Replacing your HVAC air filter is one of the major jobs that you can perform for your system maintenance. Unfortunately, not too many homeowners do so because they find it difficult or just forget about the air filter as it’s out of sight. Bear in mind that the dirty or clogged filters will result in a higher electricity bill or expensive repairs, which can cost you more than just getting a replacement filter.
