Strategic HVAC Installation for Optimal Comfort on the South Shore
In Saint-Lambert, on Montreal's South Shore, we recently completed the full installation of a FUJITSU Aquila XLTH R32 24,000 BTU dual-zone heat pump, a choice particularly well-suited to Quebec's climatic realities. This project perfectly illustrates AirGreen's approach: rigorous execution, adaptation to building constraints, and maximum optimization of energy efficiency.
The client wanted to improve the thermal comfort of two distinct zones in their residence, while reducing their energy consumption and benefiting from available subsidies. The objective was clear: to obtain a reliable, high-performance, and discreet solution, capable of operating efficiently even in extreme cold.
Project Analysis and Choice of FUJITSU Aquila XLTH Heat Pump
Why a Dual-Zone Heat Pump?
In this Saint-Lambert residence, the need was to serve two main areas: a living room on the ground floor and a bedroom upstairs. A dual-zone heat pump allows independent temperature control in each room, offering:
- Personalized comfort management
- Significant reduction in energy consumption
- Flexibility of use according to lifestyle habits
Key Technical Features of the Installed Model
The chosen model, FUJITSU Aquila XLTH R32 (AOUH24KWAH3), is renowned for its exceptional performance in cold climates:
- Cooling capacity: 24,000 BTU
- Effective heating capacity down to -26°C
- SEER2: 23.5 | HSPF2: 11.5 | EER2: 13.5
- R-32 refrigerant (more ecological and efficient)
- Outdoor sound level: 52 dB(A)
- ENERGY STAR® certified (cold climate included)
This system also allows for significant modularity with different combinations of indoor units, perfectly adapted to the building's configuration.
Challenges Encountered During Installation in Saint-Lambert
Outdoor Wall Installation on Brick Structure
As seen in the project, the outdoor unit was installed on a brick wall with a reinforced wall bracket. This configuration presents several technical challenges:
- Ensuring solid fixation without compromising wall integrity
- Minimizing vibrations to avoid noise pollution
- Ensuring sufficient clearance for airflow
We used robust brackets with integrated shock absorbers to stabilize the unit and extend its lifespan.
Management of Refrigerant and Electrical Conduits
The routing of refrigerant lines and wiring was optimized to:
- Reduce thermal losses
- Maintain a clean and discreet aesthetic
- Comply with RBQ standards for HVAC installation
Conduits were carefully insulated and precisely fixed to prevent sagging or premature wear.
Strategic Positioning of Indoor Units
Incorrect positioning of wall units can compromise the overall system performance. In this project:
- The living room unit was placed to maximize air distribution in an open space
- The bedroom unit was positioned to avoid direct drafts
This optimization work is essential to ensure constant and uniform comfort.
AirGreen Installation Process: Rigor and Precision
Key Steps Performed on This Project
- Complete thermal evaluation
- Selection of the appropriate system (precise sizing)
- Preparation of supports and conduit passages
- Installation of outdoor and indoor units
- Refrigerant and electrical connection
- Vacuum test and leak check
- System commissioning and calibration
Each step is performed by certified refrigeration technicians, ensuring a compliant and durable installation.
Real Performance in Quebec Conditions
One of the main advantages of the FUJITSU Aquila XLTH is its ability to maintain high performance even in harsh winters. Unlike many standard systems:
- It continues to heat efficiently down to -26°C
- It maintains significant heating power at -15°C (25,200 BTU)
- It includes a pan heater to prevent freezing
This makes it an ideal solution for residents of Montreal, Laval, Longueuil, the North Shore, and the South Shore.
LogisVert Subsidy: Significant Savings
This installation in Saint-Lambert is eligible for the LogisVert subsidy of $1,944, significantly reducing the initial cost.
At AirGreen, we support our clients through all steps:
- Eligibility verification
- Complete documentation
- Submission in compliance with requirements
Advantages of R-32 Refrigerant
The choice of R-32 gas in this installation brings several benefits:
- Better energy efficiency
- Reduced environmental impact
- Less refrigerant charge required
It is a more sustainable solution, in line with new HVAC industry standards.
Client Testimonial – Saint-Lambert
The client particularly appreciated:
- The speed of installation (completed in one day)
- The cleanliness of the site
- The very low noise level of the system
- The immediate comfort obtained
Since installation, both zones have enjoyed stable temperatures, summer and winter.
Common Mistakes to Avoid in This Type of Installation
Even for a high-performance heat pump, certain errors can compromise the result:
- Incorrect system sizing
- Inadequate positioning of indoor units
- Outdoor installation too low (risk of snow and ice)
- Poorly insulated conduits
At AirGreen, we eliminate these risks through detailed planning and rigorous execution.
