In Rosemont–La Petite-Patrie, condominiums and residential buildings are being modernized to offer greater year-round comfort while reducing their energy bills. This project aims to achieve just that: installing aSharp wall-mounted heat pump on the roof of a building, with an outdoor condenser mounted on a raised structure perfectly suited to Montreal's climate.
Project context: air conditioning and heating an urban building
The building where we intervened is typical of Rosemont–La Petite-Patrie: brick construction, flat roof covered with gravel, several stacked apartments and a close proximity to neighboring buildings.
The occupants' priorities were clear:
-
To ensure stable comfort in the targeted housing, both in summer and winter ;
-
Minimize noise and obstructions on the ground and in the yard;
-
Optimize energy efficiency with a high-performance heat pump;
-
Respect architectural and co-ownership constraints (roof, visibility, access, maintenance).
We recommended a Sharp Eco Inverter multi-zone wall-mounted heat pump , a reliable, compact and efficient system, perfectly suited to residential buildings in Greater Montreal.
Choosing the Sharp Eco Inverter heat pump
Sharp is a brand renowned for its robust and efficient residential air conditioning systems. In this project, we installed a Sharp Eco Inverter wall-mounted heat pump , from a range comparable to the Sharp ZU1 series, designed for heating and cooling in northern climates.
Advantages of the Sharp heat pump for this project
-
Inverter technology : power is precisely adjusted to actual needs, reducing frequent starts, lowering consumption and improving compressor life.
-
High-performance heating mode in winter : a heat pump designed to operate reliably at low temperatures, ideal for Montreal's harsh winters.
-
Quiet comfort : the Sharp condenser is designed to limit noise, which is crucial on a roof shared between several units.
-
Air quality : Sharp's clean air treatment technology contributes to healthier indoor air, which is particularly appreciated in urban environments.
Installation on a gravel roof: precision and stability above all
One of the unique aspects of this project is its installation on a flat gravel roof . This type of configuration requires special attention to ensure the safety, watertightness, and longevity of the system.
Elevated structure and clearances
The photo clearly shows the Sharp condenser mounted on a raised steel chassis . This approach allows for:
-
Protect the unit from water and ice accumulation during snowmelt or heavy rains;
-
Ensure adequate clearance for air circulation around the unit;
-
Distribute the weight on the roof using supports placed on suitable bases, so as not to damage the membrane.
We always make sure to respect the clearances recommended by the manufacturer to optimize both performance and accessibility for maintenance.
Management of refrigeration and electrical connections
The refrigeration lines are visible on the floor, carefully insulated and grouped in black sleeves in order to:
-
Limit energy losses;
-
Protect the pipes from UV rays, cold and impacts;
-
To provide a clean and professional finish.
Electrical connections are made according to current standards, with dedicated circuit breakers and junction boxes accessible for future maintenance.
Coexistence with other systems
There are other condensers on the roof. We planned the installation of the Sharp system so that:
-
Maintain sufficient distances between units to avoid hot air recirculation;
-
Facilitate maintenance interventions without disrupting other equipment;
-
Maintain safe access routes for technicians.
Comfort for occupants in both summer and winter
Inside, the Sharp heat pump powers discreet wall-mounted units installed in the living areas and bedrooms. The result for the occupants:
-
In summer : efficient, fast and quiet air conditioning, even during heat waves.
-
Mid-season : fine temperature control, ideal in spring and autumn, without having to start a central heating system.
-
In winter : a stable and economical heat supply, which reduces dependence on more energy-intensive systems.
Thanks to Inverter technology, the indoor temperature remains stable, without large comfort variations or unpleasant drafts.
A meticulously designed installation by AirGreen
The photo also shows a technician finalizing checks on the roof. Every AirGreen project follows a rigorous methodology :
-
Analysis of the building and site : access to the roof, structure, orientation, presence of other equipment, routing of pipes.
-
Sizing and recommendation of the Sharp system based on the number of zones to be served and the actual heating/cooling needs.
-
Mechanical and electrical installation with secure fixing of the structure, installation of refrigeration connections, condensate drainage and connection to the electrical panel.
-
Complete commissioning : vacuuming, leak tests, pressure checks, remote control calibration, explanation of operation to occupants.
-
Follow-up and after-sales service : we remain available for seasonal maintenance and adjustment optimizations.
