An HVAC installation perfectly suited to Montreal’s flat roofs
At AirGreen , we often encounter urban contexts where the installation of a wall-mounted heat pump requires special adaptation to the flat roofs of residential and commercial buildings in Montreal. In this project in Saint-Laurent , we installed a Sharp Eco Inverter outdoor unit, known for its energy efficiency and reliability in the Quebec climate.
Choosing the Sharp Eco Inverter heat pump
The Sharp Eco Inverter is a popular model among our customers who are looking for a balance between performance, reliability, and controlled operating costs. Designed to withstand our harsh winters, it offers:
-
Stable heating capacity down to very low temperatures.
-
Quiet operation , both indoors and outdoors.
-
High energy efficiency , reducing electricity costs.
-
Compatibility with provincial and federal grant programs , including LogisVert and Greener Homes.
With available power ranging from 9,000 to 24,000 BTU , this range covers small condos as well as single-family homes or medium-sized businesses.
Technical details of flat roof installation
For this project, several constraints were identified and resolved thanks to the expertise of our team:
-
Flat roof support : The outdoor unit was installed on raised supports with treated wooden crosspieces , resting on a stabilized base with insulating foam. This protects the roof gravel while ensuring even weight distribution.
-
Refrigerant pipe routing : the wiring and insulated piping were routed through a technical duct, carefully sealed to prevent any water infiltration.
-
Condensate management : the configuration allowed gravity drainage , avoiding the addition of a lifting pump.
-
Working at Height : Although the unit was on a roof, the drop remained low (less than 8 feet), eliminating the need for a working at height surcharge.
This type of installation perfectly illustrates the versatility of Sharp HVAC solutions in an urban environment.
The benefits of an installation optimized by AirGreen
Every installation we carry out is designed to maximize the lifespan of the equipment and minimize maintenance costs . In this specific case:
-
The raised support protects against snow and ice accumulation.
-
Insulating pipes limits heat loss and improves efficiency.
-
The wiring is organized to facilitate any future maintenance.
We also emphasize the importance of regular maintenance : cleaning filters, inspecting connections, and checking the condensate drain. These simple steps can prevent 80% of common breakdowns.
