Carrier 38YZA036 Expansion Valve
Expansion valves are used in AC systems and allows the refrigerant to expand back to its low-pressure vapor form from its highly pressured liquid form. Air conditioning systems would not produce cooled air if the valve was missing.

- The cooled air is much warmer than the usual air coming from the vents
