A four-season comfort solution in a Montreal duplex
In the Villeray–Saint-Michel–Parc-Extension sector, red brick duplexes and triplexes make up a large portion of the housing stock. For these buildings, often equipped with semi-buried basements and compact facades, the integration of an energy-efficient heating and cooling system must be carefully considered. It is precisely in this context that AirGreen installed a Sharp Eco Inverter wall-mounted heat pump , perfectly suited to the needs of a family looking to reduce its energy consumption while increasing its comfort.
Sharp Eco Inverter Technology
The Sharp Eco Inverter is a wall-mounted heat pump designed to offer:
-
High efficiency in heating and air conditioning thanks to inverter technology.
-
Stable performance even during the cold winters of Greater Montreal.
-
A reduction in electricity consumption, compared to old resistive heating systems or traditional air conditioners.
-
An Energy Star certification, making the equipment eligible for several provincial and federal grant programs.
Particularities of the site
The outdoor unit was installed on the brick wall using sturdy galvanized wall brackets , raised to avoid contact with the ground and prevent the accumulation of snow or moisture. This type of mounting not only guarantees mechanical stability , but also ease of future maintenance.
The electrical wiring and refrigerant connections were carefully fixed along the facade with discreet capping , integrating harmoniously with the exterior cladding. The condensation drain, meanwhile, was configured as a gravity flow, thus limiting the risk of backflow.
Implementation steps
-
Site preparation : identification of existing conduits, verification of the facade and anchor points.
-
Controlled drilling for the passage of pipes, with adequate insulation to ensure the wall is watertight.
-
Installation of the Sharp outdoor unit on anti-corrosion metal brackets.
-
Electrical connection in compliance with RBQ standards, incorporating a dedicated safety circuit breaker.
-
Complete tests : airflow verification, remote control calibration and heating and cooling mode tests.
Challenges met
-
Height management : the installation had to take into account the natural slope of the land, partly inclined, to ensure optimal clearance around the compressor.
-
Restricted access : the rear facade being narrow, our team optimized the positioning in order to maintain circulation around the house and access to the basement windows.
Results and benefits for the client
The family now benefits from a reliable, quiet, and energy-efficient HVAC solution that maintains a comfortable temperature year-round. The Sharp Eco Inverter system reduces heating costs in winter while providing efficient air conditioning in summer. The seamless integration of the outdoor unit into the facade also helps preserve the building's aesthetics.
AirGreen Tips for Similar Installations
-
Always allow sufficient installation height for the condenser to anticipate snow accumulations.
-
Opt for capping that matches the exterior cladding to maintain a discreet aesthetic.
-
Carefully evaluate BTU capacity based on the size and insulation of the home.
-
Schedule annual HVAC maintenance to ensure longevity and maximum efficiency of the system.
