In Rosemont–La Petite-Patrie, families are increasingly seeking heating and cooling solutions that are efficient, quiet, and economical. In this project, our AirGreen team was tasked with replacing an old, energy-inefficient electric system with a Sharp wall-mounted heat pump featuring ECO Inverter and Ion Plasmacluster technology , perfectly suited to Montreal's climate and the realities of the typical plexes in this neighbourhood.
Context: a wooden balcony, a brick facade, and limited space
The client lives on the ground floor of a brick duplex with a wooden rear balcony. The main constraints are:
-
Limited space on the terrace: it was necessary to maintain space for circulation and outdoor furniture.
-
Brick facade opening directly onto the balcony, without a cement strip on the floor.
-
A tap and a garden hose are located nearby and must be used for grounds maintenance.
-
Close proximity : the condenser had to remain very quiet to preserve quality of life.
Our solution: the installation of a Sharp single-zone wall-mounted heat pump , from the residential ECO Inverter range (typical configuration of a Sharp ZU1 model), mounted on a raised support to optimize clearances and durability.
Why a Sharp wall-mounted heat pump in Rosemont?
Sharp wall-mounted heat pumps stand out because of:
-
Their Inverter technology modulates power instead of operating in on/off mode, thus reducing energy consumption and temperature variations.
-
The Ion Plasmacluster system, which helps to purify the air by neutralizing certain particles and odors – a major advantage in urban dwellings where one wants to limit the opening of windows onto a busy street.
-
Quiet operation , both for the indoor unit and the outdoor condenser, ideal for the alleys and backyards of Rosemont.
In this project, the heat pump is sized to offer excellent comfort in the main living area (open-plan living room, dining room and kitchen), while also providing a significant boost in the adjacent rooms.
Technical details of the outdoor installation
A well-positioned Sharp condenser
The Sharp ECO Inverter condenser has been:
-
Installed on a raised galvanized steel support , securely fixed to the wooden floor of the balcony.
-
Positioned at a sufficient distance from the brick wall to ensure good rear clearance and facilitate air circulation.
-
Slightly off-center from the patio door to free up the passage area and minimize the visual impact from the inside.
The raised support allows for:
-
To protect the condenser from snow, ice and standing water on the terrace.
-
To reduce the risk of mechanical shocks (shovels, objects, furniture).
-
To facilitate drainage and cleaning under the unit.
We systematically use suitable brackets and anchors , with vibration damping to limit the transmission of structural noise to the balcony and, consequently, to the building structure.
Connections and power supply
In the photo, we can see:
-
A dedicated power supply in an external enclosure, compliant with the Electrical Code, in the immediate vicinity of the condenser.
-
Neat management of cables and refrigeration connections , discreetly routed into the dwelling.
-
Respecting clearances from the outdoor tap and garden hose , in order to maintain accessibility for watering and maintaining the terrace.
Everything is designed to ensure that the installation is efficient, safe and aesthetically pleasing .
Details of the indoor installation (Sharp wall head)
Inside, a Sharp wall-mounted mini-split heat pump unit was installed:
-
On a central wall of the living area , allowing for uniform distribution of air conditioning in summer and hot air in winter.
-
At an optimized height to ensure good room sweeping, while avoiding direct blasts on the occupants.
-
With a carefully planned condensate drainage system to avoid any risk of leaks or water damage.
The ECO Inverter + Plasmacluster combination offers the customer:
-
A very stable level of comfort , without unpleasant drafts, hot or cold.
-
Improved air quality , thanks to air treatment by Sharp's specific ionizing module.
-
Intuitive operation via remote control, with different modes (heating, air conditioning, dehumidification, ventilation).
Winter performance: ready for Montreal's climate
Even though Rosemont–La Petite-Patrie is in the heart of Montreal, the climate is anything but mild: bitter cold, freezing rain, and rapid temperature changes. The Sharp wall-mounted heat pump installed here is designed for:
-
Maintaining a good heating capacity even in cold weather , thanks to Inverter technology and compressor optimizations.
-
Significantly reduce the use of auxiliary heating systems (electric baseboard heaters, convectors), resulting in recurring savings on the electricity bill.
-
Offering increased reliability , provided that regular maintenance is carried out (cleaning of internal filters, inspection of the condenser, removal of snow).
Aesthetics, acoustic comfort and neighborhood
In the alleyways and backyards of Rosemont, outdoor units are often very visible and close to neighbors. Therefore, we paid particular attention to:
-
The visual alignment of the condenser with respect to the brick facade.
-
Noise reduction : dampened support, silent Sharp condenser, instructions to the customer for night programming.
-
Circulation around the unit : the condenser is sufficiently clear to allow maintenance of the balcony and brick cladding.
The result: a discreet system that blends well into the decor and does not disturb the occupants or the neighborhood.
The benefits for the customer
Following the installation of this Sharp wall-mounted heat pump in Rosemont–La Petite-Patrie , the client now benefits from:
-
Four-season comfort : efficient air conditioning in summer, efficient heating in the shoulder seasons and winter.
-
Substantial energy savings compared to heating with electricity alone.
-
With improved air quality , thanks to Ion Plasmacluster technology.
-
A safe, clean and durable installation , carried out by a certified team that is fully aware of the realities of Montreal buildings.
