Straightforward comfort for a mid-size to larger home: a 3.5 ton Oxbox air conditioner, a matched upflow air handler, and an 8 kW electric heat kit, all shipped together.

Key Features

This Oxbox 3.5 ton air conditioner split system is rated at 14.3 SEER2, Oxbox's standard efficiency tier. Heating comes from the included 8 kW electric heat strip inside the air handler, a simple setup for areas with short, mild winters. This matchup uses the J5AH5E36A1B00AA air handler, an upflow unit with a 1/2 HP blower motor. At this capacity it's a common choice for mid-size to larger homes. It uses R-454B refrigerant on standard 208/230V single-phase power and is approved for both DOE North and South regions.

  • Scroll compressor: fewer moving parts than older piston designs, for steady, dependable operation.
  • 8 kW electric heat kit, included: gives you dependable heat from the same air handler, ideal where winters are short and mild.
  • 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.
  • R-454B refrigerant: the low-GWP A2L refrigerant replacing R-410A in new residential equipment.
  • Straightforward electrical: 24.9 A minimum circuit ampacity on the outdoor unit keeps breaker and wire sizing simple for a 3.5 ton install.

Common Questions

What else do I need for installation?
Plan on a copper line set sized for your run, a condenser pad, an outdoor disconnect, electrical wiring, and a thermostat. Refrigerant work must be done by a licensed HVAC technician.
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.
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.
