Taking care of your furnace can help quite a bit in the period in between furnace service appointments. One of the simplest, and critical, ways to care for your furnace is by changing your furnace filter. Having a clogged air filter may contribute to a variety of negative concerns for your heating and cooling system, its efficiency, and ultimately, how much your energy costs are every month.
So what goes in to consideration 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 should be changed every three months, dependent on the recommendations of the filter maker.
- Home habits: if you have pets in your home, it might make sense to change your filter more often due to pet dander. If you have someone in the house that deals with allergies or asthma, think about switching out your home’s air filter more frequently to help potentially decrease their symptoms.
Now you’re possibly wondering how to replace your furnace filter. More than likely, this will vary depending on what furnace you have, but usually:
At Finch Air Conditioning & Heating Inc, we’ll change out standard one-inch furnace filters as part of our regular furnace service Precision Tune-up or PLUS Maintenance Agreement service. Give us a call today at or set up an appointment with us online.
- Open or pull off the air filter panel close to 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 pull down one end of the filter and take it out of the compartment.
- When adding the new filter, look at the perimeter of the filter for an arrow that specifies the air flow direction, to make sure you’re installing the filter in the proper direction. In nearly all cases, the arrow should point to the main part (or top) of the furnace.
