Bringing Comfort and Energy Efficiency to Boisbriand: A Story of Superior HVAC Installation
At AirGreen, we pride ourselves on delivering high-quality HVAC solutions tailored to the unique needs of our clients. Recently, we completed an installation of the SHARP ZU1 Mini Split Heat Pump in a charming Boisbriand residence, and we are excited to share the details of this efficient and eco-friendly project. With Boisbriand's varied climate, selecting the right system is crucial, and the SHARP ZU1 turned out to be the perfect fit.
The Machine: Precision Engineering for Harsh Winters and Hot Summers
The SHARP ZU1 Mini Split Heat Pump is a remarkable blend of technology and durability. This 18,000 BTU unit stands out for several reasons:
- Exceptional Efficiency: Operating at an impressive 24.0 SEER, this unit is designed to maximize energy savings, making it one of the most efficient options on the market.
- Extreme Cold Heating Capacity: With the ability to heat effectively at temperatures as low as -27°C, the ZU1 ensures that even the coldest Boisbriand winters won’t stand in the way of a warm and comfortable home.
- Silent Operation: Both interior and exterior units operate quietly, with sound pressure levels ranging from 25 dB(A) indoors to 52 dB(A) outdoors, providing peace and comfort without disturbing daily activities.
Why the SHARP ZU1? Maximizing Grants and Long-Term Savings
This installation isn't just about comfort; it's a smart investment. The SHARP ZU1 Mini Split Heat Pump qualifies for the highest LogisVert grant offered by Hydro-Québec for any 18,000 BTU heat pump, amounting to $2,640. This makes it a wise choice for homeowners who want to leverage available incentives while minimizing their environmental footprint.
Installation Highlights: Making the Most of Every Detail
Our team meticulously planned this project to ensure optimal performance and aesthetics. Here’s a look at the main steps we took:
- Customized Placement: We selected a strategic location for the outdoor unit, ensuring that it received adequate airflow and was protected from potential debris. Mounted securely on durable, weather-resistant brackets, it is shielded from environmental hazards while maintaining easy access for future maintenance.
- Precise Piping and Insulation: Using top-quality piping and insulation materials, we connected the indoor and outdoor units seamlessly. The pipes, sized at 1/4” and 3/8”, were carefully insulated to enhance efficiency and prevent any energy loss.
- Interior Aesthetics: The indoor unit, with its sleek design and dimensions of 41.42 x 9.80 x 12.44 inches, was installed to blend perfectly with the interior decor. Its minimalist yet sophisticated look adds a modern touch to the living space.
The Technology Behind the Comfort: Plasmacluster Ion and Smart Control
One of the standout features of the SHARP ZU1 is its Plasmacluster Ion Technology, which goes beyond just cooling or heating. This unique technology purifies the air by releasing ions that neutralize bacteria, viruses, and odors. For families in Boisbriand, this means cleaner and healthier indoor air, which is particularly valuable during the flu season.
Additionally, the unit comes equipped with built-in Wi-Fi, allowing homeowners to control the heat pump remotely. Imagine being able to adjust your home’s temperature from your smartphone while you’re at work or on vacation—convenience and comfort, all at your fingertips.
Challenges and Solutions: Overcoming the Installation Obstacles
Every installation has its challenges, and this one was no exception. The home in Boisbriand presented some unique hurdles:
- Space Constraints: The exterior unit needed to be installed on a small balcony, which limited our options. Our team expertly measured and adjusted the mounting height to ensure stability and compliance with local codes.
- Noise Management: Considering the proximity to neighboring homes, we prioritized sound reduction by using vibration dampeners and carefully positioning the unit away from high-traffic areas.
Long-Term Benefits: Why This System Is a Game-Changer
Investing in a SHARP ZU1 Mini Split Heat Pump means more than just comfort; it’s a long-term solution that pays for itself over time. Here’s what makes it a standout choice:
- Reduced Energy Bills: With its high SEER rating and intelligent inverter technology, the ZU1 significantly lowers energy consumption compared to traditional systems.
- Enhanced Home Value: An efficient HVAC system is a strong selling point, adding value to the property and appealing to eco-conscious buyers.
- Comprehensive Warranty: The SHARP ZU1 comes with a robust 10-year warranty on the compressor, parts, and labor, providing homeowners with peace of mind for years to come.
Eco-Friendly Refrigerant: R-32 for a Greener Future
We are committed to sustainability, and the SHARP ZU1 aligns perfectly with our values. This unit uses R-32 refrigerant, which has a lower global warming potential (GWP) than traditional refrigerants like R-410A. By choosing this model, homeowners are contributing to a greener future while enjoying superior performance.

The job tools
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.

What we check on a job like this one
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.
Generic illustration of this type of installation, not a survey of this job site. Tap a number.
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.
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.
Good habits, once the unit is in place
Six simple habits that keep the unit going. Your list stays on this device.
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.
The right pages, at the right time
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.
