Oxbox J5PH4030A1000A Packaged Heat Pump Unit 2.5 Ton 13.4 SEER2 R-454B Single Phase

Product Description

The Oxbox J5PH4030A1000A is a 2.5-ton packaged heat pump unit engineered for year-round residential and light commercial heating and cooling. This single-stage system operates on R-454B refrigerant and delivers a 13.4 SEER2 efficiency rating, meeting current federal minimum efficiency standards. Rated for single-phase, 208/230-volt power, the unit is configured for horizontal discharge and houses the compressor, coil, and air handler in one self-contained cabinet. Licensed HVAC technicians install and commission this equipment as a complete, all-in-one solution where space or ductwork layout favors a packaged configuration over a split system.

The J5PH4030A1000A is suited for residential applications and light commercial installations where a single outdoor cabinet handles both the heating and cooling load. Packaged heat pump units are commonly installed on rooftops, ground-level pads, or side-wall platforms with direct duct connections into the conditioned space. The horizontal discharge design simplifies duct runs in low-clearance or rooftop mounting scenarios. Oxbox is a Trane brand, and this unit reflects that engineering lineage while targeting cost-conscious projects that still require dependable, code-compliant performance.

• Horizontal discharge design suited for rooftop and ground-pad installations
• Architecturally compatible cabinet with anti-rust construction for long-term outdoor exposure

Compatibility

Designed as a self-contained OEM packaged heat pump unit for residential and light commercial applications requiring a single-phase, 208/230-volt, R-454B-compatible system. The J5PH4 series is available in 2-ton through 5-ton capacities within the Oxbox packaged heat pump lineup.

Installation Notes

Installation must be performed by a licensed HVAC technician holding current EPA Section 608 certification for R-454B refrigerant handling. Disconnect and lock out all electrical power before making any electrical or refrigerant connections. Follow local mechanical and electrical codes, including applicable sections of the International Mechanical Code and NEC, for equipment mounting, disconnect sizing, and duct connection requirements. At 326 pounds, this unit requires appropriate lifting equipment and a minimum two-person installation crew for safe placement on a pad or rooftop curb.
