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.
A neat FUJITSU wall-mounted installation in Candiac for reliable, discreet, and efficient comfort
In Candiac, on the South Shore of Montreal, our AirGreen team recently installed a FUJITSU ORION XLTH+ 15,000 BTU wall-mounted heat pump, a high-end system designed to provide reliable heating in winter, efficient air conditioning in summer, and constant comfort in residential living spaces. This installation perfectly illustrates what many homeowners in the region are looking for: a durable, quiet, subsidy-eligible, and, above all, climate-adapted HVAC solution for Quebec's real weather conditions.
From our initial project analysis, the choice of the FUJITSU ORION XLTH+ model was obvious. The client wanted to replace a less efficient solution with a wall-mounted unit capable of heating effectively during extreme cold, while remaining visually discreet in the room. The final result, visible in the installation, shows an interior unit perfectly aligned, installed near the ceiling, with a clean finish and a subtle integration into the existing decor.
Why the FUJITSU ORION XLTH+ 15,000 BTU was a perfect fit for this Candiac home
The installed model is the FUJITSU ORION XLTH+ 15,000 BTU, comprising the indoor unit ASUH15KTAS and the outdoor unit AOUH15KTAP1. This is a mini-split wall-mounted heat pump particularly popular in Greater Montreal, especially in Candiac, Brossard, Longueuil, Saint-Lambert, Laval, Montreal, the North Shore, and the South Shore, thanks to its combination of performance, quietness, and reliability.
Its main features are particularly interesting for a Quebec residence:
- Cooling capacity: 15,000 BTU
- Heating down to -30°C
- Refrigerant R-32
- SEER2: 28.7
- HSPF2: 13.0
- ENERGY STAR®: Yes
- ENERGY STAR® Cold Climate: Yes
- Wi-Fi included
- Indoor sound level: 26 to 46 dB(A)
- Outdoor sound level: 51 dB(A)
- Piping: 1/4 – 3/8 inch
- LogisVert subsidy announced: $1,296 for eligible projects
- AHRI: 216018257
For a homeowner in Candiac, these data are not just technical. They translate concretely into a more comfortable home, better-controlled temperature, milder air conditioning in summer, and a potential reduction in reliance on electric baseboards for a large part of winter.
A wall unit installed with precision in a restricted space
The photo of this installation clearly shows one of the frequent challenges in residential projects: the available space between the ceiling, side walls, and existing architectural elements. Here, the FUJITSU indoor unit was installed very close to the ceiling, which requires precise planning to respect the necessary clearances for the device to function properly.
A wall-mounted heat pump should never be installed solely according to what "seems practical." Several factors must be taken into account:
- natural air circulation in the room;
- available height;
- access for future maintenance;
- refrigerant line path;
- condensate drainage;
- proximity to windows, doors, and heat sources;
- final aesthetics in the room.
In this specific case, our team chose a position that allows for efficient air distribution while maintaining a clean and balanced appearance. The supply vanes are clear, the unit is straight, and the visual finish meets AirGreen standards.
The right sizing: why 15,000 BTU was the logical choice
The choice of a 15,000 BTU wall-mounted heat pump must be made rigorously. A unit that is too small will constantly operate at full capacity, with irregular comfort. A unit that is too large risks having too short cycles, especially in air conditioning, which negatively affects dehumidification and comfort.
For this project in Candiac, the 15,000 BTU capacity was particularly well-suited to the space configuration. This size is often recommended for:
- an open-plan living-dining area;
- a single-family home's ground floor;
- a spacious condo;
- a space with standard ceiling and good air circulation;
- an area where supplementary heating needs to be reduced without being eliminated.
Thanks to Inverter technology, the FUJITSU ORION XLTH+ continuously adjusts its power. It doesn't simply turn on/off. It modulates according to actual demand, which allows for a more stable temperature, better-controlled consumption, and a more natural feeling of comfort.
A device designed for the winters of Candiac and the South Shore
In Candiac, winters can be demanding. Winds on the South Shore, rapid temperature variations, ice storms, and nights below -20°C require a reliable system. This is precisely where the FUJITSU ORION XLTH+ comes into its own.
With a heating capacity down to -30°C, this model is designed to maintain stable performance in conditions where many standard heat pumps begin to lose significant efficiency. For an owner, this means less reliance on auxiliary systems and better comfort during prolonged cold periods.
