A successful energy upgrade in a Montreal duplex
In the Ahuntsic-Cartierville neighborhood of Montreal , a client wanted to modernize their thermal comfort while reducing their energy bills. We installed a Gree wall-mounted heat pump , a wise choice for its recognized performance, energy efficiency, and adaptability to the needs of typical residential homes in the area.
The context of the project
The client already had a small outdoor space limited by a metal staircase and a secondary entrance opening onto the courtyard. The main constraint was therefore managing the space to install the condenser without hindering traffic flow or daily maintenance. We chose to install the outdoor unit on a raised galvanized steel support , guaranteeing:
-
optimal air circulation,
-
protection against the accumulation of snow and water,
-
ease of access for future maintenance.
Technical characteristics of the Gree heat pump
The Gree range of wall-mounted heat pumps is appreciated for its reliability in the Quebec climate. Its advantages include:
-
Heating capacity down to -25°C , ideal for Montreal winters,
-
High energy efficiency (SEER and HSPF meet Energy Star standards) ,
-
Quiet system, both inside and outside,
-
Compatibility with provincial and federal grant programs (LogisVert, Maison plus verte).
Installation process
Preparation and connections
We started by assessing the optimal route for the refrigeration lines . The route was carried out along the existing brick wall, with a discreet exit protected by white insulating capping to ensure a clean and durable finish.
The electrical connection was facilitated by the immediate proximity of the distribution panel and the electricity meter , reducing installation costs and times.
Condensate management
As the client has a terrace with a natural slope, the drainage was designed by gravity , thus avoiding the use of a condensate pump. This approach promotes the reliability of the system and limits maintenance requirements.
Aesthetics and safety
Particular care was taken to integrate the heat pump into the existing environment. The space remains clear to allow for watering the garden and using the garden hose, while preserving circulation around the stairs.
Benefits for the customer
From the moment it was turned on, the family enjoyed increased comfort in both heating and cooling. In winter, the Gree heat pump takes over from an existing electric heating system, generating substantial savings on electricity costs. In summer, it provides consistent and quiet air conditioning, a valuable asset during heat waves.
AirGreen's advice for this type of installation
-
Always provide raised support for outdoor units in Montreal to anticipate snow.
-
Check the proximity of the electrical panel to limit cable length and optimize costs.
-
Ensure sufficient clearance around the condenser for annual maintenance.
-
Favor gravity evacuation of condensate when the configuration allows it.
