Gree wall-mounted heat pump installation in Plateau-Mont-Royal

In the Plateau-Mont-Royal neighbourhood, the narrow streets and typical brick buildings often present particular challenges for the installation of heating and air conditioning systems. On this project, our team completed the installation of a Gree wall-mounted heat pump for a residential unit, optimizing performance, aesthetics, and ease of maintenance.

The setting: a brick building with access via the alley.

The building is a typical Plateau duplex, with:

  • Brick facade and section of plastered wall at basement level

  • Exterior metal staircase providing access to the upper floors

  • A limited space in the backyard and alley, shared with the other dwellings

The owner wanted:

  • Replacing your aging air conditioning system with a 4-season solution

  • Benefit from improved energy efficiency in heating to reduce your electricity bill

  • Keep the alleyway clear , with no equipment on the ground.

  • Having a clean and durable installation, compliant with current standards

Equipment choice: Gree high-efficiency wall-mounted heat pump

We recommended the installation of a Gree wall-mounted heat pump , high-efficiency residential range, of approximately 12,000 BTU , perfectly suited to the size of the dwelling and its open-plan layout.

This type of system offers:

  • Efficient air conditioning during summer heat waves

  • Efficient heating across a wide temperature range, ideal for most of a Montreal winter

  • Quiet operation , both for the occupants and the neighborhood.

  • Reduced energy consumption , particularly advantageous in the face of rising electricity costs

Inside, a discreet Gree wall head was installed in the main living area to ensure even air circulation throughout the dwelling.

Gree Outdoor Condenser Installation Details

The photo shows the Gree outdoor condenser securely fixed to the building wall. Here are the main technical components of the installation:

  1. aluminum wall bracket

    • Installation on a sturdy wall bracket , fixed in the plastered section of the wall, under the brick.

    • Sufficient height above the ground for:

      • Avoid snow accumulation

      • Facilitate snow removal around the unit

      • Reduce the risk of dust or debris being thrown up

  2. Managing the space under the stairs

    • Optimized positioning to comply with the clearances recommended by Gree for condenser ventilation.

    • The unit is positioned so as not to obstruct the metal staircase or the passage in the alley.

  3. Refrigeration connections and insulation

    • The insulated refrigeration pipes (black sheath visible in the photo) are carefully routed to the rear of the unit.

    • Enhanced insulation limits heat loss in winter and protects the lines from the elements.

    • The route has been designed to remain as discreet as possible , while still being easily accessible for maintenance.

  4. Condensate drainage

    • The white drain pipe visible at the bottom allows for the evacuation of water generated by the heat pump in air conditioning mode.

    • Its slope and outlet are configured to avoid water accumulation near the foundation.

  5. Power supply and safety

    • An outdoor disconnect box has been installed in the immediate vicinity of the unit, as required by the electrical code.

    • The cabling is protected and follows a clean path along the wall, minimizing visual impact while ensuring maximum safety for technicians during future interventions.

  6. Noise and vibration reduction

    • Anti-vibration pads are used between the condenser and the wall bracket to reduce noise transmission to the building structure.

    • The result: discreet operation, both inside the home and for the neighbors.

Performance and reliability in Montreal's climate

Gree wall-mounted heat pumps are designed to operate efficiently in harsh climatic conditions like those of Greater Montreal. For this project in Plateau-Mont-Royal, the client now benefits from:

  • A more economical heating option than electric baseboard heaters for most of the cold season

  • Rapid air conditioning during periods of intense heat, even in a south-facing apartment

  • Offering consistent comfort thanks to power modulation and different modes (Night, Eco, temperature maintenance)

  • Increased reliability , supported by installation in accordance with manufacturer's recommendations and local standards

Tangible benefits for the owner

Since the Gree wall-mounted heat pump was installed, the homeowner has been enjoying:

  • Better temperature control throughout his home

  • Four-season comfort , without needing multiple devices

  • An anticipated reduction in his electricity bill , especially in winter

  • Adding value to the building , a significant asset on the rental or resale market

Furthermore, the installation at height and on a wall support completely frees up the floor: no concrete block or bulky base in the alley.

AirGreen: Your Gree heat pump specialist in Greater Montreal

At AirGreen, we are very familiar with the realities of buildings in Plateau-Mont-Royal , Rosemont, the Southwest, Laval, and the South Shore. Each project is studied accordingly.

  • From the building's configuration

  • Access constraints (stairs, alleyways, narrow courtyards)

  • The actual heating and air conditioning needs of the occupants

  • Requirements from energy efficiency programs and manufacturers

We support our customers from choosing the right Gree heat pump to installation and commissioning, then to after-sales service and seasonal maintenance.
