In Chomedey, Laval , AirGreen installed a Zephyr wall-mounted heat pump (mini-split) in a very common condominium setting: a unit with a balcony/gallery and clear constraints regarding noise, aesthetics, and space. The objective was simple: to ensure year-round comfort (heating and cooling) while maintaining a clean, safe, and durable installation, despite a semi-sheltered and shared outdoor environment.
System type: Zephyr wall-mounted heat pump (residential mini-split)
The photo shows the outdoor unit (condenser) of a wall-mounted/mini-split system, typically connected to one or more indoor units. This project illustrates an ideal residential configuration for a condo or apartment:
-
Precise temperature control
-
Efficient heating in mid-season and winter
-
Stable air conditioning in summer
-
Discreet operation , essential in buildings
Model: Zephyr wall-mounted "new generation" (visual identification)
The model number is not legible in the image, but the format and design correspond to a recent Zephyr wall-mounted heat pump , designed for urban installations where good performance, efficient modulation and simple integration are desired (covered refrigerant lines, clean electrical connection).
In this type of configuration, we very often talk about a typical residential capacity (e.g. 12,000 to 18,000 BTU), sized according to the area, sunlight, insulation and room layout.
Key installation details: what makes the difference on a balcony
1) Outdoor unit on a raised support: protection + durability
The Zephyr unit is installed on a raised metal support , a strategic choice in a condominium:
-
reduces exposure to groundwater and waterlogging,
-
facilitates maintenance (clearing, cleaning, inspection),
-
improves longevity by avoiding direct contact with wet surfaces.
2) Semi-sheltered environment: excellent for the machine… provided that clearances are respected
A metal roof/awning is visible above the gallery. This is an advantage (protection from the elements), but it requires careful installation:
-
sufficient clearance for air intake and exhaust,
-
positioning that avoids recirculation,
-
location designed to maintain stable performance, even during large temperature variations.
3) Vibration and noise management: essential in buildings
In condominiums, noise acceptability is a major factor. Our AirGreen approach systematically includes:
-
Solid stabilization on a base
-
vibration reduction (clean assembly, anchoring, leveling),
-
positioning that limits transmission to the structure and the surrounding area.
4) Connections and finishing: clean and safe vertical route
The pipes and cables follow a well-organized vertical path, typical of a carefully installed system:
-
mechanical protection of the connections,
-
More discreet finish (important in a condominium).
-
reduction of the risk of snagging and premature wear.
5) Outdoor electrical box: access, maintenance and compliance
An electrical box (disconnect/connection switch) is visible nearby. This is an often underestimated but crucial detail:
-
Quick access for maintenance,
-
safety during interventions
-
cleaner installation that complies with best practices.
Why this installation works so well for Laval (and Greater Montreal)
In Laval, as throughout Greater Montreal, the reality is: humidity, freeze/thaw cycles, rapid temperature changes, and intensive use in both summer and winter. A Zephyr wall-mounted heat pump, properly installed on a balcony, means:
-
consistent comfort in the main rooms
-
a very effective solution when interior space is limited,
-
an integration that respects the constraints of the building,
-
a system designed to last, not just to “work on day 1”.
Conclusion: a Zephyr on a balcony, installed with care
This project in Chomedey perfectly illustrates what we strive for at AirGreen: a high-performance Zephyr wall-mounted heat pump , installed in a confined space, with meticulous attention to the details that matter in a condominium (mounting, clearances, finish, noise, safety). The result: a clean, efficient installation, perfectly suited to everyday life.
