A dirty filter in your HVAC system will raise your energy bills. A dirty filter restricts the air flow into your HVAC systems air handler, causing it to work harder to cool or heat your home.

A dirty clogged filter can restrict HVAC airflow and potentially cause problems with the system. They also cease to filter allergens and other particulates out of your air.
