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.
A Seamless HVAC Solution for Comfort and Efficiency
Transforming Homes in Saint-Léonard with the SHARP ZHU1 Heat Pump
At AirGreen, we pride ourselves on delivering not just installations but tailored solutions that align with our customers' needs, the environment, and advanced technology. Our recent project in Saint-Léonard showcases the installation of a 12,000 BTU SHARP ZHU1 ductless heat pump—a remarkable choice for year-round climate control. Combining state-of-the-art Japanese innovation, energy efficiency, and exceptional functionality, this system ensures comfort even in Quebec's harsh winters.
Why the SHARP ZHU1 Stands Out
The SHARP ZHU1 heat pump is no ordinary HVAC system. Designed to handle temperatures as low as -27°C, it offers unparalleled energy efficiency with a SEER rating of 25.0. Its use of the eco-friendly R-32 refrigerant not only reduces environmental impact but also optimizes energy consumption. With the inclusion of WiFi connectivity, homeowners can easily monitor and control their system remotely, ensuring ultimate convenience.
Key specifications include:
- Cooling Capacity: 12,000 BTU
- Heating Capacity: 12,000 BTU (-27°C)
- Interior Dimensions: 41.42 x 9.80 x 12.44 inches
- Exterior Dimensions: 30.72 x 10.59 x 21.25 inches
- Noise Levels: 22-44 dB(A) indoors, 49 dB(A) outdoors
- Warranty: 10 years (Compressor, Parts, and Labor)
This unit is not only Energy Star® certified but also eligible for a $2,268 LogisVert Grant by Hydro-Québec, the highest rebate available for a 12,000 BTU heat pump.
A Tailored Installation Process
Our team was thrilled to assist a homeowner in Saint-Léonard who sought an efficient and environmentally friendly heating and cooling solution. The unique placement of the property—nestled between two narrow walls—required precision and expertise. Our technicians meticulously planned the installation to ensure the outdoor unit was securely mounted while optimizing airflow and minimizing noise.
The indoor unit was positioned to maximize the Coanda airflow effect, directing air along walls and ceilings to provide even temperature distribution throughout the home. This placement not only enhanced comfort but also utilized the system's Plasmacluster technology to purify the air by eliminating airborne viruses, mold, and odors.
Advanced Features That Make a Difference
Plasmacluster Technology for Cleaner Air
One standout feature of the SHARP ZHU1 is its Plasmacluster ion technology, which mimics natural air purification processes. By releasing positive and negative ions, this system neutralizes harmful airborne particles, ensuring the air inside your home is as fresh as the outdoors.
Coanda Airflow Control
Using the Coanda effect, the SHARP ZHU1 directs air along strategic surfaces to avoid direct drafts while maintaining uniform temperature throughout the space. Whether cooling during summer or heating during winter, this feature ensures ultimate comfort.
Smart Connectivity and Energy Monitoring
With built-in WiFi, homeowners can control their system via a smartphone app. Features like real-time temperature monitoring, energy usage tracking, and motion detection optimize efficiency and convenience. Additionally, the Auto Changeover mode seamlessly switches between heating and cooling based on outdoor temperatures, making seasonal transitions effortless.
Eco-Friendly Innovation
The use of R-32 refrigerant not only reduces greenhouse gas emissions but also enhances the system's efficiency by approximately 10%. This innovative refrigerant aligns with AirGreen’s commitment to sustainability and helps homeowners reduce their carbon footprint.
Challenges Met with Expertise
The narrow alley in which the outdoor unit was installed posed a unique challenge. Our team utilized specialized mounting brackets to securely position the unit, ensuring optimal performance while maintaining the aesthetic appeal of the property. We also reinforced the piping system with anti-corrosive materials to withstand Quebec’s extreme weather conditions.
The interior unit was mounted in the central living area to provide even airflow across multiple rooms. Thanks to the Multi Space Function, the SHARP ZHU1 distributes air harmoniously across zones, ensuring consistent comfort throughout the home.

The big day, step by step
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 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.
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.
