The article, chapter by chapter
In the Southwest, you often find spaces with a more "loft-like" style: dark ceilings, pendant lights, bare walls, and minimalist furnishings. This is exactly the kind of environment where a wall-mounted heat pump must be carefully installed, both for performance and aesthetics. At AirGreen , we installed a CanAir indoor unit (wall-mounted) positioned high up in this space to optimize air distribution and maintain a discreet and clean look.
An ideal solution for comfort in both summer and winter
A CanAir wall-mounted heat pump is very well suited to the typical needs of residential spaces and small premises:
-
Effective cooling during Montreal heat waves
-
Comfortable heating during cold periods (with stable and pleasant regulation)
-
Precise temperature control for improved everyday comfort
-
Quick answer : you feel the effect of the air conditioning or heating quickly after starting.
When the goal is to have constant comfort without heavy ductwork, the wall-mounted unit often remains the best compromise: efficient, reliable, and relatively quick to install.
Choosing the location: performance + visual integration
In the photo, the CanAir indoor unit is installed near the ceiling , on a clear wall, in a space where it's important to avoid cluttering the room. This positioning has several advantages:
-
Better airflow range : higher up, diffusion occurs more naturally in the occupied area.
-
More consistent comfort : we limit areas that are too hot or too cold.
-
Aesthetics preserved : the unit remains visible (as expected), but is properly integrated into the decor, without cutting off the space or harming the atmosphere.
In this type of environment, attention is also paid to details that change everything: alignment, the perfect level of the unit, the distance from obstacles (light fixtures, corners, wall returns), and the behavior of the airflow to avoid direct drafts.
Prominent installation details observable
Even though the exterior (condenser) is not visible here, certain elements of the internal installation are clearly visible:
-
High and stable mounting , ideal for good air circulation.
-
Discreet routing of pipes : the right side of the unit suggests a well-planned passage (often behind the wall or via a neatly finished side exit).
-
Integration into a space with a dark ceiling : this type of ceiling requires particularly careful installation, as the slightest visual imperfection is noticed more quickly (shadows, contrasts, lines).
And of course, a complete and durable installation also involves (even if it is not visible in the photo): well-managed condensate drainage , proper sealing at the point of penetration, and functional tests (pressure, tightness, drainage, efficiency).
Model: consistent, without overpromising
The exact model isn't visible in the photo. In this case, we correctly present it as a new generation CanAir wall-mounted heat pump , chosen to offer a good balance between comfort, efficiency, and reliability , without inventing unverifiable specifications.
If you have a photo of the nameplate (often on the side or under the cover), we can precisely identify the reference — but the installation itself remains perfectly describable and consistent with what we see.
Why is this type of installation popular in the Southwest?
The Southwest (including Griffintown and its surroundings) often combines open spaces, large rooms, hard materials (concrete, drywall, smooth surfaces), and a minimalist design aesthetic. Wall-mounted heat pumps are particularly well-suited to this style because they:
-
avoids pipework,
-
offers a solution that is quick to deploy.
-
integrates into unobstructed walls,
-
allows for room-by-room control (depending on the configuration).
Our AirGreen approach: clean, sustainable, and customer-centric
At AirGreen, our priority is simple: a clean , reliable installation, optimized for the real comfort of the occupants. That means:
-
a well-considered location (not just "where it fits"),
-
a concern for the finishing touches.
-
a complete commissioning,
-
and clear explanations for use and maintenance.
If you are considering a CanAir wall-mounted heat pump in Montreal (or on the North Shore / South Shore / Laval), we can recommend the most logical configuration based on your space, habits, and comfort goals.
The job tools
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.
How the job unfolds
The main steps of this kind of job at AirGreen. Every house has its quirks: the estimate brings them out.
We look at the room, the outside wall, the line route and where the outdoor unit will go. That is where the capacity gets chosen.
Model, capacity and price, in writing. We also check whether the model qualifies for assistance programs.
Floors and furniture protected, wall plate position marked level, wall opening located.
A single opening, with the slope the drain needs to flow outside.
Set on a stand raised above the snow, with the clearances the manufacturer requires.
Connected, insulated and protected. The opening is then sealed against water, cold air and insects.
A dedicated circuit and an accessible disconnect near the outdoor unit.
Leak test, vacuum, then start-up and a check of heating and cooling.
Remote, modes, filters: we show you the essentials before we leave.

What we check on a job like this one
Each number is a point we check on site. Switch between summer and winter to watch air and heat move.
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.
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.
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.
Good habits, once the unit is in place
Six simple habits that keep the unit going. Your list stays on this device.
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.
The right pages, at the right time
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.
