A Strategic HVAC Installation in the Heart of Verdun for Optimal Year-Round Comfort
In a typical residential building in Verdun, our AirGreen team recently completed a full HVAC installation of a FUJITSU Aquila XLTH R32 36,000 BTU dual-zone heat pump. This project perfectly illustrates the technical challenges often encountered in dense urban environments in Montreal, while demonstrating our ability to offer sustainable, efficient, and perfectly adapted solutions to local realities.
The client wanted to replace an old, inefficient system while improving thermal comfort in two distinct areas of their home. The objective was clear: achieve reliable performance even in harsh winters, while optimizing energy consumption and maximizing available subsidies.
Why the FUJITSU Aquila XLTH Heat Pump Was the Ideal Choice
Performance Adapted to Montreal's Climate
The FUJITSU Aquila XLTH R32 36,000 BTU stands out for its ability to maintain high efficiency down to -26°C, making it a particularly relevant choice for residences located in Montreal, Laval, Longueuil, North Shore, and South Shore. In this project in Verdun, this feature was essential, as the wind-exposed building required a solution capable of providing constant heat without energy overload.
Key Technical Features
- Total Capacity: 36,000 BTU
- Configuration: DualZone (2 independent zones)
- Outdoor Model: AOUH36KWAH4
- Refrigerant: R-32 (more ecological and efficient)
- Certification: ENERGY STAR® (cold climate included)
- SEER2: 22.0
- HSPF2: 10.0
- Outdoor Sound Level: 56 dB(A)
- LogisVert Grant: up to $2,928
This system allows for independent management of two spaces, which significantly improves comfort and reduces energy loss.
Challenges Encountered During Installation in Verdun
Rooftop Installation: Constraints and Solutions
The image associated with this project clearly shows that the outdoor unit was installed on the building's roof, a common configuration in Verdun. This approach offers several advantages, but also significant technical challenges:
- Limited access: transport of the unit to the roof with specialized equipment
- Stability and vibration: installation on elevated support with dampers
- Drainage management: prevention of ice accumulation
- Wind exposure: need for solid anchoring
At AirGreen, we installed the outdoor unit on an elevated aluminum structure, fixed on a reinforced base with anti-vibration supports. This method guarantees:
- Better system durability
- Reduced noise transmitted to the structure
- Protection against snow and water accumulation
Proximity to Ventilation Outlets
Another critical element visible in the installation was the proximity of a ventilation outlet (black chimney). It was essential to respect minimum distances to avoid:
- Recycling of hot/cold air
- Loss of efficiency
- Risks of condensation or freezing
We precisely adjusted the unit's positioning to ensure optimal airflow while respecting safety standards.
DualZone Configuration: A Smart Choice
Distribution of Indoor Units
In this project, the client needed to cool and heat:
- A main living room (zone 1)
- A bedroom (zone 2)
We installed:
- A 12,000 BTU indoor unit in the living room
- An 18,000 BTU indoor unit to cover the bedroom and adjacent areas
This configuration ensures:
- Uniform air distribution
- Independent control of each room
- Significant reduction in energy consumption
Advantages of a Dual-Zone Heat Pump
- Fewer outdoor units = cleaner installation
- Flexibility of use
- Better thermal comfort
- Long-term installation cost savings
Detailed Steps of the HVAC Installation
1. Initial Analysis and Sizing
We began with a comprehensive assessment of the dwelling:
- Total area
- Insulation
- Building orientation
- Client's specific needs
This allowed us to confirm that the 36,000 BTU model was perfectly suited.
2. Outdoor Unit Installation
- Installation of the elevated base
- Fixing with anti-vibration supports
- Checking level and stability
- Electrical connection (220V)
3. Routing of Refrigerant Lines
- Use of high-quality insulated lines
- Minimization of thermal losses
- Protection against weather
4. Installation of Indoor Units
- Strategic positioning for optimal diffusion
- Solid wall mounting
- Airflow tests
5. Commissioning and Testing
- Pressure test
- Inverter system verification
- Zone calibration
- Performance validation
Real Subsidies and Savings
Thanks to this model's eligibility for the LogisVert program, the client was able to benefit from a subsidy of $2,928.
Financial Impact:
- Immediate reduction in purchase cost
- Accelerated return on investment
- Reduced electricity bills
We assisted the client with all administrative procedures to ensure a quick receipt of the subsidy.
Common Mistakes to Avoid in a Similar Installation
Improper Positioning of the Outdoor Unit
A common mistake is installing the unit too close to obstacles or without considering the wind. This can reduce efficiency by up to 20%.
Undersizing the System
Choosing insufficient capacity leads to:
- Overconsumption
- Premature wear
- Constant discomfort
Neglecting Installation Quality
Even the best heat pump will not perform correctly if:
- Lines are poorly insulated
- Supports are unstable
- The system is not properly calibrated
At AirGreen, we focus on every detail to ensure a lasting result.
