Product Description

The HISENSE AHU-24U3T24 is a 24,000 BTU indoor heat pump air handler designed for high-efficiency split-system installations. Operating on 230 volts and rated at 20 SEER, this unit uses R-454B refrigerant, a lower-GWP alternative to R-410A that meets current environmental standards. It is part of the Hi Pro HD product line and serves as the indoor component of a matched heat pump system. Licensed HVAC technicians install this unit in residential and light commercial applications where both heating and cooling are required from a single system.

This air handler is suited for residential and light commercial split-system heat pump configurations where high-efficiency performance and R-454B refrigerant compatibility are required. The 20 SEER rating supports compliance with current minimum efficiency regulations in applicable regions. It is intended for use as the indoor section paired with a compatible HISENSE outdoor condensing unit. The AUH-2424 designation referenced in the product data may indicate a matched or related system configuration.
