An air conditioner is provided with a refrigerant circuit that has a first refrigerant path to which a compressor, a first utilization-side heat exchanger, a first expansion valve, and a heat source-side heat exchanger are connected in order. A control unit controls the compressor and the first expansion valve. When the control unit receives a request for high-temperature air that temporarily increases the temperature of the hot air blown out through the first utilization-side heat exchanger, the control unit changes the control of the first expansion valve so that the temperature of a refrigerant that flows through the first utilization-side heat exchanger increases.
