Carrier 48GX060090300 Expansion Valve
Your home AC system contains an expansion valve that allows the coolant to expand back to its low-pressure vapor form from its highly pressured liquid form. Your main AC unit cannot possibly cool the house if the valve was missing.

- The outdoor AC unit takes a long time in its bid to cool as it should
