A compact and neat installation in a very tight interior space
In Outremont, our AirGreen team installed a Fujitsu AIRSTAGE Orion XLTH+ 15,000 BTU wall-mounted heat pump, a high-efficiency mini-split system designed to provide reliable comfort for both heating and cooling, even during Quebec's harsh winters. This installation stood out due to a very specific constraint: the indoor unit had to be positioned in a narrow space, close to an existing architectural frame and a side wall, while maintaining a clean finish, good technical clearance, and efficient airflow.
The result perfectly illustrates what we aim for in every HVAC installation in Montreal: discreet, functional, durable integration adapted to the building's reality.
A Fujitsu Orion XLTH+ chosen for four-season comfort
The installed model, the Fujitsu AIRSTAGE Orion XLTH+ 15,000 BTU, is particularly well-suited to Outremont residences, where older homes, renovated condominiums, well-maintained duplexes, and interior spaces where aesthetics are as important as performance are common.
This wall-mounted heat pump offers:
- a cooling capacity of 15,000 BTU;
- heating performance down to -30 °C;
- R-32 refrigerant;
- high seasonal efficiency with SEER2 28.7 and HSPF2 13.0;
- WiFi included;
- a quiet indoor unit, as low as 26 dB(A);
- eligibility for the LogisVert provincial subsidy for eligible projects.
Precise wall installation in a delicate architectural context
In the photo, the proximity between the wall unit and existing interior elements is immediately noticeable. The device is installed above an opening, with reduced lateral clearance. This type of configuration requires much more than just wall hanging: it's necessary to validate the structure, the pipe trajectory, condensate drainage, future access for maintenance, and effective air circulation.
Our refrigeration technicians therefore paid particular attention to several elements:
- the exact positioning of the wall plate;
- the alignment of the unit with the existing frame;
- the exit of the pipes without compromising the interior finish;
- the stability of the device despite the restricted space;
- the preservation of sufficient access to filters and service panels.
In a neighborhood like Outremont, where properties often have moldings, thick frames, older walls, or partial renovations, this level of precision makes a real difference.
Why 15,000 BTU was a good choice for this project
The choice of a 15,000 BTU capacity is never random. Before an installation, we analyze the surface area, insulation, orientation, ceiling height, room layout, and usage habits. A unit that is too small would constantly work at full capacity. A unit that is too large could lead to short cycles, less dehumidification, and less stable comfort.
In this Outremont project, the Fujitsu Orion XLTH+ 15,000 BTU represented an excellent balance to ensure:
- efficient cooling in summer;
- stable heating during winter;
- good modulation thanks to Inverter technology;
- air distribution adapted to the main space;
- controlled energy consumption.
Heating down to -30 °C: a major advantage in Montreal
For a residence in Greater Montreal, a wall-mounted heat pump must be able to perform well when temperatures drop below -20 °C. The Fujitsu Orion XLTH+ is designed to maintain reliable heating capacity down to -30 °C, making it a very relevant choice for owners who want to reduce their dependence on electric baseboard heaters while maintaining stable comfort.
This model is particularly appreciated in projects where the client is looking for a serious, durable, and quiet solution, rather than a simple wall-mounted air conditioner used only during the summer.
A discreet and clean interior finish
The AIRSTAGE indoor unit features a sober design, with rounded lines and a streamlined front panel. In this installation, the unit integrates well into the existing environment despite the space constraint. The elevated position maximizes air diffusion while keeping the walls free for interior design.
Finish is important, especially in an Outremont property. A poor installation can quickly become visible: misaligned ducts, poorly placed wall outlet, unit too low, incorrect drain slope, or insufficient clearance. Here, the objective was clear: to achieve an installation that was technically sound, but also visually clean.
Mistakes to avoid in a similar installation
This type of installation may seem simple at first glance, but several errors can compromise the system's performance or durability:
- installing the unit too close to the ceiling or a side wall;
- neglecting filter access;
- underestimating the importance of drainage;
- incorrectly sizing the BTU capacity;
- using an overly complex piping trajectory;
- not performing a rigorous vacuum evacuation;
- choosing a location solely for aesthetics, without considering air circulation.
At AirGreen, we always prefer to slightly slow down planning rather than correct a poorly conceived installation afterward. A well-executed HVAC installation begins even before the tools arrive.
LogisVert Subsidy and Energy Efficiency
The Fujitsu Orion XLTH+ 15,000 BTU is eligible for the LogisVert subsidy according to the applicable project criteria. For many homeowners in Montreal, Laval, Longueuil, on the North Shore, and on the South Shore, this financial aid can make a significant difference in the net installation cost.
Beyond the subsidy, the system's energy efficiency is a strong argument. With a SEER2 of 28.7 and an HSPF2 of 13.0, this unit aims for reduced consumption in both cooling and heating. For customers who use their heat pump several months a year, this efficiency can translate into better comfort and smarter electricity use.
A quiet solution for living spaces
The indoor sound level, as low as 26 dB(A), is a highly appreciated feature. In a house or condo, a wall unit can be installed near a living room, office, or bedroom. Noise then becomes an essential criterion.
This installation in Outremont precisely met this priority: to offer a high-performance yet discreet solution. The client could enjoy four-season comfort without transforming the space into a noisy or visually cluttered area.
The Importance of a Specialized Fujitsu Team
Installing a Fujitsu mini-split requires adhering to the manufacturer's best practices: piping, fittings, electrical supply, commissioning, condensate drainage, leak tests, and functional validation. A high-end machine poorly installed will never deliver its full performance.
Our AirGreen approach is based on comprehensive execution:
- site analysis;
- location selection;
- mechanical installation;
- refrigerant connection;
- vacuum evacuation;
- electrical checks;
- heating and cooling mode testing;
- explanation of operation to the client.
It is this rigor that allows a Fujitsu wall-mounted heat pump to deliver expected performance for several years.
An installation representative of AirGreen projects in Outremont
Outremont often presents interesting challenges: meticulous interior spaces, aesthetic constraints, older buildings, sometimes limited access, high owner expectations, and the need for very clean work. This project perfectly summarizes our role: to propose a high-performance HVAC solution, but installed with respect for the building.
We regularly carry out similar installations in Montreal, Laval, Longueuil, on the North Shore, and on the South Shore, but each project requires adaptation. In this specific case, the main challenge was interior integration. In other projects, it will be the location of the outdoor unit, the pipe length, the passage of ducts, noise for the neighborhood, or the subsidy application.

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.
