How can you replace the air filter of the furnace yourself?
If you haven’t done this before, you might not have any idea of where the air filter is located. Please don’t procrastinate replacing the filter, as this will only increase impurities in the indoor air as well as shorten the life span of your furnace.
To replace the air filter, simply open the tray at the bottom of the furnace that has an air filter sign. Soon as you open it, the air filter should slide out along with it. Put the new one in the correct direction. Also ensure you are replacing the old filter with the one that’s the correct size.
