How Often Should You Change a Furnace Filter?

Person replacing disposable air filter in residential air furnace.. Your furnace utilizes an air filter to keep your air clean as it enters the system. The filter can catch dust, allergens, and other microbes before they can be heated and spread throughout your property. These air filters come in a variety of filtration levels, so you can easily find one that suits your needs. Typically, it’s recommended that you replace your air filter every three months. However, it can be a good idea to change it more often if you have pets or notice a lot of dust around your home. In this blog, our team at A+ Derr Heating & Coolings discusses the importance of changing your air filters, the signs you need to replace it, and how to swap out an old air filter properly.

The Importance of Changing Your Furnace Filters

While it may be easy to ignore your furnace’s air filter, it’s crucial that you change out the filter from time to time. The air filter works hard to keep your air clean and maintain your furnace. When the air filter is too dirty, your furnace will have to work harder to heat your home, and you could run into a lot of heating issues. In addition, there are several benefits of replacing your air filters every three months. Just a few perks of doing so include:
  • Cleaner air: A clean air filter can do its job better than a dirty one, spreading cleaner air throughout your home.
  • Less HVAC system stress: A dirty air filter makes it harder for your HVAC system to operate.
  • Faster heating and cooling: When your air filter is dirty and clogged, your system can’t pull in air as quickly, making it slower to heat or cool your home.
Clean air filters can make a big difference for your furnace and your entire home.

Signs That You Need To Change Your Filer

When your air filters get dirty or clogged, they will show some obvious signs. While the typical recommendation is to change your air filters every three months, it may be best to do it more often if you have pets or notice a lot of allergens. Some signs that you need to change your air filters include:
  • Dust collecting on your shelves
  • Family members sneezing more often
  • Particulates floating in the air
  • Slow heating or cooling
  • Odd sounds from your HVAC system

How To Change Your Furnace Filter

Changing an HVAC air filter is an easy job that homeowners can do themselves. These filters are typically located close to the furnace or air conditioner, behind a large intake vent. Simply remove the intake vent cover, pull the old air filter out, and install the new one, making sure the arrows point toward the wall. Replacing an air filter takes less than five minutes and can make a big difference in the quality of your air. If you notice that you need to change your filter quite often, seek out air filters with a higher MERV rating, as these will filter out more particulates.
