The function of an air conditioner is to help remove the heat and humidity from inside the passenger compartment of the vehicle. Powered by a belt, the air conditioning compressor compresses the refrigerant to pressurize it and pump it through the system. The refrigerant is pushed through a valve where pressure and temperature are reduced. The now-cool refrigerant travels through the evaporator in the passenger compartment. As a result, cooled air is blown into your vehicle. This refrigerant returns to the compressor, where the cycle begins once again.
The service is designed as a periodic maintenance service rather than a detailed troubleshooting or repair service. Greg's Auto Village Center technicians begin the service by checking for signs of leaks. We do not recommend servicing systems with detected leaks.*
