Installation of a Canair wall-mounted heat pump in Ville-Marie (Montreal)
AirGreen installed a Canair wall-mounted heat pump in Ville-Marie in an urban space with exposed ceilings. The result: efficient air conditioning in the summer, comfortable heating in the winter, and a clean integration suitable for Montreal condos and lofts.

In summer, the outdoor unit rejects the house's heat outside.

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.
In a typical urban space in Ville-Marie , where open ceilings, exposed ductwork, and semi-open-plan rooms are common, thermal comfort can become a real challenge: stagnant heat in summer, cold spots in winter, and rapid temperature fluctuations depending on occupancy and lighting. This installation addresses precisely the needs of this space: a wall-mounted unit installed high up, with a clearly visible setpoint display (60), designed to offer precise, quiet, and efficient control.
At AirGreen , we therefore installed a Canair wall-mounted heat pump (mini-split) to ensure reliable heating and air conditioning , while respecting the aesthetic and technical constraints of a modern indoor environment.
A logical choice: the Canair wall-mounted heat pump in an urban environment
In this type of setup (exposed ceiling, visible pipes, dark walls, direct lighting), a central ducted system isn't always the simplest—or the most cost-effective—solution. A wall-mounted heat pump often remains the most efficient option for:
-
stabilize the temperature quickly,
-
to improve comfort in a main room,
-
to maintain good performance even during cold periods (depending on the configuration and range),
-
limit intrusive work.
The brand supplied for this project is Canair — and it was this brand that guided the choice of system, components and installation approach.
Observable installation details and constraints taken into account
The photo clearly shows a wall-mounted indoor unit installed very close to the ceiling, above a curtain (visually separating the space), in a setting where every element is visible. This type of placement is never "random": it aims to maximize airflow while maintaining a clean, integrated look.
Here are the key elements we took into account (and which are clearly visible visually):
1) High positioning for better airflow
Installing the wall-mounted head at a height allows for:
-
improved projection (air directed forwards and downwards),
-
a reduction of dead zones,
-
a more consistent performance in open rooms.
2) Obstacle and airflow management
The curtain under the unit is an important point: it can influence air return and diffusion if the airflow is poorly directed. We always adjust:
-
the orientation of the shutters,
-
the ventilation speed,
-
and the mode (heating/cooling/dehumidification)
to maintain efficient air circulation without unpleasant drafts.
3) “Open ceiling” environment: lines and drainage to be properly planned
With an exposed ceiling (pipes, ducts), care must be taken to:
-
the passage of the connections (refrigerant + wiring),
-
the slope and drainage of the condensation drain ,
-
the discretion of the path (to keep a clean look, especially in a visible space).
4) Aesthetic integration
The white unit stands out against a dark wall: this is common in Ville-Marie. Our approach is to maintain a clean and aligned installation, with a clean finish, because in these settings, the mechanics “are part of the design”.
Model: realistic identification without overpromising
The exact model is not visible on the unit from the photo. In this case, we remain consistent and transparent: this is a new generation Canair wall-mounted heat pump , designed for residential comfort (and condo/loft-type spaces), with precise temperature control and modulated ventilation.
Expected result: stable, fast, and energy-efficient comfort
After installation, this type of system generally provides very tangible benefits:
-
Immediate comfort : rapid temperature rise/fall, useful in urban spaces where sunlight and appliances (lighting, cooking, electronics) quickly change the thermal load.
-
Improved energy efficiency : the heat pump adjusts its power according to the actual need, instead of operating “on or off”.
-
Silence and discretion : particularly important in condos, studios, home offices or mixed spaces.
-
Simple control : a clear instruction and fine adjustment (as seen on the display).
Our AirGreen method: careful installation, real performance
When we install a Canair wall-mounted heat pump in Montreal, we don't just "stick a head to the wall." We validate the points that make a real difference in the long term:
-
Choosing the location : to avoid air short circuits, discomfort and maximize range.
-
Condensation drainage : slope, securing, prevention of backflow and odors.
-
Sealing and cleanliness of the fittings : to protect performance and durability.
-
Calibration and testing : verification of operation, modes, and air diffusion in the area.
-
Usage tips : recommended settings, maintenance, seasonal best practices.
Recommended maintenance (simple, but essential)
To maintain consistent performance:
-
Filter cleaning : ideally every 4 to 8 weeks (more often if the space is very busy).
-
Clearance around the unit : avoid obstructing the return air (curtains too close together, objects, dust accumulation).
-
Annual inspection : to check drainage, coils, performance and general condition.
A well-maintained mini-split provides more stable comfort, better air quality, and less risk of breakdowns.
Why is this type of project common in Ville-Marie?
Ville-Marie encompasses many "real" configurations: lofts, condos, small, optimized spaces, designer walls, and exposed ceilings. These environments demand an HVAC system that respects aesthetics while delivering solid performance in Quebec's climate.
This is exactly the kind of project where our AirGreen team excels: clean, efficient, sustainable , and designed for everyday use.

And at your place?
Two quick checks with real numbers: what heat costs, and what your current heaters add up to in BTU/h.
Conversion: 1 W = 3.412 BTU/h. An indication, not a load calculation: baseboards and furnaces are often stronger than the real need, and they can stay as backup. AirGreen confirms the capacity on site.
What to do, season by season
Three habits per season for this unit. They take a few minutes and prevent many calls.
- Clean the indoor unit's filters.
- Clear leaves and debris left on the outdoor unit by winter.
- Test cooling before the first hot days.
- Clean the filters more often when the unit runs a lot.
- Keep plants away from the outdoor unit.
- Check that no water drips from the indoor unit.
- Rake the leaves around the outdoor unit.
- Test heating before the first cold days.
- Book periodic maintenance before winter.
- Keep snow away from the stand and the front of the unit.
- Let the unit defrost: it is normal.
- Never hit the ice on the fins; call us if the unit stays iced up.
