Changing your furnace air filter is one of the quickest and easiest ways to maximize the efficiency of your heating system and purify the air in your home. It's important to check your filter once a month and replace it if you can't see the light clearly when you hold it up. Here's a step-by-step guide on how to change your furnace air filter. First, turn off the oven. Then, remove the existing filter, which is located just inside the oven or inside the return air vent.
Use a sticky note or permanent marker to mark the direction of air flow outside the oven. This will maintain airflow through the oven, minimize strain on the heating system, and help filter dust and other particles out of your home's air. Next, measure the air duct if you see that the filter in place is too small or too large. Take three measurements: the depth of the return air duct, the height and width of the space in which the air cleaner slides. If you don't have the operating manual for your unit, most air filters are located in the blower compartment of the oven (remove the oven cover, usually lifting it up) or integrated into the metal duct network before the blower fan. You may not believe it, but the air filters are located inside the indoor unit, just below the front panel.
Specifically, you should replace your oven filter on a regular basis, which means approximately every three months. If you haven't already figured it out, a downflow configuration means that your downflow air controller or oven blows cooled or heated air down. Finally, place a new filter and turn on the oven again. You may think that you only need to change the oven filter once a year, but this can cause the oven to work too hard, overheat, and shut down. Owning a home is exciting, but it requires a bit of DIY maintenance that isn't always as exciting as changing a furnace filter.
