Installation of a Canair wall-mounted heat pump on a brick building in Plateau-Mont-Royal
Project in Plateau-Mont-Royal: installation of a Canair wall-mounted heat pump on a brick building, with wall brackets, optimized clearances and clean pipe routing for lasting comfort.
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.
In the Plateau-Mont-Royal borough, we often work on typical Montreal brick buildings, where floor space is limited and every installation detail counts: structure, pipe routing, noise, aesthetics, safety… The photo clearly shows a dense urban context with several outdoor units mounted on the wall (a common configuration for separate dwellings). For this project, our objective was simple: to provide reliable summer/winter comfort with a Canair wall-mounted heat pump , while respecting the constraints of the building and the surrounding neighborhood.
The type of system installed: wall-mounted heat pump (mini-split)
The observed format corresponds to a wall-mounted heat pump : a compact outdoor unit (condenser) mounted on brackets, connected to an indoor wall unit by refrigerant lines. This is one of the most popular solutions in Montreal for:
-
to effectively air-condition in the summer,
-
Heating efficiently during the transitional seasons,
-
improve comfort room by room without major ductwork work.
Brand used: Canair (brand provided)
The brand installed here is Canair . On this type of project, we prioritize careful adjustments and a clean installation to get the most out of the system: stable heating, efficient defrosting in winter, and quiet operation on a daily basis.
Model: uncertain identification, consistent choice
The exact model is not clearly visible in the photo. We therefore present the installation as a Canair high-efficiency wall-mounted heat pump , in a configuration consistent with what is most often installed in buildings of this type (compact size, good performance in Quebec's climate, precise control and stable operation).
Prominent installation details visible in the photo
Several technical elements immediately stand out:
1) Wall mounting on metal brackets
The outdoor units are installed on wall brackets (robust brackets), an ideal solution in urban environments:
-
avoids clutter on the ground (backyard, passageway, alley),
-
limits the accumulation of snow around the device,
-
facilitates cleaning and maintenance.
We always ensure that the anchoring is suitable for the masonry (brick) and that the load is properly distributed to avoid any weakness over time.
2) Clearances and air circulation
A reasonable amount of clearance is observed around the units to allow for:
-
efficient air intake/exhaustion,
-
more stable operation
-
improved longevity (less air recirculation).
In the city, this is essential: a device "suffocated" by lack of space quickly loses efficiency.
3) Management of pipelines and power supply
The pipes (refrigeration and electrical) are routed along the wall , following a vertical/horizontal layout typical of multi-unit buildings. Electrical service boxes/circuit breakers are also visible near the units, a key point for safety and compliance.
At AirGreen, we pay particular attention to:
-
pipe protection (to reduce exposure to shocks and weathering),
-
the cleanliness of the path (for aesthetic reasons),
-
the positioning of the circuit breakers (for simple and safe service).
4) Urban environment: noise, vibration, neighborhood
In an area like the Plateau, comfort isn't just about temperature. The aim is also to operate discreetly.
-
vibration reduction (supports/careful installation),
-
prevention of resonance in masonry,
-
Logical layout to minimize the impact on windows and living areas.
Why this type of installation is relevant to Plateau-Mont-Royal
In brick buildings, the challenges are recurring: sometimes limited access, optimizing pipe runs, aesthetic requirements, and the need for reliability in winter. A properly installed Canair wall-mounted heat pump allows you to modernize comfort without altering the building, while also providing:
-
stable air conditioning during heat waves,
-
efficient heating for a large part of the year,
-
a noticeable improvement in everyday comfort.
Our AirGreen approach: performance, cleanliness, sustainability
On this type of project, our priority is to deliver an installation that "lasts" over time:
-
supports securely anchored,
-
clearances respected.
-
a clean and logical path of conduction,
-
rigorous commissioning (tests, functional validation, usage advice).
It is this combination (equipment + installation + fine-tuning) that makes the difference between a decent heat pump… and a truly high-performing system.
How it goes, from the first call to the end
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.

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.
