An optimized HVAC installation project for a residential building
At AirGreen , we recently completed a Gree wall-mounted heat pump installation on the flat roof of a residential building in Verdun , a rapidly evolving neighborhood of Montreal. The project was distinguished by a technical challenge: integrating the outdoor units onto a white, wind-exposed roof, while ensuring lasting stability and optimal performance in all seasons.
A strategic choice: the Gree heat pump for lasting comfort
The owners opted for a Gree wall-mounted heat pump , known for its reliability and performance even during the harsh winters of Greater Montreal. The advantages are clear:
-
High energy efficiency , reducing power consumption.
-
Heating performance down to -25°C, ensuring constant comfort.
-
Eligibility for grants available in Quebec for Energy Star certified equipment.
-
Increased durability , essential for a system installed on the roof.
Technical details of flat roof installation
The installation required meticulous planning, as wall-mounted heat pump outdoor units must be properly secured and insulated on a roof to withstand climatic variations.
-
Raised support made of treated wood and stabilizing blocks , to protect the roof and avoid any direct contact with the membrane.
-
Wiring and piping protected by white capping , in harmony with the roof and ensuring optimal insulation of the refrigerant pipes.
-
Gravity drainage of condensates, simplified by the slight slope of the roof.
-
Two outdoor units installed , each supplying a separate indoor area, a perfect choice for a multi-unit building.
Constraints encountered and solutions provided
-
Roof working height : our technicians used secure access and anchoring systems to comply with safety standards.
-
Wind exposure : Raised supports have been reinforced to prevent excessive vibration.
-
Length of refrigerant lines : The distance between the outdoor units on the roof and the indoor heads required careful insulation to maintain energy efficiency.
