HVAC Preventative Maintenance Checklist

Preventative maintenance by a qualified HVAC technician every spring and fall is the best way to not only keep your home’s heating and cooling systems running and functioning properly, but also to prolong the life of your total system and see big savings on your annual energy bills. Here is a partial checklist of items, some of which most people can handle, but the rest often goes beyond the knowledge and experience of the average homeowner and requires qualified technicians to perform.

What You Can Do to Help Maintain Your HVAC System

  • Purchase and utilize high efficiency pleated air filters. These filters have an electrostatic charge that acts like a magnet to catch and hold tiny airborne particles, many of which carry bacteria.
  • Replace air filters every 90 days, more often if you have pets.
  • Check thermostat for proper home and away settings.
  • Check controls for proper and safe operation by starting cycle at the beginning of the heating and cooling seasons by turning the system on, let run, then shut off.
  • Verify no more than 20% of the registers in your home are closed to avoid unnecessary strain on the system.
  • In the summer, turn off water supply to furnace humidifier. In the fall, replace humidifier filter and turn water supply to humidifier back on, with settings at a suggested 35% to 40% humidity.
  • Replace carbon monoxide detector batteries and ensure proper operating status annually.
  • Keep the tops and sides of outdoor units free of debris such as leaves, pollen, and grass clippings.
  • Maintain two feet of clear space around outdoor units and ensure they are on solid and level ground.
