Your air conditioner’s indoor evaporator coil works as a heat exchanger. Refrigerant inside the coil evaporates as heat is absorbed from the air passing through the system. These coils have fins that help the heat exchange process. However, air conditioner fins can sometimes get bent during maintenance, blocking airflow.
The other half of split system air conditioners, the condenser, is located outside and has fins as well. The purpose of the condenser coil is to release heat from the refrigerant. Likewise, the condenser coil fins play an important part in this process. These fins can bend from pressure washing, hail, tree debris, careless weed eating procedures, twigs and rocks.
It’s best to call an HVAC pro when your air conditioner fins are bent. Ask your service pro to check the fins when he or she is performing regular maintenance.
