In Rosemont–La Petite-Patrie, red brick duplexes are a common sight in Montreal. In this type of building, improving comfort while preserving the aesthetic appeal of the facade is a real challenge. This is precisely the objective of this project, where our AirGreen team installed a Sharp Eco Inverter wall-mounted heat pump , providing uncompromising four-season comfort.
Context: Modernizing the comfort of a brick duplex
The client, owner of a residential duplex, wanted:
-
Replace noisy and inefficient air conditioning solutions;
-
Add efficient heating to reduce reliance on electric baseboard heaters;
-
Choose a discreet installation, suitable for a brick facade visible from the courtyard;
-
Opt for a brand recognized for its reliability and air quality.
We recommended a Sharp Eco Inverter wall-mounted heat pump, perfectly sized for the area to be served. Inverter technology, high energy efficiency, and quiet operation make it an excellent choice for an urban environment like Rosemont–La Petite-Patrie.
The chosen system: Sharp Eco Inverter wall-mounted heat pump
The installed system is a Sharp wall-mounted heat pump , consisting of:
-
From an indoor wall-mounted unit (mini-split) in the main living area;
-
From a Sharp Eco Inverter outdoor unit installed on the brick facade, on wall brackets;
-
With a capacity of approximately 12,000 BTU , typical of Sharp ZU1 Eco Inverter models, ideal for a medium-sized home.
Key features of the Sharp system:
-
Eco Inverter technology : the compressor speed adjusts continuously, allowing for a stable temperature, fewer start-up cycles and energy savings;
-
Excellent performance in air conditioning in the summer and in heating at low temperatures, adapted to the Montreal climate;
-
Improved air quality thanks to Sharp's proprietary advanced filtration;
-
Quiet operation , both inside and out, is essential in a dense neighbourhood like Rosemont–La Petite-Patrie.
The photo also shows another outdoor unit installed further along the same wall, illustrating a configuration where each dwelling has its own wall-mounted heat pump , guaranteeing personalized comfort.
Installation details visible on the brick facade
The installation of this Sharp heat pump highlights several best HVAC practices:
1. Sturdy wall brackets
The outdoor unit is mounted on galvanized steel wall brackets securely anchored in the brick. This solution allows for:
-
To clear the unit from the ground to protect it from snow, ice and debris;
-
To reduce the risks of corrosion related to contact with moisture and rubble;
-
To free up floor space, while facilitating maintenance around the building.
The supports are installed at an optimal height : high enough for snow accumulation, but low enough to allow easy access during maintenance work.
2. Runoff and soil management
At the foot of the wall, a bed of river stones covers the ground. This detail serves both an aesthetic and a practical purpose:
-
It promotes water drainage , including water from defrosting the unit in winter;
-
It limits mud splashes on the facade;
-
It helps to maintain a clean environment around the device.
This combination of brick facade + stone bed integrates very well with the style of Rosemont's interior courtyards.
3. Refrigeration lines and power supply
We can distinguish:
-
The casing of the refrigeration lines which runs neatly towards the inside;
-
An electrical junction box installed near the outdoor unit, in accordance with applicable standards.
This attention to detail in the routing of the cables and conduits:
-
Protects components against shocks and weather;
-
Makes it easier to locate during a future interview;
-
It offers a clean visual finish, important for an owner who cares about the appearance of their building.
Project progress with AirGreen
1. Needs assessment and sizing
During the first visit, we:
-
Analyzed the configuration of the plex, the insulation and the orientation of the rooms;
-
Checked the condition of the brick facade and the ground;
-
Determined the ideal capacity of the Sharp wall-mounted heat pump to ensure efficient heating and cooling.
This sizing step is crucial: an oversized or undersized device is less comfortable, less efficient and more expensive in the long run.
2. Choice of indoor and outdoor location
Inside, the wall-mounted head unit was positioned so that:
-
Cover the main living area ;
-
Ensure good air circulation without direct drafts on the occupants;
-
Minimize the length of the pipes to the outside.
Outside, the location of the Sharp unit was chosen for:
-
Respect the required clearances around the device;
-
Reduce the visual impact from the street;
-
Limit noise pollution for the neighbors.
3. Installation, vacuuming and commissioning
Our certified technicians then:
-
Pierced the facade for the passage of pipes, respecting the integrity of the brick;
-
The outer casing was carefully installed and sealed;
-
Attached the wall brackets, then the Sharp Eco Inverter unit;
-
Connected the refrigeration lines, the drain, and the power supply;
-
Performed a rigorous vacuum test , then tested the system's leak-tightness;
-
The heat pump was put into service by checking the pressures, intensity, blowing temperatures and the response of the unit in heating and cooling modes.
We concluded by training the client on:
-
Using the Sharp remote control;
-
Recommended styles according to the season;
-
Best practices for optimizing the lifespan of the device.
