Description
The Lennox 25W22 is an OEM thermostatic expansion valve (TXV) engineered as a direct replacement for compatible Lennox cooling systems. Thermostatic expansion valves are critical refrigeration components that regulate the flow of refrigerant into the evaporator coil, maintaining optimal superheat levels and maximizing system efficiency and comfort.
Why Replace Your TXV?
A failing or improperly calibrated TXV can lead to poor cooling performance, compressor damage, iced evaporator coils, and reduced system efficiency. Installing a genuine Lennox OEM replacement valve restores proper refrigerant metering and protects the overall refrigeration circuit.
