In Saint-Léonard, a typical residential area in Montreal's east end with its brown brick facades, our team recently replaced an old air conditioning system with a new-generation Midea28 wall-mounted heat pump . The installation was designed for year-round comfort, but also for reliability in the depths of a Montreal winter.
Project context: replacing an old system with a 4-season solution
The owner wanted:
-
Replacing an old, noisy and inefficient condenser (visible in the foreground of the photo).
-
Benefit from efficient heating down to very low temperatures , to reduce the use of your main heating system.
-
Gain in energy efficiency and comfort, summer and winter.
-
To have a clean, compact installation that is well integrated into the brick facade.
After analyzing the house and the occupants' needs, we recommended a Midea28 wall-mounted heat pump , a flagship model from the Midea brand, designed for the Quebec climate and compatible with energy efficiency programs available in Greater Montreal.
Choosing the Midea28 wall-mounted heat pump
The Midea28 is a wall-mounted heat pump using next-generation refrigerant (R-454B), offering:
-
Stable heating down to approximately -30°C , ideal for Montreal winters.
-
Excellent air conditioning efficiency in summer, with reduced consumption.
-
Quiet operation, both indoors and outdoors.
-
A compact design, perfect for small spaces or already occupied facades.
In this project in Saint-Léonard, the Midea28 powers an indoor wall unit discreetly installed in the main living area, allowing the room to be heated and cooled quickly while improving the overall comfort of the house.
Details of the outdoor installation: safety, durability and aesthetics
In the photo, you can clearly see the Midea outdoor unit mounted on a brick wall, with the AirGreen label. Here are the key points of our installation:
1. Installation on raised wall brackets
We opted for wall mounting on reinforced metal brackets rather than a simple floor stand. This choice offers several advantages:
-
Keep the unit well above the snow level , which is essential for optimal operation in winter.
-
Protect the condenser from splashes, ice buildup and debris.
-
Facilitate maintenance and service interventions.
-
Limit the transmission of vibrations to the ground.
The supports were securely anchored in the masonry, with appropriate anchors for brick and concrete, to ensure long-term stability.
2. Refrigerant line management and aesthetics
The refrigerant pipes, communication cable, and indoor unit drain are bundled together in a brown PVC cover , positioned vertically along the brick wall. This allows:
-
To protect the pipes from weathering and UV rays.
-
To create a clean and uniform visual result, well integrated with the facade.
-
To simplify any potential future dismantling or replacement.
This attention to aesthetics is part of our signature: an AirGreen installation must be as beautiful as it is efficient.
3. Compliant and safe electrical connections
To the right of the outdoor unit, you can see the electrical box and the cable routing. We have:
-
Installed an outdoor disconnect switch that complies with the requirements of the Quebec Electrical Code.
-
Ensured cabling sized for the power of the Midea28, with dedicated circuit breaker for the main panel.
-
Checked clearances around the condenser for good air circulation and safe access for maintenance.
Working on the old equipment: transition to the new generation
The old white unit visible in the foreground was an old, less efficient air conditioner or heat pump . As part of the project, we have:
-
Safe decommissioning of the old system .
-
Recovered the old refrigerant in accordance with environmental standards.
-
Space freed up to optimize the installation of the new Midea28.
The owner now benefits from a modern Midea system offering much better energy performance, while reducing outside noise and improving interior comfort.
Winter comfort in Saint-Léonard: Midea's strength in extreme cold
A wall-mounted heat pump like the Midea28 is particularly attractive for residents of Saint-Léonard:
-
It helps to reduce the consumption of supplementary electricity or the main heating system , especially in the autumn and spring.
-
Thanks to its high-performance inverter technology, it precisely adjusts the power according to demand, avoiding frequent on/off cycles.
-
Its high seasonal yield translates into savings on the electricity bill , year after year.
Even in the middle of January, when temperatures plummet, the Midea28 continues to provide stable heating as long as the temperature remains within its operating range. It's an excellent complement to traditional heating systems, especially in a typical Montreal home with its brick walls and sometimes uneven insulation.
A discreet, clean installation, ready for years to come.
In addition to technical performance, our objective with this project in Saint-Léonard was to deliver:
-
An orderly facade, despite the presence of old equipment.
-
An easily accessible system for the recommended annual maintenance.
-
A robust installation, capable of withstanding freeze/thaw cycles and the winds of the Montreal plateau.
The result: a Midea28 wall-mounted heat pump installed neatly , elevated and perfectly suited to the needs of the house and its occupants.
