Installation of a FUJITSU ORION XLTH KZAH R-32 12,000 BTU wall-mounted heat pump in Saint-Bruno
Professional installation of a FUJITSU ORION XLTH 12,000 BTU heat pump in Saint-Bruno. Optimal comfort, high energy efficiency, and an ideal HVAC solution for Montreal and the South Shore.

In summer, the outdoor unit rejects the house's heat outside.
Generic illustration of this type of installation, not a survey of this job site. Tap a number.
Mounted level on a wall plate, high enough for the air to reach the whole room, with enough space around it to slide the filters out easily.
The refrigerant lines, the communication cable and the drain go through the wall in a single opening, sealed against water, cold air and insects.
Two insulated copper pipes connect the two units. Outside, a line cover can protect them from sun, knocks and weather.
A shut-off switch near the outdoor unit isolates it safely for service. It must stay accessible at all times.
The compressor and the fan. In heating mode it captures heat from the outdoor air, even in winter, and moves it inside.
On the ground or on the wall, it keeps the unit above accumulated snow. The unit stays clear and defrost water can drain away.
The fan needs to blow freely. Storage, a fence or a wall too close, and efficiency drops while noise goes up.
Strategic HVAC Installation for Four-Season Comfort on the South Shore
In Saint-Bruno, on Montreal's South Shore, we recently completed the installation of a FUJITSU ORION XLTH 12,000 BTU wall-mounted heat pump in a modern single-family home. The project had a clear goal: to provide efficient heating in winter and effective air conditioning in summer, while reducing overall energy consumption.
From our first visit, we observed that the existing system — primarily based on electric baseboards — no longer met the owner's expectations. Temperature fluctuations, high electricity costs, and the lack of central air conditioning made the space uncomfortable, especially during extreme periods.
Our solution: an optimized wall-mounted HVAC installation, centered on a unit known for its performance in Quebec's cold climate.
A Thoughtful Choice: Why the FUJITSU ORION XLTH 12,000 BTU?
Performance Adapted to Saint-Bruno's Winters
The FUJITSU ORION XLTH KZAH R-32 | 12,000 BTU model is specifically designed for the rigorous conditions of Greater Montreal, Laval, Longueuil, the North Shore, and the South Shore. It offers:
- Efficient heating down to -26°C
- Stable heating capacity even in very cold weather
- Inverter technology for intelligent modulation
In this Saint-Bruno project, this capacity was essential, as the house features an open-concept area with a standard ceiling, requiring uniform heat distribution.
Energy Efficiency and Subsidy
This system is ENERGY STAR® (Cold Climate) certified and eligible for a LogisVert subsidy of $1,200, making it a wise investment.
Its technical performance includes:
- SEER2: 30.5
- HSPF2: 12.7
- EER2: 16.0
- More environmentally friendly R-32 refrigerant
Result: a tangible reduction in energy costs, from the very first season of use.
Site Analysis and Optimal Unit Positioning
Indoor Installation: Precision and Aesthetics
Observing the project image, we notice a wall-mounted installation positioned high up, near the ceiling, which is a strategic decision. This allows for:
- Better distribution of warm air in winter
- Effective diffusion of cool air in summer
- Optimization of overall performance
We chose a central wall in the main room, ensuring maximum coverage without obstruction.
Key technical points:
- Perfectly horizontal alignment
- Respected clearance around the unit
- Easy access for maintenance
Challenges Encountered
Even though the installation appears simple visually, several elements required our expertise:
- Discreet routing of plumbing (1/4 – 3/8)
- Aesthetic management of conduits
- Minimizing interior visual impact
We used a professional pipe cover, matching the wall color, for a clean and durable result.
Outdoor Installation: Durability in Quebec's Climate
The outdoor unit was installed on an elevated wall bracket, which allows for:
- Avoiding snow accumulation
- Facilitating drainage
- Extending the equipment's lifespan
Our Outdoor Installation Criteria
At AirGreen, every HVAC installation in Montreal and on the South Shore follows rigorous standards:
- Orientation protected against prevailing winds
- Respected regulatory distance
- Access for future maintenance
In this specific case in Saint-Bruno, we also considered the residential environment to limit noise pollution.
Silent and Smart Comfort
Exceptional Sound Level
The FUJITSU ORION XLTH is particularly appreciated for its quiet operation:
- 23 dB(A) indoors (silent mode)
- 47 dB(A) outdoors
In this house, this allowed for continuous use, even at night, without disturbance.
Integrated Wi-Fi Connectivity
The client now benefits from complete remote control:
- Temperature adjustment before returning home
- Scheduled programming
- Energy optimization
This feature has become essential for modern homeowners, especially in cities like Longueuil, Laval, and Montreal.
Concrete Results After Installation
A few weeks after commissioning, client feedback was very positive:
- Stable temperature throughout the room
- Significant reduction in heating costs
- Increased comfort during cold days
The Inverter mode eliminated the typical fluctuations of traditional systems.
Practical Tips for Maximizing Your Heat Pump
Recommended Maintenance
To ensure the performance of your FUJITSU wall-mounted heat pump, we recommend:
- Cleaning filters every 4 to 6 weeks
- Annual inspection by a professional
- Clearing the outdoor unit in winter

And at your place?
Two quick checks with real numbers: what heat costs, and what your current heaters add up to in BTU/h.
Baseboards and electric furnaces turn 1 kWh of electricity into 1 kWh of heat. A heat pump delivers more: that is its COP. At Hydro-Québec’s rate D (11.142¢/kWh above 40 kWh a day, since 1 April 2026):
Hydro-Québec: a heat pump can be up to three times more efficient than baseboards for heating in the colder months.
Estimate per kWh of heat, at the chosen temperature, using the certified COP from the product page. Taxes, access charge and backup heat not included.
Conversion: 1 W = 3.412 BTU/h. An indication, not a load calculation: baseboards and furnaces are often stronger than the real need, and they can stay as backup. AirGreen confirms the capacity on site.
