In this project, located in a modern condo in Southwest Montreal , our AirGreen team was tasked with ensuring year-round comfort in a bright, high-ceilinged room that was difficult to maintain at a stable temperature. The space, situated on the upper floor, features a narrow, high window and pristine white walls: the perfect location for aSharp wall-mounted heat pump , provided it is carefully integrated.
We therefore installed a Sharp TU 12,000 BTU wall-mounted heat pump , a compact, efficient solution perfectly suited to the recent condos in this rapidly changing area.
A bright condo, but prone to temperature fluctuations
Southwest Montreal is characterized by a combination of repurposed industrial buildings and new construction. Here, the client lives in a recently built condo with:
-
high ceilings
-
A horizontal window in the upper part , which lets in a lot of light.
-
White walls that reflect natural light
but also :
-
a significant increase in heat during the summer due to sunshine,
-
a feeling of cold near the walls during the windiest winter days.
The original electric heating was no longer sufficient to provide the desired comfort, especially in this room used both as a bedroom and a home office . The client wanted:
-
a silent system,
-
capable of providing efficient heating in winter ,
-
to cool down quickly in the summer ,
-
while maintaining a clean aesthetic compatible with the minimalist style of the condo.
The chosen solution: Sharp TU wall-mounted heat pump
After a detailed assessment of the heating requirements and room layout, we recommended:
-
System type: Single-zone wall-mounted heat pump (mini-split)
-
Brand: Sharp
-
Model: Sharp TU 12,000 BTU, R-32 refrigerant
This model stands out because of:
-
excellent energy efficiency , ideal for reducing electricity costs;
-
stable performance during the typical cold winters of Montreal;
-
a very efficient air conditioning function , particularly useful in condos with lots of windows;
-
ultra-quiet operation , perfect for a bedroom or office.
Indoor unit integration: under the window, at the correct height
The photo shows the Sharp wall unit installed directly under the high window. The louvers are open, indicating that the system is working and distributing air into the room. This positioning was carefully chosen for several reasons:
-
Optimizing air circulation
-
Installed in the upper part, the heat pump allows for good circulation of the hot air accumulated near the ceiling.
-
In air conditioning mode, the cool air is efficiently distributed throughout the room, without direct drafts on the bed or workstation.
-
-
Respect for aesthetics and architectural lines
-
The unit follows the line of the window and integrates with the modern design of the wall.
-
The white of the device blends in with the paint, giving an impression of visual continuity.
-
-
Intelligent use of space
-
The area under the window is not very usable for furniture; installing the heat pump there therefore frees up the rest of the walls for storage or decoration.
-
The indicator lights on the right side of the unit allow the customer to immediately see the operating status, while the simple and smooth front panel remains discreet even when the device is in operation.
Technical details and installation constraints
Installing a Sharp wall-mounted heat pump in this condo in the Southwest required managing several technical aspects:
-
Significant mounting height
-
The unit is located near the ceiling, under the high window.
-
We used a precise fixing template to ensure perfect leveling, despite the height.
-
-
Passage of refrigerant lines
-
The refrigerant pipes, wiring and condensate drain are run behind the unit, then guided outwards with a discreet finishing cover (not visible in the photo, opposite side).
-
This route was studied to minimize the length of the links , which improves the overall efficiency of the system.
-
-
Condensate management in air conditioning
-
A drain was installed with an adequate slope to remove the water produced in air conditioning mode, preventing any trace of moisture on the wall.
-
Depending on the configuration, a condensate pump may be provided, but in this case, gravity was sufficient.
-
-
Compliance with electrical standards
-
The Sharp outdoor condenser was connected to a dedicated circuit, in accordance with the Quebec Electrical Code.
-
Communication between the indoor and outdoor units was verified with comprehensive tests during commissioning.
-
Implementation steps by AirGreen
As with all our wall-mounted heat pump projects, we followed a structured process:
-
Analysis and dimensioning
-
Calculation of thermal load based on volume, orientation and level of insulation.
-
Feasibility check (location for the indoor unit and the outdoor unit on the balcony or on the facade).
-
-
Site planning
-
Choosing the wall under the high window to take advantage of natural air circulation.
-
Validation with the client of the visual rendering and future constraints (curtains, furniture, etc.).
-
-
Installation of the Sharp TU indoor unit
-
Securing the mounting plate to a solid support.
-
Installation of the unit, connection of the links, mechanical testing.
-
-
Installation of the outdoor condenser
-
Place the Sharp outdoor unit on a stable and clear surface, with clearances in accordance with the instructions.
-
Protection against snow and ice where relevant (raised support, clearance on the air exhaust side).
-
-
Vacuum sealing and testing
-
Vacuuming the refrigeration circuit.
-
Leak testing and validation of the R-32 refrigerant charge.
-
-
Commissioning and customer training
-
Explanation of the different modes: Heat (heating) , Cool (air conditioning) , Dry (dehumidification) , Fan (ventilation) and Auto .
-
Tips for getting the most out of your heat pump: recommended temperatures, programming, basic maintenance (cleaning the filters).
-
Benefits for the client in this Southwest condo
Since the installation of the Sharp TU 12,000 BTU wall-mounted heat pump , the customer has been enjoying:
-
A stable temperature in all seasons : less overheating in summer and more “cold spots” in winter.
-
Cleaner and drier air , particularly welcome during periods of high humidity.
-
Very quiet operation , compatible with teleworking and sleep.
-
Energy savings compared to traditional electric heating, thanks to the high efficiency of the heat pump.
The unit blends perfectly into the modern decor of the condo: the presence of the tall window and the white wall highlights the simplicity of the Sharp line, without giving an impression of overload.
