Preventative Maintenance is Crucial to Keeping a Commercial HVAC System Running Smoothly!

Having your commercial HVAC system professionally serviced on a regular basis can help improve its function and extend its lifespan, while allowing you to realize significant cost savings thanks to the resulting more efficient workings of the system. At a minimum, you should have preventative maintenance performed on your business’ HVAC system at least once a year, though scheduling maintenance twice annually–typically when the weather changes from cold to hot and back again–can help ensure that your system stays in top working order. Here’s what your HVAC technician should be doing in each seasons’ maintenance visit.

Spring or Summer Commercial Air Conditioner Maintenance Checklist:

Getting professional preventative maintenance performed on your system before warm weather fully hits can help ensure that you have air conditioned air when you need it most. In your spring or early summer maintenance visit, your HVAC technician will:

  • Replace any clogged filters on the cooling equipment;
  • Inspect the condition of pulleys and belts, replacing if necessary;
  • Clean the evaporator coils and condenser;
  • Check the refrigerant levels, adding refrigerant and examining for leaks if the levels are low;
  • Clean out drain lines;
  • Check any electrical connections;
  • Examine the operating condition of the blower motor and fan, performing adjustments and replacements as needed;
  • Ensure that the motors, bearings and any other moving parts are adequately lubricated;
  • Confirm that the thermostat is working properly; and
  • Confirm that there’s adequate air flow through all ducts.
Fall or Winter Commercial HVAC System Maintenance Checklist

When entering fall, the major purpose of preventative HVAC maintenance is to ensure that all components that contribute to its heating function are in good shape and not in need of repair or replacement. Your HVAC maintenance technician will:

  • Replace any clogged filters on the heating equipment;
  • Inspect the condition of pulleys and belts, replacing if necessary;
  • Check the strength of all electrical connections;
  • Clean out any drain lines;
  • Examine the operating condition of the blower motor and fan, performing adjustments and replacements as needed;
  • Check the condition of the burner assembly and ignition;
  • Ensure that the motors, bearings and any other moving parts are adequately lubricated;
  • Confirm that the thermostat is working properly; and
  • Examine the heat exchanger.
