A fully integrated HVAC solution with cutting-edge technology for a peaceful living space in Sainte-Marthe-sur-le-Lac
At AirGreen, we had the pleasure of completing a new installation of a SHARP ZU1 12,000 BTU wall-mounted heat pump in a lovely residence located in Sainte-Marthe-sur-le-Lac, on the North Shore of Montréal. This project perfectly illustrates our commitment to home comfort, energy efficiency, and indoor air quality.
A compact space, maximum efficiency
From our initial visit, we saw that the target area—a beautifully arranged dining nook—was modest in size, but required consistent thermal comfort year-round. The choice of the SHARP ZU1, renowned for its versatility and ability to adapt to small to medium-sized rooms, was the obvious choice.
The wall-mounted unit was installed in an optimal high position, on a central wall with no obstructions, ensuring even airflow distribution throughout the room. Its sleek white finish fits perfectly with the space’s minimalist aesthetic.
Why choose the SHARP ZU1 12,000 BTU?
Reliable thermal performance in any condition
The SHARP ZU1 12,000 BTU, powered by a variable-speed compressor and using R-32 refrigerant (environmentally friendly), delivers outstanding performance—even in extreme climate conditions. This unit can maintain steady heating output down to -27°C, which is crucial in our region where winters are severe.
Notable technical specifications:
-
Maximum heating capacity at -27°C: 7,200 BTU/h
-
Nominal capacity: 14,000 BTU (heating), 12,000 BTU (cooling)
-
SEER: 21 / 22
-
HSPF (cold climate): 12.5 / 11

Indoor noise level: as low as 23 dB — ideal for quiet residential environments
Air purification with Plasmacluster technology
This ZU1 model is equipped with SHARP’s exclusive Plasmacluster technology, which emits positive and negative ions to neutralize viruses, bacteria, mold, allergens, and odors. A particularly valuable feature in enclosed living areas like dining rooms, where cooking smells and airborne particles can accumulate.
With this technology, the system acts as an invisible barrier against contaminants while maintaining a fresh and healthy atmosphere.
A clean, fast, and long-lasting installation
Our technicians completed the installation in one full day, paying close attention to the aesthetics and discretion of the outdoor unit and wiring. The PVC line cover was painted white to match the interior wall, making the installation nearly invisible.
We also made sure to check the drainage slope, conduct a leak test on the refrigerant lines, and program personalized comfort schedules based on the customer’s lifestyle.
Peace of mind guaranteed
SHARP wall-mounted heat pumps come with a 10-year warranty on the compressor, parts, and labor, offering our customers long-term peace of mind. At AirGreen, we support our clients every step of the way—from quote to installation, including handling grant applications.
