A high-end heating and cooling solution for year-round comfort
In the peaceful city of Saint-Jean-sur-Richelieu, known for its harsh winters and hot, humid summers, the need for residential thermal comfort is a top priority. It is in this context that AirGreen had the privilege of installing a SHARP ZU1 18,000 BTU wall-mounted heat pump, a model that combines performance and innovation, in a top-floor apartment with a balcony.
Here, we share the technical and practical details of this installation, while highlighting the tangible benefits for the customer and the standout features of this high-performance unit by SHARP.
Installation details: optimized space and a solid mounting system
Strategic placement on a metal balcony
The outdoor unit was firmly mounted on a raised wall bracket, directly on the back balcony. This technical decision allowed us to:
-
Avoid snow and ice accumulation during winter;
-
Improve airflow around the compressor;
-
Reduce vibration transfer to the building structure.
The balcony floor, made of a metal platform and wooden tiles, also made technician access easy, allowing for a quick and safe installation.
