Under 800 sq. ft.: Go for Fujitsu or Gree models between 12,000 and 15,000 BTU.
-
Between 800 and 1,200 sq. ft.: Favor 18,000 BTU models like the Sharp ZU1 or the Zuba.
-
Over 1,200 sq. ft.: The Bosch IDS Premium or 24,000 BTU units are best suited.
Greater Montréal climate conditions
-
If you live in a more wind-exposed area (e.g.: Montérégie, Laurentians), choose a heat pump that can heat efficiently down to -30 °C.

For older or poorly insulated homes, choose a unit with high airflow and a strong seasonal performance factor.
