In this project in Rosemont–La Petite-Patrie, we installed aSharp wall-mounted heat pump on a typical Montreal brick duplex. The client's objective was clear: to improve year-round comfort while respecting the aesthetics of the facade and the constraints of a narrow passage between two buildings.
The context: a narrow passage between two buildings
The house is located in a very narrow side alley, with a red brick wall on one side and a wooden cladding on the other.
This type of environment imposes several constraints:
-
Limited floor space for installing a condenser on a slab.
-
Pedestrian traffic in the passageway to access the back yard.
-
Proximity to neighbors , which requires a discreet and quiet installation.
-
Direct exposure to the weather (snow, ice, rain) typical of Montreal winters.
We therefore opted for a fully wall-mounted solution, compact and perfectly suited to the realities of urban duplexes.
Equipment choice: Sharp ZU1 wall-mounted heat pump
For this project, we installed a Sharp ZU1 single-zone wall-mounted heat pump , a residential line known for:
-
its high energy efficiency ,
-
its stable operation in both heating and air conditioning ,
-
and its reliability in the Quebec climate.
Why a Sharp wall-mounted heat pump?
-
Ideal for main living areas (living room, dining room, open area);
-
Very quiet , which is important in a narrow alley and for the comfort of the neighbors;
-
Use of a new generation refrigerant, contributing to better energy performance;
-
Precise temperature control, summer and winter.
Inside, the wall-mounted head was positioned to effectively cover the main living area, while maintaining the shortest and most discreet possible pipe passage to the outside.
A neat and durable outdoor installation
The image clearly shows several key elements of a professional installation by AirGreen.
1. Condenser mounted on an elevated wall bracket
The Sharp condenser is installed on a robust wall bracket , securely fixed to the brick wall:
-
Sufficient height to protect it from snow, ice and splashes on the ground;
-
Adequate clearance at the rear and sides to ensure good air circulation ;
-
Freeing up floor space in the passageway allows for free movement and storage of wheeled bins without risk of impact against the device.
This mural approach is particularly relevant in dense neighbourhoods like Rosemont–La Petite-Patrie , where every centimeter counts.
2. Refrigeration pipes protected and integrated into the facade
The refrigeration lines and communication cables are:
-
Insulated and encased in a vertical technical cover in a color coordinated with the brick;
-
Securely attached to the wall , which avoids tension on the fittings;
-
Positioned to minimize visual impact from the street.
This type of finish is essential: a well-installed heat pump with a poor visual finish can detract from a building's overall appearance. Here, the installation blends seamlessly into the brick facade.
3. Compliant electrical box and protective devices
Below the condenser, we can also see:
-
An electrical disconnect box installed within easy reach for maintenance;
-
Clean, secure wiring that complies with local electrical standards .
These elements ensure the safety of the installation , facilitate maintenance interventions and extend the life of the system.
Four-season interior comfort
Thanks to this Sharp wall-mounted heat pump , the occupants now benefit from:
-
Effective cooling during summer heatwaves;
-
An efficient auxiliary heating system for the shoulder seasons and winter, allowing the main system to be relieved and the energy bill to be reduced;
-
Precise temperature control via remote control or advanced controls;
-
With quiet operation , ideal for a dense urban environment.
The device also contributes to better indoor air quality by filtering dust and particles, thus improving daily comfort.
An installation designed for Montreal's winter
Even though the photo was taken in the summer, the design of the installation takes into account harsh winters:
-
Sufficient height to avoid being buried in the snow;
-
Clear space around the condenser to allow air to circulate, even during significant accumulations;
-
Condensate drainage and defrosting are planned to prevent the formation of dangerous ice patches on the floor.
This proactive work is essential to ensure the reliability of the Sharp heat pump throughout the winter .
