Changing Your Home Air Filter

Last updated 4 years ago

There are a lot of things that can go wrong in your air conditioner without proper maintenance, but regularly replacing the air filter is by far one of the easiest and most effective preventative maintenance measures. Some air filters are capable of removing allergens from the air, but their primary purpose is to prevent dust and debris from getting into the sensitive components of your HVAC system.

Simply locate the air intake vent (usually near the ceiling or in the furnace), remove the grate, and replace the dirty filter with a clean one, ensuring that the arrows on the sides are pointing the correct way. The frequency of air filter changes varies depending on location and inclement weather, but it’s generally recommended to check them at least once a month and to replace them at least every three months.
