Carrier 58CTX07010008 Expansion Valve
An expansion valve permits the refrigerant to expand back into gas state from its highly pressured liquid form. Any home AC unit would not yield any cooled air if the expansion valve was either damaged or just not working properly.

- AC takes too long in a bid to cool the home
