rev77@gmail.com (Steve Roberts) — Wed, 14 May 2025 22:32:59 GMT

In the Dallas–Fort Worth area, rooftop HVAC units are a common sight on schools, warehouses, churches and single-story commercial buildings, and not just because they save space. For many properties, placing HVAC systems on the roof offers practical advantages that can help reduce maintenance disruptions, prevent damage and improve overall system protection.

Why Rooftop Units Are Common in Commercial HVAC

Rooftop HVAC units, often referred to as RTUs, are designed specifically for large open spaces and low-rise buildings. They’re self-contained systems installed on flat roofs and connected to internal ductwork that’s routed downward into ceiling plenums or other open spaces. These units are popular because they:

Save ground space, keeping mechanical equipment out of the way
Simplify zoning and air distribution in wide, open layouts
Centralize equipment, making service and monitoring easier

There are some differences in vertical airflow design for ductwork connected to RTUs, which is why many property owners replace a roof RTU with another roof unit or a ground unit with another ground unit. Reworking ductwork is an option for property owners who want to switch from a ground unit to an RTU, but it can increase project costs.

Beyond those core performance advantages, rooftop units also offer clear benefits for service access and equipment security.

Easier Access for Technicians

When a technician needs to service or inspect your HVAC system, rooftop access keeps the work isolated from your day-to-day operations. Unlike ground-mounted units, RTUs don’t require a tech to walk through hallways or tenant spaces to access key components.

The presence of HVAC techs on the grounds isn’t a major issue for most commercial customers, but it can be for some. If keeping service techs out of sensitive areas and away from patients, students, workers or clients is important for security or privacy reasons, rooftop units can be beneficial.

Rooftop units can also enhance efficiency from a maintenance and repair standpoint for multi-unit or multi-building properties. All the units are grouped together in an isolated area, allowing techs to get work done quickly and efficiently.

Reduced Risk of Vandalism and Theft

Ground-mounted HVAC units are vulnerable to vandalism, copper theft and other forms of tampering, especially in locations with minimal security or long off-hours. Rooftop placement significantly reduces these risks by limiting visibility and access.

In many commercial buildings, roof access is locked or monitored, making it more difficult for anyone to reach the equipment without authorization. This added security is particularly valuable for:

Schools, churches and other buildings that may not be occupied for days at a time
Warehouses with minimal overnight staffing
Standalone business structures

Lower Risk of Accidental Damage

Beyond intentional tampering, rooftop placement helps protect HVAC systems from everyday hazards. Ground-level units are regularly exposed to lawn equipment, delivery trucks and wind-tossed debris.

On the roof, HVAC systems are better shielded from routine activity around your property, meaning less risk of damage from errant drivers or inattentive landscapers.

Why Some Buildings Can’t Support Rooftop Units

Not every building is built for rooftop HVAC placement. The biggest limitation is structural: flat commercial roofs need to be strong enough to support the weight and vibration of the unit over time. Roof design, material condition and load-bearing capacity all factor into rooftop mounting feasibility.

Ductwork logistics for multi-story buildings, lack of roof access or safe service routes, and the cost and complexity of retrofitting older buildings are all potential issues that could limit your installation options.

HVAC Security Solutions for Ground-Level Units

Just because your unit needs to be installed on the ground doesn’t mean it can’t be protected. Ground-level HVAC systems can be adequately secured to deter theft, vandalism and accidental damage. Some of the common ground-level HVAC protection solutions include:

Installing metal locking cages around outdoor units to deter tampering
Adding motion-sensor lighting and surveillance cameras in vulnerable areas
Creating fenced mechanical enclosures with limited staff access

The team at Tom’s Commercial, Inc. is sensitive to the safety and security concerns of businesses in Arlington and the surrounding areas. System replacements or repairs due to vandalism or accidental damage are an expensive and preventable drain on your resources. That’s why we’re always happy to evaluate your situation and recommend the right combination of security features to maximize safety without compromising service access.

Designing a Commercial HVAC System That Meets the Needs of a Mixed-Use Building

srobertstoms.rev77@gmail.com (Steve Roberts) — Wed, 14 May 2025 22:24:36 GMT

Mixed-use buildings create unique challenges for HVAC system design . Whether it’s a property that combines office space with a warehouse, retail storefronts with administrative areas, or worship spaces with classrooms, each zone comes with its own requirements for temperature, airflow and noise. The key to success is designing around how each part of the building is actually used.

Different Spaces Mean Different HVAC Priorities

Offices and Schools

Offices where every worker is sitting in front of a heat-generating computer need a consistent, low-noise temperature control solution.

Schools can have similar environments but also more variation in occupancy. Some rooms may require robust cooling output while others sit empty, and which rooms are empty and full can change throughout the day.

In both environments, low noise and good filtration are needed to maintain comfort and productivity.

Variable occupancy necessitates a combination of effective zoning and the ability to provide consistent, powerful output. These types of environments, where potentially dozens of people are sitting in close proximity for many hours at a time, also benefit from robust indoor air quality solutions.

Retail Spaces

While retail spaces can also deal with high occupancy during some parts of the day, they often feature larger open floor plans with higher ceilings than a typical office or classroom. They may also have large windows that let in heat-generating sunlight, heavy foot traffic coming in and out of exterior doors, and long operating hours. Strong cooling performance and stable airflow are vital attributes for a retail HVAC solution.

Warehouses or Storage Areas

What a warehouse or storage area is used for is a key determinant for the space’s temperature and climate control requirements. These commercial spaces typically have the most variability in their climate control needs.

A warehouse storing items that are not temperature sensitive may require relatively minimal climate control but good ventilation. A warehouse used for manufacturing with heat-producing machinery and workers on the floor throughout the day might require robust cooling output and high-powered air purification to deal with airborne particles. Some may also have loading docks that are opened frequently, which can let out large volumes of conditioned air.

Houses of Worship, Auditoriums and Theaters

These types of spaces pose some unique climate control challenges due to their size and occupancy variations. When they’re full during services, performances or events, they create large cooling loads, but they have very minimal demand the rest of the time.

IT rooms and equipment closets

These rooms can generate significant heat that must be rapidly removed to prevent damage and maintain functionality. Server rooms and data centers in particular require specialized robust cooling capacity that provides both redundancies and consistent round-the-clock output. For some businesses or campuses, these rooms may require dedicated exhaust or cooling solutions.

The Importance of Zoning in Mixed-Use Design

Some organizations or businesses may have properties that have multiple different types of zones. A school may have dozens of classrooms as well as a gym, auditorium and cafeteria. Warehouses often have both warehouse storage and manufacturing spaces as well as some administrative office space. Some retailers have large open sales floors plus a large storage space and loading docks in the back. Universities may have all of the above as well as IT rooms and equipment closets that facilitate connectivity on a large campus.

Effective zoning is the most dependable way to manage diverse HVAC needs while minimizing energy waste and reducing wear.

Matching the Right Equipment to the Layout

HVAC equipment selection plays a critical role in performance and comfort. The best system for a multi-tenant office won’t necessarily be the right fit for a facility with open-floor retail and back-end storage.

Some properties benefit from a centralized rooftop unit paired with ductless mini-splits in smaller or isolated offices. Others may be better served by multiple split systems or a variable refrigerant flow (VRF) system that offers precise control across a wide layout.

Design recommendations should account for square footage, how isolated each zone is, how much control each requires, and how it’s occupied throughout the week. There’s not always a clear one-size-fits-all solution for multi-use buildings or campuses.

Maintenance Access Implications

In many mixed-use buildings, equipment is tucked above drop ceilings or hidden in hard-to-reach corners. That may save space on paper, but it can create challenges when it’s time to perform routine maintenance, fix damaged ductwork or replace components.

Accessible filter locations, service panels and coil access points should be part of the design, not an afterthought. Spaces like tech rooms or frequently occupied offices will require more regular upkeep than a back room that only gets used for storage. HVAC installation professionals should plan your layout not just for installation, but for long-term serviceability as well.

Why Older Commercial Buildings Are Prone to HVAC Short Cycling and What to Do About It

srobertstoms.rev77@gmail.com (Steve Roberts) — Wed, 14 May 2025 22:03:18 GMT

Short cycling is when your system turns on, runs for a short time, and then shuts off before completing a full heating or cooling cycle. It’s one of the most common, and most frustrating, issues affecting HVAC systems in older commercial structures.

Short cycling is more than just an annoyance because it wears out your equipment, reduces energy efficiency and often fails to maintain proper indoor comfort.

What Causes Short Cycling in Older Buildings?

Although there could be a single failing component or problem causing short cycling, it’s not uncommon for the phenomenon to be attributable to overlapping issues. Older buildings in particular tend to have certain characteristics that make short cycling more likely.

Outdated or Oversized Equipment

Many older buildings have had HVAC systems replaced over time, but not always with equipment that matches the building’s current needs. If a newer unit was oversized to “cover more ground,” it may cool or heat the space too quickly, triggering the thermostat to shut it off before completing a full cycle. This quick on-and-off pattern leads to excess wear and poor humidity control.

Poor Insulation or Airflow Design

A building with drafty windows, damaged insulation or irregular duct layouts can experience uneven temperature swings that confuse the thermostat. This causes the system to turn on and off more frequently as it attempts to compensate.

Improper Thermostat Placement

Older buildings may still rely on thermostats installed decades ago, sometimes in poor locations like near doorways, vents or sun-exposed walls. Improper thermostat placements can cause inaccurate temperature readings that result in the system cycling unnecessarily.

Electrical or Control Board Issues

Faulty wiring or aging control systems can misfire, signaling the unit to shut off early even when no temperature change has occurred. These problems are especially common in buildings with outdated breaker panels or inconsistent power delivery to rooftop units.

Why Short Cycling Is a Problem You Can’t Ignore

When your HVAC system short cycles, it never gets the chance to operate at its most efficient level. The system draws the most electricity at startup, and repeated cycling leads to wasted energy, uneven temperatures and extra strain on critical components like compressors and blower motors.

In commercial buildings, this can result in:

Higher energy bills
Increased complaints from occupants or tenants
Reduced indoor air quality and humidity control
Premature equipment failure

What to Do About Short Cycling in a Commercial Property

The cost and complexity of fixing short cycling can vary significantly based on the cause. If it’s something simple like loose connections, a failing control board or an old thermostat, the issue might not be expensive to fix. If the short cycling is due to fundamental ductwork or system problems, the solution can be more complicated.

Evaluate Equipment Sizing

If your system is oversized for your space, a technician may recommend staging solutions, zoning upgrades, or, in some cases, a properly sized replacement. Correctly sizing a system helps it run longer, more efficient cycles without overcooling.

Inspect Ductwork and Insulation

Professional ductwork evaluation can reveal air leaks, uninsulated ducts or disconnected zones that may be undermining airflow. Fixing these problems can stabilize temperatures and reduce unnecessary cycles.

Assess Thermostat Location and Calibration

Relocating or upgrading one or more of your building’s thermostats may solve cycling issues caused by inaccurate readings. Many newer models include sensors to average out readings from multiple zones.

Repair or Replace Failing Components

Sometimes the problem comes down to a bad capacitor, dirty coils or shorted wires, all of which are relatively affordable repairs if caught early.

Consider Control Upgrades

Older buildings may benefit from upgrading to digital controllers or building automation systems that give you better scheduling, zoning and diagnostic capabilities.

Get a Solution to Your Building’s Air Conditioner Problems

Short cycling, as well as other air conditioning performance problems, won’t fix themselves. If your system is turning on and off too frequently, or your indoor comfort seems to be in decline, you should call a commercial HVAC specialist as soon as possible. The longer a problem remains unresolved, the more it may cost to repair.

The Arlington commercial HVAC specialists at Tom’s Commercial can identify the root cause of your system’s problems and recommend the best long-term solution for your building and budget.

What to Do When a Single Zone Is Too Hot or Too Cold in a Commercial HVAC System

srobertstoms.rev77@gmail.com (Steve Roberts) — Mon, 12 May 2025 22:16:48 GMT

It’s a common problem in commercial buildings: one zone is constantly too hot or too cold while the rest of the building stays comfortable. It could be a storage area, a corner office, or a conference room that never seems to reach the right temperature no matter how long the cooling system runs. These kinds of problems are often more than just comfort issues. They point to larger problems with airflow, zoning or equipment configuration.

Airflow Imbalance

A damper might be stuck open or closed, or a duct branch may have come loose, restricting airflow into one part of the building. In zoning systems, a single damper failure can throw off the temperature in an entire wing. Because dampers are in ductwork and ductwork is often hidden in drop ceilings or mechanical spaces, diagnosing a problem with one can be tricky. A technician can measure airflow and pressure to identify whether the zone is getting what it should.

Thermostat Issues

A malfunctioning or poorly placed thermostat can easily throw off temperature control in a single zone. If the thermostat is located near a heat source, drafty door or in direct sunlight, it may be misreading the room’s true temperature and telling the system to turn on or off at the wrong time. For example, a thermostat on an east-facing wall in a conference room with a big window might have its reading thrown off in the morning.

Outdated thermostats can also struggle to communicate properly with the rest of the HVAC system, especially in older zoning setups where multiple zones share a controller.

Sensor Failure

Some larger commercial HVAC systems rely on remote temperature sensors instead of wall-mounted thermostats. When one of these sensors fails or falls out of calibration, it can send inaccurate temperature readings back to the central controller. The system thinks the room is warmer or cooler than it really is, which leads to improper cycling or dampers opening and closing at the wrong time. These types of failures can go unnoticed for weeks unless someone flags the temperature issue in the affected area.

Filter or Vent Blockage

If air can’t circulate properly in or out of a zone, that space will always lag behind the rest of the building. Blocked return vents, dirty supply registers or an overloaded air filter can all reduce airflow. This is one of the easier problems to check, which is good since it’s also one of the most common and overlooked issues.

Even a mostly clean filter can become restrictive when airflow is marginal or when a zone is located farther from the central unit.

Duct Sizing or Insulation Problems

Ductwork that’s too small, runs too far or lacks proper insulation will lose temperature before the air ever reaches the vent. This is especially common in older commercial buildings where duct runs have been extended during renovations, or where a system was never fully redesigned after a tenant improvement.

A room at the end of a long, uninsulated duct in the summer might receive cool air that’s already warmed up by the time it gets there.

What You Can Do Right Now

If you’re dealing with one zone that never seems to match the rest of the building, there are a few simple checks to try before calling in a technician:

Make sure vents and returns aren’t blocked by equipment, shelving or furniture
Change the air filter if it’s dirty or hasn’t been replaced in the past few months
Confirm the thermostat or sensor in that zone isn’t exposed to unusual heat, cold drafts or direct sunlight
If the issue is recent, consider whether any layout or occupancy changes may have affected the zone’s airflow or insulation needs

How a Commercial HVAC Technician Can Diagnose the Problem

A commercial HVAC technician can inspect the zone’s ductwork, damper operation, thermostat performance and system response to determine what’s going wrong. Sometimes the problem lies in something simple, like a loose wire or failing actuator. Other times, it may require a more in-depth fix such as rebalancing duct branches or upgrading components in a legacy zoning system.

Either way, a targeted inspection can help avoid wasting money on system-wide overhauls when the issue is isolated.

What Facility and Regional Managers Should Look for in a Commercial HVAC Company

srobertstoms.rev77@gmail.com (Steve Roberts) — Wed, 23 Apr 2025 21:33:24 GMT

Choosing the right HVAC partner isn’t just about fixing problems; it’s about avoiding them in the first place. For facility and regional managers juggling multiple responsibilities, HVAC should be low-touch, consistent and professionally managed. If you’re considering a switch from your current provider, here’s what to prioritize.

Consistency From One Visit to the Next

One of the most common frustrations managers experience with their commercial HVAC company is having to re-explain the layout of their building every time a tech shows up—where the ladder is, which breaker controls which unit and so on.

A reliable HVAC partner will document all of this up front and keep it on file. At Tom’s Commercial, our techs show up with maps, notes and photos so they know exactly where to go and what to do. We don’t need handholding and take pride in offering dependable, unobtrusive service.

Experience With Commercial-Scale Challenges

Not all HVAC contractors are built for large-scale commercial jobs. You need a company with proven experience servicing large properties, coordinating with facility managers and working within commercial infrastructure. From rooftop units and zoning issues to airflow complaints and duct layout fixes, they should already be familiar with the problems you're facing. No facility manager wants to pay a company to learn on their dime.

Follow-Through and Accountability

A lot of managers come to us after dealing with companies that promised great service but failed to follow through. Maybe the maintenance team only showed up once or twice during the past year despite charging for quarterly service. Maybe they left used filters or scrap on your property’s roof where they assume you’ll never look. A good HVAC company keeps its word, cleans up after itself and shows up when scheduled—without cutting corners.

Custom Service Plans That Actually Fit

Commercial buildings aren’t all the same, and your service plan shouldn’t be either. Look for a provider that can tailor maintenance schedules and services to match how your building is used. For example, an industrial facility might need frequent filter changes due to airborne particulates, while a school campus might require service that works around academic schedules. Flexibility and attention to detail are key.

Smart Problem-Solving, Not Just Parts Swapping

When something goes wrong, you don’t just want a diagnosis—you want options. A reputable and dependable commercial HVAC provider should approach issues with critical thinking and creativity.

On one recent repair job, we helped a property owner who was told by another company that they’d need a helicopter to install a new rooftop unit—at a cost nearly twice the price of the unit itself.

Our team determined we could use a long-reach forklift from a neighboring parking structure to get the new unit up to the roof, completing the job safely and cost-effectively without the added expense.

Creative thinking can make a huge difference in both budget and outcome—especially when space is tight or access is limited.

Professionals You Don’t Have to Babysit

The best commercial HVAC companies understand that managers don’t want to micromanage contractors. Look for providers that will stick to their commitments without needing constant oversight. We’re committed to working around your schedule, cleaning up after ourselves and adjusting our services to your facility and use requirements.

Scalable for Multi-Site Management

If you oversee multiple buildings, your HVAC company should be able to service them all while maintaining consistency. That includes shared documentation, informed tech teams and centralized reporting—so you’re not juggling six different points of contact.

Knowledge of Codes, Compliance and Quotes

Property and facility managers are often required to get multiple quotes before choosing an HVAC company for system replacement. For some, this step is more of a formality, since they already assume they know which company they’re going to choose from the start. Our team at Tom’s Commercial would appreciate the opportunity to earn your business.

We’re committed to showing Arlington and DFW-area businesses what it’s like to work with someone who understands how to navigate that process and provides transparent, easy-to-compare estimates. You may find that our commercial HVAC installation team has creative solutions others missed.

