AAON designs and manufactures HVAC equipment for commercial, industrial, and data center applications. The company operates two product brands: AAON for commercial and industrial HVAC, and BASX for data center and cleanroom cooling. The core AAON-branded product is the rooftop unit (RTU), a self-contained heating and cooling system for commercial and industrial buildings, offered across a wide capacity range. AAON also manufactures air handlers, heat pumps, and energy recovery units, and argues it differentiates on energy efficiency and configurability rather than price. A growing focus is the Alpha Class air-source heat pump, which operates in temperatures as low as -20°F and targets customers pursuing building electrification. BASX, acquired in 2021, engineers custom thermal management solutions for hyperscale and colocation data centers, including airside cooling and a liquid cooling portfolio anchored by a proprietary Coolant Distribution Unit (CDU). BASX targets high-density AI and HPC workloads and co-engineers purpose-built solutions directly with hyperscalers. AAON sells commercial HVAC through independent sales reps and BASX products directly through engineering partnerships with large data center operators. AAON builds entirely to order, limiting inventory risk but creating sensitivity to production throughput. Key cost inputs are steel, copper, and aluminum, with significant vertical integration that AAON argues provides a tariff advantage over competitors relying on international supply chains. AAON's growth strategy centers on scaling BASX data center revenue and gaining commercial HVAC share through national accounts and the Alpha Class product line.
