You probably would be surprised to find out all the negative impacts a dirty HVAC air filter can have on your home’s comfort, energy efficiency and air quality. While simple to replace, the air filter performs a vital function in your forced-air central air conditioning or heating system. Learn why a dirty or clogged air filter should be avoided.

Air Filter Benefits

Indoor air quality. The air filter, usually positioned in the ductwork near where it connects with your central cooling or heating equipment, removes particulates from the air before it’s drawn into the equipment to be heated or cooled. These airborne particulates can include common household dust, mold spores, cloth fibers, pet dander, pollen, bacteria and more. Some of these contaminants can directly threaten your health and that of other family members, especially those with allergies or respiratory conditions. If the filter gets clogged, some of those contaminants are liable to get blown past the filter and into conditioned air that re-circulates through your home.

Energy Efficiency. If dust and debris aren’t stopped by an efficient air filter, they are likely to settle on components of your cooling or heating system. A dirty blower motor will experience more friction, and as a result waste energy doing its job. The increased workload will lead to early repairs and a shorter life span. With an A/C or heat pump, a dirty evaporator coil will struggle to complete the heat-exchange process that’s vital to these systems’ operation.

Comfort. When dirty air is circulating in a home, it can erode comfort, as can a heating or cooling system that’s struggling to push conditioned air through a dirty air filter. Some rooms will not receive the cooling or heating that you expect.

Choose an air filter that’s rated high enough to remove most airborne particulates, but not so efficient that it will restrict system airflow. Check the filter monthly and change it when it looks dirty.
