AAON manufactures commercial and industrial HVAC equipment engineered for energy efficiency and configurability — packaged rooftop units, air handling units, self-contained systems, split systems, condensing units, and a growing heat pump lineup (air-source, water-source, and geothermal). 

Their equipment is built for demanding continuous-use environments like healthcare, education, data centers, and hospitality, with strong options for electrification and decarbonization projects. 

AAON's Alpha and Delta Class lines target facilities pursuing low-GWP refrigerant transition (R-454B) and dedicated outdoor air system (DOAS) performance, while their controls platform integrates directly for full building automation — delivering long equipment life, factory-tested reliability, and systems that scale from small retail rooftop units up to 261-ton commercial installations.
