When I go on holidays, can I switch my air conditioner off at the powerpoint or at the fuse box?

It is OK to turn the power off, especially if you are away for long periods. Most units have a low wattage crankcase heater that keeps the compressor warm. If the compressor is cold, damage will occur at startup. If you turn off your air conditioner it must be turned on at least 12 hrs before use. For more expert advise contact Air Pro Air Conditioning
