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 Reliable Heating and Cooling Solution for Homes in Boucherville
At AirGreen, we’re passionate about delivering top-notch HVAC solutions across Montreal, Laval, Longueuil, and both the Rive Nord and Rive Sud. Today, we’re excited to showcase our recent installation of a Sharp ZU1 Wall-Mounted Heat Pump—an impressive 18,000 BTU unit that perfectly marries innovation, efficiency, and comfort.
Installed in Boucherville, this cutting-edge mini split system doesn’t just heat or cool—it transforms the living experience. Homeowners are increasingly opting for the Sharp ZU1 model thanks to its combination of eco-friendly technology and performance-driven features.
Why the Sharp ZU1 Heat Pump is Ideal for Québec Winters

- Unmatched Heating Capacity: Works flawlessly in outdoor temperatures as low as -27°C.
- Efficiency: An impressive 24.0 SEER rating ensures energy savings while maintaining a comfortable home environment.
- Environmentally Friendly: The ZU1 uses the new R-32 refrigerant, aligning with 2025 energy efficiency regulations while reducing your carbon footprint.
- Sound Levels: Silent operation with an indoor sound pressure level of 25 to 49 dB(A)—barely louder than a whisper.
- Smart WiFi Integration: Control your heat pump remotely using an intuitive smartphone app.
Our team at AirGreen ensured a meticulous installation process, factoring in every detail to optimize performance and longevity.
What Makes This Installation Unique
The client, a family in Boucherville, reached out to us looking for an energy-efficient system that could handle Québec’s harsh winters. With a focus on keeping their home cozy during the coldest months and cool during summer heatwaves, we recommended the Sharp ZU1 18,000 BTU wall-mounted heat pump.
This model not only saves on energy costs but also qualifies for the highest grant in Québec—a remarkable $2,640 LogisVert Grant by Hydro-Québec! This grant, combined with the system’s federal eligibility of up to $5,000, makes the Sharp ZU1 an attractive choice for homeowners looking to upgrade their HVAC systems.

Top Features That Elevate the Sharp ZU1 Heat Pump
Plasmacluster Technology: A Breath of Fresh Air
One of the Sharp ZU1’s most unique features is Plasmacluster Technology. Unlike other heat pumps on the market, the Sharp ZU1 actively purifies indoor air by:
- Eliminating airborne viruses and allergens.
- Neutralizing mold and odors.
- Breaking down contaminants and creating a healthier living environment.
This feature was especially appealing to the client, who wanted cleaner, fresher air for their family.
Coanda Airflow Control: Uniform Comfort
With its Coanda effect-inspired airflow control, the Sharp ZU1 distributes air more evenly across the home. Warm air flows downward in the winter, while cool air rises during summer—ensuring consistent comfort without direct drafts.
Defrost Technology for Extreme Winters
Winter temperatures in Boucherville can be unforgiving, often requiring heat pumps to defrost frequently. The Sharp ZU1’s advanced defrost system reduces downtime by up to 60%, maintaining indoor warmth without interruption.
A Future-Proof Investment with AirGreen
We pride ourselves on offering HVAC solutions that are both reliable and forward-thinking. The Sharp ZU1 wall-mounted heat pump is a prime example. With inverter technology to optimize energy use, this system minimizes operating costs while providing maximum comfort.
Additionally, the multi-space feature allows air distribution across multiple rooms, ensuring no corner is left too hot or cold. This was a game-changer for the family’s open-concept living space, which now enjoys balanced temperatures year-round.

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.
