An air-conditioning apparatus capable of suppressing refrigerant flow noise regardless the refrigerant state of an inlet of an expansion mechanism is obtained. In parallel to a flow control valve 4, an opening and closing valve 6 that opens and closes a refrigerant passage and an expansion mechanism 10 having porous bodies capable of passing a refrigerant therethrough are connected in series with each other,. In a heating mode, in the case where a controller 50 stops an operation of one or more of a plurality of indoor units 2 and causes the other indoor unit(s) 2 to operate, the flow control valve 4 of the stopped indoor unit 2 is fully closed and the opening and closing valve 6 of the stopped indoor unit 2 is opened.
