The expansion valve injects the refrigerant into the evaporator, changing the refrigerant from a high pressure and high temperature liquid, into a low pressure and low temperature liquid and gas mixture. The expansion valve adjusts the refrigerant quantity according to the temperature of the superheated gas at the evaporator outlet. As a result, conditions are maintained under which the change of the refrigerant state (evaporation) is completed and only gas will flow to the compressor. If the A/C system is not emitting cooled air, or only a little cool air, the expansion valve could be clogged or defective. This type of symptom or fault should always be investigated by an A/C Service Repair professional, because in some conditions it can cause liquid lock in the compressor and end up becoming very costly for the car owner.
