3 Ways to Know When It's Time to Change Your Furnace Filter This Winter

Pet Dander

Maintenance agreements take the guesswork out of the equation, but if you don't have one, you'll need to be sure your filter's still doing its job. A furnace filter is one of your home's first (and most important) defenses against dust and airborne allergens during the year's colder months. As it traps particles over time, it grows clogged, becoming less effective the longer it stays in place. If this continues for too long, the furnace will have more difficulty pushing air through, which forces it to work harder. This not only hurts your energy efficiency, but it also shortens the lifespan of your unit. Knowing when to change the filter is critical.

Maintained or Not, Do You Keep the Heat Running Constantly?

The frequency with which you should change out furnace filters will depend on the degree of use. For occasional, sparing use, filters need changing three to four times a year (depending on the size of the filters, of course; smaller versions need more frequent changing). On the other hand, if you're always using the heat, monthly changes might be the best course of action.

Is Your Home a Humans-Only Household?

The frequency of use isn't the only factor that impacts your furnace filter. If you have animals in the house, the fur they shed and the dust particles they can add to the air supply will mean changing your filters more often. If you have multiple animals in the house, changing your filters every one to two months is a good rule of thumb.

Does the Filter Look Like It Needs Maintenance?

Sometimes your eyes can do the best assessment. If the furnace's filter looks too dirty, it likely is! If you see large quantities of dirt and dust, and you don't see how air can pass through, then you're looking at a filter that needs changing as soon as possible. But when in doubt, why leave anything to chance?

Preventative maintenance ensures that your furnace’s filters are always clean, which in turn keeps the system’s efficiency from suffering due to clogged airways.
