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.
Constant torque, constant efficiency
The Power Saver™ constant-torque motor adjusts airspeed based on demand. This helps the furnace use less energy in both heating and cooling modes.
Powerful energy savings.
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 year-round, while still keeping your home warm and quiet. It may even help you qualify for energy rebates.
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.
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.
