The present invention relates to an air conditioning system for a vehicle and a method for controlling the same and, more specifically, to an air conditioning system for a vehicle and a method for controlling the same in which an opening/closing valve and an expansion valve are installed on a branch line connecting a first air conditioning unit and a second air conditioning unit, the opening/closing valve is always open so as to always supply a refrigerant to the second air conditioning unit during a cooling mode, and the opening/closing valve is always closed so as to always block the refrigerant supply to the second air conditioning unit during a heating mode, such that the refrigerant flows into the branch line of the second air conditioning unit even during a single cooling mode, thereby solving the problem wherein the pressure of a compressor increases, oil is forcibly circulated through a notch of the expansion valve, thereby solving the problem wherein the oil circulation rate decreases, and the refrigerant supply to the second air conditioning unit is blocked during a dual heating mode, thereby solving the problem wherein the heating performance of an electric heating type heater decreases when the second air conditioning unit is operated.
