In Rosemont–La Petite-Patrie, amidst typical Montreal duplexes with stacked wooden balconies, our team installed a Gree wall-mounted heat pump to improve comfort while keeping energy costs down. The project took place in a narrow backyard, already occupied by other outdoor units: a perfect setting to showcase our expertise in space optimization.
A project in a typical Montreal backyard
The Gree outdoor unit was installed under a wooden balcony, along a concrete foundation wall. It includes:
-
A narrow passageway providing access to the rear of the building;
-
Floor tiles to facilitate maintenance and movement;
-
Other nearby mechanical equipment, belonging to other dwellings.
In this type of environment, every centimeter counts. We had to:
-
Ensure sufficient clearance for air circulation ;
-
Protect the device from snow, ice and falling objects from the balcony;
-
Limit the noise perceived in the neighborhood and in the dwellings.
A Gree Inverter R-32 wall-mounted heat pump, efficient and discreet
The owner chose a Gree Inverter wall-mounted heat pump with R-32 refrigerant , sized to heat and cool his home year-round.
Some key features of the installed system:
-
Inverter technology : the compressor modulates its power according to the actual demand, which reduces on/off cycles, increases comfort and extends the life of the device.
-
R-32 refrigerant : more energy efficient than R-410A, with a reduced environmental footprint.
-
Heating capacity adapted to Montreal's climate : the heat pump is designed to provide stable heating even in cold weather, while reducing dependence on electric or oil systems.
-
Quiet operation : the large diameter fan and the casing design limit vibrations and noise levels, an important point in a shared courtyard.
This Gree wall-mounted system allows the owner to enjoy air conditioning in the summer and efficient heating in the winter , with a single compact unit.
A wall-mounted installation, sheltered under the balcony
The photo clearly shows that the Gree outdoor unit is mounted on galvanized steel wall brackets , securely anchored to the foundation. This choice offers several advantages:
-
Elevated above ground level : the heat pump is protected against the accumulation of snow, ice and puddles.
-
Easy access for maintenance : our technicians can work under the device for cleaning and inspection.
-
Vibration reduction : Anti-vibration pads are installed under the unit's feet to prevent the transmission of vibrations to the wall and limit noise inside.
The placement under the wooden balcony is no accident. This configuration provides natural protection against direct rainfall, while leaving enough space around the heat pump for proper air circulation. We paid particular attention to:
-
At the clearance in front of the fan;
-
At the distance from the back wall;
-
Positioning relative to the other nearby outdoor unit, to avoid any recirculation of hot or cold air.
Neat electrical and refrigeration details
On the right side of the unit, one can clearly distinguish:
-
The dedicated electrical disconnect box , compliant with Code requirements;
-
The insulated and protected refrigeration pipes are neatly routed to the indoor unit;
-
The passage of communication cables, fixed and arranged to withstand the elements.
As always at AirGreen, we ensure that the installation not only complies with standards, but is also aesthetically pleasing and safe :
-
The refrigeration lines are properly insulated to prevent energy loss and the risk of condensation.
-
The cables are fixed in such a way as not to obstruct traffic or risk being torn out.
-
The disconnection box is positioned within easy reach for our technicians and any authorized personnel.
Comfort, savings and peace of mind for the customer
Thanks to this Gree wall-mounted heat pump, the owner of this Rosemont–La Petite-Patrie apartment now benefits from:
-
Four-season comfort : gentle and even warmth in winter, controlled coolness in summer;
-
Significant energy savings compared to electric heating alone;
-
The silence of modern, well-sized and well-installed equipment;
-
A discreet installation, integrated under the balcony, which does not interfere with the aesthetics of the courtyard or the flow of traffic.
For the customer, it also means peace of mind knowing that the system is installed by a certified team, with local after-sales service and technicians who are thoroughly familiar with Gree products.
