Mounted level on a wall plate, high enough for the air to reach the whole room, with enough space around it to slide the filters out easily.
The refrigerant lines, the communication cable and the drain go through the wall in a single opening, sealed against water, cold air and insects.
Two insulated copper pipes connect the two units. Outside, a line cover can protect them from sun, knocks and weather.
A shut-off switch near the outdoor unit isolates it safely for service. It must stay accessible at all times.
The compressor and the fan. In heating mode it captures heat from the outdoor air, even in winter, and moves it inside.
On the ground or on the wall, it keeps the unit above accumulated snow. The unit stays clear and defrost water can drain away.
The fan needs to blow freely. Storage, a fence or a wall too close, and efficiency drops while noise goes up.
In this residential project in Rosemont–La Petite-Patrie , our AirGreen team installed aMidea wall-mounted heat pump , a perfect choice for Montreal's plexes and typical urban brick homes. This type of configuration requires careful attention to location, exterior support, and noise management—elements we systematically incorporate into our approach.
A sensible choice for Montreal's climate: Midea wall-mounted heat pump
The installed unit is a Midea wall-mounted heat pump , a mini-split system known for its excellent performance/energy efficiency ratio. In this specific case, the chosen model is a Midea28 , a new generation wall-mounted heat pump designed to withstand Quebec winters, with reliable heating capacity down to -30°C .
The Midea28 is particularly appreciated for:
-
its advanced inverter technology,
-
its silent operation,
-
its stable performance even in extreme cold
-
its compatibility with current energy requirements.
Context of installation in Rosemont–La Petite-Patrie
The Rosemont–La Petite-Patrie neighbourhood has well-known characteristics: brick buildings, exterior steel staircases, narrow backyards, and close proximity between buildings. All these elements directly influence how a heat pump should be installed.
Visible and relevant installation details
Regarding this installation:
-
The outdoor unit is raised on a solid structure , preventing snow accumulation and ground moisture.
-
The positioning ensures good air circulation while respecting the required clearances.
-
The installation is located near the exterior staircase, optimizing space without compromising aesthetics.
-
Vibrations are minimized thanks to a stable base, a crucial point in a dense urban environment.
This type of raised support is essential in Montreal: it extends the life of the heat pump and ensures optimal operation even during freeze/thaw cycles.
Why a Midea wall-mounted heat pump is ideal for this type of residence
For a home in Rosemont–La Petite-Patrie, a Midea wall-mounted heat pump represents an excellent compromise between comfort, performance and discretion.
Concrete benefits for occupants

And at your place?
Two quick checks with real numbers: what heat costs, and what your current heaters add up to in BTU/h.
Conversion: 1 W = 3.412 BTU/h. An indication, not a load calculation: baseboards and furnaces are often stronger than the real need, and they can stay as backup. AirGreen confirms the capacity on site.
