A method for cleaning an air conditioner includes: in response to a cleaning instruction, controlling frosting on the surface of a target heat exchanger; after a frosting completion condition is met, controlling defrosting of the frost on the target heat exchanger; and after a defrosting completion condition is met, reducing the surface temperature of the target heat exchanger to a sterilization temperature, and carrying out quick cooling sterilization, wherein the temperature difference between the sterilization temperature and the defrosting temperature during defrosting meets a set temperature change sterilization condition. By a frosting-defrosting process, dirt such as dust on the heat exchanger may be effectively stripped and deep bacteria may be exposed, and then the quick cooling sterilization process may kill the bacteria by utilizing the sharp temperature change during switching from the defrosting process to the quick cooling process. Also disclosed is the air conditioner.
