TOSOT Cosmo 12,000 BTU

Gree — TOSOT is its consumer-facing brand, sold through Amazon and online retailers instead of HVAC supply houses. Same factories and G-series compressor DNA as Gree-badged units, at a bread-and-butter $799 price with a 16 ft lineset in the box.

No — despite the consumer branding, it uses standard flare connections that require proper flaring and evacuation with a vacuum pump. Handy owners with the tools do install these, but most buyers should budget for a tech to make the connections and pull the vacuum.

The Cosmo comes in both 115V and 230V versions, and the model suffix is the only obvious difference — check it before wiring or buying. The 115V version can run on a standard-voltage dedicated circuit; the 230V version needs the usual two-pole circuit.

It's rated to -13°F, which covers shoulder seasons and moderate winters comfortably but rules out primary-heat duty in truly cold states. The 19 SEER2 / 8.5 HSPF2 efficiency also trails the class leaders, so high-runtime heating in an expensive-electricity area weakens its value case.

It's a simple 5-year whole-unit warranty — shorter than Senville's 10-year compressor coverage but with none of the split parts-vs-compressor fine print. Combined with the quiet 22-36 dB indoor range and included WiFi, it's a clean package for a bedroom or office.
