A Custom HVAC Installation in a Residential Space with Real Constraints
In Pointe-Claire, in a quiet residential area of Montreal's West Island, we recently completed a full HVAC installation of a FUJITSU Aquila R32 36,000 BTU dual-zone wall-mounted heat pump (model AOUH36KWAS4). This project perfectly illustrates our approach: analyzing the actual building constraints, optimizing the configuration of the indoor units, and ensuring stable performance for both air conditioning and heating.
The client wanted an efficient solution for two distinct zones: a main living area and a secondary bedroom. The objective was clear: improve thermal comfort year-round, reduce energy consumption, and avoid common installation errors observed in other projects in the Montreal, Laval, Longueuil, North Shore, and South Shore regions.
Technical Analysis and Choice of the FUJITSU Aquila Heat Pump
Why this specific model?
We recommended the FUJITSU Aquila R32 Dual-Zone 36,000 BTU heat pump for several concrete reasons:
- Adapted capacity: 36,000 BTU allowing two zones to be powered without performance loss
- Configuration flexibility: possibility to combine different indoor units (e.g., 12,000 + 24,000 BTU)
- R-32 refrigerant: more eco-friendly and efficient
- Operation down to -15°C: ideal for Quebec winters
- High energy efficiency: SEER2 ~22.0, HSPF2 ~10.0
- Low noise level: approximately 56 dB(A) outdoors
This type of system is particularly relevant for multi-story residences or houses with separate zones, as was the case here in Pointe-Claire.
Challenges Encountered During Installation
Strategic Positioning of the Indoor Unit
As seen in the project, the main indoor unit was installed above a door, a common situation in homes where wall space is limited. This type of configuration requires absolute precision:
- Respect for minimum clearances
- Optimal airflow management
- Future access for HVAC maintenance
We adjusted the airflow angle and checked air circulation to avoid cold or hot spots.
Conduit Passage and Aesthetic Finish
Another major challenge concerned the routing of refrigerant pipes and electrical cables. In this project:
- Conduits were neatly concealed to preserve interior aesthetics
- Wall outlets were sealed to prevent air or moisture infiltration
- Particular attention was paid to visual integration with the existing decor
This type of finish distinguishes a professional installation from a standard one.
AirGreen Installation Process: Rigor and Precision
Key Steps Performed
Our team followed a strict process to ensure a lasting installation:
- Initial on-site inspection
- Thermal load calculation
- Selection of suitable indoor units
- Installation of reinforced wall brackets
- Routing of refrigerant lines (with mechanical protection)
- Complete vacuum pull (stable micron test)
- Leakage verification
- System commissioning and calibration
The micron test is a critical step that we apply systematically. It helps detect any micro-leaks and guarantees the longevity of the system.
Final Result: Comfort, Silence, and Efficiency
Once the installation is complete, the system offers:
- Homogeneous temperature distribution
- Silent operation, ideal for living spaces
- Significant reduction in energy costs
- Independent management of the two zones
The client now benefits from constant comfort, summer and winter, without relying on an energy-intensive central system.
Grant and Profitability
This installation is eligible for Hydro-Québec's LogisVert grant, with an amount of approximately $1,180 (according to current criteria).
This significantly reduces the initial cost while investing in a sustainable solution.
Common Errors to Avoid in this Type of Installation
In Pointe-Claire, as elsewhere on the South Shore, North Shore, Laval, and Montreal, we often observe the same errors:
- Incorrect sizing (insufficient or excessive BTUs)
- Installation too close to the ceiling or an obstruction
- Absence of micron test
- Poor drainage management
- Neglected aesthetics
At AirGreen, every project is designed to avoid these issues from the outset.
Field Experience Feedback: A Typical Optimized Case
This project reflects a common situation in West Island homes:
- Limited space for wall units
- Need to control two independent zones
- Importance of interior aesthetics
- Search for a reliable and silent solution
Thanks to our expertise in HVAC installation in Montreal and its surroundings, we were able to turn these constraints into advantages.
