A high-end comfort solution for a condo on Nuns' Island, by AirGreen
Nestled between peaceful greenery and panoramic views of the river, Nuns' Island is a place where thermal comfort should never be compromised. It is precisely in this refined residential context that our team at AirGreen recently completed the installation of a SHARP ZU1 18,000 BTU wall-mounted heat pump , a high-performance model that combines energy efficiency, climatic comfort, and discreet aesthetics.

A perfectly mastered logistical challenge
From the site analysis, we were faced with several technical elements: complex access at height, a demanding brick facade for fixing the wall support, and the need to preserve the visual integrity of the co-ownership. To meet these requirements, we used a secure lifting platform , protected the anchor points with anti-vibration material, and carefully concealed the refrigeration piping under a high-quality aesthetic cover .
The client, owner of a large two-story condo, was looking for a reliable heating and cooling solution to ensure comfort all year round, even in the middle of Montreal's winter. After a comparative analysis of several options, the SHARP ZU1 , with its heating capacity down to -27°C , emerged as the best solution.
