What causes an AC unit to freeze up?
When there isn't an adequate amount of refrigerant in an AC system, the pressure will drop inside the unit. This will then cause temperatures to fall in the evaporator coils—which can dip below freezing. When this happens, nearby water vapor can grab onto these coils and freeze.
