A technical installation by AirGreen: performance, discretion and security in a closed environment
At AirGreen , we face unique challenges every day. This time, our team was tasked with installing a Sharp ZU1 heat pump in an underground parking lot of a residential building in Ville Saint-Laurent , an area known for its modern condominiums and demanding technical infrastructure. The goal: to ensure efficient heating and cooling while optimizing space and respecting the structural constraints of reinforced concrete.
A special installation environment
Installing an HVAC system in an underground garage requires specialized expertise. Space is limited, air circulation is limited, and vibration and noise management is essential to avoid any disturbance to residents. Our team therefore opted for a suspended configuration on galvanized rails, securely attached to the concrete slab.
Adjustable metal brackets ensure maximum stability and allow for easy maintenance of the Sharp condenser, while freeing up floor space for vehicles. This installation option also provides better protection against water or salt spray in winter.
The Sharp ZU1 choice: power and reliability in a compact format
The Sharp ZU1 wall-mounted heat pump is one of the R-32 models, energy-efficient and efficient, capable of operating down to -25 °C . Ideal for Quebec climates, it combines:
-
Eco Inverter technology , reducing energy consumption by up to 30%.
-
Integrated Plasma Cluster system , purifying the air and eliminating fine particles.
-
Ultra-quiet operation , essential in dense residential environments.
-
Compatibility with Quebec subsidy programs , such as Hydro-Québec's LogisVert .
This compact yet robust outdoor unit is particularly suitable for condominiums where space is a precious resource.
Technical details of the installation
Our RBQ-certified technicians ensured a clean, safe, and HVAC-compliant installation. Here are the key points of the project:
-
Suspended support made of galvanized steel, mechanically anchored in concrete.
-
Refrigeration lines insulated and protected in a black sheath for increased durability.
-
Secure electrical connection with metal conduit, compliant with the Quebec Building Code.
-
Gravity drainage with slight slope to avoid the accumulation of condensate.
-
Optimized clearances to ensure adequate ventilation of the unit.
Every detail has been thought out to guarantee the safety , longevity and energy performance of the system.
Challenges encountered and solutions applied
The main challenge of this installation was the limited ceiling height and the proximity of the mechanical ducts in the parking lot. Through preliminary 3D planning , our team was able to determine the ideal location for the condenser without disrupting circulation or compromising the performance of the heat pump.
An anti-vibration mount has also been added to minimize sound transmission to the concrete—an essential precaution in buildings with rigid structures.
Result: efficiency, aesthetics and peace of mind
The end result is a clean, solid and discreet installation , harmoniously integrated into the existing infrastructure. The client now benefits from a high-performance, quiet and durable HVAC system, designed to meet their comfort needs in both summer and winter.
At AirGreen , we combine cutting-edge technology , precise engineering , and local know-how to deliver heat pump installations that exceed expectations—whether in an urban condo, single-family home, or underground garage.
