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.
The Perfect Solution for Year-Round Comfort
At AirGreen, we pride ourselves on providing top-notch HVAC installations across Montreal, Laval, Longueuil, North Shore, and South Shore. Recently, we completed an exciting project in the scenic neighborhood of Rivière-des-Prairies–Pointe-aux-Trembles. Our client required an efficient, eco-friendly solution to keep their home comfortable throughout the year, and we knew exactly what they needed: the Sharp ZU1 Mini Split. This 15,000 BTU system offers unbeatable performance in both heating and cooling, with advanced features that enhance energy efficiency and comfort.
Why Choose the Sharp ZU1?
The Sharp ZU1 Mini Split stands out for several reasons. Not only does it meet the highest standards for energy efficiency, but it’s also designed to handle extreme climates—making it a perfect choice for Quebec’s unpredictable weather. The model we installed comes with a cooling capacity of 15,000 BTU and a heating capacity down to -27°C, ensuring year-round comfort no matter the season.
Let’s take a closer look at why this particular installation was so special.
The Challenge: Providing Comfort in Extreme Conditions
Living in Montreal means dealing with frigid winters and hot summers, and our client needed a system that could perform well in both extremes. The Sharp ZU1, with its ability to function even at -27°C, was a clear winner. This heat pump doesn’t just heat and cool—it also purifies the air, thanks to Sharp's exclusive Plasmacluster technology, which neutralizes airborne contaminants, making the air inside the home cleaner and healthier.
Moreover, the ZU1 series is one of the first to use the new R-32 refrigerant, which is more environmentally friendly and energy-efficient. By opting for this system, our client not only benefits from better performance but also takes an active step toward reducing their carbon footprint.
The Installation Process: A Seamless Integration
The installation in Rivière-des-Prairies–Pointe-aux-Trembles required a few key steps to ensure everything was set up perfectly. Our team worked efficiently to mount the outdoor unit to the brick exterior, ensuring it was securely fastened and positioned for optimal airflow. With dimensions of 30.72 x 10.59 x 21.25 inches for the exterior unit, we carefully chose the placement to minimize visibility while maintaining easy access for maintenance.
Inside the home, the indoor unit (measuring 41.42 x 9.80 x 12.44 inches) was mounted in a central location to provide maximum airflow throughout the house. The Coanda airflow control feature of the Sharp ZU1 directs air along the walls and ceiling, ensuring even temperature distribution without blowing directly on occupants—a huge plus for those looking to avoid drafts.
Unique Features of the Sharp ZU1 Mini Split
What makes this system stand out is its combination of cutting-edge technologies, designed to improve comfort and efficiency:
-
Plasmacluster Technology: This unique feature sets Sharp apart from other brands. It works by releasing ions that neutralize allergens, mold, and even viruses in the air. In fact, it’s one of the few systems on the market that actively purifies indoor air while heating and cooling.
-
Coanda Airflow Control: Sharp's ZU1 system uses natural airflow tendencies to distribute air more evenly. Instead of feeling cold air blowing directly on you, the system guides airflow across the ceiling and walls, ensuring a uniform temperature throughout the room.
-
Energy Star® Certified: Not only is the Sharp ZU1 environmentally friendly thanks to the use of R-32 refrigerant, but it also comes with Energy Star® certification for its outstanding efficiency.
-
Super Quiet Operation: The indoor unit operates at a whisper-quiet 23-46 dB(A), making it ideal for bedrooms, living rooms, or any space where noise levels need to be kept low.
Grants and Rebates: Saving You Money
One of the best parts about this installation? The LogisVert grant from Hydro-Québec. Thanks to the energy efficiency of the Sharp ZU1, this model qualifies for a $2,172 provincial grant, reducing the overall cost of the system for our client. Combined with the potential for federal grants of up to $5,000, the total savings are significant—making the Sharp ZU1 not only a great choice for comfort but also for your wallet.
Built to Last: Durability and Warranty
At AirGreen, we believe in providing systems that offer both performance and reliability. The Sharp ZU1 comes with a comprehensive 10-year warranty on the compressor, parts, and labor, giving our client peace of mind knowing that their investment is protected for the long term. With the anticorrosive coating on the outdoor unit and the multiple drainage holes to prevent freezing, this system is built to withstand Quebec’s harsh winters and humid summers.
The Future of HVAC: Smart Connectivity
In addition to its powerful performance, the Sharp ZU1 also offers modern conveniences like Wi-Fi connectivity. The system can be controlled remotely via a smartphone app, allowing homeowners to adjust the temperature and monitor energy usage from anywhere. This smart connectivity feature ensures that energy is not wasted when no one is home, helping our client save on their energy bills while staying comfortable.

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.
