LG ARNU363TNC2 Expansion Valve
Any home AC unit would not yield any cooled air if the expansion valve was broken. Your home AC system contains an expansion valve that allows the refrigerant to expand back into vapor state from its highly pressured liquid form.
Main clues the AC expansion valve needs replacing
- The outdoor AC unit takes way too long to actually keep the temperature down
- AC air production is not as cool as it ought to be coming into the home
