International Comfort Products PGMD42G115 Expansion Valve
Your HVAC system expansion valve facilitates in helping the refrigerant to expand back to its low-pressure vaporous form from a high-pressure liquid form. A split-system AC unit would not yield any cooled air if it were lacking a functioning expansion valve.
Do you know if your refrigerant expansion valve is not working right?
- The outdoor AC unit takes its sweet time to keep the temperature down
- The cooled air is not as cold as it really should be coming out of the vents
