Reliable heating in low ambient temperatures

AAON Alpha Class air-source heat pumps are capable of operating reliably at lower ambient temperatures and with high heating capacities over a wide range of operating conditions. AAON Alpha Class heat pumps perform well in climates where other solutions cannot.

High-efficiency electrified heating & cooling

AAON Alpha Class air-source heat pumps have AHRI-certified heating COPs of up to 3.7 and cooling IEER values up to 21.5, saving energy costs year-round.

Precise comfort control without burning fossil fuels

Variable speed compressor heat pump heating combined with an auxiliary modulating electric heater allows comfortable heating control, even in extreme temperatures without the use of fossil fuels.

AAONAIRE® energy recovery

The addition of AAONAIRE energy recovery wheels significantly increases the efficiency of AAON Alpha Class units to maximize energy savings. Selecting this feature increases the COP of the system significantly and also provides more effective performance by preconditioning the outside air.

Renowned cabinet design and construction

Standard two-inch rigid polyurethane foam-injected panels have a thermal resistance R-value of 13 or greater, exceeding that of a cabinet with four-inch fiberglass construction. This retains useful heating to the building instead of wasting it through the cabinet.

Wide range of available capacities

AAON Alpha Class air-source heat pumps are available from 2-70 tons.
dualfuel icon

Dual Fuel

In addition to the 100% electric configuration, AAON provides the option to select a supplemental gas heater to provide heat in situations that require it. The gas heat is only used in extremely low-ambient temperatures, greatly reducing overall fossil fuel usage while providing comfort in all conditions.

Economizer Option

Up to 100% airflow economizer dampers provide energy-saving, free conditioning when conditions meet setpoint values. This feature also provides ventilation air under all conditions to meet indoor air quality requirements with fresh outside air.
speed fan

Variable speed fans

Variable speed supply fans and variable speed outdoor fans provide high performance heat pump heating and cooling airflow. Variable speed control allows for energy savings at reduced airflow.

Variable speed compressors

These operate with the highest part load efficiencies over any other compressor technology and provide precise temperature and humidity control. Specific controls protect the compressor by ensuring it operates within the safety of the compressor operating envelope.

Modulating hot gas reheat capacities

Modulating hot gas reheat humidity control is available to provide energy efficiency dehumidification, even with low sensible heat loads, without the temperature swings common with on/off reheat systems.
