Precision installation for lasting comfort
At AirGreen , every installation is a promise of comfort, efficiency, and peace of mind. Recently, our team completed the installation of a Sharp ZU1 wall-mounted heat pump in a single-family residence in the Sainte-Dorothée district of Laval , an area known for its modern homes and efficient air conditioning and heating needs throughout the year.
A wise choice: the Sharp ZU1, synonymous with performance and reliability
The Sharp ZU1 is one of our customers' most popular models for its exceptional energy efficiency and energy-saving inversion technology (Eco Inverter). It offers stable performance down to -25°C , making it perfectly suited to the Quebec climate. Its variable-speed compressor ensures constant comfort, reduced consumption, and remarkably quiet operation.
This outdoor unit, visible in the photo, is mounted on a raised aluminum support , ensuring good air circulation and optimal protection against snow and humidity. The gravity condensate pipe has been carefully directed to the outside, avoiding any stagnation of water near the foundation—an often overlooked detail, but essential to the durability of the system.
Technical details and installation context
This installation was carried out on a smooth concrete side facade , adjacent to a window with a blue metallic frame , typical of contemporary constructions in the Laval area. This choice of location offers several advantages:
-
excellent ventilation of the condenser , away from areas of heat accumulation;
-
easy access for maintenance and future interventions;
-
natural sound insulation from living spaces.
The wall passage for the refrigerant and electrical lines was neatly executed, with a waterproof cap on the inside. The refrigeration line, protected by discreet and insulated wiring , ensures optimal thermal efficiency.
The indoor unit, installed in the living room, benefits from an ideal position for uniform air diffusion . Thanks to Sharp's exclusive Plasmacluster Ion system, the air is continuously purified, eliminating bacteria, allergens and odors. A feature particularly appreciated by families seeking a healthier indoor environment.
