Generic diagram: wall-mounted heat pump, indoor and outdoor units

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.

  1. 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.

  2. The refrigerant lines, the communication cable and the drain go through the wall in a single opening, sealed against water, cold air and insects.

  3. Two insulated copper pipes connect the two units. Outside, a line cover can protect them from sun, knocks and weather.

  4. A shut-off switch near the outdoor unit isolates it safely for service. It must stay accessible at all times.

  5. The compressor and the fan. In heating mode it captures heat from the outdoor air, even in winter, and moves it inside.

  6. On the ground or on the wall, it keeps the unit above accumulated snow. The unit stays clear and defrost water can drain away.

  7. The fan needs to blow freely. Storage, a fence or a wall too close, and efficiency drops while noise goes up.

A Compact Wall Installation in a Tight Space Near the Ceiling

In Boisbriand, on the North Shore, our AirGreen team installed a Fujitsu AIRSTAGE Orion XLTH+ 15,000 BTU wall-mounted heat pump, a mini-split system designed to provide reliable heating down to -30 °C and efficient air conditioning during Quebec's hot summers.

The project presented a very concrete constraint: the indoor unit had to be installed in a small space, above a window, very close to the textured ceiling. This type of configuration requires great precision, as it is necessary to respect the necessary clearances for air intake, ensure good diffusion into the room, avoid vibrations, and maintain a clean finish despite the limited space available.

The installed model, the Fujitsu Orion XLTH+ 15,000 BTU, was particularly well suited to this Boisbriand residence due to its combination of heating performance, quiet operation, energy efficiency, and potential eligibility for the Hydro-Québec LogisVert grant for eligible projects.

A High-Performance Choice for Boisbriand's Real Climate

Boisbriand experiences the same climatic demands as many cities on the North Shore: harsh winters, frequent thaws, cold winds, humid periods, and increasingly hot summers. For this reason, a simple wall-mounted air conditioning unit is not always sufficient. Owners are now looking for a complete solution: heating, air conditioning, dehumidification, and energy efficiency.

Why the Fujitsu Orion XLTH+ 15,000 BTU was relevant here

The Fujitsu Orion XLTH+ wall-mounted heat pump offers a cooling capacity of 15,000 BTU and heating performance designed for Quebec's low temperatures. This model uses R-32 refrigerant, includes Wi-Fi, boasts high efficiency with a SEER2 of 28.7 and an HSPF2 of 13.0, and remains quiet with an indoor sound pressure level as low as 26 dB(A).

In this Boisbriand installation, these features were of particular importance:

  • stable comfort in the living area;
  • reduced reliance on electric baseboard heaters;
  • discreet operation near an occupied area;
  • reliable heating during very cold nights;
  • wall-mounted format suitable for installation above a window.

An installation near the ceiling: precision is mandatory

The project image clearly shows the reality of the site: the indoor unit is installed very close to the ceiling, in a place where every inch counts. This kind of installation should never be improvised. A wall unit placed too high, poorly leveled, or too tight against the ceiling can hinder air circulation, complicate maintenance, and increase the risk of noise or uneven performance.

At AirGreen, we paid particular attention to:

  • the perfectly straight alignment of the unit;
  • the necessary upper clearance for suction;
  • the slope of the condensate drain;
  • the clean passage of the refrigerant lines;
  • the visual finish around the window;
  • reducing vibrations transmitted to the wall.

The result is a clean, discreet, and functional HVAC installation, despite a more demanding wall configuration than average.

The challenge of positioning above a window

Installing a wall-mounted heat pump above or near a window requires serious analysis. The presence of framing, a lintel, different materials behind the wall, and sometimes limited space for conduits can complicate the work.

In this case, our team had to choose a position that would allow air to diffuse effectively into the room without being blocked by the ceiling or the window frame. We also made sure that the unit remained accessible for future HVAC maintenance, including filter cleaning, evaporator checking, and drain inspection.

A quiet wall-mounted heat pump for daily comfort

Quietness is an often underestimated criterion when purchasing a mini-split. However, a wall-mounted unit often operates several hours a day, for both heating and air conditioning. The Fujitsu Orion XLTH+ is appreciated for its discretion, making it suitable for living rooms, bedrooms, home offices, and open-plan areas.

In Boisbriand, the location near a living area made this point essential. A unit that was too noisy would quickly disturb the occupants. With this model, thermal comfort is accompanied by smooth, stable, and unobtrusive operation.

Heating down to -30 °C: a major advantage on the North Shore

The North Shore regularly experiences periods where temperatures drop below -20 °C. Choosing a standard heat pump can then become risky if the unit loses too much capacity or constantly requires supplementary heating.

The Fujitsu Orion XLTH+ 15,000 BTU is designed to provide heating down to -30 °C, making it a solid option for homeowners in Boisbriand, Blainville, Sainte-Thérèse, Rosemère, Laval, and the surrounding areas. In a well-configured home, it can significantly reduce the use of electric baseboard heaters while maintaining a more uniform indoor temperature.