Do Building Materials Matter When It Comes to HVAC Installation?

srobertstoms.rev77@gmail.com (Steve Roberts) — Wed, 16 Apr 2025 21:44:20 GMT

When you’re planning an HVAC upgrade or replacement, it’s easy to focus only on equipment specs and unit capacity. But there’s a major factor that often gets overlooked: your building’s construction. The materials used in your walls, roof, insulation and windows can have a huge impact on how your system performs, and whether the installation process goes smoothly.

Insulation and Envelope Quality Influence System Sizing

A building’s insulation and overall envelope efficiency directly affect how much heating and cooling power is needed. Older buildings with poor insulation or outdated construction methods often require larger or more powerful systems to achieve the same comfort levels.

On the other hand, well-insulated structures can often get better results with smaller, more efficient units. Commercial HVAC installers should take that into account when recommending equipment, so you don’t end up with an oversized system burning more energy than necessary or an undersized one that can’t keep up.

Window Type and Placement Affect Load Balance

If your building has large windows, especially on sun-exposed walls, they’ll influence indoor temperatures more than you might expect. Single-pane glass, poor seals or a lack of shading can all contribute to excessive heat gain, especially in Texas summers. A proper HVAC design considers these factors and may include zoning strategies or additional airflow controls to prevent hot or cold spots near windowed areas.

Roofing and Wall Materials Impact Temperature Control

Metal roofs and lightweight siding can absorb and radiate heat quickly, creating a significant challenge for cooling systems. Brick or stone walls may retain heat longer, making it harder to cool down in the evenings. These characteristics all affect how your building responds to temperature changes—and need to be factored into system sizing and airflow planning.

Building Materials Can Complicate HVAC Replacement Logistics

Sometimes it’s not just about performance—it’s about getting the equipment in place. Heavy roofing materials, dense framing or older wall systems may not support modern units without reinforcement. Other times, routing ductwork through tight attic or crawlspace areas becomes difficult due to the way the building was originally constructed. Commercial HVAC companies need to review those access points ahead of time to prevent delays, safety issues or last-minute changes to the plan.

Ventilation Design Must Match Building Composition

The way a building is sealed also affects ventilation. Structures built with tighter envelopes need carefully planned ventilation to maintain indoor air quality and prevent humidity issues. Older, more porous buildings might allow unintentional air exchange, requiring system adjustments to keep air flowing properly and efficiently.

Retrofits Require Even Closer Attention to Materials

If you're upgrading or supplementing an HVAC system in an existing building, building materials become even more important. Many older commercial properties weren’t designed with today’s HVAC standards in mind. You may run into limited access for ductwork, roof structures that can’t support modern unit weights or older materials that make cutting or sealing more difficult.

Retrofit projects can stall if the installer didn’t anticipate these challenges—or worse, installed a system that couldn’t perform well due to structural limitations.

Commercial HVAC companies shouldn’t just bid based on cursory analysis; they need to look ahead at what modifications or changes might be required for proper implementation. Contractors should evaluate things like roof access, framing, insulation and how new components will integrate with your existing ductwork and layout.

Our commercial HVAC installation professionals always look for potential issues ahead of time and explain options before work begins, so there are no surprises midway through. Thorough planning saves time, avoids costly delays and ensures the new system will perform the way it’s supposed to without forcing you to drastically modify your building just to make it work.

Our Installation Teams Account for Building Materials from Day One

We’ve worked on everything from industrial warehouses and schools to churches and office buildings—and we know that the best system on paper can fall short if it’s not designed for the space it serves.

That’s why we don’t just quote a unit based on square footage. We assess how your building is built, what kind of thermal challenges it creates and how to get the equipment installed safely and effectively . If there’s a smarter way to do the job—like using a different system style or a creative install method—we’ll find it.

Call Tom’s Commercial at 817-857-7400 for a solution designed around your building.

Why Call Tom’s Commercial for a Second Opinion?

srobertstoms.rev77@gmail.com (Steve Roberts) — Wed, 16 Apr 2025 21:37:57 GMT

Getting a second opinion for HVAC replacement isn’t about starting from scratch. It’s about making sure the plan you’re presented with is the right one. For facility and regional managers, especially those required to gather multiple quotes, a second opinion can help confirm you're making the best long-term decision for your building, budget and operations.

Second Opinions Can Add Value

For many facility managers, getting a second or even third bid for HVAC replacement is a formality. Decision-makers may already have a preferred vendor or plan in mind, but still need to check the box. At Tom’s Commercial, we don’t treat these requests as throwaway quotes. We approach every second opinion as an opportunity to uncover potential cost savings, find smarter alternatives or spot red flags in the original recommendation.

Even if you already have a frontrunner, it's worth letting us take a look. You might be surprised at what we notice.

Replacements Aren’t Always One-for-One

When it’s time to replace a unit, it’s not always as simple as swapping in a comparable model. Depending on your building’s layout, usage patterns or equipment access, the original system might not be the best fit anymore. Sometimes the replacement requires a totally different style of unit or a change in how the system is zoned. Our team doesn’t just price out what’s easiest to install. We look at the big picture and provide solutions tailored to your space and long-term needs.

Our Process Is Built for Clarity

HVAC estimates can get technical fast. We make sure ours are written in plain language, with clear breakdowns that are easy to compare. This approach can be especially helpful for decision makers who need to justify costs internally or get approvals.

We also take the time to explain why we’re recommending what we are, whether it’s a comparable unit or a more efficient option based on your usage.

We’ll Give You a Clear Plan—Not Just a Number

A second opinion from Tom’s Commercial isn’t just a quote. It’s a plan. We evaluate your building, the existing equipment and any pain points you’ve mentioned. Then we give you a proposal that considers not just installation logistics but also long-term maintenance access, energy efficiency and comfort. If there’s a more practical way to do the job, or a way to save money without cutting corners, we’ll find it.

We Think Beyond the Obvious

We’ve stepped into situations where other companies quoted convoluted installation plans that drive up the cost before the job even started. In one case, we used a long-reach forklift from a nearby structure to safely place a new unit without a helicopter, saving the client thousands. A second opinion isn’t just about price. It’s about seeing the full scope of options and working with a team that thinks critically about your situation.

Unbiased Advice—Even if You Don’t Hire Us

Not every second opinion leads to a new client, and that’s okay. We don’t approach these situations with a hard sell. Our goal is to give facility managers clarity, not pressure. If we agree with your first quote, we’ll tell you. If we see a better approach, we’ll explain it.

You get real information from a team that wants long-term partnerships, not quick wins. Even when a client decides to move forward with another contractor, they often come back to us down the line because they remember we handled their second opinion with honesty and transparency.

Second Opinions Can Reveal Bigger Picture Issues

Sometimes it’s more about the overall approach than the quote. If one contractor is focused only on replacing parts without asking why the system failed, they may be missing larger airflow issues, equipment mismatches or overlooked maintenance lapses.

A second opinion can bring those blind spots to the surface. For example, we might find that a repeated cooling issue isn’t a unit problem, it’s an airflow bottleneck caused by improperly sized ductwork. Catching those problems before you invest in new equipment can save thousands and significantly improve performance.

What You Should Do if You Have Cracks at Seams on the Ducts in Your Commercial Building

srobertstoms.rev77@gmail.com (Steve Roberts) — Thu, 10 Apr 2025 21:24:08 GMT

Your ductwork is the unsung hero of your HVAC system, quietly moving conditioned air where it needs to go to maintain a comfortable indoor environment . If cracks or gaps start to form at the seams, your system’s efficiency and performance can suffer. In commercial buildings, these issues can go unnoticed for months until uneven temperatures, airflow problems or rising energy bills start to raise red flags.

Why Duct Cracks Happen in Commercial Buildings

Cracks and separated seams in ductwork don’t happen overnight. They’re usually the result of long-term stress, aging materials or overlooked installation flaws. Some of the most common reasons cracks begin to form include:

Aging materials: Over time, duct sealants like mastic and foil tape can break down, especially in hot or humid environments. As the material dries out or deteriorates, seams become vulnerable to cracking or peeling, allowing conditioned air to escape.
Improper installation: If the ductwork wasn’t supported properly or if low-quality materials were used during the original installation , seams can begin to separate much sooner than they should. Joints that were never fully sealed or were only sealed using temporary tape can fail within a year of installation.
Vibration and movement: Rooftop units and large air handlers create constant vibration that puts stress on ducts—especially where joints and elbows are involved. Over time, this movement can cause rigid connections to crack or pull apart.
Thermal expansion and contraction: In climates like Arlington and Dallas–Fort Worth, where outdoor temperatures swing drastically, duct materials expand and contract every day. This constant movement can gradually weaken joints and connections, particularly in unconditioned spaces like attics or mechanical rooms.
Building settling or structural shifts: Even slight structural movement in an aging building can strain duct runs. If the framing shifts, it may tug on connected ducts, causing them to twist, bow or pull away from their original connection points.
Pressure imbalances: If your system is producing too much positive or negative pressure due to zoning issues or blocked airflow, that extra strain can force air against seams and wear them down faster than normal.

How to Spot the Problem

Cracks allow conditioned air to escape into attics, crawlspaces or wall cavities, forcing your system to work harder than it should.

Some cracks may be hidden from view due to duct placement, but you’ll feel the effects. Hot or cold spots, reduced airflow and inconsistent temperatures between zones could indicate a ductwork breach. If your energy bills have crept up without explanation, it’s worth inspecting the duct system.

Don’t Patch It Blind—Get a Proper Inspection

A lot of maintenance professionals in commercial facilities try to apply a quick fix using foil tape or sealant, but that’s only effective if you’ve identified the full extent of the issue. Small gaps may indicate larger separations further down the line.

Tom’s Commercial uses professional diagnostics to check the integrity of the system—not just the spot that’s leaking. We’ll assess pressure imbalances, material breakdown and access points to recommend a fix that actually solves the problem.

Cracked Ducts Can Be Repaired—But Only if Done Right

Depending on the condition and location of the damage, we may be able to reseal and reinforce existing sections or recommend a full replacement of affected runs. For older buildings, it’s often more cost-effective to upgrade the worst sections rather than continuing to chase down leaks every season.

We always take into account your building layout, usage patterns and access limitations before making a recommendation.

Proactive Maintenance Prevents Recurring Issues

Once the cracks are repaired, the best way to keep them from coming back is with regular maintenance . If your building experiences a lot of vibration, thermal swings or high airflow demands, your HVAC service provider should be adjusting their ductwork inspections accordingly.

Need a Duct Inspection or Second Opinion in Arlington?

If you’ve spotted a seam pulling apart or suspect airflow loss due to a hidden leak, don’t wait. The longer air escapes, the more strain you put on the system and the higher your temperature control costs climb. Tom’s Commercial can inspect, diagnose and repair duct damage with minimal disruption to your business. Call us at 817-857-7400 for duct inspection or repairs.

The Importance of Exhaust Fans in Industrial Facilities

srobertstoms.rev77@gmail.com (Steve Roberts) — Fri, 14 Mar 2025 23:20:11 GMT

In industrial settings, maintaining air quality, temperature control and safety is critical. Exhaust fans play a key role in removing contaminants, excess heat and moisture from work environments. These systems should be designed to meet structural and performance needs, improving worker safety, protecting equipment and maintaining regulatory compliance.

How Exhaust Fans Work

Exhaust fans work by drawing contaminated or hot air out of a space and replacing it with fresh air. These systems are commonly installed in factories, warehouses, workshops and processing plants where airborne pollutants, heat and humidity rapidly accumulate as a result of operations.

Key Functions of Industrial Exhaust Fans

Removing airborne contaminants such as dust, smoke and fumes.
Reducing excess heat from equipment, processes and high-temperature work areas.
Controlling humidity and moisture to prevent mold growth and corrosion.
Improving air circulation for worker comfort and compliance with safety regulations.

Types of Industrial Exhaust Fans and Their Applications

Centrifugal Fans

These high-pressure fans are ideal for facilities dealing with dense airborne contaminants, such as dust and chemical fumes. Their design allows for better filtration and controlled air movement, making them a popular choice in manufacturing and chemical processing plants.

Axial Fans

Designed for moving large volumes of air at lower pressure, axial fans are commonly used for general ventilation in warehouses and large open spaces. They help circulate air effectively, reducing stagnant zones where heat or fumes can accumulate.

Upblast and Downblast Roof Fans

These roof-mounted exhaust systems help remove heat, smoke and airborne pollutants from industrial spaces. Upblast fans push air upward and away from the building, while downblast fans direct airflow downward for localized ventilation needs.

Wall-Mounted Exhaust Fans

Often used in areas where targeted airflow is needed, wall-mounted fans help remove contaminants from specific workstations, such as welding bays or paint booths. They provide a cost-effective ventilation solution for localized air quality control.

Ducted Exhaust Systems

In environments with strict air quality requirements, ducted exhaust systems are custom-built to ensure optimal ventilation. These systems are commonly found in laboratories, pharmaceutical plants and food processing facilities where precise control over air movement and filtration is essential.

The Role of Exhaust Fans in Industrial Applications

Controlling Particulate Matter in Manufacturing

Manufacturing processes, especially those involving cutting, grinding, welding or chemical treatments, generate fine dust and fumes that can pose serious health risks. Exhaust fans help:

Filter and expel particulates before they accumulate in work areas.
Improve indoor air quality (IAQ), reducing exposure to harmful airborne substances.
Extend equipment life by preventing dust buildup in machinery.

Removing Fumes and Gases in Refining and Chemical Processing

Industries like petrochemical refining, metal plating and pharmaceutical production release hazardous gases and vapors that must be properly ventilated. Without exhaust fans, workers can be exposed to harmful chemicals, and combustible fumes may create safety hazards. High-powered exhaust systems are used to:

Extract and neutralize toxic emissions before they reach dangerous levels.
Maintain compliance with OSHA and EPA air quality regulations.
Prevent corrosion by removing airborne chemicals that can damage metal surfaces.

Heat Control in High-Temperature Environments

Industrial facilities often generate high heat loads from heavy machinery, ovens and manufacturing processes. Exhaust fans contribute to:

Reducing indoor temperatures, making workspaces more comfortable.
Preventing heat buildup, which can affect equipment performance.
Enhancing HVAC efficiency and lowering cooling costs by improving air exchange.

Moisture and Humidity Management

Certain industrial processes generate high levels of moisture, which can lead to mold, rust and structural damage. Exhaust fans help:

Regulate humidity to prevent moisture buildup.
Protect materials and equipment from water-related degradation.
Improve overall air quality by reducing the risk of condensation.

Energy Efficiency and Cost Savings with Industrial Exhaust Fans

Industrial facilities often invest heavily in powerful HVAC systems for temperature control, but ventilation can play a significant role in lessening the burden on cooling systems and enhancing energy efficiency.

Exhaust fans that remove excess heat, moisture and contaminants reduce the workload on air conditioning systems. Without proper ventilation, cooling systems must work harder to maintain comfortable temperatures, leading to increased energy consumption and higher utility bills.

Strategically placed exhaust fans improve airflow efficiency by ensuring conditioned air is distributed effectively throughout the facility. Advanced models with variable speed motors adjust airflow based on demand, further optimizing energy use.

Choosing the Right Exhaust Fan for Your Facility

Selecting the right exhaust fan depends on the specific needs of your industrial space. Factors to consider include:

Airflow capacity (CFM) – The volume of air the fan can move per minute.
Static pressure requirements – The resistance to airflow within ducts and ventilation systems.
Material compatibility – Corrosion-resistant materials for chemical environments.
Noise levels and efficiency – Balancing performance with workplace comfort.

Ensure Proper Ventilation with Professional Exhaust System Design and Installation in Arlington

Industrial exhaust systems must be designed and installed correctly to ensure optimal performance and regulatory compliance.

How to Combat Humidity with a Commercial HVAC Unit

srobertstoms.rev77@gmail.com (Steve Roberts) — Fri, 14 Mar 2025 23:09:25 GMT

Excess humidity in a commercial building can lead to discomfort, mold growth, equipment damage and decreased air quality. In Arlington, TX, where humidity fluctuates throughout the year, businesses need effective climate control solutions to maintain a balanced indoor environment.

One key difference between commercial HVAC systems and the residential systems most people are familiar with is humidity control. Large buildings with variable occupancy present unique challenges in maintaining consistent humidity levels, and commercial HVAC systems are designed to regulate moisture effectively despite these challenges.

Why Humidity Control Matters in Commercial Spaces

When indoor humidity levels rise above 50 to 60 percent, buildings may experience:

Poor air quality from increased mold, mildew and dust mites.
Uncomfortable indoor temperatures, making spaces feel warmer than they are.
Damage to electronics and equipment from excessive moisture.
Structural issues, such as condensation on windows, warped flooring and peeling paint.
Increased HVAC strain leading to higher energy costs and reduced efficiency.

Proper Sizing and System Configuration

A commercial HVAC system must be correctly sized to effectively regulate temperature and moisture levels. An oversized unit cools the space too quickly and may fail to effectively remove humidity before shutting off. A right-sized system runs long enough to dehumidify the air while maintaining consistent cooling.

Routine Maintenance for Optimal Dehumidification Performance

Even the most advanced commercial HVAC system can struggle with humidity control if it isn’t properly maintained. Over time, clogged filters, dirty coils and blocked drain lines can reduce efficiency and lead to excessive moisture buildup inside the building. Regular maintenance is essential for ensuring that the system continues to effectively regulate humidity and prevent costly issues.

Advanced Dehumidification Features in Commercial HVAC Systems

Dedicated Outdoor Air Systems (DOAS)

Unlike most residential systems, which primarily recirculate indoor air, DOAS units bring in fresh, conditioned air while actively managing humidity levels. These are commonly used in schools, offices and industrial buildings where consistent air exchange is necessary.

Reheat Coils for Dehumidification

Many commercial systems include reheat coils, which allow the HVAC system to remove moisture from the air without overcooling the space. This is useful in buildings where humidity fluctuates independently of temperature needs, such as churches and auditoriums.

Variable Speed Compressors and Fan Control

While some high-end residential systems have variable speed features, commercial HVAC units are often equipped with advanced humidity sensors and multi-stage controls that allow the system to adjust airflow and cooling power specifically for moisture removal.

Integrated Dehumidification Modes

Many commercial rooftop units (RTUs) and split systems have built-in dehumidification cycles that operate separately from cooling. These cycles use longer, slower cooling runs to maximize moisture removal without making the space too cold.

Makeup Air Units (MAUs) with Dehumidification

In larger commercial buildings, MAUs condition incoming air before it enters the space, reducing humidity at the source. This is especially critical for industrial facilities, warehouses and schools, where large amounts of air need to be conditioned efficiently.

Why Are Specialized Dehumidification Features So Important in Commercial Settings?

