Why the SHARP ZHU1 is a Game-Changer for Montreal Homes
Impressive Energy Efficiency with R-32 Refrigerant
At AirGreen, we understand the importance of energy conservation and sustainability. The SHARP ZHU1 uses R-32 refrigerant, a cutting-edge alternative with a significantly lower global warming potential compared to older refrigerants like R-22. Not only does this refrigerant improve the unit’s energy efficiency by 10%, but it also reduces the overall environmental footprint—ideal for eco-conscious homeowners in Montréal.
Optimal Performance in Extreme Cold
Montréal winters can be brutal, but the SHARP ZHU1 thrives even in sub-zero temperatures. With a heating capacity that remains efficient down to -27°C, this mini split ensures uninterrupted warmth throughout the chilliest months. Whether battling a deep freeze or enjoying mild spring days, this unit delivers consistent, reliable comfort.
Ultra-Quiet Operation
Home comfort isn’t just about temperature; noise levels play a significant role too. With sound pressure levels as low as 22 dB(A) for indoor operation and 49 dB(A) outdoors, the SHARP ZHU1 operates almost silently, allowing homeowners to enjoy peace and quiet alongside perfect climate control.

The Installation: A Blend of Expertise and Precision
The installation process in Montréal was meticulously planned to ensure maximum efficiency and aesthetics. The outdoor unit, measuring 30.72 x 10.59 x 21.25 inches, was securely mounted on the rooftop using specialized supports to guarantee stability and durability against wind and weather. The indoor unit, with dimensions of 41.42 x 9.80 x 12.44 inches, was installed in a central location to maximize airflow distribution across the space.
Our team ensured seamless connectivity between the indoor and outdoor units using high-quality 1/4" and 3/8" piping, and we double-checked all electrical connections to align with the unit’s 220V voltage requirement. Every detail, from the placement of the units to the calibration of the airflow, was handled with care to deliver optimal performance.
Advanced Features That Set the SHARP ZHU1 Apart
Plasmacluster Air Purification
One of the standout features of the SHARP ZHU1 is its Plasmacluster technology, which purifies the air by neutralizing airborne bacteria, viruses, and mold. This system mimics nature’s ion balance to create cleaner, healthier indoor air, making it a perfect choice for families and individuals with allergies or respiratory sensitivities.
Nature-Inspired Fan Blade Design
The SHARP ZHU1’s fan blades are inspired by the natural shapes of dragonfly wings, golden eagles, and albatrosses. These innovative designs improve airflow efficiency by up to 30%, reducing energy consumption while ensuring powerful, consistent airflow.
Coanda Airflow Control
With Coanda technology, the SHARP ZHU1 strategically directs airflow along walls and ceilings, ensuring even temperature distribution throughout the room. This eliminates cold drafts and creates a balanced, comfortable environment.
Smart Connectivity
The unit’s WiFi-enabled controls allow homeowners to monitor and adjust settings remotely. Features like real-time temperature and humidity monitoring, energy consumption tracking, and motion-sensor notifications make this system as intelligent as it is efficient.

The job tools
Two quick checks with real numbers: what heat costs, and what your current heaters add up to in BTU/h.
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.
