Take a tour of the installation
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.

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.
Advanced Climate Control for Unpredictable Winters and Hot Summers
In the heart of Montréal-Nord, our team at AirGreen recently completed a top-tier installation of the SHARP ZU1 24,000 BTU Mini Split Heat Pump. This isn’t just any HVAC system; it’s a unit designed to withstand the demanding climate of Quebec, delivering year-round comfort, superior efficiency, and air quality improvements that go beyond mere temperature control. From its sleek design to its advanced capabilities, this SHARP model has been meticulously chosen for its powerful performance, eco-friendliness, and smart technology that resonates with modern homeowners.
The Perfect Choice for Montréal's Climate Extremes
With Montreal’s unpredictable weather swings, a reliable heating and cooling solution is essential. The SHARP ZU1 Mini Split Heat Pump stands out for its cooling capacity of 24,000 BTU and a heating range that goes down to -27°C, making it ideal for our cold Canadian winters and humid summers. This specific unit is eligible for Hydro-Québec’s highest LogisVert Grant, amounting to a generous $2,688—a testament to its energy efficiency and eco-conscious design.
Key Features That Make the SHARP ZU1 Exceptional
-
Advanced Plasmacluster Technology: Known for its ability to purify the air, this system generates positive and negative ions, which neutralize airborne contaminants, allergens, and even viruses. This feature ensures a healthier indoor environment, perfect for households prioritizing air quality.
-
High Efficiency and Quiet Operation: With an energy efficiency rating of 22.0 SEER, the SHARP ZU1 is one of the most efficient models on the market, helping homeowners cut down on energy bills while minimizing environmental impact. Its sound pressure levels are remarkably low—53 dB(A) for the exterior and a variable range of 25 to 49 dB(A) inside—ensuring a quiet, serene environment without the typical hum of older HVAC units.
-
Smart, WiFi-Enabled Control: Homeowners can control this system remotely, thanks to the built-in WiFi. Adjusting the temperature from anywhere in the house or even outside is a breeze, adding convenience and flexibility to everyday life.
-
Durable Design with R-32 Refrigerant: The SHARP ZU1 uses R-32 refrigerant, known for its lower environmental impact compared to traditional options. Additionally, the unit’s exterior is engineered to withstand extreme conditions, from harsh sunlight to icy weather.
Installation Specifics – Crafting the Perfect Setup
For this installation, we carefully selected a rooftop location to optimize airflow and reduce noise impact. By mounting the exterior unit securely, we ensured its stability and optimal performance, even in high winds or snowy conditions. Wooden beams were used as a base for added support, preventing vibrations from disturbing the building’s structure. This installation’s configuration not only prioritizes efficiency but also makes future maintenance easy, a feature that is particularly appreciated by our customers in Montréal-Nord.
Why the SHARP ZU1 Is a Smart Investment
With its 10-year warranty covering compressor, parts, and labor, the SHARP ZU1 promises reliability and peace of mind for years to come. It’s a system designed for the long haul, offering energy savings and robust performance even in the most frigid winter months. Plus, with the LogisVert Grant incentive, customers can recoup a portion of their investment, making this installation not only a comfort upgrade but a financially sound choice as well.

Eco-Friendly Performance with R-32 Refrigerant
As a responsible HVAC provider, we’re proud to install systems that are environmentally friendly. The SHARP ZU1 uses R-32 refrigerant, which has a lower global warming potential (GWP) compared to other common refrigerants like R-410A. This helps homeowners reduce their carbon footprint while enjoying a high-performance system that meets today’s energy standards.
Unparalleled Comfort with the Coanda Airflow Effect
One of the unique selling points of the SHARP ZU1 is its Coanda Airflow technology, which directs airflow along the ceiling, allowing even distribution of warm or cool air without direct exposure. This enhances comfort by eliminating cold drafts and hot spots, providing a more consistent indoor climate.
Customer Satisfaction and Aftercare
At AirGreen, customer satisfaction is our top priority. After completing the installation, we conducted a thorough system check, ensuring that every component was functioning perfectly. We also provided the homeowner with detailed instructions on using the WiFi controls, setting energy-saving modes, and scheduling maintenance checks. Our goal is to make HVAC ownership as easy and worry-free as possible.

What would it look like 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.

Your own project, step by step
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.
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.
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.
