As part of a recent project in Ville-Marie , in the heart of Montreal, our AirGreen team installed a Sharp wall-mounted heat pump on the roof of a residential building. This type of configuration, very common in central and dense areas like Ville-Marie, requires precise expertise from both a technical and regulatory standpoint.
A typical urban setting in Ville-Marie
The building in question is a flat-roofed building surrounded by other mechanical installations (ventilation, ductwork, existing units), a typical environment for condominiums and plexes in the city center. Given the limited ground space and the need to preserve the facade's aesthetics, installing the outdoor unit on the roof emerged as the most logical and sustainable solution.
This type of project is common in Ville-Marie, where municipal regulations, urban density and architectural constraints require discreet, efficient and well-integrated HVAC solutions.
Type of system installed
This is a wall-mounted heat pump (mini-split) , a perfect choice for urban dwellings, condos, and residential units without a central mechanical room. This type of system provides both heating in winter and cooling in summer , with excellent energy efficiency.
The wall-mounted heat pump offers:
-
Precise temperature control by zone
-
Quiet operation
-
A significant reduction in energy consumption
-
A flexible installation, even in existing buildings
Brand and model: Sharp, a reliable choice
The Sharp brand , supplied manually and used as the main reference, is recognized for the reliability of its HVAC systems and for the quality of its inverter compressors.
For this project, we selected a model consistent with Sharp's residential line, namely a Sharp ZU1 (R-32) wall-mounted heat pump . This series is particularly appreciated for:
-
Its high-modulation inverter technology
-
Its excellent energy efficiency
-
Its compatibility with the more environmentally friendly R-32 refrigerant
-
Its ability to maintain stable comfort, even during the temperature variations typical of the Montreal climate
Observable installation details and technical choices
The Sharp outdoor unit has been installed:
-
On an elevated steel structure , securely anchored
-
Resting on treated timbers , in order to distribute the load and protect the roof membrane
-
Keep at a safe distance from other mechanical equipment
-
With insulated refrigeration lines , grouped together and neatly routed into the building
-
By respecting the necessary clearances for optimal air circulation and unobstructed future maintenance
This type of rooftop installation requires particular attention to:
-
Vibration reduction
-
Weather protection
-
Accessibility for maintenance
-
Compliance with building standards and condominium association requirements
Our AirGreen team has extensive experience in this type of configuration, which is very common in Ville-Marie, Downtown and surrounding areas.
Performance and comfort in all seasons
Thanks to Sharp inverter technology, the system continuously adjusts its power according to the actual needs of the home. The result:
-
Efficient heating during cold periods
-
Stable and quiet air conditioning in summer
-
Fewer on/off cycles
-
Extended equipment lifespan
In an urban context where indoor comfort is paramount, especially in well-insulated buildings exposed to the sun and temperature variations, this type of wall-mounted heat pump is a wise choice.
