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 Comfort and Energy Efficiency to a Home in Terrebonne
At AirGreen, we pride ourselves on providing tailored HVAC solutions to meet the specific needs of our clients. Our recent project in Terrebonne exemplifies our commitment to excellence. This installation involved a SHARP ZHU1 Mini Split Heat Pump, a state-of-the-art system designed for Quebec's harsh winters and warm summers. With a cooling capacity of 12,000 BTU and the ability to heat efficiently even at temperatures as low as -27°C, this heat pump is an ideal solution for year-round comfort.
A Project Tailored to the Customer’s Needs
This Terrebonne homeowner sought an energy-efficient and environmentally friendly heating and cooling solution that could handle Quebec's extreme climate. After an in-depth consultation, we recommended the SHARP ZHU1 Mini Split Heat Pump, a high-performance model that checks all the boxes for energy savings, comfort, and durability.
The SHARP ZHU1 is not only an ENERGY STAR® certified unit but also eligible for the $2,268 LogisVert grant from Hydro-Québec, the highest subsidy available for a 12,000 BTU system in Quebec. This significant rebate makes it an attractive investment for homeowners looking to upgrade their HVAC systems.
Key Features of the SHARP ZHU1 Heat Pump
1. Exceptional Energy Efficiency
With an impressive 25.0 SEER rating, the SHARP ZHU1 delivers top-tier performance while consuming less electricity. Its R-32 refrigerant further enhances its energy efficiency, reducing greenhouse gas emissions and lowering utility bills by approximately 10% compared to older refrigerants.
2. Advanced Heating Capabilities
This heat pump doesn’t just keep you cool in the summer—it also provides reliable heating during Quebec's icy winters. The ZHU1 maintains 11,200 BTU/h heating capacity at -27°C, ensuring your home stays warm no matter how cold it gets outside.
3. Whisper-Quiet Operation
With an indoor noise level as low as 22 dB(A) and outdoor operation at just 49 dB(A), this system is one of the quietest on the market. Whether you’re working from home or relaxing with your family, the SHARP ZHU1 won’t disrupt your peace.
4. Plasmacluster Air Purification Technology
This exclusive SHARP technology mimics natural ionization to purify indoor air, eliminating bacteria, viruses, allergens, and odors. Not only does this system provide comfortable temperatures, but it also improves air quality, making it ideal for families with allergies or respiratory concerns.
5. Smart Connectivity
The integrated WiFi feature allows the homeowner to control the system remotely via a smartphone app. The app also tracks energy usage, ensuring the system operates as efficiently as possible.
Challenges and Solutions During Installation
Every HVAC project presents its unique challenges, and this installation was no exception. The outdoor unit needed to be mounted securely to a concrete foundation wall to prevent vibration and maximize durability. To achieve this, our team used specialized anti-vibration brackets and ensured precise leveling to enhance the system’s longevity.
The piping installation required careful routing to maintain aesthetic appeal while ensuring optimal performance. Our technicians used high-quality materials, including 1/4-inch and 3/8-inch piping for refrigerant flow, and meticulously sealed every connection to prevent leaks.
To accommodate the homeowner’s desire for discreet placement, we carefully positioned the indoor unit in a central location that maximized airflow to all areas of the home without interfering with the decor.
Why the SHARP ZHU1 is Perfect for Quebec Homes
Built for Extreme Cold
Quebec winters can be brutal, but the SHARP ZHU1 thrives in sub-zero conditions. Unlike many heat pumps that struggle below -15°C, this unit continues to provide efficient heating at temperatures as low as -27°C. For Terrebonne residents, this means reliable warmth even during the coldest months.
Eco-Friendly and Cost-Effective
The R-32 refrigerant and ENERGY STAR® certification align with Quebec’s push for greener energy solutions. By reducing power consumption and emissions, the SHARP ZHU1 not only lowers your carbon footprint but also your energy bills.
Unmatched Durability
SHARP products are known for their reliability, and the ZHU1 is no exception. With a 10-year warranty on parts, labor, and the compressor, homeowners can rest assured they’re investing in a system that will perform for years to come.
The Installation Process
Step 1: Planning and Preparation
Before the installation, we conducted a thorough assessment of the home to determine the optimal placement for both the indoor and outdoor units. Our goal was to ensure maximum efficiency and airflow while maintaining the home’s aesthetics.
Step 2: Installing the Outdoor Unit
The outdoor unit was mounted on a secure platform using anti-vibration brackets. This not only protects the system from wear and tear but also minimizes noise transfer to the home.
Step 3: Indoor Unit Installation
The sleek and compact indoor unit was installed in a living area to ensure even distribution of air throughout the home. The unit’s dimensions (41.42 x 9.80 x 12.44 inches) make it an unobtrusive yet effective addition to any space.
Step 4: Connecting and Testing
After carefully routing the piping and wiring, we connected the system and performed rigorous testing to ensure optimal performance. This included checking refrigerant levels, testing airflow, and calibrating the system for both heating and cooling modes.
Customer Satisfaction and Final Thoughts
The homeowner was thrilled with the results, praising the system’s quiet operation and advanced features. Thanks to the LogisVert grant, they were also able to offset a significant portion of the installation cost, making this project a win-win.
At AirGreen, we take pride in offering solutions that not only enhance comfort but also align with our clients’ budgets and environmental goals. The SHARP ZHU1 Mini Split Heat Pump is a testament to our dedication to providing the best HVAC systems for Quebec homeowners.

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.
