In this typical Plateau-Mont-Royal triplex, with its exterior metal staircase and sunken backyard, the owners wanted to enjoy year-round comfort without cluttering the interior or compromising the building's aesthetics. They chose to install a Gree wall-mounted heat pump to efficiently heat and cool their apartment while reducing their energy consumption.
A Gree wall-mounted heat pump adapted for Montreal plexes
The project consists of a state-of-the-art Gree wall-mounted heat pump , a mini-split system ideal for Montreal apartments. This type of installation offers:
-
High-performance air conditioning during summer heatwaves.
-
An efficient supplementary heater for autumn, spring and a good part of winter.
-
Very low noise level, both inside and in the courtyard.
-
High energy efficiency thanks to inverter technology.
Although the exact model is not visible in the photo, we are here in the range of Gree high-efficiency wall-mounted heat pumps , designed for the Quebec climate and compatible with the requirements of many energy efficiency programs.
Strategic positioning of the condenser on a wall bracket
The photo shows the Gree condenser installed on a foundation wall, right next to the entrance to the basement or garden-level apartment. We chose a wall-mounted installation rather than a floor-mounted one for several reasons:
-
Protection against snow and ice : by being elevated, the unit remains clear even during the heavy accumulations typical of Montreal winters.
-
Improved longevity : the device is not in direct contact with water, mud or gravel.
-
Ease of maintenance : technicians can easily access the unit for annual maintenance or service checks.
The supports are securely fixed in the concrete structure, with anti-vibration blocks under the heat pump legs to minimize the transmission of vibrations to the building and to the nearby metal railing.
Air circulation and clearances respected
Despite the presence of the staircase and balcony above, the Gree unit benefits from sufficient clearance for air circulation :
-
The front of the condenser is completely unobstructed, allowing the fan to freely circulate outside air.
-
The sides and top comply with the minimum distances recommended by Gree to avoid the recirculation of hot or cold air.
-
The chosen location avoids blowing directly towards the neighbors or towards the relaxation areas of the yard.
This thoughtful positioning ensures stable performance in both summer and winter , while respecting the peace and quiet of the occupants and the neighborhood.
Discreet routing of refrigerant lines and drain
The refrigerant lines (insulated copper pipes) and communication wiring run directly to the indoor unit through the wall behind the condenser. We used a rigid protective cover to:
-
Protect the pipes against UV rays, shocks and freeze/thaw cycles.
-
Give a clean and uniform appearance to the technical passage on the facade.
The condensate drain is designed to evacuate the water produced in air conditioning mode away from the pedestrian walkway, thus preventing water accumulation and ice on the ground.
A harmonious integration into the backyard
In the alleys and backyards of Plateau-Mont-Royal, space is often limited and shared: stairs, balconies, recycling bins, outdoor furniture… Our challenge is to find a location that respects the lives of the occupants while respecting the technical constraints of the heat pump.
Regarding this project:
-
The unit remains visually discreet , neatly aligned under the balcony structure.
-
It does not obstruct passage or access to the door.
-
The noise is minimized, which is appreciated for enjoying the courtyard in the summer.
Our AirGreen sticker applied to the condenser housing clearly identifies the installer and facilitates service tracking for customers.
Performance and comfort for Montreal winters
The Gree wall-mounted heat pump installed here is designed to operate reliably for much of the Montreal winter:
-
The variable speed compressor adjusts its power according to the actual heating demand, which reduces electricity consumption.
-
Defrost cycles are managed automatically to maintain a good level of performance even in wet and cold weather.
-
In summer, the air conditioning and dehumidification modes ensure constant comfort, preventing the air from feeling heavy in the home.
Homeowners thus benefit from four-season comfort , with a better-controlled energy bill than with window devices or electric baseboard heaters used alone.
