A Vertical HVAC Installation at the Top of Downtown Montréal
Some HVAC installations are not just about technical skill, but also about high-altitude work. This was precisely the case with a project our team at AirGreen took on atop a luxury residential skyscraper in downtown Montréal. The installation of a wall-mounted air conditioner at height, in a wind-exposed environment, inaccessible by standard equipment, and subject to significant structural constraints, highlighted our expertise, ingenuity, and meticulousness in the most extreme situations.
A Luxury Apartment... on the 33rd Floor
The client, owner of a high-end condo on the 33rd floor of a high-rise building, was experiencing overwhelming heat as the full-height glass windows allowed a substantial thermal load. The existing unit was no longer sufficient to adequately cool the space. The solution: replace the existing system with a LG Art Cool Mirror 12,000 BTU wall-mounted air conditioner, known for its sleek design and high performance in urban environments.
Technical Features of the LG Art Cool Mirror Wall-Mounted Air Conditioner
This model was chosen for its rapid cooling capacity in challenging environments while being discreet and aesthetically pleasing. Here are its key advantages:
-
12,000 BTU, for a space of 400 to 550 sq. ft.
-
Ultra-modern black mirror design, ideal for high-end interiors
-
Dual Inverter technology reducing vibrations and noise
-
Energy Class A+++, perfect for energy-conscious clients
-
Eligible for Hydro-Québec’s LogisVert program depending on the building’s configuration
Key Steps in a High-Altitude HVAC Installation
1. Limited Roof Access and Coordination with Building Management
Accessing the exterior façade of the condo required full coordination with the condo board, building managers, and approval to enter via a suspended platform. The equipment was transported via the service elevator, then manually hoisted to the installation point.
2. Site Safety and Working at Height
Our technicians, all certified for working at height, operated with harnesses, lifelines, and equipment compliant with CNESST standards. Winds of over 25 km/h delayed the operation by half a day, demonstrating the importance of operational flexibility in unpredictable weather conditions.
3. Drilling Through Reinforced Concrete Walls
The interior unit was installed on a shared wall, while the outdoor unit required a reinforced anchoring on a concrete wall, overlooking the void. Expansion bolts for reinforced concrete, combined with vibration dampers, ensured a stable fix despite the altitude constraints.
Result: Optimal Comfort and Aesthetic Integration in an Extreme Setting
Thanks to this installation, the client now enjoys consistent, quiet cooling adapted to the vertical layout of their apartment. The LG Art Cool Mirror unit, in addition to its proven performance, adds a sophisticated decorative touch to the living space.
Client Testimonial: “AirGreen Did What Others Refused to Attempt”
The owner shared that several companies had declined the installation due to logistical and structural risks. At AirGreen, we carefully studied each constraint, developed a secure intervention plan, and, most importantly, met the promised deadlines despite unforeseen weather delays.
