How a Clogged Air Filter Damages Your AC System in Oak Ridge, TN

Your air conditioner’s filter removes debris from the air that can collect in your system. Without changing your filter regularly, particles build up and impact system performance. Find out how a clogged air filter interferes with the operation of your AC system in Oak Ridge, TN.

AC System Will Have to Work Harder and Longer

Your air conditioner works by absorbing hot air in your home and cooling it. The system then returns the chilled air into your house for circulation.

When you have a clogged air filter, your AC system will have to work longer trying to push the cooled air back into your living space. The longer your system works, the more likely it is to break down. These breakdowns may result in expensive air conditioning repairs.

Increased Energy Bills

When your filter is dirty, the AC system’s blower fan will have difficulty recirculating conditioned air into your home. Therefore, the fan will have to run longer trying to achieve its objective. The longer it runs, the more your energy bill will rise.

Scheduling regular air conditioner maintenance ensures dirt doesn’t accumulate on your filters. According to the US Department of Energy, changing your AC filter regularly reduces your energy bills by up to 15%.

Evaporator Coils Will Freeze

The cooling process involves the continuous airflow into and out of the AC system. When debris blocks your filters, there’s an interruption in the normal circulation of air.

The cooled air builds up on the evaporator coil, causing them to freeze. Consequently, your unit cannot continue to cool your home.


Due to reduced airflow through your unit, your AC system has to work harder. Consequently, your AC components, such as the compressor and blower, will experience excessive strain.

Too much stress causes your system to overheat and start short-cycling. In addition, your AC system may start breaking down frequently.
