GREE dual-zone · 2 rooms · Updated Oct. 27, 2026

GREE dual-zone heat pumps. Two rooms heated by one outdoor unit, which shares its capacity according to tables GREE publishes.

38 GREE two-room systems, from 18,000 to 42,000 BTU/h, in 8 lines. For two closed rooms: two bedrooms, a bedroom and an office, or a basement living room and bedroom. Three figures decide: the heat each room receives, the line-set length and the LogisVert amount.

Dual-zone lines

Eight lines take two rooms. Here is what sets each apart.

Each card counts only the two-room systems on this page: lowest point catalogued by NEEP, maximum capacities at −15 °C and −8 °C, ENERGY STAR designation and LogisVert amount from the list.

Dual-zone or two wall units?

Two rooms: one outdoor unit or two?

Both work, and neither wins every time. Here is what changes.

One dual-zone

  • 1 outdoor unit, 1 circuitBoth indoor units are powered by the outdoor unit (Free Match M R32).
  • Shared capacityThe unit splits its capacity between the two indoor units; the “Rooms” tool shows each one’s share.
  • LogisVert: one amountThe system counts once; the figures are compared further down.
  • A single point of failureIf the outdoor unit stops, both rooms stop.

Two separate wall units

  • 2 outdoor units, 2 circuitsTwo spots outside, two connections.
  • Each room has full capacityNothing is shared between the two rooms.
  • LogisVert: one amount per wall unitOnly if its outdoor unit reaches 12,000 BTU/h of cooling.
  • IndependentA failure stops only one room.
See the GREE wall units

12,000 BTU/h rule: LogisVert participant guide, version 1.10, Sept. 15, 2026, Appendix I.

The two-room selector

The two-room systems, sorted by maximum heat at −15 °C.

Filter by capacity, then sort. For two small rooms, look at the 18,000 first; for two large cold rooms, compare the heat at −15 °C of the 24,000 and up.

Sort by

Heat: maximum capacities NEEP publishes for the outdoor unit with the indoor-unit combination certified under its AHRI number. With two units, each room receives at most what the manufacturer’s table gives for their sizes: see the “Rooms” tool. LogisVert: the amount on Hydro-Québec’s list for the same AHRI number.

Questions

What people ask us about the GREE dual-zone.

Which GREE heat pump for two rooms?
Every line on this page has an outdoor unit for two indoor units. The size is chosen on the heat each room needs, calculated at your home: GREE Canada’s table shows what each room receives depending on the outdoor unit (the “Rooms” tool). If a third room is possible later, we start from a size that accepts it.
Two separate wall units or one dual-zone?
Both work. For LogisVert, a dual-zone counts as one system and two wall units as two: two 9,000 BTU/h wall units get nothing, two 12,000 units can earn more than an 18,000 dual-zone. For comfort, two wall units stay independent; a dual-zone has only one unit outside. We compare both at your home, with figures.
Which indoor unit sizes on an 18,000 BTU/h?
GREE Canada lists six combinations for the 18,000 Free Match M R32: 5+5, 5+7, 7+7, 9+9, 9+12 and 12+12 (thousands of BTU/h). A note also allows a 5,000 or 7,000 wall unit in place of the 9,000. With 12+12 the unit shares its 18,000 BTU/h: each room gets 9,000 BTU/h of heating per the table.
Can I add a third room later?
On the Free Match M R32, not with the 18,000 BTU/h: GREE Canada limits it to two indoor units. The 24,000 accepts up to three; the 30,000 and 36,000, up to four; the 42,000, up to five. The other lines have their own limits, shown on their product sheets.
Can a dual-zone mix a ducted unit and a wall unit?
Yes. The system then carries the “mixed” AHRI number: 214931592 for the 18,000 Free Match M R32, certified at 19.0 SEER2 and 9.0 HSPF2 per NEEP and ENERGY STAR, versus 21.0 and 10.0 with two non-ducted units. GREE Canada’s brochure prints 9.3 HSPF2: we use the certified value.
How much line set for two rooms?
On the 18,000 Free Match M R32, GREE Canada allows 40 m in total, 20 m to the farthest indoor unit and 15 m of height difference. The first 10 metres are factory-charged; beyond that, 20 g of R-32 is added per metre. The “Line sets” tool does the math.
