When Architectural Complexity Meets AirGreen’s Technical Expertise
Installing a wall-mounted air conditioner on a sloped ceiling in Longueuil might seem like an impossible mission for some HVAC contractors. But at AirGreen, we turn technical challenges into opportunities to showcase our know-how. This project, located in a contemporary-style bungalow in the Fatima neighborhood of Longueuil, is a perfect example of our ability to deliver tailored solutions—even in situations others wouldn’t dare attempt.
Project Background: An Unusual Request, A Very Real Need
Our client wanted to install a wall-mounted air conditioner in an open-concept living space on the top floor of their home. The only catch: the only wall available for the indoor unit followed a cathedral-style ceiling sloped at a 45-degree angle.
The request was clear: “I want the comfort of a wall-mounted heat pump, even if other companies told me it wasn’t possible.”
Initial Analysis and On-Site Technical Evaluation
During our first technical visit, our team identified several major constraints:
-
Incline too steep for standard wall-mounted installation.
-
No vertical load-bearing wall in the targeted area.
-
Limited outdoor access, due to an integrated balcony at the same level as the ceiling.
-
Refrigerant line length needed optimization to maintain the system’s energy efficiency.
Faced with these challenges, our installation team proposed an innovative solution: designing a custom aluminum-reinforced wall bracket capable of bearing the weight of the unit while complying with the airflow direction and ceiling angles.
The Technical Solution: Custom Engineering and Precise Adjustments
System Installed:
-
Brand: Gree
-
Model: Gree Lomo 12000 BTU Inverter
-
Type: High-efficiency wall-mounted air conditioner
-
Refrigerant: R-32
-
Energy rating: A++
-
Eligible for Hydro-Québec’s LogisVert program
Installation Steps:
-
Custom-designed triangular anchor bracket made of galvanized steel, mounted to both the ceiling and the lateral faux-wall.
-
Reinforcement of existing wood structure with additional metal brackets to ensure long-term stability.
-
Precision-drilled wall opening, with conduit routing aligned to the ceiling’s slope.
-
Outdoor condenser unit installed on anti-vibration platform, strategically positioned on the north side of the house, shaded from direct sunlight.
-
Comprehensive check of system sealing, refrigerant pressure, and airflow performance.
On-Site Challenges
We encountered severe weather conditions—rain and strong winds—during the outdoor portion of the installation. Thanks to our thorough planning, we protected the equipment using industrial tarps and completed the job in phases, never compromising quality.
We also had to adjust the slope of the condensate drainage line to avoid backflow into the interior—a common mistake in poorly executed similar projects.
Final Result: Optimal Comfort with No Aesthetic Compromise
The system works perfectly and blends seamlessly into the living space, without affecting the architectural design. Thanks to the angled bracket installation, the indoor unit is stable, quiet, and effectively distributes cool air throughout the entire room—even during heatwaves.
The client expressed high satisfaction, stating our work “exceeded all expectations” and that “AirGreen’s customer service truly lives up to its reputation.”
