Cooling plus electric heat in one matched package: a 3.5 ton Oxbox air conditioner, a matched upflow air handler, and an 8 kW heat kit for a mid-size to larger home.
Key Features
Rated at 14.3 SEER2 (Oxbox's standard efficiency tier), this 3.5 ton Oxbox air conditioner split system is built for mid-size to larger homes. For heat, the 8 kW electric heat kit mounts inside the air handler and warms air through the same ducts that carry your cooling. 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.
- Scroll compressor: fewer moving parts than older piston designs, for steady, dependable operation.
- 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.
- Straightforward electrical: 24.9 A minimum circuit ampacity on the outdoor unit keeps breaker and wire sizing simple for a 3.5 ton install.
- 8 kW electric heat kit, included: covers your heating needs without a separate furnace, and arrives with the rest of the system.
- R-454B refrigerant: the low-GWP A2L refrigerant replacing R-410A in new residential equipment.

Common Questions
What comes in the box, and what do I still need?
You get the outdoor condenser, 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 thermostat. Professional installation by a licensed HVAC technician is required for refrigerant work.
How does this system heat?
This is an air conditioner, so heating comes from the included 8 kW electric heat strip inside the air handler. It's a simple, reliable setup for areas with short, mild winters. If you heat for much of the year, a heat pump system will usually cost less to run.
Is 3.5 tons the right size for my home?
3.5 tons is a common fit for mid-size to 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.
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.
