Where do I change my air filter for my air conditioning system?

 

There are several places that an air conditioning system filter can be located. The most common place is in a filter rack near the furnace. You will see a little door near the furnace inlet. If you don't see the door, the filter may be INSIDE the furnace itself. Sometimes furnaces have a small filter rack located just inside the furnace doors. You may want to call your air conditioning company to either replace it for you or show you how to properly and safely change out the filter in this situation. Another place the air filter may be located is in the ceiling or wall inside a return air filter grill, and there may be more than one filter grill for each system so make sure you locate and change all filters.
