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.

Why Choose the Sharp ZHU?
The Sharp ZHU series represents some of the most advanced heat pumps available today. Using the latest R-32 refrigerant, this unit reduces greenhouse gas emissions and is up to 10% more energy efficient than older models that use refrigerants like R-22. At AirGreen, we believe in offering our clients cutting-edge technology, and the ZHU model fits the bill with its commitment to sustainability and environmental responsibility.
Here are just a few features that set this model apart:
- Energy Efficiency: With a 25.0 SEER rating, this heat pump delivers incredible performance, helping to keep energy costs low.
- Plasmacluster Technology: Sharp’s unique air purification system eliminates airborne viruses, mold, and allergens, providing cleaner, healthier indoor air.
- Quiet Operation: With a sound pressure level of only 49 dB(A) outdoors and as low as 22 dB(A) indoors, this unit operates quietly, ensuring minimal disruption to the home environment.
- Wi-Fi Connectivity: This model comes equipped with Wi-Fi, allowing homeowners to control the system remotely via a smartphone app. This level of convenience ensures optimal comfort at all times.

The Installation Process: A Seamless Experience
The installation process for the Sharp ZHU 12,000 BTU heat pump involved careful planning and precision. Our team installed the outdoor unit securely under a spiral staircase, ensuring optimal airflow and easy access for maintenance. The indoor unit was mounted in a central location to allow for even air distribution throughout the home.
As always, we took great care to ensure the installation was both aesthetically pleasing and highly functional. All pipes were carefully concealed, and the system’s wiring was expertly routed to avoid any visible clutter. Our goal is to ensure that each installation not only improves the home’s comfort but also complements its appearance.
Long-Term Benefits of the Sharp ZHU Heat Pump
One of the key reasons the Sharp ZHU is such a popular choice in Montreal and its surrounding areas is its exceptional long-term benefits. In addition to the energy savings that come with its high SEER rating, the 10-10-10 warranty offers peace of mind, covering the compressor, parts, and labor for an entire decade. This level of coverage is a testament to the durability and reliability of the Sharp brand.
Moreover, the anti-corrosive coating on the compressor ensures that the outdoor unit can withstand Quebec’s extreme weather conditions, from heavy snowfall to rain and freezing temperatures. This makes it an excellent investment for homeowners looking to protect their property and reduce long-term maintenance costs.
Advanced Airflow and Comfort Control with Nature-Inspired Design
Sharp has always drawn inspiration from nature when designing its heat pumps, and the ZHU series is no exception. Both the indoor and outdoor units feature fan blades modeled after nature’s most efficient flyers, including the dragonfly, golden eagle, and albatross. These fan designs enhance airflow by up to 30% indoors and 20% outdoors, ensuring better air circulation and more efficient cooling and heating throughout the home.
Additionally, the Coanda Airflow Control system allows for more uniform temperature distribution. By redirecting air along walls and ceilings, this system prevents hot or cold spots, ensuring that the entire space is evenly heated or cooled. This feature is especially important in homes with open floor plans or multiple rooms, as it guarantees consistent comfort throughout the house.
Smart Technology for Maximum Efficiency
The Sharp ZHU heat pump is equipped with smart technology that takes comfort and efficiency to the next level. With motion sensors that detect when someone is in the room, the system can adjust its operation to minimize energy waste. When no movement is detected, the unit enters an energy-saving mode, further reducing utility bills.
Homeowners can also use the smartphone app to monitor and adjust the system in real-time, whether they are at home or away. The app provides detailed information on energy consumption, temperature, and humidity levels, allowing users to make informed decisions about their HVAC usage.
Environmentally Friendly Refrigerant for a Greener Future
At AirGreen, we are committed to providing environmentally responsible solutions to our clients. The R-32 refrigerant used in the Sharp ZHU series not only reduces the unit’s environmental impact but also helps homeowners save on energy costs. With a lower global warming potential than traditional refrigerants, R-32 represents the future of sustainable HVAC technology.
By choosing a heat pump that uses R-32, homeowners are making a choice that benefits both their wallets and the planet. The energy-efficient operation of the ZHU series means less electricity consumption and a smaller carbon footprint, aligning with our mission to offer eco-friendly HVAC solutions.

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.

Your own project, step by step
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.
