Optimal comfort in a typical Montreal duplex thanks to the Sharp ZU1 series
At AirGreen , we recently completed the installation of a Sharp ZU1 wall-mounted heat pump in a cozy duplex in Montreal's Rosemont–La Petite-Patrie neighborhood. This area, known for its shared-wall buildings and compact interior spaces, requires efficient, quiet, and aesthetically pleasing HVAC solutions. This is exactly what the Sharp ZU1 range offers our customers.
A discreet and effective solution for a family space
The elegantly mounted indoor unit blends seamlessly into the room's decor—a family space where comfort and quiet sound were essential. With its R-32 inverter technology and efficient heating capacity down to −25°C , the Sharp ZU1 is an ideal choice for Montreal's climate.
The installation was carefully planned to minimize the visual impact of the wiring and ensure efficient gravity drainage . The refrigerant lines were routed through a load-bearing wall to the exterior, with discreet white cladding to match the interior finish.
Installation Steps
-
Location Assessment — Our team first inspected the space to determine the best indoor location, ensuring even air circulation throughout the room.
-
Wall-mounted head placement — Precise installation for optimal airflow, without disturbing furniture or decorative wall elements.
-
Duct Drilling and Routing — Direct and short passage to the outdoor condenser, reducing performance losses.
-
Connection and vacuuming — Rigorous verification of the system's leak-tightness and pressure.

Project context and constraints
As the property is located in a semi-detached building with no direct side access, our team opted for a compact vertical routing of the pipes. This avoided visible holes in the facade and preserved the building's exterior aesthetics , while complying with municipal installation standards.
The customer, sensitive to issues of air quality and energy efficiency, particularly appreciated the Sharp ZU1 's ability to provide stable heating even during the extreme cold of January, without the need for additional heating.
Result: comfort, silence and performance
Since commissioning, the family has noticed a significant improvement in thermal comfort and a reduction in heating costs . In summer, the air conditioning function ensures rapid cooling, while in winter, the heating mode maintains a constant temperature without sudden fluctuations.
At AirGreen , each installation is designed down to the smallest detail—from model selection to final commissioning —to offer our customers sustainable, efficient HVAC solutions adapted to the Montreal lifestyle.
In summary
This Sharp ZU1 wall-mounted heat pump installation in Rosemont–La Petite-Patrie perfectly illustrates our expertise: aesthetic integration , certified performance , and complete customer support , from product selection to initial start-up.
