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.
A New Level of Comfort in Boucherville: The SHARP ZU1 Installation
At AirGreen, we take immense pride in every project, and our latest installation in Boucherville is no exception. Our mission: to deliver maximum comfort and efficiency, even in the harshest Canadian winters. This time, we brought our expertise to the forefront by installing an 18,000 BTU SHARP ZU1 Mini Split Heat Pump, a unit synonymous with advanced technology and exceptional performance.
Understanding the Unique Needs of This Project
Boucherville’s climate demands a heat pump that can handle both extreme cold and sweltering heat, ensuring year-round comfort. The SHARP ZU1 Mini Split, with a heating capacity down to an impressive -27°C, is engineered for exactly these conditions. But let’s dive into the specifics and see why this installation stands out.
Why the SHARP ZU1 Mini Split Is Perfect for Boucherville
Advanced Technology for Extreme Cold
Montreal winters are notorious, but the SHARP ZU1 doesn’t just endure them; it thrives. With 24.0 SEER cooling efficiency and a robust HSPF of 13, this unit is an energy marvel. Even as temperatures plunge to -27°C, it continues to deliver warmth, efficiently distributing heat throughout the home.
- Heating Capacity: Engineered to withstand frigid temperatures, the SHARP ZU1 pumps out warmth reliably, making it a top choice for families braving Boucherville’s winter chill.
- Plasmacluster Ion Technology: This unique feature purifies the air, combating viruses, mold, and allergens. It doesn’t just heat and cool; it creates a healthier indoor environment, a must for anyone valuing clean air.
The Details of Our Installation Process
Our meticulous team handled the installation with the precision and care that AirGreen is known for. We started by positioning the indoor unit strategically for optimal airflow. Given the unit’s dimensions of 41.42 x 9.80 x 12.44 inches, finding the right location was crucial to maintain both aesthetics and functionality.
Exterior Unit Placement
The outdoor unit, with a compact size of 33.47 x 13 x 27.94 inches, was mounted with careful consideration. We ensured it was protected from the elements yet easily accessible for future maintenance. This setup helps keep the sound pressure level minimal, with the indoor unit operating as low as 25 dB(A)—practically a whisper.
- Sound Pressure Control: The SHARP ZU1 is designed for quiet performance, so our client in Boucherville can enjoy peace and comfort without the usual noise disruptions.
- Eco-Friendly Refrigerant R-32: With environmental concerns becoming increasingly important, the SHARP ZU1 uses R-32 refrigerant, which has a lower impact on global warming.
Benefitting from the Highest Hydro-Québec Grant
We’re thrilled to share that this installation qualifies for the highest LogisVert Grant of $2,640—a fantastic incentive for homeowners looking to upgrade their HVAC systems. This grant makes choosing a high-efficiency heat pump not just a matter of comfort but a wise financial decision.
Efficiency and Design: A Match Made for Modern Homes
The SHARP ZU1 combines sleek design with cutting-edge technology. From its Wi-Fi integration for remote control to its customizable settings, it’s all about making life simpler and more comfortable. Here’s what makes this model truly exceptional:
- Integrated Wi-Fi Control: Manage your home’s temperature from anywhere using your smartphone. Heading back home? Turn on the heat before you arrive for a warm welcome.

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. The aid shown is today’s, using Hydro-Québec’s rule ($120 per 1,000 BTU/h at −8 °C); amounts quoted in the article date from its publication. Only Hydro-Québec confirms the assistance granted.
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.
