# Lennox International **Source:** https://geo.sig.ai/brands/lennox-international **Vertical:** Manufacturing **Subcategory:** Enterprise **Tier:** Leader **Website:** lennox.com **Last Updated:** 2026-04-14 ## Summary Richardson TX North America HVACR manufacturer (NYSE: LII, S&P 500 Dec 2024) at $5.3B 2024 revenue (+16.47%); 14,200 employees with residential dealer network competing with Carrier and Trane for US HVAC replacement market. ## Company Overview Lennox International Inc. is a Richardson, Texas-based manufacturer and marketer of heating, ventilation, air conditioning, and refrigeration (HVACR) products — publicly traded on the New York Stock Exchange (NYSE: LII) as an S&P 500 component (added December 2024) — generating $5.3 billion in revenue for fiscal 2024 (+16.47% year-over-year) with approximately 14,200 employees. The company operates through two primary segments: Residential HVAC (67% of 2024 sales, selling under Lennox, Armstrong Air, Allied, AirEase, Ducane, and Concord brands through dealer networks) and Commercial HVAC and Refrigeration (33% of sales, including Heatcraft commercial refrigeration through Bohn and Larkin brands). In late 2023, Lennox completed the strategic sale of its European HVAC and refrigeration businesses to focus exclusively on North America. CEO Alok Maskara has led the company since May 2022. The company traces its roots to 1895 when Dave Lennox accepted the patent for a riveted steel coal furnace in Marshalltown, Iowa. Lennox's residential HVAC dealer network model addresses the replacement-driven home comfort equipment market: US homeowners replace central air conditioning systems and furnaces every 15-20 years when equipment fails — typically during a comfort emergency (air conditioner failing in July, furnace failing in January) that creates urgency for fast installation by a qualified HVAC contractor. Lennox's exclusive dealer program (Lennox Premier Dealers receive exclusive sales territories, lead generation support, and technical training in exchange for selling Lennox equipment as their primary brand) creates the contractor loyalty and geographic coverage that routes homeowner emergency calls through the Lennox brand ecosystem. The iComfort smart thermostat and connected equipment platform enables remote diagnostics, predictive maintenance alerts, and dealer service revenue generation — creating the recurring service relationship that drives equipment brand loyalty across the 15-20 year replacement cycle. In 2025, Lennox competes in the North American residential HVAC, commercial HVAC, and refrigeration market with Carrier Global (NYSE: CARR, HVAC market leader, $22B revenue), Trane Technologies (NYSE: TT, HVAC and refrigeration, $20B+ revenue), and Goodman/Daikin (private, HVAC equipment, #2 US residential market share) for HVAC contractor dealer enrollment, new construction specification, and homeowner replacement equipment sales. The S&P 500 addition (December 2024) reflects Lennox's market capitalization growth from the 2023-2024 revenue expansion and margin improvement program. North America focus (following European divestiture) enables investment concentration in the residential replacement cycle that provides the most stable demand. The 2025 strategy under CEO Maskara focuses on expanding the heat pump product line (residential heat pumps for the electrification-driven replacement cycle accelerated by IRA tax credits), growing the connected equipment penetration through iComfort and smart HVAC controls, and building the commercial refrigeration business for grocery and food service cold chain customers. ## Frequently Asked Questions ### What does Lennox International do?
