An energy upgrade on the facade of a typical Montreal duplex
In Rosemont–La Petite-Patrie, a neighborhood with undeniably Montreal charm, featuring brick facades and abundant greenery, our AirGreen team recently installed two Sharp ZU1 wall-mounted heat pumps on the rear facade of a duplex. This project perfectly illustrates our expertise in HVAC installation in urban residential buildings, where every square meter counts and energy performance should never compromise the building's aesthetics.
A strategic choice: the Sharp ZU1 series
The Sharp ZU1 are new generation R-32 wall-mounted heat pumps , designed for Quebec's harsh winters. Offering stable performance down to -25°C , they are an ideal solution for Montreal homes looking to improve their comfort while reducing their energy bills.
Each compact and quiet unit is equipped with a high-efficiency inverter compressor, ensuring rapid heating and precise cooling .
A meticulously planned construction site
The installation took place on the rear brick facade , at the level of the raised ground floor of the duplex.
Our technicians have:
-
Securely fixed the condensers on galvanized wall brackets , optimizing floor space in a narrow yard.
-
Routed the refrigerant and electrical lines in an orderly manner, with beige capping matching the masonry .
-
Checked the gravity drainage of condensates, ensuring natural flow to avoid any water stagnation.
-
Tested each unit with a complete heating and cooling cycle , confirming perfect sealing and thermal efficiency.
A perfect adaptation to the urban context
Installing two units side by side on a common brick wall requires great precision. The available space was limited by vegetation and the metal staircase leading to the roof.
So we adjusted the mounting heights to ensure optimal airflow between the condensers, while meeting Sharp's clearance requirements and AirGreen's HVAC standards.
This independent dual unit configuration allows each home to adjust its comfort according to its needs, while maintaining balanced electricity consumption.
Results: efficiency, comfort and peace of mind
Occupants now benefit from four-season comfort , with reduced noise levels , controlled energy consumption , and eligibility for Quebec subsidies for high-efficiency Energy Star appliances.
The aesthetics of the facade are preserved, and the overall performance of the system reaches the best market standards.
