A ceiling embedded type air conditioner is embedded in a ceiling surface and includes an outlet that blows out air conditioned air toward an indoor space, and a louver capable of changing a blow-out vertical direction of the air conditioned air at the outlet. If a state in which a wind direction position of the louver is set so that it is oriented to a wind direction position continues for a first prescribed time or longer, then the louver is temporarily changed to a wind direction position more downward than the wind direction position, and once again changed to the wind direction position.
