SPT WA-1010E Expansion Valve
Your main AC unit would produce no cooled air if it were lacking a functioning expansion valve. Every air conditioning system contains an expansion valve that makes it easier for the refrigerant to expand back into vapor form from a high pressure liquid state.
General warnings to watch for in a failing main expansion valve
- Your AC takes too long to comfortably cool as it should
- Air flow is definitely not as cold as than the usual air comes through the ducts
