The expansion valve, also known as a metering device, plays a vital role in the air conditioning system. It controls the amount of refrigerant that enters the evaporator, ensuring efficient heat exchange and maintaining the desired cabin temperature. Proper functioning of the expansion valve is essential for the longevity and performance of your AC system. A faulty valve can lead to insufficient cooling, system over-pressurization, or even damage to other components.
