The air conditioner control method comprises the steps that the exhaust temperature of a compressor is detected in the starting process; judging whether holding control, frequency reduction control or forced shutdown protection conditions are met or not; if yes, corresponding holding, frequency reduction or forced shutdown protection is executed; recording frequency reduction control and protection control times; if one of the exhaust protection conditions meets the exhaust protection condition, exhaust protection control is executed; whether the exhaust temperature of the compressor meets the frequency reduction control condition again or not is judged, if yes, the exhaust temperature correction value is called to correct the boundary threshold of the control condition till the operation frequency of the compressor is kept within the set interval within the first set period, and the sum of the exhaust temperature correction value is calculated; and the sum of the exhaust temperature correction values is comp
