A Legacy of Vision and Innovation
Lennox Heating Cooling 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.
As a leading innovator of home Lennox heating cooling and air-quality systems, we’re committed to making people feel comfortable in their home environments, which includes a commitment to protect the global environment.
Our commitment begins at our research and development laboratories. Every product we manufacture must meet our exacting standards for reliability to ensure lasting value and performance. Our approach is simple: the better the design, the fewer new materials needed to keep the equipment running.
