A complex HVAC operation executed with precision and safety on a high-rise residential tower on the North Shore
Installing a wall-mounted air conditioner at height is already a delicate task. Doing it over 50 meters off the ground, on the façade of a residential building in the heart of Laval, takes technical and logistical expertise to an entirely new level. That’s exactly what our AirGreen team accomplished by carrying out an HVAC installation with millimeter precision, meeting the highest standards of safety, performance, and energy efficiency.
The Context: A High-Rise Condo Dealing With Excessive Heat
The project involved a condo located on the 14th floor of a modern residential tower in the Laval-des-Rapides neighborhood. The owner, who had recently moved in, was experiencing significant temperature spikes during the summer, especially in the sun-facing glassed-in living room.
The building did not have a centralized air conditioning system, and installing an individual wall-mounted air conditioner was the only viable solution. However, the building’s height came with strict constraints around access, exterior anchoring, and working safely at elevation.
AirGreen’s Assessment: Designing a Safe and Custom-Tailored Solution
Our HVAC experts conducted a thorough technical study:
-
Area to be cooled: 620 sq. ft., including the living room, kitchen, and main bedroom
-
Recently insulated, but significant solar gain through the windows
-
Limited access to the outer façade from inside the unit
-
Reinforced concrete structure, ideal for anchoring
-
Strict condo board rules regarding exterior façade aesthetics
Taking all these into account, we recommended installing a 12,000 BTU Fujitsu Inverter wall-mounted air conditioner, known for being compact, quiet, and especially suited to high-rise units with sun exposure.
The HVAC Installation Steps 50 Meters Up
The job unfolded in three major phases, coordinated with the condo board and a vertical access specialist:
-
Interior preparation: wall unit installation, diamond core drilling into concrete, reinforcing the internal structure
-
Outdoor unit mounting: suspended motorized platform anchored to the roof, custom galvanized steel wall bracket
-
Safe electrical connection: independent circuit protected by double breaker, wiring routed through fire-resistant conduit
Each step was completed in full compliance with RBQ standards and working-at-heights safety protocols, under the supervision of a structural engineer.
Result: Performance, Silence, and Seamless Integration
Right after commissioning, the owner noticed a rapid temperature drop, even on the hottest days. Key benefits included:
-
Ultra-quiet operation, perfect for remote work
-
Preserved building aesthetics, with no visible wiring on the façade
-
Optimized energy usage thanks to Inverter technology
-
Zero vibration, even at that height
The condo board approved the installation as fully compliant, paving the way for similar requests from other residents.
Challenges Faced and Solutions Delivered
A project this complex naturally involved a number of challenges, which our team overcame with rigor:
-
Wind conditions at 50 meters: work scheduled during an optimal weather window, with an added lifeline
-
Lifting the outdoor unit to height: done with a lightweight telescopic crane, coordinated with city permits
-
Long-lasting anchoring without compromising building waterproofing: used high-density polyurethane sealant and anti-infiltration plate
-
Noise and vibration testing: post-installation validation with a sound meter and thermal camera
