An HVAC installation project that combines comfort and discretion
At AirGreen , we recently completed a Senville LETO wall-mounted air conditioner installation in an apartment in the Rosemont–La Petite-Patrie area of Montreal. This urban neighborhood, known for its brightly lit plexes, often requires compact and quiet air conditioning solutions, perfectly suited to residential spaces where every detail counts. Our client wanted to improve their summer comfort while maintaining a discreet and elegant aesthetic in their living room.
Choosing the Senville LETO: performance and accessibility
The Senville LETO is a model renowned for its reliability, ease of use, and balanced energy efficiency . Available in various capacities, it is well suited to Montreal apartments where the average room size generally requires a power output of 9,000 to 12,000 BTUs. This choice helps maintain a stable temperature while reducing energy consumption, a crucial point for residents sensitive to electricity costs.
-
Machine type : wall-mounted air conditioner (mini-split)
-
Brand : Senville
-
Model : LETO
-
Capacity : 9,000 or 12,000 BTU (depending on the configuration chosen for the accommodation)
-
Grant eligibility : generally not applicable, as this is a wall-mounted air conditioner and not a heat pump, but its low consumption remains a financial asset.
Technical details of the installation
Since the apartment is located on the first floor of a typical Rosemont apartment complex, the installation required a direct wall penetration to connect the indoor header to the outdoor condenser. Here are the key points of the project:
-
Indoor positioning : wall unit installed at the optimal height, above the living room sofa, ensuring even air diffusion.
-
Drainage management : installation of a discreet gravity drain , avoiding the need for a condensate pump and thus reducing noise and maintenance.
-
Refrigerant connections : reduced length (less than 3 meters), minimizing efficiency losses.
-
Aesthetic finish : use of discreet white capping , harmonized with the color of the wall, for a refined visual effect.
-
External support : condenser fixed on sturdy wall brackets, on the rear facade, allowing floor space to be freed up and maintenance to be facilitated.
Challenges encountered and solutions provided
As is often the case in older buildings in Rosemont, we had to deal with thicker than average walls , requiring specialized tools for drilling. In addition, the client wanted to maintain a fully reversible and aesthetic installation, without distorting the interior design. Our technicians therefore:
-
Performed a precise drilling with a diamond core drill to penetrate the load-bearing wall.
-
Ensure the seal is sealed with suitable weatherstripping to prevent any infiltration of air or moisture.
-
Position the unit to avoid direct airflow onto the rest area while maximizing thermal comfort.
Results obtained
Upon commissioning, the customer noticed an immediate reduction in the heat accumulated in his home. The Senville LETO wall-mounted air conditioner stood out for:
-
Its quiet sound : almost inaudible operation at low speed.
-
Its rapid and even diffusion of air in the main room.
-
Its intuitive control via remote control, allowing you to easily adjust the temperature.
The client particularly appreciated the cleanliness of the installation and the care taken with the finishes, a guarantee of professionalism specific to the AirGreen team.
Why choose AirGreen for your wall-mounted air conditioner installation in Montreal?
Installing a wall-mounted air conditioner may seem simple, but each project has its own specificities:
-
Architectural constraints (wall thickness, room layout, facade orientation).
-
Drainage management (gravity vs. condensate pump).
-
Optimization of the length of refrigerant connections to maintain efficiency.
-
Aesthetics of the installation, often neglected but essential in a home.
At AirGreen, we make it a point of honor to respect these details, ensuring our customers comfort, energy efficiency and sustainability . Whether you are in Montreal, Laval, Longueuil, on the North Shore or the South Shore , we adapt each installation to your needs and your environment.
Maintenance and recommendations to extend the lifespan
A wall-mounted air conditioner like the Senville LETO requires regular maintenance to ensure its longevity:
-
Clean filters every 4 to 6 weeks during periods of intensive use.
-
Annual verification of refrigerant pressures and performance by a certified technician.
-
Drain inspection to prevent blockages and water leaks.
These best practices help maintain optimal performance while avoiding costly repairs.
Conclusion
The installation of this Senville LETO wall-mounted air conditioner in Rosemont–La Petite-Patrie perfectly illustrates our approach: adapting HVAC technology to the customer's real needs and the constraints of their home . The result: a more comfortable summer, careful installation, and guaranteed peace of mind.
