Changing Your Air Filter

Changing Your Air Filter


Regularly changing your HVAC air filter helps keeps it running efficiently, which saves you money on your electricity bill and also lengthens the life of your HVAC system. The filters need to be changed once a month or once every 3 months, depending on your system. Changing the filters also maintains the warranty on your system.


1. Locate the air returns for your air conditioner. There may be multiple returns throughout your house, so be sure to check upstairs as well as downstairs. Pull the filter compartment out of
each return.

2. Measure the filter’s outer dimensions, and look for any identifying numbers or letters on the casing. Each return may have a different size filter.

3. Once you’ve bought your new filter(s), turn off the unit and slide the filter into the air return the same way the old one came out.

a. Make sure the filter is placed into the compartment with the correct side facing out.

b. Follow the directions on the package. The sides are usually marked as air-in and air-out.

4. Replace any filter cover or door that you took off to gain access to the filter compartment.
