The Oxbox J5PH R-454B Series Package Units deliver reliable, high-efficiency heating & cooling in a single, self-contained system. Built by Trane Technologies as the value line, these Oxbox single-stage heat pump packaged units meet current federal 13.4 SEER2 minimums. The compressor, coils, blower, and controls sit in one outdoor cabinet with round duct connections ideal for manufactured housing, mobile homes, and tight residential or light commercial jobs where a split system is impractical.
Why homeowners love it
Saves indoor space — One outdoor cabinet and round ducts mean less indoor space, fewer refrigerant lines, and faster set on manufactured-home & mobile homes no separate air handler or furnace needed.
Lower Operating Cost than Older Packaged Units — 13.4 SEER2 rated with consistent single-stage performance.
Built for Outdoor Duty — Anti-rust painted galvanized steel cabinet, 500-hour salt spray tested.
Internal Protection — High/Low pressure, coil temperature, and power surge.
Easy to live with — Factory-charged and tested, front panels and a removable fan grille keep compressor, controls, coil, and blower reachable without pulling the unit.
A practical, dependable way to keep the house cool without a split-system install.
