To-Do #1: Replace Furnace Air Filter
The air filter on your HVAC (Heating, Ventilation and Air Conditioning) system needs to be replaced every 1-3 months to keep the air in your home clean and flowing freely. A high quality air filter is the best choice to remove mold, pollen, and other microscopic particles from the air.
The air filter is usually found behind the air return grate mounted on a wall or in the floor. The filter may also be located in or near the air handler. Check out our article on How to Locate an Air Filter if you can’t find yours.
To replace an air filter:
- Turn the heating system off, and wait until it stops running.
- Put the cover back on the air return.
To make it easier to replace next time, put a sticker on or near the return with the size filter you need to buy and when to replace it.
