Installation of a Zephyr wall-mounted heat pump in Villeray–Saint-Michel–Parc-Extension (Montreal)
In Villeray–Saint-Michel–Parc-Extension, AirGreen installed a Zephyr wall-mounted heat pump with a raised wall bracket, vibration isolation, and neat electrical routing. A discreet, high-performance solution perfectly suited to Montreal winters.
Take a tour of the installation
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.
In a neighbourhood like Villeray–Saint-Michel–Parc-Extension , where brick duplexes and compact backyards abound, installing a heat pump requires as much technical precision as common sense… and a real attention to aesthetics. At AirGreen , we love this type of project: we have to optimize the location, minimize noise and vibration, facilitate maintenance, all while ensuring reliable performance during humid summers and Quebec winters.
The photo clearly shows a Zephyr outdoor unit mounted on wall brackets, installed against a brick facade, under a structure (balcony/projection) that partially protects the equipment. This is a typical example of an "urban" installation where every detail counts.
Type of machine installed
This is a wall-mounted heat pump (mini-split) : a very popular residential system in Montreal because it offers:
-
efficient heating in mid-season and winter (depending on the range),
-
stable and comfortable air conditioning in the summer.
-
precise temperature control ,
-
Relatively quick and minimally invasive installation (no conduits).
Brand (manual truth) : Zephyr
Model : not legible in the photo — therefore we describe the installation as a new generation Zephyr wall-mounted heat pump , in a standard residential (single-zone) configuration.
What the installation reveals (visible salient details)
Even without seeing the interior, several technical elements stand out:
1) Wall mounting and floor clearance
The unit is mounted on wall brackets (with pads/insulators). This is excellent practice in Montreal:
-
It keeps the machine above the snow accumulation .
-
This reduces the risks associated with water and frost near the ground.
-
This simplifies cleaning around the unit.
2) Vibration and noise reduction
Decoupling elements (pads/isolators) are used between the support and the machine. This helps to:
-
to limit the vibrations transmitted to the masonry,
-
reduce resonance (important in brick buildings and narrow courtyards),
-
improve acoustic comfort for occupants… and neighbors.
3) Clean and protected electrical routing
We observe a conduit (duct-type) running along the wall: this is the type of finish we prefer when possible, because:
-
The wiring is better protected .
-
The image is sharp .
-
The installation remains easy to inspect and maintain .
4) Semi-protected location under a projection
Being under a balcony/structure offers an advantage: less direct exposure to rain and snow. However, we always pay attention to two points:
-
maintain good airflow (air inlet/outlet),
-
maintain easy access for maintenance and diagnostics.
Why a Zephyr wall-mounted heat pump is relevant in this context
In a Montreal apartment complex, the search often focuses on a system that:
-
It heats efficiently without "drying out" the skin like some electric solutions.
-
cools down steadily despite heat waves.
-
integrates without major construction work.
A Zephyr wall-mounted heat pump meets these objectives well, especially when installed with careful attention to mounting, clearances, and vibration control — exactly what we see here.
Our AirGreen approach to this type of project
Site analysis (before drilling)
In urban environments, outdoor location is a strategic decision. We specifically evaluate:
-
the distance of the piping (to limit losses and simplify servicing),
-
the noise impact (neighboring windows, alleyways, balconies),
-
snow and water management,
-
the strength of the wall support (anchoring and load).
Neat and durable installation
For an installation like this, our priorities are:
-
anchors adapted to the brick and the substrate.
-
precise leveling (vital for drainage and longevity),
-
vibration management ,
-
clean finishes (discreet and safe pathway).
Rigorous commissioning
A heat pump can be properly installed but poorly commissioned. We place great importance on:
-
the circuit's watertightness,
-
functional checks,
-
stability tests (heating/air conditioning),
-
usage advice for the customer (modes, temperatures, best practices).
Expected result for the client
With a properly installed Zephyr wall-mounted heat pump in an area like Villeray, the customer typically obtains:
-
immediate comfort (stable temperature, fewer fluctuations),
-
effective air conditioning even on very humid days,
-
better cost control (depending on usage and insulation),
-
a discreet system, with a clean and elevated outdoor installation.
Maintenance: the small step that protects performance
To maintain performance and prevent fouling, we recommend:
-
Clean the filters of the indoor unit regularly.
-
clear the outdoor unit (leaves, dust, snow),
-
conduct periodic professional maintenance (especially before or after peak seasons).
In urban environments (dust, alleyways, traffic), this maintenance often makes a real difference to performance and noise.
Why entrust this type of installation to AirGreen?
In Greater Montreal, a successful installation isn't just about "plugging in a machine." It's about:
-
choose a location that respects the reality of the building,
-
minimize vibrations and noise,
-
to ensure a clean and safe route,
-
to deliver a durable, easy-to-maintain result.
This is exactly the type of standard we aim for at AirGreen — and the installation visible in the photo illustrates this philosophy very well: raised wall support , stable fixing , clean finishes and consistent integration with a brick facade.
The big day, step by step
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.

What would it look like 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.

Your own project, step by step
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.
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.
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.
