Abstract
In order to derive, from operation data obtained from an air conditioner, the correct cause of malfunction of the air conditioner and the suitable repair information, a diagnostic system is connected to an outdoor unit and the indoor units of the air conditioner, which is provided with communication units. A mobile communication terminal requests that the communication units of the air conditioner transmit the operation data and the model data to the mobile communication terminal, which then communicates with a maintenance server system storing a diagnostic program corresponding to each model of air conditioner. Then, either the maintenance server system or the mobile communication terminal uses the diagnostic program corresponding to the model data to make a diagnosis of the air conditioner on the basis of the received model data and operation data. The diagnostic result is displayed on a display unit of the mobile communication terminal.
