Features
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, meeting the strictest air quality requirements. So you can feel good about your environment, inside and out. These NOx, or Nitrogen Oxide, emissions from furnaces produce ground-level ozone, which impacts the environment and your health.
Two-stage operation for more balanced temperatures
A step up from single-stage furnaces because its gas valve offers an additional lower setting. Most of the time the unit will meet heating needs at its lower stage, resulting in balanced and consistent temperatures with lower energy use. Should the low heat setting not heat the space quickly enough, the furnace will switch to the high setting. This ability to switch between the two settings offers greater comfort and efficiency.
Energy efficiency that adapts to 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.
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.
Annual Fuel Utilization Efficiency, or AFUE, measures how efficiently your furnace uses fuel. An energy rating of 80% AFUE means this furnace can significantly reduce your heating costs, compared to an older furnace.
We have higher standards. Others think so, too.
High quality, tough and dependable
