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.
Superior Comfort and Energy Efficiency with the Sharp ZHU Series
At AirGreen, we are passionate about delivering high-quality, efficient HVAC systems to homes across Montreal, Laval, Longueuil, and beyond. Recently, our skilled team completed the installation of a Sharp ZHU wall-mounted heat pump in Laval, and we couldn't be more proud of the results. This installation not only enhances the comfort of the homeowner but also offers substantial energy savings and environmental benefits.
A Closer Look at the Sharp ZHU Heat Pump
The Sharp ZHU series is a top-tier choice for anyone seeking reliable heating and cooling in Quebec’s harsh climate. This particular unit boasts a cooling capacity of 18,000 BTU and can handle temperatures as low as -27°C during winter. The powerful yet quiet system provides the perfect balance between performance and efficiency.
The ZHU model we installed is specifically designed to handle Quebec’s fluctuating weather conditions. Whether it’s the peak of summer or the dead of winter, this unit will keep the home comfortable year-round. Its 25.0 SEER efficiency rating and use of the R-32 refrigerant mean lower electricity bills and a reduced environmental footprint.
The Installation Process: Why This Job Stood Out
When we arrived at the Laval home, the first thing we noticed was how well-suited the property was for a wall-mounted heat pump. The external unit was placed on a solid brick wall, which not only provided a stable and secure installation point but also complemented the aesthetic of the home.
The indoor unit was carefully positioned to ensure maximum airflow throughout the house. With dimensions of 41.42 x 9.80 x 12.44 inches, the indoor head of the Sharp ZHU heat pump is sleek and modern, blending seamlessly into the home’s interior.
Our team of certified technicians followed strict guidelines to ensure optimal system performance. This included precise measurements to position the 1/4 - 3/8 inch pipes and secure wiring to the 220V power source. The installation was completed in a matter of hours, minimizing disruption to the homeowners.
Why the Sharp ZHU Heat Pump is a Game Changer for Laval Residents
The Sharp ZHU model is perfect for those who prioritize both comfort and sustainability. Here’s what makes this installation particularly noteworthy:
- Eligible for Government Grants: The homeowners will receive a $700 LogisVert Grant from Hydro-Québec. This makes the Sharp ZHU a highly cost-effective solution.
- Energy Star Certified: The ZHU series is Energy Star® Cold Climate certified, ensuring high performance even during Laval’s cold winters. This also means eligibility for an additional $2,500 Federal Grant.
- Wi-Fi Connectivity: The built-in Wi-Fi system allows the homeowners to control the heat pump remotely via their smartphone. They can monitor real-time temperature and humidity levels and even adjust settings on the go.
- Plasmacluster Technology: This patented air purification system from Sharp neutralizes viruses, bacteria, and mold, ensuring that the indoor air quality remains pristine.
- Noise Levels: Operating at a remarkably low 25 dB(A) indoors and 52 dB(A) outdoors, this heat pump is one of the quietest on the market, making it ideal for residential areas.
Meeting the Homeowner's Needs: A Tailored Approach
Every home and family has unique needs, and our goal is always to provide personalized solutions. For this particular project, the homeowners expressed their desire for an energy-efficient system that could handle Laval’s extreme temperatures without compromising on comfort.
The Sharp ZHU not only met but exceeded their expectations. The unit's Coanda Airflow technology ensures even temperature distribution across multiple rooms, and its Plasmacluster air purification system keeps the air free from allergens and contaminants, providing peace of mind for the homeowners.
With the multi-zone functionality, they can now control the temperature in different parts of their home, ensuring maximum comfort in every room.

Why the Sharp ZHU is Perfect for Quebec Winters
One of the standout features of the Sharp ZHU is its ability to operate efficiently in extreme cold. While many heat pumps struggle to provide warmth when temperatures dip below -15°C, the ZHU series is specifically engineered for cold climates, maintaining its heating capacity all the way down to -27°C. This makes it a perfect choice for the harsh winters in Laval and other regions in Quebec.
Additional Features of the Sharp ZHU Heat Pump
- Inverter Technology: The Sharp ZHU features advanced inverter technology, which ensures that the unit runs at optimal efficiency by adjusting its speed based on the room’s temperature. This not only improves energy efficiency but also prolongs the life of the system.
- Anticorrosive Coating: The Sharp ZHU comes with a special anticorrosive coating on its external parts, ensuring long-term durability even in Quebec’s challenging weather conditions.
- Auto Restart and Quick Defrost: In case of a power outage, the system will automatically restart with its previous settings. The Quick Defrost feature ensures that the unit’s outdoor compressor remains free of ice, which is essential for maintaining performance during the winter months.

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.
