An HVAC System Optimized for a Residential Home in Lorraine
In Lorraine, on the North Shore, we recently completed a full HVAC installation of a FUJITSU Aquila XLTH R32 24,000 BTU dual-zone heat pump, perfectly suited to Quebec's climatic conditions. This project concretely illustrates our rigorous approach at AirGreen: precise needs analysis, impeccable technical execution, and particular attention to visible... and invisible details.
The property featured a typical configuration for homes in the region: brick exterior wall, exposed concrete foundation, narrow side access, and a semi-basement with a window. These elements directly influence the installation strategy, particularly the positioning of the outdoor unit and the routing of the refrigerant lines.
A FUJITSU System Designed to Withstand Quebec Winters
Exceptional Thermal Performance Down to -26 °C
The FUJITSU Aquila XLTH heat pump installed in Lorraine stands out for its ability to maintain reliable heating performance down to -26 °C, making it an ideal solution for Greater Montreal, Laval, and the North Shore.
Technical specifications of the installed system:
- Total Capacity: 24,000 BTU
- Dual-zone configuration: two independent wall-mounted units
- Refrigerant: R-32 (more ecological and efficient)
- SEER2: 23.5 (high cooling efficiency)
- HSPF2: 11.5 (excellent heating performance)
- Outdoor sound level: approximately 52 dB(A)
- ENERGY STAR® certified (cold climate)
This system allows occupants to individually control the temperature in two distinct zones of the house, thereby improving comfort and reducing energy consumption.
LogisVert Subsidy Available
This installation is eligible for a LogisVert subsidy of approximately $1,944, a significant financial advantage for homeowners wishing to modernize their heating and air conditioning system in Montreal, Longueuil, or on the South Shore.
Technical Challenges Encountered on Site
Installation on Foundation Wall with Space Constraint
The project image clearly shows a common challenge: installing the outdoor unit on a wall bracket attached to a concrete foundation, just above a basement window.
We had to:
- Install a robust and perfectly level wall mount
- Maintain a safe minimum distance above the window
- Ensure optimal condensation drainage
- Maintain easy access for future maintenance
Precise positioning of the unit is essential to avoid vibrations, reduce noise, and maximize the system's lifespan.
Refrigerant Line Routing on the Facade
Another visible element is the horizontal aluminum pipe cover installed along the wall. This component is not only aesthetic: it protects the lines from weathering and temperature variations.
We carefully:
- Aligned the pipe cover with the existing masonry
- Minimized penetrations in the structure
- Optimized the slope for drainage
This type of finish is particularly appreciated in residential areas of Lorraine, Laval, and Boucherville, where the exterior appearance of the house is important.
Management of Restricted Side Space
The narrow passage between the house and the fence presented a logistical challenge. Our technicians had to work in a limited space while respecting safety standards and recommended distances for outdoor unit ventilation.
An Installation Completed in a Single Day
Thanks to our experience in multi-zone heat pump installation, we completed this project in a single day, including:
- Wall mount installation
- FUJITSU outdoor unit mounting
- Refrigerant line routing
- Installation of two indoor wall-mounted units
- 220V electrical connection
- Vacuuming and leak testing
- Full system commissioning
The client was able to immediately benefit from optimal thermal comfort, without prolonged interruption of their activities.
Why Choose a Dual-Zone Heat Pump in Lorraine?
Personalized Comfort in Each Room
A dual-zone heat pump allows two spaces to be heated or cooled independently. In this project:
- One unit serves the main living room
- The other covers an upstairs bedroom
This allows for:
- Avoiding energy loss
- Adapting temperature according to occupancy
- Improving overall comfort
Reduced Energy Costs
Thanks to INVERTER technology and the high efficiency of the FUJITSU system, energy bill savings are significant, especially in winter.
Mistakes Avoided During This Installation
At AirGreen, we regularly correct poorly executed installations. In this project in Lorraine, we took care to avoid several common mistakes:
Incorrect Outdoor Unit Positioning
Installation that is too low or too close to the ground can lead to:
- Snow accumulation
- Poor air circulation
- Reduced performance
We therefore installed the unit on an elevated wall bracket, ideal for Quebec winters.
Excessive Line Length
Lines that are too long reduce system efficiency. We optimized the routing to maintain maximum performance.
Lack of Line Protection
The installed pipe cover protects components and ensures a clean, durable finish.
AirGreen Expertise in HVAC Installation on the North Shore
We regularly carry out similar installations in Lorraine, Blainville, Boisbriand, Laval, and throughout the North Shore. Each project is unique, but our methodology remains constant:
- Precise thermal evaluation
- Optimal sizing
- Installation compliant with RBQ standards
- Prompt after-sales service
Our technicians have perfect mastery of FUJITSU multi-zone systems, which guarantees reliable and durable installation.
Client Testimonial
The owner of this residence in Lorraine was looking for a quiet, high-performance, and visually discreet solution. After the installation:
- He noted an immediate improvement in thermal comfort
- The sound level remained very low, even in heating mode
- The exterior aesthetics were preserved thanks to the pipe cover
Recommended Maintenance to Maximize Lifespan
To ensure the longevity of this FUJITSU Aquila XLTH heat pump, we recommend:
- Filter cleaning every 3 months
- Annual professional maintenance
- Checking lines and connections
Regular HVAC maintenance helps maintain performance and prevent costly breakdowns.
Conclusion: An Installation Perfectly Adapted to Lorraine's Realities
This FUJITSU dual-zone heat pump installation project in Lorraine demonstrates the importance of a rigorous technical approach adapted to the building. Every detail—from the positioning of the outdoor unit to the finish of the lines—contributes to the overall performance of the system.
At AirGreen, we continue to support homeowners in Montreal, Laval, Longueuil, the North Shore, and the South Shore in their HVAC projects with durable, efficient, and perfectly executed solutions.
The job tools
Two quick checks with real numbers: what heat costs, and what your current heaters add up to in BTU/h.
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.
How the job unfolds
The main steps of this kind of job at AirGreen. Every house has its quirks: the estimate brings them out.
We look at the room, the outside wall, the line route and where the outdoor unit will go. That is where the capacity gets chosen.

What we check on a job like this one
Each number is a point we check on site. Switch between summer and winter to watch air and heat move.
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.

The right pages, at the right time
Four statements: true or false?
It all comes down to details you have just seen.
1. In heating mode, the outdoor unit can produce water.
During defrost cycles. That water must drain away without forming ice.
2. You pick the capacity with a simple square-footage rule.
Windows, insulation, orientation and how the room is used all count. Capacity is chosen on site.
3. A multi-zone connects several indoor heads to a single condenser.
One head per room, all on the same condenser. Each room keeps its own temperature.
4. The disconnect can sit behind the patio furniture.
It must stay accessible: it is what shuts the unit off for service.
