Description
The Lennox 25C02 is a factory-engineered Thermostatic Expansion Valve (TXV) designed specifically for R-410A refrigerant systems in the 3.5 to 5 ton capacity range. As a precision metering device, the TXV automatically regulates refrigerant flow into the evaporator coil in response to changing load conditions, maintaining optimal superheat and protecting the compressor from liquid slugging.
Designed as a genuine Lennox OEM replacement component, the 25C02 ensures a drop-in fit for compatible Lennox air conditioning and heat pump systems. Using an OEM-matched TXV preserves system efficiency ratings, maintains warranty compliance, and eliminates the guesswork associated with aftermarket alternatives.

Why Choose an OEM TXV?
A properly matched TXV is critical to system performance. An undersized or oversized valve can cause hunting, poor dehumidification, reduced efficiency, and premature compressor failure. The Lennox 25C02 is engineered to the exact specifications of your system, ensuring stable superheat, maximum efficiency, and long-term reliability.
Important Note
Always verify compatibility with your specific Lennox model before installation. Consult the equipment’s service manual or contact a licensed HVAC technician to confirm the correct TXV for your application.
