Your HVAC system works by circulating conditioned air around your home.

❌ No.1 – Higher Energy Bills

So the performance of your blower fan can significantly impact your home’s energy consumption. These inefficiencies caused by a clogged air filter increase exponentially until you replace a bad air filter with a new one.

If your evaporator coil does not have adequate airflow, it cannot remove heat as designed. This will cause the temperature on the coil to drop below freezing.

❌ No. 2 – Frozen Evaporator Coils

If your air filter becomes clogged with dirt, dust, debris, pet dander etc., it can be increasingly difficult for your fan to achieve the desired temperature during the summer cooling season.

❌ No. 3 – Reduced Airflow

A dirty air filter can significantly contribute to contaminated air in your home. This is particularly dangerous for people with chronic allergies, asthma or other respiratory conditions.

❌ No. 4 – Lower Indoor Air Quality

All of the problems listed, if not treated, can lead to the most expensive pain of them all, the total failure of your heating and cooling system.
