How do I change an AC system filter?

by | Dec 28, 2018 | AC Repair, FAQ, Tutorials

Modern central heating and air conditioning systems generally have the filter located as close to the blower unit as possible. The filter(s) can be located at the base of the air handler/furnace unit, in the cold air return duct located in your ceiling or on your wall.

Remove the grill or box cover holding your filter in place.

Remove the dirty filter:

Dispose of the dirty filter in a bag to contain the dust.

Install:

Install the new or cleaned and dried air filter with the air flow arrow pointing toward the blower. Record the date and wash or change the filter within the recommended period. If you experience higher dust levels in your home due to changes in outside air, construction or dry weather, you may need to change or wash your filter more frequently than the recommended period. For questions or concerns about the location or installation of the filter contact the HVAC manufacturer or give us a call. As a reputable HVAC contractor we can make recommendations that are right for both you and your system.
