Why Upgrade or Replace with the Lennox 11N92?
A properly functioning TXV is critical to system efficiency and compressor longevity. The Lennox 11N92 restores precise refrigerant flow control, preventing both overfeeding and underfeeding of the evaporator coil. By maintaining the correct superheat, this valve helps the system run at rated SEER efficiency and reduces wear on the compressor — making it an essential component for any Lennox system service or coil replacement.
