Mounted level on a wall plate, high enough for the air to reach the whole room, with enough space around it to slide the filters out easily.
The refrigerant lines, the communication cable and the drain go through the wall in a single opening, sealed against water, cold air and insects.
Two insulated copper pipes connect the two units. Outside, a line cover can protect them from sun, knocks and weather.
A shut-off switch near the outdoor unit isolates it safely for service. It must stay accessible at all times.
The compressor and the fan. In heating mode it captures heat from the outdoor air, even in winter, and moves it inside.
On the ground or on the wall, it keeps the unit above accumulated snow. The unit stays clear and defrost water can drain away.
The fan needs to blow freely. Storage, a fence or a wall too close, and efficiency drops while noise goes up.
Exceptional Comfort for All Seasons: The Sharp ZU1 Mini Split Installation
At AirGreen, we take pride in offering high-quality HVAC solutions to our clients across Montreal, Laval, Longueuil, North Shore, and South Shore. Our recent project in Boisbriand exemplifies this dedication, as we successfully installed a Sharp ZU1 Mini Split system to provide our customer with year-round comfort, energy efficiency, and advanced air purification.
This installation required precision and attention to detail, and it’s not just about placing a machine; it’s about crafting an environment where the family can enjoy a comfortable indoor climate regardless of the weather outside. Let's dive into the details of this exciting project.
Why the Sharp ZU1 is the Ideal Choice
The Sharp ZU1 Mini Split is renowned for its exceptional performance and energy efficiency. With a cooling capacity of 18,000 BTU and heating capabilities down to -27°C, it’s engineered to handle the most extreme Quebec winters. This model is also Energy Star® certified, ensuring that it meets the highest standards for energy efficiency.
One of the standout features of this system is its use of the R-32 refrigerant, which is known for being more environmentally friendly than previous refrigerants, reducing the system's carbon footprint and ensuring compliance with future government energy regulations. As part of our commitment to sustainability, we are proud to offer products like the ZU1, which align with modern environmental standards.
The Installation Process: A Smooth, Seamless Experience
At AirGreen, we prioritize making the installation process as smooth and efficient as possible. For this Boisbriand home, our team conducted a detailed assessment to ensure that the system would be perfectly suited to the space. We installed both the indoor unit and the outdoor compressor in strategic locations, ensuring optimal airflow and performance.
-
Interior Unit: Measuring 41.42 x 9.80 x 12.44, the indoor unit was installed in a living area where it would have maximum impact. Its compact design ensures it doesn’t intrude on the aesthetics of the room while delivering whisper-quiet operation at only 25 dB(A), ensuring that the family can enjoy their comfort without any unnecessary noise.
-
Outdoor Unit: The exterior unit, with dimensions of 33.47 x 13 x 27.94, was placed on a solid foundation outside the home. Despite its robust performance, this unit operates at just 52 dB(A), which is about as loud as a conversation, making it one of the quieter options available on the market.
Key Features of the Sharp ZU1 Mini Split
High-Efficiency Performance
The Sharp ZU1 offers an impressive 24.0 SEER rating, making it one of the most efficient units available. This means lower electricity bills for the homeowner and a more environmentally friendly way to heat and cool their home. In a province like Quebec, where extreme weather can lead to sky-high heating costs, this level of efficiency is a game-changer.
Plasmacluster Air Purification
One of the Sharp ZU1's most unique features is its Plasmacluster technology, which purifies the air by eliminating airborne bacteria, mold, and viruses. For families concerned about air quality, this feature ensures that the indoor environment is not just comfortable but also healthy.
- Removes allergens like pollen and dust.
- Neutralizes viruses and bacteria.
- Reduces odors from pets or tobacco, ensuring the air inside the home remains fresh and clean.
Coanda Airflow for Even Comfort
We know that Quebec homes often have multiple rooms and floors, and maintaining even temperatures across spaces can be a challenge. The Coanda airflow control ensures that hot or cold air is directed throughout the home evenly, reaching every corner and ensuring a consistent, comfortable temperature throughout.
Quiet and Discreet Operation
This Sharp ZU1 Mini Split is designed to be quiet and unobtrusive. The indoor unit operates at a low 25 dB(A), making it quieter than a whisper, while the outdoor compressor is similarly discreet at 52 dB(A). This makes it an ideal choice for homeowners who prioritize a peaceful indoor environment.
Government Grants and Rebates
One of the highlights of this installation is that the Sharp ZU1 Mini Split is eligible for the LogisVert Grant by Hydro-Québec, offering up to $2,640 in rebates. For homeowners looking to upgrade their HVAC system while reducing costs, this grant makes the Sharp ZU1 an even more appealing option.

Data read live from the airgreen.ca page of each size (NEEP / AHRI certified performance). When the title names the installed size, it is highlighted; otherwise the whole range is shown.

And at your place?
Two quick checks with real numbers: what heat costs, and what your current heaters add up to in BTU/h.
Baseboards and electric furnaces turn 1 kWh of electricity into 1 kWh of heat. A heat pump delivers more: that is its COP. At Hydro-Québec’s rate D (11.142¢/kWh above 40 kWh a day, since 1 April 2026):
Hydro-Québec: a heat pump can be up to three times more efficient than baseboards for heating in the colder months.
Estimate per kWh of heat, at the chosen temperature, using the certified COP from the product page. Taxes, access charge and backup heat not included.
Conversion: 1 W = 3.412 BTU/h. An indication, not a load calculation: baseboards and furnaces are often stronger than the real need, and they can stay as backup. AirGreen confirms the capacity on site.
