A high-performance and sustainable solution for a commercial building
At AirGreen , we recently completed an HVAC installation in the Saint-Laurent area of Montreal. The project involved installing a Daikin central heat pump on the flat roof of a commercial building, a solution perfectly suited to the heating and cooling needs of professional spaces.
This type of installation presents technical and logistical specificities that require specialized expertise. The goal was to ensure optimal operation throughout the year, including during the harsh winters of Greater Montreal.
Why choose a Daikin central heat pump for a commercial building?
The Daikin brand is recognized worldwide for its reliable, efficient equipment designed for the North American climate . Installing a Daikin unit on a flat roof offers several advantages:
-
High energy performance , reducing annual operating costs.
-
Heating/air conditioning versatility , capable of maintaining indoor comfort in summer and winter.
-
Adaptability to large spaces , ideal for offices, shops and multi-tenant buildings.
-
Durability : Designed to withstand Montreal's extreme weather conditions, including snow, ice and heavy rain.
Key steps of installation
Our specialized technicians have proceeded methodically to guarantee the performance and safety of the installation:
-
Roof preparation : a clear and stable space was chosen to accommodate the outdoor units.
-
Raised supports : the heat pumps were fixed on treated wooden rails and metal bases to ensure good stability and avoid any direct contact with the roof gravel.
-
Refrigeration and electrical connections : the connections have been carefully insulated and protected to ensure maximum longevity. The electrical cables have been routed to a dedicated junction box (labeled 408 ), ensuring safety and compliance.
-
Weather protection : Insulating hoods and sheaths were installed to protect the piping from cold and humidity.
-
Commissioning and testing : after connection, comprehensive testing ensured the heat pump was operating correctly in heating and air conditioning modes.
Technical challenges and solutions
A flat roof installation is never trivial. In this project, two major constraints arose:
-
Condensate drainage management : On a flat roof, it is essential to prevent any water accumulation. We have provided efficient drainage to ensure that condensate drains properly, even in freezing weather.
-
Distance between the units and the electrical panel : the cable run required precise planning in order to reduce electrical losses and ensure an installation that complies with current standards.
Thanks to our expertise, these challenges were successfully met, guaranteeing a high-performance and safe installation.
A profitable and energy-efficient investment
Opting for a Daikin central heat pump not only reduces your energy bill, but also allows you to take advantage of grants available in Quebec for energy-efficient systems. These financial aids can cover part of the costs, making this type of project even more advantageous for property managers and commercial owners.
