In the quiet streets of Rosemont–La Petite-Patrie, in Montreal, we were commissioned to modernize the comfort of a duplex by installing a Gree wall-mounted heat pump .
The client's objective was clear: to enjoy a quiet, efficient system for both air conditioning and heating, without cluttering the courtyard and respecting the proximity of the neighbors.
Project context in Rosemont–La Petite-Patrie
The house is typical of the area:
-
red brick facade,
-
narrow asphalt driveway running alongside the building,
-
wire fence separating the property from the neighbor's,
-
small shed at the back of the yard.
The main challenge was therefore to install the outdoor unit in this confined space, while ensuring:
-
good air circulation around the condenser,
-
a minimal noise level for the occupants and the neighborhood,
-
sufficient clearance for maintenance and winter snow.
Choosing a Gree wall-mounted heat pump
We recommended a new generation Gree wall-mounted heat pump , perfectly suited to the needs of urban housing like that of Rosemont–La Petite-Patrie:
-
High-efficiency inverter technology, for optimized power consumption.
-
Four-season operation, with reliable heating capacity in cold weather , ideal for Montreal winters.
-
Compact size of the outdoor unit, which is well suited to the side walkways and alleys typical of Montreal plexes.
This type of Gree wall-mounted heat pump allows you to:
-
to effectively air-condition the living space in summer,
-
to provide stable heating in spring, autumn and winter,
-
reduce reliance on more energy-intensive systems such as electric baseboard heaters.
Details of the outdoor installation
The photo clearly shows the Gree outdoor unit installed along the brick wall on sturdy wall brackets . Several important technical choices were made:
1. Installation on wall brackets
Rather than placing the unit on a floor slab, we opted for:
-
galvanized steel wall brackets ,
-
equipped with pads and vibration dampers to limit the transmission of noise to the structure.
This configuration offers several advantages:
-
clearing the ground to prevent the accumulation of snow and ice;
-
protection against runoff water, debris and accidental impacts (rolling bins, lawnmower, etc.);
-
easy access for maintenance and service.
2. Compliance with clearances and ventilation
Even in this relatively narrow alley, we made sure to:
-
leave sufficient space at the rear and sides of the unit for air circulation;
-
position the heat pump so as to avoid recirculating hot air in heating mode;
-
maintain good clearance from the fence and surrounding elements.
These details are essential to guarantee the performance of the Gree heat pump and extend its lifespan.
3. Routing of refrigeration lines and drain
The refrigerant lines, electrical wiring, and condensation drain are:
-
grouped together in a discreet channel on the courtyard side ,
-
securely fixed to withstand freeze-thaw cycles,
-
designed to drain water away from the foundation and walkways.
The result: a clean, safe and aesthetically pleasing installation.
Comfort and performance in Quebec winters
In Rosemont–La Petite-Patrie, as elsewhere in Montreal, the systems have to deal with:
-
hot and humid summers ,
-
harsh winters, regularly below -20°C,
-
frequent freeze/thaw cycles.
The Gree wall-mounted heat pump installed here is designed to provide:
-
rapid and even cooling of rooms in summer;
-
stable heating at low outside temperatures, reducing reliance on electric baseboard heaters;
-
intelligent defrosting to limit performance losses during extreme cold.
Thanks to inverter modulation, the compressor continuously adjusts its speed, which allows:
-
to maintain a constant indoor temperature ,
-
to reduce peak electricity consumption ,
-
to increase the comfort and lifespan of the system.
Aesthetics, noise and neighborhood
In a dense neighbourhood like Rosemont–La Petite-Patrie, aesthetics and noise are two major criteria.
-
The Gree unit, with its understated and compact design, integrates well against the brick wall without dominating the outdoor space.
-
Vibration dampers installed under the condenser effectively limit structural noise.
-
Positioning it along the driveway, at a reasonable distance from the main courtyard, helps to preserve the peace and quiet of the occupants and neighbors .
In the evening and at night, the heat pump operates at a reduced speed, resulting in a very discreet noise level .
Maintenance and durability
To guarantee the longevity of this Gree wall-mounted heat pump, we have planned:
-
unobstructed access in front of the unit to allow for periodic cleaning of the external heat exchanger;
-
sufficient height to allow snow to be cleared in winter;
-
solid and corrosion-resistant fixings on the brick wall.
We recommend the following to the customer:
-
to have the system checked every 1 to 2 years,
-
to clean the filters of the indoor unit a few times per season,
-
to keep the space in front of the heat pump free of any obstruction (containers, objects, vegetation).
Minimal but regular maintenance ensures optimal performance and prevents operational problems.
