Carrier 25HNA936A0030030 Expansion Valve
Your HVAC system expansion valve makes it easier for the refrigerant to spread back into gas state from a high pressure liquid state. An AC would not produce cooled air if the valve was not functioning.
What are some hints that my main expansion valve is in need of a replacement?
- Air flow is much warmer than it used to be exiting the vents
- Your AC takes a long time in attempting to cool the indoors