HVAC in commercial settings is complicated for a couple of reasons. First, commercial structures by their nature have much higher occupancy, more frequent exposure to outdoor air, and experience significant humidity fluctuations due to people, equipment and environmental factors.

Second, they have far more capacity than residential units because they must cool a much larger space. Oversized cooling systems can potentially struggle with humidity control in some circumstances because they can cool too quickly, meaning they don’t run long enough to properly dehumidify indoor air.

This is particularly common in commercial structures that experience varying occupancy levels and cooling needs at different times of day.

Some industries, like manufacturing or healthcare, may also have stringent humidity requirements that aren’t present in residential or other commercial applications. An HVAC system that effectively manages humidity without separate equipment can help extend system lifespan and improve air quality and comfort.

Split Unit vs. Straight Package Unit: Choosing the Right HVAC System for Your Business

srobertstoms.rev77@gmail.com (Steve Roberts) — Fri, 14 Mar 2025 23:00:18 GMT

Some property owners and facility managers may not begin seriously considering HVAC replacement options until their current system fails and they need to make a quick decision. Choosing the best system isn’t always easy. It’s a consequential decision with significant budgetary and performance ramifications.

The commercial HVAC professionals at Tom’s Commercial in Arlington are always prepared to provide a bid or second opinion quickly. We know you’re on a tight deadline and can quickly send someone to assess your property and provide a detailed estimate.

Two of the most popular systems for our clients in Arlington are split units and straight package units. Each is highly effective in our climate, and there are applications where either can provide effective cooling performance. There are also some situations where one option is clearly preferable.

What Is a Split Unit?

A split unit consists of two main components:

An outdoor condenser unit, which houses the compressor and cooling coil.
An indoor air handler, which circulates cooled air through the building.

These two components are connected by refrigerant lines, allowing the system to distribute conditioned air efficiently. Split units come in cooling-only and heat pump models, giving businesses the option for both heating and cooling in one system.

Best Applications for Split Units

Multi-zone buildings where different areas require independent temperature control.
Offices that need separate cooling for conference rooms, workspaces and lobbies.
Multi-family residential properties, where individual units need their own HVAC system.
Churches and schools that require zoning for classrooms, auditoriums and office spaces.

What Is a Straight Package Unit?

A straight package unit is a self-contained HVAC system that houses all components inside a single cabinet, including the compressor, condenser, evaporator coil and blower. These units are typically mounted on the roof or on a concrete pad outside the building and are ducted to distribute conditioned air.

Unlike package heat pumps, straight package units provide cooling only. Heating is handled separately, typically by a furnace or electric strip heater.

Best Applications for Straight Package Units

Warehouses and large industrial spaces that need powerful cooling with minimal indoor equipment.
Single-story office buildings where rooftop installations make sense.
Churches and schools looking for an all-in-one cooling solution.
Buildings with limited indoor space that benefit from an external unit.

Installation Considerations: Where and How They Can Be Installed

Split Unit Installation

Requires both indoor and outdoor space to accommodate the condenser and air handler.
Can be installed in a mechanical room, mounted on a ceiling or placed in an out-of-the-way space inside the building.
Typically requires a day or two for replacement, though additional time may be needed for new refrigerant lines or ductwork modifications.
Works well in buildings where zoning and flexibility are key considerations.

Straight Package Unit Installation

Installed on the roof or a ground-level concrete pad to save interior space.
Requires ductwork to distribute conditioned air inside the building.
Replacement of an existing unit typically takes a day, or slightly longer if structural modifications are needed for mounting.
Best suited for buildings designed with packaged unit installations in mind.

Cost Comparison: Which System Is More Expensive?

Upfront Equipment Cost

Split units are generally less expensive on a per-unit basis but may require additional components like an air handler or additional ductwork.
Straight package units have a higher upfront cost since everything is housed in one cabinet, but they simplify installation.

Installation Costs

Split units may require more labor due to refrigerant line installation and zoning configurations, which can drive up costs.
Straight package units tend to have lower installation costs since they come pre-assembled and only require placement and ductwork connection.

Maintenance and Longevity

Split units have separate components, which can make individual part replacements easier and more cost-effective over time.
Straight package units are fully contained, making routine maintenance simpler, but if a major component fails, replacing the whole unit may be necessary.

Energy Efficiency and Long-Term Costs

Split systems can offer better energy efficiency, particularly when multiple zones are needed, leading to long-term savings.
Straight package units are efficient in large, open spaces but may not be as cost-effective in buildings that need temperature zoning.

Which System Is Right for Your Arlington Business?

Both split units and straight package units offer benefits depending on your building layout, cooling needs and budget. If flexibility and zoning are important, split units may be the better choice. If you need a space-saving, all-in-one cooling system, a straight package unit might be the right fit.

Types of HVAC Systems for Commercial Properties in Arlington

srobertstoms.rev77@gmail.com (Steve Roberts) — Fri, 14 Mar 2025 22:44:47 GMT

Choosing the right HVAC system is critical for maintaining comfort and efficiency in commercial buildings. In Arlington, TX, and the greater Dallas - Fort Worth area, businesses and institutions rely on different types of HVAC systems to meet their specific needs.

Some organizations rely on precise climate control for their operations, while others prioritize balancing performance with affordability. For businesses with specialized needs, one HVAC system may be clearly superior, but most commercial properties can choose from multiple effective temperature control solutions.

At Tom’s Commercial, we’re committed to offering solutions tailored to your facility’s specific needs and your organization’s budget.

Packaged Rooftop Units (RTUs)

Widely used in schools, offices and houses of worship, packaged rooftop units (RTUs) are self-contained systems installed on the roof. They provide heating and cooling by drawing in outside air, conditioning it and distributing it through ductwork. RTUs are valued for their space-saving design, energy efficiency and ease of maintenance .

Straight Packaged Units

A straight package unit is a type of packaged HVAC system that provides only cooling. It includes all components—compressor, condenser, evaporator coil and blower—housed in a single outdoor unit, which can be installed on the roof or ground.

Unlike heat pump package units, which can provide both heating and cooling by reversing the refrigerant flow, a straight package unit requires a separate heating system, such as an electric strip heater, gas furnace or boiler.

These units are common in warmer climates like DFW, where cooling demand is high and buildings may use a separate heating source when necessary. They are often used in offices, schools and industrial facilities.

Split Systems

Split systems consist of separate indoor and outdoor units and are commonly used in multi-family residential buildings and smaller commercial offices. These systems offer flexible installation options and can be customized for different spaces. They are often chosen for their affordability and efficiency in moderate-sized buildings.

Variable Refrigerant Flow (VRF) Systems

VRF systems are ideal for multi-zone buildings such as office complexes and schools. They use refrigerant as the cooling and heating medium, allowing for simultaneous heating and cooling in different areas of a building. These systems are known for their energy efficiency, precise temperature control and quiet operation.

Chilled Water Systems

Industrial facilities and larger institutions often use chilled water systems for cooling. These systems circulate chilled water through a network of pipes to air handling units, which then distribute cool air throughout the building. Chilled water systems are known for their scalability and ability to provide consistent cooling for large spaces.

Boilers and Hydronic Heating Systems

Houses of worship, schools and some industrial facilities use boilers for heating. Hydronic heating systems distribute hot water or steam through radiators, baseboard heaters or in-floor heating systems. These systems provide even, consistent heat and can be more energy-efficient than forced-air heating in certain applications.

Makeup Air Units (MAUs) and Dedicated Outdoor Air Systems (DOAS)

Industrial buildings and schools often require fresh air ventilation, which is where makeup air units (MAUs) and dedicated outdoor air systems (DOAS) come in. These systems improve indoor air quality by bringing in fresh air while maintaining proper temperature and humidity levels.

Heat Pumps

For energy-efficient heating and cooling, heat pumps are a popular choice in office buildings and multi-family residential properties. Air-source and ground-source (geothermal) heat pumps can provide year-round climate control by transferring heat rather than generating it.

Custom HVAC Solutions for Industrial Facilities

Industrial facilities often require specialized HVAC systems tailored to their specific operational needs. Whether managing air quality in manufacturing facilities or maintaining precise temperature control in warehouses, custom-engineered HVAC solutions ensure efficiency and compliance with regulatory standards.

Choosing the Right Heating and Cooling Solution for Your Facility in Arlington

Selecting the right commercial HVAC system depends on building size, occupancy levels and budget. Whether you manage a school, house of worship, office, industrial facility or multi-family property, working with a qualified commercial HVAC company in Arlington is the most reliable way to ensure your system meets your performance needs.

HVAC Units and Best Practices for Regulating Temperature in Schools

srobertstoms.rev77@gmail.com (Steve Roberts) — Fri, 21 Feb 2025 19:14:25 GMT

School buildings present a distinct set of HVAC challenges. With dozens of classrooms, long hallways, cafeterias, gyms and administrative areas, each with different heating and cooling needs, effective climate control in schools requires more than just raw output. Comfort, air quality, energy efficiency and noise levels are all factors to consider when choosing a climate control solution that will support learning in an environment where students and teachers can thrive.

Common HVAC Challenges in Schools

High Occupancy During Fixed Hours

Schools tend to have dense populations confined to specific zones at consistent times—like morning class blocks or lunchtime. HVAC systems need to deliver consistent comfort to large groups of people without overheating or overcooling unoccupied areas.

Poorly Balanced Airflow Between Zones

Older school buildings often have uneven air distribution, resulting in classrooms at the ends of hallways becoming too hot or too cold. Updating duct design or using zoned systems can help address this.

Aging Infrastructure

It’s no secret that district facility managers and infrastructure professionals face tight budgetary constraints in Arlington and throughout the DFW area. While the taxpayers may appreciate a budget-conscious approach to facility management, the cost limitation can lead to uncomfortable environments that detract from the educational experience. Many schools still operate on legacy HVAC systems installed decades ago. These units are often oversized, inefficient and not compatible with modern zoning or automation technologies.

Indoor Air Quality Requirements

Good ventilation and humidity control are essential in schools, where poor indoor air quality can lead to discomfort, distraction or even increased illness transmission. Air quality is particularly important in a high-occupancy setting notorious for virus and bacterial transmission. This can be further complicated by the diversity of health challenges children can face, including allergies, childhood asthma and other chronic respiratory conditions.

Noise Sensitivity

Loud equipment can interfere with instruction and learning, so quiet HVAC operation is especially important in classrooms and libraries.

System Features That Make a Difference in Schools

Zoning and Smart Controls

Zoned systems and programmable thermostats allow schools to adjust heating and cooling based on room usage and occupancy. This not only saves energy but also avoids discomfort in less-used spaces.

Demand-Controlled Ventilation (DCV)

DCV systems adjust fresh air intake based on occupancy and CO₂ levels, improving air quality without wasting energy.

Humidity Control

Especially in the DFW area, where hot and humid days are common, HVAC systems should regulate humidity to maintain comfort and protect school infrastructure like gym floors and instruments.

High MERV or HEPA Filtration

Modern systems should be compatible with advanced filtration to capture airborne particles, allergens and pathogens—particularly important in densely occupied spaces.

Systems That Work Well in School Environments

Packaged Rooftop Units (RTUs)

RTUs are a popular option for many school buildings with flat roofs. They’re easy to install, service and replace, and they can be zoned to serve different parts of the building.

Variable Refrigerant Flow (VRF) Systems

VRF systems offer high efficiency and precise control. They’re particularly effective in schools with a mix of classroom types and office spaces. While more expensive up front, they can pay off in long-term energy savings and dependability.

Chiller and Boiler Systems with Air Handlers

Common in larger or multi-building campuses, these systems allow centralized heating and cooling with distribution through air handlers. They’re reliable and scalable but require more maintenance and space for mechanical rooms.

Systems That May Not Be Ideal

Window or Wall Units

Though still used in portable classrooms or temporary structures, these units don’t provide consistent comfort across a campus and typically lack humidity control and filtration options.

Single-Zone Systems

Schools with only one or two thermostats for the entire building often struggle to maintain comfort in all areas. These systems also waste energy by heating or cooling unused zones.

Equipment Placement and Ductwork Considerations

Space Constraints

Mechanical rooms in older schools may not meet the space or ventilation needs of modern systems. RTUs can help solve this, but only if the roof is structurally suitable.

Duct Access and Routing

Adding or modifying ductwork in existing schools can be difficult due to concrete walls, drop ceilings, or lack of access. Custom duct solutions may be needed during retrofits.

Ventilation Requirements

Schools need a high volume of fresh air, especially in high-use areas like gyms and cafeterias. Systems must be designed to bring in outside air while maintaining temperature and humidity control.

Call a Commercial HVAC Company That Has Worked on Dozens of School, College and University Projects

The ideal HVAC systems for grade schools, high schools and middle schools or college and university campus buildings can vary significantly based on layout, schedule, student body size and a host of other factors.

Top Reasons for Duct Maintenance or Modification in Commercial Buildings

srobertstoms.rev77@gmail.com (Steve Roberts) — Wed, 19 Feb 2025 19:09:08 GMT

Ductwork isn’t the flashiest part of your HVAC system, but it plays a major role in how efficiently and evenly your system can heat or cool your building. In North Texas, where summer heat puts commercial systems through long cycles of operation, even minor duct issues can become expensive problems.

Whether you manage a church, warehouse, office or school in the Arlington area, knowing when to schedule maintenance, or when it's time for more substantial ductwork modification, can help improve comfort and reduce operating costs.

Why Duct Maintenance and Professional Cleaning Matter

Routine duct maintenance and cleaning are some of the easiest ways to protect your HVAC investment. Commercial buildings often have extensive duct networks, and even small inefficiencies can snowball over time.

Airflow and Comfort Issues

While commercial ducts are usually large enough that dust buildup alone won’t restrict airflow, other issues can lead to poor air distribution. Blocked registers, collapsed flex duct sections (if used) or even animals nesting in ductwork can create airflow problems. Maintenance helps catch these issues early and ensures air is reaching all zones of the building evenly.

Better Energy Efficiency

When airflow is restricted or leaks are present, your HVAC system has to work harder to meet demand. Sealing leaks, cleaning ducts and checking connections can reduce strain on your system and lower energy bills.

Longer System Lifespan

Reduced strain means fewer breakdowns and less wear on equipment. Keeping your ductwork clean and sealed helps your system operate closer to its original specifications.

Cleaner Indoor Air

Ducts that accumulate dust, pollen, mold spores or other contaminants can circulate them throughout the building. Periodic cleaning and maintenance helps maintain healthier air quality for employees, tenants or visitors.

When to Schedule Duct Maintenance

Commercial ductwork doesn’t usually need attention every season, but there are key times when it makes sense to schedule service:

After major construction or renovations that may have introduced debris or damaged ducts
If you notice hot or cold spots in the building
When utility bills have risen without a clear cause
At least once every few years, or more often for high-use facilities like schools or manufacturing spaces

Signs It’s Time for Duct Modification or Replacement

Not all duct issues can be solved with maintenance and cleaning . In some cases, especially in older buildings or during system upgrades, ductwork needs to be redesigned, extended or replaced entirely.

Poor System Performance

If your system consistently fails to meet the thermostat setting despite working components, the issue could be with poorly sized or poorly routed ductwork.

A New HVAC System Requires It

Replacing your rooftop unit or installing zoned controls may require a different configuration of ducts to handle airflow properly. Retrofitting new equipment onto old ductwork can cause inefficiencies and noise problems.

Physical Damage

Ducts in warehouses, attics or crawl spaces may be accidentally crushed, torn or disconnected over time. Damaged ducts often need to be replaced to restore performance and airflow.

Outdated Duct Materials

Some older commercial buildings still have ducts made from materials that aren’t up to current efficiency standards—or may be at risk of degradation. Upgrading these ducts can improve both performance and compliance.

Changes in Building Layout

If your floor plan has been modified or repurposed—for example, turning open space into offices—your current ducts may not effectively serve the new design.

Excessive Air Leakage

While some duct leakage is normal, excessive leaks waste energy and reduce system output. If sealing isn’t enough, duct modification or replacement may be the more cost-effective solution.

How to Approach Duct Modifications

If you're considering a duct replacement or redesign, it's important to work with a commercial HVAC company that understands how to balance airflow, pressure and system capacity for large-scale properties.

Unlike residential systems, commercial ductwork must account for longer runs, zoning requirements and heavier operational loads. A full redesign may not always be necessary—but if your building has changed use or your HVAC system has been replaced more than once, it may be worth evaluating how well your ducts match your current setup.

HVAC Units and Best Practices for Regulating Temperatures in Churches and Other Houses of Worship

srobertstoms.rev77@gmail.com (Steve Roberts) — Tue, 18 Feb 2025 18:59:14 GMT

Climate control in churches, synagogues, mosques and other houses of worship presents a unique set of challenges. These spaces are often large, open and architecturally complex, with high ceilings, limited insulation and occupancy levels that fluctuate dramatically from day to day.

Whether you’re managing a traditional church in Arlington or a modern worship facility in the greater DFW area, maintaining comfort while controlling operating costs can be a balancing act.

Challenges of Climate Control in Worship Spaces

Irregular Occupancy

Most houses of worship remain empty for much of the week, only to fill up with hundreds, or even thousands, of attendees during services or events. Systems must be capable of ramping up quickly without wasting energy during low-use periods.

High Ceilings and Large Volumes of Air

Tall sanctuaries and open layouts create thermal stratification, where warm air rises and lingers far above occupied areas. This often requires systems that can deliver high airflow volumes or be supplemented by destratification fans.

Humidity Control

Especially in North Texas, humidity can affect occupant comfort and even damage sensitive interior features like wood pews, instruments or historical fixtures. HVAC systems should include humidity management as part of their overall control strategy.

Acoustic Considerations

Maintaining a quiet environment is essential in worship settings, so selecting HVAC equipment designed for low noise operation is critical. Large churches or facilities that have mechanical rooms typically try to locate them away from the sanctuary and use sound-dampening materials in ductwork to minimize noise intrusion during services.

HVAC Systems That Work Well in Churches

Packaged Rooftop Units (RTUs)

When the building design allows for rooftop access, RTUs are a popular choice. They’re efficient, easy to service and can be configured for zoning and humidity control. However, not all churches have flat or reinforced roofs capable of supporting these units.

Split Systems with Air Handlers

In buildings where rooftop installation isn’t feasible, such as older or architecturally significant churches, split systems with ground-level condensers and indoor air handlers offer more flexibility.

Variable Refrigerant Flow (VRF) Systems

VRF systems are ideal for buildings with multiple zones and varying usage patterns. They provide precise temperature control and energy efficiency but come at a higher upfront cost. They’re often a good fit for churches with classrooms, offices or fellowship halls in addition to the sanctuary.

