An air conditioner that includes a refrigerant circuit connecting a plurality of indoor heat exchangers in parallel and is able to complete collection of refrigerant to the side of an outdoor heat exchanger in a shorter time when the refrigerant has leaked at any indoor heat exchanger is provided. Thus, in the air conditioner according to the present invention, when refrigerant leak is detected by a refrigerant leak sensor provided in an indoor unit and refrigerant leak is not detected by a refrigerant leak sensor provided in an indoor unit, an indoor LEV and a cutoff valve are closed to isolate an indoor heat exchanger of the indoor unit from the refrigerant circuit in a refrigerant pump-down operation. When refrigerant leak is detected by the refrigerant leak sensor and refrigerant leak is not detected by the refrigerant leak sensor, an indoor LEV and a cutoff valve are closed.
