Abstract

The present invention provides an air conditioner and a control method thereof that can efficiently reduce the degree of contamination of indoor heat exchangers. [Solution] An air conditioner control method according to one embodiment is a control method for an air conditioner equipped with an indoor heat exchanger that exchanges heat between a refrigerant and indoor air, and includes the steps of: accumulating the pollution index of the indoor heat exchanger; and comparing the accumulated pollution index with a first standard pollution index, wherein if the accumulated pollution index is equal to or greater than the first standard pollution index, a heat exchanger cleaning process is performed.
