Installation of a Zephyr wall-mounted heat pump in Southwest Montreal
Discover a recent Zephyr wall-mounted heat pump installation in Southwest Montreal, carried out by AirGreen for optimal comfort in all seasons.
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 Montreal's Southwest borough, we recently completed the installation of a Zephyr wall-mounted heat pump in a typical urban residential setting: brick masonry, limited outdoor space, and high demands for comfort, performance, and discretion. This type of project perfectly reflects the reality of many Montreal buildings, where every installation detail matters.
At AirGreen , we support our clients from start to finish, taking into account both the constraints of the building and the specific needs of the occupants.
A Zephyr wall-mounted heat pump adapted to urban environments
The installed system is a Zephyr wall-mounted heat pump , a logical choice for urban dwellings wishing to benefit from both efficient heating in winter and effective air conditioning in summer , without heavy work on the existing structure.
The wall-mounted configuration allows for:
-
A discreet integration within the dwelling
-
High energy efficiency
-
A rapid response to temperature variations
-
Excellent compatibility with Quebec winters
Even when the exact model is not explicitly identifiable visually, the new generation Zephyr range is recognized for its reliability, stability in cold conditions and good balance between performance and cost.
Visible installation details and technical choices
Outdoor unit on a raised support
The photos clearly show that the outdoor unit is:
-
Installed on an elevated metal structure
-
Positioned near a brick wall
-
Installed on a paved surface, typical of urban courtyards or terraces
This choice is never left to chance. The raised support allows for:
-
To prevent snow accumulation in winter
-
To limit the vibrations transmitted to the building
-
To protect the device from stagnant moisture
-
To facilitate seasonal maintenance
In a dense area like Le Sud-Ouest , this type of installation also helps to preserve the aesthetics and durability of the equipment.
Managing space constraints
The limited space between walls, common in urban buildings, necessitates rigorous planning:
-
Clearances conform to manufacturer's standards
-
Optimal airflow for the condenser
-
Secure access for future maintenance
Our team systematically ensures that these parameters are respected in order to guarantee maximum longevity for the Zephyr heat pump.
Four-season comfort for Southwest residents
Thanks to this Zephyr wall-mounted heat pump, the occupants now benefit from:
-
Stable and even heating during cold periods
-
Quiet and efficient air conditioning during summer heatwaves
-
With improved energy efficiency , reducing electricity bills
-
Precise control of the indoor temperature
This type of solution is particularly appreciated in condos and plexes in the Southwest, where the aim is to modernize comfort without altering the character of the building.
Why AirGreen recommends the Zephyr wall-mounted heat pump
At AirGreen, we regularly install Zephyr systems for residential projects in Montreal, Laval, and on the South Shore. This brand fits well with our approach focused on:
-
Long-term reliability
-
Performance in cold climates
-
Compatibility with urban environments
-
Ease of maintenance
Each installation is adapted to the building, the lifestyle of the occupants and the local climatic realities.
An installation designed for Montreal's climate
Southwest Montreal combines:
-
harsh winters
-
Hot and humid summers
-
Buildings with high thermal inertia
The Zephyr wall-mounted heat pump installed here perfectly meets these conditions, offering a durable and comfortable solution, year after year.
In summary
This project perfectly illustrates AirGreen 's expertise in installing Zephyr wall-mounted heat pumps in an urban Montreal environment. Careful installation, a judicious choice of equipment, and precise adaptation to the building: that's what makes the difference.
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.
Remote, modes, filters: we show you the essentials before we leave.

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.
