Installation of a Sharp wall-mounted heat pump in Villeray–Saint-Michel–Parc-Extension

In this project in Villeray–Saint-Michel–Parc-Extension , our AirGreen team was called in to transform a room that was too hot in the summer and difficult to heat in the winter into a comfortable space year-round. The challenge: to integrate a high-performance heating and cooling solution without compromising the aesthetics of the apartment, with its cream walls and decorative ceiling moldings.

We recommended the installation of aSharp wall-mounted heat pump , from the Sharp THU 12,000 BTU range, specifically designed for small and medium-sized residential spaces in Greater Montreal.

A typical setting for Villeray apartments

The accommodation is located in a typical residential building in the neighborhood:

  • relatively high ceilings with moldings ;

  • uniform walls, freshly repainted;

  • medium-sized rooms, used as a master bedroom or office ;

  • adequate insulation, but subject to temperature variations in the Montreal climate.

Before our intervention, the client used an old electric space heater in winter and a fan in summer. Result:

  • sensations of cold near the walls in January-February;

  • difficult nights and heavy air during heat waves;

  • High electricity consumption for insufficient comfort.

The client wanted a reliable, quiet, energy-efficient solution capable of ensuring stable comfort in all seasons, without cluttering the room or damaging existing finishes.

The choice of the Sharp solution

After analyzing the needs and configuration, we recommended:

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

  • Brand: Sharp

  • Installed model: Sharp THU 12,000 BTU, R-32 refrigerant

  • Main functions: high-efficiency heating, air conditioning, dehumidification, ventilation

This Sharp model offers several advantages for an apartment in Villeray–Saint-Michel–Parc-Extension:

  • High energy efficiency , ideal for reducing Hydro-Québec bills;

  • Reliable performance in cold weather , perfectly suited to Montreal winters;

  • Very low noise level , essential for a bedroom or home office space;

  • Compact and sleek design, which harmonizes with a light wall and ceiling moldings.

Indoor integration: a discreet and efficient wall-mounted heat pump

The photo shows the Sharp wall unit installed high up, just below the ceiling molding. This precise positioning serves several purposes:

  1. Optimal air distribution
    Installed in the upper part, the heat pump allows hot air to descend naturally in winter and fresh air to be distributed evenly in summer.

  2. Respect for aesthetics

    • The unit follows the line of the ceiling and remains visually discreet.

    • The white color blends perfectly with the cream walls, avoiding the “added block” effect.

  3. Functionality and maintenance

    • Access to the unit for filter cleaning remains simple.

    • The indicator lights, visible on the right side of the machine, allow you to check at a glance the current mode (heating, air conditioning, etc.).

Beneath the unit, there is a finishing box that houses the wiring and/or condensate pump. This design allows for:

  • protect the ducts;

  • maintain a clean and professional appearance;

  • Avoid exposed cables or pipes, which are often considered unsightly in a residential environment.

Technical challenges of installation in an existing dwelling

Installing a wall-mounted heat pump in an already occupied apartment requires careful attention. On this project in Villeray–Saint-Michel–Parc-Extension, we notably managed:

  1. Structural constraints

    • Determine a solid fixing point to support the weight of the Sharp unit;

    • Take into account the presence of moldings to avoid damaging them.

  2. The routing of the refrigerant lines

    • Minimize pipe length to preserve efficiency;

    • Design a discreet passage to the outside, combined with a clean cover.

  3. Condensate management

    • Implementation of adequate drainage for water produced in air conditioning mode;

    • Installation of a small box under the unit for the condensate pump when the natural slope is insufficient, ensuring reliable operation without risk of runoff on the wall.

  4. The cleanliness of the construction site

    • Protection of nearby surfaces;

    • Complete cleaning before the team's departure.

Implementation steps by AirGreen

Here's how the installation of this Sharp wall-mounted heat pump went:

  1. Evaluation visit

    • Analysis of the room (volume, exposure, insulation).

    • Checking the electrical panel and the potential location of the outdoor condenser.

  2. Planning and preparation

    • Choosing the optimal wall for the indoor unit, based on air circulation and structural constraints.

    • Preparation of equipment, supports and protective gear for the worksite.

  3. Fixing the Sharp indoor unit

    • Mounting the mounting plate on a solid support.

    • Precise alignment under the molding for a flawless visual finish.

  4. Passing of connections and external installation

    • Controlled drilling of the wall, respecting standards and limiting vibrations.

    • Installation of refrigeration pipes, wiring and condensate drain.

    • The Sharp condenser is installed outside, in a clear and easily accessible location for maintenance.

  5. Electrical connection and commissioning

    • Connection to the dedicated circuit according to the Quebec Electrical Code.

    • Vacuum sealing, leak testing and verification of the charge with R-32 refrigerant.

    • Programming of modes, ventilation and temperature settings.

  6. Explanation to the customer

    • Operation of the remote control and the main modes (Auto, Heat, Cool, Dry).

    • Recommendations for use in winter (optimal temperatures, defrosting management).

    • Maintenance advice: cleaning of filters, clearance around the condenser, periodic inspection.

Results: Four-season comfort in a Villeray apartment

Since the installation of the Sharp THU wall-mounted heat pump , the customer has benefited from:

  • Gentle and even heat during extreme cold, without localized overheating;

  • Quiet air conditioning during heat waves;

  • Improved air quality , thanks to integrated filtration;

  • A significant reduction in energy consumption , all with a discreet system that blends perfectly into the decor.

The unit is barely audible at low speed, making it an ideal solution for a bedroom or home office, where silence and comfort are essential.
