<p>PURPOSE: An air conditioner is provided to predict whether a line connected to a first communication unit is a communication or not and whether the line is a power line or not based on detected voltage. CONSTITUTION: One of an indoor unit(100) and an outdoor unit(200) in an air conditioner comprises switching units(160,250), voltage distributing units(170,260), communication units(150,240), and control units(130,220). The switching unit receives or transfers a communication signal each other by being turned off in a standby mode or by being turned on in release of the standby mode. The communication unit generates a releasing signal when voltage over predetermined voltage is putted in the voltage distributing unit. The control unit turns off the switching unit by determining a start time of the standby mode and controls the switching unit when the releasing signal is received through the communication unit during the standby mode.
