The invention provides a disposal method for greasy blockage of an air conditioner system, a disposal device for greasy blockage of the air conditioner system, and an air conditioner, wherein a refrigerant used by the air conditioner system is a flammable refrigerant. The method comprises the following steps: when detecting that greasy blockage occurs to the air conditioner system in preset work state, recording the current opening of an electronic expansion valve; adjusting the opening of the electronic expansion valve to preset opening from the current opening, wherein the preset opening is greater than the current opening; counting the accumulated operation time of the electronic expansion valve working in the preset opening; and when the accumulated operation time reaches the preset time, detecting whether greasy blockage occurs to the air conditioner system, and performing corresponding disposal according to the detection result. By adopting the technical scheme, the problem of greasy blockage can be timely and effectively solved so that the air conditioner system can recover to normal operation, and therefore, the phenomenon of capability attenuation caused by greasy blockage of the air conditioner can be avoided, and the service life of a compressor and the air conditioner system can be ensured.
