Furnaces


Designed to deliver reliable and economical warmth, Lennox furnaces have efficiency ratings from 80% all the way up to 98.2% AFUE. And many are ENERGY STAR qualified, which means they can significantly lower your utility bills, compared to conventional models. For optimal comfort and efficiency, a gas furnace can be combined with an electric heat pump in one dual-fuel system. Act quickly to take advantage of tax credits available on select gas furnaces.
