The article, chapter by chapter
At AirGreen, we pride ourselves on delivering top-notch HVAC services across Greater Montreal. Recently, we had the pleasure of installing a Sharp ZU1 Mini Split system at a charming home in Montréal-Nord. This installation not only enhanced the comfort of the home but also showcased the advanced technology and energy efficiency of the Sharp ZU1 model.
A Closer Look at the Sharp ZU1 Mini Split System
The Sharp ZU1 Mini Split, with a cooling capacity of 18,000 BTU, is a powerhouse in providing optimal indoor climate control. Its Energy Star® certification ensures it meets high energy efficiency standards, making it an excellent choice for environmentally conscious homeowners. The system also includes WiFi connectivity, allowing for convenient remote control and monitoring.
Unique Features and Benefits
Plasmacluster Technology
One of the standout features of the Sharp ZU1 is its Plasmacluster technology, a unique air purification system. This technology releases positive and negative ions into the air, neutralizing airborne viruses, bacteria, and allergens. It ensures that the indoor air quality remains high, providing a healthier living environment.
- Eliminates airborne viruses
- Removes mold and microbes
- Neutralizes odors and allergens
Coanda Airflow Control
The Coanda airflow control feature is another highlight of the Sharp ZU1. This technology guides the airflow along the walls and ceiling, ensuring an even distribution of temperature throughout the room. This prevents uncomfortable drafts and promotes a consistent, comfortable indoor climate.
Energy Efficiency and R-32 Refrigerant
The Sharp ZU1 uses the R-32 refrigerant, which is more efficient and has a lower global warming potential compared to traditional refrigerants. This contributes to the system’s impressive 24.0 SEER (Seasonal Energy Efficiency Ratio), ensuring lower energy consumption and reduced utility bills. The unit operates efficiently even in extreme temperatures, with a heating capacity that functions down to -27°C.
Durable and Quiet Operation
The Sharp ZU1 is designed for durability and quiet operation. With a sound pressure level of 25 dB(A) indoors, it provides a peaceful environment, perfect for any home setting. The system also includes an anticorrosive coating on the compressor, ensuring long-lasting performance.
Installation Details and Customer Satisfaction
During the installation in Montréal-Nord, our team ensured that the Sharp ZU1 system was seamlessly integrated into the home's layout. We paid close attention to the placement of the indoor and outdoor units, optimizing both performance and aesthetics. The installation included:
- Properly sizing and running refrigerant pipes (1/4 - 3/8)
- Ensuring a secure electrical connection with a voltage of 220V
- Setting up the WiFi connection for easy control via smartphone
- Ensuring proper drainage with multiple drainage holes to prevent water pooling and freezing
Our team also provided the homeowners with a comprehensive overview of the system's features, ensuring they felt confident in using and maintaining their new Sharp ZU1 Mini Split. The homeowners were particularly pleased with the LogisVert Grant by Hydro-Québec, which offered a $2640 grant for choosing this energy-efficient model.
The Future of Home Comfort with Sharp ZU1
The Sharp ZU1 Mini Split is a testament to modern HVAC technology, offering unparalleled comfort, efficiency, and air quality. Its advanced features, including the Plasmacluster technology and Coanda airflow control, make it a top choice for homeowners looking to upgrade their heating and cooling systems.
At AirGreen, we are committed to providing our customers with the best HVAC solutions available. The Sharp ZU1 installation in Montréal-Nord is just one example of how we deliver high-quality service and innovative products. We look forward to helping more homeowners experience the benefits of advanced HVAC technology.
The job tools
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.
How the job unfolds
The main steps of this kind of job at AirGreen. Every house has its quirks: the estimate brings them out.
We look at the room, the outside wall, the line route and where the outdoor unit will go. That is where the capacity gets chosen.
Model, capacity and price, in writing. We also check whether the model qualifies for assistance programs.
Floors and furniture protected, wall plate position marked level, wall opening located.
A single opening, with the slope the drain needs to flow outside.
Set on a stand raised above the snow, with the clearances the manufacturer requires.
Connected, insulated and protected. The opening is then sealed against water, cold air and insects.
A dedicated circuit and an accessible disconnect near the outdoor unit.
Leak test, vacuum, then start-up and a check of heating and cooling.
Remote, modes, filters: we show you the essentials before we leave.

What we check on a job like this one
Each number is a point we check on site. Switch between summer and winter to watch air and heat move.
In summer, the outdoor unit rejects the house's heat outside.
Generic illustration of this type of installation, not a survey of this job site. Tap a number.
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.
Is your home ready?
Check what applies at your place. A "no" is not a refusal: it is what we sort out during the estimate.
Good habits, once the unit is in place
Six simple habits that keep the unit going. Your list stays on this device.
What to do, season by season
Three habits per season for this unit. They take a few minutes and prevent many calls.
- Clean the indoor unit's filters.
- Clear leaves and debris left on the outdoor unit by winter.
- Test cooling before the first hot days.
- Clean the filters more often when the unit runs a lot.
- Keep plants away from the outdoor unit.
- Check that no water drips from the indoor unit.
- Rake the leaves around the outdoor unit.
- Test heating before the first cold days.
- Book periodic maintenance before winter.
- Keep snow away from the stand and the front of the unit.
- Let the unit defrost: it is normal.
- Never hit the ice on the fins; call us if the unit stays iced up.
The right pages, at the right time
Four statements: true or false?
It all comes down to details you have just seen.
1. In heating mode, the outdoor unit can produce water.
During defrost cycles. That water must drain away without forming ice.
2. You pick the capacity with a simple square-footage rule.
Windows, insulation, orientation and how the room is used all count. Capacity is chosen on site.
3. A multi-zone connects several indoor heads to a single condenser.
One head per room, all on the same condenser. Each room keeps its own temperature.
4. The disconnect can sit behind the patio furniture.
It must stay accessible: it is what shuts the unit off for service.