System Redundancy and Reliability

Given the importance of maintaining a comfortable environment during services and events, incorporating redundancy into HVAC system design can prevent disruptions due to equipment failure. This might involve installing multiple smaller units rather than a single large system, ensuring that if one unit fails, others can maintain adequate climate control.

Systems That May Not Perform as Well

Single-Zone Systems

While cost-effective up front, single-zone systems are rarely ideal for worship spaces due to their lack of flexibility. Cooling an entire building just to condition a small office or classroom during off-hours can waste significant energy.

Window or Portable Units

Window or portable air conditioners are rarely adequate for permanent use in large worship spaces. They offer limited coverage and create hot/cold spots, and most aren't powerful enough for larger volumes of air. However, using a mini-split or ductless heat pump for offices, classrooms or separate structures on the property may be an effective way to enhance zone control and save money on overall energy costs.

Placement Considerations

Roof Constraints

Many older or ornate churches have pitched roofs, steeples or unsupported structures that make rooftop unit installation impractical. In those cases, equipment must be installed at ground level or in mechanical rooms, which may be limited in size or access.

Noise Management

Sanctuary acoustics matter. Equipment placement should avoid creating noise that could interrupt services, music, or spoken word. This may require locating equipment away from the main sanctuary or using insulated ducting.

Ductwork Design Challenges

Long Runs and Airflow Loss

Large buildings with minimal interior walls often require long duct runs, which can result in pressure loss. Proper sizing, sealing and possibly booster fans may be needed to maintain airflow across the space.

Limited Interior Access

In historic or architecturally protected buildings, retrofitting new ductwork can be difficult without compromising aesthetics. These projects often require custom solutions and creative routing to preserve the look of the space.

What Is the Proper Humidity Level to Prevent Mold, Equipment Damage and Discomfort?

srobertstoms.rev77@gmail.com (Steve Roberts) — Tue, 11 Feb 2025 18:51:22 GMT

Maintaining the right indoor humidity isn’t just about comfort—it plays a major role in preserving your building materials, protecting equipment and preventing bacteria growth. For commercial buildings in North Texas, where outdoor humidity can swing drastically, effective humidity control is essential.

Recommended Humidity Levels for Commercial Spaces

The general consensus among HVAC professionals is that indoor relative humidity should stay between 40% and 60%. Below 40%, the air becomes too dry, which can cause issues like static electricity, skin and eye irritation and damage to sensitive electronics or wood surfaces. Above 60%, conditions become favorable for bacteria, mildew and dust mites, and air may start to feel damp or stuffy.

Why Humidity Control Matters in Commercial Settings

Equipment Protection

In schools, offices and data-heavy environments, too much humidity can corrode sensitive electronics or cause paper products and packaging to degrade. In industrial settings, high humidity can also affect machinery performance.

Occupant Comfort and Productivity

Humid air can make indoor temperatures feel warmer than they are, leading to overcooling and discomfort. On the other hand, dry air can cause skin irritation and increase the spread of airborne particles. Maintaining a balanced humidity range helps support productivity and wellness.

Do Different Commercial Spaces Need Different Humidity Levels?

Data Centers and Server Rooms

These typically require humidity between 45-55% to prevent static discharge (from dry air) or condensation (from excessive humidity), both of which can damage equipment.

Healthcare Facilities

Hospitals and clinics often target 45-60% humidity to help prevent airborne pathogens while maintaining patient comfort and material integrity.

Museums or Archives

Humidity should often be kept below 50% to preserve artwork, documents and delicate materials. Even slight fluctuations can damage artifacts over time.

Gyms and Locker Rooms

These areas often face elevated humidity due to heavy perspiration during workouts, high foot traffic and steam generated from showers and wet surfaces.

Aggressive humidity control—often targeting 40–50%—can help prevent odor and mildew buildup.

Manufacturing Facilities

Depending on the materials involved, humidity targets may vary. Woodworking, printing and electronics manufacturing often have tighter control ranges to prevent material or equipment damage.

Built-In Humidity Control Features in Modern Commercial HVAC Units

Variable-Speed Fans

Slower fan speeds during low-load conditions allow the system more time to remove moisture during cooling cycles.

Hot Gas Reheat or Reheat Coils

These systems remove moisture from the air, then reheat it slightly to avoid overcooling—especially useful in humid climates like North Texas.

Demand-Controlled Ventilation

This system adjusts fresh air intake based on CO₂ levels or occupancy, which can help avoid introducing too much outdoor humidity unnecessarily.

Integrated Dehumidification Modes

Some packaged units and VRF systems have built-in dehumidification capabilities, ideal for spaces like schools or mixed-use commercial buildings.

When Is a Separate Dehumidifier Necessary?

In most commercial settings, a properly sized HVAC system with built-in humidity controls is sufficient. However, standalone dehumidifiers may be necessary when:

The space sees extreme moisture loads, such as gymnasiums, pool areas or commercial kitchens
The existing HVAC system is outdated or oversized and short-cycles without removing enough moisture
There’s a specific humidity-sensitive use case, such as archives, manufacturing processes or server rooms

The best commercial dehumidifier in these edge cases will depend on the size of the space and the unique factors that make humidity control a challenge. Some of the common options include:

Ducted dehumidifiers, which integrate with existing HVAC ductwork
Standalone portable units, typically used for isolated areas
Desiccant dehumidifiers, which may be used in industrial or specialized environments requiring low-humidity conditions

Find Out if a More Robust Dehumidification Solution Is Needed in Your Commercial Building

In Arlington, Fort Worth and Dallas commercial buildings, regulating temperature without managing humidity is only doing half the job. Whether you’re trying to protect electronics, maintain air quality or just keep your building comfortable through another Texas summer, proper humidity control is essential.

What Is VRF Technology and Is It Right for My Facility?

srobertstoms.rev77@gmail.com (Steve Roberts) — Wed, 29 Jan 2025 20:03:33 GMT

When it comes to heating and cooling commercial buildings, variable refrigerant flow (VRF) technology is gaining popularity as a highly efficient and customizable solution. But how does VRF work, and is it the right fit for your facility?

How VRF Technology Works

VRF systems use a network of refrigerant lines to deliver heating and cooling simultaneously across different zones in a building. Unlike traditional HVAC systems that operate at a fixed capacity, VRF units can adjust the amount of refrigerant sent to each indoor unit based on demand, making them more energy-efficient.

There are two main types of VRF systems:

Heat Pump VRF – Provides either heating or cooling to all zones at one time, making it ideal for open-concept offices or spaces with similar temperature needs.
Heat Recovery VRF – Allows simultaneous heating and cooling in different zones, which is beneficial for buildings with varying temperature demands, such as hotels, schools or multi-tenant office spaces.

By modulating refrigerant flow and using inverter-driven compressors, VRF systems minimize energy waste and provide more precise temperature control than traditional systems.

Benefits of VRF Technology

Energy Savings – VRF systems only use the necessary amount of energy to meet demand, reducing utility costs compared to conventional HVAC systems.
Zoned Comfort Control – The ability to heat and cool different areas independently improves occupant comfort, which is particularly useful for large facilities with diverse temperature needs.
Compact and Flexible Design – With no need for extensive ductwork, VRF systems are ideal for buildings where space is limited or retrofitting is required.
Quiet Operation – VRF units operate at lower noise levels than traditional rooftop or split systems, creating a more comfortable indoor environment.
Longevity and Low Maintenance – Because they operate at variable speeds instead of frequently cycling on and off, VRF systems experience less wear and tear, leading to a longer lifespan.

Potential Drawbacks of VRF Systems

Higher Initial Cost

The upfront installation costs for VRF systems can be higher than conventional HVAC systems, though energy savings may offset the investment over time. However, this is highly dependent on the cost of an alternative HVAC replacement solution . If your building only needs a single higher cost VRF system instead of two separate HVAC units, VRF might deliver better performance while coming in at a lower cost.

Complex Installation

Proper design and installation require expertise, as incorrect setup can lead to inefficiencies and performance issues. If you are considering a VRF system, it’s important to work with a commercial HVAC company that understands this technology and how to maximize the benefits.

Limited Capacity for Extreme Climates

In areas with extremely cold temperatures, VRF heat pumps may struggle to provide sufficient heating without additional backup systems. That being said, the typically mild winters of Arlington make these systems relatively popular among property owners and facility managers in our area.

Is VRF Right for Your Facility?

The decision to install a VRF system depends on several factors, including building size, usage patterns and budget considerations. Facilities that can benefit the most from VRF include:

Office buildings – Zoned control enhances comfort in meeting rooms, open areas and private offices.
Hotels and multi-tenant spaces – Different temperature preferences can be accommodated without affecting other rooms.
Healthcare facilities – Precise climate control ensures patient comfort while reducing energy waste.
Retail stores and restaurants – VRF’s efficiency helps maintain a comfortable environment even with frequent temperature fluctuations from doors opening and closing.

For large industrial facilities or buildings with extreme temperature demands, a combination of VRF and supplemental heating or cooling systems may be necessary to achieve optimal performance.

The Impact of Poor Air Quality on Your Employees

srobertstoms.rev77@gmail.com (Steve Roberts) — Wed, 22 Jan 2025 19:48:55 GMT

Indoor air quality plays a critical role in workplace health, yet it’s often overlooked until problems arise. Poor air quality doesn’t just affect comfort—it can lead to serious health issues, reduced productivity and increased absenteeism. If your building has persistent air quality problems, it could be costing your business more than you realize.

Health Issues Caused by Poor Air Quality

When employees breathe in polluted indoor air, they may experience both short-term and long-term health effects. Symptoms such as headaches, dizziness, fatigue and irritation of the eyes, nose or throat are common in environments with poor ventilation or airborne contaminants.

Long-term exposure to polluted indoor air can contribute to more severe conditions like respiratory diseases, cardiovascular problems and worsened allergies.

One of the biggest culprits of poor air quality in office settings is volatile organic compounds (VOCs), which are emitted from cleaning products, office furniture and even printers. Mold, dust and poor ventilation can also exacerbate respiratory issues, particularly if HVAC systems aren’t adequately filtering the air being circulated inside a facility.

Employees with pre-existing conditions like asthma are particularly vulnerable. Even minor air quality problems can significantly impact their ability to work comfortably and be productive.

Decreased Productivity and Cognitive Function

Studies show that poor air quality directly impacts an employee’s ability to concentrate and perform tasks efficiently. When air contains high levels of carbon dioxide (CO₂) or other pollutants, cognitive function declines, leading to slower response times, reduced problem-solving skills and increased errors.

A Harvard study found that employees in well-ventilated workplaces with lower CO₂ levels perform better on cognitive tests than those in buildings with poor ventilation. If your employees seem more sluggish or unfocused than usual, air quality could be a hidden factor affecting their productivity.

Higher Absenteeism and Sick Building Syndrome

If employees are frequently calling in sick, poor air quality could be playing a role. Exposure to pollutants and allergens increases the likelihood of developing respiratory infections and worsening chronic conditions like asthma or sinus issues.

Sick Building Syndrome (SBS) isn’t just an HVAC buzzword—it’s an actual phenomenon. Employees who experience persistent symptoms—such as headaches, dry cough, skin irritation or difficulty concentrating—while in the office but feel better when they leave may be suffering from SBS.

This often occurs in buildings with poor ventilation, excessive dust or mold growth. Over time, high absenteeism rates due to these conditions can disrupt business operations and increase healthcare costs for employers.

How to Identify Air Quality Problems

Not all air quality issues are immediately obvious. Facility managers and business owners can look for key warning signs that indicate a problem:

Employee Complaints – If multiple employees report similar symptoms (fatigue, headaches, respiratory issues), air quality could be a common denominator.
Stale or Stuffy Air – A lack of fresh airflow suggests poor ventilation, which can cause CO₂ levels to rise.
Visible Mold or Water Damage – Damp areas and musty odors are clear indicators of mold growth, which can release harmful spores into the air.
F requent HVAC Issues – If your HVAC system struggles to regulate temperature or airflow, it may not be filtering air effectively.

The Business Costs of Ignoring Air Quality

Beyond health concerns, poor indoor air quality can have a direct financial impact. Businesses with ongoing air quality problems often experience higher turnover rates, as employees are less likely to stay in an environment that negatively affects their well-being. Additionally, companies may face legal liability if hazardous indoor air is found to be causing chronic illnesses among staff.

Energy efficiency is another factor. An overworked HVAC system that struggles to filter and circulate air will consume more energy, leading to higher utility bills. Addressing air quality concerns not only benefits employees but also reduces long-term operational costs.

Improving Workplace Air Quality

The good news is that improving indoor air quality doesn’t always require expensive overhauls. Here are some steps businesses can take:

Upgrade HVAC Filters – High-efficiency filters (such as HEPA or MERV-13) can capture finer particles and pollutants, improving air circulation.
Increase Ventilation – Opening windows when possible or using air purifiers can help introduce fresh air and reduce pollutant buildup.
Control Humidity Levels – Keeping indoor humidity between 30 percent and 50 percent prevents mold growth and dust mite infestations.
Use Low-VOC Materials – Opt for office furniture, paint and cleaning products that emit fewer chemicals into the air.
Schedule Regular HVAC Maintenance – Ensuring ducts are clean and filters are replaced regularly prevents the buildup of airborne contaminants.

How to Tell If Your Commercial HVAC Unit Is Working Properly

srobertstoms.rev77@gmail.com (Steve Roberts) — Wed, 08 Jan 2025 19:35:06 GMT

For building and facility managers, ensuring a commercial HVAC system runs efficiently is crucial for maintaining comfort, air quality and energy efficiency. You can identify and address issues more quickly and prevent serious damage by watching out for any changes in the system’s operation and performance.

Listen for Unusual Noises

A well-functioning HVAC system should run relatively quietly, producing only the sound of air flowing through the vents and the occasional hum of the unit cycling. New or unusual noises can indicate problems, such as:

Banging or clanking – Could mean loose or broken components in the blower or compressor.
Grinding or screeching – Often a sign of motor issues or worn-out bearings.
Whistling or hissing – May indicate duct leaks or a refrigerant leak.
Repeated clicking – Could signal electrical problems with relays or capacitors.

If you notice persistent or unusual sounds, scheduling an inspection can prevent minor issues from escalating into costly repairs.

Feel for Proper Airflow and Temperature

An HVAC system should provide consistent airflow and maintain the set temperature throughout the facility. Signs of trouble include:

Uneven heating or cooling – Hot and cold spots suggest airflow problems, duct leaks or thermostat issues.
Weak airflow from vents – Could be due to clogged filters, blocked ducts or a failing blower motor.
Humidity problems – If the building feels excessively humid, the system may not be dehumidifying properly, which can lead to mold growth and discomfort.

Look for Visible Warning Signs on Your HVAC Equipment

Watch for ice buildup on coils, which may indicate low refrigerant levels or airflow restrictions.
Excess condensation or pooling water near the unit can point to a clogged drain line or a failing condensate pump.
Additionally, dirty or clogged filters can restrict airflow, forcing the system to work harder and reducing indoor air quality.
Frequent tripped breakers or sudden system shutdowns could suggest electrical overloads or compressor issues.

If any of these warning signs appear, immediate attention is necessary to prevent costly repairs.

Investigate Strange Odors

Strange smells coming from your HVAC system can be an early indicator of underlying issues. Some odors are harmless, but others can point to serious mechanical or air quality concerns:

Burning or electrical smells – If you detect a burning odor, it could mean overheating components, such as a motor or wiring issue. A persistent electrical smell may indicate that the unit is drawing too much power or that its wiring insultation is failing.
Musty or moldy odors – This often signals excess moisture buildup in the ductwork, air handler or drip pans, which can lead to mold and mildew growth. Poor drainage or clogged filters can exacerbate the issue.
Rotten egg or sulfur-like smell – This is a major red flag, as it could indicate a natural gas leak. If this odor is present, evacuate the building immediately and contact a professional.
Chemical or refrigerant smells – A sweet, ether-like smell may mean a refrigerant leak, which can impact system efficiency and pose health risks.

If you notice persistent or strong odors, it’s best to shut down the unit and schedule an inspection to pinpoint the cause before the issue worsens.

Monitor System Cycling

Workers who spend a significant amount of time in a commercial structure will inevitably become acclimated to its rhythms, including the sounds of the HVAC system cycling. If those cycling patterns suddenly change, despite no changes to thermostat settings or outdoor temperature, it may indicate underlying problems:

Short cycling (turning on and off too frequently) – This can indicate issues such as a dirty air filter, thermostat malfunctions, refrigerant leaks, or an oversized unit. Short cycling forces the system to work harder, increasing energy costs and wear on components.
Long run times – If your system runs much longer than usual without shutting off, it may be struggling to reach the set temperature. This could be caused by a clogged filter, leaky ductwork, low refrigerant or a failing compressor.
System failing to turn on – If the unit doesn’t start when expected, it could be due to thermostat failures, tripped breakers, or an issue with the capacitor or ignition system.

Inspect Outdoor Components

Many HVAC problems originate outside, where the condenser unit and other external parts are exposed to dirt, debris, and weather-related wear. Facility managers should regularly check the outdoor unit for any blockages caused by leaves, dirt or other debris, as restricted airflow can cause the system to overheat. Adequate clearance around the unit is necessary for proper ventilation.

The condenser coils should also be inspected for damage or corrosion, as bent or dirty coils can impact efficiency. If you find standing water around the unit, it could indicate drainage issues or refrigerant leaks.

Routine visual inspections can help catch small issues before they turn into major system failures, ensuring reliable performance and a longer lifespan for your commercial HVAC unit.

Monitor Energy Usage and Thermostat Performance

An unexpected spike in energy costs could signal HVAC inefficiencies. If a building’s energy bills are climbing despite normal usage, the system may be running harder than necessary due to dirty components, refrigerant issues or duct leaks.

The first thing you should check after noticing unusual changes in your energy bills is the building’s thermostat. If there’s a noticeable discrepancy between the actual temperature inside and the temperature set on the thermostat, it may require recalibration or replacement.

Regularly monitoring energy consumption and thermostat performance can help facility managers spot inefficiencies before they result in higher operational costs.

When to Schedule Professional Commercial HVAC Maintenance

Regular maintenance can prevent most HVAC issues before they impact comfort or efficiency. If you notice any of the above warning signs, a professional HVAC technician can inspect the system, diagnose the issue, and recommend necessary repairs or adjustments.

By keeping an eye (and ear) on these key indicators, facility managers can ensure their commercial HVAC systems remain in top condition, reducing downtime and costly emergency repairs. Call Tom’s Commercial at 817-857-7400 if you suspect any problems with your system.

If neglected, commercial systems can consume excessive energy, fail prematurely or cause costly disruptions to your business.

