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

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.

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.
