Oxbox J5GXCB004AC6HU Cased Evaporator Coil 1.5 to 3.0 Ton Upflow Downflow R-454B Residential Cooling

Product Description

The Oxbox J5GXCB004AC6HU is a B-cabinet cased evaporator coil rated for 1.5 to 3.0 ton residential split-system cooling applications. It is compatible with R-454B refrigerant, reflecting current low-GWP refrigerant standards adopted across new HVAC equipment lines. The coil ships factory-installed with a thermostatic expansion valve (TXV), which provides accurate refrigerant metering across the rated capacity range. All-aluminum coil construction improves corrosion resistance and supports long service life in varied installation environments. This coil is designed for upflow and downflow air handler orientations, giving installers flexibility in cabinet placement. Licensed HVAC technicians performing split-system installations or coil replacements are the primary service professionals for this component.

The J5GXCB004AC6HU is intended for residential central air conditioning split systems. Its B-cabinet cased design makes it suitable for pairing with a matched outdoor condensing unit in a forced-air ducted system. Web evidence confirms this coil has been offered as a matched indoor component alongside the Oxbox J5AC3030A1000AA 2.5 ton condensing unit in a 13.4 SEER2 system configuration. The upflow and downflow orientation support makes it adaptable to standard residential utility closet, basement, or attic air handler installations.

Key Features

• Factory-installed TXV for precise refrigerant metering across the 1.5 to 3.0 ton capacity range
• All-aluminum coil construction for enhanced corrosion resistance and durability
• R-454B refrigerant compatible, meeting current low-GWP refrigerant requirements
• B-cabinet cased design for a self-contained, field-ready installation
• Supports both upflow and downflow air handler orientations
• Oxbox by Trane product line, engineered for straightforward service and replacement

Compatibility

The J5GXCB004AC6HU has been paired with the Oxbox J5AC3030A1000AA 2.5 ton condensing unit in a 13.4 SEER2 split-system configuration. Beyond this documented pairing, this coil is designed as an OEM-style cased evaporator coil for residential R-454B split-system cooling applications within the 1.5 to 3.0 ton range. Verify matched-system efficiency ratings and compatibility with the outdoor unit before installation.

Installation Notes

Installation must be performed by a licensed HVAC technician in accordance with applicable mechanical codes and EPA Section 608 refrigerant handling regulations. Power to the air handler and outdoor unit must be fully de-energized at the disconnect and breaker before coil service begins. Because this system uses R-454B refrigerant, technicians should confirm they are using equipment rated and certified for A2L refrigerant handling prior to any line set connection or leak check procedures. Follow the manufacturer installer guide for evacuation, line set sizing, and low-voltage wiring requirements specific to the matched system.
