A sheltered installation optimized for performance in all seasons
At AirGreen , we recently installed a Gree Flexx R32 central heat pump in a residential building in the Chomedey sector of Laval . This project was distinguished by an atypical configuration: the outdoor unit was installed under a parking shelter , requiring careful planning to ensure adequate air circulation and the safety of the vehicle parked nearby .
Context and choice of system
The client wanted to upgrade their existing HVAC system to a more energy-efficient solution that could provide year-round heating and cooling . After analyzing the building's layout and space constraints, our team recommended the Gree Flexx Ultra R32 – 3 tons , known for its inverter compressor technology , performance down to -30°C , and compatibility with Quebec grant programs .
Features of the installation
The outdoor unit was suspended from a concrete slab , with a threaded rod support and anti-vibration dampers to eliminate sound resonances. This type of mounting, often used in covered parking lots, allows for optimizing floor space while maintaining ventilation of the condenser.
We also have:
-
added reinforced insulating sleeves on the refrigeration ducts;
-
fixed a defrost guard under the unit to prevent any ice build-up;
-
installed metal-sheathed wiring for maximum durability;
-
checked the minimum clearance required around the fan for optimal performance.
Technical challenges met
The main challenge was the ceiling height limitation . To address this, our technicians adjusted the length of the suspension rods and chose a precise drainage angle for gravity condensation . The installation was thus carried out without altering the concrete structure, while respecting Gree standards and the building code.
Final result
The client now benefits from stable, quiet, and economical comfort . Thanks to R-32 technology, this heat pump reduces the carbon footprint while offering energy efficiency greater than 18 SEER. This project perfectly illustrates our ability to adapt each AirGreen installation to the specificities of the Greater Montreal residential environment.
