Lennox G40UH-48B-090 Expansion Valve
An expansion valve makes it easier for the refrigerant to expand back into vaporous form from its highly pressured liquid form. Your main AC unit would not yield any cooled air if the valve was not working.
Some warnings of a dying Lennox expansion valve
- The cool flow of air is not as cool as you are accustomed to exiting the air handler
- AC takes a long time trying to keep the home at a comfortably cold temperature

If you decide on picking up or purchasing, do your due diligence and cross-check the correct model as well as make a visual comparison in order to be sure the correct expansion valve is being ordered. You do not have to install the replacement part alone. Find a professional in your town or city to do the job for you.
