In 1895, Dave Lennox recognized a critical gap in home heating: cast iron furnaces were inefficient and prone to cracking. So he invented the world's first riveted-steel furnace - a breakthrough that would launch a legacy of innovation spanning more than 130 years. What began in a Marshalltown, Iowa machine shop has evolved into Lennox International (NYSE: LII), a global leader in climate control solutions serving heating, ventilation, air conditioning, and refrigeration markets across 70+ countries. The company pioneered residential forced-air heating in 1923, introduced the industry's first high-efficiency gas furnaces in 1973, and continues to push boundaries with energy-efficient systems that reduce environmental impact.
Today, Lennox operates through three strategic business segments: Home Comfort Solutions delivers premium residential HVAC equipment through the Lennox Residential brand; Building Climate Solutions provides commercial systems via Lennox Commercial and Heatcraft Refrigeration brands (including Bohn, Larkin, Climate Control, and Chandler); and Parts & Supplies distributes components through LennoxPros, Duro Dyne, and Supco. Guided by core values of Integrity, Respect, and Excellence, the company employs 14,200 people across major manufacturing facilities in Iowa, South Carolina, and Mexico. Lennox combines direct-to-network distribution with cutting-edge digital tools to support dealers and contractors while maintaining relentless focus on sustainability - developing products that achieve industry-leading SEER efficiency ratings and help reduce carbon footprints for residential and commercial customers worldwide.
