Carrier 58MCA Expansion Valve
Your HVAC system expansion valve allows the refrigerant to expand back into vapor form from a high-pressure liquid form. An AC system could not cool the air without a working expansion valve.
What are the indications that my AC expansion valve is almost dead?
- The air conditioned flow is definitely not as cold as you are accustomed to coming from the AC
- AC unit takes a really long time trying to cool all the rooms in your house
