How Often Should You Change Your Furnace Filter?

With the $22 billion spent by Americans on heating and cooling costs every year, a lot of that spending is due to inefficiency.

If you help your system to run more efficiently, you could be saving money on energy costs and helping to reduce waste. If you want to know how often should you change your furnace filter, you need to get to know a little more about your system.

Here are the top 7 reasons to help you decide when to change your furnace filter.

If you’ve recently moved into a new home or purchased some property, you’re going to be inheriting everything that the former residents left behind. There’s sure to be some things left in the medicine cabinet, things shoved under the floorboards by kids, and definitely loads of dirt and grime. Even if the former tenants cleaned the place out, there are always corners that grime and dust can hide in.

Before you start inhabiting the place, you should check out the furnace filter. It’s likely there is going to be a thick dense carpet of dust and hair that’s been collected by it. Put in a new filter immediately and dispose of the old one.

One of the main centers for dust and grime to settle is on the inside of the HVAC system. Before you move in, you should open all the windows and throw on the system. If it sounds good and starts up smoothly, let it run for awhile with the windows open. You’re likely going to have a lot of stale air and even some mold to let out of the system.

After you’ve let it run for an hour or two, you can go back into the home. You should do a good dusting, vacuuming, and cleaning up before you move anything in. Call an HVAC professional and see if they can clean out the system if any smells or staleness persists.

2. When You’re Sensing Trouble

One of your best tools in dealing with your HVAC system is by listening to it. If you hear your system struggling, it could be struggling to pull in air or push it out. One of the quickest ways to deal with your system is to change the filter.

Provide any service records that you have on hand. If they can see that a certain part hasn’t been changed in a while, they might be able to fix the system quickly. If the sound persists after they leave, ask them to describe it better to you. Call another service professional for a second opinion if you don’t trust what they’ve done.
