International Comfort Products N9MP1100J20C1 Expansion Valve
Your home AC system contains an expansion valve that permits the refrigerant to expand into its normal low-pressure gas state from a high pressure liquid state. The AC in a split system can not run without a working expansion valve.
Hints of a barely functioning refrigerant expansion valve

- AC takes a really long time in its bid to cool all the rooms in your house
