Carrier 38HDF018 Expansion Valve
Almost all AC systems have an expansion valve that allows the refrigerant to expand into its normal low-pressure vaporous form from its highly pressured liquid form. A split-system AC unit would not produce cooled air if the expansion valve was totally worn out.
Elements of a laboring refrigerant expansion valve

- The cool flow of air is definitely not as cold as than the usual air so as to feel comfortable in the house
