Lennox XP14-042 Expansion Valve
Every air conditioning system contains an expansion valve that allows the refrigerant to expand back into its natural vaporous form from a liquid. The AC in a split system would be impossible to cool the home if the expansion valve was worn out.
Simple signals the expansion valve is going out
- Air from the AC is much warmer than it ought to be coming into the home
- The outdoor AC unit takes too long to actually bring down the temp in the house

Before buying or purchasing, do your due diligence and make sure of the correct model and also make a visual comparison in order to be sure the correct expansion valve is being ordered. You do not need to install the replacement part alone. Search for a pro in your area to replace the part.
