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.
Bringing Cutting-Edge Comfort to a Modern Quebec Home
When it comes to creating a cozy and energy-efficient home, AirGreen stands as a trusted leader in HVAC solutions. Recently, we had the privilege of installing the state-of-the-art SHARP ZHU1 12,000 BTU Mini Split Heat Pump in a residence located in the charming city of Saint-Constant. This installation not only highlights our expertise but also showcases the remarkable features of the SHARP ZHU1, one of the most advanced systems available for Quebec’s climate.
Why the SHARP ZHU1 Mini Split Stands Out
This isn’t just another heat pump—it’s a true innovation designed for Quebec’s extreme winters and warm summers. Here’s what makes it extraordinary:
- Cooling Capacity: 12,000 BTU, perfect for maintaining comfort in medium-sized spaces.
- Heating Capacity: Efficiently warms spaces even at frigid temperatures as low as -27°C.
- Energy Efficiency: Boasts an impressive 25.0 SEER rating, making it one of the most efficient units on the market.
- Eco-Friendly Refrigerant: Uses R-32 refrigerant, which reduces greenhouse gas emissions and improves energy consumption by 10% compared to traditional refrigerants.
A Grant-Worthy Investment
The SHARP ZHU1 is eligible for the $2,268 LogisVert grant by Hydro-Québec, the highest grant available for a 12,000 BTU system in the province. This incentive makes it an excellent choice for environmentally conscious homeowners looking to save on their energy bills.
A Unique Installation Story
Every installation tells a story, and this one is no exception. The Saint-Constant homeowner was seeking a solution that combined high performance with sleek design. After assessing their needs, the SHARP ZHU1 emerged as the perfect match, offering unmatched energy efficiency and whisper-quiet operation.
Step 1: Assessing the Space
We began by evaluating the layout and insulation of the home to determine the optimal placement of the indoor and outdoor units. The goal was to ensure maximum airflow while maintaining the unit's aesthetic appeal.
Step 2: Precision Installation
Our technicians carefully mounted the indoor unit in the living room, where it blends seamlessly with the modern decor. The compact dimensions of the unit (41.42" x 9.80" x 12.44") make it unobtrusive while still delivering powerful performance. The outdoor unit, equally compact and durable, was strategically installed to minimize exposure to the elements and maintain optimal performance.
Step 3: Seamless Integration
The system’s built-in Wi-Fi capability was a game-changer for the homeowner. With the SHARP app, they can now control the unit remotely, monitor energy usage, and adjust settings for ultimate comfort—all from their smartphone.
Advanced Features That Redefine Comfort
Quiet Operation
With a sound level as low as 22 dB(A) for the indoor unit, the SHARP ZHU1 operates so quietly that you’ll forget it’s even there. The outdoor unit is equally impressive, with a noise level of just 49 dB(A).
Plasmacluster Air Purification
The SHARP ZHU1 goes beyond temperature control. Its Plasmacluster technology eliminates airborne viruses, bacteria, mold, and allergens, ensuring the air inside your home is as clean as it is comfortable.
Nature-Inspired Fan Blades
Drawing inspiration from the aerodynamics of eagle wings and albatross feathers, the fan blades improve airflow by 30%, making the unit both efficient and environmentally friendly.
Coanda Airflow Technology
This feature ensures that air circulates evenly throughout the room by directing it along walls and ceilings. Say goodbye to hot and cold spots—this unit delivers uniform comfort.

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.
