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.
Enhancing Comfort with Innovative Technology: The Sharp ZHU Heat Pump
In the bustling cityscape of Montreal, where the climate swings from icy winters to sweltering summers, maintaining an optimal home environment is not just a luxury—it's a necessity. At AirGreen, our mission is to provide cutting-edge HVAC solutions that not only excel in performance but also blend seamlessly with your home aesthetics and environmental goals. Our recent installation of the Sharp ZHU wall-mounted heat pump exemplifies this commitment.
A Tailored Installation Experience
Every installation has its story, and the Sharp ZHU installation in a quaint Montreal neighborhood is no different. Nestled in the upper corner of a stylishly minimalist living room, this 18,000 BTU machine boasts a sleek design that complements the modern interior décor. Beyond its appearance, the strategic placement ensures optimal airflow, reaching every nook of the space without disrupting the room's ambiance.
The ZHU model is particularly notable for its grant eligibility, providing homeowners up to $700 through the LogisVert Grant by Hydro-Québec, and substantial federal grants of up to $5,000. Such financial incentives make the ZHU an attractive choice for eco-conscious residents looking to upgrade their home systems efficiently.
Technical Brilliance Unveiled
What sets the Sharp ZHU apart are its advanced features tailored to Montreal's unique climate challenges:
- Dual Cooling and Heating Capacity: Capable of operating efficiently even at -27°C, this unit promises year-round comfort.
- Energy Efficiency: With a SEER rating of 25.0, the ZHU is one of the most efficient models on the market, reducing household energy consumption significantly.
- Silent Operation: The indoor unit operates as quietly as 25 dB(A), ensuring that your home remains a serene sanctuary.
Innovations That Breathe Life
The ZHU series doesn't just regulate temperature—it transforms your living environment. Equipped with Plasmacluster technology, the unit goes beyond traditional HVAC functions to actively purify the air. This feature eliminates airborne viruses, mold, and odors, enhancing indoor air quality profoundly. The nature-inspired fan blade design, mimicking dragonfly and bird wings, not only enhances airflow efficiency by up to 30% but also reduces operational noise, making it a silent guardian of your comfort.
The Coanda Effect: A Symphony of Airflow
Our installation also highlights the ZHU's innovative Coanda airflow technology, which intelligently directs air to provide even temperature distribution throughout the room. This avoids the common discomfort of direct air blasts, ensuring a gentle yet effective spread of air.
Seamless Integration and Smart Controls
Integration with home networks is seamless, thanks to built-in WiFi capabilities, allowing homeowners to control their climate settings from any smart device. Real-time monitoring of temperature and energy usage helps maintain efficient operation and comfort.

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.
