An elegant and efficient installation by AirGreen in the heart of Montreal
At AirGreen , we recently completed a superb installation of a Sharp ZU1 Eco Inverter wall-mounted heat pump in a typical brick duplex in the Rosemont–La Petite-Patrie neighborhood of Montreal. This project perfectly illustrates our expertise: combining energy performance, aesthetics, and sustainability in a dense urban environment, while respecting local architectural specificities.
A Sharp ZU1 wall-mounted heat pump: power and reliability
The Sharp ZU1 Eco Inverter is a benchmark model in the high-efficiency wall-mounted heat pump category. Operating with R-32 refrigerant, it offers a performance range down to −25 °C , making it ideal for Montreal's climate. Thanks to Plasmacluster Ion technology , this unit purifies the ambient air by eliminating bacteria, mold and odors, ensuring healthy indoor comfort all year round.
Main features:
-
Capacity: 12,000 BTU
-
Technology: Eco Inverter with intelligent modulation
-
Seasonal Energy Efficiency Ratio (SEER): up to 23
-
Efficient heating at −25°C
-
R-32 refrigerant (environmentally friendly, low global warming potential)
-
Sharp's exclusive Plasmacluster Ion function
Details of the AirGreen installation in Rosemont
This installation was carried out on a red brick facade , typical of Montreal plexes. The Sharp outdoor condenser was securely fixed to galvanized wall brackets , ensuring perfect stability while avoiding any contact with the ground. This arrangement promotes better air circulation and reduces the accumulation of snow and humidity during the winter.
The refrigerant pipes and electrical cables were carefully routed in beige capping that matches the cladding, for a discreet and harmonious appearance. Condensate drainage is carried out by gravity, ensuring smooth flow even in cold weather.
Finally, the power supply was integrated nearby, complying with RBQ and CSA standards, while minimizing the visual impact.
Project context and constraints on the site
As the building is old, the main constraint was the routing of the conduits through solid brick walls. Our technicians carried out a precise and sealed drilling to preserve the thermal insulation and watertightness of the wall.
Particular attention has also been paid to reducing vibrations : we have added anti-vibration silent blocks under the supports to ensure silent operation, both indoors and outdoors.
Everything was completed in one day's work , including vacuuming, pressure checking, system calibration and full demonstration to the customer.
A sustainable choice for comfort and savings
The Sharp ZU1 is an Energy Star certified heat pump, making it eligible for several grant programs offered in Quebec, including those of Hydro-Québec and the Chauffez vert program. Thanks to its efficiency, homeowners benefit from a significant reduction in their electricity consumption , while increasing the value and comfort of their home.
In addition, the ZU1 series is designed to last: its inverter compressor protects against overloads and extends the life of the unit, even in extreme weather conditions.
