Napoleon
Canadian manufacturer of furnaces, air conditioners and cold-climate heat pumps alongside its hearth products — a growing presence in northern-market replacement work. Ductless reference: Identify the actual ductless indoor/outdoor models and obtain their documents from Napoleon or the supplying dealer. A Napoleon furnace manual does not describe the mini-split communication or inverter circuit.

Gas furnace
Covered in the simulatorThe indoor half of most split systems outside the Sun Belt: burners and heat exchanger below, the A-coil above, the 24V control system inside.
The control side — door switch, transformer, board, blower, low-voltage fuse — is fully modeled as the sim’s indoor cabinet, and the guided flow applies on cooling complaints. Combustion-side diagnostics are on the roadmap.

Split system A/C (straight cool)
Covered in the simulatorOutdoor condenser plus an indoor furnace-and-coil or air handler — the most common machine in single-family homes and garden-style multi-family.
The whole sim is built on this machine: every wing of the board and the guided no-cool flow apply directly.

Heat pump (split)
Lessons carry overA split system that also heats: one reversing valve decides which coil condenses. Everything a straight-cool split has, plus the O (or, on some brands, B) circuit and defrost.
The HEAT PUMP wing of the board works the reversing valve; the guided flow routes heat pumps to escalation until its playbook ships. The electrical side transfers one-for-one.

Ductless mini split
Reference for nowInverter-driven outdoor unit feeding one or more wall, ceiling or compact-ducted heads over a communicating line. The fastest-growing machine in both segments.
Inverter boards, communicating controls and electronic expansion valves — not the contactor-and-run-cap machine the board models, and dedicated mini-split tickets are on the roadmap. From the A2L start-up guide, the refrigerant handling, nitrogen and deep-vacuum discipline transfer; its charge-to-subcooling step does not — these machines charge by weight to the manufacturer’s line-length math, behind flares torqued to spec. On the call itself, flash codes and the manufacturer’s service data lead.
Tech support
The Copilot loads your Napoleon equipment details. Guided diagnostic coverage depends on the equipment type; ductless and monoblock systems currently use the reference library.
Model-number decoding here covers residential and multi-family split systems and package units, 5 tons and under — Napoleon equipment lives outside that scope, so the manufacturer’s literature leads on model specifics. The Copilot still loads the brand for a guided session.
