A discreet and efficient HVAC solution for a typical Montreal duplex
At AirGreen , we recently installed a Zephyr wall-mounted heat pump in a brick duplex in the Rosemont–La Petite-Patrie neighborhood , an area known for its multi-story homes, rear balconies, and unique urban character. This project perfectly illustrates our approach: combining energy efficiency, aesthetic discretion, and sustainable performance , all adapted to the architectural realities of Montreal.
An ideal configuration for two-story residences
The client wanted a heating and cooling solution capable of maintaining consistent comfort year-round without encroaching on interior space. The Zephyr wall-mounted heat pump was a natural choice: compact, quiet, and perfectly suited to the needs of urban housing.
Our team installed the outdoor unit on galvanized wall brackets , allowing optimal air circulation while freeing up the floor. Condensate drainage is by gravity , eliminating the need for an additional pump, while the white casing of the refrigerant lines ensures a neat finish and lasting protection against the elements.
Technical details and benefits of the Zephyr system
Zephyr wall systems are distinguished by their stable performance even in extreme temperatures . Depending on the configuration, they can provide efficient heating down to -25°C , a major asset for Montreal winters.
Here are some key features of the installed model:
-
Type: single-zone wall-mounted heat pump
-
Brand: Zephyr
-
Power: approximately 12,000 to 18,000 BTU (depending on the size of the home)
-
Installation: wall mounted on exterior support, direct electrical wiring, complete aesthetic cover
-
Sound level: very low, ensuring optimal acoustic comfort
-
Simplified maintenance thanks to quick access to filters and refrigerant connections
A typical Montreal installation challenge
Access to the backyard was restricted, requiring careful logistics for positioning and securing the compressor. Our technicians planned each step to minimize impacts on the existing brick , while ensuring solid anchoring and safe condensate drainage .
All wiring and refrigerant lines have been carefully routed through a discreet passage to the indoor unit , ensuring a smooth and secure installation.
Performance and comfort: a successful balance
Since installation, the customer has benefited from constant thermal comfort , a significant reduction in electricity consumption , and silent operation that fits perfectly into neighborhood life.
Zephyr modulation technology automatically adjusts power according to ambient temperature, ensuring maximum energy efficiency and smooth operation year-round .
An installation eligible for subsidies
As several Zephyr models meet ENERGY STAR® standards, they may be eligible for certain provincial and municipal grant programs (for example, the Rénoclimat or Chauffez vert program).
At AirGreen, we support our customers in these steps, providing them with all the information necessary to maximize their savings .
