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 Reliable Heating and Cooling Solution for Quebec’s Extreme Climate
At AirGreen, we understand how vital it is to have a high-performing HVAC system that you can trust, especially when you're facing the fluctuating and often harsh weather conditions of Quebec. In our latest installation on the North Shore, we provided a comprehensive heating and cooling solution for a homeowner using the Sharp ZU1 Wall-Mounted Heat Pump. This advanced 18,000 BTU unit is not only a testament to the sharp technological advancements in energy efficiency but also ensures the ultimate comfort for homes, even in temperatures as low as -27°C. The unit is eligible for a $2,640 LogisVert Grant by Hydro-Québec, making it a smart, energy-efficient choice for homes across Montreal, Laval, and the South Shore.
Sharp ZU1: Where Performance Meets Innovation
This 18,000 BTU Sharp ZU1 Wall-Mounted Heat Pump installation has quickly become one of the most popular choices for our clients in the North Shore. The homeowner wanted a system that would maintain a comfortable indoor climate year-round while reducing their environmental impact. The Sharp ZU1 fits the bill perfectly, being the first in the market to use the R-32 refrigerant, a more energy-efficient and environmentally friendly option that aligns with Quebec’s growing green initiatives.
But what really makes this unit stand out? It's a combination of advanced features and sharp technology designed to adapt to even the most demanding conditions.
Superior Technology for Unmatched Comfort
The Sharp ZU1 isn’t just another heat pump—it's a revolutionary system designed with Plasmacluster technology, which provides superior air purification. Unlike traditional systems that simply heat or cool a room, the Sharp ZU1 goes the extra mile by neutralizing airborne bacteria, viruses, mold, and allergens. This ensures not only comfort but also a healthier indoor environment.
Key Features of the Sharp ZU1 Heat Pump:
- Cooling Capacity: 18,000 BTU, enough to cool down large spaces effectively.
- Heating Capacity: Operates efficiently down to -27°C, perfect for Quebec winters.
- Plasmacluster Technology: Ensures superior air quality by eliminating airborne viruses, allergens, and mold.
- Coanda Airflow Control: Distributes air evenly throughout the room, ensuring uniform temperature without direct drafts.
- Energy Star Certified: Recognized for its energy-saving capabilities, ensuring lower utility bills.
- WiFi Connectivity: Allows for seamless remote control of your home’s climate via a smartphone app.
- Quiet Operation: The Sharp ZU1 maintains a low sound pressure level of 25 dB(A) indoors, making it quieter than a standard conversation.
Installation Details: Expert Workmanship in Every Corner
At AirGreen, we take pride in delivering not only top-of-the-line products but also unmatched craftsmanship. For this installation, we focused on both functionality and aesthetics. The 18,000 BTU Sharp ZU1 Heat Pump was installed on a custom-made platform to ensure optimal airflow and performance. The outdoor unit (Serial Number: AE-X18ZU1) was carefully positioned to prevent exposure to extreme elements, while the indoor unit (Serial Number: AY-XP18ZU1) was strategically mounted to ensure an even distribution of air throughout the house.
The system’s Coanda airflow control ensures that no cold or hot drafts disrupt the comfort of the occupants, providing an even and gentle temperature regulation across all rooms.
Dimensions and Specifications:
- Interior Unit Dimensions: 41.42 x 9.80 x 12.44 inches
- Exterior Unit Dimensions: 33.47 x 13 x 27.94 inches
- Voltage: 220V
- Pipes: 1/4 - 3/8
Why This Installation Stands Out
This installation on the North Shore wasn’t just about adding another heat pump—it was about giving the homeowner a system that truly complements their lifestyle. The Sharp ZU1 offers the convenience of modern connectivity, allowing the homeowner to control the unit remotely using WiFi. Whether they’re at work or on vacation, they can monitor and adjust the temperature of their home in real-time, thanks to the Smartphone App. The app even keeps track of energy consumption, allowing users to see how much energy their system is using daily or monthly.
Additionally, this Sharp ZU1 heat pump installation was specifically designed to handle Quebec’s notorious winters. SHARP’s patented Hot Gas Pipe system ensures the outdoor compressor doesn’t freeze, even when temperatures plummet to -27°C. This unique system helps circulate residual heat through the pipes, preventing ice buildup and ensuring that the unit continues running efficiently even in the harshest weather.
Environmentally Friendly and Cost-Effective
One of the key concerns for many homeowners is finding a balance between comfort, cost, and environmental impact. With the Sharp ZU1, that balance is easily achieved. The R-32 refrigerant used in this unit reduces greenhouse gas emissions and lowers electricity consumption by about 10%, compared to traditional refrigerants. This makes the Sharp ZU1 not only a more sustainable option but also a more economical one in the long run.
Moreover, the unit’s high SEER rating of 24.0 means it operates at peak efficiency, ensuring that homeowners save on their energy bills while reducing their carbon footprint.
A Warranty You Can Trust
At AirGreen, we stand behind every product we install. The Sharp ZU1 comes with a robust 10-year warranty on the compressor, parts, and labor. This extended warranty gives homeowners peace of mind, knowing that their investment is protected for years to come.
Sound Levels You Won’t Notice
- Exterior Sound Pressure Level: 52.0 dB(A)
- Interior Sound Pressure Level: 25/49 dB(A)
The system is designed to operate quietly, ensuring that the unit won’t disrupt daily life or sleep, even when running at full capacity. This is especially important for homes in quieter, residential areas like the North Shore, where maintaining peace and quiet is just as important as maintaining the right temperature.

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.
