Lennox CB30U-46 Expansion Valve
An expansion valve allows the coolant to expand back to its low-pressure gas state from a liquid. The AC in a split system would be broken if it were to lack a properly working expansion valve.
Major indications your refrigerant expansion valve will have to be replaced
- The air conditioned flow is not as cool as than the usual air for the AC to cool the house
- The outdoor AC unit takes too long in its attempt keep things cool