Conduct Regular Inspections

Routine inspections are the cornerstone of a well-maintained HVAC system. Professional technicians should examine the unit at least twice a year—before the heating and cooling seasons—to identify any issues early. Inspections typically include checking for wear and tear, loose connections, unusual noises and proper system operation. Early detection of problems can save significant time and money in future repairs.

Clean or Replace Air Filters Frequently

Dirty or clogged filters force the HVAC system to work harder, leading to reduced efficiency and increased energy costs. Commercial HVAC systems often have multiple filters across different zones or components, depending on the size and configuration of the building. In these settings, where systems frequently run continuously, filters should be checked monthly and replaced or cleaned as needed. Clean filters improve airflow, maintain indoor air quality and prevent strain on the unit’s components.

Keep Coils Clean

Evaporator and condenser coils can accumulate dirt and debris over time, reducing their ability to absorb and release heat. This buildup can force the system to work harder, increasing energy consumption. A reliable maintenance company will inspect the coils during routine visits and recommend or perform cleaning as needed to ensure the system runs efficiently and effectively.

Check Thermostat Settings

Improper thermostat settings can lead to inconsistent temperatures, energy waste and unhappy employees or customers. Commercial HVAC maintenance professionals should always check your thermostats to ensure they are calibrated correctly and programmed for the building’s occupancy patterns. If you haven’t already, you may want to consider upgrading to smart or programmable thermostats for better control and energy savings.

Inspect and Seal Ductwork

Leaky or poorly insulated ducts can significantly reduce system efficiency by allowing conditioned air to escape. Ducts should be periodically inspected for gaps, cracks or loose connections. Commercial HVAC maintenance and repair technicians should be proactively sealing any duct issues in your building with high-quality duct tape or mastic. Proper insulation further enhances efficiency, particularly in areas where ductwork is exposed to extreme temperatures.

Monitor Refrigerant Levels

Low refrigerant levels can compromise your system’s cooling capacity and lead to higher energy consumption. Technicians should check refrigerant levels during routine maintenance, address any leaks and ensure the system is charged to the manufacturer’s specifications. This will optimize performance and help prevent further damage.

Lubricate Moving Parts

Commercial HVAC systems have numerous moving components, such as motors, belts and fans. Without proper lubrication, these parts can wear out prematurely or cause the system to overheat. Regular lubrication reduces friction, promotes smooth operation and extends the life of the components.

Test and Inspect Electrical Connections

Faulty electrical connections can cause system failures and pose safety risks. Technicians should inspect and tighten all connections, test voltage levels and see that the electrical components are in good working condition. This step reduces the risk of unexpected breakdowns and prolongs the system’s lifespan.

Perform Regular Drain Line Maintenance

Drain lines are responsible for removing moisture collected during the cooling process. Over time, algae, mold or debris can clog these lines, leading to water leaks and potential damage to your property.

Schedule Preventive Maintenance Contracts

One of the best ways to ensure your commercial HVAC unit stays in peak condition is by signing a preventive maintenance contract with a trusted HVAC service provider.

What It Means When Your Commercial HVAC Unit is “Short Cycling”

srobertstoms.rev77@gmail.com (Steve Roberts) — Wed, 20 Nov 2024 19:54:34 GMT

Maintaining a comfortable, energy-efficient environment is essential for any commercial space.

When your commercial heating or cooling system begins to short-cycle, it can lead to uncomfortable indoor conditions, increase energy bills and even cause premature equipment failure.

What Is Short Cycling?

Short cycling occurs when an HVAC system switches on and off in fast succession without reaching the desired temperature or completing its full heating or cooling cycle. Instead of running long enough at properly spaced intervals to maintain stable temperatures, the system shuts off after a brief period and then restarts shortly afterward. This can happen with both heating and cooling cycles, making it a year-round issue in commercial buildings with improperly sized units, thermostat problems or other maintenance issues.

In commercial settings, where HVAC systems often need to control temperatures over large areas or multiple zones, short cycling is particularly problematic. Not only does the system fail to adequately heat or cool the space, but it also puts a strain on HVAC components, potentially leading to costly repairs or replacements.

Causes of Short Cycling in Commercial HVAC Units

Several common issues can lead to short cycling in commercial HVAC systems. Identifying the root cause can help prevent further damage and ensure efficient operation.

Oversized or Undersized HVAC Unit

One of the primary causes of short cycling is an improperly sized HVAC system. When an HVAC system is too large for the space, it cools or heats the area very quickly. This rapid cycling leads to uneven temperature distribution and inadequate dehumidification (in cooling mode). The thermostat detects the temperature fluctuations and signals the unit to turn back on after a short interval.

Conversely, an undersized unit will also short cycle, as it cannot adequately handle the load and continuously restarts as it struggles to reach and maintain the desired temperature. For commercial spaces, accurate load calculations are necessary to determine the right system size.

Faulty or Improperly Located Thermostat

The thermostat plays a critical role in temperature regulation, but issues with the thermostat can easily lead to short cycling. If the thermostat is faulty, improperly calibrated or located in an area with temperature fluctuations (such as near a drafty door or window), it may send incorrect signals to the HVAC system.

In a commercial setting, where consistent temperature regulation is essential, incorrect thermostat readings can create significant discomfort and inefficiency.

Dirty or Clogged Air Filters

Air filters are designed to trap dust, debris and other airborne particles, but if they’re not cleaned or replaced regularly, they can restrict airflow. When airflow is limited, the HVAC system has to work harder to push air through, leading to overheating and shutdown.

This cycle of overheating and restarting can cause short cycling, increased energy consumption and decreased indoor air quality.

Low Refrigerant Levels

The compressor can overheat in commercial air conditioners with low refrigerant levels, leading to short cycling. This is often due to a leak, which means that not only does the system lose refrigerant, but it also fails to cool the air effectively.

Low refrigerant levels are a serious issue that can damage the compressor, so it’s crucial to have any leaks addressed by a licensed HVAC technician.

Blocked or Leaky Air Ducts

In a commercial space, blocked or damaged air ducts can significantly affect airflow, leading to imbalances and short cycling. Ductwork obstructions or leaks force the system to compensate, creating pressure imbalances that can lead to overheating. Damaged or leaky ductwork should be repaired quickly and vents and registers should be free of obstructions to prevent airflow issues that can lead to short cycling.

The Impact of Short Cycling on Your HVAC System

Increased Energy Costs : Each time the HVAC unit powers on, it draws a large amount of energy. Frequent cycling results in higher energy usage and increased utility bills, which can be costly for commercial properties.
Wear and Tear on Components : Frequent on-and-off cycling places significant stress on key components like the compressor, fan motor and electrical controls. This wear and tear can lead to costly repairs and ultimately reduce the lifespan of your HVAC system.
Reduced Comfort and Air Quality : Short cycling doesn’t allow the system to maintain consistent indoor temperatures, which can create uncomfortable conditions for employees, clients and tenants. It also prevents the system from dehumidifying the air effectively, which can lead to higher humidity levels and diminished indoor air quality.

Solutions to Address and Prevent Short Cycling

Schedule Routine Maintenance

Regular maintenance is key to preventing issues that lead to short cycling. A maintenance check can catch issues like clogged filters, low refrigerant levels and faulty thermostats before they escalate. In commercial settings, routine maintenance is especially crucial due to the higher operational demands placed on the HVAC system.

Proper System Sizing

If your system is oversized or undersized, upgrading to a properly sized unit may be necessary to avoid short cycling. A qualified HVAC contractor can perform a load calculation to determine the correct unit size for your commercial space, ensuring the system you install can operate efficiently.

Replace or Clean Air Filters

Regularly replacing or cleaning air filters can prevent airflow restrictions and keep the system from overheating. For commercial spaces with high usage, air filters should be checked more frequently to prevent clogs.

Inspect and Repair Ductwork

Ductwork issues can easily lead to short cycling, as restricted or leaky ducts put a strain on the system. During regularly scheduled inspections, a commercial HVAC technician can check vents to ensure they are clear and inspect ducts for leaks that might be compromising proper air distribution and balanced flow.

Upgrade Your Thermostat

If thermostat issues are causing short cycling, consider upgrading to a programmable or smart thermostat. These thermostats offer greater precision and can help reduce unnecessary cycling by allowing better control over temperature settings.

Cold and Hot Temperature Spots in Your Commercial Space: Causes, Effects and Solutions

srobertstoms.rev77@gmail.com (Steve Roberts) — Fri, 15 Nov 2024 19:46:14 GMT

Commercial spaces, whether they are offices, stores or industrial facilities, must maintain a comfortable environment for employees, customers and visitors. Yet, many buildings struggle with inconsistent temperatures, leading to cold or hot spots in specific areas.

These temperature imbalances can affect both productivity and comfort, potentially even driving up energy costs.

Common Causes of Temperature Imbalances in Commercial Spaces

Poor HVAC Design or Installation

One of the primary causes of hot and cold spots is an improperly designed or installed HVAC (heating, ventilation and air conditioning) system. If the HVAC system doesn’t circulate air evenly or is too small for the building’s size, certain areas will not receive adequate heating or cooling, leading to discomfort in those zones.

Airflow Blockages

Over time, vents, filters or ductwork can become clogged with dust and debris, obstructing airflow and causing temperature irregularities. Furniture or equipment placed too close to vents can also prevent air from circulating properly, resulting in certain areas feeling colder or hotter than others.

Building Orientation and Window Placement

Sun exposure and building layout significantly influence temperature balance. Offices on the south side of a building may receive more sunlight, making them warmer, while those on the north side may be colder. Large windows without adequate shades can exacerbate these hot or cold spots, as sunlight heats certain areas more than others.

Faulty Thermostats

Inaccurate or malfunctioning thermostats can lead to uneven temperatures in a commercial space. If a thermostat isn’t calibrated correctly, it may not reflect the true temperature of the area it’s controlling, causing some sections of the building to become excessively warm or cool.

Insulation Issues

Poor insulation is another major factor in temperature discrepancies. Older buildings may lack proper insulation, and even newer buildings may have areas where insulation is inadequate or has deteriorated.

In these cases, heat can escape during winter, and excess warmth can enter during summer, leading to uneven temperatures in different parts of the building.

Effects of Hot and Cold Spots on Your Business

While minor temperature fluctuations may not seem like a major issue, persistent hot and cold spots can negatively impact employee morale and productivity and leave customers or visitors with a negative impression of your business.

Reduced Employee Comfort and Productivity

An uncomfortable work environment can lead to reduced productivity and job satisfaction. When employees are too hot or too cold, they’re more likely to be distracted, fatigued or less motivated to work. Temperature-related discomfort can also lead to increased absenteeism and even employee turnover.

Higher Energy Bills

An imbalanced HVAC system often consumes more energy as it works harder to maintain the temperature set on thermostats in the building.

Over time, this can lead to higher utility bills. A properly balanced system is more energy-efficient, which helps lower costs while maintaining a comfortable environment.

Potential Equipment Damage

Extreme temperature variations can impact the longevity and performance of equipment. For instance, server rooms need consistent cooling to avoid overheating. Temperature-sensitive equipment that is exposed to constant temperature fluctuations may also experience accelerated wear and tear, increasing maintenance and replacement costs and downtime.

Customer Discomfort

An uncomfortable indoor environment can negatively affect the customer experience and their impression of your business. For companies in retail or hospitality, customer satisfaction is necessary for retention, and hot or cold spots can deter repeat visits.

Solutions for Eliminating Temperature Imbalances

Upgrade or Repair the HVAC System

One of the first steps in resolving temperature inconsistencies is making sure that your HVAC system is appropriately sized and functioning optimally. An HVAC professional can inspect the system for any design flaws, perform repairs if necessary and recommend upgrades or modifications to improve efficiency.

Install Zoned Heating and Cooling

Zoning allows you to divide a building into different sections, each with its own thermostat. The temperature in each zone can be adjusted independently, offering greater control over heating and cooling based on each space’s unique needs. This solution is particularly effective in large commercial spaces with diverse temperature requirements.

Proper Insulation and Sealing

Improving insulation, especially in older buildings, is an effective way to prevent hot and cold spots. Insulating walls, ceilings and floors, and sealing windows and doors properly, can help prevent temperature fluctuations caused by drafts or leaks.

Regular Maintenance and Cleaning

Routine HVAC maintenance is essential for optimal airflow and performance. Changing filters regularly, cleaning ducts and inspecting vents for blockages will help maintain consistent air distribution and reduce the risk of hot and cold spots developing.

Smart Thermostats and Climate Controls

Smart thermostats can be programmed to maintain specific temperatures throughout the day, adjusting based on occupancy and time. These thermostats can also detect and compensate for areas that require more heating or cooling, making them a valuable tool in managing temperature variations in commercial spaces.

Window Treatments and Sunshades

Installing blinds, sunshades or reflective window films can help minimize temperature fluctuations caused by direct sunlight. This is especially important in areas with large windows or southern exposure, where sun heat gain can lead to uncomfortable hot spots.

Indoor Air Quality Issues Found in Commercial Spaces of Business

srobertstoms.rev77@gmail.com (Steve Roberts) — Thu, 24 Oct 2024 20:06:59 GMT

Indoor air quality (IAQ) is a critical aspect of maintaining a safe, comfortable and productive environment in commercial spaces.

Poor air quality can lead to a range of problems, from minor health irritations like headaches and allergies to more severe issues such as respiratory conditions or chronic fatigue.

Unique IAQ Concerns in Different Commercial Spaces

Restaurants

Restaurants face unique air quality challenges due to the presence of cooking exhaust, grease, smoke and high humidity levels from kitchen activities. Without proper ventilation, these pollutants can spread throughout the space, creating an unhealthy environment for employees and patrons alike. Excess humidity from steam and cooking can also contribute to mold growth, especially in poorly ventilated areas, leading to both health concerns and structural damage.

In addition to health risks, these pollutants can affect the overall dining experience, leaving lingering odors and creating an uncomfortable environment for customers.

Manufacturing Facilities

Manufacturing facilities present a different set of challenges, including chemical fumes, dust and particulate matter that can degrade air quality and pose serious health risks to workers. Depending on the type of manufacturing, these facilities may deal with a variety of pollutants such as volatile organic compounds (VOCs), fumes from paints and solvents, particulate matter generated by manufacturing processes, or hazardous materials like asbestos.

Workers in these environments are at risk of exposure to harmful chemicals and fine particles that can cause respiratory problems or even long-term health issues like chronic lung disease.

Office Spaces

Office spaces might not have the obvious air quality concerns of restaurants or manufacturing facilities, but they still face significant IAQ challenges. One of the main issues in office environments is the presence of volatile organic compounds (VOCs) emitted from office equipment, furniture, carpeting and cleaning supplies. These chemicals can lead to headaches, dizziness and other symptoms that affect employee productivity and well-being.

Office spaces can also accumulate dust and allergens at a rapid rate, especially in older buildings with outdated HVAC systems or poor ventilation.

Schools

Schools are another type of commercial space that can face a wide range of indoor air quality issues. Dust, mold and allergens can build up in classrooms and common areas, especially in older buildings with inadequate ventilation systems. Poor indoor air quality in schools can have a particularly severe impact on children, as they are more susceptible to respiratory issues and other health problems. Schools may also have high concentrations of VOCs from cleaning supplies, paint and furnishings, which can further exacerbate underlying health issues in building occupants.

Poor ventilation in crowded classrooms can also lead to the buildup of carbon dioxide, which can make students feel drowsy or less focused. Regular maintenance of HVAC systems, along with the use of air purifiers and other IAQ technologies, can allow air to cycle quickly and help keep air quality in check.

IAQ Technologies for Commercial Properties

Advanced Filtration Systems

One of the most critical components of maintaining good indoor air quality is ensuring that HVAC systems are equipped with high-quality filters. Commercial facilities with strict IAQ standards often rely on HEPA (High-Efficiency Particulate Air) filters, which are capable of capturing 99.97% of particles as small as 0.3 microns. These filters are effective at removing dust, allergens, and other airborne pollutants that can degrade air quality.

Businesses may also leverage activated carbon filters to absorb chemical fumes and VOCs, providing an added layer of protection for workers.

Ventilation Systems

Proper ventilation is essential for removing pollutants and ensuring a steady supply of fresh air. In restaurants and manufacturing spaces, powerful exhaust systems are necessary to remove cooking fumes, smoke and particulate matter from the air. Similarly, offices and schools benefit from proper ventilation systems that prevent the buildup of indoor pollutants like VOCs, dust and carbon dioxide.

UV-C Light Systems

Ultraviolet (UV-C) light systems are another technology that can help improve indoor air quality in commercial spaces, particularly in environments where mold and bacteria are common concerns. UV-C light can be installed within ductwork or near evaporator coils to disinfect air as it circulates, killing mold spores, bacteria and viruses that can degrade air quality.

These systems are particularly beneficial in schools, healthcare facilities and high-traffic areas where maintaining clean, healthy air is crucial.

Air Purifiers

Standalone air purifiers equipped with HEPA and activated carbon filters can be used in offices, schools and other commercial spaces to supplement existing HVAC systems. These purifiers can be strategically placed in areas where pollutants tend to accumulate, such as high-traffic zones.

Humidity Control Systems

Humidity control is crucial in commercial spaces like restaurants and schools where high moisture levels can contribute to mold growth and other IAQ issues. Dehumidifiers and humidity control systems can help maintain balanced moisture levels, preventing mold from developing and keeping the air comfortable and healthy.

What It Means When a Commercial Heating System Blows Cool Air Instead of Hot

srobertstoms.rev77@gmail.com (Steve Roberts) — Thu, 17 Oct 2024 20:02:31 GMT

Commercial heating systems play a vital role in maintaining comfort and productivity in office buildings, manufacturing facilities, retail spaces and other business environments. Heating failures can disrupt operations, make workers and customers uncomfortable, and potentially reduce productivity.

Heating problems can vary in severity and have a range of root causes. The issues that cause a furnace or commercial heating system to circulate lukewarm air may be different than the problems that cause it to blow cold air.

Commercial HVAC systems are inherently complex, and it typically requires in-depth diagnostics performed by experienced technicians to accurately pinpoint the cause of a heating failure and develop a long-term solution.

Thermostat Issues

One of the most straightforward reasons why a commercial heating system may blow cool air is a faulty thermostat. In commercial buildings, thermostats are often more advanced than those found in homes, and they may control multiple zones or interact with other building management systems (BMS). If the thermostat is not set correctly, or if it's malfunctioning, it could send the wrong signal to the heating system.

Common thermostat-related issues include:

Incorrect settings, such as the thermostat being set to “cool” instead of “heat” mode.
Programming errors, especially in systems that have complex schedules for different zones or times of day.
Calibration issues, where the thermostat isn’t accurately measuring the room temperature.
Thermostat malfunctions due to old age, wiring issues or connectivity problems in smart thermostats or BMS-integrated devices.

