Goodman GKS90453BXAB Expansion Valve
Expansion valves are used in AC systems and makes it easier for the refrigerant to expand back into gas state from a high-pressure liquid form. Your main AC unit could not run if the valve was not working.
Important hints the expansion valve is failing
- The air conditioned flow is not cold enough as you are accustomed to being blown into the house
- Your cooling system takes a really long time to actually cool your home
