PROBLEM TO BE SOLVED: To provide an air conditioner suppressing manufacturing costs, and carrying out reheating dehumidifying operation without lowering a blowing temperature. SOLUTION: The air conditioner is provided with a coolant circuit with a compressor 1, a four way selector valve 2, an outdoor heat exchanger 3, a first coolant pressure reducing device 4, a first indoor heat exchanger 5, a second coolant pressure reducing device 6, and a second indoor heat exchanger 7 sequentially connected by a coolant pipe arrangement, an outdoor blower 8, an indoor blower 9, an induction motor for the outdoor blower 8, a room temperature thermistor 11, a first control means for changing an energization ratio to the induction motor to control a rotational frequency of the induction motor, a second control means for changing the magnitude of energization to the induction motor to control the rotational frequency of the induction motor, and a main control means for carrying out control by the first control means on the basis of a detected temperature by the room temperature thermistor 11, and carrying out air capacity control of the outdoor blower 8 by combining control by the second control means when the energization ratio by the first control means is outside of a predetermined range.
