The invention relates to the technical field of air conditioner control, and discloses a method for controlling an air conditioner, which comprises the following steps: determining the stress cycle times of piping and the average stress impact times of each shutdown of the piping; calculating shutdown limit times according to the stress cycle times and the average stress impact times; determining a service life prolonging strategy of the air conditioner according to the shutdown times and the shutdown limit times of the air conditioner outdoor unit; and controlling the air conditioner to execute the life prolonging strategy. According to the scheme, the fatigue condition of the air conditioner pipeline can be reasonably predicted in combination with the shutdown times of the air conditioner outdoor unit and the calculated shutdown limit times, so that a proper service life prolonging strategy is selected according to different fatigue conditions of the air conditioner pipeline, and the service life of the air
