Is a Dirty Air Filter Affecting the Performance of Your HVAC System?

An air filter is an essential part of your home's heating and cooling system. For one, it keeps out dirt and dust from your unit, allowing your system to run more efficiently. Air filters are also responsible for keeping allergens and other nasty particles out of your home's airflow, which helps keep your family healthy.

But just as important as it is to have an air filter, it's equally important to have it regularly checked, cleaned and replaced.

Why air filters need to be checked


If your air filter is doing its job, it's blocking out all kinds of particles from entering your HVAC unit. Over time, those particles will build up and begin to block your system's air flow. When this happens, your heating and cooling system is forced to work harder, which wastes both energy and money. A dirty air filter can also redirect unclean air into other parts of your system, which could result in damaged parts and expensive repairs.

How often to check and replace air filters


There are a number of things that can impact the lifespan and performance of your air filters. These include:
  • The type of air filter you have installed
  • Whether or not you have pets
  • How often your system is running
  • The general quality of air in your home
Regardless of these conditions, it's a good idea to take a look at your air filter every month. You'll want to take it out and check how much dirt has built up on it and whether or not it still looks like it can let air pass through. A good way to do this is to hold it up to a light and see whether or not it shines through.

While checking your filter, keep in mind that you should be either cleaning or replacing your air filter every one to three months. During the summer and winter, you might need to change it even more frequently because your system is working harder and more consistently.

  1. I wish my problems were this simple, I'm having to get my entire HVAC in St Paul MN retrofitted. In the end it's worth it though.
