Fujitsu in Montreal: the right series for your winter
With Fujitsu, every R-32 wall unit has its own cold-weather floor: -15 °C, -26 °C or -30 °C. Tell us the room and how you’ll use it, and we’ll show you the series, the size and the indicative LogisVert amount. Then we install it, anywhere in Montreal, Laval, Longueuil, the South Shore and the North Shore.
R-32How cold can each wall unit go?

Five R-32 wall units. The real difference is the cold.
Fujitsu ranks its own wall units on five levels. The higher you go, the lower the unit keeps heating, and the higher the LogisVert amount. Tap a series to see its sizes.
Orion XLTH
Heats down to -26 °C, with no protective shutdown in deep cold (“no temperature lockout”). Five sizes, from 9,000 to 24,000 BTU/h. It is the Fujitsu series that appears most in our published projects.

Three questions, one recommendation.
This tool replaces the old BTU calculator. It gives you an honest starting point; the free home visit confirms the size.
AirGreen rule of thumb: about 18,000 BTU/h per 1,000 sq ft, adjusted on site for insulation, windows and ceilings.
Orion XLTH+ · 12,000 BTU/h
Wall heat pump KTAP1, R-32
9,600 BTU/h at -8 °C ÷ 1,000 × $120 = $1,152
Why: main heat source: we pick the series that heats lowest for this size.
Same size, not the same heat at -15 °C.
ENERGY STAR certified values, at equal nominal size. Slide the thermometer down: the series that stop heating at that temperature turn grey.
At 12,000 BTU/h, the Orion XLTH delivers 16,600 BTU/h at -15 °C; the Altair 300, 8,200 BTU/h. And at -20 °C, only the Orion XLTH and the Orion XLTH+ are still heating.

In green: the best value in the row.
Two 12,000 BTU/h wall units: $435 or $1,200.
LogisVert pays according to the heat the unit delivers at -8 °C: $120 per 1,000 BTU/h if it is ENERGY STAR “cold climate”, $50 if it is standard ENERGY STAR. Pick a model to see the math.
Since November 26, 2025, only ENERGY STAR certified heat pumps qualify.
The outdoor unit must be at least 12,000 BTU/h Orion XLTH nominal in cooling. A 9,000 BTU/h unit gets nothing.
The grant never exceeds the purchase and installation cost, before taxes.
The application must be made no later than nine months after the unit is installed.
