If you haven’t changed a furnace filter before, it might seem like a daunting task, but it isn’t that complicated. This guide will give you the ins and outs of performing this important change.
If you have the manual, you can find the location of the filter for your furnace. If not, look for it either in the furnace unit or a nearby air vent. Once you locate it, use a permanent marker to draw an arrow showing which way the airflow goes. This will help you put the new filter in the right way.
Slide-out the filter. If it has a plastic frame, then the filter is reusable. Clean it off using a vacuum and then water, letting it thoroughly dry before re-inserting it. If it has a cardboard frame, it is meant to be replaced.
The filter should have numbers on it showing its size. If not, the furnace manual will have this information. It can be helpful to note the size of the filter with a permanent marker on the furnace. You can buy a new filter in hardware stores, home centers and online.
There are different filters available. A basic filter traps dirt, dust and airborne particles. An advanced filter also traps mold spores, pollen, and bacteria.
When you have your furnace serviced, the HVAC company will likely replace the filter. Above and Beyond Heating & Cooling in the Oklahoma City area replaces filters during our tune-up service.
Note the direction of the arrow you drew and place the new filter incorrectly. Filters are designed to trap particulates on one side, so it’s important to make sure they are placed in the correct direction.
