Prepare your semi to be Ready for the Road Ahead™, with the Airsource A/C Expansion Valve that steadily reduces refrigerant fluid pressure. Upon receiving the liquid refrigerant from the drier, this replacement expansion valve reduces the pressure of the fluid to cool it before it is passed to the evaporator. Symptoms of a bad valve or failure include inconsistent air flow, warm AC, or frozen coils.
