Careful installation on a flat roof to optimize energy efficiency
At AirGreen , we recently completed a Sharp Eco Inverter wall-mounted heat pump installation in a residential building in Plateau-Mont-Royal, Montreal . This project perfectly illustrates our expertise in HVAC installation on flat roofs, which are common in Montreal's central neighborhoods.
Why choose the Sharp Eco Inverter?
The Sharp Eco Inverter is renowned for its energy efficiency and ability to operate even in harsh winter conditions. It combines:
-
Inverter technology : intelligent power modulation to maximize energy savings.
-
Plasmacluster Ion : active purification of indoor air, a major asset for urban environments where air quality is often compromised.
-
Cold climate performance : reliable heating efficiency down to −25°C.
-
Eligibility for subsidies : government programs such as Hydro-Québec and LogisVert, subject to performance conditions.
This machine is an ideal choice for Montreal families and homeowners looking for a balance between comfort, savings and durability.
Challenges of Flat Roof Installation
Installing a compressor on a typical flat roof in the Plateau requires special expertise. The main constraints encountered in this project:
-
Weight and stability management : Requirement to use weighted rail supports to protect the roof membrane.
-
Condensate drainage : gravity installation with optimized slope to avoid any risk of water stagnation.
-
Weather protection : choose an open location to ensure optimal air circulation and avoid snow accumulation in winter.
Our technicians used an aluminum structure with treated wooden rails to evenly distribute the load and minimize any pressure on the roof.
Installation process
-
Roof preparation : inspection of the membrane and choice of a stable and accessible area.
-
Installation of the support : fixing on weighted rails for maximum stability without perforation of the roof.
-
Refrigerant pipe routing : secure routing through a technical outlet, with discreet metal capping to protect and insulate the connections.
-
Electrical connection : direct connection to the housing panel, in accordance with the Quebec Electrical Code.
-
Performance tests : verification of refrigerant pressures, heating and air conditioning cycle, as well as sound level.
Results for the client
Upon startup, the owner noticed:
-
quiet operation , even at full power;
-
a significant improvement in indoor air quality thanks to Plasmacluster technology;
-
a solution perfectly adapted to the specificities of Montreal buildings with flat roofs .
This installation not only guarantees thermal comfort all year round, but also a significant reduction in energy bills.
