Two giants of wall-mounted heat pumps tested by the Quebec climate
In Quebec, where winters can be harsh and summers stifling, choosing a wall-mounted heat pump is not a decision to take lightly. Among the most reputable brands, Gree and Fujitsu stand out as two undisputed market leaders. But when it comes time to choose between the two for a HVAC installation in Montreal, Laval, Longueuil, the North Shore or the South Shore, which option proves to be the most efficient, durable, economical, and suited to our extreme climate conditions? At AirGreen, we have installed hundreds of systems from both brands, and this article draws on our field expertise to distinguish these two champions of energy performance.
The reality on the ground in Quebec: a crucial context
Before comparing the models, it is important to understand that the Quebec climate puts wall-mounted heat pumps to the test. With temperatures that can drop below -25°C in winter and rise above 30°C in summer, a device must demonstrate robustness, consistency, and high energy efficiency. Added to this are the challenges related to the subsidies offered by Hydro-Québec’s LogisVert program, which favor high-performance equipment.
Technical profile of Gree: reliability and innovation in cooling technology
Focus on the Gree Extreme and the Gree Sapphire
We have installed Gree Extreme and Gree Sapphire models in Sainte-Julie, Beaconsfield, Saint-Lambert, and Sainte-Marthe-sur-le-Lac, and the performance recorded in winter conditions is impressive. These Gree wall-mounted heat pumps operate efficiently down to -30°C, making them ideal for poorly insulated properties or those exposed to strong northern winds.
-
BTU power: from 9,000 to 24,000 BTU depending on the models.
-
High coefficient of performance (COP), even in freezing weather.
-
LogisVert eligibility: up to $2,172 in subsidies depending on the case.
-
Built-in Wi-Fi connectivity, ideal for remote management.
-
Low noise level (around 19 dB), perfect for bedrooms or home offices.
Customer case: Gree Extreme 18,000 BTU in Sainte-Julie
In a single-family home in Sainte-Julie, we installed a Gree Extreme 18,000 BTU to replace an old window air conditioner. Despite the particularly harsh winter of 2024, the unit maintained a stable indoor temperature without needing auxiliary heating. Result: a nearly 30% reduction in the electric bill.
Technical profile of Fujitsu: Japanese excellence and energy efficiency
Focus on the Fujitsu KZAH R-32
The Fujitsu KZAH R-32 is a high-end wall-mounted heat pump adopted by many customers on the South Shore and in Longueuil, especially in plexes and condos. This model stands out for its advanced Inverter technology, its eco-friendly R-32 refrigerant, and its consistent power down to -26°C.
-
BTU power: 9,000, 12,000, 15,000 BTU.
-
Energy class A+++.
-
Ultra-quiet compressor.
-
Compact and modern design, ideal for small rooms.
Case study: Fujitsu KZAH 12,000 BTU in Longueuil
We recently installed a Fujitsu KZAH 12,000 BTU in a downtown Longueuil condo near the metro. The client was looking for an efficient and aesthetic solution for a main room of 500 sq ft. Result: constant thermal comfort, minimal consumption, and no noise disturbance. All this with a $1,704 grant thanks to Hydro-Québec.

Our verdict: which brand to choose?
-
Do you live in a particularly cold or windy area like Oka, Mascouche, or Saint-Jérôme? The Gree Extrême or Sapphire is probably the best choice, thanks to its robustness and ability to operate down to -30°C.
-
Do you live in a condo or townhouse in Longueuil or Brossard and prioritize silence and aesthetics? The Fujitsu KZAH R-32 will offer you an ideal balance of efficiency, low consumption, and discretion.
