An automobile air conditioner includes a duct interconnecting a blower unit and a temperature control/air distributing unit having a pair of cooling and heating heat exchangers, the duct having a cross-sectional area gradually increasing toward the temperature control/air distributing unit. The air conditioner preferably has a hot/refrigeration compartment juxtaposed with the duct. In a preferred embodiment, the air conditioner includes a hot air control mode door for controlling a stream of hot air flowing from the heating heat exchanger toward an upper air outlet and a lower air outlet.

A casing accommodating the heater core comprises a main body formed by first and second casing elements joined together at their peripheral edges, and a third casing element detachably joined to the main body and formed with hot air outlets. Part of the peripheral edges of the first and second casing elements cooperate to define an opening at which the third casing element is joined to the main body. The opening is exposed to the outside when the third casing element is detached from the main body, and through which the heater core can be removed from and fitted into the casing with ease.
