Smarter Together
Beyond Quiet

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.
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.
Annual Fuel Utilization Efficiency, or AFUE, measures how efficiently your furnace uses fuel. An energy rating of up to 97% AFUE means this furnace can lower your energy bills by 20% compared to a standard furnace, while still keeping your home warm and quiet. It may even help you qualify for energy rebates.
This product is eligible for the Energy Efficient Home Improvement Credit (Internal Revenue Code Section 25C), a federal tax credit provided to homeowners who install high-efficiency equipment. You can potentially receive hundreds of dollars with tax credits. Consult your tax professional to confirm eligibility.
Heating, ventilation and air-conditioning (HVAC) equipment with the ENERGY STAR label meets or exceeds federal guidelines for energy-efficient performance. An ENERGY STAR-certified furnace can reduce heating costs by 15 percent.
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.
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.

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.
The Power Saver™ constant-torque motor adjusts airspeed based on demand. This helps the furnace use less energy in both heating and cooling modes.
