A perfectly suited dual-zone HVAC solution for a brick residence in Côte Saint-Luc
At AirGreen, we recently completed a dual-zone HVAC installation in a typical residential area of Côte Saint-Luc, characterized by brick buildings, restricted access, and very specific installation constraints. The client wanted a reliable solution to efficiently cool and heat two distinct areas of their home, while maximizing energy efficiency and minimizing outdoor noise.
We recommended and installed a FUJITSU Aquila XLTH R32 36,000 BTU Dual Zone heat pump, a system known for its exceptional performance in cold weather, perfectly suited to the realities of Montreal, Laval, Longueuil, North Shore, and South Shore.
Technical details of the installed system: performance and precision
A heat pump designed for Quebec winters
The installed model — FUJITSU Aquila XLTH (outdoor model AOUH36KWAH4) — offers remarkable performance:
- Cooling capacity: 36,000 BTU
- Efficient heating down to -26°C
- R-32 refrigerant gas (low environmental impact)
- ENERGY STAR® certified (cold climate included)
- SEER2: 22.0 | HSPF2: 10.0
- Outdoor sound level: 56 dB(A)
This system can power two independent zones, providing personalized comfort in each living space.
A technical installation in a challenging environment
Intelligent management of outdoor space
The image of this installation perfectly illustrates a common reality in Côte Saint-Luc: limited outdoor spaces, with proximity to windows, metallic structures, and existing ducts.
In this project, we had to:
- Install the outdoor unit on a stable concrete base, slightly elevated to prevent snow accumulation
- Work around an existing vertical duct without compromising access or ventilation
- Position the unit at a strategic distance from the window to limit vibrations and noise
Duct and wiring passage
One of the major challenges was to:
- Run refrigerant lines and wiring through a confined space
- Protect connections from the elements
- Ensure a clean and durable finish on a brick wall
We used precise fastening and sealing techniques to ensure a robust and aesthetic installation.
Interior configuration: tailor-made comfort for two zones
Choice of indoor units
For this residence, we selected a combination suited to the client's needs:
- A wall-mounted unit for the living room (main zone)
- A wall-mounted unit for an upstairs bedroom
Each unit was chosen based on:
- Area
- Insulation
- Sun exposure
- Client's usage habits
This approach allows for independent temperature management, improving comfort and reducing energy consumption.
Why this FUJITSU heat pump is ideal for Côte Saint-Luc
Consistent performance even in winter
Unlike many standard systems, XLTH (Extra Low Temperature Heating) technology allows for:
- Stable heat production even in very cold weather
- Reduced reliance on auxiliary heating systems
Quiet and discreet
In a dense residential area like Côte Saint-Luc, noise level is a critical factor. With only 56 dB(A) outdoors and indoor units that can go down to 19 dB(A), this system ensures optimal acoustic comfort.
Available subsidy: significant savings
This installation is eligible for the LogisVert d'Hydro-Québec subsidy, offering up to:
- $2,928 in reimbursement
