Discontinued. Gree replaced it with the Gree Multi21+ R-32 18,000 BTU 2-Zone. Leftover stock still turns up; the specs below are for this model.
Best forTwo-room installs in moderate climates wanting name-OEM build quality without Mitsubishi pricing.
Gree is the world's biggest AC manufacturer — it builds compressors half this list depends on — and the Multi Gen2 is the R-410A package that Gree has since replaced with the R-32 Multi21+. This 9k+9k Livo package lands between the bargain imports and the Japanese brands: 21 SEER2, 10 HSPF2, G10 inverter compressor, and heads as quiet as 26 dB. The usual multi-zone caveats apply: one condenser equals one point of failure for two rooms, and the minimum modulation floor of an 18k outdoor unit oversizes any single 9k call, so expect more cycling than two singles would produce. The Gen2's rated heating floor of -5°F is workable in the mid-Atlantic and mild Midwest but short of the -22°F cold-climate claims Senville makes — Gree's own low-ambient answer is the pricier Multi Ultra series. This R-410A condenser is leftover stock, so confirm availability before you get a quote built around it.
At 5°F it still makes 76% of its rated heat, according to the certified NEEP listing for this pairing. Gree rates it to keep running down to -5°F.
Pairing: MULTI18HP230V1EO with non-ducted heads. From NEEP's ccASHP list; a different head or condenser posts different numbers.
Not quite — the ~$2,400 typically covers the condenser and two Livo Gen4 heads, but line sets are usually sold separately, so budget another $150-300. Check the listing contents carefully; this catches a lot of buyers comparing against kits like Senville's that include everything.
Gree is the world's largest AC manufacturer and builds its own G10 inverter compressors — it's the OEM behind several other badges on the market, which also means unusually wide US parts availability for a non-Japanese brand. The hardware pedigree is not the risk; the online-channel warranty is the thing to scrutinize.
Bought online, you get only a 5-year limited parts warranty; longer coverage requires purchase and installation through a registered Gree dealer. If you're hiring a pro anyway, ask whether they can source it through Gree's channel to unlock the better terms.
No — the rated heating floor is -5°F, which rules out serious cold-climate duty. It's aimed at two-room installs in moderate climates, where its 21 SEER2 / 10 HSPF2 and the whisper-quiet Livo heads make it a strong mid-market pick between the bargain imports and Mitsubishi pricing.
No — the condenser supports mixed head types including ceiling cassettes and slim-duct units. Just respect Gree's connected-capacity table: the 18k condenser is happiest with 15k-21k of connected indoor capacity, and note that Gree has moved this package to R-32, so R-410A configurations are leftover stock.
