A high-performance HVAC solution on a flat roof in the heart of Montreal
At AirGreen , we recently completed a Sharp Eco Inverter wall-mounted heat pump installation in the Rosemont–La Petite-Patrie area. This project perfectly illustrates our expertise in HVAC installation on flat roofs , a common configuration in Montreal apartment buildings and plexes.
Project background
Our client, a duplex owner, wanted an efficient, discreet, and sustainable heating and cooling solution to improve year-round comfort. The main objective was to reduce dependence on traditional electrical systems while maximizing energy savings, particularly during Montreal's harsh winters.
Details of installed equipment
-
Brand: Sharp
-
Model: Eco Inverter
-
Type: Wall-mounted heat pump (mini-split)
-
Technology: Inverter with Ion Plasmacluster (integrated air purification)
-
Capacity: suitable for an average-sized home
-
Support: metal structure fixed on insulation and treated wooden crosspieces, placed on a flat roof
This combination guarantees a stable and secure installation, capable of withstanding local climatic variations (rain, snow, summer heat).
Key steps of installation
-
Flat roof assessment : inspection of waterproofing and choice of a location allowing good air circulation.
-
Installation of the support : use of high-density insulating blocks and treated wooden sleepers to prevent any infiltration and distribute the load.
-
Refrigerant connections : passage of pipes from the outdoor unit to the interior, respecting the necessary slopes for gravity evacuation of condensates.
-
Electrical check : connection to the main electrical panel and protection via dedicated circuit breaker.
-
Testing and calibration : gradual start-up, pressure verification, inverter adjustment and energy efficiency validation.
Constraints and solutions provided
-
Working height on flat roof : use of a raised support to protect the heat pump from snow and water accumulations.
-
Access to the ducts : discreet integration of white capping to protect the refrigerant connections and ensure an aesthetic finish on the interior side.
Results obtained
The customer now benefits from four-season comfort :
-
Effective air conditioning during summer heat waves.
-
Stable heating even at temperatures around -25°C.
-
Purified air thanks to Sharp Plasmacluster technology.
-
Greater energy savings compared to its old heating system.
Grants and financial benefits
Sharp Eco Inverter heat pumps are eligible for grant programs available in Quebec, such as LogisVert and Maison plus verte . In this project, we assisted the client with the administrative procedures to reduce the initial cost of the investment.
