A precision installation by AirGreen on a flat roof in Montreal
In the residential neighborhood of Rosemont–La Petite-Patrie , our AirGreen team recently installed a Sharp ZU1 wall-mounted heat pump , a model renowned for its energy efficiency and reliability in the Quebec climate. The project took place on a typical Montreal plex flat roof , requiring careful planning to ensure stability, durability, and optimal performance in an environment exposed to the elements.
A high-performance Sharp heat pump adapted to the Quebec climate
The Sharp ZU1 model is equipped with an R-32 technology inverter compressor , allowing it to offer stable performance even in very low temperatures, down to −25 °C . This wall-mounted heat pump is distinguished by its low energy consumption , its quiet operation and its ability to heat and cool efficiently throughout the year.
Sharp's choice is based on reliability and durability. This Energy Star -certified model is eligible for provincial energy transition grant programs , a significant advantage for homeowners looking to save on their heating costs.
A flat roof installation: stability and safety above all
For this Plateau Est residence, our team opted for an installation on aluminum supports with anti-vibration pads . The Sharp condenser was securely fixed to a treated wood structure placed on an insulating base to prevent any direct contact with the roof membrane . This system protects both the heat pump and the building's waterproofing.
The refrigeration lines have been carefully insulated and sheathed , ensuring protection against temperature variations and water infiltration . The wiring and drain routing has been optimized to minimize visual impact while ensuring easy access for future maintenance.
Technical challenges encountered and AirGreen solutions
The main challenge of this installation was the flat roof configuration and the proximity of a skylight . Our technicians adjusted the position of the condenser to avoid any obstruction of natural light while respecting the safety clearances required for the ventilation of the unit.
In addition, the condensate drainage system was installed in gravity mode , thus avoiding the need for an additional pump. This choice ensures better long-term reliability and reduces the need for maintenance.
An impeccable result: efficiency and aesthetic integration
Once the installation was complete, the Sharp ZU1 system was tested and calibrated to ensure optimal operation in both cooling and heating mode. The customer now benefits from consistent indoor comfort and reduced energy bills , while having a discreet and safety-compliant outdoor installation.
This achievement perfectly illustrates our expertise in implementing tailor-made HVAC solutions for complex urban environments like those of Montreal.
