Changing Your Furnace Filter FAQ

Here at Larry & Sons, we get a lot of calls with questions about furnace filters. Here’s what you need to know to keep your furnace in Hagerstown running well so you can stay warm this winter.

How Often Should I Change My Filter?

We recommend changing your filter once a month when you’re running your furnace every day. If you’re not running yours that often or you want to be sure it needs changing each month, ask one of our professionals. We’ll evaluate your particular furnace and tell you how often we think you should change your filter.

What Type of Filter Should I Use?

Most people find that normal furnace filters work perfectly fine for their needs. If you struggle with allergies at home or you worry about indoor air quality, talk to one of our HVAC professionals about using a furnace filter with a higher MERV rating. These filters trap more particles but they can also cause your furnace to experience more wear and tear. We’ll help you decide if they are right for you.

How Do I Change My Furnace Filter?

Find the access panel in your furnace. Remove any screws holding it in place and flip it up or remove it. Take out the older filter and put the new one back in its place. Make sure you install it with the proper side up so it filters effectively. Replace the access panel and note the date so you know when to change the filter next time. Dispose of the older filter.
