Lennox G40UH-36B-090 Expansion Valve
Your AC can not deliver properly cooled air without a working expansion valve. Pretty much every air conditioning system has an expansion valve that allows the refrigerant to expand back to its low-pressure gas state from a high pressure liquid state.
Subtle cues of a declining Lennox expansion valve
- Your cooling system takes way too long in attempting to cool as it should
- The air is not as cold as it ought to be coming into the house
