Air-Con
Distinguish domestic and export-only models; voltage, frequency and service parts depend on the exact version. Use Air-Con’s documentation rather than a generic mini-split wiring diagram.

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 Air-Con 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 — Air-Con equipment lives outside that scope, so the manufacturer’s literature leads on model specifics. The Copilot still loads the brand for a guided session.
