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 Compact and Efficient Installation in a Sainte-Julie Residence
In this house located in Sainte-Julie, our AirGreen team installed a FUJITSU ORION XLTH+ 15,000 BTU wall-mounted heat pump, a high-efficiency mini split designed to provide reliable comfort for both heating and cooling, even during Quebec's harsh winters.
The indoor unit was installed high up, near a window, in a strategic area to ensure good air distribution towards the living space. The configuration required a clean, discreet, and safe finish, as the available space between the ceiling, the side wall, and the window opening was limited. This type of constraint is common in South Shore residences, where every inch counts for achieving a result that is both aesthetic and efficient.
The Choice of Model: FUJITSU ORION XLTH+ 15,000 BTU
The client was looking for a reliable solution to improve four-season comfort, without relying solely on electric baseboards in winter or a supplemental air conditioner in summer. The FUJITSU ORION XLTH+ 15,000 BTU emerged as a very solid option thanks to its technical features:
- Cooling Capacity: 15,000 BTU
- Heating down to -30 °C
- R-32 Refrigerant
- ENERGY STAR® and ENERGY STAR® Cold Climate
- SEER2: 28.7
- HSPF2: 13.0
- WiFi included
- Indoor Sound Level: 26 to 46 dB(A)
- Piping: 1/4 – 3/8
- Provincial LogisVert Grant: up to $1,296 for eligible projects
For a residence in Sainte-Julie, this model is particularly relevant: it offers sufficient power for an open-plan area or a main living space, while maintaining excellent energy efficiency.
Wall Mounting Near the Ceiling: Precision Required
The image of this installation clearly shows one of the most important aspects of the job: the indoor unit is placed very high, with little clearance above. In this type of situation, our team must check several elements before permanently fixing the evaporator:
- the minimum clearance required for maintenance;
- access to filters;
- the slope of the condensate drain;
- the alignment of the wall plate;
- the piping exit to the outside;
- the distance from the window and moldings;
- air diffusion in the room.
A successful HVAC installation isn't just about attaching a machine to the wall. It's about anticipating daily use: filter cleaning, access to the front panel, sound comfort, airflow direction, future maintenance, and overall appearance.
In this project, the chosen location preserved wall space while maximizing airflow reach. The unit was installed stably, straight, and well-integrated into the room, without creating excessive visual clutter.
Why a Wall-Mounted Heat Pump is Ideal in Sainte-Julie
In Sainte-Julie, as elsewhere on the South Shore, homes are exposed to significant temperature variations: hot and humid summers, cold winters, freeze-thaw periods, and sustained winds depending on the terrain's orientation. A wall-mounted heat pump like the FUJITSU ORION XLTH+ directly addresses these realities.
It allows for:
- rapid cooling of the space in summer;
- reduction of indoor humidity;
- efficient heating for a large part of winter;
- decreased use of electric baseboards;
- a more stable temperature in occupied zones;
- remote control of the system thanks to integrated WiFi.
For many homeowners, the perceived comfort changes immediately: fewer abrupt variations, fewer cold spots, less noise than an old wall-mounted or portable air conditioner.
The Role of Sizing in Performance
A common mistake is to choose a machine based solely on square footage. In reality, the proper sizing of a wall-mounted air conditioner or wall-mounted heat pump depends on several factors:
- building insulation;
- solar orientation;
- ceiling height;
- number of windows;
- floor level concerned;
- natural air circulation;
- presence of a staircase;
- room usage;
- desired comfort level.
In this Sainte-Julie project, the 15,000 BTU format offered an excellent balance between power, modulation, and efficiency. A unit that was too small would have worked too hard on very cold or very hot days. A unit that was too large could have caused short cycles, less dehumidification, and less uniform comfort.
An Installation Designed for Durability
At AirGreen, we pay particular attention to the invisible steps of installation. These are often what determine the system's reliability over several years.
Our technicians notably ensure:
- proper vacuum pull;
- protection of refrigerant lines;
- circuit leak testing;
- correct condensate drainage;
- compliance with electrical requirements;
- installation of the outdoor unit in an accessible location;
- explaining operation to the client after start-up.
In a FUJITSU mini split installation, the quality of the work is as important as the quality of the appliance. A poorly installed excellent machine can lose performance, generate noise, create drainage problems, or reduce its lifespan.
Four-Season Comfort with a Clean and Professional Finish
This project perfectly illustrates what many homeowners in Sainte-Julie, Longueuil, Montreal, Laval, the North Shore, and the South Shore are looking for: an efficient, discreet, and durable HVAC solution, installed by a team that understands the real constraints of Quebec buildings.
Reliable Heating Down to -30 °C
The FUJITSU ORION XLTH+ series is designed for cold climates. Its heating capacity down to -30 °C is a major advantage for homeowners who want to reduce their reliance on traditional heating systems.
In practice, this means the heat pump can continue to provide comfortable heat when temperatures drop sharply. For a Sainte-Julie client, this performance is particularly valuable during January and February nights, when electric baseboards can become expensive to use as a primary source.
Efficient and Quiet Air Conditioning in Summer
In air conditioning mode, the 15,000 BTU capacity effectively cools a main area of the house. The indoor sound level, as low as 26 dB(A), makes the unit very discreet for everyday use.
This is a significant advantage in a living room, home office, or family space. The unit can operate for several hours without becoming bothersome, which improves actual comfort, not just the temperature displayed on the thermostat.
WiFi Included: Simple Daily Control
The integrated WiFi allows the homeowner to control the heat pump remotely. This feature quickly becomes useful for:
- starting the heating before returning home;
- adjusting the temperature from work;
- reducing the setpoint when away;
- restarting air conditioning before a heatwave;
- checking the operating mode without moving.
For an active family or a homeowner who wants to optimize their consumption, this smart control adds real value.
LogisVert Grant: a Concrete Financial Advantage
The FUJITSU ORION XLTH+ 15,000 BTU is eligible for the provincial LogisVert grant, with assistance potentially reaching $1,296 according to applicable criteria. This grant can significantly reduce the net cost of the project.
At AirGreen, we help our clients understand the eligibility criteria and keep the necessary documents: invoice, installed model, AHRI number, proof of installation, and technical information.
Mistakes to Avoid During a Wall-Mounted Installation
This project in Sainte-Julie also serves as a reminder of several common mistakes:
Installing the unit too low
A unit placed too low can impair air diffusion and create localized discomfort.
Neglecting filter access
A device that is difficult to open will be poorly maintained. Filters must remain accessible.
Poor drain management
An incorrect slope or poorly planned drainage can cause leaks, odors, or system shutdowns.
Choosing a model not adapted for cold weather
Not all wall-mounted heat pumps are equal in winter. For Quebec, cold climate heating capacity is essential.
Prioritizing only price
An HVAC installation should be evaluated based on the quality of the appliance, the installer's expertise, the finish, after-sales service, and available warranties.
