What’s the tee-total most important thing you can do to maintain your HVAC system? Change your filters monthly! It’s simple, it’s cheap, and it’s critical.
I am still amazed at the deleterious effects of a dirty filter…yet I have a hard time remembering to do it in my home…a monthly note on my calendar has helped.
A dirty filter equals a system that can’t breathe, struggling to get the air it needs to function. As the system struggles more and more, strain is placed on…everything…within the system.
But wait, it gets worse–once a filter gets dirty enough, the particulate matter it is designed to catch starts passing through to your evaporator coil (which is the heart of your indoor uniit). Dirt in this coil is bad…very bad. Cleaning an evaporator coil isn’t cheap, and there’s always the possibility that too much damage has occurred and it has to be replaced completely. I’ve actually seen filters that got so clogged that they folded in on themselves and got sucked right to the coil. Not good….
You don’t need to purchase the fancy jobbies that tout baking soda or allergen fighters (these additives can actually reduce the effectiveness of the filtration)–just basic poly filters will do. With monthly changes it’s all you need.
Filter changes–it’s simple, it;s cheap, and it’s critical–same money, change monthly! Visit us at www.comfortheatingandac.com for more DIY tips!
