An HVAC Installation Designed to Withstand Laval's Harsh Winters
At AirGreen, every HVAC installation is designed based on the climatic realities of Greater Montreal, and particularly Laval, where winters impose high technical demands. In this specific project, our team installed a FUJITSU ORION XLTH 12,000 BTU wall-mounted heat pump (model AOUH12KZAH1 / ASUH12KZAS) in a residential environment where heating performance was the absolute priority.
The project image clearly shows a carefully executed outdoor installation, mounted on a raised aluminum support, positioned against a brick wall, with optimal clearance from snow and surrounding elements. This type of configuration is never left to chance.
Why This FUJITSU ORION XLTH Model Was the Ideal Choice
Exceptional Performance Down to -26 °C
In a context like Laval, where temperatures regularly drop below -20 °C, a standard heat pump would have been insufficient. The FUJITSU ORION XLTH KZAH model stands out for:
- An effective heating capacity down to -26 °C
- A power output of up to 16,600 BTU at -15 °C
- Advanced Inverter technology, ensuring constant modulation
This means remarkable thermal stability, without unpleasant variations.
Superior Energy Efficiency
This system boasts impressive performance:
- SEER2: 30.5
- HSPF2: 12.7
- ENERGY STAR® Cold Climate certification
For the client, this translates into a significant reduction in energy costs, especially compared to traditional electric baseboards.
Technical Details of the Installation in Laval
Strategic Positioning of the Outdoor Unit
The outdoor installation visible in the image reveals several important technical decisions:
- Raised support: essential to prevent snow accumulation and ensure effective drainage
- Optimized distance from the wall for air circulation
- Installation on a stable metal base, reducing vibrations
- Orientation considering prevailing winds
We also took care to maintain easy access for future maintenance, an aspect often overlooked by less experienced installers.
Drainage and Freeze Management
In winter, water generated by defrost cycles can become problematic. In this project:
- The base is designed to effectively drain water
- Positioning prevents any accumulation under the unit
- The system includes intelligent defrost management
Result: no excessive ice formation, even during frequent freeze/thaw cycles.
Challenges Encountered and Solutions Provided
Restricted Space and Proximity to Structures
The client had limited outdoor space, with:
- A brick wall
- An adjacent structural drop
- Vegetation nearby
Our team had to:
- Precisely adjust the location to maintain regulatory clearances
- Avoid any obstruction of airflow
- Ensure a clean and discreet aesthetic
Stabilization on Winter Ground
The partially snowy ground presented an additional challenge. We used:
- A perfectly leveled base
- Anti-vibration mounts
- Solid fastening ensuring durability
The Crucial Role of R-32 Refrigerant
This heat pump uses R-32, a strategic choice for several reasons:
- Reduced environmental impact
- Improved thermal efficiency
- Compatibility with future standards
For homeowners in Laval and Greater Montreal, this is a sustainable investment.
Acoustic Comfort: An Often Underestimated Advantage
In this installation:
- Outdoor sound level: 47 dB(A)
- Indoor operation: as low as 23 dB(A)
Even in a dense residential environment, this heat pump remains discreet. The client benefits from thermal comfort without noise pollution.
LogisVert Subsidy: A Tangible Financial Benefit
This model is eligible for a $1,200 subsidy through the LogisVert program.
We assisted the client with:
- Eligibility validation
- Necessary documentation
- The claim process
This significantly reduces the initial cost of the installation.
Best Practices Applied During This Installation
At AirGreen, we consistently adhere to high standards:
Technical steps performed:
- Complete thermal analysis of the space
- Selection of appropriate tonnage (12,000 BTU)
- Installation of supports and anchoring
- Routing of refrigerant lines (1/4 – 3/8)
- Complete vacuum pull
- Pressure verification
- Commissioning and calibration
What we absolutely avoid:
- Ground installation without elevation
- Poor drainage
- Poorly insulated piping
- Inadequate orientation
Tangible Results for the Client
After installation:
- Stable temperature even in very cold weather
- Reduced energy consumption
- No annoying noise
- Constant comfort throughout the serviced area
Maintenance Tips to Maximize Performance
To ensure the longevity of the FUJITSU ORION XLTH wall-mounted heat pump, we recommend:
- Cleaning filters every 4 to 6 weeks
- Visual inspection of the outdoor unit
- Maintaining clearance around the unit
- Annual professional inspection

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.
