Installation of a Sharp wall-mounted heat pump on a flat roof in Rosemont–La Petite-Patrie

In the leafy Rosemont–La Petite-Patrie neighbourhood, we had the pleasure of installing a Sharp Eco Inverter wall-mounted heat pump for a residential apartment building. The goal: to provide a high-performance, discreet heating and cooling system perfectly suited to the realities of Montreal's flat roofs.

Project context: four-season comfort for an urban building

The building is typical of Rosemont: several apartments, brick facades, green alleyways, large mature trees, and a flat roof offering a beautiful view of downtown. The co-owners wanted:

• Replacing aging and energy-inefficient equipment;

• Improving summer comfort during heat waves;

• Take advantage of the heat pump mode to reduce heating costs;

• Minimize noise and visual impact on the facade.

The ideal solution: a Sharp wall-mounted heat pump , installed directly on the roof, to free up floor space and preserve the aesthetics of the building.

Equipment choice: Sharp Eco Inverter wall-mounted heat pump

We opted for a Sharp Eco Inverter wall-mounted heat pump , a reliable residential range designed for climates like ours.

This type of system offers several advantages:

• Inverter technology : power modulation to maintain a stable temperature while reducing electricity consumption;

• Quiet comfort : reduced noise level both inside and outside;

• Heat pump function : a single unit provides gentle heating in mid-season and air conditioning in summer;

• Energy efficiency : ideal for reducing electricity bills compared to traditional systems.

The Sharp outdoor condenser visible in the photo is paired with one or more discreet indoor wall heads, installed in the served dwellings.

Installation on a flat roof: stability, durability and respect for the roof

Installing a heat pump on a flat roof requires a rigorous approach. We have designed a specially adapted elevated support structure :

• Galvanized steel frame fixed on distribution pads to protect the roof membrane;

• Supports made of treated wood to absorb vibrations and distribute the load;

• Elevated unit to promote water drainage, facilitate snow removal and protect the unit from the accumulation of ice or debris;

• Clearances respected all around the condenser to guarantee excellent air circulation and therefore the performance of the Sharp.

This approach ensures both the safety of the equipment and respect for the integrity of the roof , a crucial point for condominiums and owners of rental buildings.

Management of refrigeration connections and power supply

Invisible details often make all the difference in the lifespan of an installation. On this project, we paid particular attention to:

• Protection of refrigeration pipes in UV-resistant cable trays and covers;

• The insulation is carefully sealed to prevent water infiltration and premature degradation;

• The watertight passage through the roof for electrical connections and cables;

• The dedicated electrical connection , compliant with current standards, with a safety circuit breaker easily accessible for maintenance.

The result: a clean, organized installation, designed to last and to facilitate future maintenance interventions.

Performance and comfort for the residents of Rosemont–La Petite-Patrie

With this Sharp wall-mounted heat pump , the occupants now benefit from:

• With a cool, summery comfort , even on the hottest days in Montreal;

• Efficient and uniform heating in spring and autumn, as a complement to or replacement for existing systems;

• It operates silently , both inside the apartments and on the roof, which is valuable in a dense neighborhood like Rosemont;

• Reduced energy bills thanks to the high efficiency of Inverter technology.

The machine is sized to offer a balance between power, comfort and economy, while remaining discreet in the urban landscape.

Safety, maintenance and longevity of the Sharp heat pump

At AirGreen, we know that a good installation doesn't end on commissioning day. For this project:

• We carefully checked the refrigerant pressures and Sharp operating parameters;

• We provided the client with all the information on preventive maintenance (cleaning of filters, clearances around the unit, periodic inspections);

• We offer regular maintenance visits to ensure optimal system performance year after year.

A properly installed and well-maintained heat pump is an investment that pays for itself quickly, especially in a climate like Montreal's.
