Units located in the attic Open the return grill to access the filter. The grill is just below the attic in the ceiling. Some units also have a fresh-air intake. If yours does, change the fresh-air filter, too. It’s in the return grill.

Filter Change or clean the air filter monthly to ensure maximum efficiency. A clogged filter can cause a malfunction in the heating and cooling unit. Check the system manufacturer’s instruction manual for the filter location, and how to change or clean it. Turn off the unit before attempting to change or clean the filter. Use only the size and type of filter the manufacturer specifies.

Insulation Your home is insulated properly for the climate in which it’s located. If your home’s heating or cooling is inadequate, it may not be due to inadequate insulation. More likely culprits are open doors and windows, clogged filters, register misuse, or inadequate window coverings. Cooling coils Check for a dirty filter if your air conditioner freezes up. If the filter is clean, turn off the air conditioner and wait for the ice to melt. Call a technician if the freezing continues.
