The job on one screen
The article, chapter by chapter
In urban neighborhoods like Verdun , installing a heating and air conditioning system requires navigating limited space , brick facades, and very real aesthetic constraints. This project perfectly illustrates how a Zephyr wall-mounted heat pump can be integrated cleanly, sustainably, and efficiently, while respecting the existing architecture.
Project context in Verdun
The property is located in a typical area of Verdun, with a brick facade , a rear entrance, and limited floor space. The client wanted to improve comfort in both summer and winter without a central heating system or invasive renovations. The chosen solution was to be:
-
compact,
-
performing well in Quebec's climate,
-
visually discreet,
-
installed without encroaching on the courtyard or passageways.
Type of machine installed
We installed a Zephyr brand wall-mounted heat pump (mini-split / wall unit) .
This type of system is particularly well-suited to urban housing:
-
No conduit distribution required.
-
excellent energy efficiency
-
precise temperature control in the main zone
-
silent operation.
Make and model
-
Brand: Zephyr (brand name provided manually and used as the primary reference)
-
Model: Zephyr new generation wall-mounted heat pump (exact model not visually identifiable, but consistent with a single-zone residential system)
This configuration meets the common needs of homes in Verdun: reliability, simplicity and efficiency.
Prominent installation details visible in the photo
This outdoor installation has several important technical features that make all the difference in the long run.
Wall mounting on metal brackets
The Zephyr outdoor unit is fixed directly to the wall , using robust wall brackets :
-
complete freeing up of floor space,
-
protection against water, snow and debris,
-
An ideal solution in dense urban environments.
Anti-vibration pads
Supports with shock absorbers are used in order to:
-
reduce the transmission of vibrations to the structure,
-
to limit the noise perceived inside,
-
to ensure a longer lifespan for the equipment.
Brick facade: controlled drilling and fixing
Fixing it to a brick wall requires precision and experience:
-
secure anchoring in the masonry,
-
respecting the integrity of the wall,
-
clean and durable finish.
Exposed and safe electrical connection
We can clearly distinguish:
-
an outdoor electrical disconnect switch ,
-
a protected and compliant food supply
-
easy access for maintenance and future interventions.
These are details often invisible to the customer, but essential for safety and compliance.
Why this type of installation is ideal in Verdun
In a neighborhood like Verdun, wall-mounted heat pumps offer several tangible advantages:
-
Perfectly suited for duplexes and townhouses,
-
no loss of floor space,
-
quick installation compared to a central system
-
immediate comfort with air conditioning in summer and supplementary heating in winter.
Performance and everyday comfort
With a properly installed Zephyr wall-mounted heat pump:
-
The temperature is more stable.
-
Heat variations are reduced,
-
the system operates in a progressive manner (inverter),
-
Comfort is significantly improved without excessive noise.
This is exactly what many homeowners in Montreal are looking for.
Maintenance and durability
To preserve system performance:
-
Keep the outdoor unit clear (of snow, leaves, ice).
-
periodically check the condition of the wall brackets,
-
clean the filters of the indoor unit,
-
Schedule periodic preventative maintenance.
A well-done installation from the start greatly facilitates future maintenance.
Conclusion: a well-designed urban installation by AirGreen
This Zephyr wall-mounted heat pump installation in Verdun demonstrates that it is entirely possible to combine performance, discretion, and durability , even in a challenging urban environment. Thanks to a solid wall mount, a secure connection, and careful integration into the brick facade, the client now enjoys year-round comfort perfectly suited to Montreal's conditions.
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.
