A Discreet and Strategic HVAC Installation in a Residential Bedroom in Deux-Montagnes
At AirGreen, we recently completed a full HVAC installation of a FUJITSU ORION XLTH 12,000 BTU wall-mounted heat pump in a residence located in Deux-Montagnes, on the North Shore. This seemingly simple project presented several technical and aesthetic challenges that our team skillfully resolved with precision.
The indoor unit was installed above a patio door, directly beneath the ceiling, in a bedroom. This configuration requires particular attention to ensure:
- optimal airflow despite ceiling proximity
- harmonious visual integration in a confined space
- maximum noise reduction for nighttime comfort
The project image clearly shows this meticulous installation: a compact unit, well-aligned, with minimal ceiling clearance while adhering to Fujitsu's technical standards.
Why the FUJITSU ORION XLTH is Ideal for Deux-Montagnes' Climate
Heating Performance Down to -26°C
In an area like Deux-Montagnes, winters are harsh. The choice of the FUJITSU ORION XLTH heat pump is not trivial. This model is designed to maintain stable performance down to -26°C, making it perfectly suited to the climatic realities of the North Shore.
Unlike standard models, this unit:
- continues to heat efficiently even in very cold weather
- reduces reliance on electric baseboards
- ensures a constant temperature without fluctuations
Inverter Technology for Stable Comfort
The integrated Inverter technology allows the machine to continuously modulate its power. This means:
- fewer on/off cycles
- reduced energy consumption
- extended compressor lifespan
In this bedroom, this translates to constant thermal comfort, especially appreciated at night.
Technical Details of the Installation Performed by AirGreen
Precise Positioning of the Indoor Unit
Installing it above the patio door presented a significant challenge:
- limited vertical space between ceiling and frame
- need to avoid a "direct draft" effect on the bed
- management of condensation and drainage
Our team carefully:
- adjusted the height to meet minimum tolerances
- oriented the louvers for optimal air diffusion
- tested drainage with a real water verification
Neatly Concealed 1/4 - 3/8 Piping
As always at AirGreen, we prioritize an impeccable aesthetic finish. In this project:
- the 1/4 - 3/8 refrigerant piping was installed with precision
- the lines were discreetly concealed
- the drillings were perfectly sealed to prevent any infiltration
Outdoor Unit Installation Adapted to Winter Conditions
Even if it is not visible in the photo, the outdoor unit was:
- elevated to prevent snow accumulation
- positioned considering prevailing winds
- installed with a robust, anti-vibration support
This type of detail is crucial to ensure the longevity of the system in the Greater Montreal area.

The FUJITSU ORION XLTH 12,000 BTU boasts impressive performance:
- SEER2: 30.5 (excellent cooling efficiency)
- HSPF2: 12.7 (economical heating)
- ENERGY STAR® Cold Climate Certification
For the homeowner in Deux-Montagnes, this means:
- significant savings on electricity bills
- efficient use all year round
- accelerated return on investment
LogisVert Subsidy of $1,200
This model is eligible for the Hydro-Québec LogisVert subsidy, offering up to $1,200 in reduction.
At AirGreen, we systematically assist our clients with:

The job tools
Two quick checks with real numbers: what heat costs, and what your current heaters add up to in BTU/h.
Baseboards and electric furnaces turn 1 kWh of electricity into 1 kWh of heat. A heat pump delivers more: that is its COP. At Hydro-Québec’s rate D (11.142¢/kWh above 40 kWh a day, since 1 April 2026):
Hydro-Québec: a heat pump can be up to three times more efficient than baseboards for heating in the colder months.
Estimate per kWh of heat, at the chosen temperature, using the certified COP from the product page. Taxes, access charge and backup heat not included.
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.

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.
