A careful installation for lasting comfort in a bright residential environment
At AirGreen , we recently completed the installation of a Sharp ZU1 wall-mounted heat pump in a residence in the Chomedey district of Laval , an area known for its family homes and large, bright spaces. This intervention perfectly illustrates our commitment to offering reliable, aesthetic and efficient HVAC solutions, adapted to Quebec's harsh climate.
A compact and powerful device: the Sharp ZU1
The Sharp ZU1 is a high-performance wall-mounted heat pump that uses R-32 refrigerant, a more environmentally friendly and energy-efficient gas. This range is distinguished by:
-
A stable heating capacity down to −25°C , ideal for our Quebec winters;
-
Superior energy efficiency (high SEER and optimized HSPF);
-
Quiet operation , perfect for a living room or bedroom;
-
Sharp's exclusive Plasmacluster™ air purification system improves indoor air quality.
These features make the Sharp ZU1 an excellent choice for homeowners looking to improve their comfort while reducing their energy consumption .
The context of the project
The owner of this Chomedey residence wanted to replace an old wall-mounted air conditioner with a four-season solution capable of providing both heating and cooling. The goal: to maximize indoor comfort while reducing dependence on the main electric heater.
The chosen installation space was located above a large south-facing window , which required careful attention to air circulation and heat management to ensure optimal performance without hindering the diffusion of cold air in summer or hot air in winter.
Key steps of installation
Our RBQ and CCQ certified technicians carried out a complete turnkey installation , including:
-
Precise positioning of the inner head
The Sharp wall unit was installed at a strategic height to ensure even air distribution throughout the room. The proximity to the ceiling required precise adjustment to avoid any vibration or resonance. -
Passage of refrigeration connections and wiring
The ducts were carefully concealed behind a white finishing cover (capping) matching the wall color, ensuring impeccable aesthetic integration . The approximate line length, about 3.5 meters , allowed a direct connection to the outdoor compressor without intermediate joints. -
Condensate drainage management
A gravity drain was installed, allowing the natural evacuation of condensates without a pump. This method guarantees less maintenance and noise , while extending the life of the system. -
Electrical connection and commissioning
The dedicated power supply, protected by a circuit breaker that complies with current standards, was checked before start-up. The AirGreen team then proceeded to evacuate the circuit , charge the refrigerant in accordance with the manufacturer , then calibrate the remote control and perform functional tests .
A discreet and effective result
The end result offers a discreet, modern and highly functional installation. The Sharp unit blends perfectly into the room thanks to its sleek finish and compact size.
During testing, the heat pump quickly reached the set temperature, with a barely perceptible noise level , proof of Sharp's engineering quality and the know-how of our installers.
