An air conditioner comprises a control portion and a refrigeration system wherein a compressor, a condenser, an expansion device and an evaporator are connected in a refrigerant flow relationship. The control portion compares the temperature measured by a room temperature sensor with the temperature set by a temperature setting switch. For heating, the compressor is stopped when the room temperature rises higher than the set temperature, and for cooling, the compressor is stopped when the room temperature falls lower than the set temperature. A special switch is installed in the control portion, and when this switch is operated, responsively the range of the temperature set by the temperature setting switch is changed. More specifically, when the switch is operated at heating the control portion lowers the upper limit of the temperature set by the temperature setting switch and at cooling, the lower limit of the temperature is heightened by the control portion. Thereby the capacity of heating or cooling of the air conditioner is reduced, therefore an over cooling at cooling and an over heating at heating can be prevented.
