Oxbox J4PH4042E1000A 3.5 Ton Heat Pump Packaged Unit

Product Description

The OXBOX J4PH4042E1000A is a 3.5-ton, horizontal-discharge heat pump packaged unit designed for residential and light-commercial applications where space is limited or a split system is not practical. The unit runs on R-410A refrigerant and carries a 13.4 SEER2 efficiency rating, meeting current federal minimum efficiency standards. All heating and cooling components are housed in a single steel cabinet, eliminating the need for a separate indoor air handler or furnace. Licensed HVAC technicians install this unit in horizontal-only orientations, typically on a rooftop curb or ground pad with horizontal duct connections.

This packaged unit suits residential replacement and new-construction projects where a combined heating and cooling solution is required in a compact footprint. The horizontal-only configuration makes it well suited for rooftop installations or tight utility areas where vertical discharge is not an option. The heat pump operation provides both heating and cooling from one cabinet, reducing the number of system components and potential failure points on the job.
