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.

- Visually inspect accessible components for leaks or damage
- Check the operation of the air conditioning compressor and other air conditioning components
- Evacuate refrigerant from the system
- Vacuum test the system
- Recharge the air conditioning system using the appropriate refrigerant to the system capacity according to the vehicle manufacturer's specifications
