Harold James, Inc is proud to offer commercial heating and cooling products from AAON. AAON is a world leader in creating comfortable and healthy indoor environments, efficiently, through the manufacture of premium HVAC equipment. AAON specializes in chillers and air conditioning units but offers a variety of equipment to its customers.

When you work with AAON you’ll have access to both indoor and outdoor air handling units, condensers, chillers, self-contained units, geothermal heat pumps, air source heat pumps, and pool room units.

Air Handling Units

AAON air handling units are engineered for performance, flexibility, and serviceability. Double wall rigid polyurethane foam insulated cabinet construction and direct drive backward curved plenum fans allow units to have quiet, energy efficient airflow with high static pressure capabilities. The air handling units can be matched with AAON condensing units or an AAON chiller for a complete system.

Packaged Rooftop Units

AAON rooftop units are engineered for performance, flexibility, and serviceability. Double wall rigid polyurethane foam insulated cabinet construction and direct drive backward curved plenum fans allow the units to have quiet, energy efficient airflow with high static pressure capabilities. The lockable hinged doors provide easy access to all sections of the unit for servicing.

Water Source Heat Pumps

AAON manufactures Water-Source Heat Pump (WSHP) Rooftop Units, Vertical Self-Contained Units, and Modular Air Handling Units with capacities ranging from 2-230 tons. AAON offers all of these units with mass customization or the ability to configure the features and options of the unit at the factory to meet nearly any application’s requirements.

These products may be used as Makeup Air ventilation units, Variable Air Volume (VAV) units, or Single Zone VAV units with variable capacity cooling and variable speed supply fans.

Air Source Heat Pumps

AAON air-source heat pumps can provide energy efficient cooling and heating using the unit’s refrigeration circuit. Reversing the flow of the unit’s refrigeration circuits allows the indoor coil to be used as a heating coil. This is a more efficient method of heating than electric resistance heating because a heat pump can reject more heat to the space per the amount of energy used.
