Strategic HVAC Installation to Maximize Comfort in a LaSalle Home
At AirGreen, we recently completed a high-performance, dual-zone HVAC installation in LaSalle, on Montreal's South Shore, in a residential property that required a solution that was discreet, powerful, and perfectly suited to Quebec winters. The client chose a FUJITSU Aquila XLTH R32 36,000 BTU heat pump, a system renowned for its ability to maintain exceptional performance even in extreme temperatures.
This project presented several interesting technical challenges, particularly related to the exterior brick configuration of the building, the installation height, and the optimization of refrigerant line routing.
Why choose a Dual-Zone Heat Pump in LaSalle?
An ideal solution for multi-space homes
The dual-zone configuration allows for independent control of two distinct spaces. In this specific case, the client wanted to efficiently air condition:
- The main living room (open living area)
- An upstairs bedroom
This approach offers several concrete advantages:
- Personalized comfort in each room
- Reduced energy consumption
- Less outdoor clutter compared to two separate systems
- Flexibility for future expansion to a multi-zone system
Adapted to Montreal's harsh climate
The FUJITSU Aquila XLTH model is specifically designed for the Quebec climate. Thanks to its advanced technology:
- Efficient heating down to -26°C
- Power maintenance even in extreme conditions
- Stable and quiet operation
In a region like LaSalle, where temperature fluctuations are significant, this type of system represents a strategic long-term investment.

Indoor Unit Configuration
For this installation in LaSalle, we chose an optimized combination:
- 1 wall-mounted unit for the living room (higher capacity)
- 1 wall-mounted unit for the bedroom (adapted capacity)
This distribution allows for uniform heat and air conditioning distribution, while avoiding unnecessary overloads.
Technical Challenges Encountered During Installation
1. High Installation on Brick Wall
As seen in the project, the outdoor unit was installed high up on a brick wall. This configuration presents several constraints:
- Need for a robust and perfectly anchored wall mount
- Vibration management to prevent resonance
- Clearance requirements to ensure optimal ventilation
At AirGreen, we used reinforced brackets with shock absorbers, guaranteeing stability and durability.
2. Refrigerant Line Routing
The routing of refrigerant lines was a major challenge:
- Discreet routing along the wall
- Protection against the elements
- Minimizing visual impact
We installed a clean and aligned protective conduit, ensuring both aesthetics and protection.
3. Drainage and Electrical Management
Another crucial element:
- Installation of an efficient drainage system to prevent freezing
- Secure electrical connection compliant with standards
Every detail was handled with precision to ensure a reliable and durable installation.
Common Mistakes to Avoid in This Type of Installation
Thanks to our experience in Greater Montreal, we often observe errors during similar HVAC installations:
Incorrect Outdoor Unit Positioning
- Too close to the wall → poor air circulation
- Too low → snow and ice accumulation
System Undersizing
Choosing insufficient capacity leads to:
- Poor performance
- Excessive consumption
- Premature wear
Non-compliant Bracket Installation
Inadequate brackets can cause:
- Excessive vibrations
- Long-term detachment risks
At AirGreen, we systematically avoid these errors through a rigorous technical analysis before each installation.
