Provided is an air conditioner comprising a heat exchanger unit in which the installation position of an intake temperature sensor can be changed, the air conditioner making it possible to determine whether the intake temperature sensor has been installed in the correct position. During an air-cooling operation, the heat exchange temperature Th is lower than the intake temperature Ti, and during an air-warming operation, the heat exchange temperature Th is higher than the intake temperature Ti. However, if an intake temperature sensor 62 is erroneously positioned on the downstream side with respect to the airflow in an indoor heat exchanger 51, the intake temperature Ti detected by the intake temperature sensor 62 would be the temperature of indoor air after having exchanged heat with a refrigerant in the indoor heat exchanger 51, and the heat exchange temperature Th and the intake temperature Ti would be near each other regardless of whether the operation is air-cooling operation or air-warming operation. Therefore, if the temperature difference ΔT between the heat exchange temperature Th and the intake temperature Ti is a value greater than –5°C and less than +5°C, it can be determined that the heat exchange temperature Th and the intake temperature Ti are near each other, i.e., the intake temperature sensor 62 is erroneously positioned.
