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

In this typical Rosemont–La Petite-Patrie apartment, our AirGreen team was tasked with modernizing the comfort of a courtyard-facing room. The goal: to provide reliable heating in winter and efficient air conditioning in summer, without altering the apartment's character or encroaching on the already limited space near the window.

We recommended and installed aSharp wall-mounted heat pump , model from the Sharp ZU1 12,000 BTU range, perfectly suited to the needs of this room and the rigorous climate of Montreal.

Context: a Montreal apartment with brick walls

The accommodation is located in a building typical of the area: brick exterior walls, relatively low windows, decorative ceiling moldings and limited wall space.

Before our intervention, the client relied on an inefficient heating system and a portable fan during heat waves. The result:

• Unequal temperatures between winter and summer

• Significant discomfort during hot nights

• High energy consumption for a disappointing result

The client wanted a discreet, silent and energy-efficient solution, capable of heating efficiently in very cold weather while ensuring cool and pleasant air in summer.

Solution choice: a Sharp wall-mounted heat pump

After analyzing the room, its insulation, and its exposure, we opted for:

• System type: Single-zone wall-mounted heat pump (mini-split)

• Brand: Sharp

• Model: Sharp ZU1 12,000 BTU , High-Efficiency R-32 Technology

• Use: primary heating of the room in winter, efficient air conditioning in summer

This Sharp heat pump model is distinguished by:

• Excellent energy efficiency , ideal for reducing electricity bills in Montreal

• Reliable performance in cold weather , to withstand Quebec winters

• Very quiet operation , essential in a living or working room

• A compact and sleek design that blends well into a white decor with ceiling moldings

Interior design: aesthetics and performance

The photo shows the wall unit installed high up, just below the ceiling line , above a clear wall. This position was not chosen at random:

• It allows optimal air diffusion , which circulates freely throughout the room.

• The unit remains outside the direct field of vision , which reduces the impression of clutter.

• It respects the existing moldings and the style of the room, without unnecessary visual interruption.

Nearby, a window overlooks the brick facade of the neighboring building. We chose to shorten the refrigerant lines between the indoor unit and the outdoor condenser as much as possible , in order to limit losses and maintain maximum efficiency.

The conduits were carefully concealed within a box painted the same color as the walls , resulting in a clean and harmonious visual effect. The library was protected with tarpaulins, demonstrating the importance we place on maintaining a clean worksite for our clients.

Technical challenges of the installation in Rosemont–La Petite-Patrie

Installing a wall-mounted heat pump in an existing building in downtown Montreal always requires special attention:

1. Brick structure

   • The need to precisely choose the point of entry for connections to the outside.

   • Use of appropriate tools to drill without weakening the masonry.

2. Limited space around the window

   • Obligation to avoid any conflict with the doorway, curtains or shelves.

   • Positioning calculated so that the airflow does not hit the occupant directly, but sweeps across the room.

3. Respect for the interior character

   • Preservation of moldings and architectural lines.

   • Discreet integration of the pipe finishing box.

Thanks to our expertise in residential HVAC, we were able to meet these challenges without compromising on performance or aesthetics.

Work progress by the AirGreen team

Here is how a typical intervention for this project in Rosemont–La Petite-Patrie unfolded:

1. Technical visit and sizing

   • Analysis of the room, its orientation and heat loss.

   • Checking the available space for the Sharp indoor unit and the location of the outdoor condenser.

2. Premises protection

   • Tarpaulins were placed over the library, the floor and the furniture.

   • Demarcation of the work area to limit dust.

3. Installation of the Sharp wall unit

   • Secure fixing of the mounting plate in the wall structure.

   • Precise positioning to comply with the clearances recommended by the manufacturer.

4. Routing of connections and installation of the outdoor condenser

   • Controlled drilling of the wall outwards while respecting the brickwork.

   • Installation of refrigeration pipes, condensate drain and wiring, all protected by a discreet cover .

5. Electrical connection and commissioning

   • Connection to the electrical circuit in accordance with the Quebec Building Code.

   • Vacuum sealing, leak testing and filling according to standards.

   • Configuration of operating modes (heating, air conditioning, dehumidification).

6. Handing the product to the customer and providing an explanation

   • Presentation of maintenance methods and instructions.

   • Tips for optimizing use in winter as well as summer.

Results: 4-season comfort in a Rosemont apartment

After the Sharp wall-mounted heat pump was installed, the customer now benefits from:

• Stable comfort all year round , with a consistent temperature in the room.

• Efficient heating even during the extreme cold of January and February.

• Silent air conditioning during heat waves, without a noisy fan or a window obstructed by a portable air conditioner.

• A significant reduction in energy bills , thanks to the high efficiency of the heat pump and the R-32 refrigerant.

Visually, the unit blends seamlessly into the décor: white, compact, and aligned with the ceiling moldings. The finishing box around the window and pipes melts into the walls, resulting in a clean, neat, and professional installation.
