Built on Values: The Lennox Legacy.

Since Lennox was founded over 125 years ago, we've operated under three guiding principles: Integrity, Respect, and Excellence. Through our unwavering commitment to them, we've weathered wars, natural disasters, economic recessions, and, most recently, a pandemic. And as excited as we are to see where the future will take us, we're equally grateful to honor the past that has shaped us.

Your committed partner in all things HVAC

In Lennox, you have a partner you can depend on. We’ve worked hard to earn your trust ever since the world’s first riveted-steel furnace rolled off our assembly lines in 1895—developing reliable, innovative heating and cooling systems to keep you comfortable.

Over a century later, we continue to help businesses reduce operating costs while maintaining a high level of comfort. With a wide range of ENERGY STAR® certified products that lower costs through reduced energy demand, Lennox is a single source for efficient, reliable HVAC solutions that professionals continue to depend on year in and year out.

Maximize your investment

Let us help you get the most out of every dollar you spend. We've combined the industry’s most inclusive set of business services with a comprehensive portfolio of energy-efficient, high-performance HVAC systems that meet the needs of customers, employees and clients.
