Installation of a Midea wall-mounted air conditioner in Saint-Laurent
AirGreen installs a Midea wall-mounted air conditioner in Saint-Laurent. An HVAC project combining comfort, energy efficiency, and aesthetic discretion, expertly executed.
In summer, the outdoor unit rejects the house's heat outside.

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.
An installation project optimized for lasting comfort
At AirGreen , we recently completed the installation of a Midea wall-mounted air conditioner in a condo located in Saint-Laurent . This project perfectly illustrates our approach: offering an efficient residential air conditioning system, adapted to the specific needs of the occupants, while respecting the architectural and aesthetic constraints of the space.
Client context and needs
The owner was looking for a solution to improve comfort in the summer, without taking up floor space or increasing the energy bill. The chosen option was a Midea wall-mounted air conditioner , renowned for its reliability and energy efficiency. Its compact and modern design blends harmoniously into the apartment, while ensuring even air distribution.
Technical details of the installation
-
Equipment type : Midea wall-mounted air conditioner
-
Capacity : Suitable for an average sized room (approximately 12,000 BTU)
-
Location : condo in Saint-Laurent
-
Connection method : refrigeration piping routed directly along the wall, protected by insulation and discreet white capping
-
Condensate drainage : gravity, facilitated by the natural slope of the route
Our technicians strategically drilled holes in the load-bearing wall to reduce the length of refrigeration lines, thereby minimizing efficiency losses. The wall-mounted unit was mounted at an optimal height to ensure even air distribution without disrupting the interior design.
Challenges encountered and solutions provided
The main challenge was routing the piping in a confined space, close to a door frame. To preserve the aesthetics of the home, we opted for a discreet horizontal route, carefully covered with white capping that blends in with the wall paint.
Thanks to this approach, the installation remains sober and perfectly integrated into the decor.
Results obtained
-
Immediate comfort : the device ensures rapid and uniform cooling, even in periods of intense heat.
-
Aesthetics preserved : no visible pipes outside the wall capping.
-
Energy Saving : Midea Inverter technology allows for fine modulation, reducing power consumption and maintaining a stable temperature.
The customer now benefits from a reliable, discreet and energy-efficient air conditioning system, designed to last.

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.
