PROBLEM TO BE SOLVED: To provide an air conditioner not causing cost increase, and capable of carrying out wet heating against microorganisms adhered to and growing on an indoor heat exchanger surface during a stopped state of the air conditioner or during heating cycle operation without requiring a humidifying means in an indoor unit casing. SOLUTION: During the stopped state of the air conditioner, or when carrying out the heating cycle operation, when an instruction for inactivation operation is outputted, dehumidification cycle operation is carried out, and it is confirmed by a dew formation sensor whether the indoor heat exchanger surface is covered by dew water. If it is covered by dew water, high temperature heating cycle operation with a higher heat dissipation temperature than the normal heating cycle operation is carried out, and a temperature of an indoor heat exchanger is raised. A surface temperature of the indoor heat exchanger is measured by a temperature sensor, and when the temperature arrives at a protein denaturation temperature of the microorganisms, the indoor heat exchanger is maintained at the temperature or more for a predetermined time.
