In a typical Rosemont–La Petite-Patrie apartment, we recently installed aSharp wall-mounted heat pump to improve the comfort of a living space where every square meter counts. The client wanted a quiet, efficient solution for both heating and cooling, without sacrificing storage or interior aesthetics.
Context: urban housing where space is precious
The project is located in an apartment in a Montreal multiplex: central hallway, built-in wardrobe and several doors leading to bedrooms and living spaces.
The client's needs were clear:
-
Four-season comfort in a space that tended to overheat in the summer and be uncomfortable in the winter.
-
A compact solution that does not encroach on the passageway or the furniture.
-
A clean and discreet installation , integrated into the existing decor.
The hallway where we positioned the wall-mounted unit serves several rooms, allowing the air conditioning or heating to be distributed efficiently throughout the entire dwelling.
Choosing the Sharp wall-mounted heat pump
For this project, we recommended a Sharp wall-mounted heat pump from the ZU1 series, 12,000 BTU, R-32 refrigerant .
This choice can be explained by several reasons:
-
High energy efficiency , ideal for reducing Hydro-Québec bills.
-
Excellent heating performance in cold weather , perfectly suited to Montreal winters.
-
Quiet operation , essential in an apartment where the indoor unit is located close to the bedrooms.
-
Simple and compact design , which integrates harmoniously with the upper wall, above the wardrobe.
The Sharp brand is known for its reliable, efficient and easy-to-maintain wall units, making it an excellent long-term investment for both homeowners and renters.
Interior installation details
Wall-mounted head positioning
We installed the Sharp heat pump unit high up, above the closet door. This positioning offers several advantages:
-
It completely frees up the floor space and side walls , which are already occupied by doors and storage.
-
It allows for uniform air distribution in the corridor and adjacent rooms.
-
The height facilitates the mixing of hot and cold air , limiting areas of drafts or overheating.
The directional air supply louvers can be adjusted to direct air either towards the bedrooms or towards the main living area, offering the customer great flexibility of use.
Wall control integration
On the side wall, we installed a simple and intuitive wall-mounted controller . It allows you to:
-
Quick selection of heating, cooling, dehumidification and ventilation modes.
-
Programming the desired temperature for stable comfort.
-
Easy access for all occupants, without having to search for the remote control.
This combination of remote control and wall control enhances the system's ergonomics and limits unnecessary handling.
Routing of conduits and finishing
Behind the Sharp wall head, the refrigerant lines, condensation drain and wiring pass through the wall to reach the outdoor unit (not visible in the photo).
Our teams paid particular attention to:
-
Minimize the length of the path to limit pressure losses and optimize system performance.
-
Ensure the ducts are properly sealed and insulated to prevent condensation or cold air infiltration.
-
Use discreet trims and covers , in harmony with the wall color, for a clean and professional finish.
The result: the system is virtually invisible in the customer's daily life, while offering comfort felt from the first minutes of operation.
Comfort and performance in winter as well as summer
With its Sharp wall-mounted heat pump, the customer now benefits from:
-
For rapid cooling during the heat and humidity episodes of the Montreal summer.
-
Efficient and economical heating during the cold season, as a supplement to or replacement for your old electrical appliances.
-
Improved indoor air quality , thanks to the integrated filtration of the wall head.
The central location in the dwelling reduces temperature variations from room to room, making the apartment much more comfortable and pleasant to live in.
