Description
The Lennox 25W27 is a genuine OEM thermostatic expansion valve (TXV) engineered to deliver precise refrigerant metering and optimal system performance in compatible Lennox HVAC equipment. Replacing a worn or failed TXV with the correct OEM part ensures your system operates at its designed efficiency rating, protecting the compressor and maintaining consistent comfort.
Why Replace with the Lennox 25W27 TXV?
A thermostatic expansion valve is a critical refrigerant-side component responsible for regulating the flow of liquid refrigerant into the evaporator coil. A faulty TXV can cause symptoms such as poor cooling, icing on the evaporator, high superheat, or compressor damage. Using the factory-specified 25W27 replacement ensures proper superheat control and a reliable, long-lasting repair.
