When and How to Change Your Furnace Filter

December 01, 2015

Caring for your furnace can go a long way in the months in between furnace service appointments. One of the simplest, and critical, ways to maintain your furnace is by switching out your furnace filter. Having a clogged air filter could contribute to a host of adverse concerns for your heating and cooling system, its efficiency, and ultimately, how much your energy expenses are each month.

So what goes in to determining when you should change your furnace filter?

  • Type of filter: the two most common filter sizes are 1 inch and 3 inch filters. 1 inch filters usually need to be replaced every month and 3 inch filters need to be swapped out every three months, dependent on the recommendations of the filter maker.
  • Home habits: if you have pets in your home, it could make sense to switch out your filter more often due to pet dander. If you have someone in the house that suffers from allergies or asthma, consider switching out your home’s air filter more often to help potentially decrease their symptoms.

Now you’re possibly wondering how to replace your furnace filter. Obviously this will change depending on what furnace you have, but typically: 

  • Open or remove the air filter panel around the bottom of your furnace to uncover an open compartment.
  • On the top of that open compartment is where you’ll see your furnace filter resting on two metal lips.
  • There will be a bit of space to move your filter back and forth that allows you to remove one end of the filter and take it out of the compartment.
  • When putting in the new filter, look at the perimeter of the filter for an arrow that specifies the air flow direction, to be sure you’re installing the filter in the right direction. In the majority of cases, the arrow should point to the main part (or top) of the furnace.
