Lennox® furnaces are some of the most efficient and quietest heating systems you can buy*. They’re engineered for perfect warmth and savings. Innovations like Precise Comfort® technology allow the furnace to keep the temperature held exactly where you want it. Heat is even throughout your home, with no cold spots. If it sounds perfect, it’s because it is.
More efficient than anything the industry has ever seen, Lennox furnaces boast an efficiency rating of up to 99% — that means it essentially converts every last bit of energy it uses into heating the home. When a gas furnace is installed with a compatible Lennox heat pump, it creates a heating system that can switch back and forth between electricity and gas automatically, based on whichever is the most cost-efficient for the weather conditions at the time.
