This air-conditioning system has: an indoor unit having a fan; an outdoor unit connected to the indoor unit via a refrigerant tube, the outdoor unit transmitting and receiving communication signals to and from the indoor unit; and an emergency power source connected to the indoor unit, the emergency power source supplying power to the indoor unit during a power failure. The indoor unit has a controller for controlling the action of the fan in accordance with the state of communication with the outdoor unit. The control unit includes: an energization-time error determination unit for determining, when a communication error occurs in communication with the outdoor unit, whether or not the communication error is an energization-time error inherent in the energization time at which power is supplied to the outdoor unit from a commercial power source; a connection establishment error determination unit for determining, when the energization-time error determination unit determines that the communication error is not an energization-time error, whether or not the communication error is a connection establishment error produced when connection with the outdoor unit is established, and for sensing the power failure of the outdoor unit; and a fan control unit for driving the fan using power supplied from the emergency power source when the connection establishment error determination unit determines that the communication error is a connection establishment error.
