The invention relates to the technical field of air conditioning, particularly provides an air conditioner and a control method thereof, and aims to solve the problem that a compressor cannot enable the air conditioner to operate normally when the compressor is started after a refrigerant is recycled to an outdoor heat exchanger by the existing air conditioner to a certain extent. The air conditioner comprises a first branch communicated with a refrigerant container and an inlet of a gas-liquid separator and a first on-off valve arranged on the first branch, and the control method of the air conditioner comprises the steps that under the condition that refrigerants are recycled into an outdoor heat exchanger and the refrigerant container, the first on-off valve is selectively and intermittently in an open state; and the control valve is in a state of allowing the refrigerant to flow through. In this way, the refrigerant in the outdoor heat exchanger can be discharged, the outdoor heat exchanger has some space
