For this project in the Plateau-Mont-Royal neighbourhood , our team was tasked with modernizing the heating and air conditioning system of a condominium building located on a typical Montreal street, with flat roofs and unobstructed city views. The goal: to provide year-round comfort while reducing energy consumption, all with a clean, durable, and discreet installation.
We recommended and installed a Sharp wall-mounted heat pump , Eco Inverter range, a system recognized for its reliability, energy efficiency and quiet operation, perfectly suited to the dense urban context of the Plateau.
Project context: an urban condominium on a flat roof
The building is a condominium with several units , with the available space primarily on the roof. As is often the case in Plateau-Mont-Royal, the challenge is twofold:
-
Limit noise for the occupants and the neighborhood;
-
Preserve the aesthetics of the building, visible from the neighboring roofs and terraces.
The chosen solution was a flat-roofed installation of the Sharp condenser, connected to indoor wall units in the apartments. This type of configuration completely frees up facades and balconies, while providing excellent airflow around the equipment.
Choosing the Sharp Eco Inverter wall-mounted heat pump
For this project, we installed a Sharp Eco Inverter wall-mounted heat pump , from the same family as the high-performance Sharp ZU1 series, known for its efficiency in heating and cooling mode.
The advantages of the Sharp system for this customer
-
Inverter technology : the compressor finely modulates its speed, ensuring stable comfort, fewer temperature variations and reduced energy consumption.
-
Quiet operation : an essential criterion on a roof shared between several dwellings; noise is minimized for immediate neighbors.
-
Improved air treatment : Advanced filtration technology (including Ion Plasmacluster air treatment visible on the unit) contributes to better indoor air quality.
-
Four-season reliability : the heat pump provides summer cooling and supplementary heating in the off-season , thus relieving the main appliances and reducing energy costs.
A flat roof installation designed to last
1. Sharp condenser on raised supports
The Sharp outdoor condenser has been installed:
-
On raised metal supports , securely anchored;
-
With anti-vibration pads under each foot, visible in the photo, to reduce vibrations transmitted to the structure;
-
At a sufficient distance from other devices on the roof, in order to optimize air circulation and facilitate maintenance.
This approach ensures excellent mechanical stability and protects the equipment against the accumulation of water or snow on the roof.
2. Careful management of refrigeration lines
The refrigeration lines and electrical cables were:
-
Protected in sheaths designed for outdoor use;
-
Transported in an orderly fashion onto the roof, respecting the existing slopes;
-
Securely fixed to prevent any friction or excessive movement in the wind.
This attention to the piping helps to extend the life of the system and reduce the risk of premature breakdowns.
3. Accessibility for maintenance
The chosen location leaves:
-
Sufficient clearance in front of the condenser grille for future maintenance;
-
A safe passage for AirGreen technicians during seasonal maintenance.
The result is a system that is easy to inspect, clean and maintain, which reduces service costs in the long run.
Performance and comfort in Montreal's climate
In Plateau-Mont-Royal, temperature variations are significant: humid heat waves in summer, and persistent cold in winter. The Sharp Eco Inverter wall-mounted heat pump is perfectly suited to this environment.
-
In summer , it provides efficient air conditioning for the main rooms, maintaining a pleasant temperature even during periods of intense urban heat.
-
In spring and autumn , it provides very economical supplementary heating , allowing the main systems to be switched on later and reducing the energy bill.
-
In winter , the Sharp heat pump contributes to indoor comfort on milder days, while remaining an ideal complement to existing heating systems.
Thanks to Inverter modulation, the system avoids frequent starts, which improves comfort, increases the machine's lifespan and reduces electricity consumption.
A clean, safe and discreet construction site
On this flat roof, typical of the Plateau-Mont-Royal, it was essential to:
-
Minimize visual clutter ;
-
Ensure that the loads on the roof are properly distributed;
-
Respect clearance and safety standards around equipment.
Our installers worked in coordination with the condominium association in order to:
-
Confirm the location of each condenser;
-
Plan a secure passage for future access;
-
Leave the work site clean, without debris or unnecessary exposed cables.
The result: a clean, professional installation that blends perfectly into the urban environment of the Plateau.
