Installation of a Sharp BU Double Zone Heat Pump in Senneville
Discover how we installed the Sharp BU Double Zone Heat Pump in Senneville, delivering ultimate comfort with two zones, advanced features, and energy efficiency!
In summer, the outdoor unit rejects the house's heat outside.
Generic illustration of this type of installation, not a survey of this job site. Tap a number.
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.
Where Comfort Meets Innovation: A Unique HVAC Project in Senneville
In the picturesque town of Senneville, where comfort meets tranquility, we at AirGreen recently completed a standout HVAC installation. This wasn’t just another heat pump setup—it was the installation of a Sharp BU Double Zone Heat Pump, an ideal solution for precise comfort control and year-round energy efficiency. Combining top-notch technology, a sleek design, and impressive specifications, this system delivers unmatched performance for modern households. Let us take you through the details of this project and the machine itself.
The Project: Perfect Comfort in Two Zones
The homeowner in Senneville sought an energy-efficient solution for both cooling and heating their space. After an in-depth consultation, we recommended the Sharp BU Double Zone Heat Pump—a 24,000 BTU system that efficiently powers two separate indoor zones:
- Zone 1: A 9,000 BTU indoor unit perfectly suited for the bedroom, ensuring quiet, peaceful comfort.
- Zone 2: An 18,000 BTU indoor unit installed in the living area for optimal heating and cooling of the main gathering space.
This setup provides not only precise temperature control but also remarkable energy savings, thanks to its 24.0 SEER efficiency rating and Energy Star® certification.
The Star of the Show: The Sharp BU Double Zone Heat Pump
Key Specifications at a Glance
- Cooling Capacity: 24,000 BTU
- Heating Capacity: Effective down to -27°C—perfect for harsh Québec winters
- Noise Level: Only 50.0 dB(A) for the exterior unit, ensuring whisper-quiet operation
- Gas Refrigerant: R-32, an eco-friendly choice for reducing environmental impact
- Voltage: 220V for reliable, powerful performance
- Warranty: 10 years for the compressor, parts, and labor
- WiFi-Enabled: Remote temperature control for seamless, modern living
With these advanced features, the Sharp BU ensures both comfort and savings throughout every season.
Why R-32 Refrigerant Matters
The use of R-32 refrigerant is a significant advantage of this system. Compared to traditional refrigerants, R-32 has a lower Global Warming Potential (GWP), meaning it’s not only highly efficient but also environmentally responsible. This aligns with AirGreen’s commitment to offering sustainable solutions that reduce both energy bills and ecological footprints.
A Picture-Perfect Installation
When it came to the installation itself, precision was paramount. The outdoor unit (33.47 x 13 x 27.94 inches) was strategically placed to minimize visual impact and maintain airflow efficiency, while the two indoor units seamlessly blended into their respective spaces.
The 9,000 BTU unit was mounted above a doorway in the bedroom. This spot was chosen carefully to distribute cool or warm air evenly across the room without creating drafts. In the living room, the larger 18,000 BTU unit was installed to maximize comfort for the entire space.
A Grant-Worthy System: $3,000 LogisVert Eligibility
The Sharp BU Double Zone Heat Pump is not just a high-performance system; it’s also an investment that pays off. This model is eligible for Hydro-Québec's LogisVert grant of up to $3,000, helping homeowners significantly reduce installation costs.
Additionally, this system ranked first in our Guide des Thermopompes Murales 2025, a testament to its superior efficiency, durability, and innovative features.
Why the Sharp BU Double Zone is the Ideal Choice
1. Flexibility for Multi-Zone Comfort
With its double-zone capability, the Sharp BU is designed for homeowners who want tailored comfort in different areas of the home. Whether you need a cooler bedroom for better sleep or a warm and cozy living area for family gatherings, this system delivers.

No one likes a noisy HVAC system. The Sharp BU operates at a near-silent level, ensuring a peaceful home environment. The exterior unit registers at just 50.0 dB(A), quieter than a standard conversation.
3. Winter-Ready Heating
The heating performance down to -27°C makes this heat pump a perfect solution for Québec winters. Even in frigid temperatures, the Sharp BU remains reliable and efficient.
4. WiFi Integration for Modern Living
Control your home’s climate from anywhere with the built-in WiFi feature. Whether you're adjusting temperatures from the comfort of your couch or remotely managing zones through your smartphone, the Sharp BU simplifies your life.

Among the year’s most efficient according to ENERGY STAR, on top of its cold-climate certification.
Minimum certified capacity (NEEP): it slows down instead of stopping when a single room calls.
NEEP still lists 14,600 BTU/h at a COP of 1.84 at −17 °F.
Global warming potential of R-32, versus 2,088 for R-410A (ENERGY STAR).

Data read live from the airgreen.ca page of each size (NEEP / AHRI certified performance). When the title names the installed size, it is highlighted; otherwise the whole range is shown. The aid shown is today’s, using Hydro-Québec’s rule ($120 per 1,000 BTU/h at −8 °C); amounts quoted in the article date from its publication. Only Hydro-Québec confirms the assistance granted.
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.
