An air conditioner, comprising: an indoor heat exchanger; an indoor fan that circulates air, which has undergone heat exchange in the indoor heat exchanger, indoors; an indoor outlet that is adapted to blow out the air, which has undergone heat exchange in the indoor heat exchanger, indoors; a vertical deflector that is arranged in the indoor outlet and adapted to change an air direction in a vertical direction; an indoor heat-exchanger temperature sensor that measures an indoor heat exchanger temperature (Tr) of the indoor heat exchanger; and a control device that is configured to control at least an air volume of the indoor fan and the air direction of the vertical deflector, wherein the control device includes an air volume controller, which is configured to restrict the air volume of the indoor fan at a start of a heating operation, and an air direction controller, which is configured to control the air direction of the vertical deflector in the vertical direction, characterized in that the air volume controller executes control to increase the air volume of the indoor fan as the indoor heat exchanger temperature (Tr) increases at the start of the heating operation, the air direction controller restricts a position of the vertical deflector so that the vertical deflector is at least faced upward in a blow-out direction adjustment range at the start of the heating operation, and after the indoor heat exchanger temperature (Tr) has increased and the air volume of the indoor fan has been set to maximum, the air volume controller and the air direction controller are configured to cancel the air volume restriction of the indoor fan and the air direction restriction of the vertical deflector when the indoor heat exchanger temperature (Tr) increases further to a preset target temperature (Tt). an indoor heat exchanger; an indoor fan that circulates air, which has undergone heat exchange in the indoor heat exchanger, indoors; an indoor outlet that is adapted to blow out the air, which has undergone heat exchange in the indoor heat exchanger, indoors; a vertical deflector that is arranged in the indoor outlet and adapted to change an air direction in a vertical direction; an indoor heat-exchanger temperature sensor that measures an indoor heat exchanger temperature (Tr) of the indoor heat exchanger; and a control device that is configured to control at least an air volume of the indoor fan and the air direction of the vertical deflector, wherein the control device includes an air volume controller, which is configured to restrict the air volume of the indoor fan at a start of a heating operation, and an air direction controller, which is configured to control the air direction of the vertical deflector in the vertical direction, characterized in that the air volume controller executes control to increase the air volume of the indoor fan as the indoor heat exchanger temperature (Tr) increases at the start of the heating operation, the air direction controller restricts a position of the vertical deflector so that the vertical deflector is at least faced upward in a blow-out direction adjustment range at the start of the heating operation, and after the indoor heat exchanger temperature (Tr) has increased and the air volume of the indoor fan has been set to maximum, the air volume controller and the air direction controller are configured to cancel the air volume restriction of the indoor fan and the air direction restriction of the vertical deflector when the indoor heat exchanger temperature (Tr) increases further to a preset target temperature (Tt).
