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