Carrier 58MVB040F10114 Expansion Valve
An expansion valve permits the refrigerant to expand back to its low-pressure vaporous form from a high-pressure liquid form. The AC in your house could not cool the air without a working expansion valve.
What red flags are there that my AC expansion valve is not working properly?
- Your cooling system takes its sweet time to actually cool as it should
- The cooled air is not as cool as than the usual air coming from the vents
