Providing the best year-round thermal comfort to Quebec homeowners, while accounting for the province’s climate realities, is a real challenge for HVAC installers. At AirGreen, we’ve installed hundreds of wall-mounted heat pumps across Montreal, Laval, Longueuil, the North Shore and the South Shore, and two models come up time and time again in conversations with our customers: the Bosch IDS and the Fujitsu Halcyon. Both are very popular in the residential market, and each offers unique features that deserve a detailed breakdown to help consumers make an informed decision.
A Crucial Comparison for Quebec’s Climate
Quebec experiences harsh winters, increasingly hot summers, and a growing demand for energy efficiency. The goal of a wall-mounted heat pump is to deliver optimal year-round comfort while reducing energy consumption. That’s the context in which we compare the Bosch IDS Premium R-454B and the Fujitsu Halcyon KZAH R-32, two systems well-suited for typical single-family homes in the province.

AirGreen Case Studies: Real-Life Installations
Installation of a Bosch IDS 18,000 BTU in Saint-Bruno
In a single-family home in Saint-Bruno-de-Montarville, our technicians installed a Bosch IDS Premium 18,000 BTU to replace an old oil heating system. The challenges included a tight space for the outdoor unit and an aging electrical system. We:
-
Reinforced the existing 240V electrical supply
-
Customized the wall bracket to optimize airflow
-
Performed a finely tuned startup for the inverter compressor
Result: consistent performance down to -28 °C in January, and a 35% reduction in winter energy bills.
Installation of a Fujitsu Halcyon 12,000 BTU in Laval
In a duplex in Laval, we installed a Fujitsu Halcyon R-32 12,000 BTU in the upper unit. The goal: quiet cooling in summer and reliable auxiliary heating in winter. The owner wanted a discreet, energy-efficient solution. We:
-
Placed the indoor unit above a door for optimal airflow
-
Used a low-profile wall exit to the backyard-facing outdoor unit
-
Ran airflow and temperature tests in each room
Result: perfect comfort, zero noticeable noise even at night, and a 28% drop in electricity use.

What to Consider to Make the Right Choice
For larger homes or higher heating demands:
The Bosch IDS Premium is more suitable thanks to its steady heating capacity down to -30 °C, sturdy build, and reliable performance even during extreme cold.
For small spaces, apartments, or duplexes:
The Fujitsu Halcyon excels with its whisper-quiet operation, compact design, and very high energy efficiency. Ideal for those looking for a discreet and effective unit.
