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 Integration for Unmatched Comfort
At AirGreen, we pride ourselves on providing top-notch HVAC solutions tailored to our clients' specific needs. Recently, we completed the installation of a Sharp ZU1 Mini Split Heat Pump in the beautiful area of Île-Bizard–Sainte-Geneviève, and we’re thrilled to share the story behind this project. This isn’t just any heat pump installation—it’s a remarkable transformation in home comfort that showcases the precision and reliability that Sharp brings to the table.
Project Overview
Our client reached out with a simple request: improve indoor air quality and maintain a consistent, efficient climate year-round. Given the area's cold winters and warm summers, we recommended the Sharp ZU1 Mini Split Heat Pump. Known for its efficiency and robust performance, this model boasts a cooling capacity of 18,000 BTU and a heating capacity that functions seamlessly at temperatures as low as -27°C.
Key Installation Details:
- Type: Ductless Mini Split Heat Pump
- Location: Île-Bizard–Sainte-Geneviève
- Brand: Sharp
- Model: ZU1 (Energy Star® Certified)
- Efficiency: 24.0 SEER, setting the benchmark for energy-saving capabilities
- Admissible Grant: Eligible for the highest LogisVert Grant of $2,640, making it an excellent choice for homeowners looking to maximize their investment while benefiting from eco-friendly heating and cooling.
Why We Chose the Sharp ZU1 for This Installation
The Sharp ZU1 Mini Split is not only a top-tier choice for efficiency but also a quiet champion for comfort. With an interior sound pressure level ranging from 25 to 49 dB(A), it operates so quietly that you might forget it’s there—except when you feel the perfect temperature it provides.
Advanced Technology for Modern Living
Sharp’s signature Plasmacluster Ion Technology stands out in the ZU1 model. This groundbreaking feature releases ions to purify the air, neutralizing allergens, viruses, and odors. It’s a game-changer for homes with sensitive occupants or anyone who values pristine indoor air quality.
- Cooling Mode: Distributes fresh, cool air with precision, avoiding the discomfort of direct airflow.
- Heating Performance: When temperatures plunge to -27°C, the heat pump continues to deliver consistent warmth. The advanced “Hot Gas Pipe” system ensures reliable defrosting, keeping the unit ice-free and efficient.
Installation Challenges and Solutions
No installation is without its challenges, and this project presented unique obstacles. The location’s structural layout required careful planning to ensure optimal unit placement and airflow distribution. The indoor unit, with its sleek design and compact dimensions (41.42 x 9.80 x 12.44 inches), was mounted securely to blend effortlessly into the room. The exterior unit was strategically installed to minimize exposure to harsh weather while ensuring easy access for future maintenance.
We also faced the task of routing the refrigerant lines efficiently. Using high-quality pipes of 1/4 and 3/8 inches, we secured the lines to prevent potential leaks and optimize performance. The unit’s R-32 refrigerant was another eco-conscious choice, reducing environmental impact while enhancing cooling and heating efficiency.

What Sets the Sharp ZU1 Apart?
Energy Efficiency and Cost Savings
One of the biggest advantages of the Sharp ZU1 is its inverter technology. Unlike traditional systems that power on and off, the inverter modulates the compressor speed, reducing energy consumption once the desired temperature is reached. Homeowners can enjoy a comfortable home environment while witnessing a significant reduction in their energy bills.
Whisper-Quiet Operation
Gone are the days of noisy HVAC units disrupting your peace. The Sharp ZU1’s interior sound pressure level starts at a whisper-quiet 25 dB(A), making it perfect for bedrooms, living areas, or any space where silence is golden.
Unmatched Warranty for Peace of Mind
We understand that investing in a high-quality heat pump is a big decision. That’s why the Sharp ZU1 comes with a 10-10-10 warranty: 10 years on the compressor, 10 years on parts, and 10 years on labor. This comprehensive warranty reflects the confidence we—and Sharp—have in this product's durability and performance.

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.
