The invention relates to an overhauling method for air conditioning units of a railway vehicle. The two air conditioning units arranged in a carriage and used for transmitting operation data outwards and an overhauling device used for receiving and displaying the operation data are included. The overhauling device is connected with the two air conditioning units through communication interfaces, receives the operation data, analyzes the received operation data and then displays the analyzed operation data, and whether one of the air conditioning units breaks down or not is judged by comparing the operation data of the two air conditioning units. According to the overhauling method, the data of the two air conditioning units are compared, so that whether one air conditioning unit of the two air conditioning units in the same carriage breaks down or not is easily judged, and the problem that the performances of the two air conditioning units interfere and cover each other, and faults of one air conditioning unit are difficult to find is solved. The state of the operation data of the air conditioning units is displayed through the overhauling device, the faults of air conditioners can be clearly found, and the overhauling time is greatly shortened to be within 10 minutes.
