The invention discloses an air conditioner hanging machine which comprises a face frame, an upper chassis, a lower chassis and side plates. The face frame is provided with a front side. The upper chassis comprises a top wall and a rear side wall which are integrally formed, and an air-inlet grille is integrally formed on the top wall. The side, away from the rear side wall, of the air-inlet grille is detachably connected with the face frame. The connecting position of the air-inlet grille and the face frame is located on the front side. The lower chassis is detachably connected with the upper chassis. According to the technical scheme, the connecting position of the air-inlet grille and the face frame is located on the front side, so that the connection position can be directly visualized by a person, and the person can conveniently mount or dismount the face frame and the upper chassis; and furthermore, the arranged connecting position of the face frame and the air-inlet grille is not limited by the distance between the air conditioner hanging machine and the top of a wall, so that the mounting flexibility of the air conditioner hanging machine is further improved.
