Installation of a Sharp ZU1 Wall-Mounted Heat Pump in Saint-Bruno
Discover the comfort and energy efficiency of the Sharp ZU1 15,000 BTU heat pump, installed by AirGreen in Saint-Bruno. Eco-friendly, quiet, and powerful, it's the perfect solution for Quebec’s climate!

In summer, the outdoor unit rejects the house's heat outside.

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 to New Heights with Sharp ZU1 Mini-Split in Saint-Bruno
At AirGreen, we’re proud to serve clients across Greater Montreal, Laval, Longueuil, the North Shore, and the South Shore with high-quality HVAC solutions. Recently, our team completed an impressive mini-split installation for a home in Saint-Bruno, featuring the cutting-edge Sharp ZU1 15,000 BTU wall-mounted heat pump. This installation is a perfect example of how we bring comfort, efficiency, and reliability to our customers’ homes—especially as we head into another frigid Quebec winter.
Why Sharp ZU1? A Game-Changer in Home Comfort
The Sharp ZU1 heat pump offers an exceptional blend of performance, affordability, and eco-friendliness. This unit is capable of both cooling and heating, making it perfect for homes in Quebec’s climate where we experience extreme temperatures, from hot summer days to harsh winters. One of its most standout features is its ability to operate at outdoor temperatures as low as -27°C—a critical advantage for homeowners looking for reliable heating during Quebec’s brutal cold spells.
But there’s more: the Sharp ZU1 is the first mini-split in its class to use the revolutionary R-32 refrigerant, which is not only greener and more energy-efficient but also complies with the new government standards coming into effect in 2025. This ensures that your HVAC system is future-proof and aligned with evolving energy-efficiency regulations. And, with Energy Star® certification, it guarantees that your home stays warm while keeping energy consumption in check.

Highlights of the Installation
For this particular project in Saint-Bruno, the homeowner was looking for a heating and cooling solution that could handle the challenging weather conditions of Quebec while keeping energy bills low. The Sharp ZU1 was the perfect choice.
- Cooling Capacity: 15,000 BTU
- Heating Capacity: Functions seamlessly even at -27°C
- Efficiency Rating: An impressive 24.0 SEER
- Noise Levels: Quiet operation with just 23 dB(A) indoors—perfect for maintaining a peaceful home environment
- Admissible for the LogisVert Grant: The Sharp ZU1 model qualifies for the highest $2,172 LogisVert grant from Hydro-Québec, making it the most attractive option for a 15,000 BTU unit in the province.
The Installation Process: A Seamless Experience
For this project, we took great care to ensure that the installation was executed to perfection. Our experienced team arrived at the home in Saint-Bruno early in the morning, equipped with all the necessary materials to install the Sharp ZU1 wall-mounted heat pump. The exterior unit was mounted securely on the brick wall, and meticulous attention was given to running the piping and wiring in a way that is both functional and aesthetically pleasing.
Given the extreme weather conditions in Quebec, we ensured that the Sharp ZU1 heat pump was installed with its defrost mode and multiple drainage holes fully operational to avoid any freezing issues in the harsh winter months. The anti-corrosive coating on the outdoor unit also guarantees a longer lifespan, even with the wear and tear of Quebec's harsh winters.
Superior Features of the Sharp ZU1
One of the standout features of this heat pump is Plasmacluster technology, a unique air purification system that eliminates airborne bacteria, mold, and viruses, ensuring that the air in your home is not only comfortable but also healthy. This technology is exclusive to Sharp, making it a go-to option for customers who want clean air circulating through their home.
- Airflow Control with Coanda Effect: The Sharp ZU1’s Coanda effect ensures that the airflow reaches every corner of the room without blowing directly onto the occupants, making it a more comfortable option for daily use.
- Inverter Technology: This mini-split comes equipped with Sharp's inverter technology, allowing the system to run more efficiently, reduce energy waste, and maintain a steady indoor temperature.
- Multizone Capability: With its multi-space function, the Sharp ZU1 can distribute air to several rooms, making it ideal for homes with multiple floors or larger spaces.
Energy Efficiency and Environmental Responsibility
At AirGreen, we care deeply about the environment, and the Sharp ZU1 aligns with our mission of delivering eco-friendly solutions. The R-32 refrigerant used in this model is not only more efficient but also reduces the appliance's carbon footprint by about 10%, compared to older models that rely on R-22 or R-410A refrigerants. This means homeowners can enjoy a more sustainable lifestyle without sacrificing comfort or performance.
A Smart Home HVAC Solution
This model also comes with integrated Wi-Fi connectivity, enabling homeowners to control their heat pump remotely via a smartphone app. Whether you're at home or away, you can easily adjust the temperature, check energy consumption, or even set schedules for the unit—all with a few taps on your phone. Plus, with the app's real-time temperature and humidity monitoring, the Sharp ZU1 ensures you're always aware of the comfort levels in your home.

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.
