In Rosemont–La Petite-Patrie, brick houses, back patios, and exterior staircases are part of the scenery… as are the HVAC challenges that come with our seasons. At AirGreen , we recently installed a Midea heat pump (outdoor unit) in a typical backyard in the area: limited space, traffic near a staircase, and the need for a reliable unit for both cooling and heating.
The client's objective was simple: to achieve stable comfort , reduce reliance on supplemental heating, and secure a clean, discreet installation adapted to Montreal winters.
The type of system: an efficient and compact residential heat pump
From the photo, it's clearly a residential heat pump with a front-mounted outdoor unit , installed on a raised base . This format is very common for wall-mounted heat pumps (mini-splits) : it offers excellent efficiency, precise zone control, and quiet operation when properly positioned.
This is exactly the kind of device that is suitable for homes in Rosemont: single-family homes, plexes, two-story condos, where an efficient solution is needed without redoing the entire distribution of conduits.
Brand: Midea (as requested)
The brand to use here is Midea , and that's very good news: Midea has carved out a solid place in residential heating thanks to high-performance, modern appliances that are well-suited to the Quebec climate when you choose the right range.
Selected model: Midea28 (consistent with the installation)
The model is not directly visible in the photo, but the configuration and positioning correspond very well to a new generation Midea wall-mounted heat pump installation, and at AirGreen we often favour a range of the Midea28 type, known for its heating capacity in winter conditions and its stability in defrost mode.
Without overloading with figures, remember this: what matters is not just the BTU “on paper”, but the actual heating capacity when it is cold , and the quality of the installation (clearances, drainage, support, vibrations, etc.).
Observable installation details: what was done (and why)
In the photo, several good technical choices stand out — and they have a direct impact on long-term reliability.
1) Elevated support: essential in Montreal
The outdoor unit is installed on a raised metal stand . In winter, this is a major consideration:
-
This prevents snow from accumulating and blocking the interchange.
-
This reduces the risk of ice buildup at the bottom of the device.
-
The defrosting process is improved (the water can drain properly)
-
We extend the lifespan by limiting corrosion and exposure to puddles.
In a neighborhood like Rosemont, where backyards can be damp, shaded, or cluttered, this elevation is often the difference between a machine that lasts... and a machine that suffers.
2) Position near the staircase: managing clearances and airflow
The unit is located near an exterior staircase and platform. When space is limited, our job is to respect:
-
minimum clearances for air intake and exhaust
-
traffic flow around the unit (avoid the “cage” effect)
-
reducing turbulence that can impair efficiency and increase noise
Here, the location is intelligent: the unit is oriented so as to breathe properly despite the context, while remaining accessible for maintenance.
3) Vibration and noise management
A properly installed heat pump is audible (or rather… almost inaudible). With this type of installation, we always plan for:
-
anti-vibration pads
-
Stable, twist-free attachment
-
Level check (important for defrost drainage)
Result: less resonance in the structure, and more comfort for the occupants — especially when the unit is working in heating mode in cold weather.
4) Protection against leaves and debris: an underestimated issue
You can clearly see leaves on the ground around the installation (typical in autumn). It seems harmless… until it isn't.
Our advice (and the advice we always follow):
-
keep a clear perimeter around the unit
-
prevent leaves from accumulating near the exchanger
-
Plan for periodic cleaning, especially before winter and in spring.
A heat pump performs better when it breathes better. Simple, but crucial.
Why this installation is particularly well-suited to Rosemont–La Petite-Patrie
The houses in this area often have one thing in common: they want comfort, but without compromising on aesthetics and space .
A well-integrated Midea wall-mounted heat pump allows for:
-
to effectively air-condition during heat waves
-
to heat a good part of the cold season
-
to reduce energy bills by decreasing the use of direct electric heating
-
to improve comfort room by room, without major renovations
And most importantly: with an elevated, well-cleared and well-stabilized installation, we increase reliability in real-world conditions — those we experience here, not those of a laboratory.
Our AirGreen approach: clean, sustainable, and performance-oriented installation
When we install a heat pump, our priority isn't just to "make it work." We aim to:
-
the actual return (not just the advertised return)
-
longevity (support, drainage, clearances, protection)
-
everyday comfort (noise, diffusion, stability)
-
future maintenance (access, cleaning, inspection)
This is exactly what we look for in a typical Montreal backyard: a solution that respects the space… and that survives the winter without surprises.
Recommended maintenance: the key to keeping Midea performance at its best
Even an excellent heat pump loses efficiency if it is not maintained. For this type of installation, we recommend:
-
seasonal inspection and light cleaning (debris, leaves, clearings)
-
Periodic more thorough cleaning (depending on use and environment)
-
Check the defrost drainage system before the onset of severe cold.
A clean device = better heat transfer = less effort = less wear.
