A meticulous installation tailored to the needs of an apartment in Saint-Lambert
At AirGreen, we apply our expertise to every client, no matter the complexity or layout of the space to be cooled or heated. This installation in an apartment in Saint-Lambert, on the South Shore of Montréal, perfectly showcases our custom and professional approach. The client was looking for an energy-efficient, quiet solution that could perform well during Québec’s harsh winters, while providing excellent comfort in the summer.
We recommended installing a SHARP ZU1 12,000 BTU wall-mounted heat pump, a model known for its reliability, energy efficiency and advanced technologies like Plasmacluster. Here’s a detailed look at this strategic installation and the many benefits of this system.
Why the SHARP ZU1 is ideal for small residential spaces
The SHARP ZU1 12,000 BTU wall-mounted heat pump is perfectly suited for medium-sized homes, such as apartments and condos. Here’s why we recommended it for this project in Saint-Lambert:
Power perfectly suited to the space
With a 12,000 BTU capacity, this unit provides balanced performance for heating or cooling areas around 400 to 550 square feet. It maintains a comfortable indoor temperature year-round, even during extreme cold.
Excellent performance in low temperatures
This model performs efficiently down to -27°C, which is crucial for the winters in Greater Montréal, especially on the South Shore. At that temperature, the SHARP ZU1 still delivers 7,200 BTU/h of heat, outperforming many competitors in its class.
R-32 refrigerant
This unit uses R-32 refrigerant, which delivers better energy efficiency and has a lower environmental impact (lower global warming potential compared to R-410A). It’s the right choice for homeowners who care about choosing greener technologies.
Installation details in Saint-Lambert
This project had unique challenges related to the interior layout of the apartment:
Optimal placement above a window
We installed the wall-mounted unit above the window, on a thick interior wall. This strategic placement allowed us to minimize the length of the drain and refrigerant lines, which helped optimize energy performance.
Clean, aesthetic wall installation
The unit was installed with flawless finishing, using discreet line covers that blend perfectly with the interior design. Our technicians paid extra attention to visual details, ensuring a polished result that met the client’s expectations.
Balcony access: simplified logistics even in winter
Although the project took place in the middle of winter, access via the balcony allowed for a safe and efficient installation. With our specialized equipment—like the Gorilla Ladders telescopic ladder—our team completed the outdoor connections safely and quickly.
Key technological advantages of the SHARP ZU1
Exclusive Plasmacluster Technology
This patented air purification technology neutralizes viruses, bacteria, allergens, and even stubborn odors like cooking smells or cigarette smoke. Perfect for people with respiratory sensitivities or indoor air concerns.
Ultra-quiet operation
With indoor noise levels as low as 23 dB, this unit operates silently, ensuring peaceful comfort even in bedrooms or home offices.
Precise airflow control
The SHARP ZU1 allows automatic vertical airflow adjustment, which helps evenly distribute heat in winter and cool air in summer. This prevents that uncomfortable direct draft effect.
Effective dehumidification mode
During humid periods, the automatic dehumidification mode adjusts the room’s humidity level, enhancing comfort and reducing the risk of mold.
Final result: optimized comfort and a satisfied customer
After installation, the client immediately noticed a significant improvement in thermal comfort, both for heating and cooling. Thanks to the Plasmacluster technology, they also observed better indoor air quality, with fewer respiratory irritants.
The system’s energy efficiency, combined with the use of R-32 refrigerant, helps the client lower their electricity bills, while benefiting from a quiet, reliable, and modern system.
