As part of a recent residential project in Rosemont–La Petite-Patrie , our AirGreen team installed anElios wall-mounted heat pump in a typical Montreal urban environment. The area, known for its brick buildings, narrow backyards, and space constraints, demands a precise, discreet, and durable installation approach—exactly the kind of challenge we master every day.
A choice suited to the Montreal urban context
The building in question is a classic Montreal duplex, with a brick facade and exposed foundations. Given the limited outdoor space, the positioning of the outdoor unit had to meet several requirements: minimum clearance for ventilation, noise reduction for the neighborhood, protection against snow accumulation, and accessibility for maintenance.
The Elios wall-mounted heat pump , chosen for this project, proved to be perfectly suited to this type of dense residential configuration.
Type of system installed
This is a wall-mounted heat pump (mini-split) , a format very common in central Montreal neighborhoods, especially when buildings do not have existing ductwork or when you want to improve comfort without major work.
Why a wall-mounted heat pump?
-
Heating and air conditioning with a single unit
-
Excellent energy efficiency , even in Quebec winter conditions
-
Non-invasive installation , ideal for existing buildings
-
Precise room-by-room temperature control
Selected make and model
-
Brand : Elios (brand used as the main reference for this project)
-
Model : Elios new generation wall-mounted heat pump (R32 residential range, capacity suitable for urban housing)
Even if the exact model is not clearly displayed on the outdoor unit, the condenser's size, compactness and design correspond to a recent Elios wall-mounted heat pump , designed for cold climates and small spaces.
Observable installation details and technical choices
Outdoor installation
The outdoor unit was:
-
Mounted on sturdy wall brackets , anchored directly into the masonry
-
Raised above ground level to prevent snow and water accumulation
-
Installed against a brick wall , with sufficient rear clearance for optimal air circulation
This type of installation is common in Rosemont and similar neighborhoods, where backyards are narrow and where people want to preserve ground space.
Vibration and noise management
Anti-vibration mounts were used in order to:
-
Minimize noise transmission within the building structure
-
Improving acoustic comfort both indoors and outdoors
-
Protecting the compressor's lifespan
Visual integration
Aesthetics is an often underestimated aspect in urban environments. Here, the Elios unit integrates discreetly at the rear of the building, without altering the facade or encroaching on passageways.
Performance and everyday comfort
The installed Elios wall-mounted heat pump offers:
-
Efficient heating during Montreal winters , including periods of extreme cold.
-
Stable and quiet air conditioning during periods of summer heat and humidity
-
A significant reduction in energy costs compared to traditional electrical systems
For the occupants, this translates into constant comfort, without sudden temperature variations, and a better quality of life throughout the year.
Why AirGreen for an installation in Rosemont–La Petite-Patrie?
At AirGreen , we are intimately familiar with the realities of Montreal's central neighborhoods:
-
Access is sometimes restricted.
-
Old or partially renovated buildings
-
Noise and neighborhood constraints
-
High aesthetic standards
Our approach is based on:
-
A thorough analysis of the building prior to installation
-
Technical choices adapted to the urban environment
-
A meticulous execution , compliant with HVAC standards and best practices
Each project is treated as a unique case, with the objective of optimizing performance, sustainability and system integration.
A sustainable investment for Montreal residences
The installation of an Elios wall-mounted heat pump in Rosemont–La Petite-Patrie perfectly illustrates how a well-chosen and properly installed system can transform the comfort of an urban dwelling. Whether for a renovation, an energy upgrade, or the replacement of an existing system, this type of solution is part of a long-term vision, aligned with the real needs of Greater Montreal residents.
