The present invention provides a heat pump system for a vehicle capable of improving heating efficiency and a control method thereof. According to an embodiment of the present invention, the heat pump system for a vehicle comprises: a cooling device including a water pump and a radiator connected to a coolant line, and circulating coolant to the coolant line to cool at least one heating body provided on the coolant line; a branch line wherein one end thereof is connected to a valve provided on the coolant line between the radiator and the water pump, and the other end thereof is connected to the coolant line between the radiator and the water pump; and an air conditioner apparatus circulating refrigerant along a refrigerant line to adjust the indoor temperature of a vehicle. A heat exchanger provided in the air conditioner apparatus is connected to the coolant line and evaporates the refrigerant through heat exchange with the coolant supplied through the coolant line in a heating mode of the vehicle. The branch line can be selectively opened and closed by the valve operating in at least one operating mode in accordance with the temperature of the heating body in the heating mode of the vehicle.
