Innovation that's always a warm welcome.

The industry's most efficient furnaces.
Lennox® furnaces have efficiency ratings from 80% all the way up to an industry-leading 98.2% AFUE. And many are ENERGY STAR® qualified, which means you can significantly lower your utility bills, compared to older or conventional models.
The quietest furnace you can buy.
Some manufacturers talk about their systems being quiet. But we feel performance speaks louder than words. That's why we engineered our furnaces to deliver exceptional comfort, without hardly making a sound.
Designed for absolute comfort.
The basic job of a furnace is to keep you warm. Lennox® furnaces go many degrees beyond with innovations like Precise Comfort technology, which creates perfect temperature and humidity by varying heat output in increments as small as 1%. |
