Carrier 48HJE014 Expansion Valve
An air conditioner would not generate and cold air if the valve was missing. Every air conditioning system contains an expansion valve that allows the coolant to expand back into its natural gas state from its highly pressured liquid form.
What red flags are there that my AC expansion valve is almost dead?
- Air from the AC is warmer than it used to be exiting the air handler
- Your cooling system takes a long time to comfortably cool all the rooms in your house
