An HVAC installation project by AirGreen: performance, aesthetics and reliability combined
At AirGreen , each wall-mounted heat pump installation is designed to combine energy efficiency , aesthetics, and durability . This project, carried out in the residential sector of Chomedey, in Laval , perfectly illustrates our commitment to offering high-performance, high-quality HVAC solutions tailored to the specific needs of our customers.
A Sharp ZU1 heat pump: Japanese technology serving Quebec comfort
The heart of this installation is a Sharp ZU1 wall-mounted heat pump , from the Eco Inverter range. This series is distinguished by its inverter compressor technology , its high energy efficiency , and its ability to operate down to −25 °C , guaranteeing constant comfort throughout the year.
Sharp's patented Plasmacluster Ion technology actively purifies indoor air by neutralizing airborne particles, allergens, and odors—a major benefit for urban homes where air quality is paramount.
Project context: a modern condo requiring a compact and quiet installation
The client, owner of a recent condo in Chomedey , wanted to replace a portable air conditioner with a fixed, discreet and energy-efficient solution. The goal: to improve thermal comfort while reducing the electricity bill , particularly during peak periods.
As the available outdoor space was limited, our team opted for mounting on a reinforced galvanized steel wall bracket , guaranteeing stability and optimal air circulation, while preserving the balcony slab.
Key steps of installation
1. Technical study and identification
Before any installation, our technicians conducted a site analysis , including proximity to the electrical panel and the ideal path for the refrigerant lines . The chosen location allowed for gravity drainage of condensate and a short pipe run—a guarantee of increased energy efficiency.
2. Installation of the external compressor
The Sharp Eco Inverter condenser is mounted on a metal base with silent blocks to absorb vibrations and reduce noise. The stainless steel fasteners ensure excellent weather resistance, essential in a climate like Quebec's.
3. Installation of conduits and connections
The power and communication cables , as well as the R-32 refrigerant lines , were routed through discreet white capping , perfectly aligned with the façade. This attention to detail ensures harmonious integration with the building's aesthetics.
4. Testing and commissioning
Once the connections were made, a pressure test and a full vacuum confirmed the absence of leaks. The system was then commissioned and calibrated for optimal operation in heating and cooling mode.

Technical challenges and solutions
The main challenge of this project was the limited space of the balcony and the proximity of a window , limiting the air release options. Our technicians circumvented this constraint by using a raised wall configuration , ensuring smooth air circulation and reduced vibration transfer.
A sealed outdoor circuit breaker has been added nearby for electrical safety that meets Canadian Electrical Code standards, while facilitating future maintenance.
An investment eligible for energy subsidies
Because the Sharp ZU1 is Energy Star certified and uses R-32 refrigerant , it is eligible for several financial assistance programs available to homeowners in Greater Montreal, including those from Hydro-Québec and the Rénoclimat program. These grants can significantly reduce the cost of acquisition and installation.
Final result: 4-season Japanese comfort
The customer now benefits from stable thermal comfort throughout the year: gentle warmth in winter, rapid cooling in summer, and superior air quality thanks to Plasmacluster technology.
At AirGreen, we believe that every HVAC project should combine performance, durability, and elegance . This installation in Chomedey, Laval , is a perfect example of this—precise, clean, and durable work.
