International Comfort Products PGMD24G0408 Expansion Valve
Almost all AC systems have an expansion valve that allows the coolant to spread back into gas form from a high-pressure liquid form. Air conditioning units would be impossible to cool the home if it were lacking a functioning expansion valve.
Symptoms your main expansion valve should need replacing
- Your AC takes forever to comfortably cool
- The air conditioned air is not as cold as it ought to be for the AC to cool the house
