HVAC Maintenance Checklist

Every fall and spring, you should have your HVAC system inspected and maintained by a professional HVAC company. They will perform tasks that are a little more difficult for the typical homeowner, like inspecting and cleaning the wiring and mechanisms of the air conditioner and furnace.

Here is a simple, attainable checklist for preventive maintenance to maintain your heating and cooling system in top shape.

10 Steps to Extend the Life of Your HVAC

✔️ If you haven't already, invest in a quality filter. The brand-new high-efficiency pleated filters include an electrostatic charge that functions as a magnet to pull in even the smallest particles, including bacteria-carrying ones.

✔️ At least once every 90 days, replace the filter. However, do so once a month. Change it if it appears to be black and congested. If you have pets, you should definitely replace it every month.

✔️ Make sure there is at least two feet of space between outdoor heat pumps and air conditioners.

✔️ In the spring, summer, and fall, clean the top and sides of outdoor air conditioners and heat pumps on a weekly basis to remove debris like leaves, pollen, and twigs. Don't let the grass clippings from the lawnmower fall onto the appliance.

✔️ Check the insulation on the refrigerant pipes entering the house once a month. Replace any damaged or missing lines.

✔️ Check that the unit is level. Ensure that outdoor air conditioners and heat pumps are placed on solid, level ground or pads once a year.

✔️ Prevent clogs. Pour a cup of bleach and water into the air conditioner condensate drain once a year to prevent the growth of mold and algae, which can clog the drain.

✔️ In the summer, turn off the water supply to the furnace humidifier. Replace the humidifier wick filter in the fall (or when you plan to turn on the heat), set the humidistat to between 35% and 40% relative humidity, and turn on the water supply.

✔️ Never close more than 20% of the registers in a house to prevent unnecessary strain on the HVAC system.

✔️ Replace the battery in your home's carbon monoxide detector annually.
