A wall-mounted heat pump installation designed for lasting comfort
At AirGreen , we recently installed a Sharp ZU1 wall-mounted heat pump in a residential building in the Sainte-Dorothée sector of Laval , a green neighborhood where indoor comfort must adapt to the harsh winters and humid summers of Greater Montreal. This installation perfectly illustrates our approach: energy efficiency, aesthetic discretion and technical sustainability .
High-performance equipment from Sharp
The Sharp ZU1 is a new generation wall-mounted heat pump using R-32 refrigerant , renowned for its exceptional performance down to -25°C . It combines inverter technology , ultra-quiet operation and a compact design , ideal for single-family homes on the North Shore.
Thanks to its Eco Inverter compressor, the ZU1 automatically adjusts its power to maintain a stable temperature while reducing electricity consumption. The result: constant comfort and a lower energy bill .
Technical details and specific features of the project
For this residence with beige vinyl cladding , our team opted for an installation on a raised galvanized steel support , an essential solution for:
-
protect the condenser from the accumulation of snow and water on the ground;
-
ensure optimal air circulation ;
-
facilitate future maintenance operations.
The electrical wiring and refrigerant lines were carefully concealed in white capping , perfectly integrated into the facade.
Condensate is drained by gravity , thus avoiding the use of a pump and simplifying annual maintenance.
The outdoor unit rests on stabilized concrete slabs , ensuring the solidity of the installation and minimizing vibrations. As always, we have respected the minimum clearance distances to preserve the airflow performance and the durability of the compressor.
A planned and controlled intervention
The installation was completed in just one day:
-
Preparation and anchoring of supports ;
-
Precise wall drilling for pipes;
-
Connection of the refrigeration circuit ;
-
Pressure testing, vacuum testing and performance testing ;
-
Complete commissioning and verification of proper operation .
Our RBQ and CMMTQ certified technicians have validated each step according to the standards of the Quebec Building Code and AirGreen best practices .
Result: maximum efficiency in all seasons
The owner now enjoys four-season comfort , with stable heating capacity even at -25°C , and gentle, quiet air conditioning during the summer.
Thanks to R-32 technology, this installation reduces its environmental footprint while maximizing eligibility for provincial subsidies offered under the Rénoclimat program.
