Heat Pump Split Systems

Oxbox J5HP5 outdoor heat pumps paired with J5AH4P multi-position air handlers deliver year-round heating and cooling on low-GWP R-454B refrigerant. These Trane-engineered split systems are rated up to 14.3 SEER2 (up to 15.2 SEER2 with matched indoor equipment). The J5HP5 uses a scroll compressor, compact galvanized steel cabinet, and a corrosion-resistant coil with hydrophilic coating. Units are factory-charged for 15 ft of line set and designed for quiet outdoor operation. The J5AH4P air handler uses a multi-speed PSC blower and an all-aluminum coil. It installs up-flow, down-flow, or horizontal left/right, with a rust-resistant painted cabinet, dual drain connections, and slide-out blower/coil assemblies for service. Optional electric heat kits are available. Installer-friendly replacements for older R-410A equipment. Ideal for residential replacements and new installs that need a durable, code-ready R-454B heat pump system.
