Constant comfort and efficiency
The ML180E’s Power Saver™ constant torque motor adjusts airspeed based on demand, helping the furnace use less energy in both heating and cooling modes.
Heating performance that won't drive up utility costs
When compared to a standard single-speed motor, the Power Saver motor delivers significant energy savings, without sacrificing comfort.
Keeping you comfortable and energy smart
The ML180E has an AFUE of 80%, which means that 80 cents of every dollar spent on gas goes directly to heating your home. With an ML180E furnace, you could be saving hundreds of dollars every year when compared to an older, less efficient unit.
Dual-fuel operation for even greater efficiency
When the ML180E is paired with a Lennox® heat pump, it creates a system that automatically switches between electricity and gas, keeping you warm and energy efficient.
Comfort you can rely on
From its heavy-gauge cabinet and ArmorTuf™ aluminized steel heat exchanger to its tightly-sealed blower compartment, the ML180E is built to deliver years of dependable comfort.
