International Comfort Products PGMD48H135C Expansion Valve
Pretty much every air conditioning system has an expansion valve that allows the refrigerant to expand into its normal low-pressure gas form from a high pressure liquid state. The air conditioner for your house could not cool the air with no functioning valve.
Key symptoms of a deteriorating main expansion valve
- AC unit takes forever to properly cool as it should
- Air from the AC is well below the temp it should be blowing through the ductwork
