Careful installation of a Sharp heat pump from AirGreen
In a typical duplex in the Rosemont–La Petite-Patrie district of Montreal , our AirGreen team carried out the complete installation of a Sharp ZU1 wall-mounted heat pump — a new generation model operating with R-32 refrigerant , known for its energy efficiency and performance at very low temperatures .
The project involved offering the client four-season comfort in a dense urban space, while maintaining aesthetic discretion on the building's traditional red brick facade.
Exemplary external integration
The Sharp Eco Inverter condenser has been securely mounted on galvanized wall brackets , above ground level to ensure optimum protection against snow and moisture .
The installation includes a CSA approved electrical disconnect box , mounted directly near the unit for quick access during maintenance.
The refrigeration connections were carefully sheathed using brick-colored capping , blending perfectly with the existing facade. The result: a complex that is both robust, aesthetically pleasing and compliant with RBQ standards .
Sharp ZU1: performance and PlasmaCluster technology
The Sharp ZU1 series is distinguished by its Japanese Inverter compressor and its Plasmacluster Ion system, a patented technology that purifies the ambient air by eliminating particles, allergens and bacteria.
This wall-mounted heat pump combines efficient heating in winter and gentle air conditioning in summer , while improving indoor air quality — a much-appreciated asset in Montreal's urban environments.
Key features of the Sharp ZU1:
-
Capacity : 12,000 BTU
-
Eco-friendly refrigerant R-32
-
Energy efficiency : SEER2 23 / HSPF2 11
-
Operation down to −25°C
-
Plasmacluster technology for healthier air
-
Quiet mode (<22 dB) ideal for bedrooms and small spaces
A high-energy-efficiency residential project
The client, owner of a Montreal duplex, was looking for a replacement solution for his old air conditioner operating on R-410A.
Our team suggested the Sharp ZU1 , a smart choice offering:
-
reduced energy consumption ,
-
compatibility with LogisVert subsidy programs ,
-
and increased durability thanks to high-end components.
This installation now provides stable and economical heating , even during the bitter cold of January, while ensuring rapid cooling during heatwaves.
An installation that complies with the standards and aesthetics of the building
The typical residential environment of Rosemont–La Petite-Patrie —with its brick facades and green alleys—required a careful approach.
Our technicians planned the refrigeration duct route to minimize their visibility, while respecting the mandatory technical clearances to ensure optimal airflow around the condenser.
The result is a functional, silent and visually harmonious installation, faithful to the AirGreen philosophy: performance and design go hand in hand .
