What happens when an evaporator coil gets dirty?
An extremely dirty evaporator coil can cause your AC to breakdown completely. This happens when condensation forms on the dirt and then freezes during the AC’s operation. The buildup of frost stops the heat transfer with the air in your home, which causes the air conditioner to stop cooling air at all.
How often should evaporator coils be cleaned?
Evaporator coils should be cleaned at least once a year. By keeping them clean, you will also minimize energy usage and reduce utility costs. It is estimated that dirty evaporator and condenser coils can increase the energy usage of your AC system by over 30 percent!
What causes the evaporator coil to freeze?
One of the most common causes of a frozen evaporator coil is lack of system airflow. … If there isn’t enough air blowing over your evaporator coil, the coil won’t have enough heat to absorb. This will cause the condensation on the coil to freeze over.

Do evaporator coils have SEER ratings?
The federal government requires that you have an air conditioner unit with a seasonal energy efficiency ratio (SEER) rating of at least 14. A SEER is an energy efficient ratio for all HVAC units. … This is because you can’t match an evaporator coil with a SEER 14 rating with a unit that has a rating of 13 or lower.
