International Comfort Products C9MPT075F14B1 Expansion Valve
Almost all AC systems have an expansion valve that allows the refrigerant to expand back to its low-pressure vapor form from a liquid. Your AC would probably be the worst AC in the world if the valve was not functioning.
Major symptoms of a poorly working expansion valve
- AC takes a really long time to comfortably cool
- The air is not cold enough as it should be in order to feel comfortable
