Mitsubishi MSZ-A17NA Expansion Valve
An expansion valve facilitates in helping the refrigerant to expand back into its natural gas state from a high-pressure liquid form. A split-system AC unit would not produce cooled air without a working expansion valve.
Key symptoms to watch for in a bad AC expansion valve
- Your cooling system takes a really long time to appropriately keep the house cool
- AC air production is warmer than the usual air blowing from the vents
