A heat pump installation adapted to Montreal’s flat roofs
At AirGreen , we recently completed a Fujitsu wall-mounted heat pump installation on a flat roof in the Hochelaga-Maisonneuve area. This neighborhood, known for its residential and commercial buildings, often requires HVAC solutions tailored to flat roofs exposed to Montreal's extreme weather conditions.
Installing a heat pump on a snow-covered roof presents a unique challenge: a sturdy raised support, secure routing of refrigerant lines, and adequate protection against snow and ice accumulation are required.
Why choose a Fujitsu heat pump in Hochelaga-Maisonneuve?
The Fujitsu wall-mounted heat pump is renowned for its reliability, high energy efficiency, and ability to operate efficiently even in Quebec's bitter cold. This unit, designed to provide stable heating down to -25°C, is ideal for buildings in Greater Montreal where harsh winters put HVAC equipment to the test.
In addition, Fujitsu offers several Energy Star certified models, which makes this installation eligible for grant programs available in Quebec, particularly for residents of Montreal, Laval, Longueuil, as well as the North and South Shores.
The technical challenges of a flat roof installation
Galvanized steel raised support
In this installation, the outdoor unit was placed on a raised galvanized steel support , ensuring stability and preventing any obstruction due to accumulated snow. This choice also ensures a longer lifespan for the unit, by reducing the risk of corrosion.
Winter conditions management
As the situation shows, the roof was already covered in snow at the time of the work. Our technicians took care of:
-
clear the installation area to ensure adequate ventilation,
-
check condensate drains to prevent ice buildup,
-
install reinforced insulation of refrigerant pipes exposed to the cold.
Wiring and electrical box
The electrical connection was made with a protective box suitable for outdoor conditions . The cables were carefully sheathed to withstand temperature variations, ensuring safety and reliability.
Benefits for the customer
With this installation, the customer now benefits from:
-
Four-season comfort : efficient heating in winter and effective air conditioning in summer.
-
Energy savings thanks to Fujitsu high energy efficiency.
-
A sustainable system protected against the harshness of Montreal winters.
-
Access to grants available for improving the energy efficiency of buildings.
