An object is to provide an air conditioner capable of providing superior reach of warm air upon starting up in a heating mode so that the user can immediately have a feeling of warmth. An air conditioner (1) includes vertically separated upper and lower outlets (41, 45) for blowing conditioned air supplied through an indoor heat exchanger (17) by a turbofan (19) into the interior of a room; and a controller (23) for controlling operation. The controller (23) has a heating startup mode (79) that is entered upon starting up in a heating mode and in which the conditioned air is blown only from the lower outlet (45) for a predetermined period of time if the air volume is set to an automatic mode and the air direction is set to a mode in which the air is blown from both the upper outlet (41) and the lower outlet (45).
