In the heart of the Plateau-Mont-Royal, in a typical Montreal brick building, our AirGreen team completed the full installation of aSharp wall-mounted heat pump . The client's objective was clear: to enjoy year-round comfort in their home, while maximizing energy efficiency and preserving the aesthetics of the facade.
A typically Montreal context
The building is located in an alley in the Plateau district, with its red brick walls and stacked apartments. As is often the case in this type of building:
-
The ground space is limited at the rear, with an area of decorative rocks along the foundation.
-
The facades are visible from the courtyard or the alley, which requires a clean and discreet assembly .
-
Tenants need a quiet and efficient air conditioning system in the summer and a heating system in the shoulder seasons, or even in the middle of winter.
In this context, the most suitable solution was a Sharp Eco Inverter wall-mounted heat pump , installed on an outdoor wall bracket and connected to an indoor wall head.
System choice: a Sharp Eco Inverter heat pump
We recommended a Sharp ZU1 series wall-mounted heat pump, 12,000 BTU – a classic for Plateau apartments:
-
Inverter technology to modulate power and reduce energy consumption.
-
Efficient heating capacity in cold weather , ideal for Montreal's climate.
-
Compact, quiet compressor, designed to be forgotten in everyday use.
-
Integration of Sharp's proprietary technologies, including air treatment by Ion Plasmacluster , contributing to improved indoor air quality.
This choice allows the client to benefit from a system that is reliable, efficient and economical , while respecting the constraints of the existing building.
Outdoor unit installation details
In the photo, we see the Sharp Eco Inverter outdoor unit securely mounted on galvanized steel wall brackets . Several technical points are important:
-
High mounting : the device is installed above the foundation line, which protects it from snow, ice and splashes in winter.
-
Clearances respected :
-
Sufficient space behind the unit for air circulation,
-
Front clearance to allow for good fan sweep
-
adequate distance from the ground to facilitate maintenance.
-
-
Consoles sized to support the weight of the device and limit vibrations on the brick.
The refrigerant pipes are carefully guided along the wall and then covered to their destination. The passage for the electrical cable and the condensation drain is also visible; these will all be secured and protected once the commissioning tests are complete.
To the right of the unit, another condenser is visible, illustrating the density of equipment often found in the Plateau's backstreets. Our role is to coordinate the placement to avoid any conflicts with exhaust air and to comply with installation standards.
Professional vacuum sealing and commissioning
With their backs against the wall, our team installed a manifold connected to the heat pump, as well as a vacuum pump . This step is crucial:
-
Vacuuming of the refrigeration circuit
The vacuum pump removes air and moisture from the pipes and indoor unit. A clean, dry system is essential for:-
to prevent internal corrosion,
-
prevent ice from forming in the regulator,
-
to ensure the longevity of the compressor.
-
-
Leak test
Using the manifold, we verify that the system maintains a stable vacuum. In case of loss, we can immediately detect and correct any leaks at a fitting. -
Opening the refrigerator and performing functional tests
Once the checks are complete, the refrigerant contained in the Sharp unit is released into the circuit. We then test:-
the operating pressure ,
-
the blowing temperature ,
-
the behavior of the heat pump in cooling and heating modes.
-
This rigorous process ensures commissioning in accordance with standards and guarantees optimal performance from day one.
Integration with the indoor unit
Although not visible in this photo, the outdoor unit is connected to a Sharp wall-mounted unit installed high inside the dwelling. This indoor/outdoor combination allows for:
-
rapid air conditioning of rooms in summer.
-
comfortable and stable heating during the cold season,
-
quiet operation, particularly appreciated in bedrooms or home office spaces.
The refrigeration lines pass through the brick wall via a carefully made opening, which is then insulated to prevent air and moisture infiltration.
Four-season performance and comfort in Plateau-Mont-Royal
Thanks to this Sharp wall-mounted heat pump installation, the customer now benefits from:
-
of tailor-made comfort : stable temperature, filtered air, better controlled humidity;
-
reduced energy bills , as the heat pump uses electricity more efficiently than electric baseboard heaters or some older systems;
-
a versatile solution : a single device to cool in the summer and heat for much of the year, even in sub-zero temperatures.
In a neighbourhood like Plateau-Mont-Royal, where buildings are sometimes poorly insulated or heated unevenly, a properly sized Sharp heat pump represents a significant upgrade in residential comfort .
