International Comfort Products H9MPT050F12B1 Expansion Valve
Almost all AC systems have an expansion valve that permits the refrigerant to spread back into vapor state from a liquid. Your air conditioner would be worthless if the valve was missing.
Major indications your refrigerant expansion valve should need replacing
- Your cooling system takes a long time in its bid to bring down the temp in the house
- Air from the AC is warmer than you are accustomed to coming into the house
