In Rosemont–La Petite-Patrie, many buildings are constructed of brick, and the homes are designed for specific comfort levels without the need for extensive ductwork. This is precisely the context for this AirGreen installation: a Zephyr wall-mounted heat pump (mini-split) designed to provide air conditioning in the summer and efficient heating during Quebec winters, all while remaining discreet and well-integrated into the facade.
The photo clearly shows the Zephyr outdoor unit mounted on wall brackets above ground level on a brick wall , under an eave . This type of installation is very popular in Montreal, particularly for protecting the equipment, minimizing its footprint, and maintaining easy access for maintenance.
Why a Zephyr wall-mounted heat pump in Rosemont?
Rosemont is a vibrant neighborhood: limited spaces, close neighbors, compact backyards, and sometimes location constraints (balconies, passageways, landscaping, shared entrances). In this type of environment, a wall-mounted heat pump is often the most efficient solution because it:
-
Offers room-by-room control (stable comfort, without overheating)
-
Reduces reliance on supplementary heating
-
Improves energy efficiency, especially during the mid-seasons
-
Avoids the heavy work associated with a central system (ducts)
With Zephyr , we aim for a reliable and simple system, perfectly suited to Montreal residential use, while maintaining a good balance between performance, noise and durability.
Type of system installed
This is a wall-mounted heat pump (mini-split / wall unit) .
In practical terms, this means:
-
An indoor unit (not visible in the photo) that distributes the conditioned/heated air.
-
A Zephyr outdoor unit (visible), which contains the compressor and the heat exchanger
-
Refrigeration lines (insulated piping) connecting the inside and outside
-
A condensate drain (water management) and a dedicated power supply
Model
The exact model is not legible/identifiable in the photo. In this case, we are deliberately being consistent and cautious: it is a new generation Zephyr wall-mounted heat pump , typically installed in configurations ranging from 9,000 to 24,000 BTU depending on the size, orientation, and insulation. At AirGreen, sizing is always based on the actual needs of the home (and not "by guesswork").
Observable installation details (and why they matter)
1) Outdoor unit on wall brackets (elevation)
Wall mounting on brackets is an excellent choice in Montreal:
-
Protection against snow and slush : In winter, a ground-mounted unit can be buried or suffer from ice buildup. Raised off, it breathes better.
-
Safer drainage : defrost water flows away without creating a permanent puddle at the base.
-
Maintenance made easy : direct access for inspection, cleaning, service.
-
Less vibration transmitted to the ground : when the installation is done properly (with insulation), resonance is reduced.
In the photo, you can also see blue elements at the fixing points, used to secure and stabilize the installation (and, depending on the configuration, help to limit vibration).
2) Location on a brick wall: solid, but must be treated properly
Brick is common in Rosemont. However, a permanent installation is not simply a matter of "screwing into the wall":
-
Fixings and anchors suitable for masonry
-
Perfect level of unity for internal mechanics
-
Respect the clearances around the fan
-
Proper management of pipe installation (drilling, sealing, finishing)
At AirGreen, we pay particular attention to the sealing of the penetration point: it is a detail that prevents water infiltration, unwanted air and long-term problems.
3) Installation under the eaves: a good compromise
Being under the eaves can offer additional protection against direct rain and ice. The important thing is to maintain:
-
Sufficient clearance above and to the sides
-
Optimal air circulation for heat exchange
-
Easy access to the service
What this configuration offers the customer (comfort + performance)
Summer comfort: stable, quiet, precise
A properly sized wall-mounted heat pump allows you to:
-
A stable temperature , without harsh cycles
-
A more uniform feeling of comfort
-
Proper humidity management in air conditioning (depending on usage and configuration)
Winter heating: a real plus in Quebec
In Montreal, heat pump heating is very cost-effective in the fall, spring, and often for a good part of the winter. The system adjusts its output and maintains continuous comfort, which helps reduce the use of more expensive heating sources.
The technical points that AirGreen systematically checks
Even if the installation looks "simple" in photos, a high-performance wall-mounted heat pump relies on meticulous execution. During our installations, we specifically verify:
-
Sizing (BTU) based on the dwelling: surface area, insulation, orientation, windows, lifestyle
-
Location of the outdoor unit : noise, clearance, access, winter protection
-
Quality of the refrigeration connection : insulation, routing, sealing, vacuuming
-
Electricity : suitable circuit breaker, compliant cable, appropriate protective devices
-
Condensate management/defrosting : prevent water and ice buildup in unwanted areas
-
Finish : clean, discreet, aesthetically pleasing installation (particularly important on brick facades)
Common mistakes we avoid (very common in Montreal)
In many service interventions, we consistently encounter the same problems caused by shoddy installations. Here's what we warn about from the outset:
-
Outdoor unit too low → snow / ice / air blockage
-
Insufficient clearance → loss of performance, overheating, wear
-
Poorly insulated connections → condensation, loss of efficiency
-
Unsealed drilling → water/air infiltration
-
Poorly secured supports → vibrations, noise, movement
-
Incorrect sizing → discomfort, short cycles, higher bill
Recommended maintenance to keep the Zephyr in top condition
To maintain performance and longevity:
-
Clean/maintain the indoor unit filters regularly (simple and essential)
-
Keep the outdoor unit clear (of leaves, dust, snow)
-
Schedule periodic inspection/maintenance: general check, cleaning, pressure checks and component condition assessment.
A well-maintained system is quieter, more efficient, and more durable.
Conclusion: a clean, robust installation adapted to Rosemont
This Zephyr installation exemplifies a distinctly Montreal approach: maximizing comfort while respecting the building's actual constraints. The wall-mounted installation on supports , on brick , with a raised unit under the eaves, is a smart choice for performance, accessibility, and winter protection.
At AirGreen, we always aim for the same goal: a solid , aesthetic installation, optimized for the climate of Greater Montreal — so that the heat pump works well, for a long time, and economically.
