International Comfort Products TCH248AKA1 Expansion Valve
Your HVAC system expansion valve makes it easier for the refrigerant to expand back to its low-pressure gas state from a high-pressure liquid form. A split-system AC unit can not supply your house with cold air if the valve was worn out.
Subtle hints the expansion valve is failing
- AC air production is much warmer than it really should be blowing through the ductwork
- AC unit takes too long trying to keep the home at a comfortably cold temperature
