Oxbox J5AC5042A1000 Air Conditioner Condenser 3.5 Ton 42000 Btu/h 14.3 SEER2 R-454B Residential Split System

Product Description

The Oxbox J5AC5042A1000 is a 3.5-ton residential split-system air conditioner condenser rated at 42,000 BTU/h with a 14.3 SEER2 efficiency rating. It operates on R-454B refrigerant, a lower global-warming-potential (GWP) alternative that meets current regulatory requirements for new residential cooling equipment. The unit features a scroll compressor and is designed for single-phase power. Cabinet construction uses painted galvanized steel for corrosion resistance. The evaporator coil includes a hydrophilic coating to improve moisture drainage and heat transfer performance. Licensed HVAC technicians install this unit as the outdoor section of a ducted split-system cooling or gas-electric combination system.

The J5AC5042A1000 is suited for residential ducted split-system applications requiring 3.5-ton nominal cooling capacity. It is part of the Oxbox J5AC5 series, which spans 1.5 to 5.0 ton models. The unit is designed to pair with a compatible indoor air handler or gas furnace in a matched-system configuration. Sound output is rated at 76 dB. Cabinet dimensions are 28 inches wide by 28 inches deep by 33.19 inches tall. This condenser is marketed under the Oxbox brand, which is a Trane-affiliated product line offering value-tier residential HVAC equipment.

Compatibility

Part of the Oxbox J5AC5 series. The J5AC5042A1000 outdoor condensing unit is compatible with the Oxbox J801V120DM5SEB gas furnace in a gas-electric split-system configuration. Match with a compatible Oxbox or Trane-affiliated indoor coil for a fully rated system. Consult the AHRI directory or manufacturer matchup tool to confirm rated system combinations before installation.

Installation Notes

Installation must be performed by a licensed HVAC technician certified to handle A2L refrigerants, as R-454B is a mildly flammable refrigerant class requiring specific handling procedures and equipment. Power down the disconnect and confirm zero voltage before making any electrical connections. Follow local mechanical codes and manufacturer clearance requirements for pad placement, refrigerant line sizing, and condensate routing. Do not commission the system without verifying proper refrigerant charge using manufacturer-specified procedures and calibrated equipment.
