In Rosemont–La Petite-Patrie, many brick duplexes and triplexes are seeking improved comfort year-round without compromising the aesthetics of their facades. This is precisely the challenge we met for this client by installing a Midea28 wall-mounted heat pump on the exterior wall of their property, in a small, typically Montreal backyard.
In this article, we present this project by AirGreen , as well as the concrete advantages of the Midea28 for a residential building in this sector.
Context of the house in Rosemont–La Petite-Patrie
The residence is a brick duplex with a semi-above-ground basement, an exterior wooden staircase, and a small asphalt driveway. The client wanted:
-
Replacing an energy-inefficient electric heater.
-
Add air conditioning for periods of extreme heat.
-
Minimize noise as much as possible for the neighborhood and for the occupants.
-
Preserve the integrity of the brick facade and foundation.
We recommended the installation of a Midea28 wall-mounted heat pump , a high-performance system perfectly suited to Quebec winters and the sometimes scorching summers of Montreal.
Type of system installed: Midea28 wall-mounted heat pump
The chosen system is a Midea28 wall-mounted heat pump (mini-split) , operating with R-454B refrigerant and designed to:
-
Heat efficiently down to approximately −30 °C depending on the configuration;
-
To provide quiet and stable air conditioning;
-
Reduce energy consumption compared to electric baseboard heaters.
The Midea28 model is distinguished by:
-
An inverter compressor that continuously modulates its power;
-
A design geared towards extreme cold for Montreal's climate;
-
An excellent performance/price ratio, ideal for Rosemont–La Petite-Patrie homes looking for a reliable and durable system.
Installation details visible in the photo
Several technical elements stand out in this installation:
-
Outdoor condenser on wall brackets
The Midea outdoor unit is securely fixed to galvanized wall brackets .-
This helps to keep it above ground level and above the snow.
-
This limits the risk of ice, dirt or stagnant water accumulating around the base of the device.
-
Maintenance, snow removal and visual inspection become much simpler.
-
-
Installation on a brick facade and concrete foundation
The heat pump is anchored in the concrete foundation section, just below the brick wall.-
This configuration ensures excellent mechanical strength .
-
It also avoids unnecessarily drilling through the brick beyond what is needed for the refrigeration connections.
-
-
Dedicated electrical disconnect box
To the right of the outdoor unit, there is a disconnect box installed in accordance with the Electrical Code.-
It allows the heat pump to be quickly shut off for maintenance or in case of emergency.
-
This proximity meets safety requirements and simplifies the work of the technicians.
-
-
Discreet routing of refrigeration lines
The refrigeration pipes and communication cables are grouped together and protected by sheaths and covers .-
Everything is installed in such a way as to remain visually discreet.
-
The components are protected against weathering and accidental impacts.
-
-
Managing limited backyard space
The unit is positioned so that:-
Maintain sufficient clearance from the back door and wooden steps;
-
Avoid blowing directly towards the basement windows;
-
Do not obstruct traffic in the small asphalt alley.
-
This type of configuration is very representative of the realities of Rosemont–La Petite-Patrie, where every centimeter of backyard counts.
Four-season comfort for the customer
Thanks to this Midea28 wall-mounted heat pump , the customer now benefits from:
-
In summer
-
Efficient and quiet air conditioning in the rooms served by the indoor wall-mounted unit(s).
-
Precise temperature control even during Montreal heat waves.
-
-
In winter
-
From efficient heating even in very low outside temperatures.
-
A significant reduction in reliance on electric baseboard heaters.
-
More uniform comfort, without cold spots near the windows.
-
-
per year
-
Energy savings compared to traditional 100% electric heating.
-
Improved control of humidity and indoor air quality through heat pump modulation.
-
Energy performance and potential savings
The Midea28 series is designed to offer:
-
A high COP (coefficient of performance) in heating, even in cold weather;
-
Superior seasonal energy efficiency compared to older systems;
-
Power modulation avoids frequent on/off cycles, thus increasing the lifespan of the components.
For a typical Rosemont–La Petite-Patrie home, installing a Midea28 heat pump can:
-
Significantly reduce the annual electricity bill;
-
Improve the perceived comfort in living spaces;
-
Increase the perceived value of the property for a possible resale.
Noise management and respect for the neighborhood
In a densely populated area like Rosemont–La Petite-Patrie , noise is a critical issue. During installation, we:
-
Choose a height and positioning that limits the propagation of sound towards neighboring windows;
-
Checked the clearances to maintain good air circulation, which reduces the compressor's effort and therefore the noise;
-
Use supports with anti-vibration pads as needed to prevent the transmission of vibrations into the structure.
Midea28 heat pumps are already known for their low noise level; combined with careful installation, this makes them an excellent choice for Montreal alleyways and backyards.
