An installation designed for comfort, performance, and energy efficiency—even in extreme cold
At AirGreen, we recently had the pleasure of completing the installation of a wall-mounted Sharp ZU1 18000 BTU heat pump in a bright, modern home located in Sainte-Dorothée, Laval. This project perfectly illustrates our approach: meticulous service, tailored to the customer’s needs, with a high-performance, eco-friendly unit built to handle the challenges of Québec’s climate, especially on the North Shore.
A living room with sloped ceilings and large windows: a challenge met with precision
The environment of this installation was far from ordinary: the home’s main living space features cathedral ceilings and large southwest-facing windows, creating significant solar gain in the summer and heat loss in the winter. The choice of the Sharp ZU1 18000 BTU heat pump, paired with a thoughtfully elevated installation, enables even air distribution and precise temperature control throughout the space.
We installed the indoor unit on the highest wall, in a strategic position that maximizes the Coanda effect (a natural phenomenon used to guide airflow along surfaces), avoiding direct airflow while optimizing thermal comfort in the main living area.
Sharp ZU1: advanced technology serving your comfort
The Sharp ZU1 wall-mounted heat pump is not your typical wall unit. It includes several cutting-edge features that place it among the best options on the market for demanding climates like ours in Québec.
Technical specifications of the Sharp ZU1 18000 BTU:
-
Heating capacity: up to 25,600 BTU/h, with reliable performance down to -27°C.
-
SEER (cooling seasonal efficiency ratio): 24
-
HSPF (heating seasonal performance factor): up to 13 / 11 (Zone IV/V)
-
Refrigerant: R-32, more eco-friendly than R-410A, with a lower global warming potential (GWP).
-
Plasmacluster technology: neutralizes airborne viruses, bacteria, mold, and allergens.
-
Triple filtration system: washable pre-filter, antimicrobial HEPA filter, and activated carbon deodorizing filter.
-
Sleek, discreet design with wide, quiet airflow (as low as 25 dB in silent mode).
-
Built-in Wi-Fi connectivity for smart control via mobile phone.
Year-round comfort, even at -27°C
The standout benefit of this Sharp wall-mounted heat pump is its ability to deliver consistent and reliable heating performance, even when outdoor temperatures drop well below -20°C. This makes it perfect for winters in Laval, where harsh cold is the norm.
Thanks to its patented Hot Gas Pipe system, the unit is designed to drain condensation efficiently, preventing freezing in the outdoor unit and maintaining consistent performance, even during defrost cycles.
A clean, fast, and personalized installation
The Sainte-Dorothée installation was completed in a single day, with no disruption to the homeowners’ routine. Access to the outdoor unit was planned according to the balcony layout, and drainage was optimized for cold climate operation. We also ensured a properly sealed wall penetration and protection against air infiltration.
Indoors, the unit was mounted on a load-bearing drywall with anti-vibration supports for ultra-quiet operation. The refrigerant line was discreetly concealed to match the room’s clean and minimalist aesthetic.
