Description
The Lennox 29M89 is an OEM thermostatic expansion valve (TXV) engineered as a direct replacement for compatible Lennox cooling and heat pump 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 across varying load conditions.
Key Features
- OEM Lennox replacement TXV valve — ensures proper fit and function
- Precisely regulates refrigerant flow to the evaporator coil
- Maintains consistent superheat for peak system efficiency
- Engineered for compatibility with Lennox cooling and heat pump equipment
- Durable construction for long-lasting, reliable operation
- Helps protect the compressor from liquid refrigerant slugging
Why Replace Your TXV?
A faulty thermostatic expansion valve can cause a wide range of system issues including poor cooling performance, high superheat, low suction pressure, and compressor damage. Replacing a worn or failed TXV with a genuine Lennox OEM part restores proper refrigerant metering and ensures your system operates within design specifications.
Application
- Designed for use in compatible Lennox air conditioning and heat pump systems
- Intended for installation by qualified HVAC technicians
- Consult your equipment’s service manual to confirm compatibility before installation
