Lennox G43UF-36C-090H Expansion Valve
Almost all AC systems have an expansion valve that allows the coolant to expand back into its natural vaporous form from its highly pressured liquid form. A split-system AC unit could not cool the air without the valve working properly.
What are the clues to watch out for to know my main expansion valve is in need of a replacement?
- Your cooling system takes its sweet time to appropriately cool as it should
- AC air production is not as cold as it should be coming from the air handler
