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.

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.

This furnace is compatible with the Lennox E30 Smart Thermostat, giving you easier access, control, and comfort. And because the E30 works seamlessly with a range of smart home devices, you get the added convenience of perfect comfort being just a tap or voice command away.
