Carrier FY4ANF048000 Expansion Valve
Your home AC system contains an expansion valve that allows the refrigerant to expand back into its natural gas state from a high-pressure liquid form. An AC would be broken if the valve was not working.
How do you know if your Carrier expansion valve is failing?
- Your AC takes too long trying to cool the indoors
- Air flow is not as cold as it ought to be coming into the home
