Installation of a Sharp wall-mounted heat pump on a condo roof in Ville-Marie

For this project, our AirGreen team was contracted to install a system in a condominium building in the Ville-Marie district , in the heart of downtown Montreal. The owners wanted a high-performance heating and cooling system for their condo, while respecting the building's architectural constraints and the condominium regulations. We recommended the installation of a Sharp wall-mounted heat pump with Eco Inverter technology , with an outdoor unit installed on the roof.

A Sharp Eco Inverter wall-mounted heat pump suitable for a condo

The installed unit is a Sharp wall-mounted heat pump using Eco Inverter technology. This type of system is ideal for downtown condos because it offers:

• Efficient heating in winter and effective air conditioning in summer;

• Optimized power consumption thanks to Inverter technology, which continuously adapts the compressor's power;

• Quiet operation , essential in a condominium environment;

• Excellent four-season comfort , with stable temperature and precise control.

The Sharp condenser installed on the roof supplies one or more indoor wall-mounted units. This is a very common configuration in urban areas, where floor space is limited and the aim is to free up balconies and facades.

Roof choice for the outdoor unit: an advantage in urban environments

In a dense area like Ville-Marie , it is not always possible to install outdoor units on the ground or on balconies: lack of space, condominium regulations, aesthetic constraints or noise for immediate neighbors.

The solution chosen here is installation on the building's flat roof , on a gravel-covered area with an unobstructed view. This configuration offers several advantages:

• Optimal air clearance around the unit, which improves efficiency;

• Reduction of perceived noise in condo units, with the device being away from windows;

• Respect for the building's aesthetics , no apparent unity on the main facade;

• Simplified access for our technicians during maintenance and service interventions .

A carefully installed structure on a raised platform

The photo clearly shows the Sharp Eco Inverter condenser installed on a raised metal structure , itself resting on wooden beams on gravel. This approach was not chosen at random:

• The galvanized steel structure allows the unit to be maintained at a good height relative to the roof, which:

  • Facilitates the drainage of rainwater and snowmelt;

  • Reduces the risks associated with snow accumulation around the device in winter;

  • Provides better air circulation around the condenser.

• The wooden crossbeams distribute the load across the roof and protect the waterproofing membrane.

• Appropriate brackets and anchors ensure the stability of the assembly against the wind, which is particularly important on an exposed roof like this one.

Refrigeration lines and electrical cables are carefully bundled, insulated and protected, with particular attention paid to points of entry into the building to ensure the watertightness and durability of the installation.

Controlling Montreal's climate from the rooftops of Ville-Marie

Montreal's climate requires robust systems, especially when the outdoor unit is exposed on a roof:

• Strong winds at high altitudes;

• Snow and ice in winter;

• Episodes of intense heat in summer, with the roof able to accumulate a lot of heat.

The Sharp Eco Inverter heat pump was sized and installed to handle these constraints. In particular, we pay attention to:

• Respect the minimum clearances around the condenser to ensure proper ventilation;

• Position the unit at a sufficient height to limit the impact of snow and ice;

• Protect wiring and piping from UV radiation and temperature variations.

Thanks to these precautions, the system offers long-term reliability and maintains its energy efficiency season after season.

Interior comfort: quiet, stable and easy to control

Inside the condo, the Sharp wall-mounted unit(s) distribute cooled or heated air evenly throughout the rooms. Combined with the roof-mounted condenser, this configuration allows for:

• A very low noise level inside thanks to Inverter technology;

• A stable temperature , without large differences between day and night;

• Simple control via remote control or thermostat, often with time programming options;

• Optimized consumption , particularly interesting for owners who wish to reduce their energy costs while gaining comfort.

We always take the time to show occupants how to use the different modes (heating, air conditioning, dehumidification, ventilation) and how to adopt good practices to maximize the lifespan of the heat pump.

Customized maintenance and after-sales service

A system installed on a roof requires regular maintenance to maintain its maximum efficiency:

• Periodic cleaning of the condenser coils ;

• Checking the condition of the supports and fixings ;

• Checking the refrigeration circuit for leaks ;

• Inspection of the roof membrane around the structure.

At AirGreen, we offer a scheduled maintenance service tailored to condominiums and buildings in Ville-Marie and the city center. This helps prevent problems before they become costly and ensures consistent comfort for residents.
