Abstract: An air conditioner and a control method thereof are provided to make pressure difference generated gradually and slowly in the case of mode conversion at an initial operation by controlling operation of a refrigerant conversion valve, thereby preventing generation of abnormal noise. An air conditioner comprises a refrigerant conversion circuit(300) connected between an outdoor unit(100) and indoor units(200a-200c) and having a heating conversion valve(301b) for supplying high pressure refrigerant to the indoor unit for heating operation and a cooling conversion valve(302b) for discharging low pressure refrigerant from the indoor unit per the indoor unit. A controller differs operation time of the heating and cooling conversion valves in response to mode conversion requested by the indoor units which are in a heating or cooling mode, thereby controlling pressure in the indoor units. In the case of heating operation request, the cooling conversion valve is closed and the heating conversion valve is opened after a set time from the closing of the cooling conversion valve. In the case of cooling operation request, the closing and opening of the valves are carried out oppositely.
