For this project, our team traveled to the Plateau-Mont-Royal neighbourhood , to a typical red brick duplex with a narrow backyard. The owners wanted to replace their old air conditioning system with a four-season solution that would provide true comfort in both summer and winter, without encroaching on the ground floor circulation space. We recommended a Gree Inverter wall-mounted heat pump , perfectly suited to this type of Montreal building.
A need for air conditioning and heating in a Montreal plex
The housing presented several classic challenges of Plateau brick buildings:
-
Exterior walls that store heat in the summer;
-
Harsh winters where electric baseboard heaters struggled to keep up;
-
There is little ground space in the backyard to place a device.
The owners were looking for a system:
-
Compact, quiet and energy efficient;
-
Capable of heating efficiently at low temperatures ;
-
Easy to maintain, without obstructing passage in the alley or courtyard.
The chosen solution: a Gree single-zone wall-mounted heat pump of approximately 12,000 BTU, sized for the open-plan main floor.
A Gree Inverter wall-mounted heat pump: performance and reliability
Gree wall-mounted heat pumps are an excellent choice for Montreal plexes:
-
Inverter technology which modulates the compressor's power to maintain a stable temperature;
-
Very good energy efficiency , allowing you to reduce your Hydro-Québec bill;
-
Quiet operation, essential when the unit is close to windows or neighbors;
-
Reliable heating capacity when the mercury drops below zero.
By replacing part of the electric heating with a Gree heat pump, occupants benefit from significantly greater comfort while making long-term savings.
Carefully installed wall on brick and foundation
In the photo, you can see the Gree outdoor unit fixed to the grey foundation area of the building, just under the red brick. This placement choice is not arbitrary:
-
The galvanized steel wall bracket is securely anchored in the foundation, a more stable surface than brick;
-
The device is raised off the ground , which protects it from snow, ice and water splashes;
-
The height allows for good air clearance behind and under the unit, essential for efficiency and defrosting.
On the ground, paving slabs were laid to stabilize the area, facilitate cleaning and limit mud splashes on the device.
Visible installation details: finish and protection
Several details demonstrate the attention paid to the finish:
-
Blue anti-vibration pads under the unit's feet to reduce the transmission of vibrations to the wall;
-
Protective box for refrigeration connections and wiring, to the right of the unit, which protects the connections against the elements;
-
Passage of refrigeration and electrical connections in black sheaths securely fixed and pressed against the wall, avoiding the risk of pinching or damage;
-
Slight slope for condensate drainage , to direct water away from the foundation.
These elements, often invisible to the owner, contribute directly to the durability and quietness of the system.
Adaptation to Montreal's climate and buildings
In a narrow backyard in Plateau-Mont-Royal, performance, respect for neighbors, and architectural constraints must be combined:
-
The Gree unit is oriented to optimize airflow without blowing directly against a wall or obstacle;
-
The clearances around the fan are respected, which allows for effective defrosting in winter ;
-
Wall mounting leaves the floor free, convenient for passage, storage or maintenance work on the masonry.
Even in the coldest weather, the heat pump continues to provide efficient heating, significantly reducing reliance on electric baseboard heaters. In summer, it removes heat accumulated in the brick walls, transforming the indoor atmosphere in minutes.
Results for Plateau homeowners
Following the installation of this Gree wall-mounted heat pump, the homeowners now enjoy:
-
Four-season comfort in their accommodation, with a stable and pleasant temperature;
-
A reduction in their energy costs thanks to the excellent efficiency of Inverter technology;
-
With a discreet, solid and easily accessible outdoor installation for maintenance;
-
A building is more highly valued on the real estate market, with the presence of a modern heat pump being a major asset for future buyers or tenants.
