GE AZ75H18DACM1 Expansion Valve
Almost all AC systems have an expansion valve that allows the coolant to expand back into its natural gas state from its highly pressured liquid form. The AC for your home would most likely give you heated air if it were lacking a functioning expansion valve.
Indications your main expansion valve is in dire need of a replacement
- The cooling system takes too long in its bid to cool the home
- The air conditioned air is well below the temp it used to be comes through the ducts
