Outdoor Sound Rating
One outdoor unit for summer and winter. This Oxbox 3 ton heat pump system ships with its matched upflow air handler and an 8 kW heat kit, ready to heat and cool mid-size single-family homes.
Key Features
At 3 tons and 14.3 SEER2, this Oxbox heat pump system sits in Oxbox's standard efficiency tier. The heat pump handles both heating and cooling, and the 8 kW heat kit in the air handler steps in when outdoor temperatures drop or the system goes through defrost. This matchup uses the J5AH4P36A1B00AA air handler, an upflow unit with a 1/3 HP blower motor. It uses R-454B refrigerant on standard 208/230V single-phase power and is approved for both DOE North and South regions.
- One system, two seasons: the heat pump reverses refrigerant flow to heat your home in winter and cool it in summer.
- Straightforward electrical: 21.5 A minimum circuit ampacity on the outdoor unit keeps breaker and wire sizing simple for a 3 ton install.
- Upflow air handler with built-in evaporator coil: matched to this outdoor unit, with a 1/3 HP blower motor moving air through your ductwork.
- R-454B refrigerant: the low-GWP A2L refrigerant replacing R-410A in new residential equipment.
- Scroll compressor: a proven compressor design known for smooth, steady operation and long service life.
- 8 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.

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 8 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 8 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 3 tons the right size for my home?
3 tons is a common fit for mid-size single-family 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.
14.3 or 15.2 SEER2: which should I choose?
Both meet current efficiency requirements. The 15.2 SEER2 systems cost a bit more up front and use less electricity to cool, so they make the most sense where the system runs much of the year. The 14.3 SEER2 systems keep the purchase price lower. This system is the 14.3 SEER2 version.
