A high-performance and elegant HVAC solution for a Montreal brick building
In the Mercier–Hochelaga-Maisonneuve neighborhood, we recently installed Sharp ZU1 wall-mounted heat pumps . These new-generation R-32 units are distinguished by their energy efficiency, reliability in cold climates, and compact design that blends perfectly with Montreal's typical masonry buildings.
Choosing the Sharp ZU1 for optimal comfort
The Sharp ZU1 series is designed to meet residential and small multiplex needs. Thanks to its Eco Inverter technology and the Plasmacluster Ion purification system, it ensures both efficient heating in winter and healthy, filtered indoor air all year round. Each installed unit offers stable performance down to −25 °C , which is ideal for the Montreal climate.
-
Brand : Sharp
-
Model : ZU1 Series (R-32, high performance in cold climate)
-
System type : Wall-mounted heat pump (mini-split)
-
Installed capacity : two wall units, each sized for main rooms in the building
A neat installation on a brick facade
Our technicians mounted the two outdoor capacitors on sturdy wall brackets , suitable for loads and vibrations. To protect the integrity of the brick facade, each opening was carefully sealed and insulated.
The refrigerant and electrical pipes are routed using discreet and well-sealed capping , ensuring a clean and durable finish. The installation was carried out at an ergonomic height to facilitate future maintenance and optimize the units' heat dissipation.
Technical details and challenges of the project
-
Wall bracket : installation on galvanized brackets to clear the floor and avoid any direct contact with humidity.
-
Ducts : moderate length, run in a straight line along the wall, covered with aesthetic capping.
-
Electricity : dedicated outdoor connection box, installed in the immediate vicinity of the units for simplified access and compliant with RBQ standards.
-
Context : brick building typical of the area, requiring particular attention to anchors and waterproofing.
Thanks to careful planning, we were able to complete the installation without disturbing the occupants and minimizing the response time.