Verify that the thermostat is set to "heat" mode and that the desired temperature is higher than the current room temperature. If the thermostat appears to be malfunctioning, it may need to be recalibrated or replaced by a commercial HVAC technician.

Airflow Restrictions or Blockages

Another common issue in commercial heating systems is restricted airflow. These systems are often larger and more complex than residential units, so airflow problems can arise in multiple areas, from ductwork damage or blocked registers to dirty filters.

Possible airflow problems include:

Clogged air filters, which are especially common in commercial environments where air pollutants and debris can build up quickly.
Blocked or closed air registers or vents, which can prevent the warm air from circulating effectively.
Damaged or obstructed ductwork.

Insufficient Fuel Supply

In commercial buildings that use gas or oil-fired heating systems, an insufficient fuel supply could be the reason the heating system is blowing cool air. Without enough fuel, the burners won’t be able to generate enough heat to warm the air, resulting in cool air being circulated instead.

Common causes of insufficient fuel supply include:

Gas line issues, such as leaks, blockages or low pressure.
Oil tank running low or out of fuel.
Faulty gas valves that fail to open properly, preventing fuel from reaching the burners.

If supply isn’t an issue, an experienced commercial HVAC technician should be able to diagnose and resolve the problem.

Burner or Ignition Failure

For commercial heating systems that rely on burners or ignition systems to generate heat, a failure in these components can result in cool air being blown instead of warm air. This issue is particularly common in older systems, where wear and tear can cause the burners to malfunction or the ignition system to fail.

Causes of burner or ignition failure include:

Dirty burners, which can cause incomplete combustion and reduce heat generation.
A faulty ignition system, such as a broken pilot light or electronic ignition, that prevents the burners from igniting.
Problems with the flame sensor, which detects the presence of a flame and shuts off the system if no flame is detected, even if the system is trying to produce heat.

Have a qualified HVAC technician inspect the burners and ignition system. Cleaning the burners or replacing faulty ignition components may resolve the issue.

Heat Exchanger Problems

In commercial heating systems, the heat exchanger is responsible for transferring heat from the combustion process to the air that circulates through the building. If the heat exchanger is cracked, damaged or malfunctioning, it may not be able to transfer heat effectively, causing the system to blow cool air.

A cracked heat exchanger is a serious issue, as it can also lead to dangerous carbon monoxide leaks in gas-fired systems.

If you suspect a problem with the heat exchanger, shut off the system immediately and contact a commercial HVAC professional. A cracked heat exchanger must be repaired or replaced ASAP as it could pose a threat to those in the building.

Refrigerant Leaks in Heat Pump Systems

Some commercial buildings may use heat pump systems to provide zoned heating and cooling. In heating mode, a heat pump extracts heat from the outside air and transfers it indoors. If the system is low on refrigerant due to a leak, it may not be able to extract enough heat, resulting in cool air being blown through the vents.

Signs of a refrigerant leak include:

The system blowing cool air even when set to heating mode.
Icing on the outdoor unit.
Hissing or bubbling sounds coming from the HVAC system.

Refrigerant leaks must be handled by a licensed HVAC technician. They can repair the leak, recharge the refrigerant and restore the system’s heating capacity.

System Overload or Improper Sizing

In commercial settings, heating systems that are too small for the building’s heating load may struggle to provide adequate warmth. This can lead to the system running continuously without ever reaching the desired temperature, and in some cases, blowing cool air because it is overwhelmed.

If the system is improperly sized, it may be necessary to upgrade to a larger unit that can meet the building’s heating needs. An HVAC professional can perform load calculations to determine the correct system size for your facility.

What Maintenance Can Be Done To Ensure Commercial HVAC Systems Are Running Up to Their Expected Standard?

srobertstoms.rev77@gmail.com (Steve Roberts) — Wed, 25 Sep 2024 22:11:00 GMT

Maintaining commercial HVAC units is essential to ensure they operate efficiently, extend their lifespan and meet the needs of commercial enterprises, public institutions and industrial facilities. Regular maintenance not only helps reduce energy costs but also minimizes the chances of unexpected breakdowns, which can disrupt operations.

Regular Filter Changes

Commercial HVAC systems must have clean filters to function efficiently. Dirty or clogged filters reduce airflow, making the system work harder, which can lead to overheating and increased wear and tear. Changing filters regularly ensures the system’s efficiency and helps maintain good indoor air quality (IAQ).

Filters should be inspected every month and changed every one to three months depending on the usage and air quality requirements for the conditioned structure or area. Clean filters reduce energy consumption and improve the lifespan of the HVAC unit by preventing strain on the system.

The filter needs of a commercial property can vary significantly. A large retail building with rooftop units might have anywhere from 20 to 100 filters depending on the number of units and the building’s layout. Schools with many different classrooms can have dozens or even more than a hundred filters to check and replace. Multi-story office buildings might have 10 to 50 per floor, depending on the system setup and the size of the structure.

Commercial HVAC filter checks and replacements can be time-intensive tasks, but they are important for the health and comfort of occupants as well as the longevity of the system.

Cleaning Condenser and Evaporator Coils

The condenser and evaporator coils in an HVAC unit are essential for heat transfer. Over time, these coils can collect dust, dirt and debris, reducing their ability to absorb and release heat. Dirty coils force the system to work harder, increasing energy consumption and causing performance issues.

In some commercial environments, like industrial and manufacturing facilities, coils may be exposed to more dust, debris and pollutants, necessitating more frequent or aggressive cleaning than might be needed in a standard residential system.

The condenser and evaporator coils should be cleaned at least once a year, especially before the cooling season begins. Cleaning the coils improves heat transfer efficiency, ensuring the system can cool spaces effectively. Professional cleaning may also be a requirement of system warranties.

Checking Refrigerant Levels

For a commercial HVAC system to cool properly, it must maintain the correct amount of refrigerant. Low refrigerant levels can cause issues like reduced cooling capacity, increased energy consumption and even system failure. If refrigerant levels are too low, it may indicate a leak that needs to be addressed.

Refrigerant levels should be checked during routine maintenance visits , and any leaks should be repaired immediately. Because of the size of areas being temperature controlled, even small leaks can result in expensive energy waste. Leaks could also affect the cooling capacity for multiple zones or particularly large spaces, potentially disrupting operations.

Proper refrigerant levels provide optimal cooling performance and prevent damage to the compressor, one of the most expensive parts to replace.

Inspecting and Cleaning Ductwork

Ducts distribute conditioned air throughout the building, so any blockages, leaks or contaminants in the ductwork can negatively impact the HVAC system's efficiency. Ductwork should be inspected annually for leaks, blockages and cleanliness. Cleaning should be done as needed to remove dust, debris and any mold or mildew.

Clean and well-maintained ductwork provides efficient air distribution, reduces energy waste and improves indoor air quality.

Checking and Calibrating Thermostats

Thermostats in commercial buildings can be complex, especially for zoned systems controlling different areas with vastly different temperature control needs, like offices, high-capacity conference rooms and high-traffic areas. Proper calibration is important both to ensure adequate control and to prevent overburdening the system with inconsistent performance.

Some of the more complex commercial thermostats, like those with occupancy sensors, may require particular care and expertise to replace or service. Building managers may also need the assistance of HVAC professionals to properly sync these thermostats with a building automation system to tailor performance based on occupancy levels at different times of day.

Lubricating Moving Parts

The moving parts in a commercial HVAC system , such as fans, motors and bearings, need regular lubrication to minimize friction. Without lubrication, these components can wear out prematurely and cause the system to operate less efficiently. This is particularly vital in a commercial context where HVAC systems operate continuously under a far greater load than a residential system.

Industrial-sized fans and powerful motors require the use of special lubricant types designed to handle high temperatures and enormous stress. These large, complex systems should be serviced by trained, detail-oriented technicians who can perform this time-intensive task with accuracy and thoroughness.

Inspecting Electrical Components and Connections

Electrical issues are a common cause of commercial HVAC system failures due to the higher load. Short circuits and loose, frayed or corroded wires are more likely to lead to major disruptions in a commercial setting. The sophisticated wiring and control systems needed to manage interconnected zones can become extraordinarily complex in large buildings or complexes, and it’s necessary to ensure one connection won’t cause cascading failures that might disable temperature control in large portions of the building.

Relying on handymen, in-house maintenance or inexperienced technicians for HVAC service can result in frequent system repairs and an increased risk of malfunctions that can disrupt critical operations.

One way you can verify that the commercial HVAC company you’re hiring is worth their salt is to check their certifications. When you’re vetting potential HVAC service providers for your commercial property, be sure to ask what certifications they have, what types of coverage and bonding they possess and whether their technicians have any additional manufacturer training or experience with the types of systems you have in your commercial property.

What Certifications Are HVAC Contractors Required to Have?

Every contractor is legally obligated to have a Texas Air Conditioning and Refrigeration Contractor license and an EPA (Environmental Protection Agency) 608 certification in order to perform commercial HVAC services.

The state license verifies they’ve had professional training. The EPA 608 certification, on the other hand, is a federal requirement for those handling refrigerants that ensures they know how to safely handle and properly dispose of them.

Because refrigerant contains hazardous chemicals, improper disposal can result in everything from groundwater contamination to the continued depletion of the ozone layer. Responsible disposal is critical, hence why HVAC technicians must receive certifications to reassure the state they know how to properly dispose of them or recycle them if they’re not contaminated.

While these are the only certifications contractors are legally required to obtain before working, many commercial heating and cooling technicians choose to pursue additional certifications to showcase their exceptional commercial HVAC capabilities to potential clients.

Types of Supplemental Commercial HVAC Certifications

NATE Certification

Possessing the North American Technician Excellence (NATE) certification shows that technicians have passed rigorous exams based on modern HVAC technology.

Only technicians who have worked in the field for at least two years are eligible to sit for the NATE exams. The NATE certification tests their general HVAC knowledge, real-world application of that knowledge and their specialized skills in areas like heat pumps and air balancing. Test takers must have a minimum passing grade of 70 percent to obtain NATE certification.

There are a few variations of the NATE certification:

● Traditional certification, in which the technician takes one core NATE exam and one specialty exam (e.g., heating and cooling, electrical and controls, comfort and airflows, installation and service)

● Professional certification, in which the technician takes five specialty exams

● Senior Efficiency Analyst certification, the highest certification possible, can only be sought after a technician has passed the heating and cooling exam

The certification lasts two years, after which technicians will need to be retested.

HVAC Excellence Certification

The HVAC Excellence Certification , which is available to technicians at levels ranging from entry-level to seasoned technicians, is only available to HVAC professionals who have met certain experience requirements. Two years of real-world HVAC experience is standard, with a three-year minimum for those at the master specialist level. Applicants must take multiple exams to showcase their expertise and skills.

ACCA Quality Installation (QI) Standard

The Air Conditioning Contractors of America (ACCA) Quality Installation certification can only be earned by technicians who are proficient in HVAC system design and installation, duct design, load calculations and other critical aspects of climate control technology. Certified ACCA QI technicians can be depended upon to design and install commercial HVAC systems that will perform optimally for many years to come.

ASHRAE Certification

The American Society of Heating, Refrigerating and Air-Conditioning Engineers certification validates that a technician is equipped to design energy-efficient commercial HVAC systems and has the sophisticated knowledge and skills required to maintain the system’s energy-efficient features.

At Tom’s Commercial, everyone on our team has decades of experience maintaining commercial HVAC units. The technicians we dispatch to your commercial property have been thoroughly vetted to meet our high standards.

Our trust is not freely given – it must be earned by the technicians we hire. Maintaining high standards allows us to confidently tell clients that they will enjoy long-lasting and efficient system performance.

What Other Qualifications Should I Look for in a Commercial HVAC Company?

Aside from standard licenses, bonding, insurance and additional certifications, you should also ensure the HVAC company is specialized in commercial HVAC systems. While there are some similarities in residential and commercial heating and cooling methods, maintaining, designing and repairing commercial systems often involve entirely separate knowledge and skillsets. Some systems, like chillers or industrial-grade boilers , have no real analogs in the residential HVAC space.

At Tom’s Commercial, we have everything you could need in a commercial HVAC company. We’re licensed, bonded, certified, insured and ready 24/7 to provide emergency services to prevent your business from grinding to a halt due to climate control disruptions.

What Are the Factors to Consider When Choosing a Commercial AC Repair Service in Arlington, TX?

Thu, 11 Apr 2024 17:35:14 GMT

Properly functioning HVAC is integral to creating a comfortable environment for customers and working conditions for staff. Even a minor technical issue with your AC can disrupt operations and impede profits.

Suffice it to say that finding a reputable and reliable commercial HVAC repair service is paramount to protecting your bottom line – but not all service providers are equal. Too many commercial AC repair companies talk up their capabilities, experience working on commercial systems or the quality of their service without delivering on the expectations they set.

It’s important to do your due diligence to ensure whoever you hire has the experience, expertise and top-of-the-line equipment to adequately assist you and keep your HVAC unit running smoothly for longer – which you’re guaranteed to get when you hire Tom’s Commercial for your building’s HVAC needs.

What to Look for in a Commercial AC Repair Service

Licensed, Certified and Insured

Many business owners would be surprised how many companies and contractors that work on HVAC units don’t have the proper licenses, insurance or certifications to do so. Confirming that your service provider is licensed and certified guarantees they’ve been trained to maintain complex commercial HVAC units effectively and safely with minimal risk of damage.

You should also verify that they carry liability insurance, so you’re protected in case of accidental property damage or injuries during repairs. At Tom’s Commercial, everyone on our team is an expert in commercial HVAC systems, meaning business owners are guaranteed their building will only be worked on by licensed, certified and insured HVAC technicians.

Commercial Specialization

Residential and commercial HVAC maintenance require two entirely different realms of expertise. Commercial HVAC units are bigger, contain significantly more complicated mechanisms and often have components in hard-to-reach places. Moreover, because of the unique use cases and varied system designs inherent in the realm of commercial HVAC, maintaining one commercial unit could require a completely different strategy from another.

Some companies may say they service, repair and replace all types of commercial HVAC setups, but only have a history of maintaining small-scale or straightforward commercial systems. Ensure the Arlington company you hire has extensive experience working on a diverse variety of commercial HVAC units and has the know-how and equipment to perform adequate repairs and replacements.

24/7 Emergency Service

HVAC repairs are rarely planned. This is especially the case in Arlington, where summer can put a serious strain on commercial systems.

How to Tell If You Are Getting Shoddy Commercial HVAC Services

Thu, 11 Apr 2024 17:25:16 GMT

Unfortunately, second-rate commercial HVAC service companies are pervasive in the industry. Nearly 20 percent of HVAC repair companies across the country fail every year, with 70 percent shuttering within their first year of operations. Operational history matters, and a business that’s been operating for decades is likely offering a level of quality workmanship and customer service their short-lived competitors fail to deliver.

Company longevity matters for a few reasons:

It’s easier to trust the quality of work delivered by experts who have been in the business for a long time.
If something goes wrong with your repair, maintenance or new system installation, you want to know the company that gave you a guarantee six months ago will be around to fulfill the promises they made.
It can give you peace of mind knowing your service provider is a long-standing member of the community that cares about local businesses and has a reputation to protect.

Good commercial HVAC service companies that stand the test of time with ample certifications and stellar professionalism are hard to come by, which is why many Arlington business owners depend on Tom’s Commercial for their commercial HVAC servicing needs.

When you hire Tom’s Commercial, a company that has been installing and maintaining commercial HVAC systems in the Arlington area for more than 60 years, you’re hiring trained and experienced technicians with a long-standing reputation in the community for providing exceptional service. We got here by always putting the customers’ needs and preferences first.

Signs You Need to Switch HVAC Service Providers

Short-Lived Results

If issues reappear shortly after a maintenance visit or continue to worsen and grow more expensive over time, it may be a sign that your HVAC unit isn’t being properly maintained. Common issues include an increased presence of dust or a general decline in indoor air quality, inconsistent temperature output and skyrocketing utility bill costs. While this can also indicate that the unit is old and needs to be replaced, a qualified HVAC technician likely should have been able to inform you of imminent system problems during a routine inspection before the system had the chance to break down.

Ill-Prepared Visits

Inexperienced HVAC technicians tend to prolong visits by forgetting essential equipment, constantly leaving to pick up parts and delaying the actual service or repair. Qualified technicians have the expertise to know what tools and equipment they need to get the job done right on the first visit or with a single trip to the parts warehouse.

Always Replacements, Never Repairs

Despite a company saying they specialize in both HVAC repairs and replacements, many shoddy HVAC service providers will push business owners to replace parts or entire units just to pad their bottom lines.

Older units will need to be replaced sooner or later, but if your technician is telling you to replace a system without giving you a clear explanation for why that is preferable to a more affordable repair, it’s not the unit that needs replacing.

A good HVAC service provider doesn’t need to lie to stay in business. At Tom’s Commercial, we pride ourselves on our integrity and being upfront with our customers. If a commercial air conditioner can be repaired, we’ll work diligently to restore it. If replacement is unavoidable, we’ll install a new system quickly to minimize interruptions to your business.

Amateur Service

Professionalism isn’t a bonus – it’s a necessity. As a business owner, your time and investment warrant respect that a good HVAC service provider will honor. Amateur HVAC technicians are quick to forget this and may be inattentive to customer needs, provide poor communication and only offer a rigid set of one-size-fits-all solutions to address unique issues.

Poor Communication

A lack of transparency or clear expectations is a big hint that someone is an amateur. Watch out for commercial HVAC service companies that neglect to establish a definitive service timeline for maintenance or refuse to give you a clear estimate until the service is finished.

If you’re never sure what to expect next, something’s wrong. Moreover, if they don’t clearly disclose their certifications, licenses or business information, they’re likely not producing results they’re proud of. At Tom’s Commercial, we pride ourselves on 100 percent customer satisfaction and will go above and beyond to meet your business’s HVAC needs.

What Are Some of the Most Common Problems that Cause Poor Ventilation?

Mon, 29 May 2023 21:46:41 GMT

Adequate ventilation plays a significant role in maintaining good indoor air quality by exchanging stale air with fresh outdoor air. On the other hand, poor ventilation can lead to a range of issues, including stuffy rooms, persistent odors, increased humidity and even potential health concerns.

If you’re an Arlington business owner, it’s important that you maintain adequate ventilation in your commercial space by regularly inspecting your vents and scheduling annual maintenance for your HVAC system.

Common Problems that Cause Poor Ventilation in Commercial Spaces in Arlington, TX

Blocked or Obstructed Vents

Blocked or obstructed vents are a common culprit behind poor ventilation. Accumulated dust, debris or furniture blocking the vents can restrict the flow of air, resulting in inadequate ventilation.

