AAON Introduces Alpha Class Heat Pump with Copeland Variable-Speed Compressors

AAON has launched its new Alpha class air-source heat pump rooftop unit, integrating Copeland's variable-speed compressor technology to meet the growing demands for energy efficiency and electrification in commercial HVAC systems.  

The Alpha class units utilize the Copeland variable-speed scroll compressor, developed by Copeland, to offer enhanced modulation and energy savings. According to AAON, the system is optimized to achieve high heating performance with a low Global Warming Potential (GWP) refrigerant—R-454B. The Alpha units range from 1.5 to 23 tons and are designed for variable capacity operation in both heating and cooling modes.  

The units support advanced heating capacity at ambient temperatures as low as -10°F and can maintain full heating performance at 0°F. The design includes fully modulating compressor and fan systems, onboard digital controls, and variable-speed EC motors.  

“Trane Technologies and Copeland are helping us transition to environmentally friendly and efficient HVAC technologies,” said Gary Fields, president and CEO of AAON. “By incorporating Copeland’s variable-speed compressor platform, we are pushing the boundaries of how buildings are heated and cooled using clean energy.”  

The Copeland variable-speed compressors used in the Alpha class units are designed for high efficiency and precise temperature control, allowing for year-round comfort in commercial HVAC settings. Each compressor includes onboard variable frequency drives and integrated electronics to support connectivity and control strategies.  

“The HVAC industry is at the forefront of global climate strategies,” said John Schneider, president of Copeland. “This technology partnership with AAON reflects a shared commitment to decarbonization and energy efficiency through advanced heat pump development and next-generation refrigerants.”  

AAON’s announcement aligns with current industry trends aiming to improve energy performance and reduce greenhouse gas emissions in building systems. The Alpha class systems are available for commercial buildings including schools, offices, and healthcare facilities seeking all-electric heating and cooling alternatives.
