Allied Air 16G89 Multi-position Air Handler 4 Ton

Product Description

The ALLIED AIR 16G89 is a multi-position blower coil air handler rated at 4 nominal tons, designed for split-system cooling and heat pump applications in residential and light commercial settings. The unit ships with an expansion valve (TXV) factory-installed, eliminating the need for a field-supplied metering device and supporting more precise refrigerant management across a range of operating conditions. Its compact cabinet profile allows installation in upflow or downflow orientations, giving installing technicians flexibility when working with constrained mechanical rooms or closet installations. The unit measures 55 inches tall, 21.5 inches wide, and 22 inches deep.

The 16G89 is suited for residential new construction and retrofit projects where a multi-position, enhanced blower coil unit is required. The compact form factor makes it practical for tight utility closets, alcoves, and basement installations where a full-size air handler may not fit. Licensed HVAC technicians typically specify this unit alongside a matched outdoor condensing unit or heat pump as part of a complete split system.
