Features
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.
Use Less Energy. Save More Money.
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.
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.
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.
