An AFUE of 80% means 80 cents of every dollar spent on gas goes directly toward heating your home. That can mean potential savings of hundreds of dollars per year when compared to an older furnace.
From its heavy-gauge steel cabinet and aluminized steel heat exchanger to its sealed blower compartment, the ML180 is built to deliver reliable comfort, year after year.
When the ML180 is paired with a Lennox® heat pump, it creates a system that can automatically alternate between electricity and gas to keep you warm. So you’re always using the most energy-efficient way to keep comfortable.
