This also could be caused because of a restriction is your refrigerant line, a bad thermal expansion valve, and a bad blower motor. When you See your AC unit is iced over, please do the following before calling an ac company out and avoid a service call fee. First, turn off the AC mode to the off position and turn your fan to the on position. This will circulate air across the ice and help the ice to dethaw faster without your AC running. Leave the unit in this state for 4-6 hours to ensure there is no more ice in the system. Once you verify the ice is gone, replace your air filters and turn the unit on.
