Installation of a FUJITSU Aquila R32 36,000 BTU dual-zone heat pump in Saint-Bruno
Real project in Saint-Bruno: installation of a FUJITSU Aquila 36,000 BTU dual-zone heat pump. Optimal comfort, expert HVAC installation on the South Shore, subsidies and energy performance delivered.
Take a tour of the installation
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.

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.
Precise and Durable HVAC Installation for Optimal Comfort on the South Shore
At AirGreen, we regularly perform HVAC installations on the South Shore, particularly in Saint-Bruno, where thermal comfort requirements are high due to significant climatic variations. This project highlights the installation of a FUJITSU Aquila R32 36,000 BTU dual-zone heat pump (outdoor model AOUH36KWAS4), a solution perfectly suited for a residence requiring independent management of two distinct areas.
A Dual-Zone Configuration Perfectly Adapted to the Client's Needs
On-site Needs Analysis
During our technical visit to Saint-Bruno, the client wanted to improve the thermal comfort of two main zones:
- An open living space (living room + kitchen)
- A more isolated zone upstairs (master bedroom)
The main constraint was to maintain a stable and independent temperature in these two zones, without resorting to an expensive and invasive central system.
Chosen Solution: FUJITSU Aquila DualZone
We recommended a FUJITSU Aquila R32 36,000 BTU heat pump, configured in dual-zone with:
- A 24,000 BTU indoor unit for the main area
- A 12,000 BTU indoor unit for the upstairs
This combination provides a perfect balance of power, efficiency, and comfort.
Technical Details of the Installed Heat Pump
Performance and Energy Efficiency
The FUJITSU Aquila R32 heat pump stands out for its reliable performance in Quebec conditions:
- Cooling capacity: 36,000 BTU
- Heating capacity down to -15°C
- SEER2: 22.0
- HSPF2: 10.0
- EER2: 12.0
- R-32 refrigerant: more ecological and efficient
Although this model is not Cold Climate ENERGY STAR certified, it offers excellent performance for much of the year, particularly for air conditioning and moderate heating.
Design and Durability
- INVERTER compressor for intelligent modulation
- Blue Fin exchanger against corrosion
- Outdoor sound level: 56 dB(A) (ideal for a residential neighborhood like Saint-Bruno)
- Voltage: 220V
Installation Review: AirGreen's Precision and Rigor
Outdoor Unit Installation
As visible on site, we installed the outdoor unit on elevated wall mounts with anti-vibration dampers. This choice offers several advantages:
- Protection against snow accumulation in winter
- Reduction of vibrations transmitted to the structure
- Better air circulation under the unit
We also ensured:
- Compliance with recommended minimum distances
- Perfect alignment with the facade
- Efficient drainage installation
Refrigerant Line Management
A crucial point in any heat pump installation is the quality of the piping:
- Use of high-performance insulated conduits
- Discrete routing along the exterior wall
- Protection against UV and bad weather
We performed a complete vacuum (micron test) to guarantee the absence of humidity and micro-leaks, thus ensuring the longevity of the system.
Indoor Unit Installation
Each indoor unit was strategically positioned to:
- Maximize air diffusion
- Avoid dead zones
- Minimize perceived noise
The wall brackets were reinforced to ensure perfect stability.
Challenges Encountered and Solutions Provided
Restricted Outdoor Space
The backyard had limited space, with restricted access. We opted for:
- A compact installation against the wall
- Precise positioning planning to facilitate future maintenance
Aesthetic Integration
The client wanted a discreet installation. Therefore, we:
- Aligned the conduits with the architectural lines of the house
- Used pipe covers matching the facade
Subsidies and Profitability
This installation is eligible for the LogisVert subsidy, with an amount of approximately $1,180 (according to the latest updates).
Financial Impact
- Reduction of initial cost
- Significant long-term energy savings
- Accelerated return on investment

The big day, step by step
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 would it look like at your place?
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.

Your own project, step by step
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.
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.
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.
