The job on one screen
The article, chapter by chapter
In a modern condo in Ville-Marie , our AirGreen teams installed a Zephyr wall-mounted heat pump (mini-split) to provide consistent comfort year-round without compromising the aesthetics of the space. The challenge here was clear: to integrate a high-performance heating and cooling solution while maintaining a clean, minimalist, and harmonious interior finish.
An ideal solution for an urban condo: the Zephyr wall-mounted heat pump
The choice naturally fell on a Zephyr wall-mounted heat pump , a format particularly suited to condo-type dwellings:
-
Space saving : no loss of floor space, the indoor unit is fixed at a height.
-
Four-season comfort : air conditioning in summer, efficient heating in cold seasons.
-
Precise control : fine temperature adjustment, stability and smoothness.
-
Quiet operation : essential in an urban environment and in a condominium.
In this project, the Zephyr indoor unit was installed at the top of an anthracite grey accent wall, a choice that highlights the simplicity of the unit while ensuring optimal air distribution.
Model: a "new generation" Zephyr wall-mounted unit (residential wall format)
In the photo, we recognize a Zephyr wall head with a clean design, with a central digital display (temperature/status), typical of recent units oriented towards comfort and visual discretion.
Even though the exact model number isn't legible here, we're clearly looking at a latest-generation Zephyr residential wall-mounted heat pump , designed for:
-
to provide a rapid response to temperature variations,
-
maintain stable air (fewer variations, fewer “peaks”),
-
improve the quality of daily comfort (night mode, modulation, fine settings).
Key installation details (what you see and what it implies)
1) High positioning: better air circulation
The unit is mounted near the ceiling, which is ideal for:
-
project the air over a greater distance,
-
to promote better circulation within the room,
-
reduce areas that are “too hot / too cold”.
2) Aesthetic integration: clean and discreet installation
In a condo, appearance matters as much as performance. Here, the unit integrates seamlessly into the wall, with a minimalist visual presence. At AirGreen, our goal is always the same: an efficient installation that is also meticulous (alignment, leveling, clearances, finish).
3) Shutters and air distribution: comfort without direct drafts
The lower flap and directional louvers allow you to direct the airflow to avoid discomfort. In practice:
-
In air conditioning, the air is often directed to avoid blowing directly onto living areas.
-
In heating, we optimize the diffusion to heat evenly .
4) “Greater Montreal” context: real performance, not just on paper
In Montreal, a heat pump must be designed for real-life conditions: cold periods, rapid temperature changes, humidity, and constant comfort needs. Our approach involves sizing and installing the unit so that it operates within its optimal range , with stable performance and extended lifespan.
Our AirGreen approach: an installation that protects your comfort… and your investment
Installing a wall-mounted heat pump isn't just about "installing a unit." The final quality depends heavily on the installation. At AirGreen, we focus on:
-
a coherent choice of location (airflow, comfort, noise, aesthetics),
-
rigorous installation practices (stability, clearances, drainage, vibrations),
-
a clean commissioning process to ensure reliable performance,
-
usage tips to maximize comfort and energy savings.
The result: a Zephyr solution perfectly suited to an urban condo, offering immediate comfort, stable temperature, and impeccable visual integration.
Conclusion: a Zephyr wall light in Ville-Marie, simple, effective, elegant
This project in Ville-Marie perfectly illustrates what many condo owners in Montreal are looking for: a Zephyr wall-mounted heat pump that gets the job done without being an eyesore. A successful installation is a combination of common sense, precision, and experience—and that's exactly what we deliver, project after project.
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.
