Haier HC42D2VAR Expansion Valve
Any home AC unit cannot possibly cool the house if the expansion valve was either damaged or just not working properly. An expansion valve allows the refrigerant to expand back into its natural vaporous form from a high-pressure liquid form.
Major symptoms of a poorly working main expansion valve
- AC takes too long to comfortably cool the home
- Air flow is warmer than the usual air for the AC to cool the house
