How to Change A Furnace Filter

As a responsible homeowner with a furnace, you probably know how important it is to change your filter regularly. After all, you want your furnace to last and you want your HVAC system to last a long time.

If you’ve never changed a furnace filter before, then you feel intimidated by the task, or embarrassed for asking “How do I change a furnace filter?” However, it doesn’t have to be that way. 

We’ve created this guide to answer related questions and teach you how to change a furnace filter. And if you want one of our experts on HVAC maintenance in Northfield to demonstrate the process for you, give us a call and we’ll send an HVAC expert to arrive at your door soon. 

Most furnace filters should be changed every 1-3 months. The exact length of time between changes depends on a lot of factors, like how often you are using your comfort systems, whether you have pets or nearby construction that might produce substances that clog your filters, whether anyone in your home suffers from allergies or asthma and more. 

Our experts on HVAC maintenance in Northfield can help you decide how often you need to change your air filters. Contact us today and we’ll send a heating service expert out to examine your unit and your home, then let you know how frequently they need to be changed.

Changing a Furnace Filter

The process of changing a furnace filter will be slightly different for each furnace involved. If you have the manual for your unit or you can access it online, that is the easiest way to determine exactly how to change your furnace filter. 

However, the process is similar enough between units that we can give you some pointers. 

First, turn off the furnace and find out where the current filter is located, and access it. Note the filter size so you can go to your local hardware store and buy a new one. You may also be able to find a subscription service that will send you a new filter at your desired interval so you’ll always have a fresh one when you need it. 

Next, remove the existing filter. Note its exact position in your furnace and put the new one in identically. It’s important to get the proper side facing the proper direction.

Finally, close your furnace and turn it back on. As long as you don’t have indoor air quality problems, you most likely got the new filter installed correctly.
