International Comfort Products TCH218AKA1 Expansion Valve
Pretty much every air conditioning system has an expansion valve that makes it easier for the refrigerant to expand into its normal low-pressure gas state from a high-pressure liquid form. A split-system AC unit could not run if the expansion valve was totally worn out.
Simple signals the expansion valve will have to be replaced
- The air is definitely not as cold as it should be blowing through the ductwork
- The cooling system takes a really long time to comfortably cool as it should
