An air conditioning unit is made up of multiple components, with the evaporator responsible for turning liquid refrigerant into cool air, which is then pumped through small vents into your vehicle cabin. The expansion valve is responsible for lowering the pressure and controlling the flow of the refrigerant before it turns into vapour in the evaporator. An expansion valve is one of the most important elements to a car’s air conditioning system and can cause serious damage to your AC unit if left alone while faulty.
