A Strategic Rooftop HVAC Installation in the Heart of Outremont
In a neighborhood as dense and architecturally distinct as Outremont, every HVAC installation must be designed with precision, discretion, and durability. At AirGreen, we recently completed the installation of a FUJITSU Aquila R32 36,000 BTU dual-zone heat pump (model AOUH36KWAS4) on the flat roof of a residential building, in a demanding urban environment.
This project perfectly illustrates our approach: combining energy performance, aesthetic integration, and impeccable technical installation, even in complex conditions.
Specific Technical Challenges for this Rooftop Installation
Limited Access and Controlled Logistics
The installation took place on a typical Outremont flat roof, with restricted access. Transporting the FUJITSU Aquila outdoor unit required precise coordination:
- Use of adapted equipment for safe lifting
- Protection of the roofing membrane
- Optimized positioning to limit vibrations and noise
Elevated Support and Enhanced Stability
As seen on site, we installed the unit on an elevated structure resting on treated wooden bases. This approach allows for:
- Avoiding any direct contact with the membrane
- Reducing risks related to snow accumulation
- Ensuring optimal mechanical stability
We then securely fastened the unit to a metal support, guaranteeing a durable installation against Quebec's climatic conditions.
Dual-Zone Configuration: A Smart Choice for this Project
Perfect Adaptation to Client Needs
The FUJITSU Aquila R32 36,000 BTU heat pump installed here supplies two distinct zones:
- A main living space (living room + kitchen)
- A more private area (bedroom or office)
This configuration allows for:
- Independent temperature control
- Improved energy efficiency
- Personalized comfort according to room usage
Possible Combinations
This model allows for several combinations of indoor units (7,000 to 24,000 BTU). In this Outremont project, we chose a balanced combination to maximize efficiency without oversizing.
Technical Details of the FUJITSU Aquila R32 36,000 BTU
Performance and Efficiency
- Cooling Capacity: 36,000 BTU
- Heating Capacity down to -15°C
- SEER2: 22.0
- HSPF2: 10.0
- EER2: 12.0
- COP at -8°C: 2.23 (field approximation)
These performances ensure excellent energy efficiency, significantly reducing electricity costs for the client.
Technology and Reliability
- INVERTER Compressor for intelligent modulation
- Eco-friendly R-32 refrigerant
- Blue Fin heat exchanger for anti-corrosion
- Outdoor sound level: 56 dB(A)
In a residential environment like Outremont, quiet operation is a key factor.
Refrigerant Line Management: A Critical Point Perfectly Executed
Clean and Secure Organization
For this installation, we grouped the refrigerant and electrical lines into a neat and well-secured bundle, visible in the photo:
- Complete insulation of ducts
- Protection against UV and weather
- Solid fastening to prevent any movement
Length and Optimization
As always at AirGreen:
- The first 15 feet are included
- Any additional length is precisely calculated
- No waste, no compromise on performance
Sealing and Professional Commissioning
Rigorous Micron Test
Before commissioning, we performed a micron test, an essential step that many installers neglect:
- Creation of a deep vacuum in the system
- Verification of micron stability
- Detection of potential micro-leaks
This process guarantees the system's longevity and prevents future problems.
Controlled Commissioning
Once the tests are validated:
- Opening of valves
- Pressure verification
- Calibration of indoor units
Subsidy and Profitability for the Client
This installation is eligible for the LogisVert subsidy:
- Amount: approximately $1,180 (recent update)
This significantly reduces the overall cost of the investment, while improving the thermal comfort of the home.
Common Errors Avoided in this Project
At AirGreen, we regularly correct poorly executed installations. Here's what we avoided here:
- Direct installation on the membrane (risk of damage)
- Poor management of refrigerant lines
- Absence of micron testing
- Incorrect sizing of zones
Every detail matters to guarantee a durable and high-performing installation.
