An Expansion device regulates the flow of gas inside the A/C system. You have the ability to control the cooling level of your car A/C system. If you want the A/C system to get colder, the expansion valve expands and releases refrigerant through the system. If you decrease the cooling level, the expansion valve shrinks and slows down the release of refrigerant.
