Mitsubishi MUZ-GE18NA Expansion Valve
Your home AC system contains an expansion valve that allows the refrigerant to expand into its normal low-pressure vaporous form from a high pressure liquid state. The AC for your home could not work if the expansion valve was somehow damaged.
Major signs your refrigerant expansion valve is going out
- Your AC takes way too long to cool
- The cooled air is not as cold as it should be blowing through the ductwork
