In Montreal's Southwest borough, backyards are often compact, shared between wooden decks, stairs, and small storage spaces. Installing a heat pump in this context requires a thoughtful approach to balance performance, quiet operation, and aesthetics. This is precisely what we achieved here with the installation of a Sharp Eco Inverter wall-mounted heat pump .
A typical Montreal plex project
The client lives in an apartment in a typical Southwestern brick building: masonry facade, wooden backyard, stair access, and limited space for mechanical equipment. His objectives were clear:
-
Replacing an inefficient heating system.
-
Add air conditioning to get through the summer heat waves.
-
Install a reliable, quiet and discreet device, without encroaching on outdoor living space.
We recommended a Sharp ZU1 series wall-mounted heat pump, 18,000 BTU, Eco Inverter , perfectly suited to cover the main living area of the dwelling while respecting the site constraints.
System type: Sharp Eco Inverter wall-mounted heat pump
The installed system is a wall-mounted heat pump (mini-split) consisting of:
-
With a Sharp wall head inside (silent horizontal wall unit).
-
From an outdoor Sharp Eco Inverter condenser , visible in the photo, installed in the backyard.
This type of system offers several advantages for residences in the Southwest:
-
Heating and air conditioning with a single unit .
-
Inverter technology : the compressor continuously adapts its power, which reduces frequent starts/stops and decreases consumption.
-
Flexible installation : ideal for existing homes where adding air ducts would be complex.
An outdoor positioning optimized for the Montreal climate
Installation on a raised support
The Sharp Eco Inverter outdoor unit was installed on a raised metal stand :
-
Clearance from the terrace floor to avoid any direct contact with snow, ice and standing water.
-
Protection against snow accumulation during winter storms.
-
Improved drainage of defrost water, visible on the ground under the unit.
This galvanized steel support ensures exemplary mechanical stability and limits the transmission of vibrations to the building structure.
Compliance with clearances and air circulation
Despite the proximity of the brick and acrylic-clad walls, we have:
-
Maintained sufficient clearance at the rear and sides of the condenser.
-
Maintain a large free space in front of the fan grille to allow optimal air circulation .
-
Position the unit in a corner that frees up passage on the terrace while remaining easily accessible for maintenance.
This configuration ensures the proper functioning of the heat pump even during high heating demands in the middle of winter.
Power supply and connection management
In the photo, we can see:
-
An electrical disconnect box installed near the unit, in accordance with Quebec standards.
-
The power cable is protected and neatly routed.
-
The refrigeration pipes and drain are routed inside through the building wall, with an adequate slope for water drainage.
We pay particular attention to these details in order to guarantee safety, reliability and ease of service .
Performance of the Sharp Eco Inverter in winter and summer
A heat pump installed in Montreal must contend with:
-
Harsh winters , often below -20°C.
-
Increasingly hot summers , with high humidex values.
The Sharp Eco Inverter wall-mounted heat pump addresses these challenges thanks to:
-
A high-efficiency compressor , capable of providing stable heating even when the outside temperature drops.
-
An intelligent defrosting mode , which limits the formation of ice on the outdoor unit and ensures continuous heating.
-
High-performance and quiet air conditioning in summer, with precise control of the indoor temperature and multiple fan speeds.
-
Reduced electricity consumption compared to electric baseboard heaters or a traditional air conditioner.
For the customer, this translates into four-season comfort and reduced energy costs , especially when the heat pump is primarily used for heating.
Integration into the backyard and noise reduction
In a neighborhood like the Southwest, the proximity to neighbors and the small size of the courtyards require controlled noise levels and careful visual integration .
-
The Sharp condenser has been oriented to direct airflow and noise away from the most frequently used doors and windows.
-
Eco Inverter technology allows operation at reduced speed most of the time, which limits perceived noise.
-
Positioning it on the terrace, near the wall, remains visually discreet , while leaving enough space to move around and enjoy the outdoors.
Thus, the customer can enjoy their terrace without being bothered by the equipment, even when the heat pump is running continuously.
A turnkey project by AirGreen
As with each of our Sharp wall-mounted heat pump installations in Greater Montreal, we offered a complete service:
