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.

Conclusion: An Exemplary HVAC Installation in Outremont
This FUJITSU Aquila R32 36,000 BTU dual-zone heat pump installation in Outremont once again demonstrates the importance of a job well done.

At AirGreen, we don't just install a heat pump. We deliver a complete, durable solution perfectly adapted to the realities of Quebec's climate.
The job tools
Two quick checks with real numbers: what heat costs, and what your current heaters add up to in BTU/h.
Conversion: 1 W = 3.412 BTU/h. An indication, not a load calculation: baseboards and furnaces are often stronger than the real need, and they can stay as backup. AirGreen confirms the capacity on site.
How the job unfolds
The main steps of this kind of job at AirGreen. Every house has its quirks: the estimate brings them out.
We look at the room, the outside wall, the line route and where the outdoor unit will go. That is where the capacity gets chosen.
Model, capacity and price, in writing. We also check whether the model qualifies for assistance programs.
Floors and furniture protected, wall plate position marked level, wall opening located.
A single opening, with the slope the drain needs to flow outside.
Set on a stand raised above the snow, with the clearances the manufacturer requires.
Connected, insulated and protected. The opening is then sealed against water, cold air and insects.
A dedicated circuit and an accessible disconnect near the outdoor unit.
Leak test, vacuum, then start-up and a check of heating and cooling.
Remote, modes, filters: we show you the essentials before we leave.

What we check on a job like this one
Each number is a point we check on site. Switch between summer and winter to watch air and heat move.
In summer, the outdoor unit rejects the house's heat outside.
Generic illustration of this type of installation, not a survey of this job site. Tap a number.
Mounted level on a wall plate, high enough for the air to reach the whole room, with enough space around it to slide the filters out easily.
The refrigerant lines, the communication cable and the drain go through the wall in a single opening, sealed against water, cold air and insects.
Two insulated copper pipes connect the two units. Outside, a line cover can protect them from sun, knocks and weather.
A shut-off switch near the outdoor unit isolates it safely for service. It must stay accessible at all times.
The compressor and the fan. In heating mode it captures heat from the outdoor air, even in winter, and moves it inside.
On the ground or on the wall, it keeps the unit above accumulated snow. The unit stays clear and defrost water can drain away.
The fan needs to blow freely. Storage, a fence or a wall too close, and efficiency drops while noise goes up.
Is your home ready?
Check what applies at your place. A "no" is not a refusal: it is what we sort out during the estimate.
Good habits, once the unit is in place
Six simple habits that keep the unit going. Your list stays on this device.
What to do, season by season
Three habits per season for this unit. They take a few minutes and prevent many calls.
- Clean the indoor unit's filters.
- Clear leaves and debris left on the outdoor unit by winter.
- Test cooling before the first hot days.
- Clean the filters more often when the unit runs a lot.
- Keep plants away from the outdoor unit.
- Check that no water drips from the indoor unit.
- Rake the leaves around the outdoor unit.
- Test heating before the first cold days.
- Book periodic maintenance before winter.
- Keep snow away from the stand and the front of the unit.
- Let the unit defrost: it is normal.
- Never hit the ice on the fins; call us if the unit stays iced up.
The right pages, at the right time
Four statements: true or false?
It all comes down to details you have just seen.
1. In heating mode, the outdoor unit can produce water.
During defrost cycles. That water must drain away without forming ice.
2. You pick the capacity with a simple square-footage rule.
Windows, insulation, orientation and how the room is used all count. Capacity is chosen on site.
3. A multi-zone connects several indoor heads to a single condenser.
One head per room, all on the same condenser. Each room keeps its own temperature.
4. The disconnect can sit behind the patio furniture.
It must stay accessible: it is what shuts the unit off for service.
