Payne PA1ZNA024000ABAA Expansion Valve
A split-system AC unit can not supply your house with cold air if the valve was not functioning. Almost all AC systems have an expansion valve that permits the refrigerant to expand into its normal low-pressure vapor state from a high pressure liquid state.
What happens when my main expansion valve is almost going bad?
- The air conditioner takes a long time to comfortably cool the home
- The air conditioned flow is much warmer than it really should be coming from the AC
