Customer Review

Despite Frigi-Temp’s location in the temperate climate of Raleigh Durham, we still see problems caused by the ravages of winter. After all, it only takes one storm to cause chaos, such as through the right mix of sub-zero temperatures, wind, rain or snow. These conditions damage mechanical parts, particularly in your commercial HVAC system.

The last thing anyone wants is a heating emergency. This affects company revenue, employee comfort, customer care and the overall productivity of any business, at the least. It also causes incredible, unforeseen expense.

Learn some tips below for winterizing your commercial HVAC system. These tips help you prepare for keeping your people, property and equipment warm during that one bad storm in RDU this year. By taking care of your systems and performing some checks in fall, bigger problems do not occur over the holidays or in the coldest months of the year. Through proper winterization, you also save money on monthly heating costs and emergency maintenance.

1. Properly Inspect Your Commercial HVAC System

If your commercial property has a knowledgeable party on-site who can inspect your HVAC systems, that is great. But most companies cannot afford to rely on an internal specialist. Calling in the experts for a winterizing commercial HVAC preventative maintenance inspection is a smart move.

Frigi-Temp performs winterizing inspections of your HVAC systems. These inspections provide eyes-on examination of coils, pipes, faucets, hoses and other parts near, contacting or using water or outside air. These checks prove essential as temperatures drop, water freezes and storms roll in.

Winterizing inspections of HVAC systems include:

  • Evaluation for proper operation
  • Correct setting of freeze stats to protect coils
  • Checking for cracks in the heating system
  • Inspecting blower and hose quality, including for blockages
  • Listening for abnormal sounds
  • Emptying condensation traps
  • Cleaning air vents
  • Monitoring air flow

2. Inspect Your Plumbing

To clarify, it only takes one frozen pipe to wreak havoc on your business’ daily operations and profitability, through HVAC breakdown and even extensive asset damage. A good winterization of your plumbing includes:

  • Checking exposed and exterior pipes for freezing vulnerability
  • Insulating and sealing openings around exposed pipes
  • Looking for signs of moisture or condensation
  • Checking for mold or mildew growth

Therefore, finding signs of problems in any of these areas requires your prompt attention for repair. After all, weather is unpredictable and your next winter storm of the century could happen any day.

3. Inspect Your HVAC Systems

One of the biggest threats to your business and the people inside it during winter is a cracked heat exchanger. One crack can leak deadly carbon monoxide into your facilities. This highly fatal, but invisible and odorless, gas kills many people each winter. Any fall inspection of commercial HVAC systems must look for these cracks.

Besides closely inspecting the heat exchangers for signs of cracks, your inspection of the heating system should include:

  • Confirming proper operation for safety settings
  • Removing and cleaning burners
  • Ensuring burner flames are burning clean
  • Checking flue ventilation
  • Calibrating water gauges
  • Checking expansion tanks for adequate air cushion
  • Cleaning boiler tubes

4. Inspect Airside Economizers

Most HVAC systems feature an airside economizer. This allows your HVAC system to utilize outdoor air to cool, based on indoor humidity and ambient air temperature. This outdoor air cooling process is called free cooling, as it does not rely on a compressor. If this component disables or does not work properly, your system leaks warm air or pulls in too much cold air. This results in astronomical energy bills.

Of course, a Frigi-Temp winterizing inspection of your systems checks your airside economizer for proper functioning and absence of leaks.

5. Calibrate Thermostats and Reduce Settings

Even modern digital thermostats skew from correct readings over time. Uncalibrated thermostats also affect your HVAC systems efficiency, particularly causing simultaneous heating and cooling. Frigi-Temp calibrates your thermostat, reduces settings and ensures all systems read properly.

6. Change HVAC Filters

Changing air filters is essential for maintaining good quality of air inside your property. These filters catch airborne particles and dust for both heating and cooling. But air quality is not the only problem when you leave filters unchecked and dirty. Your bottom line also suffers, as an old filter increases the cost of operating your HVAC, no matter the season. Dirty filters also lead to damage of HVAC fans and compressors, as these parts cannot operate efficiently.

In places where heating and cooling are critical, such as for food storage, clean rooms and data centers, or pharmaceutical facilities, additional inspection scrutiny is particularly important. These inspections must check head pressure controls, fans, thermostatic fan control calibration and humidifiers.
