An elegant and efficient solution for optimal comfort in all seasons
In a modern condominium in the Ville Saint-Laurent sector, our AirGreen team recently installed a Sharp ZU1 wall-mounted heat pump . Known for its exceptional energy efficiency and quiet operation, this unit represents the perfect balance between performance , sleek design and cutting-edge technology .
Project context: a compact space to be efficiently air-conditioned
The client, the owner of a condo located in a recently constructed building, wanted a heating and cooling solution that was both discreet and economical . The space to be served—a living room open to the kitchen—required a compact wall-mounted indoor unit capable of maintaining consistent comfort throughout the year, even during Montreal's harsh winters.
The Sharp ZU1 , operating with R-32 refrigerant , has established itself as the ideal choice thanks to its ability to offer stable performance down to −25°C , while meeting the requirements of energy subsidy programs available in Quebec.
Technical installation: precision and aesthetic integration
The wall unit was installed high up on a load-bearing wall , optimizing air diffusion throughout the room. The refrigerant connections were carefully routed through white covered wiring , perfectly aligned with the ceiling line for aesthetic integration .
Condensate is drained by gravity, eliminating the need for a pump and reducing maintenance points. The entire installation was completed to CSA standards and AirGreen best practices , ensuring watertightness, durability and maximum performance .

Why the Sharp ZU1 is a smart choice for Montreal
The Sharp ZU1 is distinguished by:
-
Its high energy efficiency (up to 26 SEER )
-
Its operating silence (barely 21 dB )
-
Its Inverter technology which adjusts power according to actual demand
-
Its compatibility with provincial grant programs
-
Its sleek design is perfectly suited to modern Montreal condo interiors.
Thanks to its R-32 refrigerant , this unit reduces environmental impact by 68% compared to older R-410A systems.
Result: comfort, economy and peace of mind
At the end of the project, the client immediately noticed remarkable thermal stability , even during the sudden temperature fluctuations typical of Greater Montreal. In cooling mode, the ZU1 cools quickly without direct airflow, while in heating mode, it maintains a gentle and uniform heat.
The minimal operating noise was also highlighted by the client, a major asset for an open-plan living space.
