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