Edgestar AP14001HS Expansion Valve
Almost all AC systems have an expansion valve that permits the refrigerant to expand into its regular vaporous form from its highly pressured liquid form. An air conditioner would be worthless if the valve was not working.
Major warnings of a failing expansion valve
- AC takes way too long in attempting to keep the temperature down
- Air flow is definitely not as cold as than the usual air coming out of the vents
