International Comfort Products PAPA30GA1 Expansion Valve
Pretty much every air conditioning system has an expansion valve that allows the refrigerant to expand back to its low-pressure gas state from a liquid. Your AC cannot possibly cool the house if the valve was not functioning.
How do you know when your main expansion valve is about to stop working?
- The cold airflow is definitely not as cold as than the usual air coming from the air handler
- AC takes forever in a bid to keep things cool
