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.
At AirGreen, we take pride in delivering top-notch HVAC services to our valued customers in Montréal, Laval, Longueuil, as well as the North and South Shores. Our latest project was an installation of a Sharp ZHU1 12,000 BTU wall-mounted air conditioner on the North Shore. This installation exemplifies our commitment to energy efficiency, environmental responsibility, and state-of-the-art technology.
An Installation Tailored to Efficiency and Comfort
At the heart of this installation lies a Sharp ZHU1 12,000 BTU wall-mounted air conditioner, an Energy Star®-certified unit that combines high performance with eco-friendliness. Designed to deliver reliable cooling and heating, this system provides optimal comfort even in Québec's harsh winters and humid summers.
One of the key aspects of this installation is the LogisVert grant of $2268 from Hydro-Québec, making it an excellent choice for energy-conscious homeowners looking to make smart investments in their HVAC systems. Thanks to its energy efficiency, the Sharp ZHU1 qualifies for these significant rebates, which help reduce upfront costs and offer long-term savings on energy bills.
Why Choose the Sharp ZHU1?
The Sharp ZHU1 stands out for its advanced features and superior performance, making it an ideal solution for homes in Québec's fluctuating climate. Here are some of the key highlights of this model:
- Cooling Capacity: 12,000 BTU
- Heating Capacity: Effective down to -27°C, perfect for Québec winters.
- Energy Efficiency: A stellar 25.0 SEER rating ensures lower energy consumption and reduced utility bills.
- Noise Level: Extremely quiet, with sound pressure levels of 49.0 dB(A) outdoors and as low as 22 dB(A) indoors.
- Refrigerant: R-32 refrigerant, known for its lower global warming potential compared to older refrigerants like R-22, further enhancing the system's eco-friendliness.
Advanced Technology for Ultimate Comfort
One of the things that sets the Sharp ZHU1 apart is its cutting-edge technology designed to optimize airflow, energy usage, and air quality. This installation featured several key innovations that elevate the performance and comfort of the system:
Nature Wing Fan Blades for Superior Air Circulation
The Sharp ZHU1 incorporates Nature Wing fan blades inspired by natural forms, like the wings of a dragonfly, to enhance airflow efficiency. This design increases air circulation by approximately 30%, ensuring that your space is evenly cooled or heated with less energy usage. These fan blades are used in both the indoor and outdoor units, maximizing comfort throughout the entire home.
Plasmacluster Ion Technology: Cleaner, Healthier Air
For families looking to improve indoor air quality, the Sharp ZHU1 offers Plasmacluster Ion Technology. This system releases both positive and negative ions that neutralize airborne viruses, bacteria, mold, and allergens, keeping your home's air clean and fresh. Whether you're dealing with dust, pet dander, or seasonal allergens, the Plasmacluster system helps to remove harmful particles and improve overall air quality.
This air purification system also combats unpleasant odors, ensuring a more pleasant living environment.
Coanda Effect for Even Temperature Distribution
Another standout feature of the Sharp ZHU1 is the Coanda airflow effect. By mimicking the natural movement of air, the system directs airflow along the ceilings and walls, creating a more even distribution of warm or cool air throughout your home. This technology prevents hot and cold spots, ensuring that every corner of your room maintains a consistent temperature.
Built-in WiFi Connectivity for Smart Control
The Sharp ZHU1 also comes equipped with WiFi connectivity, giving homeowners complete control over their system via a smartphone app. Whether you're at home or away, you can easily adjust the temperature, monitor energy consumption, or receive alerts about system performance.
The app also provides detailed real-time data on energy usage, allowing you to make informed decisions and reduce your overall energy footprint. You can track monthly and daily energy consumption, giving you a clearer picture of your usage patterns and how to optimize them.
Quiet Operation for Undisturbed Comfort
This Sharp unit operates at extremely low noise levels, making it perfect for bedrooms, home offices, or any other area where silence is golden. With indoor sound levels as low as 22 dB(A), the system works quietly in the background, so you can go about your day without disruption.
Built to Last with Superior Warranties
At AirGreen, we believe in providing our customers with reliable and long-lasting HVAC solutions. The Sharp ZHU1 is backed by an impressive 10-10-10 warranty, covering compressor, parts, and labor for 10 years. This ensures peace of mind for homeowners, knowing that their investment is protected for the long haul.
For added protection, we offer an additional 10-10-10 extended warranty, ensuring that every component of the system remains covered for up to 20 years of total protection. This level of warranty coverage is unmatched in the HVAC industry and demonstrates our commitment to quality service and customer satisfaction.
Installation Details: A Seamless Process
Our experienced technicians at AirGreen ensure that every installation is smooth, efficient, and up to code. For this North Shore installation, we placed the outdoor unit securely on a raised metal platform, protecting it from snow and debris during the harsh Québec winters. The tubing used was 1/4 - 3/8, and the system operates on 220V, ensuring maximum efficiency.
The placement of the indoor unit was carefully chosen to optimize airflow and maintain an even temperature throughout the living space. By combining the Coanda effect and Nature Wing fan blades, we ensured that the entire area would benefit from the Sharp ZHU1's powerful yet energy-efficient performance.
Eco-Friendly and Energy Conscious
One of the main reasons why we recommend the Sharp ZHU1 is its focus on sustainability. The unit utilizes R-32 refrigerant, which not only reduces greenhouse gas emissions but also improves the system's overall efficiency by 10% compared to older models. This makes it a perfect choice for environmentally-conscious homeowners looking to reduce their carbon footprint.
Additionally, thanks to its Energy Star Cold Climate® certification, the Sharp ZHU1 can operate efficiently even in the coldest of winters, reducing energy consumption while maintaining a warm, comfortable indoor environment. This is especially important for homes in Québec, where winter temperatures can plummet well below zero.

And 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.
