Goodman GSX130241 Expansion Valve
Expansion valves are used in AC systems and allows the coolant to expand back into gas state from a high pressure liquid state. The AC in your house would produce no cooled air if the expansion valve was totally worn out.
Warnings to watch for in a failing main expansion valve
- The cool flow of air is warmer than you are accustomed to blowing from the vents
- The cooling system takes a long time to properly cool
