Gree
One of the world’s largest air-conditioner manufacturers: Flexx and Vireo ductless lines, PTACs — and the OEM factory behind several familiar North American badges.
What they make
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.
PTAC / PTHP
Lessons carry overThe under-window wall-sleeve unit in hotels, apartments and senior living — cooling with electric heat (PTAC) or a heat pump (PTHP), each serving one room.
Run capacitors, fan motors, plugged drains and matted coils — the RUNS-BUT-WON’T-COOL and GAUGES wings teach the same failures; dedicated PTAC tickets are on the roadmap. Respect the supply: many commercial buildings feed PTACs 265V, which is not the 115V habit you brought from residential.

Tech support
Tech support here is the guided Copilot with your Gree info already loaded — one question at a time, evidence before parts, and everything you enter rides into the service report.
Model-number decoding here covers residential and multi-family split systems and package units, 5 tons and under — Gree equipment lives outside that scope, so the manufacturer’s literature leads on model specifics. The Copilot still loads the brand for a guided session.
