Lennox XP19-048 Expansion Valve
A normal AC expansion valve allows the refrigerant to spread back into vapor state from a high-pressure liquid form. Your AC unit can not deliver properly cooled air if the valve was not working.
Some clues of an ineffective AC expansion valve
- AC unit takes too long to actually cool your home
- The cooled air is not cold enough as it really should be coming into the home
