A method of controlling an air conditioning system for a vehicle is provided. The method includes detecting a cooling mode while the vehicle is being driven and comparing a vent discharge temperature of air with a cooling target temperature set by a user. When the vent discharge temperature is greater than the cooling target temperature the compressor RPM is determined and air is introduced into the vehicle without passing through the interior heat exchanger and the electric heater. When the vent discharge temperature is less than the cooling target temperature, the compressor RPM is determined and a door in the system is opened to guide the air through the interior heat exchanger to heat the air is heated and then the vent discharge temperature is compared with the cooling target temperature again, and the electric heater is operated.
