Lennox:  the very finest in heating, cooling and indoor air quality

A Legacy of Vision and Innovation

Among the pioneers of modern home comfort, no one stands taller than Dave Lennox. Working from his machine shop in Iowa, he single-handedly elevated the American standard of living by building the first Lennox® furnaces.

For more than 100 years, Lennox has been at the forefront of residential heating and cooling innovation.  Lennox is built on a legacy of innovative firsts, from the introduction of the riveted-steel furnace in 1895 to some of the most efficient air conditioners available today. Over the years, Lennox has set the standard for home comfort, and we continue to push the standard forward with a lineup of more than 60 leading-edge products and a network of more than 6,000 full-service dealers.  Today Lennox provides some of the industry's best air conditioning units, continuing its long-standing tradition of excellence.
