Carrier 39LB Expansion Valve
An expansion valve allows the refrigerant to expand back into gas state from a high-pressure liquid form. Any home AC unit can not deliver properly cooled air if the valve was missing.
Some clues of a dying AC expansion valve
- Your AC takes a long time to actually cool the indoors
- The air conditioned air is not cold enough as it really should be blowing through the ductwork
