An air-conditioning apparatus comprising: an indoor unit including an air outlet; a refrigerant circuit including a compressor, a first heat exchanger, a pressure-reducing device, and a second heat exchanger included in the indoor unit; a fan included in the indoor unit; a wind guide plate included in the indoor unit, and allowed to be rotated to be in a first state in which the wind guide plate causes air to be blown from the air outlet in a first direction, and to be in a second state in which the wind guide plate causes air to be blown from the air outlet in a direction upwardly inclined to the first direction, the wind guide plate being rotated such that a state of the wind guide plate changes between the first and second states; a first sensor configured to detect a temperature of air in target space for air-conditioning; a second sensor configured to detect a temperature of the second heat exchanger, a controller configured to control the compressor, the fan and the wind guide plate, a fourth sensor configured to detect a temperature of a ceiling surface of the target space; and a fifth sensor configured to detect a temperature of a floor surface of the target space wherein the controller performs a first control, in a case where the compressor is in operation, the fan is in operation, the wind guide plate is in the first state and the second heat exchanger operates as a condenser, when the detected temperature of the air in the target space is higher than a set temperature for the target space and the detected temperature of the second heat exchanger is lower than or equal to a first reference temperature, the first control being a control to keep the compressor and the fan in operation and switch the state of the wind guide plate from the first state to the second state, and wherein the controller performs a second control, when a difference between the detected temperature of the ceiling surface and the detected temperature of the floor surface is greater than or equal to a second difference after the first control is performed, the second control being a control to stop the compressor, keep the fan in operation and also keep the wind guide plate in the second state. an indoor unit including an air outlet; a refrigerant circuit including a compressor, a first heat exchanger, a pressure-reducing device, and a second heat exchanger included in the indoor unit; a fan included in the indoor unit; a wind guide plate included in the indoor unit, and allowed to be rotated to be in a first state in which the wind guide plate causes air to be blown from the air outlet in a first direction, and to be in a second state in which the wind guide plate causes air to be blown from the air outlet in a direction upwardly inclined to the first direction, the wind guide plate being rotated such that a state of the wind guide plate changes between the first and second states; a first sensor configured to detect a temperature of air in target space for air-conditioning; a second sensor configured to detect a temperature of the second heat exchanger, a controller configured to control the compressor, the fan and the wind guide plate, a fourth sensor configured to detect a temperature of a ceiling surface of the target space; and a fifth sensor configured to detect a temperature of a floor surface of the target space wherein the controller performs a first control, in a case where the compressor is in operation, the fan is in operation, the wind guide plate is in the first state and the second heat exchanger operates as a condenser, when the detected temperature of the air in the target space is higher than a set temperature for the target space and the detected temperature of the second heat exchanger is lower than or equal to a first reference temperature, the first control being a control to keep the compressor and the fan in operation and switch the state of the wind guide plate from the first state to the second state, and wherein the controller performs a second control, when a difference between the detected temperature of the ceiling surface and the detected temperature of the floor surface is greater than or equal to a second difference after the first control is performed, the second control being a control to stop the compressor, keep the fan in operation and also keep the wind guide plate in the second state.
