Carrier 48XZ042090300TP Expansion Valve
A split-system AC unit would not yield any cooled air if the valve was not doing its job. Expansion valves are used in AC systems and facilitates in helping the refrigerant to expand back into gaseous form from a high pressure liquid state.
How can I tell if my Carrier expansion valve is almost going bad?
- The air conditioned air is well below the temp it used to be blowing through the ductwork
- The outdoor AC unit takes its sweet time to properly cool
