In Mercier–Hochelaga-Maisonneuve, our teams were tasked with improving the comfort of a typical brick building in the neighbourhood. The occupants wanted an efficient air conditioning system for the summer, but also a high-performance, economical heating system to cope with Montreal winters. We therefore recommended and installed aSharp wall-mounted heat pump , from the Sharp ZU1 series, perfectly suited to this type of building.
The context: an urban building that needed 4-season comfort
The building is situated along an asphalt driveway, with a long, exposed brick wall: an ideal environment for a well-ventilated outdoor installation. Before our intervention, heating relied on a traditional, inefficient system, and there was no air conditioning. The result:
-
Difficult summers, with rooms overheating in the afternoon;
-
Costly winters, with high energy consumption;
-
Uneven comfort between the different floors.
The client's objective was clear: to gain comfort , reduce energy bills and install a discreet system that integrates neatly into the building's architecture.
Why a Sharp wall-mounted heat pump?
We directed this project towards a Sharp wall-mounted heat pump , from the Sharp ZU1 range, a particularly relevant choice for urban residential use in Montreal.
The advantages of the Sharp ZU1 range
-
High energy efficiency : a heat pump that offers excellent performance in both air conditioning and heating.
-
Next generation R-32 technology (ZU1 range): a more efficient and environmentally friendly refrigerant than the old R-410A.
-
Winter performance : designed to continue heating even in cold weather, making it suitable for Montreal's climate.
-
Silent operation : both inside and outside, the system remains discreet, which is essential in a dense neighbourhood like Mercier–Hochelaga-Maisonneuve.
In summary, the Sharp wall-mounted heat pump perfectly meets the need for four-season comfort without skyrocketing electricity consumption.
A neat outdoor installation on a brick wall
The photo clearly shows the care taken to integrate the outdoor unit into the brick facade.
Positioning of the outdoor unit
We mounted the Sharp condenser on sturdy wall brackets , securely anchored to the masonry. This choice offers several advantages:
-
Ground clearance: better protection against snow, water and debris;
-
Optimal air circulation around the unit, to maximize performance;
-
Maintenance is easier, since the machine is clear and accessible.
The height was chosen to comply with technical standards, safety and the aesthetics of the building.
Finishing channels matching the facade
The refrigerant lines, condensate drain, and electrical wiring are fully protected within dark brown exterior trunking. We deliberately followed the architectural lines of the building:
-
Vertical ascent along the brick wall;
-
Straight horizontal length;
-
Clean corner fittings, with no visible cables.
This finishing work allows for:
-
a very clean visual integration , which respects the style of the building;
-
durable protection against shocks, sun, snow and ice;
-
improved longevity of refrigeration lines .
Protection against inclement weather and the Montreal climate
In Mercier–Hochelaga-Maisonneuve, buildings are exposed to extreme temperature fluctuations, ice, and snow accumulation. Therefore, we paid particular attention to:
-
The unit's orientation to avoid the backflow of hot air towards walls or fences;
-
The clearance around the fan, so that the heat pump can breathe even in very cold weather;
-
Sealing the holes in the brick, in order to prevent any water infiltration .
The result: an installation ready to face many years of service, summer and winter.
The interior: comfort, silence and precise control
Although the photo shows the exterior, the heart of the comfort lies inside, where the Sharp wall-mounted head diffuses a homogeneous temperature throughout the room.
Immediate comfort
Thanks to its inverter technology, the heat pump adjusts its power in real time:
-
rapid temperature rise during periods of extreme cold;
-
effective cooling during heat waves;
-
Stable temperature maintenance without unpleasant fluctuations.
The occupants benefit from constant comfort , without sudden drafts or excessive noise.
Controlled electricity consumption
Compared to a conventional electric heater, the Sharp wall-mounted heat pump offers:
-
to significantly reduce energy consumption in winter;
-
to enjoy efficient air conditioning in the summer, without having to add a noisy window air conditioner;
-
to better control the energy budget, which is particularly interesting in Montreal where the heating season is long.
What this installation changes for our customers in Mercier–Hochelaga-Maisonneuve
With this new Sharp ZU1 wall-mounted heat pump , the building now benefits from:
-
of a four-season air conditioning and heating system adapted to Montreal's climate;
-
of a clean and discreet installation , which respects the aesthetics of the brick wall;
-
