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.
Efficient Comfort Meets Elegant Innovation in Outremont
At AirGreen, we recently had the privilege of installing the state-of-the-art SHARP ZHU1 12,000 BTU ductless heat pump in a charming Outremont home. This project showcases not only the technical precision of our team but also the unparalleled features of the SHARP ZHU1, a product that seamlessly blends efficiency, innovation, and sustainability. Let’s delve into the details of this unique installation and the outstanding benefits it brings to our customers.
The Setting: A Warm Welcome in Outremont
Nestled in the heart of Outremont, this installation was all about enhancing the comfort and air quality of a beautiful residence. Outremont's blend of historic charm and modern living calls for HVAC solutions that are both efficient and aesthetically pleasing. Our customer sought a heat pump that could tackle Quebec’s extreme winters and sweltering summers while offering sleek, unobtrusive design. The SHARP ZHU1 was the perfect match for these requirements.
Why the SHARP ZHU1 Stands Out
Impressive Heating and Cooling Capabilities
The SHARP ZHU1 is a top performer, offering 12,000 BTUs of cooling power and an ability to heat even when outdoor temperatures plummet to an icy -27°C. This makes it ideal for Montreal’s unpredictable climate. Unlike many competitors, this heat pump maintains consistent performance in extreme cold, ensuring year-round comfort.
Unmatched Energy Efficiency
Rated at a stellar 25.0 SEER, the SHARP ZHU1 is engineered for energy-conscious homeowners. Equipped with the R-32 refrigerant, it not only reduces electricity consumption but also minimizes environmental impact. Compared to older refrigerants like R-22, R-32 has a significantly lower global warming potential, making it a sustainable choice for eco-friendly living.
Silent Operation
Peace and quiet are paramount in any home. The SHARP ZHU1 delivers whisper-quiet operation with an interior sound pressure level ranging from 22 to 44 dB(A) and an exterior level of just 49 dB(A). This ensures that the unit goes virtually unnoticed while providing maximum comfort.
Advanced Air Purification with Plasmacluster Technology
The SHARP ZHU1 doesn’t just regulate temperature; it also purifies the air with its Plasmacluster ion technology. This innovative feature eliminates airborne bacteria, viruses, and allergens, creating a healthier indoor environment. Say goodbye to mold, odors, and pollutants, and hello to fresher, cleaner air.
Details of the Installation
Perfect Placement for Optimal Performance
Our team carefully selected a central location within the home to install the interior unit. Measuring 41.42 x 9.80 x 12.44 inches, the compact design of the SHARP ZHU1 allowed us to position it discreetly above a doorway. This ensured optimal airflow throughout the space without compromising the aesthetic of the room.
Efficient Outdoor Installation
The exterior unit, measuring 30.72 x 10.59 x 21.25 inches, was mounted securely to withstand the elements while ensuring minimal visual impact. The anti-corrosive coating on the outdoor unit guarantees long-lasting performance, even in Quebec’s harsh winters.
Seamless Integration
To ensure efficiency and longevity, we used high-quality 1/4 - 3/8 inch piping and connected the system to a 220V power supply. The 10-10-10 warranty (10 years on the compressor, parts, and labor) provides peace of mind, demonstrating the reliability of this cutting-edge product.
Grant Eligibility: A Game-Changer for Homeowners
One of the most exciting aspects of this installation is its eligibility for the $2,268 LogisVert Grant by Hydro-Québec—the highest amount offered for a 12,000 BTU heat pump! This grant makes the SHARP ZHU1 not only a smart investment in comfort but also a financially savvy choice for homeowners looking to upgrade their HVAC systems.
Unique Features That Set the SHARP ZHU1 Apart
Nature-Inspired Fan Design
The ZHU1 features fan blades inspired by dragonfly wings and bird flight patterns, optimizing airflow by up to 30% indoors and 20% outdoors. This innovative design enhances efficiency while reducing energy consumption.
Coanda Airflow Control
Thanks to the Coanda effect, this unit directs air strategically along walls and ceilings to ensure even temperature distribution. This eliminates uncomfortable drafts and ensures a consistent climate throughout the home.
Smart Connectivity
With built-in WiFi, the SHARP ZHU1 offers complete control via a smartphone app. Features include:
- Real-time monitoring of temperature and humidity
- Energy consumption tracking
- Multi-zone control for additional indoor units
- GPS interlocking to adjust settings based on your location
Quick Defrost Technology
Defrost cycles are 60% faster, ensuring uninterrupted heating during Quebec’s coldest months. The patented Hot Gas Pipe technology further enhances reliability by preventing ice buildup in the outdoor unit.
The Customer Experience
Our client was thrilled with the results, particularly the unit’s sleek design and ultra-quiet operation. They were also impressed by the air purification capabilities, which significantly improved the indoor air quality. Knowing that the system could handle even the harshest winters gave them confidence in their investment.

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.
