An optimized HVAC installation to face the Quebec winter in Blainville
In Blainville, on the North Shore, we recently carried out an installation of a FUJITSU ORION XLTH+ 15,000 BTU wall-mounted heat pump in a single-family home exposed to winter winds and frequent snow accumulation. This project perfectly illustrates the rigorous approach we adopt at AirGreen to ensure optimal performance, even in the most demanding conditions of the Quebec climate.
From the first technical visit, several elements caught our attention: a north-facing brick facade, limited outdoor space, and critical snow management around the planned location for the outdoor unit. The client was looking for a reliable solution to replace their electric baseboard heaters while improving their overall comfort, summer and winter.
A tailored solution: FUJITSU ORION XLTH+ 15,000 BTU
Why this model was chosen
The choice of the FUJITSU ORION XLTH+ 15,000 BTU quickly became evident for several technical and practical reasons:
- Effective heating down to -30°C, essential for Blainville winters
- Excellent energy performance (SEER2 28.7 / HSPF2 13.0)
- Eligibility for the LogisVert subsidy ($1,296)
- R-32 refrigerant, more ecological and efficient
- Silent operation, ideal for a quiet residential area
- Integrated Wi-Fi, for smart remote control
Key technical data of the installed system
- Capacity: 15,000 BTU
- Gas: R-32
- Voltage: 220V
- Outdoor sound level: 51 dB(A)
- Piping: 1/4 – 3/8
- Heating performance down to -30°C
- AHRI: 216018257
- ENERGY STAR® Cold Climate certification
These features make this heat pump a perfectly adapted solution to the realities of the North Shore, particularly in cities like Blainville, Laval, or Terrebonne.
Technical challenges encountered during installation
Snow management and elevation of the outdoor unit
One of the most critical aspects of this project concerned the installation of the outdoor unit. As seen on the construction site, snow accumulation on the ground could pose several problems:
- Airflow blockage
- Ice accumulation under the unit
- Reduced performance in defrost mode
To counter this, we installed the unit on a raised aluminum support, solidly anchored, allowing for:
- Sufficient height to prevent snow burial
- Better drainage of defrost water
- Reduced vibrations thanks to anti-vibration pads
This type of support is highly recommended for any HVAC installation in the Montreal area, particularly on the North Shore.
Strategic positioning against the brick wall
The brick rear wall presented another challenge: ensuring solid anchoring while avoiding any vibration transmission to the building structure.
We have:
- Used specialized masonry anchors
- Adjusted attachment points to ensure perfect stability
- Respected minimum distances for optimal ventilation
Key steps of the HVAC installation
1. Thermal analysis and sizing
Before any installation, we performed a precise calculation based on:
- The surface area of the space
- Existing insulation
- The orientation of the house
- Heating and cooling needs
The 15,000 BTU proved to be perfectly sized for the main living area.
2. Indoor unit installation
The indoor unit was installed in a central location to maximize:
- Uniform air distribution
- Comfort in adjacent rooms
- Overall energy efficiency
We also optimized the orientation of the louvers for balanced airflow.
3. Piping routing and finishing
We carried out a discreet routing of the refrigerant lines with:
- Complete line protection
- Optimal sealing
- Professional aesthetic finish
4. Commissioning and testing
Once the installation was complete:
- Complete vacuum draw
- Pressure checks
- Heating and cooling mode tests
- Wi-Fi system calibration
Concrete results for the client
After the installation, the benefits were immediate:
Improved thermal comfort
- Stable temperature throughout the house
- Elimination of cold spots
- Uniform heating even in severe cold
Reduced energy costs
By replacing electric baseboard heaters:
- Significant decrease in Hydro-Québec bill
- Improved overall energy efficiency
Silence and discretion
The client particularly appreciated:
- The low noise of the outdoor unit, even in winter
- The almost inaudible indoor operation
Practical tips for a successful installation in Blainville
Avoid ground-level installation
Installing an outdoor unit directly on the ground is a common mistake. This can lead to:
- Ice accumulation
- Poor drainage
- Decreased performance
Adequate elevation is essential.
Choose a model adapted to extreme cold
Not all heat pumps are designed for Quebec. Choosing a model like the FUJITSU ORION XLTH+ ensures:
- Continuous heating
- Less reliance on auxiliary systems
Do not neglect installation
Even the best machine can underperform if poorly installed. A professional HVAC installation is essential to:
- Maximize lifespan
- Ensure safety
- Optimize performance
