A demanding HVAC installation project in a tight space in downtown Montreal
At AirGreen , we were recently called upon to work in a condo in the Ville-Marie district of Montreal , where the client wanted to improve the comfort of their space while maintaining a discreet and functional design . The environment, a narrow corridor with little ceiling clearance, presented a technical challenge typical of modern urban housing.
Analysis of needs and choice of equipment
The client was looking for an energy-efficient , quiet solution that fit the layout of their condo. After a detailed assessment, our team recommended installing a Midea 12,000 BTU wall-mounted air conditioner , known for:
-
Its compactness , ideal for restricted spaces;
-
Its quiet operation , perfect for apartments;
-
Its high energy efficiency (SEER rate greater than 20);
-
Its minimalist design blends harmoniously into any interior decor.
Preparation of the site
Before installation, we took care to evaluate:
-
The optimal route for the passage of electrical cables and refrigerant pipes;
-
The strength of the load-bearing wall above the door;
-
The position of the condensate drain to avoid any water stagnation.
The indoor unit was precisely mounted above the door, a position requiring careful planning to ensure both optimum airflow efficiency and structural safety .
Installation of the molding and aesthetic integration
In this type of installation, visual appeal is as important as performance. We therefore used a discreet white molding to conceal the ducts running along the ceiling. This choice made it possible to:
-
Effectively protect copper cables and pipes;
-
Maintain a clean and professional appearance;
-
Facilitate any subsequent maintenance.
The custom-fit molding follows the angles of the wall and ceiling for near-invisible integration—an often overlooked, but essential aesthetic detail in small residential spaces.
Connection to the external compressor
Outside, our team positioned the Midea condenser on an anti-vibration wall mount. This configuration reduces operating noise transmitted to the structure and ensures proper evacuation of hot air . We also have:
-
Tested the refrigeration circuit pressure with nitrogen to detect any potential leaks;
-
Performed a complete vacuum of the system before commissioning;
-
Checked the drain flow and communication between the two units.
Commissioning and performance testing
Once the installation was complete, we launched the full testing phase :
-
Blowing temperature control;
-
Checking automatic defrosting ;
-
Measurement of the sound level in operation;
-
Remote control adjustment and Wi-Fi synchronization for smart control via mobile app.
The results confirmed optimal performance : the air conditioner reached the set temperature within minutes, maintaining constant and uniform comfort in the hallway and adjacent rooms.
Special challenge: low ceiling and limited clearance
This project perfectly illustrates our expertise in adapting HVAC installations in constrained spaces . The low ceiling and narrow angles made access difficult, but thanks to careful planning and specialized tools (laser level, mounting template, thermoformed trunking), we were able to:
-
Avoid excessive drilling;
-
Ensure gravity drainage without backflow;
-
Ensure stable airflow in a limited circulation space.
Final result: comfort, efficiency and preserved design
A few hours after installation, the customer immediately felt the difference:
-
A pleasant and uniform temperature throughout the accommodation;
-
An almost imperceptible noise , even in turbo mode;
-
Careful aesthetic integration , without visible wiring or visual impact.
This installation demonstrates that even in condos in downtown Montreal, it is possible to benefit from a high-performance, discreet and durable air conditioning system , provided that it is designed and installed by certified HVAC professionals .
