Features
Balanced comfort and efficiency
While most furnaces are single stage, meaning they're either on or off, this furnace can heat at two different speeds. Most of the time the unit will meet heating needs at its lower speed, resulting in balanced and consistent temperatures with lower energy use.
Energy efficiency that adapts to meet your needs.
Equipped with an efficient variable-speed blower motor with the ability to slowly ramp the airflow up or down to provide consistently even temperatures as it only produces the necessary amount of airflow at any given time.
The perfect amount of quiet.
Made with a fully insulated cabinet, special sound-absorbing materials and sturdy burners to reduce noise, this furnace is designed to operate extremely quietly, so you can relax in peaceful warmth.
Digitally intelligent for accuracy and efficiency
This truly digital product is designed to pair with the Lennox S40 Smart Thermostat as part of a fully communicating home comfort system. Sensors in the equipment allow the thermostat to diagnose issues and automatically make system adjustments to more accurately and efficiently maintain temperature, humidity and air quality.
Fewer emissions is our mission
Along with the state of California, we’re leading the way with low-NOx initiatives and solutions. Efficient and environmentally friendly, our revolutionary design produces 65% lower NOx emissions than standard low-NOx furnaces. So you can feel good about your environment, inside and out. These NOx, or Nitrogen Oxide, emissions from packaged units produce ground-level ozone, which impacts the environment and your health.
A refrigerant that’s better for the environment.
This product is compliant with 2025 EPA regulations for lower global warming potential (GWP) refrigerants. The Lennox choice of 2025 Compliant Refrigerant has a lower GWP than its predecessor and is formulated to provide excellent, reliable performance of your system for years to come.
