Oxbox J5PH4036A1000A Packaged Heat Pump Unit 3 Ton 13.4 SEER2 R-454B Single Stage

Product Description

The Oxbox J5PH4036A1000A is a 3-ton, single-stage packaged heat pump unit designed for year-round heating and cooling in residential applications. Running on R-454B refrigerant and rated at 13.4 SEER2, it meets current federal efficiency standards. With a nominal heating and cooling capacity of 36,000 BTU/h, this self-contained unit houses the compressor, coil, and air handler in a single cabinet, simplifying installation and reducing rooftop or ground-level footprint. Licensed HVAC technicians handle installation, commissioning, and refrigerant handling for this equipment.

The J5PH4036A1000A is suited for residential replacement and new-construction applications where a fully packaged solution is preferred over a split system. Its single-cabinet design is common on rooftop applications and ground-level pads where interior mechanical space is limited. The unit operates on 208/230-volt, single-phase, 60 Hz power, making it compatible with standard residential electrical service. It is an appropriate choice where local code or jobsite conditions favor packaged equipment over separate indoor and outdoor components.

Key Features

• 3-ton nominal capacity with 36,000 BTU/h output for residential heating and cooling loads
• 13.4 SEER2 efficiency rating meets current DOE minimum standards for packaged heat pumps
• R-454B refrigerant — a lower-GWP A2L refrigerant replacing R-410A in new equipment
• Single-stage operation for straightforward controls integration and simplified commissioning
• 208/230-volt, single-phase, 60 Hz electrical configuration for standard residential service
• All-in-one packaged cabinet reduces install complexity versus split-system configurations

Compatibility

Designed as an OEM packaged heat pump unit for residential applications requiring a self-contained heating and cooling solution with R-454B refrigerant.

Installation Notes

Installation must be performed by a licensed HVAC technician certified to handle A2L refrigerants, as R-454B has a mild flammability classification requiring specific safety protocols. Disconnect and lock out all electrical power before any service work on the unit. Follow NEC requirements for disconnect sizing, wire gauge, and overcurrent protection based on the unit nameplate data. Verify that the mounting pad or rooftop curb is level and rated for the unit weight before setting the cabinet.
