Is your heating system ready for the coldest months of winter? With commercial HVAC systems it is necessary to do a bit of maintenance to ensure everything is working properly and efficiently.

Winter weather and freezing temperatures can wreak havoc on your system if you’re not prepared, and that can result in heating system failure at an inopportune time. Here are the most important steps to take in order to winterize your commercial HVAC system. 


Perform a Thorough Inspection

Start by inspecting the entire heating system, including every part that is indoors as well as outdoors. Go through the following list:

  • Check exposed pipes for proper insulation. Pipes that lack insulation can freeze and cause all sorts of problems. 
  • Look for signs of moisture or leaks. Moisture where it shouldn’t be usually indicates a leak that needs to be fixed. 
  • Check for cracks in any part of the heating system or ductwork. Cracks allow heat to escape outside rather than warming the inside as it should. 
  • Empty condensation traps. Condensation accumulates and will freeze in cold temperatures, potentially causing problems. 
  • Ensure there are no blockages in hoses or drainage tubes. Condensation needs to be able to drain out and the flow of air in both directions should be unencumbered. 
  • Listen for unusual sounds. If your system is making strange or louder than usual noises, there could be a part that is wearing out or some other mechanical issue. 


A thorough inspection can go a long way toward making sure there are no unexpected surprises. 


Basic Maintenance

Here are the most basic maintenance steps that should be done multiples times a year:

  • Replace the filters. Dirty, clogged filters are one of the most common problems with HVAC systems. Changing filters regularly keeps your system operating efficiently. 
  • Check carbon monoxide detectors. Many furnaces and heating systems produce carbon monoxide. If not properly ventilated, CO detectors are an important safety feature. 
  • Calibrate thermostats. Thermostats can sometimes deviate from their original temperature gauges, causing incorrect readings and operation of your heating system. 
  • Clean ducts and vents. Keeping ducts and vents clean will go a long way toward maintaining the efficiency and proper operation of your HVAC system. 


Professional Maintenance and Tune Up

Unless you are in the HVAC business, there are aspects of yearly maintenance that should only be handled by a professional. Depending on your level of comfort and expertise, you may even need an HVAC specialist to perform some of the items listed above. At the very least, it is necessary to have a yearly inspection and tune up for your heating system performed by a professional commercial HVAC technician.
