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

An HVAC installation project in the heart of an urban condo

At AirGreen , we are regularly called upon for projects in dense urban environments, where architectural and technical constraints require a precise approach. This Gree wall-mounted heat pump installation in a condo in Rosemont–La Petite-Patrie, Montreal, perfectly illustrates our expertise in HVAC solutions adapted to multi-unit buildings .

The outdoor unit is installed on a stable metal structure directly against a brick wall, typical of Montreal buildings. The location—a narrow balcony overlooking the rear of a building—required careful organization of the available space, while respecting safety and air circulation standards.


Why choosing a Gree heat pump is a good idea in Montreal

The Gree brand is increasingly establishing itself as a key player in the Quebec wall-mounted heat pump market. Thanks to their high energy performance, Gree units offer excellent performance even in periods of intense cold, down to -25°C for some models. This means:

  • Comfort in all seasons : efficient heating in winter, efficient air conditioning in summer.

  • Energy savings through competitive SEER and HSPF ratings.

  • Compatibility with grant programs such as LogisVert or the Federal Energy Renovation Program.

For this project, the client wanted to replace an energy-intensive portable air conditioner with a permanent, reliable, and quiet system. The Gree wall-mounted heat pump emerged as the optimal solution, both in terms of performance and value for money.


The technical challenges of the installation

Managing restricted space

The balcony had limited depth, so we opted for a raised galvanized steel support , allowing the floor slab to be clear and ensuring sufficient clearance for ventilation of the unit. This configuration also facilitates future maintenance.

Drilling and crossing the brick wall

The solid brick facade requires rigorous engineering. Precise core drilling allowed the refrigeration and electrical conduits to be routed to the indoor unit, ensuring a perfect seal. Discreet white capping was installed inside for an aesthetically pleasing appearance, and professional sealing protected the exterior from water infiltration.

Condensate management

Given the height, we opted for natural gravity drainage , avoiding the addition of a condensate pump which would have generated additional costs and maintenance.


A project carried out according to the rules of the art

The work was carried out in a single day by a team of two certified technicians. Each step, from drilling cores into the masonry to the electrical connection , was carried out in accordance with RBQ and Canadian Electrical Code standards.

Before commissioning, we carried out:

  • A complete vacuum to eliminate all moisture in the refrigeration ducts.

  • A pressure test to ensure the circuit is watertight.

  • Calibration of the indoor unit to optimize the thermal comfort of the condo.

The customer immediately noticed the difference: silence, consistent freshness, and above all the prospect of reduced electricity bills in the medium term.


Concrete benefits for the customer

  • Four-season comfort : heating and air conditioning integrated into a single unit.

  • Available grants : The installed Gree heat pump is eligible for provincial and federal programs.

  • Respected aesthetics : careful installation, discreet capping, robust but compact support.

  • Simplified maintenance : direct access to the outdoor unit on the balcony.


Conclusion: an exemplary HVAC installation in Rosemont

This project illustrates how a Gree wall-mounted heat pump installation in Rosemont–La Petite-Patrie can transform the comfort of an urban condo. Despite space and masonry constraints, the AirGreen team was able to deliver an efficient, sustainable solution adapted to Montreal's climate.
