How to Change a Furnance Filter

How To Change A Furnace Filter (courtesy of Dummies.com)

Dust, dirt, carpet fibers, pet dander…these are all of the things your furnace filter takes out of the air, to help keep your house cleaner, and help keep allergies under control. When your filter is working hard, your furnace is really efficient. And, without all that stuff in the airflow, the blower motor lasts longer. The filter also prevents the compressor coils from getting clogged. So, you’ll want to change the filter regularly.

Buy furnace filters a case at a time. It’s cheaper that way. Open the case, and label each one with the date that you plan to install it. Changing the filter is easy!

First, open or slide the door panel to get access to the furnace. You usually find the filter near where the cool air enters the furnace, in the cold air return duct, or at the entrance to the blower chamber. Or, sometimes, in both locations!

Next, slide out the old filter, and replace it with the new one. Make sure the airflow arrows on the side of the filter are pointing the right way – toward the blower, and away from the cold air.

Now, replace the panel or door.

Furnaces need attention, so you want to replace the filter every month during the heating season. And, if you have air conditioning in the system, then change the filter every month all year long.

A little preventive care increases the life of your furnace, and makes your house cleaner and fresher!
