Best forThree rooms in a cold climate where the buyer is paying a contractor and wants a mainstream R-32 multi.

Overview

Gree's 30k R-32 multi is a three-port unit for a house that would otherwise get two 18k systems. Certified at 21.0 SEER2 and 10.0 HSPF2 (AHRI 215218915 for non-ducted heads, 13.6 EER2), it is rated to heat down to -22°F, and NEEP lists 27,000 BTU/h at 5°F against 30,000 at 47°F, a 90% hold. The package with two 9k and one 12k Livo head sells for about $5,058. Compared with Senville's 27k 3-zone kit at about $2,700, it costs nearly twice as much, but it also comes with a 7-year compressor warranty, Gree's wide choice of head types (including slim duct and cassette) and a bigger dealer base. It belongs on a shortlist for owners who want cold-climate output and a conventional contractor path.

  • 27,000 BTU/h at 5°F (NEEP)

  • Takes slim-duct and cassette heads too

Cold-weather output

At 5°F it still makes 90% of its rated heat, according to the certified NEEP listing for this pairing. Gree rates it to keep running down to -22°F.

Strengths and catches

Strengths

  • +NEEP lists 27,000 BTU/h at 5°F, 90% of the 47°F rating
  • +Precharged for 131 ft of lineset
  • +7-year compressor / 5-year parts with registration

Catches

  • −$5,058 package price is about twice a comparable Senville kit
  • −Needs a 230V circuit with a 35A maximum breaker

  • −R-32 heads only: older R-410A Livo heads will not connect

Questions buyers ask

Why would I choose a 3-zone Multi21+ over a 4-zone?+

Three rooms are served by the 30,000 BTU condenser, with heads of 9k, 9k and 12k. The 4-zone costs $6,942 against $5,058, so the 3-zone saves $1,884 if you do not need a fourth head.

How much of its heat does the 3-zone keep at 5°F?+

NEEP lists 30,000 BTU at 47°F and 27,000 BTU at 5°F, about 90%, with COP 2.07. Gree rates it to -22°F and it is ENERGY STAR cold climate listed.

Is R-32 a concern for install?+

R-32 is an A2L refrigerant, mildly flammable, so use an installer trained for it. Every indoor head must be an R-32 model. The condenser is precharged for 131 ft of lineset with 4.85 lb of R-32.

Can I install the 3-zone Multi21+ myself?+

No, it is a professional job with flared lines and evacuation. The warranty is 7-year compressor and 5-year parts with online registration.
