Why is my air conditioning unit getting covered in ice?

Answer by  kipcat (1964)

If you are referring to the part of the air conditioner in the house, there are a couple problems that lead to this condition. A completely clogged air filter will cause the coil to freeze up or the unit can be low on charge, lastly the unit can be so oversized that in certain conditions it will freeze.

There are many different reasons why it might ice. One is that the fan is not moving or is not moving fast enough resulting in the cold air remaining stagnant.

The main reason for ice buildup on air conditioning systems is humidity. Humidity turns into condensation on the unit then becomes frozen when the unit cools and freezes the condensation.
