A compact and neat installation in a very restricted outdoor space in Senneville
In Senneville, this installation of a FUJITSU ORION XLTH+ 15,000 BTU wall-mounted heat pump perfectly illustrates the type of project where field experience makes all the difference. The client was looking for a reliable solution to improve their four-season comfort, with a machine capable of effectively heating in the harsh Quebec winter, while maintaining a clean, safe, and discreet outdoor installation.
The choice fell on the FUJITSU ORION XLTH+ 15,000 BTU, a wall-mounted mini-split known for its cold climate performance, quiet operation, high energy efficiency, and eligibility for the provincial LogisVert subsidy. In a residence like this, located in a peaceful residential area of the West Island, the challenge was not just to install a high-performance machine: it was also necessary to contend with a cramped space, a mixed brick and siding facade, the proximity of an electricity meter, a side fence, and clearance requirements.
An HVAC project where every detail counted from the first visit
During our evaluation, we quickly realized that the available outdoor space required precise planning. The outdoor unit had to be installed near the side wall, in a narrow area between the house and the fence. This type of configuration demands particular attention for several reasons: air circulation around the unit, future access for maintenance, protection against snow accumulation, refrigerant line routing, condensate drainage, and visual integration.
At AirGreen, we never consider an HVAC installation as a simple mechanical operation. A high-performance wall-mounted heat pump can lose some of its efficiency if it is poorly positioned, not properly leveled, or if its lines are installed without a logical service plan. Here, our goal was clear: to offer the client a robust, clean, and durable installation, without compromising accessibility or the external appearance of the property.
Why the FUJITSU ORION XLTH+ 15,000 BTU was a perfect fit for this residence
The installed model, the FUJITSU ORION XLTH+ 15,000 BTU, is particularly well-suited for homes in Senneville, Montreal, Laval, Longueuil, the North Shore, and the South Shore, where temperature fluctuations can be significant between seasons.

For this house, the client wanted a solution capable of heating efficiently without constantly relying on electric baseboards. The FUJITSU ORION XLTH+ perfectly meets this need, particularly thanks to its ability to maintain reliable heat output during periods of intense cold.
An elevated outdoor installation to better face winter
One of the visible elements of this installation is the positioning of the outdoor unit on an elevated metal stand. This detail is important in the Montreal region, and even more so in residential areas where snow can quickly accumulate along walls.
Installing the unit too close to the ground is a common mistake. In winter, snow, ice, and defrost water can impair the heat pump's operation, obstruct airflow, or accelerate the wear of certain components. Here, we installed the unit at an appropriate height, with a stable, well-leveled base adapted to the unit's weight.
This choice allows:
- to limit the risks of snow accumulation around the fan;
- to facilitate water drainage during defrost cycles;
- to maintain better accessibility for maintenance;
- to reduce vibrations transmitted to the structure;
- to ensure a more durable installation in the Quebec climate.
The stand was fixed and adjusted so that the unit remains perfectly stable. This stability is essential for the proper functioning of the compressor and to avoid unwanted noise over the years.
A delicate integration near the electricity meter
A peculiarity of this project was the proximity of the electricity meter and the service mast. This configuration requires a very orderly installation, both for visual appearance and for safety.
Our technicians planned the routing of refrigerant lines and wiring to avoid any interference with existing electrical installations. The result is clean: the lines are grouped, protected, and directed logically towards the outdoor unit. The heat pump's positioning respects the available space without obstructing access to equipment already present on the wall.
In this type of installation, improvisation must be avoided. A poorly oriented line, an overly exposed cable, or an incorrectly calculated distance can complicate future interventions. Our team therefore prioritized a simple, clear, and easy-to-inspect configuration.
Line protection and exterior finish
On the facade, the lines pass through an area where brick, exterior siding, and electrical equipment meet. To preserve the finish and protect the components, we paid particular attention to the routing of the lines.
The refrigerant lines were carefully installed, properly insulated, and protected against friction. The goal was to avoid unnecessary bends, mechanical stresses, and weak points that could impair the system's long-term performance.
A successful mini-split installation is often recognized by what is not immediately noticed: absence of hanging cables, well-aligned unit, clean lines, respected clearances, subtle finish. In this project in Senneville, the space constraint made these details even more important.
Heating performance: a concrete advantage for Senneville winters
The Senneville area is exposed to sometimes harsh winter conditions, with cold winds and nights where temperatures drop well below -20 °C. For a homeowner, choosing a wall-mounted heat pump that only works in mild weather is not enough. A machine that continues to deliver heating when it's really needed is essential.
The FUJITSU ORION XLTH+ 15,000 BTU is designed to provide heating down to -30 °C, making it particularly relevant for residences in the West Island, as well as for Montreal, Laval, Longueuil, the North Shore, and the South Shore.
In practice, this type of appliance often reduces the use of auxiliary systems, especially when the installation is properly sized. The Inverter compressor adjusts its power according to actual demand, which improves comfort and limits abrupt start-stop cycles.