Remedy: Regularly inspect and clean all vents to ensure they are free from obstructions. Move furniture and objects away from vents to allow unobstructed airflow. Consider using vent covers to prevent dust and debris buildup.

Inadequate Ventilation Design

Sometimes, poor ventilation can be attributed to a flawed or inadequate ventilation system design. Insufficient airflow due to improper duct sizing, lack of ventilation outlets or inadequate supply and return airflow balance can hinder the effectiveness of the system.

Remedy: Addressing inadequate ventilation design is crucial to mitigate these air circulation challenges and improve indoor air quality. The HVAC specialists and ventilation engineers at Tom’s Commercial can help identify and rectify design flaws. Potential solutions may include adjusting ductwork, upgrading ventilation systems or implementing proper airflow balancing techniques.

Improperly Sealed Windows and Doors

Leaky windows and doors can contribute to poor ventilation. These gaps allow outdoor air to infiltrate, disrupting intended airflow patterns and leading to compromised ventilation.

Remedy: Inspect windows and doors for any gaps or cracks. Weatherstripping and caulking can help seal these openings, preventing unwanted air infiltration. Expanding foam sealant can also be used to fill larger gaps or spaces around windows and doors. These products expand when applied to provide a tight seal, reducing air leakage and enhancing insulation properties.

In cases of severe leaks or aging windows, consider investing in energy-efficient windows that offer better insulation and airtightness.

Clogged or Dirty Air Filters

Dirty or clogged air filters can impede the airflow in HVAC systems, reducing ventilation efficiency. Restricted airflow leads to poor air circulation and compromises indoor air quality.

Remedy: Check and replace air filters every three months or as recommended by your HVAC professional. Clean filters ensure optimal airflow, prevent the accumulation of dust and debris and promote better ventilation.

Inadequate Exhaust Ventilation

Insufficient exhaust ventilation in specific areas, such as kitchens and bathrooms, can result in poor overall air distribution. Without proper exhaust mechanisms, moisture, cooking fumes and odors may linger, leading to a less-than-pleasant indoor atmosphere and even potential health hazards.

Remedy: Install or upgrade exhaust fans in areas prone to high humidity or strong odors. Ensure the exhaust fans are appropriately sized and vented to the outdoors to effectively remove pollutants and maintain proper ventilation. In areas where there may be inadequate ventilation like kitchens, bathrooms and laundry rooms, consider installing additional exhaust fans. Place the fans strategically to ensure optimal air circulation and removal of contaminants.

Improperly Balanced HVAC System

An HVAC system that is improperly balanced can unevenly distribute air, causing some areas to receive inadequate ventilation while others experience excessive airflow.

Remedy: You’ll need to engage an HVAC professional to assess and balance your HVAC system. By adjusting dampers, air registers and fan speeds, you can ensure balanced airflow throughout your space, promoting optimal ventilation and comfort.

What Are Some Structural Damages to Look for When It Comes to Commercial HVAC Maintenance?

Mon, 15 May 2023 21:38:26 GMT

What Are Some Structural Damages to Look for When It Comes to Commercial HVAC Maintenance in Arlington, TX?

Your Arlington business’s commercial HVAC system is likely far larger and more powerful than the residential system on your home due to the larger cubic footage it’s designed to serve. Because of its complexity and heavier operational load, it’s safe to assume the system also requires more frequent and specialized maintenance than the average residential heating and cooling solution.

In fact, when it comes to commercial HVAC systems, regular maintenance is crucial for optimal performance and longevity. While many technicians focus on mechanical components during maintenance, it's equally important to pay attention to structural damages that can impact the system’s efficiency and functionality. By scheduling regular commercial HVAC maintenance, you can help keep your commercial HVAC system in excellent working condition and address any structural damage that may compromise its efficiency and functionality.

Ductwork Damage

One of the primary structural elements of a commercial HVAC system is the ductwork. Damaged ducts can lead to air leaks, inefficient airflow and poor indoor air quality. During maintenance, technicians should inspect the ductwork for signs of leaks, loose connections, crushed or collapsed sections and damaged insulation. Repairing or replacing damaged ductwork ensures proper airflow distribution, improves energy efficiency and helps maintain optimal indoor air quality.

Roof Penetrations and Flashing

Roof penetrations, such as those for HVAC units, exhaust systems or vents, are vulnerable areas that can cause structural issues if not properly sealed and maintained. Improperly sealed or damaged flashing around roof penetrations can result in water leakage. Water intrusion can lead to significant damage to the HVAC unit and its components, such as electrical systems, motors, controls and insulation. Moisture can cause corrosion, rust and short circuits, compromising the unit's performance and potentially leading to costly repairs or even system failure.

What’s more, water leakage due to inadequate flashing can lead to moisture buildup within the building's structure. Excessive moisture can create an ideal environment for mold and mildew growth. Mold growth not only affects indoor air quality but can also spread to the HVAC unit, contaminating its components and ductwork. This can result in health concerns for your customers, employees and other building occupants and further damage the HVAC system.

Insufficient Insulation

Insulation is critical for maintaining energy efficiency and minimizing temperature fluctuations. Inadequate or damaged insulation can result in heat gain or loss, leading to increased energy consumption and reduced HVAC system performance. During maintenance, technicians should check for damaged or missing insulation in areas such as air handlers, ductwork and piping.

Repairing or replacing insulation ensures optimal thermal efficiency, reduces energy waste and improves overall system performance.

Damaged or Obstructed Vents

Proper airflow is essential for effective HVAC operation. Damaged or obstructed supply and return vents can disrupt airflow, causing imbalances in temperature distribution and reduce system efficiency. During maintenance, technicians should inspect all vents to ensure they are not damaged or blocked by debris, furniture or other objects. Cleaning and clearing vents allow for unrestricted airflow, promoting balanced temperature distribution and maximizing system performance.

Water Leakage and Condensate Drainage Issues

Water leakage and condensate drainage problems can occur in commercial HVAC systems, particularly in humid climates like in Arlington or areas with high condensation levels. Poorly maintained condensate drain lines, clogged drain pans or damaged seals can lead to water accumulation, which can cause structural damage, mold growth and compromised indoor air quality. Your commercial HVAC maintenance service should include checking condensate drain lines, pans and seals to ensure proper drainage and prevent water damage.

Building Envelope Integrity

The building envelope, including walls, windows and doors, plays a significant role in maintaining energy efficiency and preventing outdoor elements from impacting indoor comfort. Cracks, gaps or damaged seals in the building envelope can result in air leaks, moisture intrusion and increased energy consumption. During maintenance, technicians should inspect the building envelope for any signs of damage or deterioration and recommend repairs or improvements to maintain a tightly sealed and efficient building envelope.

How Long Do Commercial Heaters Usually Last?

Tue, 18 Apr 2023 17:21:59 GMT

How Long Do Commercial Heaters Usually Last?

How long a commercial HVAC system lasts depends on the type of heating or cooling system, how frequently it’s used and the temperature-control demands to which it is subjected on an annual basis. Factors like maintenance frequency (and quality) will also directly impact a commercial heating system’s longevity.

On average, commercial heating systems can last anywhere from 15 to 30 years, with some well-maintained systems lasting longer.

Average Lifespans for Commercial Heating System

Different types of heating systems, such as boilers, furnaces and heat pumps, may have different expected lifespans. For example, boilers tend to last longer (20 to 30 years) than furnaces (15 to 20 years) due to fewer moving parts.

Commercial Furnaces: Gas and oil-fired furnaces typically have a lifespan of around 15 to 20 years under normal operational demands and when properly maintained. Regular inspection and cleaning, along with timely replacement of filters and worn components, can help extend the life of a furnace.

Commercial Boilers: Boilers usually last longer than furnaces in part because they have fewer moving parts. A well-maintained commercial boiler can last between 20 to 30 years, sometimes even longer. The life expectancy of a boiler can depend on factors such as the type of boiler (e.g., condensing or non-condensing), the materials used and the quality of the components.

Heat Pumps: Commercial heat pumps, which provide both heating and cooling, typically have a lifespan of around 15 to 20 years (roughly the same as the average residential heat pump). Proper maintenance, such as cleaning coils, replacing filters and ensuring adequate refrigerant levels, can help extend the life of a heat pump.

Radiant Heating Systems: Radiant heating systems, which use heated water or electric elements to heat floors, walls or ceilings, can have varying lifespans depending on the type of system. Electric radiant heating systems generally last 20 to 30 years while hydronic (water-based) systems can last even longer, up to 40 years or more, with proper maintenance.

Unit Heaters: Unit heaters, which are often used in warehouses and other large spaces, can last for 15 to 20 years with proper maintenance. The lifespan of a unit heater can be affected by factors such as the quality of components, environmental conditions and usage patterns.

Quality of the System and Components

High-quality components and materials used in the manufacturing of the heating system can contribute to a longer lifespan. The needs of the average commercial structure can be extremely varied. Choosing the right system from the varied options available is vital to maintaining necessary environmental control in your structure. The good news is there is a high-quality, efficient and long-lasting system for you, whether it’s a packaged product or split system.

Because commercial systems are often more complex, there are situations in which some parts of a system may last longer than others. For example, the outdoor condensing unit of a split-system may only offer optimal efficiency for 10 to 15 years while the indoor air handling portion of the system can operate effectively for 20 years. An experienced commercial HVAC professional from Tom’s Commercial can advise you on how long your system should last and what you can do to maximize its projected lifespan.

HVAC Maintenance

Regular maintenance , including cleaning, filter replacements and periodic inspections, can extend the life of commercial heaters. A well-maintained heating system is more likely to last longer and perform more efficiently.

Usage

How often a commercial heating system is used and the conditions under which it operates can affect its lifespan. Systems that are constantly running or those that are subjected to harsh environments may have a shorter life expectancy.

Installation

Proper installation of the heating system by qualified professionals can have a significant impact on its longevity. Incorrect installation can lead to premature failure or reduced efficiency. As a property owner, your choice of system is particularly important, but your choice of installer can be equally vital.

Reputation, training and commitment to customer satisfaction are important attributes to look for when you’re choosing a commercial heating and cooling company . The team at Tom’s Commercial understands the needs of local Arlington-area businesses and strives to exceed those needs every day.

How to Get the Most Out of Your Commercial HVAC System

To ensure the longest possible life for your commercial heating system, invest in quality equipment , follow the manufacturer's guidelines for maintenance and have regular inspections and servicing performed by qualified professionals.

The team at Tom’s Commercial is committed to meeting all the needs of local Arlington-area businesses, schools, office complexes, light-industrial clients and more. Whatever your commercial HVAC needs are, our certified and dedicated technicians can help.

What Are the Different Types of Commercial HVAC Units and How Are They Different?

Mon, 10 Apr 2023 17:13:13 GMT

What Are the Different Types of Commercial HVAC Units and How Are They Different?

The cubic footage of commercial and multi-family properties often dwarfs residential properties. Heating and cooling large, multifaceted spaces that often feature high ceilings, complex layouts and potentially simultaneous heating and cooling demands isn’t always straightforward.

Multi-family properties like apartment buildings need vast networks for ventilation and capacity to push temperature-controlled air long distances. Retail stores often possess massive open areas with incredibly high ceilings.

The average big-box hardware store, like Lowe’s or Home Depot, might have ceilings that are 20 or 30 feet high for added storage. Other types of structures, like distribution centers and warehouses, may have similarly large open areas and a need to maintain precise temperature control throughout.

Designing and implementing heating and cooling solutions to meet the needs of these facilities is no easy feat. Keeping those systems properly maintained and operating at peak efficiency can also be more labor intensive than the average residential HVAC system. At Tom’s Commercial, we’re committed to being the one-stop HVAC solution provider for businesses and property owners throughout the Arlington, TX area.

Common Types and Configurations of Commercial HVAC Systems

Single Split Systems

Single split systems are popular, cost-effective heating and cooling solutions for smaller commercial buildings. These systems consist of an air conditioner to cool the refrigerant, a furnace with an evaporator coil to convert the refrigerant and a duct system to distribute the temperature-controlled air. Each indoor unit is connected to an individual outdoor unit, providing independent temperature control for each zone.

Multi-Split Systems

Multi-split systems are suitable for medium-sized commercial and multi-family residential buildings as they allow for multiple indoor units to be connected to a single outdoor unit. This configuration is energy-efficient, space-saving and provides individual temperature control for each zone. These systems can accommodate various indoor unit types, including wall-mounted, ceiling-mounted and concealed ducted units.

What Are VRF (Variable Refrigerant Flow) and VRV (Variable Refrigerant Volume) Systems and How Are They Different?

Variable refrigerant flow and variable refrigerant volume systems are ideal for large commercial buildings as they can provide simultaneous heating and cooling to different zones. These systems use variable-speed compressors to modulate the refrigerant flow according to the building's requirements, enhancing energy efficiency.

The Two Main Types of VRF Systems

Heat Pump VRF Systems

Heat pump VRF systems can provide either heating or cooling to the entire building at a given time but cannot provide both simultaneously.

Heat Recovery VRF Systems

These systems can simultaneously provide heating and cooling to different zones, making them ideal for large commercial spaces with varying temperature requirements.

Which HVAC Solution Is Best for Businesses, Schools and Large Facilities in the Arlington, TX Area?

A variety of factors like price, capacity, efficiency, space constraints, building layout and occupancy may play a role in a property owner’s heating and cooling choices. Even the lowest cost option will inevitably represent a large investment in property infrastructure, which is why these are among the most important and impactful choices an owner may need to make.

The team at Tom’s Commercial is here to answer any questions you may have about which systems work best for your property’s heating and cooling needs. Call us at (817) 984-5779 for a consultation.

What Does Pooling Indicate with a Commercial AC Unit?

Mon, 20 Mar 2023 18:23:58 GMT

What Does Pooling Indicate with a Commercial AC Unit?

Water pooling around your commercial AC unit is never a good thing. In fact, an AC leaking water can indicate a serious problem with your commercial air conditioner, such as condensation buildup, a broken condensate pump or damaged drain pan (all of which require professional repair).

If you notice a perpetual puddle near your AC unit, be sure to turn it off and call an HVAC professional for help. Continuing to use the unit may lead to roof damage, cooling performance issues and even a complete system breakdown.

Although water leaking from your unit requires professional intervention, there is no need to worry. A skilled HVAC technician from Tom’s Commercial can inspect your AC unit, determine the cause of the leak and fix the issue in a timely and hassle-free manner, preventing unwanted business interruptions.

Why Is My AC Leaking Water?

Clogged Condensate Drain Line

The condensation drain line carries away the water that is created when the AC pulls moisture from the air to reduce indoor humidity. If the line becomes clogged, it can cause water to back up and overflow, leading to water pooling around the unit. The most common cause of a clogged condensation drain line is dirt and debris that has built up over time.

You can clean the drain line by scrubbing it with a brush and flushing it out with clean water. However, if the line is severely clogged or the blockage is difficult to reach, it may be best to leave the job to a professional.

Damaged Drain Pan

A drain pan is a shallow pan that is installed beneath the evaporator coil to collect condensation that forms during the cooling process. The condensation is then drained away from the unit, usually through a drain line.

If the drain pan is damaged, it can cause water to leak and damage the surrounding area instead of flowing into the line. Additionally, a damaged drain pan can lead to mold and mildew growth, which can be hazardous to the health of employees and customers.

You can try to patch the cracks in the damaged drain pan with a sealant. However, it's usually best to call an HVAC professional who can replace it with a new one.

Broken Condensate Pump

A condensate pump removes condensation from an air conditioning system. It's typically installed in the drain line of the AC and pumps the condensate water out of the building.

When the pump is broken, water will accumulate and eventually cause water damage to your business's walls, floors and furniture.

If you suspect your condensate pump isn't working properly, contact a professional HVAC technician right away. There are no DIY solutions to this issue, but a technician will be able to repair or replace the pump depending on the degree of damage.

Drain Line Isn’t Attached Properly

When your AC unit's drain line is not properly attached, it can cause a variety of problems. The most common issue is water leaking from the unit, which can damage the surrounding area and create a health hazard. Additionally, the air conditioner may not be able to cool your commercial space efficiently due to the lack of proper drainage.

To fix the issue, contact an HVAC professional who can reconnect the drain line and inspect it for any signs of wear or damage.

Frozen Evaporator Coils

The evaporator coils in an AC unit are responsible for cooling the air that is circulated throughout the building. The most common cause of frozen evaporator coils is low refrigerant levels. When the refrigerant level is too low, it causes the temperature of the coil to drop below freezing, resulting in ice forming on the coil.

Moisture can build up when the evaporator coils freeze, which then causes the drain pan to overflow and the AC to leak water.

If you suspect that your evaporator coils are frozen, contact a professional HVAC technician right away for assistance. They will be able to diagnose the issue and recommend a course of action for the repair or replacement of your AC system components.

Contact Tom's Commercial for Business AC Repair, Replacement and Maintenance in Arlington

If you own a business in Texas, you’re under no legal obligation to close it if you’re getting AC repairs. According to the Occupational Safety and Health Administration , there are no set rules on temperature regulation in a workplace. In other words, you can technically run your Arlington business without a working AC on a hot summer day without worrying about legal repercussions.

However, keeping your business open while your AC is broken can leave a negative impression on both your employees and customers. It may also result in potential workers’ comp claims if employees suffer heat stroke and require medical care.

No one wants to endure the heat and humidity of a broken air conditioner while out and about, whether they are trying to enjoying a meal at a restaurant, shopping for clothes or working out at a fitness club. Additionally, the lack of cool air can cause a decrease in productivity for your employees.

The result of a broken commercial AC? Potentially a decrease in customer satisfaction, negative publicity (those one-star online reviews) and a decrease in profits.

Luckily, even extensive commercial AC repairs can be handled promptly if you have a knowledgeable and experienced HVAC professional in your contacts. A quick and accurate diagnosis paired with a detailed plan of action for the AC repair can restore your business’s temperature control in no time.

Signs Your Commercial AC Unit Needs Repairs

Unusual Noises

Typically, an AC will make a low, consistent sound as it continues to blow cool air into your commercial space. People working in the same building for years will become so familiar with the noise of the HVAC system that it will entirely fade into the background – until something changes.

If you notice the unit is making unusual and loud noises, such as grinding, rattling or squealing, or the sound suddenly disappears altogether, it could be a sign that something within the unit is damaged or broken.

