When we advise our customers to replace their HVAC air filter every 1-3 months, we’re not just offering a general recommendation. We’re offering this advice as a way for you to get the best performance and the most effective use out of your HVAC system as possible. And considering how much you’ll need to use your heater in the coming months, chances are you’d like to do anything you can to lower your energy costs while doing so.
One way to do this is by performing one small “DIY” maintenance task—changing the air filter. You might be surprised to find just how important this component is. It’s about much more than protecting your indoor air quality. In fact, that’s not even the main purpose of the air filter—it’s in place to protect the actual HVAC system itself. More on that below.
