Eight GREE multi-zone lines, two refrigerants. And two pairs with the same NEEP-certified capacities.

Each card is computed from the systems on this page: lowest point catalogued by NEEP, maximum capacity at −15 °C, room counts offered, ENERGY STAR designation and LogisVert amount from the list. Then the fact that sets the line apart.

LogisVert · Hydro-Québec

LogisVert pays for the system, not the number of rooms.

$120per 1,000 BTU/h of heat at −8 °C when the heat pump is ENERGY STAR “cold climate”.
$50per 1,000 BTU/h at −8 °C when it is ENERGY STAR only.
12,000 BTU/hMinimum nominal cooling capacity of the outdoor unit. The rule applies to the outdoor unit.
9 monthsTo apply after installation. Paid to the owner, capped at the pre-tax cost.

Per the LogisVert participant guide, version 1.10, September 15, 2026. A “mini-split” heat pump may include “one or more indoor units and one outdoor unit”: the amount is computed on the system, using the capacity ENERGY STAR lists at −8 °C (17 °F). The amounts below come from the product sheets and were compared with Hydro-Québec’s list dated Oct. 27, 2026; they remain indicative, and Hydro-Québec confirms them when you apply. Bonuses exist for multiple measures and for some rental buildings; the guide sets their conditions. Hydro-Québec LogisVert support: 1-833-396-1888, Monday to Friday, 8 a.m. to 8 p.m.

Questions

What people ask us about GREE multi-zone systems.

How many rooms can a GREE multi-zone heat pump serve?
It depends on the size of the outdoor unit. For the Free Match M R32, GREE Canada states: 18,000 BTU/h, 2 indoor units; 24,000, 2 to 3; 30,000 and 36,000, 2 to 4; 42,000, 2 to 5. The 2-room, 3-room, 4-room and 5-room pages group the systems by room count.
What is the difference between the Free Match M R32 and the MULTI R32?
The name, the model numbers and the documentation. The Free Match M R32 is published by GREE Canada and the Wolseley network, the MULTI R32 by GREE Comfort in the United States. On NEEP their certified heating capacities are identical; the only gap that affects the grant is at 18,000 BTU/h, explained on the MULTI R32 card.
Does a GREE multi-zone still heat at −30 °C?
Yes for four of the eight lines on this page, with NEEP figures to back it: the Free Match M R32, MULTI R32, M Series and Multi GEN2 have a published capacity at −30 °C. GREE Canada states a heating range down to −35 °C for the Free Match Extreme, but neither it nor the Multi+ Ultra is on NEEP any more as of Oct. 26, 2026. The Multi21+ stops earlier: its US brochure gives heating down to −5 °F, about −21 °C. The first-generation Free Match has no public document.
Can wall units, cassettes, consoles and ducted units share one outdoor unit?
Yes. For the Free Match M R32, GREE Canada publishes the list of indoor units compatible with each size: wall units, console, 1-way cassette, 8-way cassette and high-static slim duct. The system then carries a different AHRI number: “non-ducted”, “ducted” or “mixed”. For the 42,000, for example: 214931590, 214931596 and 214931600.
How much does LogisVert pay for a multi-zone?
Hydro-Québec pays per system, not per room: $120 per 1,000 BTU/h of heat at −8 °C if it is ENERGY STAR “cold climate”, $50 if it is ENERGY STAR only, with an outdoor unit of at least 12,000 BTU/h in cooling. The highest amount on this page is $5,340; the first-generation Free Match, the Multi21+ and the Multi+ Ultra are not on the list of Oct. 27, 2026, and of the Free Match Extreme only the 18,000 remains.
What GREE warranty applies to a multi-zone?
It depends on the line and the network that distributes it. For the Wolseley-network Free Match M R32, brochure X610068B states: “10 year standard warranty. Additional 2 year extended warranty with Wolseley when product is registered and/or proof of installation.” Per Dettson document X42020.1_A, those 2 years must be registered within 90 days of installation. The lines documented by GREE Comfort (MULTI R32, Multi GEN2, Multi+ Ultra, Multi21+) only have US terms published. Ask us for the manufacturer’s written warranty for the model you choose.
Do I need a special electrical panel?
One 208–230 V circuit powers the whole system, indoor units included. Per GREE Canada, the minimum circuit ampacity (MCA) runs from 18.5 A (18,000 BTU/h) to 30 A (42,000 BTU/h), with maximum overcurrent protection of 20 to 45 A. The Wolseley-network brochure gives other values for some sizes: your unit’s nameplate decides. Our RBQ licence 16 covers the electrical work.
