Maintaining your furnace can go a long way in the months in between furnace service appointments. One of the easiest, and crucial, ways to take care of your furnace is in switching out your furnace filter. Having a clogged air filter could contribute to a variety of unfavorable concerns for your heating and cooling system, its efficiency, and ultimately, how much your energy expenses 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 usually need to be switched out every month and 3 inch filters ought to be replaced every three months, dependent on the recommendations of the filter company.
- Home habits: if you have pets in your home, it could make sense to change your filter more often because of pet dander. If a family member suffers from allergies or asthma, contemplate replacing your home’s air filter more regularly to help with their symptoms.

- Open or take off 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 remove it from the compartment.
- When putting in the new filter, check the perimeter of the filter for an arrow that indicates the air flow direction, to make sure you’re installing the filter in the correct direction. In the majority of cases, the arrow should point to the main part (or top) of the furnace.
