Modern comfort adapted to a Montreal plex
At AirGreen , we carry out each wall-mounted heat pump installation with particular attention to the architectural context of Greater Montreal homes. In this project, we were called upon to work in a typical plex in the Rosemont–La Petite-Patrie neighborhood, where both the interior and exterior space impose specific technical constraints. The choice fell on a Midea wall-mounted heat pump from the recent range, perfectly suited to the heating and cooling needs of an urban home.
Why a Midea wall-mounted unit in this context?
Midea's new generation heat pumps, which run on R-32 or R-454B refrigerant, are renowned for their low-temperature performance, with some reaching temperatures as low as -30°C , a key requirement for Montreal. In this home, the owners were looking for:
-
Stable comfort all year round , summer and winter.
-
Reduced energy consumption thanks to inverter technology.
-
A compact device that fits discreetly above the patio door, without disturbing the interior design.
Installation Challenges and Solutions
Installing in an urban plex requires dealing with several constraints:
1. Strategic positioning
The interior header was placed directly above the sliding patio door , an optimal location allowing for even air distribution throughout the room. This choice frees up the side walls for furnishings, while avoiding dead zones in air circulation.
2. Drilling and passage of connections
The refrigerant and electrical lines have been carefully routed to the rear, passing through the bulkhead leading to the courtyard. A discreet white trunking (capping) protects the pipes and ensures a clean and durable finish.
3. Condensate management
The drainage was carried out by gravity drain , made possible by the proximity of the patio door leading to the rear terrace. This avoids the addition of a condensate pump, thus reducing future maintenance and the risk of breakdown.
4. Climatic constraints
Montreal's climate requires protection against frost and snow accumulation. The outdoor condenser (not visible in the photo) was installed on a raised, unobstructed base, ensuring optimal air circulation and efficient drainage of defrost water.
Benefits for occupants
Thanks to this installation, residents now benefit from:
-
Efficient heating even during the bitter cold of January.
-
Pleasantly cool in summer , despite the accommodation's south-facing orientation.
-
A reduction in energy bills , compared to traditional electric heating.
-
A system eligible for provincial and federal subsidies , particularly under programs targeting high-efficiency Energy Star appliances.
AirGreen Expertise in Rosemont
This project perfectly illustrates our ability to adapt each installation to the realities of Montreal's built environment. Brick plexes in Rosemont–La Petite-Patrie often have restricted access and architectural features (narrow balconies, spiral exterior staircases, enclosed courtyards). Our technicians, accustomed to this type of configuration, carefully plan each step to reduce delays and minimize the impact on the occupants' daily lives.
Practical advice for plex owners
-
Choose models certified for extreme cold (down to -25°C or -30°C).
-
Check the possible routes for the drain : gravity preferably, otherwise integrated pump.
-
Ensure the correct outdoor installation height to avoid snow-related problems.
-
Consider available grants that can ease the cost of acquisition.
Conclusion
With this Midea wall-mounted heat pump installation in Rosemont , AirGreen once again demonstrates its expertise in integrating high-performance, discreet, and sustainable HVAC systems. For each project, we adapt our approach so that our clients enjoy the best of modern comfort, while respecting Montreal's architecture and climate.
