With the cold months approaching, you have two options to ensure your facility is well-equipped for business operations during the winter season.
- Take steps now to be sure your heating system is ready to go.
- Field a ton of complaints later about the ice-cold lunchroom.
The headache — and cost — of responding to these issues in the middle of winter? Avoidable.
Commercial HVAC maintenance offers a straightforward way to keep your facility comfortable, safe, and efficient while preventing the need for costly repairs during peak demand.
What’s your facility’s current strategy for winter maintenance?
Taking proactive steps now prevents chaos down the line and ensures every dollar spent on heating counts.
According to the U.S. Energy Information Administration, commercial heating and air conditioning systems account for nearly 45% of a building’s energy consumption, and space heating alone accounts for 32%. This demonstrates the importance of optimized heating for operational efficiency. When systems run smoothly, energy use remains predictable and manageable.
Winter weather demands a readiness plan that’s as practical as it is preventive. Below, we’ll outline the essential steps to winter-proof your facility.
Why Preventive Commercial HVAC Maintenance is Your Best Investment
Managing costs and preventing unexpected issues should be a top priority for any business owner or facility manager. Proactive HVAC maintenance is one of the smartest investments you can make to avoid expensive repairs and keep energy bills predictable.
As we mentioned above, HVAC systems typically make up about 45% of a commercial building’s energy use. That means even a small efficiency boost has a noticeable impact on your bottom line. Maintaining an efficient HVAC system can directly impact your operating budget.
Here in Tennessee, commercial electricity rates are about 12.13 cents per kilowatt-hour (kWh). Consider a small office building using around 10,000 kWh of energy per month. With minimal or no maintenance, its monthly energy cost would be about $1,213 (not to mention the added cost of emergency repairs due to neglected maintenance).
A 10% efficiency boost from regular maintenance drops their energy use to 9,000 kWh monthly, reducing the annual cost to about $13,100. This translates to a yearly savings of $1,456, which easily covers the maintenance cost itself.
Looking at the bigger picture over five years, the facility without maintenance would spend approximately $72,780 on energy. However, with maintenance maintaining a 10% efficiency improvement, this cost drops to about $65,502 over the same period. That’s a total savings of nearly $7,278 — money that can be reinvested back into the business.
Understanding Your Commercial HVAC System and Seasonal Wear and Tear
After months of keeping your building cool through Tennessee’s sticky summer heat, your commercial HVAC system has likely accumulated some wear and tear. As winter approaches, the strain shifts to your commercial heating system, often revealing inefficiencies that may have gone unnoticed. Cold weather puts additional pressure on the system, making now the ideal time to assess and address potential energy losses before they hit your bottom line.
Winter is also the time to consider how ductwork affects your energy use. Leaky or poorly insulated ducts can lose 25-40% of heating energy, significantly impacting your monthly expenses. Even a well-maintained commercial heater or furnace can struggle to keep up if energy seeps through compromised ducts.
Snow and ice buildup around external components of your HVAC system can also negatively impact its performance. Regular maintenance keeps these areas clear and functioning correctly, leaving you with a comfortable and efficient facility.
Signs Your Commercial Heating System Needs Attention
As winter sets in, your commercial heating system can reveal signs of strain that, if ignored, might lead to costly breakdowns and dips in productivity. Catching early warning signs can save you the hassle of unexpected repairs and help keep your building consistently comfortable.
Different commercial heating systems — from large boilers to rooftop units to heat pumps — all have unique warning signs that reveal underlying inefficiencies. The following are common signs your system may need attention:
Inconsistent Temperatures Across Zones
If you’re hearing complaints about cold conference rooms while other areas stay warm, you may have duct leaks or zoning issues. For buildings with complex zoning, an aging or poorly maintained commercial furnace may struggle to distribute heat evenly.
Unusual Noises
Banging or hissing sounds in a boiler system often signal issues like trapped air or sediment buildup. For rooftop units, rattling may indicate a misaligned blower motor. When parts wear out in rooftop systems, they’re particularly vulnerable to winter’s harsh elements, making these noises a clear indicator that preventive maintenance is overdue.
Sudden Spikes in Utility Bills
A monthly increase without a change in usage patterns typically points to inefficiencies. For example, a rooftop unit struggling to meet heating demand might run longer and harder, consuming more energy. Contacting a professional commercial HVAC contractor for an efficiency checkup can reveal if you’re dealing with a mechanical issue, leaky ducts, or system overuse.
Poor Indoor Air Quality
Lingering dust or musty odors could indicate clogged filters or dirty ductwork, which forces your system to work harder to push warm air throughout the building. Poor air quality doesn’t just affect comfort in a commercial property—it can trigger complaints from tenants or employees, especially in facilities with sensitive equipment or inventory.
