As part of a recent residential project in Rosemont–La Petite-Patrie , our AirGreen team completed the installation of a Gree Charmo wall-mounted heat pump , a perfect choice for the brick buildings typical of this Montreal neighbourhood. This type of building, often composed of stacked apartments with limited ground-floor access, demands a rigorous approach from both a technical and aesthetic standpoint.
A dense Montreal neighborhood that requires specific technical choices
Rosemont–La Petite-Patrie is known for its urban density , brick facades, and multi-story buildings. For this project, the outdoor unit had to be installed high up, securely attached to the wall, to comply with ground space and clearance requirements. This configuration is very common in central Montreal neighborhoods, where every detail counts to ensure safety, compliance, and durability.
Type of system installed: wall-mounted heat pump
We installed a wall-mounted heat pump (mini-split) , a system particularly popular in Montreal condos and multi-unit buildings. This type of unit allows you to:
-
efficient heating in winter ,
-
efficient air conditioning in summer ,
-
precise temperature control by zone,
-
a minimally invasive installation, without ducts.
The Gree Charmo fits perfectly into this category, offering an excellent balance between energy performance, reliability and acoustic comfort.
Brand and model: Gree Charmo
The Gree Charmo is a wall-mounted heat pump renowned for its proven technology and its ability to adapt to the Quebec climate. While several capacities are available to suit different needs (generally 9,000 to 24,000 BTU), this line is designed to offer:
-
excellent energy efficiency ,
-
stable operation during temperature variations,
-
ideal compatibility with wall installations in urban environments.
In this project, the choice of model was made to meet the specific needs of the housing, taking into account the surface area, orientation and insulation of the building.
Visible installation details and protruding elements
Several technical elements clearly stand out from this installation:
-
High-level wall-mounted outdoor unit , fixed on a robust galvanized steel support, freeing up floor space and reducing risks related to snow and ice accumulation.
-
Vertical routing of refrigerant lines , carefully concealed in a dark pipe cover , ensuring a clean and harmonious visual integration with the brick.
-
The cache's "Z" pattern , typical of multi-story installations, demonstrates a precise adaptation to the configuration of existing windows and openings.
-
Dedicated outdoor electrical box , installed near the unit, compliant with the standards in force in Quebec.
-
Careful management of cables and conduits to preserve the aesthetics of the facade, an essential point in a residential area like Rosemont.
Four-season comfort, designed for Montreal's climate
Installing a Gree Charmo wall-mounted heat pump in Montreal means choosing a system that ensures consistent comfort year-round . In summer, the wall-mounted unit maintains a pleasant temperature, even during urban heat waves. In winter, the heat pump efficiently contributes to heating, reducing reliance on traditional electric systems and helping to control energy costs.
Why entrust this type of project to AirGreen?
At AirGreen , we specialize in residential HVAC installations in Montreal, Laval, and on the North and South Shores. Our approach is based on:
-
a precise analysis of the building and the neighborhood ,
-
technical solutions adapted to urban realities ,
-
meticulous execution, both mechanically and aesthetically,
-
strict adherence to electrical and safety standards.
Each installation is designed to integrate naturally into the existing environment, while offering optimal performance and long-term peace of mind.
An ideal solution for Montreal's brick buildings
This project in Rosemont–La Petite-Patrie perfectly illustrates how a Gree Charmo wall-mounted heat pump can be efficiently installed in a dense urban environment, without compromising performance or the building's exterior appearance. It's a modern, reliable, and sustainable solution for homeowners looking to improve their indoor comfort while increasing their property value.
