Installation of a Gree wall-mounted heat pump on a flat roof in Brossard

In this modern residence in Brossard, on Montreal's South Shore, the owners wanted a high-performance, discreet heating and cooling system perfectly suited to their flat-roofed home. They chose to entrust us with the installation of a Gree Inverter wall-mounted heat pump to enjoy year-round comfort while reducing their energy bills.

Project context: a contemporary house, a need for year-round comfort

The house is clad in horizontal wood siding, with a flat roof covered in a white membrane. As is often the case in this type of construction, ground space around the house is limited, and the clients wanted to avoid having a condenser placed directly on their terrace or near the entrance.

Our objectives:

• find a discreet and secure location for the outdoor unit;

• protect the roof membrane and prevent any transmission of vibrations into the structure;

• to guarantee optimal heating operation during the Quebec winter, even during the coldest weather.

Choosing a Gree Inverter wall-mounted heat pump

The chosen solution: a Gree Inverter wall-mounted heat pump, single zone, 12,000 BTU , ideal for air conditioning and heating the main living areas of the house.

Why this choice is wise for a residence like this:

• Inverter technology : the compressor continuously modulates its power, which reduces temperature variations, decreases electricity consumption and extends the life of the device.

• Quiet comfort : Gree units are known for their low noise level, both inside and outside, a crucial point in a dense residential area like Brossard.

• Heating performance : the heat pump provides stable heating over a wide temperature range, which greatly reduces reliance on auxiliary electric systems.

A flat roof installation designed for Quebec winters

The photo clearly shows the Gree outdoor unit mounted on a raised aluminum support , itself anchored to treated wooden beams resting on protective panels. This assembly is not a minor detail: it is central to the quality of the installation.

Roof membrane protection

The roof is covered with a granular membrane typical of residential flat roofs. We have:

• protective panels were installed under the beams to distribute the load and preserve the integrity of the membrane;

• used treated wood to resist moisture and temperature variations;

• fixed the aluminium support in such a way as to stabilize the unit without unnecessarily piercing the roof.

Result: the membrane is protected, the weight of the unit is well distributed, and access to the roof for maintenance remains simple and safe.

Optimized height for snow and drainage

The raised support allows the condenser to be kept:

• above the snow accumulated in winter, which avoids obstruction of air exchanges and the risk of blockage during defrosting cycles;

• at a sufficient height so that the water from defrosting can drain freely, without creating ice patches against the appliance.

This height is calculated for the climate of the greater Montreal area, where episodes of heavy snow and thaws are frequent.

Air circulation and distance from the wall

We also complied with the clearances recommended by the manufacturer Gree:

• sufficient distance between the back of the unit and the wooden facing to ensure good air circulation ;

• centered positioning on the support to limit vibrations;

• Orient the device so that the airflow is not directed towards passage or relaxation areas on the roof.

All these elements contribute to quiet operation, both for the occupants and for the neighborhood.

High-quality finish: aesthetics, safety and accessibility

Even though the unit is on the roof and therefore not very visible from the street, we pay particular attention to aesthetics and finish:

• Electrical wiring and refrigeration connections are stored and protected in appropriate conduits;

• Visible fixings are minimized, and components are aligned for a clean and professional finish;

• The location allows easy access for annual maintenance or any service intervention.

We always check the connections for leaks, the proper evacuation of the refrigerant circuit, and the charging parameters before commissioning. The system is then tested in both cooling and heating modes to ensure everything is working perfectly.

Comfort and savings for the occupants

Thanks to this Gree Inverter wall-mounted heat pump, the occupants of this Brossard home now enjoy:

• of a gentle and stable coolness in summer , without unpleasant drafts;

• efficient and economical heating in winter , which reduces the need for supplementary electricity;

• of a silent system, which does not disturb the tranquility of the place, even in the evening;

• better control of their energy costs, thanks to Inverter modulation and the high seasonal efficiency of the device.

By combining good home insulation, intelligent thermostat management and regular maintenance, the heat pump becomes a real ally for the wallet… and for everyday comfort.