In the commercial setting, even a few hours of downtime can disrupt business operations, affect tenant satisfaction, and potentially cause revenue losses. Are you ready to proactively manage these issues before they impact your building’s bottom line?
The Benefits of a Pre-Winter Heating System Inspection
We’ve already touched on the most significant benefit of regular heating system maintenance — efficient energy use and related costs. However, a pre-winter inspection also has other advantages that can directly impact the success of your business.
Improved Comfort
Maintaining a comfortable indoor environment is crucial if your business is customer-facing or your building is solely for employees. A restaurant with temperature fluctuations may see a decrease in customer satisfaction, while an office building with cold spots can lower employee morale and productivity. Regular maintenance keeps temperatures consistent throughout the building.
Extended Lifespan of Equipment
Commercial HVAC equipment can easily last 10 to 20 years if properly cared for. Regular maintenance extends the lifespan of your system, helping you avoid premature replacements and unexpected expenses.
Safer Operation
Commercial heating systems, especially those that use natural gas or propane, require regular maintenance to ensure safe operations. A pre-winter inspection can reveal potential safety hazards, like gas leaks, that could put your building and occupants at risk.
Reduced Emergency Repairs
Preventative heating system maintenance reduces the likelihood of emergency breakdowns, which are not only inconvenient but also costly. When heating systems fail unexpectedly, emergency commercial HVAC repair costs can soar, with rates often doubling or tripling during peak winter demand.
Worse, sometimes repairs aren’t enough, and a neglected system may require a full replacement, which may cost five or even six figures, depending on your facility’s size.
Beyond that, unexpected downtime across all industries costs around $9,000 every minute. Are these expenses your business can afford? Routine maintenance practices are a great way to maximize building uptime.
Better Indoor Air Quality
Poor indoor air quality can aggravate cold and flu season, adding to the $2,945 per employee that U.S. employers lose each year due to illness and presenteeism. Regular maintenance includes changing filters and cleaning ductwork to keep the air you breathe fresh and healthy. It also reduces the buildup of dust and allergens that can circulate throughout your building.
Regular, preventive commercial HVAC maintenance helps avoid these costly issues while keeping energy bills predictable. Facility managers who proactively plan for seasonal demands often see the benefits in their bottom line and a smoother winter season. Will your facility be ready for the demands of winter, or are you waiting for a costly breakdown?
What to Expect in a Commercial Heating System Inspection
A commercial HVAC inspection is a crucial step in preparing your facility for the winter months. While the specific tasks may vary depending on the size and type of system, a professional technician will typically focus on the following:
- Heat Exchanger Check: Inspecting for cracks or corrosion to prevent carbon monoxide leaks and ensure energy efficiency in high-use systems.
- Gas Leak Detection: Testing gas connections and pressure to identify leaks, reducing both safety risks and utility costs.
- Burner Assembly Cleaning: Removing soot buildup to maintain safe, efficient combustion, which is essential for high-output commercial heaters.
- Ignition System Testing: Ensuring reliable startups for systems that must run consistently in cold weather.
- Air Filter Replacement: Replacing filters to improve airflow and air quality, which is particularly important in high-traffic facilities.
- Ductwork Inspection: Identifying blockages, leaks, and insulation issues to prevent heat loss and improve efficiency.
- Airflow and Thermostat Calibration: Balancing airflow and calibrating thermostats for consistent heating across zones.
- Electrical and Moving Parts Check: Inspecting electrical connections and lubricating moving parts to prevent wear and potential hazards.
- Safety Controls Evaluation: Testing operating efficiency to identify potential problems and prevent emergencies.
In facilities that rely on industrial chillers, winter preparation includes additional specialized tasks. While not all chillers operate during colder months, those that do require careful maintenance to prevent damage from freezing temperatures:
-
Check Glycol Levels: Using a refractometer, verify that the glycol mixture is appropriate for expected cold temperatures. Adjust concentrations as necessary to protect the system.
- Inspect Piping Insulation: Properly insulated pipes prevent heat loss and reduce freezing risks, ensuring system integrity during harsh weather.
- Test Freeze Protection Systems: Confirm heat tape and freeze protection thermostats are working correctly to prevent ice buildup in critical components.
- Monitor Pumps: Ensure pumps function properly and are set to activate automatically when temperatures drop below freezing. Continuous water circulation is key to preventing freezing.
- Adjust Head Pressure Controls: Modify the head pressure controller or fan cycling switches to maintain appropriate high-side pressures for optimal performance.
Including industrial chiller maintenance in your pre-winter inspection ensures these critical systems remain efficient and operational, protecting your facility’s productivity and energy efficiency.
A comprehensive inspection addresses these components and primes your heating system—and any associated equipment like chillers—for the winter. But today’s facility maintenance goes beyond traditional methods. Technology now plays a critical role in improving inspection accuracy and efficiency.