The model also offers excellent seasonal efficiency with an HSPF2 of 13.0, making it a relevant option for customers who want to optimize their electricity consumption. In several homes on the South Shore, we find that adding a high-performance wall-mounted heat pump allows for better heat distribution and avoids significant temperature differences between rooms.
R-32 refrigerant: a more efficient new generation
This installation uses R-32 refrigerant, which is increasingly present in new-generation residential HVAC systems. Compared to some older technologies, R-32 offers excellent thermal performance with a reduced environmental impact.
For AirGreen, this detail is important because the quality of an installation does not only depend on the choice of model. It also depends on how the system is commissioned. During our installations, we pay particular attention to vacuum pulling, sealing, pipe connections, and operational validation. A high-performance heat pump must be installed with precision to deliver its full potential.
A silent installation for daily comfort
One of the most appreciated features of the FUJITSU ORION XLTH+ is its quiet operation. With an indoor sound level that can go down to 26 dB(A), this unit is very well suited for living spaces where quietness is important: living room, home office, master bedroom, or open-plan area.
In this project in Candiac, the client wanted a high-performance appliance, but without disruptive noise. This criterion has become essential for many homeowners, especially since residential spaces often serve as living, working, and relaxation areas simultaneously.
The outdoor unit, with a sound level of approximately 51 dB(A), also remains discreet. This is an important advantage in residential areas of Candiac, where backyards and neighboring houses can be relatively close.
Wi-Fi included: simple daily control
The integrated Wi-Fi adds real practical value. The homeowner can adjust the temperature remotely, change the operating mode, prepare the house before returning, or reduce the setpoint during an absence.
In a family home, this type of control quickly becomes useful. For example, you can slightly lower the temperature during the day, then warm up the space before arriving home. In summer, it is possible to air condition gradually instead of forcing the unit to operate at full capacity upon arrival.
Technical details that make the difference during installation
A beautiful installation is not limited to placing a straight unit on the wall. Behind the final result, several technical steps determine the system's durability:
- checking the indoor location;
- choosing the conduit path;
- clean and safe drilling;
- outdoor bracket installation;
- refrigerant connection;
- compliant electrical connection;
- adequate condensate drainage;
- vacuuming;
- heating and cooling function test;
- explanation of operation to the client.
On this Candiac installation, the goal was clear: to deliver a clean, reliable, and easy-to-maintain HVAC installation. The FUJITSU AIRSTAGE indoor unit integrates discreetly into the wall, with a high position that maximizes air diffusion while preserving living space.
The importance of maintenance after installation
A high-performance wall-mounted heat pump must be well-maintained. Even the best models lose efficiency if filters, coils, or fans accumulate too much dust.
We generally recommend:
- regular filter cleaning by the owner;
- a visual inspection of the outdoor unit after storms;
- sufficient clearance around the outdoor unit in winter;
- periodic professional maintenance;
- drainage check before intensive air conditioning periods.
In Candiac, as elsewhere on the South Shore, snow, ice, and leaves can affect the outdoor unit's environment. A good installation anticipates these realities from the start.
Frequent mistakes to avoid with a wall-mounted heat pump
Many problems we observe in installations made by other contractors stem from decisions made too quickly. Among the frequent mistakes:
- choosing a capacity without calculating actual needs;
- installing the unit too close to the ceiling without respecting clearances;
- neglecting condensate drainage;
- placing the outdoor unit in a location exposed to snow accumulation;
- using a less durable exterior finish;
- forgetting future access for maintenance;
- not validating subsidy eligibility before installation.
At AirGreen, our approach is to anticipate these details before starting work. This helps avoid unpleasant surprises and deliver a lasting result.
LogisVert subsidy: an important advantage for this model
The FUJITSU ORION XLTH+ 15,000 BTU is associated with a provincial LogisVert subsidy announced at $1,296 for eligible projects. This financial aid can make the investment much more attractive, especially for homeowners replacing an old wall-mounted air conditioner or looking to reduce their electric heating consumption.
We assist our clients in understanding the eligibility criteria, required documents, and necessary technical information, such as the AHRI number, proof of purchase, and installation invoice.

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.
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.