R-32 Refrigerant and Energy Efficiency

This model uses R-32, a newer refrigerant than R-410A, recognized for its good thermal performance and reduced environmental impact. For homeowners, this means more current technology, better aligned with new HVAC market standards.

The system's efficiency, combined with Inverter technology, allows the unit to adjust its power according to the actual needs of the room. Instead of operating only on and off, the heat pump modulates its capacity, which improves comfort, reduces temperature variations, and limits unnecessary cycles.

An installation eligible for the LogisVert grant

The Fujitsu Orion XLTH+ 15,000 BTU model is associated with a provincial LogisVert grant that can reach $1,296, depending on applicable eligibility conditions. For many customers in Montreal, Laval, Longueuil, the North Shore, and the South Shore, this financial aid genuinely changes the final cost of the project.

At AirGreen, we support our clients by clearly explaining the important elements: indoor model, outdoor model, AHRI number, proof of installation, final invoice, and Energy Star eligibility when required.

Mistakes to avoid during a wall installation

This project in Boisbriand illustrates several common mistakes we see during replacements or corrections of poorly executed installations:

  • choosing a unit too large or too small for the room;
  • installing the unit too close to the ceiling without respecting clearance;
  • neglecting the slope of the condensate drain;
  • using a convenient location for the installer but bad for comfort;
  • forgetting future access for maintenance;
  • poorly protecting outdoor lines;
  • ignoring wall constraints above a window.

A wall-mounted heat pump installation is not limited to simply fixing a unit to the wall. Every detail influences performance, durability, and customer satisfaction.

Why AirGreen for a Fujitsu installation in Boisbriand

Our team regularly installs Fujitsu AIRSTAGE systems, wall-mounted heat pumps, mini-splits, and wall-mounted air conditioners in Greater Montreal, including Boisbriand, Laval, Longueuil, the North Shore, and the South Shore. This experience allows us to anticipate the specific constraints of Quebec homes: old walls, restricted spaces, low ceilings, poorly positioned windows, electrical constraints, and real heating needs in winter.

For this project, our priority was simple: to offer a durable, aesthetic, and high-performing installation, without compromising air circulation or accessibility.

Final result: comfort, performance, and meticulous finish

Once the installation was completed, the Fujitsu Orion XLTH+ 15,000 BTU wall-mounted heat pump integrated cleanly into the wall, above the window, while maintaining a discreet appearance. The client now benefits from a system capable of efficiently heating in winter, quickly cooling in summer, and maintaining constant comfort in the room.

This type of project represents exactly what we seek at AirGreen: an HVAC solution adapted to the building, well-sized, carefully installed, and designed to last.

For homeowners in Boisbriand and on the North Shore who wish to replace an old wall-mounted air conditioner, reduce their heating costs, or improve the comfort of a living area, the Fujitsu AIRSTAGE Orion XLTH+ 15,000 BTU remains a serious, reliable, and perfectly adapted option for the Quebec climate.

    Frequently asked questions

    What people ask us about this kind of work

    12 questions
    Does a wall-mounted heat pump heat in winter?
    Yes, it heats and cools. Its capacity drops in very cold weather; the operating range depends on the model and is listed on its spec sheet.
    Wall-mounted or multi-zone: how do I choose?
    One wall head and one condenser outside: the direct solution for a room or an open area. For two to five rooms, a multi-zone puts one head in each room on a single condenser.
    Where does the outdoor unit go?
    Where it stays above the snow, clear and accessible, away from walkways. We decide it with you during the estimate.
    Are there grants?
    Depending on the model and your situation, assistance programs may apply, including Hydro-Québec's LogisVert. AirGreen checks the model number before quoting an amount. See the grants.
    Do I need a permit?
    Rules vary from city to city: location, distances, noise. See permits and by-laws, and we check for your address.
    How cold can it heat?
    It depends on the model. According to Hydro-Québec, newer models work down to a temperature between −15 °C and −25 °C, and some cold-climate models are certified lower. The minimum temperature is on each unit's spec sheet.
    How much can I save?
    Hydro-Québec says a heat pump can be up to three times more efficient than baseboards for heating in the colder months. The result depends on the house, the climate and how it is used.
    How is the LogisVert assistance calculated?
    For ENERGY STAR cold-climate certified heat pumps, Hydro-Québec lists assistance of $120 per 1,000 BTU/h of heating capacity at −8 °C. AirGreen checks the exact model before quoting an amount; only Hydro-Québec confirms the assistance granted. See the grants.
    Is it noisy?
    The sound level depends on the model and is listed in decibels on each unit's spec sheet. Location matters too: when possible, we avoid putting the outdoor unit under a bedroom window.
    The outdoor unit is covered in ice: is that normal?
    Some frost is: the unit runs defrost cycles. Never hit the ice. If the unit stays iced up or stops heating, call us.
    Does AirGreen hold the required licences?
    Yes. AirGreen holds RBQ licence 5645-9605-01, subclasses 15.8 Ventilation, 15.10 Refrigeration and 16 Electricity.
