How Often Should I Change My Furnace’s Filter?

Posted on: October 18, 2016

Most homeowners expect their furnace to work at the start of each winter with the mere press of a button. Though furnaces have become quite the remarkable pieces of technology, they still require some regular maintenance! Your furnace’s filter is crucial to your unit’s functionality. It must be changed regularly in order to keep the furnace operating at peak efficiency.

But “regularly” seems pretty vague, right? That’s why we wanted to nail down how often you should really be changing your filter to maximize your furnace’s efficiency and performance.

Why It’s Important to Change Your Filter

Would you like to increase your furnace efficiency by up to 15 percent? According to the U.S. Department of Energy, simply changing the filter at the appropriate interval can improve the system’s efficiency by that amount! This is thanks to the fact that dirty furnace filters prevent a steady stream of air from passing through the system and into your living space.

A clean filter will allow the furnace to work as designed. In contrast, a dirty filter will tax the system, forcing it to work much harder than it should have to. In the end, switching out your old filter for a new one has the potential to save you hundreds of dollars every year. Those are some serious savings!

Changing your furnace filter will also improve the quality of your indoor air. If you leave a clogged filter in place, it will make it difficult to trap additional dust, grime, and other unsavory particles. As a result, some of those nasty particles will make their way through your air ducts and into your home’s air.

It is also important to consider the fact that a dirty furnace filter increases the odds of a repair. Since dirty filters force the system to work much harder than it should, the furnace will endure extensive wear and tear. This heightens the chances of a breakdown and consequential repair. Add in the fact that an overtaxed furnace won’t last nearly as long as it should and it is easy to see why some homeowners switch out their system’s filter once per month just to be on the safe side.

When Should You Replace Your Furnace Filter?

If you were to poll a group of HVAC professionals about the proper frequency for your system’s filter replacement, they would testify that it hinges on an array of factors like the number of people in the home, whether pets are present, the type of air filter, the home’s air quality etc.

Though you don’t have to change your furnace filter every single month, it should be changed every three months at most, as the seasons change. So, be sure that your furnace filter is switched out at the start of winter, fall, spring and summer! When in doubt, we suggest that you check the filter to see if it is truly dirty.
