Lennox G40UH-36A-070X Expansion Valve
A split-system AC unit would be impossible to cool the home without the valve working properly. Pretty much every air conditioning system has an expansion valve that facilitates in helping the refrigerant to expand back to its low-pressure vapor form from a liquid.
What are some hints that my Lennox expansion valve has a need to be replaced?
- Your AC unit takes forever in attempting to bring down the temperature
- Air from the AC is definitely not as cold as it should be for the AC to cool the house

If you are unsure about the properly replacing the new expansion valve on your own then it may be wise to consult a pro to do the work for you.
