You may have heard or seen us say at one point that it’s important to change out your HVAC air filter every 1–3 months. We aren’t just throwing this out as a random suggestion. We are offering this tip as a way for you to get the most effective and most efficient use out of your furnace or air conditioner. And considering how much we have to use both around here, chances are you’d like to do anything to keep your heater running powerfully and affordably, right?
Well, one method of doing this is by performing a small maintenance task—changing the air filter. You might be surprised to find just how important this small component is. It’s about much more than protecting or improving your home’s indoor air quality. In fact, that is not the purpose of this air filter at all. While there are whole-house air filtration systems available to improve IAQ, the furnace air filter is in place to protect the furnace itself from debris that can get inside and damage its components.
