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 Efficiency to Lachine: A Sharp ZHU Installation Story
At AirGreen, we take pride in providing efficient, reliable, and environmentally responsible heating and cooling solutions across Montreal, Laval, Longueuil, and the North and South Shores. Our recent installation of a Sharp ZHU 12,000 BTU wall-mounted heat pump in Lachine, Montreal, exemplifies our commitment to delivering superior HVAC services. The Sharp ZHU, equipped with advanced features such as Plasmacluster air purification, R-32 refrigerant, and impressive heating capabilities down to -27°C, offers homeowners the perfect balance between comfort and energy efficiency.
A Heat Pump Tailored for Quebec Winters
Quebec’s extreme climate can be unforgiving, especially during the long winter months. That's why the Sharp ZHU series is an excellent choice for homes in this region. With the ability to provide heating even when temperatures plummet to -27°C, the ZHU ensures that our clients stay warm and comfortable without the need for supplementary heating sources. This particular unit, with 12,000 BTUs of heating and cooling power, is perfectly sized for smaller homes or specific rooms, offering optimal climate control year-round.
The R-32 refrigerant used in this model is not only energy-efficient but also environmentally friendly, contributing to lower greenhouse gas emissions and reducing the overall energy footprint. AirGreen is proud to offer systems like the ZHU that meet modern environmental standards while maximizing energy efficiency for homeowners.
Efficient and Quiet Operation
One of the standout features of the Sharp ZHU 12,000 BTU unit is its exceptionally low sound pressure level. With only 22 to 44 dB(A) indoors and 49 dB(A) outdoors, this heat pump operates quietly, allowing homeowners to enjoy peace and comfort without the disruptive noise typically associated with HVAC systems. This makes it an ideal solution for bedrooms, living spaces, or any area where tranquility is essential.
The installation in Lachine was smooth and efficient, taking full advantage of the compact design of the ZHU series. The indoor unit measures 41.42 x 9.80 x 12.44 inches, while the outdoor unit is slightly larger at 30.72 x 10.59 x 21.25 inches. Its sleek profile ensures it fits seamlessly into the home environment without occupying too much space, whether mounted on a rooftop, as in this installation, or on an exterior wall.
Maximizing Energy Savings with Grants and Rebates
This Sharp ZHU installation in Lachine is not only about providing comfort and reliability; it also brings significant financial benefits to the homeowner. The LogisVert Grant by Hydro-Québec provides an impressive $2,268 rebate for this model, making it the highest grant available for any 12,000 BTU mini-split heat pump. Combined with federal and provincial grants that can total up to $5,000, homeowners can significantly reduce the upfront cost of their HVAC system while also enjoying long-term energy savings.
With a SEER rating of 25.0, the Sharp ZHU is among the most energy-efficient models on the market today. This high efficiency ensures that the system consumes less electricity, translating to lower utility bills—something every homeowner can appreciate, especially during Quebec’s intense winter heating season.
Advanced Technology for Superior Indoor Air Quality
What truly sets the Sharp ZHU apart from other models is its incorporation of Plasmacluster technology, a patented air purification system unique to Sharp products. This technology actively works to remove airborne viruses, mold, bacteria, and allergens from the indoor air, ensuring a healthier living environment for the occupants. The Plasmacluster ions mimic those found in nature, neutralizing harmful particles and improving air quality in ways that standard heat pumps cannot.
For the homeowner in Lachine, this added benefit means more than just temperature control—it also means better air quality, reduced allergens, and a cleaner, healthier home environment for the whole family.
Cutting-Edge Design: Nature-Inspired Fan Blades
In our installation, both the indoor and outdoor units of the Sharp ZHU utilize nature-inspired fan blades for enhanced airflow. The indoor unit features blades designed like dragonfly wings, which increase airflow by approximately 30% compared to traditional designs. Meanwhile, the outdoor unit incorporates blades shaped after the wings of eagles and albatrosses, offering improved airflow with minimal energy consumption.
These fan blade innovations ensure that the Sharp ZHU operates more efficiently, using less power to move air through the system while delivering superior performance. This not only enhances the overall comfort within the home but also contributes to the system's exceptional energy efficiency.
Smart Connectivity and User Control
The Sharp ZHU is equipped with WiFi connectivity, allowing homeowners to control their heat pump from their smartphone. Through the app, users can monitor the temperature and humidity in real time, adjust settings remotely, and even receive notifications if the system detects no movement in the home for an extended period, optimizing energy usage. This level of control ensures that the system is only running when needed, helping to further reduce energy waste.
Additionally, the ZHU series features a multi-zone option, enabling homeowners to manage multiple indoor units from a single control panel or smartphone. Whether cooling a single room or maintaining consistent temperatures throughout the entire house, the Sharp ZHU offers unparalleled flexibility and convenience.
Environmentally Friendly and Durable
At AirGreen, we always prioritize sustainability. The Sharp ZHU uses R-32 refrigerant, which has a lower global warming potential than older refrigerants like R-22. This makes it an excellent choice for environmentally conscious homeowners who want to reduce their carbon footprint without sacrificing performance.
Moreover, the ZHU series is built to last, with anti-corrosive coatings applied to the outdoor compressor to protect against harsh weather conditions. This ensures the unit remains reliable for years to come, even in Quebec’s extreme climates. The 10-year warranty on the compressor, parts, and labor, along with an optional extended warranty, gives homeowners added peace of mind that their investment is protected.

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.

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.
