Oxbox J5HP5018A1000 Heat Pump Condenser 1.5 Ton 14.3 SEER2 R-454B Residential Split System

Product Description

The Oxbox J5HP5018A1000 is a 1.5-ton residential heat pump condenser unit rated at 14.3 SEER2 and designed to operate on R-454B refrigerant. It delivers both heating and cooling through a split-system configuration, pairing with a compatible air handler and TXV to form a complete system. Rated at 18,000 BTU/h, this unit suits smaller residential applications where efficiency and reliable year-round comfort are the primary requirements. The cabinet is constructed from painted galvanized steel for corrosion resistance. Licensed HVAC technicians install and commission this unit as the outdoor section of a residential split system.

This condenser is suited for residential split-system heat pump installations in smaller homes or zone applications where a 1.5-ton capacity is appropriate. Oxbox is a Trane brand, and this unit is designed to work within matched split-system configurations. The J5HP5018A1000 is part of the J5HP5 product family, which is available in a range of capacities. This unit has been listed in split-system and dual-fuel split-system configurations when paired with compatible air handlers and accessories.
