A Rooftop HVAC Installation Perfectly Suited to Anjou's Urban Realities
In Anjou, in the east of Montreal, we recently completed a strategic and highly technical HVAC installation: a 36,000 BTU FUJITSU Aquila XLTH R32 TripleZone heat pump on the flat roof of a residential building. This type of installation requires absolute precision, both in terms of the outdoor unit's positioning and the management of refrigerant lines, especially in a dense urban environment.
The client wanted a solution capable of heating effectively in harsh winters while offering stable and quiet air conditioning in summer for three distinct zones of their home. After analyzing their needs, we recommended this specific Fujitsu model, known for its performance in cold climates and multi-zone flexibility.
Technical Challenges and Custom Solutions for this Anjou Project
Rooftop Installation: Stability, Vibration, and Durability
The outdoor unit was installed on a raised structure specially designed to:
- Ensure perfect stability on a roofing membrane
- Prevent vibrations transmitted to the building structure
- Maintain the unit at an optimal height to avoid snow accumulation in winter
The photo clearly shows our approach: a solid base combining metal support and treated wood blocks, allowing for uniform weight distribution and effective vibration absorption. This type of mounting is essential in Montreal, Laval, and on the South Shore, where winter conditions can compromise a poorly executed installation.
Management of Refrigerant and Electrical Lines
In this project, one of the main challenges was the discrete and efficient management of the refrigerant lines connecting the three indoor units to the outdoor unit. We have:
- Optimized routes to reduce performance losses
- Ensured complete insulation of the conduits to prevent thermal losses
- Integrated electrical wiring securely and in compliance with RBQ standards
Every detail has been considered to guarantee maximum performance and extended system longevity.
Why Choose the FUJITSU Aquila XLTH TripleZone Heat Pump?
Exceptional Performance in Quebec's Climate
The AOUH36KWAH4 model stands out for its ability to maintain heating performance down to -26°C, making it an ideal choice for winters in Montreal, Longueuil, or the North Shore.
Key features:
- Cooling Capacity: 36,000 BTU
- Heating Capacity at -15°C: 36,400 BTU
- Inverter Technology for precise power modulation
- R-32 Refrigerant: more ecological and efficient
- ENERGY STAR® (cold climate) Certification
This combination allows for significant savings on energy costs while maintaining constant comfort in each zone.
TripleZone Flexibility for Personalized Comfort
In this Anjou project, the chosen configuration allows for servicing three distinct zones, with indoor units adapted to the specific needs of each space. This offers:
- Independent temperature control
- Reduced energy losses
- Perfect adaptation to occupants' living habits
We have often installed this type of system in duplexes in Laval, triplexes in Montreal, or houses on the South Shore, with consistent results in terms of customer satisfaction.

LogisVert Subsidy: A Significant Financial Advantage
This installation is eligible for the Hydro-Québec LogisVert subsidy, which can be up to $2928. At AirGreen, we support our clients every step of the way to maximize this financial assistance.
This significantly reduces the initial cost while investing in a sustainable and energy-efficient solution.
Common Mistakes to Avoid in Rooftop HVAC Installation
Based on our experience in Montreal and the surrounding areas, here are the most common mistakes:
- Installing the unit directly on the membrane without adequate support
- Neglecting the insulation of refrigerant lines
- Undersizing the heat pump's capacity
- Ignoring the impact of wind and solar exposure
At AirGreen, every installation is carried out according to rigorous standards to avoid these issues.
Client Feedback and Results Achieved
The Anjou client observed from the first few weeks:
- A notable reduction in energy consumption
- Consistent thermal comfort in all three zones
- Quiet operation, even at full load
This type of feedback is common in our installations in Longueuil, Laval, and on the North Shore, confirming the reliability of this technology.
