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

When this homeowner in Rosemont–La Petite-Patrie contacted us, he wanted a more comfortable heating and cooling solution than his electric baseboard heaters , but without losing floor space or sacrificing the aesthetics of his living area. We recommended the installation of aSharp wall-mounted heat pump , a perfect solution for typical homes in the neighborhood with living and dining rooms open onto a patio door.

The project: to modernize the comfort of a typical Rosemont ground floor

The main room opens directly onto a large sliding patio door leading to a glazed extension. In winter, this area was particularly cool; in summer, the sunlight made the space feel heavy and uncomfortable.

Our objectives:

• Ensuring efficient heating even in the depths of Montreal's coldest weather .

• Provide quiet air conditioning for the living room and dining area.

• Integrate the device discreetly and harmoniously into an already furnished setting (furniture, painting, wooden moldings).

• Reduce your electricity bill by replacing a significant portion of your direct electric heating with a high-efficiency heat pump .

The chosen solution: a new generation Sharp wall-mounted heat pump

We installed a Sharp residential R-32 wall-mounted heat pump , sized to cover the open-concept main floor. This type of mini-split system is ideal for:

• Townhouses and plexes in Rosemont.

• Areas where ventilation ducts are to be avoided .

• Customers who want an excellent comfort/fuel consumption ratio .

The compact, neutrally designed interior module blends seamlessly with the pale walls and wooden frames. Positioned high above the patio door, it optimizes airflow to the living room, dining room, and glazed extension.

Indoor unit positioning: performance and aesthetics

The choice of location is crucial for the performance of a wall-mounted heat pump. In this project, we have:

• Center the Sharp wall-mounted head above the patio door, at a good distance from the ceiling to allow for optimal air intake .

• Orient the supply louvers so as to direct the treated air towards the main living area , without blowing directly on the occupants.

• Respect the necessary clearances for future maintenance (cleaning of filters, inspection of coils, etc.).

Visually, the device is discreet: it fits between a decorative painting and the wooden molding of the patio door, without encroaching on the furniture or passageways.

Refrigerant line routing and condensate drainage

Behind this clean and minimalist installation lies significant technical work:

• Neat wall penetration : refrigerant lines, communication cable and drainage line pass through the wall to the outside in a single hole, protected by a sleeve and sealed to prevent any air or moisture infiltration.

• External cable tray : Outside, the pipes are grouped in a rigid, UV-resistant cable tray, matched to the color of the facade to minimize visual impact .

• Gravity drainage : the condensate pipe is laid with a constant slope to avoid any stagnation of water, an essential point for the durability of the installation and the prevention of odors.

Sharp outdoor unit: discreet and reliable in winter

The Sharp outdoor unit (not visible in the photo) was installed near the patio door, in a location:

• Sufficiently open to allow good air circulation .

• Raised on suitable supports to remain above the snow accumulation.

• Located away from traffic areas, to reduce perceived noise and facilitate snow removal.

Before commissioning, we carried out the following:

• A nitrogen pressure test to check the tightness of the refrigeration circuit.

• A thorough vacuuming process to eliminate residual moisture and air.

• A complete check of the connections, refrigerant charge and electrical protections.

The result: a system ready to face Quebec winters, with stable performance during defrost cycles.

Electrical connection and controls

To power the Sharp heat pump, our partner electricians have:

• Run a dedicated line from the electrical panel, with a circuit breaker adapted to the power of the appliance.

• Installed an outdoor circuit breaker (disconnect) near the compressor, in accordance with the Quebec Electrical Code.

The customer now benefits:

• From an intuitive wall-mounted or portable remote control for everyday use.

• With adapted operating modes: heating, air conditioning, dehumidification and ventilation.

• Fine temperature settings, time programming and modulated ventilation for customized comfort .

Everyday comfort: summer and winter in Rosemont

Thanks to this installation, the owner now benefits from:

• For efficient heating during the biting cold typical of January and February.

• Gentle and quiet air conditioning during summer heat waves.

• A substantial reduction in energy consumption , because the heat pump transfers heat instead of producing it solely by electrical resistance.

The location above the patio door also allows for better management of:

• Solar heat gain from glazed surfaces.

• The areas that were previously colder near the openings are now uniform thanks to the constant air circulation.
