When this Brossard homeowner contacted us, his goal was clear: to make the back room of his house—a sunroom overlooking the yard—comfortable year-round, while maintaining a clean, discreet, and durable outdoor installation. We recommended and installed a Gree wall-mounted heat pump , a reliable and efficient system perfectly suited to the Greater Montreal climate.
A typical South Shore bungalow, with very real constraints.
The house is a bungalow with a basement, vinyl siding and an exposed concrete foundation, typical of residential areas in Brossard.
The outdoor unit was supposed to:
-
to integrate close to the side wall, already occupied by the electric meter and the rainwater downpipe;
-
remain easily accessible for maintenance;
-
to be protected from snow accumulation and splashes related to rainwater runoff.
The space under the solarium offered an ideal area: well ventilated, sheltered from direct precipitation and sufficiently open to ensure good air circulation around the heat pump.
Choosing a Gree wall-mounted heat pump
For this project, we installed a Gree wall-mounted heat pump of approximately 12,000 BTU , a capacity typically used to air condition and heat a large living room, a solarium, or an open floor.
This type of system offers several advantages for a house in Brossard:
-
Four-season operation : the Gree heat pump is designed to provide heating even in cold weather, making it a relevant solution for Quebec winters.
-
Inverter technology : the compressor modulates its power according to actual needs, which reduces electricity consumption, improves comfort and increases the lifespan of components.
-
Quiet operation : the outdoor unit is very quiet, which is important in a residential area where the houses are relatively close together.
Inside, the Gree wall head diffuses air evenly, without unpleasant drafts, for very stable comfort in summer as in winter.
A neat and elevated outdoor installation
The photo shows the outdoor unit installed on a galvanized steel support , itself placed on leveled concrete slabs. This configuration is not merely an aesthetic detail: it plays a key role in the equipment's durability.
Protection against snow and frost
-
The device is raised above the ground to stay above the snow crust and ice accumulations.
-
The solarium creates a slight natural canopy, limiting direct snow and ice falling on the unit.
-
We checked the rainwater management around the existing downspout: the black extension visible on the ground directs water away from the foundation and the heat pump, reducing the risk of puddles and freezing around the support.
Clearances and air circulation
The heat pump is positioned a safe distance from the wall and any obstacles, which ensures:
-
a free flow of air at the suction and discharge points ;
-
maximum performance in both heating and cooling modes;
-
a reduction in noise and vibration, since the air circulates easily without recirculating around the unit.
Aesthetic finishes and electrical compliance
In every AirGreen project, we attach great importance to the finishing touches.
Route of the conduits
The refrigerant lines and condensate drain are housed in a vertical beige cover that runs discreetly along the wall. This cover:
-
protects the pipes from UV rays and impacts;
-
facilitates possible maintenance or replacement;
-
integrates seamlessly with the existing vinyl flooring.
The result: a tidy wall, without visible cables or pipes "hanging" randomly.
Food and safety
Right next to the outdoor unit, there is an accessible electrical disconnect box , in accordance with electrical code requirements.
This configuration allows:
-
to quickly cut off the power supply during maintenance;
-
to ensure the safety of our technicians' interventions, as well as those of any electrician mandated by the client.
The power supply is properly drawn from the house's electrical panel, respecting the wiring gauges, the dedicated circuit breaker and the necessary protections for a device of this power.
Four-season comfort in the solarium
It is in the back room, adjoining the area visible in the photo, that the magic happens on a daily basis.
Thanks to the Gree wall-mounted head :
-
In summer , the temperature remains pleasant even during periods of intense heat, despite the strong exposure of the glass-enclosed room to sunlight;
-
In mid-season , the device allows you to postpone the use of central heating or baseboard heaters, by quickly heating only the occupied area;
-
In winter , the heat pump provides efficient supplemental heating, which is very useful when the solarium is used as an office, games room, or relaxation area.
The very quiet indoor fan allows you to enjoy the room without disturbing noise, whether for working, reading or receiving guests.
Real energy savings
Compared to a traditional air conditioner combined with direct electric heating, a Gree wall-mounted heat pump offers:
-
to reduce annual electricity consumption , thanks to a coefficient of performance (COP) greater than 1 even at low temperatures;
-
to smooth out the power demand on the network, which can help limit peaks in winter;
-
to increase the level of comfort while controlling costs.
On the South Shore, where many homes already rely on electric systems, adding a wall-mounted heat pump is one of the simplest ways to reduce Hydro-Québec bills without major renovations.
AirGreen: a trusted partner for your Gree projects in Brossard
This project perfectly illustrates our approach at AirGreen:
-
analysis of the building and the client's actual needs ;
-
selection of suitable equipment – here a Gree wall-mounted heat pump – which offers excellent value for money and performance;
-
rigorous installation : raised support, clearance management, conduit protection, electrical compliance;
-
Attention to aesthetic detail , so that the heat pump integrates naturally into the architecture of the house.
Whether you wish to air-condition a solarium, an open-plan ground floor or upstairs bedrooms, we can offer you a Gree solution or another brand from our extensive range, always according to your budget and your reality.