For the client, this translates into more stable heat, fewer temperature variations, and better management of electricity consumption during the cold season.
Efficient and quiet summer comfort
Even though heating was a high priority, air conditioning also remained an essential criterion. With a 15,000 BTU cooling capacity, this wall-mounted air conditioner is perfectly suited for a main living area, a large living room, an open-concept space, or a well-configured floor.
The indoor sound level, as low as 26 dB(A), allows for comfortable daily use. In a family home, the noise of an appliance can become irritating if the model is poorly chosen or poorly installed. Here, the FUJITSU ORION XLTH+ offers gentle, stable, and discreet ventilation.
Its SEER2 of 28.7 also helps reduce consumption during the summer. For owners who use their air conditioning several hours a day during heatwaves, this seasonal efficiency represents a real advantage.
R-32 Refrigerant: current and efficient technology
The installed system operates with R-32 refrigerant, an increasingly used option in high-performance residential HVAC equipment. This refrigerant offers good thermal efficiency and is part of a transition towards more responsible solutions than older generations of gases.
For AirGreen, the use of R-32 requires a rigorous installation: vacuum pulling, connection verification, adherence to manufacturer procedures, and precise commissioning. A high-end heat pump deserves an execution of the same standard. This is why every step was carried out methodically, from line routing to final startup.
Commissioning and final checks
Once the mechanical installation was complete, our team carried out the necessary checks before handing over the system to the client.
We particularly validated:
- the tightness of the connections;
- proper vacuum pulling;
- the stability of the outdoor unit;
- adequate drainage;
- heating operation;
- air conditioning operation;
- communication between the indoor and outdoor units;
- remote control response;
- basic system configuration;
- usage and maintenance instructions.
This step is essential. A wall-mounted heat pump installation does not end when the appliance is fixed to the wall. Commissioning confirms that the system is operating under the right conditions and that the client knows how to use it effectively.
Mistakes to avoid in a similar installation
This project in Senneville reminds us of several common mistakes we sometimes see during inspections or replacements of old systems.
The first mistake is to install the outdoor unit too low. In our climate, this can lead to ice, ventilation, and defrosting problems. The second is to neglect service access. A unit placed too close to a fence or an obstacle can become difficult to maintain. The third is to improperly protect the lines, especially when they pass near other outdoor equipment.
It is also important to avoid choosing a machine based solely on price. A wall-mounted heat pump must be selected according to the area, insulation, orientation of the house, lifestyle habits, and heating expectations. An undersized unit will run at full capacity too often. A poorly positioned unit will distribute air unevenly. A good model installed without precision will rarely deliver its full performance.
Why this installation truly represents the AirGreen approach
This project reflects our way of working: choosing the right appliance, analyzing the real constraints of the building, protecting the aesthetics of the house, and delivering a reliable installation.
At AirGreen, we carry out installations of wall-mounted heat pumps, mini-splits, and wall-mounted air conditioners throughout Greater Montreal, including Senneville, Montreal, Laval, Longueuil, the North Shore, and the South Shore. Each property has its specificities: old brick houses, recent condos, duplexes, triplexes, suburban houses, confined spaces, narrow yards, electrical constraints, co-ownership rules, or aesthetic requirements.
In this specific case, the client needed a high-performance solution without turning the exterior of the house into a visible construction site. The result is a compact, stable, clean, and locally climate-adapted installation.
An investment eligible for the LogisVert subsidy
The FUJITSU ORION XLTH+ 15,000 BTU is eligible for the provincial LogisVert subsidy for eligible projects, with assistance potentially reaching $1,296 depending on applicable conditions. For many clients, this subsidy strongly influences the decision, as it improves the return on investment of a highly efficient system.
Our role also involves guiding the client through understanding the criteria: eligible model, AHRI number, detailed invoice, compliant installation, and necessary documentation. A good HVAC installation must be accompanied by clear information, especially when financial aid programs are involved.
A discreet, efficient, and durable final result
The final result in Senneville is a FUJITSU ORION XLTH+ 15,000 BTU heat pump neatly installed in a narrow space, on an adapted bracket, with well-organized conduits and a sober exterior finish. The outdoor unit is accessible, stable, and sufficiently clear to operate efficiently.
The client now benefits from a system capable of heating in winter, air conditioning in summer, and providing constant comfort with excellent energy efficiency. This is exactly what we look for in a successful installation: a solution that works well from day one and remains reliable season after season.
For homeowners in Senneville, the West Island, Montreal, Laval, Longueuil, the North Shore or the South Shore, this project demonstrates that a wall-mounted heat pump installation can be both technical, aesthetic, and perfectly adapted to the building's constraints.
At AirGreen, we believe that a good HVAC system starts with a good analysis, is confirmed by careful installation, and is followed by accessible after-sales service. This achievement is an excellent example.
