Installation of a Tosot wall-mounted air conditioner in Côte-des-Neiges–Notre-Dame-de-Grâce
AirGreen installed a Tosot wall-mounted air conditioner in a condo in Côte-des-Neiges–Notre-Dame-de-Grâce, offering comfort, energy efficiency and impeccable finishing.

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.
A residential project transforming the comfort of a Montreal condo
At AirGreen , we understand that every HVAC installation has its own unique characteristics. Recently, our team completed the installation of a Tosot wall-mounted air conditioner in a condo located in the Côte-des-Neiges–Notre-Dame-de-Grâce area of Montreal . The main objective was to provide optimal comfort in a bright living space while respecting the technical constraints of a modern residential building.
This type of installation perfectly reflects the growing demand from residents of Montreal for compact, efficient systems adapted to the surfaces of condos and apartments.
Why choose a Tosot wall-mounted air conditioner for this project?
The choice of the Tosot wall-mounted air conditioner is based on several key factors:
-
Energy efficiency : Tosot models are generally Energy Star certified, guaranteeing reduced consumption and electricity savings.
-
Discreet design : the installed indoor unit blends harmoniously into the aesthetics of the apartment.
-
Reliable performance : designed to provide consistent cooling, even on the hottest Montreal summer days.
-
Simplified maintenance : Washable filters and easy access to components ensure long-term durability.
Details of the installation carried out by AirGreen
Our team had to overcome several technical challenges to ensure optimal results. Here are the highlights of this installation:
-
Strategic positioning : the wall unit was installed in a central space of the condo, allowing even diffusion of fresh air to the living room and hallway.
-
Wiring and refrigerant pipes : the pipes were carefully concealed using white capping to match the wall finish.
-
Drainage management : the installation was carried out with secure gravity drainage, avoiding the use of a condensate pump.
-
Compliance with electrical standards : a careful connection has been made near the electrical panel to ensure a stable and safe power supply.
Specific context of the project
This project stands out for its location: a modern condo in the Côte-des-Neiges–Notre-Dame-de-Grâce sector, a neighborhood where wall space and interior layout require precise planning. Using a Featherlite compact ladder made it easier to work in a narrow corridor without damaging the surrounding surfaces.
Additionally, the owners wanted a quick installation so they could immediately enjoy the comfort of an air conditioning system during the summer. Our team completed the project in a single day, including commissioning and performance testing.
Concrete benefits for the customer
Following this installation, owners benefit from several advantages:
-
Immediate thermal comfort throughout the living space.
-
Reduce energy costs with an efficient and modern appliance.
-
Increased value of the condo , since the addition of a wall-mounted air conditioning system increases the appeal for a possible resale.
-
Peace of mind thanks to the AirGreen guarantee and maintenance advice provided by our technicians.

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.
