In this cozy living room in Montreal's Villeray neighbourhood, our team was tasked with improving the year-round comfort of a typical apartment: standard ceilings, semi-open-concept rooms, and a living area heavily used by the family. The chosen solution? The installation of a modern, discreetSharp wall-mounted heat pump , perfectly integrated into the interior architecture.
Context: a lively living room that needed real comfort
The client wanted:
-
Effective air conditioning in the summer , to eliminate episodes of stifling heat.
-
Efficient heating in the shoulder seasons and in winter , to reduce reliance on electric baseboard heaters.
-
A silent system, compatible with everyday use in the living room (television, relaxation, teleworking).
-
An aesthetically pleasing installation, without visible cable trays or unsightly conduits on the walls.
The living room features a light-colored main wall with a geometric recess (like a stairwell or structural alcove) and dark furniture, including a leather armchair. The idea was to use this wall as the main focal point for the interior headboard, while maintaining the clean lines of the room.
The choice: a Sharp ZU1 wall-mounted heat pump
To meet these needs, we opted for a Sharp wall-mounted heat pump , ZU1 series, an R-32 model that is very popular for Montreal homes:
-
Capacity around 12,000 BTU , ideal for a medium-sized living room and adjoining rooms.
-
Inverter technology : the device modulates its power and avoids frequent on/off cycles, which increases comfort and durability.
-
R-32 refrigerant , more efficient and more environmentally friendly than older refrigerants.
-
Efficient heating mode in cold weather , perfectly suited to Villeray winters.
-
Quiet operation , perfect for a relaxation or TV corner.
The Sharp brand is part of our regular offering of wall-mounted heat pumps at AirGreen, recognized for its good value for money and reliability in a Quebec residential context.
Indoor unit positioning: efficiency and design
The photo shows the Sharp wall unit installed high on the main wall , just below the ceiling, with the recess in the bottom right corner. This choice is not arbitrary:
-
By placing it high up, we allow fresh or warm air to distribute naturally throughout the room.
-
The wall is clear: no furniture blocks the airflow, ensuring even distribution in the living room.
-
The recess in the wall creates a framing effect around the heat pump, resulting in a very clean and modern look.
-
The unit is aligned with the ceiling and wall lines, allowing the device to blend into the decor rather than attracting attention.
The result: discreet equipment that is visually unobtrusive, but very much present when it comes to comfort.
Technical details of the installation
As with all our installations, we have followed best HVAC practices and manufacturer recommendations:
-
Wall bracket sized for the Sharp ZU1 heat pump, securely attached to the wooden studs of the partition.
-
Drilling through the exterior wall (on the other side, facade or courtyard side), with a controlled angle to promote the flow of the condensation drain.
-
Refrigeration lines and electrical cable are routed in a compact and insulated manner to avoid heat loss and vibration noise.
-
Condensation drain installed with a constant slope, ensuring efficient drainage of water produced in air conditioning mode, without risk of drips or stains on the wall.
-
Connection to the outdoor unit (not visible in the photo), positioned in a strategic location outside, respecting regulatory clearances and facilitating future maintenance.
We also took care to limit the traces of installation : once the tests were completed, the small marks on the wall were cleaned, and if necessary, the client could lightly refresh the paint for an absolutely perfect finish.
Commissioning and checks
After the mechanical installation comes a crucial step: the professional commissioning of the heat pump.
Our technicians have:
-
A complete vacuum was drawn on the refrigeration lines to remove air and moisture.
-
Checked the refrigeration circuit for leaks to prevent any refrigerant leaks.
-
Measured pressures and temperatures in air conditioning and heating modes to confirm that the Sharp ZU1 is operating within its optimal parameters.
-
The drain flow has been verified to be working properly .
-
Configured the operating modes (auto, heating, air conditioning, ventilation) with the client, and explained the best practices for use.
We always take the time to show the owner how to use their remote control, how to adjust the temperature, airflow, shutter direction, and how to make the most of the advanced functions (night mode, programming, etc.).
Benefits for the customer in Villeray
Since the installation, the customer has benefited from:
-
Significantly improved summer comfort : no more stifling living room during Montreal heat waves.
-
A very efficient supplementary or main heating system in autumn, spring and even in the middle of winter, which often allows for a reduction in the consumption of electric baseboard heaters.
-
A reduction in electricity bills , thanks to the superior efficiency of the Sharp heat pump compared to purely electric heating.
-
A very low noise level : the wall unit remains discreet, even in the evening in front of the television.
-
Added value to the property : the presence of a recent wall-mounted heat pump is a concrete asset when reselling or renting.
