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.
Energy-Efficient Climate Control for Extreme Winters
At AirGreen, we take great pride in ensuring that every installation meets the highest standards of efficiency and reliability. This installation in Longueuil involved a Sharp ZHU 12,000 BTU wall-mounted heat pump, designed for Quebec's harsh climate. With the ability to function in temperatures as low as -27°C, this unit ensures reliable heating during the bitterly cold winter months while also providing efficient cooling during the summer.
A Solution for Year-Round Comfort
The Sharp ZHU series represents the perfect balance between technology, performance, and environmental responsibility. The system uses the new, eco-friendly R-32 refrigerant, which not only reduces greenhouse gas emissions but also improves energy efficiency by up to 10% compared to older models using R-22. This means that the homeowner in Longueuil will not only enjoy superior comfort throughout the year but will also save on their energy bills.
Maximizing the LogisVert Grant
One of the highlights of this installation is its eligibility for a $2,268 LogisVert grant offered by Hydro-Québec. This grant is the highest available for a 12,000 BTU mini-split heat pump, making the Sharp ZHU series an incredible value. This financial incentive, combined with the unit’s Energy Star® certification, guarantees that the homeowner is making an excellent long-term investment in their home.

Cutting-Edge Design for Maximum Comfort
The Sharp ZHU heat pump doesn’t just bring efficiency; it also introduces innovative features designed for homeowner comfort. Its Plasmacluster technology stands out by actively neutralizing airborne bacteria and viruses. This purification system works to eliminate mold and other contaminants, ensuring cleaner, fresher air inside the home. Unlike other heat pumps, Sharp’s Plasmacluster offers unparalleled air quality control, perfect for families concerned about the health implications of indoor air.
Another impressive feature is the Coanda airflow control, which directs air strategically around the room to prevent uncomfortable drafts. This ensures that every corner of the space benefits from uniform temperature control. By optimizing the airflow, the Sharp ZHU creates a consistently comfortable environment, even when the heat pump is working under full load.
Eco-Friendly and Quiet Operation
For the eco-conscious homeowner, the Sharp ZHU heat pump is an ideal solution. The R-32 refrigerant not only reduces the carbon footprint but also allows the system to consume less electricity, contributing to long-term sustainability. Moreover, despite its high performance, the system operates at impressively low noise levels, making it perfect for homes where quiet operation is a priority.
The interior unit’s sound pressure is as low as 22 dB(A), ensuring that the system runs almost silently, while the exterior unit produces 49 dB(A), ensuring it doesn’t disturb the neighborhood.
Reliable Warranty and Peace of Mind
To add even more value, this Sharp ZHU installation comes with a 10-year warranty on parts, compressor, and labor. This extensive coverage offers homeowners peace of mind, knowing that their investment is protected for the long haul. AirGreen also offers an extended 10-10-10 warranty, guaranteeing optimal performance for a decade.

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.
