Clogged Air Filters Can Lead To Costly HVAC Repair Bills

Posted by Paul Wadsworth on Mon, Jul 04, 2011 @ 09:08 AM

One of the easiest ways to perform good HVAC maintenance is to change the air filters on your heating and cooling equipment. That's also one of the easiest ways to avoid repair bills.

Clean filters facilitate airflow, comfort and safety. Depending upon the type of filter installed, they normally should be checked every month as part of your preventive HVAC maintenance plan, especially during seasons of heavy use. It’s natural for air filters to collect dirt and dust over time. That's what they were designed to do.clogged filters However, if this grime isn’t removed, several negative effects can occur:


  • Airflow will be restricted, meaning your HVAC equipment and ductwork will not handle the amount of air they were designed to handle. The system will strain to reach your desired temperatures, leading to lower efficiency and quicker degradation.
  • Your home will become less comfortable as some rooms are not served with conditioned air, causing hot and cold spots.
  • Utility bills may rise, costing far more than preventive HVAC maintenance.
  • Incoming airflow may bypass the clogged filter, carrying dirt to the cooling coil. This can reduce the coil’s ability to absorb heat.
  • The filter will fail to capture the contaminants it was designed to trap, leading to poor indoor air quality.

Your HVAC system cools air, heats air, filters air, dehumidifies air and circulates air. If the airflow is reduced, your HVAC system can't perform well. Keeping your air filters clean and investing in HVAC maintenance can improve indoor air quality. And by allowing your equipment to function as it was designed, clean filters can reduce your energy use by 5 percent to 15 percent, according to the Department of Energy's Energy Savers program.
