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.

This allows the system to provide high-level performance even in extreme cold, making it an ideal choice for Montréal’s harsh winters.
Nature Wing Fan Blades
Sharp takes inspiration from nature in designing their products, and the ZHU1 is no exception. The Nature Wing fan blades, found in both the indoor and outdoor units, are designed to mimic the wings of eagles and albatrosses, enhancing air circulation by up to 30% while reducing the amount of energy needed to move air through the system. This advanced design helps create a more comfortable living environment by improving air distribution and maintaining uniform temperature levels throughout the home.
Installation Details – LaSalle, Montréal
The installation of the Sharp ZHU1 12,000 BTU heat pump in LaSalle was completed with precision and care, ensuring both efficiency and aesthetic appeal. Our team mounted the outdoor unit under a metal staircase, using specialized brackets to keep it securely elevated and protected from potential hazards. The indoor unit, with its sleek design and quiet operation, was installed to blend seamlessly into the home’s interior.
The Sharp ZHU1 system is also equipped with Plasmacluster technology, which purifies the air by neutralizing airborne bacteria, viruses, and allergens. This makes it an excellent choice for households with family members who suffer from allergies or respiratory issues.
Benefits of the LogisVert Grant
One of the key advantages of installing the Sharp ZHU1 is its eligibility for the LogisVert Grant by Hydro-Québec, which offers a rebate of up to $2,268. This grant makes it easier for homeowners to invest in energy-efficient systems that lower both environmental impact and monthly utility bills.
Quiet Operation – Comfort Without the Noise
When it comes to heating and cooling systems, one of the most important factors for many homeowners is noise level. Fortunately, the Sharp ZHU1 excels in this area. With an indoor sound level as low as 22 dB(A), it's quieter than a library. The outdoor unit, operating at 49 dB(A), is barely noticeable even when installed in close proximity to living spaces.
Smart Connectivity and Control
In today’s connected world, convenience is key, and the Sharp ZHU1 offers WiFi connectivity for real-time monitoring and control via a smartphone app. This allows homeowners to adjust the temperature remotely, ensuring the perfect indoor climate as soon as they step through the door. Additionally, the app provides insights into energy consumption, allowing users to optimize usage and reduce costs.
Environmental Responsibility – R32 Refrigerant
With the growing need for eco-friendly solutions, the Sharp ZHU1 heat pump’s use of R-32 refrigerant stands out. This refrigerant not only lowers greenhouse gas emissions but also consumes less electricity, reducing both your carbon footprint and your energy bills. Sharp’s commitment to environmental responsibility aligns perfectly with AirGreen’s mission to provide sustainable HVAC solutions to Montréal and the surrounding areas.
High-Performance Heating – Even in Extreme Cold
One of the unique selling points of the Sharp ZHU1 is its ability to function in extremely cold conditions, as low as -27°C. This makes it ideal for homeowners in Montréal, where winter temperatures frequently drop below freezing. Even when it’s frigid outside, the Sharp ZHU1 maintains an impressive heating capacity of 11,200 BTU at -27°C, ensuring warmth and comfort during the harshest months of the year.

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.
