Sharp wall-mounted heat pump installation in Verdun

In Verdun, on the rooftop terrace of a residential building overlooking the river, our team installed aSharp wall-mounted heat pump to provide year-round comfort for the occupants of an open-concept condo. The installation took place in an environment already equipped with several outdoor units, requiring a configuration that was efficient, safe, and aesthetically pleasing.

Context: a typical rooftop terrace in Verdun

The building is a typical multi-unit dwelling for the area: timber frame construction, large rooftop terrace, wooden railings, and unobstructed views. The client wanted:

• Replacing an old, noisy, and inefficient system;

• Maximize comfort in both summer and winter;

• Keep the terrace space usable and safe;

• Limit the vibrations transmitted to the building structure.

The choice of a Sharp wall-mounted heat pump emerged as an ideal solution for this type of urban building: heating performance, compact outdoor unit and proven reliability.

Choosing the Sharp wall-mounted heat pump

For this project, we opted for a Sharp ZU1 series wall-mounted heat pump , in the 18,000 BTU version, perfectly suited to a condo of approximately 900 to 1,000 sq ft with an open living-dining-kitchen area.

Among the advantages of this range:

• High energy efficiency technology , allowing for a significant reduction in electricity costs compared to older window air conditioners or basic electrical systems;

• Stable operation in heating mode in cold weather , suitable for Montreal's climate;

• Use of a new generation refrigerant that is more efficient and complies with current environmental standards;

• Reduced noise level , much appreciated in a dense urban living environment like Verdun.

A neat outdoor installation on the roof

The photo clearly shows several condensers installed on a gravel-covered roof. Our Sharp unit is positioned on galvanized steel supports resting on wooden beams laid on the membrane, which allows:

• to distribute the load and protect the roof membrane;

• to ensure adequate clearance under the unit for drainage and air circulation;

• to limit the transmission of vibrations to the structure.

Key features of our installation:

• Orientation of the unit to optimize airflow and maintain sufficient clearance from the guardrail and other condensers;

• Use of stainless and galvanized hardware , resistant to weathering and salt, particularly important near the river;

• Orderly routing of refrigeration lines (refrigerant), condensation drain and power supply, in order to reduce the risk of machining of the membrane while maintaining the overall aesthetic;

• Clear access for maintenance , to facilitate preventive maintenance visits (battery cleaning, connection checks, pressure checks, etc.).

Interior: comfort and discretion

Inside, the Sharp wall-mounted head unit is installed in the main living area:

• Positioned at an optimal height for even air distribution in the open area;

• Calibrated to avoid direct air currents on occupants, while ensuring effective air circulation;

• Connected to a condensation drain routed to the outside, preventing any risk of dripping into the dwelling.

Thanks to the variable speed compressor, the heat pump continuously adjusts its power:

• in air conditioning mode , to maintain a stable temperature even during heat waves;

• in heating mode , to ensure gentle and constant comfort during the winter, while reducing reliance on electric baseboard heaters.

Noise and vibration management

In dense urban environments, noise management is a major challenge. We paid particular attention to:

• the use of anti-vibration mounts under the condenser;

• controlled tightening of the bolts, in order to avoid buzzing noises;

• strategic positioning of the outdoor unit, at a reasonable distance from the resting areas of neighbors on the roof.

The result: a Sharp heat pump that operates discreetly, both for the owner and the neighborhood.

Performance and energy savings

With his Sharp wall-mounted heat pump, the Verdun customer now benefits from:

• four-season comfort : coolness in summer, warmth in winter, dehumidification in the off-season;

• reduced electricity bills , thanks to a high coefficient of performance in heating and excellent efficiency in air conditioning;

• of added real estate value , the presence of a modern and efficient heat pump being an asset for the resale or rental of the condo.

The installation complies with current electrical and mechanical standards as well as best practices recommended by manufacturers and energy efficiency programs in Quebec.
