An Optimized HVAC Installation for a Demanding Residential Triplex
At AirGreen, we recently completed a complete HVAC installation in Town of Mount Royal, an area known for its well-maintained properties and high thermal comfort requirements. The mandate was to replace an aging system with a modern, high-performance solution perfectly suited for a multi-zone dwelling.
The choice fell on a FUJITSU Aquila XLTH R32 TripleZone 36,000 BTU heat pump, a system renowned for its ability to provide precise comfort in multiple zones while maintaining exceptional efficiency, even during Montreal's harsh winters.
Why This FUJITSU System Was the Ideal Choice for Town of Mount Royal
A Perfectly Suited Multi-Zone Configuration
In this property, three distinct zones needed to be air-conditioned and heated independently:
- A main open-concept ground floor
- An upper floor with closed bedrooms
- A partially finished basement
Thanks to its TripleZone design, the FUJITSU Aquila XLTH can power three indoor units simultaneously, each adjusted to the specific needs of the occupants. This flexibility is essential in residences where living habits vary from one floor to another.
Exceptional Performance in Quebec's Climate
The installed model (AOUH36KWAH4) is designed to operate efficiently down to -26°C, which is essential in the climatic context of Town of Mount Royal and Greater Montreal.
Key features:
- Stable heating capacity in extreme cold
- Inverter Technology for automatic power adjustment
- R-32 refrigerant, more ecological and efficient
- ENERGY STAR® (cold climate) certification
Technical Challenges Encountered on Site
Outdoor Installation in Winter: Managing Snow and Frost
One of the striking elements of this installation, visible in the photo, is the presence of snow and ice around the outdoor installation area. This imposes significant technical constraints.
To ensure optimal performance and avoid long-term problems, we:
- Installed the outdoor unit on a robust raised aluminum support
- Ensured sufficient height to prevent snow accumulation
- Stabilized the base with a solid slab to prevent vibrations
This type of mounting is essential to ensure the system's durability in Quebec's winter conditions.
Aesthetic Integration on a Brick Facade
The building features a red brick facade with distinctive architectural accents. The system's integration therefore had to be discreet and neat.
Our solutions:
- Compact and clean routing of refrigerant lines
- Strategic positioning to minimize visual impact
- Orderly management of cables and piping (visible to the right of the unit)
The result is an installation that is both functional and visually harmonious.
Technical Details of the Installed Heat Pump
Outdoor Unit
- Model: FUJITSU AOUH36KWAH4
- Capacity: 36,000 BTU

Interior Configuration
In this project, we recommended a balanced combination of wall-mounted units to optimize air distribution:
- A main unit for the living area
- Two secondary units for the bedrooms and basement
Each unit offers quiet operation (down to 19 dB(A)), ideal for daily comfort.
Key Stages of the HVAC Installation
1. Complete Thermal Analysis
Before any installation, we conducted a detailed assessment:
- Area of the zones
- Building insulation
- Solar orientation
- Specific occupant needs
2. Selection of the Optimal Configuration
The flexibility of the FUJITSU system allowed us to precisely adapt the power of the indoor units to each zone.
3. Installation of Ducts and Connections
- Routing of refrigerant lines through existing walls
- Perfect sealing to prevent any energy loss
- Electrical installation compliant with RBQ standards
4. Commissioning and Calibration
- Pressure and vacuum test
- Performance verification
- Calibration of units for optimal operation
Subsidy and Savings for the Client
This system is eligible for Hydro-Québec's LogisVert grant, allowing the client to benefit from a refund of up to $2,928.
Expected results:
- Significant reduction in heating costs
- Improved thermal comfort
- Accelerated return on investment
Practical Advice for a Similar Installation
Avoiding Common Mistakes
- Installing the outdoor unit too close to the ground (risk of freezing)
- Neglecting zone balance
- Choosing inadequate power
Recommended Best Practices
- Always elevate the outdoor unit in snowy climates
- Plan for annual maintenance
- Optimize the placement of indoor units
