How Dirty Evaporator Coils Lead to Air Conditioning Repair Work

Your air conditioner is a finely balanced system composed of numerous complex components that work together to help your home reach a desired temperature. When this balance is thrown off because of a dirty condenser or evaporator coil, your AC system may fail to perform effectively. If ignored, the problem will worsen overtime to the point where not only will your HVAC system be unable to cool your home, but its components may become damaged and require professional repair. The problems caused by dirty evaporator coils are explained in more detail below.

The Evaporator Coil
The evaporator coil transfers heat from the air inside your home to the refrigerant of your AC system. Dirt has a similar effect on this coil as it does to the condenser coil. It interferes with efficient heat transfer into the coil because dirt is an insulator and it blocks airflow across the coil. Although your home is a cleaner environment than that of the condenser (which is outdoors), the air still has dust particles that eventually clog the air filter. Some of this dirty air will bypass the clogged filter, blow across the evaporator coil, and stick to its damp surface.

Icing is another problem that occurs because of reduced air flow across the evaporator coil. When warm air from your home stops flowing over the coil, it cools down and freezes the condensation on its surface. Eventually, the coil turns into a block of ice. The refrigerant gets colder and damages the compressor.

As you can see, the evaporator coils must be periodically inspected and cleaned. If your AC system hasn't seen any maintenance work in a while, contact your local Coral Springs FL air conditioning repair professional.
