International Comfort Products FBF100F20A3 Expansion Valve
Almost all AC systems have an expansion valve that makes it easier for the refrigerant to expand back into vapor form from a high-pressure liquid form. A split-system AC unit would probably blow heated air if the valve was not working.
What are some hints that my expansion valve is in need of replacing?
- The cooled air is not cold enough as than the usual air coming out of the vents
- The outdoor AC unit takes too long in attempting to cool all the rooms in your house
