International Comfort Products T8MPV075F14C1 Expansion Valve
A normal AC expansion valve allows the refrigerant to expand into its normal low-pressure gas state from its highly pressured liquid form. The AC in an HVAC system would not produce cooled air if the valve was not working.

- The outdoor AC unit takes a really long time to comfortably cool the indoors
