Oxbox J5HP5042A1000 Heat Pump Condenser 3.5 Ton 42000 Btu/h 14.3 SEER2 R-454B

Product Description

The Oxbox J5HP5042A1000 is a 3.5-ton single-stage heat pump condenser rated at 42,000 BTU/h with a 14.3 SEER2 efficiency rating. It operates on R-454B refrigerant, in compliance with DOE 2023 efficiency standards. Designed for split-system residential and light-commercial applications, this outdoor condensing unit handles both heating and cooling loads and is installed by licensed HVAC technicians as part of a matched split system. The unit runs on 208/230-volt single-phase power and is built for reliable operation across a wide range of outdoor ambient conditions, from cold-weather heating cycles to peak summer cooling demand.

This condenser is suited for residential split-system heat pump installations in mild to moderate climates where a single-stage unit covers typical load requirements. It pairs with a compatible indoor air handler and coil assembly to form a complete split system. The J5HP5042A1000 is part of the Oxbox J5HP5 series, which carries 14.3 SEER2 ratings and uses R-454B, a lower-GWP refrigerant that meets current EPA and DOE regulations. Typical installation scenarios include new construction and equipment replacement in residential homes and small commercial spaces.

Compatibility

Designed for use in split-system heat pump configurations requiring a 3.5-ton outdoor condensing unit. Compatible indoor air handlers and coil assemblies must be verified against the Oxbox J5HP5 series matching table for confirmed system efficiency ratings. No specific indoor unit model numbers were provided in available product data — consult the Oxbox J5HP5 installer matching table to confirm approved system combinations before installation.

Installation Notes

Installation must be performed by a licensed HVAC technician holding the appropriate EPA Section 608 certification for handling R-454B refrigerant. Before servicing or connecting refrigerant lines, de-energize the unit at the disconnect and follow lockout/tagout procedures. The refrigerant circuit must be leak-checked, evacuated, and charged per manufacturer specifications prior to startup. All electrical connections should conform to NEC requirements and local jurisdiction codes, and the unit must be mounted on a stable, level pad with adequate clearance on all sides per the installation manual.
