Gree Mini Split AC Units: Sapphire, LIVO+ and Multi-Zone Compared

Best for
Large rooms and open-plan spaces

The Gree R32 24,000 BTU 23 SEER system is the biggest single-zone option here and the one to look at for large rooms or houses, which is exactly how the listing classifies it. You get an outdoor condenser, an indoor wall-mounted air handler and a wireless remote. The 1/4 by 5/8 inch line set is required but not included, so budget for it with your installer.

It uses Gree’s G10 inverter, which ramps the compressor up and down instead of slamming on and off. That is what keeps room temperature steady and outdoor noise lower, and it is why inverter mini splits feel so much calmer during a long session than older fixed-speed units. Built-in Wi-Fi works with the GREE+ app, Google Home and Alexa. The listing notes 24,000 BTU of cooling and heating, a 23 SEER rating and R32 refrigerant. If your space is a single mid-size room, the 18,000 BTU version below is a better fit, since oversizing makes a mini split short-cycle and dehumidify poorly.

• 24,000 BTU cooling and heating, 23 SEER
• Built-in Wi-Fi with GREE+, Alexa and Google Home
• 5-year parts and 7-year compressor warranty with licensed install

Best for
Mid-size rooms in harsh climates

The Gree R32 18,000 BTU 23 SEER heat pump shares the same G10 inverter, R32 refrigerant, built-in Wi-Fi and warranty terms as its bigger sibling, with a 13 EER rating spelled out on top of the 23 SEER. Its standout detail is the operating range: the listing says it cools from -22 to 122°F and heats from -22 to 86°F, so it is built for regions that swing hard between seasons.

The description adds Energy Star status, 7 fan speeds plus Turbo, vibration-reducing engineering and power surge protection. It also warns that the seller may ship a newer or comparable upgraded product depending on inventory, so check model numbers on delivery. This is the balanced choice for a sizable bonus room or a converted garage setup. For a smaller dedicated room, the Sapphire 9,000 BTU delivers far higher efficiency.

• 23 SEER, 13 EER, Energy Star
• Cooling and heating down to -22°F
• 7 fan speeds plus Turbo
• Line set 1/4 by 5/8 inch not included

Best for
Efficiency-first game rooms and offices

The Gree R32 9,000 BTU 38 SEER Sapphire is the efficiency flagship of this group. The listing quotes up to 38 SEER in cooling, 15.0 HSPF in heating and 16.7 EER, with ULTRA Heating technology rated to keep working at -22°F. It is sized for rooms of 300 to 500 square feet, which is exactly the footprint of most dedicated gaming rooms, home offices and small media rooms.

Gree describes it as quiet and unobtrusive, and the spec sheet adds a UV filter, universal Wi-Fi through the Gree+ app and a variable-speed two-stage compressor with low voltage start-up. The line set here is 1/4 by 1/2 inch and is not included. If you are building a room around a PC rig or projector and want the lowest running cost per hour of cooling, this is the pick. It simply cannot cover a large open space, where the 24,000 BTU model takes over. For a smaller temporary fix instead of a permanent install, compare it with an 8,000 BTU portable AC unit.

• Up to 38 SEER and 15.0 HSPF
• ULTRA Heating down to -22°F
• UV filter and built-in Wi-Fi
• Sized for 300-500 square feet

Best for
Two rooms on one condenser

The Gree 18,000 BTU Multi21+ Dual-Zone Wall system solves a different problem: two rooms, one outdoor condenser. The title lists SEER 22 and a 9 plus 12 configuration, meaning the 18,000 BTU total is split across two indoor heads, and Gree notes it heats and cools both zones without distribution boxes. It uses the G10 inverter-driven compressor but runs on R410A refrigerant rather than R32.

The listing is inconsistent on connectivity. The features say Wi-Fi is available through a field-installed kit sold separately, while the description says the system comes with built-in Wi-Fi. Treat Wi-Fi as an add-on until you confirm otherwise. You will also need two line sets, 1/4 by 3/8 inch and 1/4 by 1/2 inch, neither included. Choose it if you want a game room and a bedroom handled together; choose a single-zone model if only one room needs conditioning.

• Two zones from one condenser, no distribution boxes
• SEER 22 with G10 inverter
• Two separate line sets required

Best for
Single rooms with simpler needs

The Gree R32 LIVO+ 18,000 BTU Wall heat pump is the straightforward single-room model. It shares the G10 inverter and R32 refrigerant but is built around 16 SEER heat pump technology, the lowest efficiency rating in this group. The operating range is narrower too: cooling from 0 to 115°F and heating from -4 to 75°F.

Where it earns its place is features for everyday comfort. The listing mentions multiple fan speeds, sleep mode, dehumidification, intelligent preheating, low voltage start-up, a programmable timer, a Blue Fin condenser coil, self diagnostics and a remote that senses the temperature around it to adjust airflow. An optional wired controller is available. Wi-Fi requires the separate WSBEC02 kit. It suits a room in a milder climate; for cold regions, the 23 SEER 18,000 BTU model is the stronger heat pump.

• 16 SEER with G10 inverter
• Sleep, dry and intelligent preheating modes
• Wi-Fi via optional WSBEC02 kit
