There is disclosed an air-conditioner is provided with an indoor unit including a blower fan for a warm or cold wind to the interior of a room, a louver for adjusting the direction of blowing of warm or cold wind from the fan in a range from the ceiling to the floor, a controller for controlling a volume of wind blowing off from the fan, a temperature of a conditioned air, and an angular adjustment of the louver, respectively, and a console panel permitting switching between cooling and heating modes, setting of a temperature, and setting of various modes. A controller provided in this air-conditioner comprises a temperature shifter for setting a raised temperature higher than a set temperature by a predetermined value when a user present in a room and subject to delivery of a conditioned air sets a sleep mode for comfortable sleep during heating, and a louver controller for adjusting an angle of the louver so as to blow warm air having a raised temperature, in the ceiling direction of the room in the sleep mode during heating. With such a configuration, even when a user is going to sleep or is going to wake up, there is no possibility that warm air directly blows him or her. A comfortable air-conditioned environment, particularly when a user is lying close to the floor can be provided.
