From a single product line to a global HVAC solutions provider serving every major commercial and industrial sector.
LennoxAir began as a regional heat pump manufacturer, supplying packaged rooftop units to commercial buildings across the American Southwest. Our first product line featured fixed-speed air-source heat pumps with EER ratings that set new benchmarks for the era.
Opened our first overseas production facility and service center network. By the mid-1990s, LennoxAir equipment was operating in 18 countries across North America, Europe, and the Middle East.
Expanded into condensers, evaporator coils, and digital thermostat controls. This vertical integration allowed us to deliver fully matched HVAC systems optimized for performance and reliability.
Launched our variable-speed inverter compressor platform, achieving SEER ratings up to 20 and 30-50% energy savings at part-load conditions. This technology became the foundation of our next-generation heat pump line.
Began shipping heat pumps with R-32, R-454B, and R-290 refrigerant options. Committed to having low-GWP alternatives available across 85% of our product portfolio by 2028.
LennoxAir operates 5 production facilities, 38 service centers, and employs 1,850 people globally. Our installed base exceeds 180,000 units across commercial buildings, hospitality, healthcare, education, and light industrial applications.
Every product is tested beyond rated conditions. Our 140-person R&D team validates performance across 120% capacity, extreme ambient temperatures, and accelerated lifecycle simulations before any unit reaches production.
We design for 20-year lifespans, not 5-year replacement cycles. Our compressors are rated for 80,000+ operating hours, and our heat exchangers use corrosion-resistant alloys in all coastal and industrial environments.
38 service centers, 24/7 emergency dispatch, and a 98.4% first-visit resolution rate. When your HVAC system needs attention, our technicians respond fast and carry the parts to fix it right the first time.
Whether you are a facility manager, consulting engineer, or mechanical contractor, we would like to discuss how LennoxAir can support your next project.
