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.
Exceptional HVAC Installation to Beat the Quebec Cold
At AirGreen, we specialize in offering efficient, eco-friendly HVAC solutions across the Greater Montreal area. This time, we completed an installation of a Sharp ZU1 Wall-Mounted Heat Pump in a beautiful home located in Beaconsfield. This cutting-edge unit, offering a robust 18,000 BTU capacity, is designed to withstand the harsh Canadian winters, ensuring optimal comfort for homeowners even in extreme temperatures as low as -27°C. With the added benefit of being eligible for a $2,640 LogisVert Grant by Hydro-Québec, this installation offers both comfort and financial incentives.
The Perfect System for Harsh Winters
Our client needed a heat pump that could perform exceptionally in all seasons, particularly during Quebec’s frigid winters. After an extensive consultation, we determined that the Sharp ZU1 was the ideal choice for the property. This unit boasts a cooling capacity of 18,000 BTU and the ability to operate efficiently in extreme cold, making it the perfect solution for ensuring comfort year-round. Whether it’s keeping cool in the summer or cozy during the coldest months, this Sharp ZU1 will perform flawlessly.
Superior Technology at Work
Plasmacluster Technology for Clean Air
One standout feature of the Sharp ZU1 Heat Pump is its Plasmacluster technology, which sets it apart from competitors. Plasmacluster works by generating positive and negative ions, replicating the natural purification process that occurs in nature. These ions neutralize harmful airborne bacteria, viruses, and mold spores, providing the healthiest possible indoor air quality. Not only does this technology help maintain the comfort of your home, but it also safeguards the health of your family by eliminating allergens and odors. It’s one of the many reasons why Sharp is a leader in air purification.
Coanda Airflow for Even Distribution
In addition to superior air purification, the Sharp ZU1 features Coanda airflow control, ensuring that heated or cooled air is evenly distributed throughout the home. Instead of blasting air directly onto occupants, this system uses natural airflow dynamics to circulate the air along the walls and ceilings, creating a balanced and comfortable environment. This prevents temperature disparities between rooms and ensures that every corner of the house enjoys the same level of comfort. The Coanda effect is particularly beneficial in homes with multiple rooms, making the Sharp ZU1 a standout choice for large properties or multi-story homes.
An Installation Designed for Comfort and Efficiency
Our experienced AirGreen technicians installed the Sharp ZU1 heat pump with the utmost precision, ensuring optimal performance and longevity. The indoor unit, with its sleek dimensions of 41.42 x 9.80 x 12.44 inches, was installed discreetly to blend with the interior décor, while the exterior unit, measuring 33.47 x 13 x 27.94 inches, was mounted securely to the exterior wall. The installation was completed with insulated piping and proper drainage to ensure smooth and efficient operation, even during winter defrost cycles.
The unit also operates with R-32 refrigerant, which is not only more efficient but also eco-friendlier, significantly reducing the environmental impact compared to older refrigerants. This aligns with both AirGreen and Sharp's commitment to sustainability and energy efficiency.
Energy Efficiency and Financial Benefits
One of the key selling points for our Beaconsfield client was the financial savings. With an impressive SEER rating of 24.0, the Sharp ZU1 is highly energy-efficient, meaning lower energy bills while still maintaining optimal comfort levels. In addition to the energy savings, the $2,640 LogisVert Grant from Hydro-Québec made the decision to install this model even more compelling. This grant is part of Hydro-Québec’s initiative to encourage the use of more energy-efficient appliances, making this Sharp ZU1 heat pump both an eco-friendly and cost-effective solution.
Quiet and Comfortable Operation
Noise can be a concern when installing HVAC systems, but the Sharp ZU1 excels in this area as well. The interior unit operates at a whisper-quiet 25 to 49 dB(A), ensuring that even in the quietest parts of the day or night, the system remains unobtrusive. The exterior unit, similarly, produces a modest 52 dB(A), which is quieter than a standard conversation. This makes the Sharp ZU1 an excellent option for urban and suburban homes where noise levels are a concern.
Why Choose AirGreen for Your HVAC Needs?
At AirGreen, we pride ourselves on providing high-quality HVAC services that meet the unique needs of Quebec homeowners. Our team of certified technicians ensures that each installation is completed to the highest standard, guaranteeing both performance and peace of mind. We take the time to understand each client’s specific requirements and recommend the best system to meet their needs, while also ensuring they benefit from any available grants or financial incentives.
Long-Lasting Reliability with Comprehensive Warranties
The Sharp ZU1 is designed to provide long-lasting performance, and it comes with a 10-year warranty on the compressor, parts, and labor. Additionally, AirGreen offers an extended 10-10-10 warranty, so our clients can rest easy knowing that their investment is protected for years to come. This, combined with the unit’s superior build quality, means the homeowners in Beaconsfield can enjoy uninterrupted comfort for many years.

A Greener Future with R-32 Refrigerant
In line with modern environmental standards, the Sharp ZU1 uses R-32 refrigerant, which offers improved energy efficiency and a lower environmental impact compared to older refrigerants like R-22. By choosing this model, the homeowners are not only saving on energy costs but also contributing to a greener future. This refrigerant has a lower global warming potential, making it a smarter choice for both the environment and long-term energy savings.

And at your place?
Two quick checks with real numbers: what heat costs, and what your current heaters add up to in BTU/h.
Baseboards and electric furnaces turn 1 kWh of electricity into 1 kWh of heat. A heat pump delivers more: that is its COP. At Hydro-Québec’s rate D (11.142¢/kWh above 40 kWh a day, since 1 April 2026):
Hydro-Québec: a heat pump can be up to three times more efficient than baseboards for heating in the colder months.
Estimate per kWh of heat, at the chosen temperature, using the certified COP from the product page. Taxes, access charge and backup heat not included.
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.
