GREE TERRA12HP230V1A Expansion Valve
Any home AC unit would produce no cooled air if it was deprived of a functioning expansion valve. A normal AC expansion valve makes it easier for the refrigerant to expand back into its natural gas state from a liquid.
Indications your refrigerant expansion valve needs to be replaced
- Cooled air is much warmer than it really should be coming from the AC
- Your AC unit takes too long in its effort to cool all the rooms in your house
