Provided are an air conditioner capable of completely drying moisture condensed on an indoor heat exchanger while preventing heat from spreading in a room by performing a heating process in which the heat-exchanged air is discharged at low speed through multiple holes during a drying operation, and a method for controlling the same. The air conditioner according to an embodiment comprises: an indoor unit housing; an outlet provided in the indoor unit housing; a heat exchanger provided inside the indoor unit housing and performing heat exchange between a refrigerant and air; a blower fan blowing the air whose heat has been exchanged in the heat exchanger to the outlet; a compressor compressing the refrigerant; and a control unit performing a blowing operation and a heating operation sequentially by controlling the blowing fan and the compressor when a cooling operation is completed. 건조 운전 중 열교환된 공기가 복수의 홀을 통하여 저속 배출되는 난방 운전(heating process)을 수행함으로써, 난방열의 실내 확산을 방지하면서도 실내 열교환기 상에 응축된 수분을 완전히 건조할 수 있는 공기 조화기 및 그 제어 방법을 제공한다. 일 실시예에 따른 공기 조화기는, 실내기 하우징; 상기 실내기 하우징에 마련되는 배출구; 상기 실내기 하우징 내부에 마련되고 냉매와 공기의 열교환이 이루어지는 열교환기; 상기 열교환기에서 열교환된 공기를 상기 배출구로 송풍하는 송풍팬; 상기 냉매를 압축하는 압축기; 및 냉방 운전이 종료되면 상기 송풍팬과 상기 압축기를 제어하여 송풍 운전 및 난방 운전을 순차적으로 수행하는 제어부;를 포함한다.
