Strategic HVAC Installation to Maximize Comfort in a Sainte-Catherine Residence
At AirGreen, we recently completed a full HVAC installation in a home located in Sainte-Catherine, on the South Shore of Montreal, showcasing our expertise in high-performance multi-zone systems. The project involved installing a 24,000 BTU FUJITSU Aquila XLTH R32 dual-zone heat pump, a solution perfectly suited for Quebec's harsh winters and increasingly hot summers.
From the first visit, our objective was clear: to provide optimal thermal comfort in two distinct zones of the house, while respecting the architectural constraints of the building and the client's expectations regarding aesthetics and energy performance.
A Dual-Zone Solution Perfectly Adapted to the Client's Needs
Needs Analysis and System Configuration
The residence had two main zones requiring independent temperature control: the living room on the ground floor and the master bedroom upstairs. After a precise thermal assessment, we recommended a 9,000 + 12,000 BTU configuration, ensuring an optimal balance between power and efficiency.
The FUJITSU Aquila XLTH R32 heat pump emerged as the ideal choice due to:
- Its efficient heating capacity down to -26°C
- Its exceptional energy efficiency (SEER2 23.5 | HSPF2 11.5)
- Its ENERGY STAR® Cold Climate certification
- Its quiet operation (indoor unit up to 19 dB)
Why This Model is a Strategic Choice in Quebec
In the climatic context of Montreal, Laval, Longueuil, North Shore, and South Shore, it is essential to choose a heat pump capable of maintaining its performance even in extreme conditions. The Aquila XLTH model is specifically designed for this, featuring:
- A high-efficiency INVERTER compressor
- A more ecological R-32 refrigerant
- An advanced defrost system with an integrated pan heater
Technical Details of the Outdoor Installation
Positioning and Wall Mount
Observing the project photo, it's clear that the outdoor unit was installed on a galvanized steel wall mount, securely fastened to the concrete foundation. This choice is never accidental.
We favor this type of installation for several reasons:
- To prevent snow and ice accumulation in winter
- To reduce vibrations transmitted to the ground
- To facilitate future HVAC maintenance
The unit is positioned at an optimal height, adhering to our standard recommendation of 10 to 12 inches minimum above ground level, which significantly extends the system's lifespan.
Conduit Management and Aesthetic Finish
A white pipe cover was installed horizontally along the wall to protect the refrigerant lines and ensure a clean finish. This detail is essential for:
- Protecting the lines from the elements
- Maintaining a uniform aesthetic with the facade
- Facilitating access for maintenance
We also took care to avoid any interference with existing elements, such as the adjacent fence and shrubs, by precisely adjusting the unit's location.
Challenges Encountered on This Project in Sainte-Catherine
Space Constraints and Limited Access
The back wall of the house offered restricted space between the foundation, the fence, and existing vegetation. This necessitated:
- Precise positioning planning
- The use of a compact yet robust wall mount
- Rapid installation to minimize impact on the site
Vibration and Noise Management
Even though the FUJITSU model is known for its quiet operation (52 dB outdoors), we added anti-vibration supports to eliminate any sound transmission to the building's structure.
Adaptation to Electrical Standards
The unit operates on a 220V circuit with an MCA of 24A and an MOP of 25A. We upgraded the electrical panel to ensure power supply compliance with RBQ standards.
Final Result: Performance, Discretion, and Efficiency
Once the installation was complete, the system was commissioned with a full test:
- Verification of refrigerant pressures
- Calibration of indoor units
- Heating test under simulated conditions
The result is a perfectly balanced system offering:
- Uniform comfort in both zones
- Significant reduction in energy costs
- Intuitive use thanks to independent remote controls
LogisVert Subsidy: A Major Financial Advantage