Poor Airflow

If the air coming out of your vents is weak or not blowing at all, it could be a sign that something is wrong with your AC unit and needs to be repaired. Common causes of poor airflow in commercial AC systems include:

· Clogged air filters

· Blocked ducts

· Faulty components, such as fans, motors and compressors

High Energy Bills

If you’ve noticed an increase in your energy bills without any changes in usage, it could be a sign that your AC unit isn’t running efficiently. It could also be a sign the building isn’t properly insulated or that there is an issue with your ductwork. An HVAC technician can inspect your system and determine the cause of the issue.

Leaks

A leaking AC or water pooling around the unit can be attributable to several potential issues, including a clogged condensate drain, damaged evaporator coil or refrigerant leak. If you notice a puddle of water around your commercial air conditioner, turn it off and contact an HVAC technician as soon as possible. The team at Tom’s Commercial can diagnose and repair the issue quickly.

Unpleasant Odors

The most common cause of unpleasant odors coming from a commercial AC unit is the buildup of dirt, dust and other debris in the air filter or ductwork. This can lead to mold and mildew growth, which can produce an unpleasant musty smell. Other causes include clogged drain lines, which can lead to standing water and a sewage-like odor, or a refrigerant leak, which can produce a chemical smell.

If you notice an unpleasant or strange odor coming from your commercial AC unit, don’t hesitate to have it inspected by a professional.

When to Choose a Commercial AC Replacement Instead of Repairs

Even the most innovative, expensive and energy-efficient commercial AC unit won’t last forever. Although most commercial ACs can last decades, there will come a time when repairs are not enough to maintain constant, reliable and efficient cooling. In this case, a commercial AC replacement may be a better option.

Below are some things to consider when deciding whether to pay for another repair or invest in replacement:

Age: If your commercial AC system is more than 15 years old, it may be time for a replacement. As air conditioners age, they become less efficient and require more frequent repairs. Replacing an older system with a newer model can help you save money on energy costs in the long run.

Poor performance: If your commercial AC system isn’t cooling your space as well as it used to, it may be time for a replacement. A new system will be more efficient and better able to keep up with your commercial cooling needs.

Frequent breakdowns: If your commercial AC system is constantly breaking down and requiring frequent and costly repairs, replacing it may be the best option to avoid frequent downtime and disruptions to your business operations.

How Can I Figure Out How Many HVAC Units I Need for My Business?

Mon, 23 Jan 2023 18:10:06 GMT

How Can I Figure Out How Many HVAC Units I Need for My Business?

The number of HVAC units needed for your business will largely depend on the cubic footage of your space. However, volume is not the sole factor for determining how many HVAC units will be effective for heating and cooling your commercial space. Others include:

The layout of your building
How many windows it has
How much traffic you receive
Difference between indoor and outdoor temperature
Insulation

It's important to have the correct HVAC capacity to adequately heat or cool your business on the hottest and coldest days in Arlington. There are often multiple ways to reach that threshold of temperature control. The number and size of your HVAC units will have a direct impact on how well they can heat or cool your space.

Having a single unit that is too small or having too few units will force them to work extra to maintain the temperature of your business, potentially leading to high energy costs and premature failure. An HVAC unit that is too large may waste energy, short cycle and fail to provide consistent temperature control.

To determine what size HVAC unit your building requires or the number of systems you need, you can use an HVAC load calculation. An HVAC load calculation will tell you how many BTUs (British thermal units) are needed to effectively air condition your space based on the amount of cubic footage available.

More precise calculations are possible with the help of professional HVAC installers like the ones here at Tom's Mechanical. When determining how many units you'll need for your business, we carefully evaluate the specifications of your building and any factors that may affect the efficiency of HVAC units in your space.

What Factors Influence HVAC Capacity Requirements?

A trained HVAC installer will be able to determine the baseline of your HVAC needs based on the cubic footage of your space (length x width x space).

Several factors ultimately affect how much HVAC power you will need. These can include:

Ceiling height: Higher ceilings require more airflow to keep the business cool.
Commercial building use: If there are higher volumes of people in the building during the day, your HVAC system will need to contend with significant body heat plus doors opening regularly and letting heated or cooled air out. In many commercial properties, the AC unit is running even when the building is not occupied. You’ll need to consider how much your HVAC units need to run when the building is both in use and not in use to determine how much power and how many units are required.
Building insulation: A well-insulated building may be less susceptible to the temperatures outside, whereas a building that is poorly insulated may require more powerful HVAC units to maintain appropriate temperatures.

Leave it to a trusted Arlington HVAC installer to help you determine your exact commercial building HVAC needs. An expert in commercial temperature control can help you understand the building factors that may indicate whether you need more units or units that are better sized to keep up with your required temperature output.

What Is the HVAC Load Calculation?

An HVAC load calculation will show you the number of BTUs that are necessary for effective heating and cooling of your business. The formula outlines the base level of the HVAC capacity your building will require.

Factors that an HVAC system design and installation specialist will take into account when performing a load calculation include average occupancy (both customers and employees), number of doors and windows, peak traffic and cubic footage (square feet x ceiling height).

Should I Get an Air Quality Test Done at my Business?

Mon, 09 Jan 2023 18:02:18 GMT

Should I Get an Air Quality Test Done at my Business?

If you want to take preventative measures against potential indoor air quality threats, then it's a good idea to have an indoor air quality test performed. Indoor air quality tests can identify potential biological, chemical or combustible gas pollutants in the air.

There are many reasons that your indoor air quality may be declining, but it can be difficult to get to the root of these issues without a professional HVAC servicer to inspect your business thoroughly.

In addition to an indoor air quality test, you may benefit from an HVAC inspection and an assessment of your current IAQ equipment, as some pollutants may be attributable to a malfunctioning or inefficient HVAC unit that is not filtering out contaminants properly.

The quality of the air in your business has an impact on your employees, customers and your reputation. An indoor air quality test can give you peace of mind about the safety of your environment, so it is worth the investment for your business.

Reasons to Schedule an Indoor Air Quality (IAQ) Test

Indoor air quality testing can help you measure any risks that might be in your air that could pose a hazard to patrons and workers. You can’t see harmful levels of pollutants, and in many cases, you can’t smell them either. Just because gasses or allergens are odorless does not mean their impact is insignificant.

Indoor air quality tests can help identify potential:

VOCs (volatile organic compounds)
Mold spores
Toxic gasses like formaldehyde or carbon monoxide
Allergens
Dust, dander and small debris

The risk of biological, chemical and combustible gas pollutants may jeopardize your business if they begin to harm customers. In addition to opening your business up to liability, illnesses linked to your building can damage your reputation among local consumers and job seekers.

By investing in indoor air quality testing for your business, you can prevent pollutants in the air from causing more serious issues down the line. You can’t solve a problem that you’re not aware of, which is why early testing can be crucial.

Benefits of Indoor Air Quality Testing

Take Preventative Measures Against Potential Contaminant Threats

Pollutants can build up and have a cumulative negative impact on your business if they remain unnoticed. They're not visible to the naked eye, are often odorless and they may not cause any symptoms until there's a major issue. Pollutant pathways and contaminant sources may be difficult to identify without proper air sampling, but once that's done, you will be on track to making your workplace a much safer environment.

Improve Workplace Conditions for Your Employees and Customers

Safer air quality means it's a healthier environment for those who visit your business. Your sales and reputation will suffer if people don't feel safe entering your building. Improving the workplace by ensuring pure air quality can ensure pollutants don’t hinder your business success.

Healthy employees who don’t need sick days due to allergies or illnesses are also better for your bottom line. A worker who is constantly suffering from watery eyes and a runny nose because of allergens in the workplace will be less productive.

Maintain Indoor Air Quality with Regular HVAC Servicing

Sometimes, pollutants can be traced back to a malfunctioning or under-serviced HVAC system. If this is the case, having indoor air quality testing performed at your business can help to expose HVAC issues that need to be addressed. Regular service can help to make sure your air filtration system is working properly, which keeps pollutants from building up within the environment.

Signs of Poor Air Quality at Work in Arlington, Texas

An indication that you may need to look into the air quality of your business is the state of the people spending time within your building. You may notice more complaints of allergies or breathing issues than usual, or employees and customers may begin exhibiting similar health issues that appear to have no other cause or commonality other than being in your building.

Signs that may indicate poor air quality include:

Complaints of headaches
Worsening allergy symptoms
Burning sensation in nasal passages
Odd smells

The causes of compromised air quality can vary from ventilation issues to contaminants like asbestos within the walls. Air is constantly being filtered via your HVAC system. The presence and buildup of contaminants may indicate there is some issue in that process.

What Are the Different Types of Commercial Air Ducts?

Mon, 12 Dec 2022 20:57:31 GMT

Commercial air ducts are a crucial part of any building's ventilation system. They are connected to the HVAC system and carry the heated or cooled air from the furnace, heat pump or air conditioner to each room in the building. The return ducts also send air back to the HVAC system for reheating or recooling and filtering purposes.

There are a number of different types of commercial air ducts available for purchase. If you’re looking to install a new HVAC system in your commercial building, take some time to familiarize yourself with the different types of commercial air ducts. This will help you choose the best and most efficient option for your unit and space.

The Types of Commercial Air Ducts

Sheet Metal Air Ducts

As the name implies, these ducts are usually made from galvanized steel or aluminum. They can be either round or rectangular in shape and come in various sizes depending on the application. Sheet metal air ducts are usually connected with screws, rivets or other fasteners. The joints between the pieces of sheet metal must be sealed with mastic sealant to prevent air leakage.

Sheet metal air ducts have several advantages over other types of air duct systems. They are relatively easy to install and maintain, provide good airflow and can be customized for specific applications. However, the main benefit of sheet metal air ducts is that they’re durable and resistant to corrosion. These properties make them ideal for use in commercial buildings and areas with high humidity levels or where there is a risk of water damage.

Fiberglass Lined Air Ducts

Fiberglass lined air ducts are a type of air duct system that is designed to provide superior insulation and soundproofing. The fiberglass lining helps to reduce the amount of noise that is transmitted through the ducts while also providing an additional layer of insulation.

Their soundproof properties make them a popular choice for commercial and industrial buildings, where noise levels need to be kept to a minimum.

Other advantages of fiberglass lined air ducts include:

Easy installation and maintenance
Relatively inexpensive compared to other types of air duct systems
The exterior can be customized with different colors and textures in order to match any existing décor or design scheme

Fiberboard Air Ducts

Fiberboard air ducts are typically made from either cellulose or fiberglass insulation. The insulation helps to reduce noise levels and improve energy efficiency by preventing heat loss or gain through the walls of the ducts. The insulation also helps to protect the interior of the building from dust, dirt and other airborne particles. These ducts may not be as durable as other types of air ducts, but they are budget friendly and come in a variety of sizes and shapes, making them suitable for many different applications.

Flexible Non-Metallic Air Ducts

Flexible non-metallic air ducts are made from a variety of materials, including PVC and polyethylene. They are designed to be flexible and can be bent or shaped to fit into tight spaces or around obstacles. This makes them ideal for use in tight spaces such as attics or crawlspaces.

Thanks to their flexibility, these air ducts are generally much easier to install than traditional metal ducts. They can be cut with scissors or a utility knife and require no special tools or equipment to install.

Flexible non-metallic air ducts are also known for their superior air flow properties due to their smooth interior walls and lack of sharp edges that can cause turbulence in the airflow. This improved airflow helps reduce energy costs by allowing the HVAC system to run more efficiently.

Which Type of Commercial Air Duct Is Right for Your Space?

The type of air duct that is right for your commercial space depends on several factors, including the size and layout of the space, the type of HVAC system you currently have installed or are having installed and the amount of air flow needed.

Round metal ducts tend to be ideal for many commercial applications, as they are durable and can handle high air flow rates. However, if you have a smaller space or need to reduce noise levels, flexible ducts may be a better option. If you’re concerned about efficiency, insulated ducts can help reduce energy costs by keeping conditioned air from escaping through the walls of the ductwork.

Ultimately, your best bet is to consult with a skilled commercial HVAC professional to determine which type of air duct is best for your unique needs.

Why Is There a Burning Smell Coming from My Heater?

Mon, 07 Nov 2022 20:47:23 GMT

Why Is There a Burning Smell Coming from My Heater?

A burning smell coming from your heater could be caused by several things. It could be due to dust and debris that has built up in the heater, which then burns when the heater is turned on. It could also be caused by a faulty electrical component, such as a bad motor or capacitor, or it could be due to an oil leak.

If you notice the smell persists despite doing things like replacing air filters and cleaning air vents, it may be best and safest to have an HVAC professional inspect your heater to determine the cause and proceed with repairs.

Reasons Why a Heater Smells Like It’s Burning

Dust Has Accumulated in the Heater

Dust is one of the main causes of a burning smell when you turn on your heater. Have you noticed this burning smell the first time you turn on your furnace in the heating season? Your heater is likely burning off dust it’s accumulated during months of inactivity.

Although the smell coming from your heater may be unpleasant, it usually lasts only a couple of hours. If you’re particularly bothered by the smell, it helps to open a window or turn on a ventilation fan until the smell goes away.

Old Filters

Replacing air filters is an important part of keeping unpleasant smells at bay and keeping a healthy space for customers and employees.

Air filters help to remove dust, dirt and other airborne particles from the air, which can help to reduce allergies and improve air quality. Replacing your air filter regularly can also help to improve the efficiency of your HVAC system, as a clogged filter can cause it to work harder than necessary.

Dirty Air Vents

A burning smell in your heater may indicate dirty air vents, which can also be a major source of indoor air pollution. Air vents are known to accumulate dust, dirt and other debris that can be circulated throughout your building. This can contribute to or exacerbate a variety of health problems among your employees or customers, including allergies, asthma and other respiratory issues.

It’s important to have your air vents regularly cleaned to ensure that the air quality in your commercial space isn’t compromised.

Something Is Stuck in Your Heating System

When something flammable or meltable is stuck in the heating system, it can cause a burning smell to come from your vents. This smell is usually caused by something lodged in the system burning off or melting as the heater runs. The smell can be quite strong and unpleasant, and it may be accompanied by smoke. If you notice this smell coming from your vents when your furnace is operating, it’s important to turn off the system immediately and contact a professional for help. An HVAC technician can inspect the system and remove any debris or objects that may be causing the issue.

Electrical Issues

If you think you smell the odor of burning plastic coming from your furnace, the source may be an electrical issue in your heating system. This is likely a serious matter and it’s important to take action immediately.

One of the most common causes of a burning plastic smells coming from a heater is a short circuit. This occurs when a hot wire touches a neutral wire, creating an overload of electricity that causes the wires to heat up and melt the insulation around them. This can create a burning smell that resembles burning rubber or plastic. If you notice this smell coming from your heater, turn off the power immediately and contact an HVAC technician who can inspect the wiring and determine the best course of action.

The Benefits of Preventative HVAC Maintenance

Thu, 27 Oct 2022 02:48:21 GMT

5 Benefits of Preventative HVAC Maintenance

As a business owner, doing everything you can to save money and improve the condition of your property is extremely important. That’s why at Tom’s Commercial, Inc. we are proud to offer commercial HVAC maintenance for a range of properties. Commercial heating and cooling systems often contain advanced technology, and it takes a qualified professional to handle all their components and parts. Fortunately, our commercial HVAC experts have almost 60 years of experience, meaning you can always count on us to keep your property safe, comfortable, and efficient. Keep reading to learn all about the top five benefits of preventative HVAC maintenance, and make sure to call Tom’s Commercial, Inc. for all your business’s comfort needs.

1. Improved Efficiency

When it comes to all things heating and cooling, efficiency is the name of the game. For a system to operate at maximum efficiency, it requires annual inspections, tune-ups, cleanings, and other maintenance work. In general, it has been found that properties that receive periodic maintenance are 15-20% more energy-efficient than properties that don’t.

With the right maintenance technician, your property can prevent energy loss through air leakage, changes in climate, and system malfunctions. Schedule annual maintenance for your commercial business today, and start enjoying more comprehensive heating and cooling relief throughout your property.

2. Lower Energy Bills

Better energy-efficiency and lower energy bills go hand in hand. As your commercial HVAC equipment ages, it is natural for it to have to work harder to accommodate your property’s needs. This will result in higher heating and cooling bills for you. However, studies have found that through basic maintenance like coil cleaning, you may be able to slash certain energy-related costs by an average of 17%.

While it is true that modern HVAC equipment is far more energy-efficient than the systems that were on the market 30 years ago, maintenance is important for old and new equipment alike, especially if you want to maximize energy savings.

3. Fewer Repairs

Even more frustrating than standard HVAC operating costs are the expenses related to heating and cooling repairs. With preventative maintenance, you can catch potential problems with your commercial HVAC system before they spiral out of control, saving you a lot of money over time. No business owner wants to have to shut down temporarily because they have to close for repairs. Hire a commercial HVAC company for maintenance, and you can avoid this and save more money in the long run.

4. Longer System Lifespan

While you may want to upgrade your old HVAC system to a more energy-efficient model eventually, it makes sense to get the most you can out of your current heating and cooling equipment. The best way to do this is through annual maintenance. In most cases, the cost of maintenance far outweighs the price you will pay for early replacement. Consider that if you have a system that costs $10,000, and you spend as much as $10,000 maintaining it over its 10-year lifespan, you will still have only spent $20,000 on total HVAC costs over the course of a decade.

However, if you did not properly maintain the unit, and it failed at the 5-year mark, you would need to spend another $10,000 to replace it—meaning that it cost you the same amount of money in half the time. Changing your HVAC equipment’s oil, replacing belts and filters, and hiring a technician for general cleaning and other maintenance tasks goes a long way towards preventing this from happening,

5. Greater Environmental Benefits

If you are a business owner who is at all concerned with being eco-friendly, there’s no question that scheduling preventative HVAC maintenance is better for our planet. Around the globe, the cooling industry produces an unnecessary emissions value of 500 million metric tons of CO2 equivalent (CO2eq) annually.

By optimizing and monitoring our HVAC systems, the U.S. alone could slash this amount by 5 million metric tons of CO2eq a year. So as a responsible business owner that is trying to save money on energy costs and do something good for the Earth, it’s hard to argue with the benefits of preventative maintenance.

6. Improved Indoor Air Quality

Did you know that preventative HVAC maintenance can help to improve indoor air quality? If you or your employees suffer from asthma or other respiratory illnesses, preventative HVAC maintenance can significantly help to reduce symptoms. Preventative HVAC maintenance can also help to eliminate the spreading of airborne allergens. Indoor allergens can carry airborne particles such as dust mites, pollen, mold, and cigarette smoke, and more, which can pose serious health concerns. Regular HVAC maintenance typically includes services such as air duct cleaning, which can help to create a cleaner breathing atmosphere for you and your fellow employees. Contact us to learn more about the many benefits that preventative HVAC maintenance has to offer and about what we can do to make your business a healthier and better place for you today.
