When and How to Change Your Furnace Filter

December 01, 2015

Caring for your furnace can help more than you’d think in the period in between furnace service appointments. One of the simplest, and critical, ways to take care of your furnace is by replacing your furnace filter. Having a dirty air filter may contribute to a variety of adverse issues for your heating and cooling system, its efficiency, and ultimately, how much your energy costs are month after month.

So what goes in to deciding when you should switch out your furnace filter?

  • Type of filter: the two most common filter sizes are 1 inch and 3 inch filters. 1 inch filters typically need to be changed every month and 3 inch filters ought to be swapped out every three months, based on the recommendations of the filter company.
  • Home habits: if you have pets in your home, it might make sense to replace your filter more often as a result of pet dander. If a family member suffers from allergies or asthma, think about changing your home’s air filter more often to help potentially decrease their symptoms.

Now you’re possibly wondering how to replace your furnace filter. Inevitably this will vary depending on what furnace you have, but usually: 

  • Open or remove the air filter panel around the bottom of your furnace to expose an open compartment.
  • On the top of that open compartment is where you will find your furnace filter resting on two metal supports.
  • There will be a small amount 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 adding the new filter, inspect the perimeter of the filter for an arrow that shows you the air flow direction, to ensure you’re installing the filter in the correct direction. In the majority of cases, the arrow should point towards the main part (or top) of the furnace.
