One outdoor unit for summer and winter. This Oxbox 4 ton heat pump system ships with its matched upflow air handler and a 10 kW heat kit, ready to heat and cool larger homes.
Key Features
Rated at 14.3 SEER2 (Oxbox's standard efficiency tier), this 4 ton Oxbox heat pump split system is built for larger homes. In summer it cools; in winter the same outdoor unit reverses to pull heat in from outside air, with the included 10 kW heat strip standing by for the coldest mornings, defrost cycles, or emergency heat. This matchup uses the J5AH4P48A1C00AA air handler, an upflow unit with a 1/2 HP blower motor. Everything runs on R-454B refrigerant and 208/230V single-phase power, and it's approved for installation in both the DOE North and South regions.
- Heating and cooling from one outdoor unit: the reversing heat pump replaces a separate furnace in most mild-winter climates, so there's one system to service instead of two.
- 80 dB sound rating: the outdoor unit's published sound level, useful for planning placement near bedrooms, patios, or neighbors.
- 10 kW auxiliary heat kit, included: installs inside the air handler and steps in automatically when the heat pump needs help or during defrost. No separate purchase to track down.
- Scroll compressor: fewer moving parts than older piston designs, for steady, dependable operation.
- R-454B refrigerant: the low-GWP A2L refrigerant replacing R-410A in new residential equipment.
- Upflow air handler with built-in evaporator coil: matched to this outdoor unit, with a 1/2 HP blower motor moving air through your ductwork.

Common Questions
What comes in the box, and what do I still need?
You get the outdoor heat pump, the indoor air handler, and the 10 kW heat kit. You'll still need a copper line set sized for your run, a condenser pad, an outdoor disconnect, electrical wiring, and a heat-pump-compatible thermostat. Professional installation by a licensed HVAC technician is required for refrigerant work.
Why does a heat pump need a heat kit?
A heat pump heats by moving warmth from outdoor air into your home, and it gets less efficient as temperatures drop. The 10 kW heat strip covers that gap on the coldest days, keeps air warm during defrost cycles, and gives you emergency heat if the outdoor unit ever needs service.
Is 4 tons the right size for my home?
4 tons is a common fit for larger homes, but square footage alone isn't a reliable guide. Insulation, windows, sun exposure, and ductwork all matter. A Manual J load calculation from your installer is the best way to confirm sizing before you buy.
How do I get the 10-year parts warranty?
Coverage is 5 years on parts as standard. Register the system with Oxbox after installation to extend parts coverage to 10 years.
