The invention provides an air conditioner, a control method of the air conditioner, and a computer readable storage medium. The air conditioner comprises a filtering screen, a sensor and a controller;the filtering screen is arranged at an air return port of an indoor unit; the sensor is configured to obtain current coil pipe temperature of a heat exchanger in the indoor unit, and a current rotating speed of a fan in the indoor unit, and to obtain current air pressure values of the two sides of the heat exchanger, or an air pressure value of one side, close to the indoor, of the filtering screen, and an air pressure value of one side, far away from the filtering screen, of the heat exchanger so as to obtain the current air pressure values; and the controller is configured to detect and confirm that the current coil pipe temperature, the current rotating speed and the current air pressure values meet preset conditions, and judges condensation of the air conditioner. According to the airconditioner, whether the condensation appears can be judged, so that a user can aim at the air conditioner with the condensation for processing in time, and the situation that an air conditioner system is not stable, and a using experience of the user is affected due to the fact that the condensation of the air conditioner brings liquid return is avoided.
