Icing up
An air conditioner that constantly ices up will need to be repaired. It can be due to a lack of refrigerant, bad fan motor, or inefficient compressor. Or it may simply need to be dismantled and professionally cleaned. This involves the use of equipment and tools only your service company will have.

Icing up - only at night
Machine works properly during day, but ices up at night?
Probably because outside temperature falling below 60 degrees Fahrenheit during night. This allows the air conditioner to produce frost on the inside coil. This problem usually occurs in the fall when days are warm, but the nights start to get cold.
If icing occurs when temperature is above 60 degrees Fahrenheit then the air conditioner will need servicing.
