Installation of a SHARP BU Triple Zone Heat Pump in Deux-Montagnes
Discover how AirGreen transformed comfort in Deux-Montagnes with the SHARP BU Triple Zone Heat Pump—delivering cleaner air, maximum efficiency, and smart zone control for year-round comfort.
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.
Enhancing Comfort and Efficiency in Deux-Montagnes with SHARP’s Advanced Triple Zone Heat Pump
At AirGreen, we pride ourselves on providing state-of-the-art HVAC solutions to residents across Montréal, Laval, Longueuil, Rive Nord, and Rive Sud. Our recent project in Deux-Montagnes featured the installation of a SHARP BU Triple Zone Heat Pump, an exceptional system that combines energy efficiency, advanced features, and unmatched comfort.
This heat pump installation wasn’t just another routine job—it was a solution crafted to meet the homeowner’s need for high-performance heating and cooling, adaptable for three different zones of their home. Let’s dive into the details and the unique features of this installation.
The Project: Why the SHARP BU Heat Pump?
Our client in Deux-Montagnes faced the classic challenge of maintaining consistent temperatures across multiple areas of their home. With the installation of the SHARP BU Triple Zone Heat Pump, we addressed their needs with a 24,000 BTU outdoor compressor connected to two 9,000 BTU indoor units and one 12,000 BTU indoor unit. This strategic configuration provided customized comfort for three separate zones, allowing precise temperature control where it mattered most.
This SHARP model not only delivers exceptional comfort but also stands out for its efficiency, operating seamlessly even in extreme cold down to -27°C. Given the harsh winters in Québec, this is a game-changer for reliable year-round performance.
Key Specifications of the SHARP BU Triple Zone Heat Pump
- Cooling Capacity: 24,000 BTU
- Heating Capacity: Efficient operation in temperatures as low as -27°C
- Efficiency: An impressive 24.0 SEER, ensuring significant energy savings
- Zones: 3 (Triple Zone)
- Refrigerant: R-32, the eco-friendly choice with lower global warming potential
- Energy Star® Certification: Yes, ensuring energy-efficient operation
- Noise Level: Quiet outdoor operation at 50 dB(A)
- WiFi Connectivity: Included for smart control via mobile devices
The installation was also eligible for the $3,000 LogisVert Grant offered by Hydro-Québec, making it a smart financial investment for our client.
Why SHARP Stands Out: Exceptional Technology and Innovation
Plasmacluster Technology: Cleaner, Healthier Air
One of the standout features of the SHARP BU series is its Plasmacluster air purification technology. By emitting positive and negative ions similar to those found in nature, this system actively removes airborne contaminants like bacteria, viruses, allergens, and mold spores. For families in Deux-Montagnes, this means a home environment that is not just comfortable but also healthier.
Benefits of Plasmacluster:
- Neutralizes airborne pathogens, reducing the risk of respiratory issues.
- Eliminates odors, ensuring fresh and clean indoor air.
- Improves air quality, particularly beneficial for individuals with allergies or asthma.
Energy Efficiency with R-32 Refrigerant
The R-32 refrigerant used in the SHARP BU system reflects a commitment to sustainability. With a lower global warming potential (GWP) than traditional refrigerants like R-410A, R-32 not only minimizes environmental impact but also enhances energy efficiency, reducing energy bills significantly for homeowners.
Heating Excellence: Reliable Performance in Cold Québec Winters
Québec winters can be unforgiving, but the SHARP BU heat pump is designed to thrive in extreme conditions. Its "HOT GAS PIPE" system ensures uninterrupted performance, even when temperatures plummet to -27°C. By using residual heat to prevent frost buildup, this system delivers consistent heating without compromising efficiency.
The Installation Process: Expertise and Precision
At AirGreen, every installation is handled with meticulous attention to detail. For this project in Deux-Montagnes:
- Site Assessment: We began with a thorough evaluation of the home to determine the optimal placement of the indoor and outdoor units.
- Unit Placement:
- The two 9,000 BTU indoor units were installed in the bedrooms to ensure quiet, efficient cooling and heating.
- The 12,000 BTU unit was placed in the living room for centralized comfort.
- Outdoor Installation: The 24,000 BTU compressor was mounted securely outside, ensuring maximum airflow and efficiency.
- System Calibration: Once installed, we calibrated the system for WiFi connectivity and optimal performance, allowing the client to control their heat pump with ease from a mobile device.
The result? A system that delivers whisper-quiet operation, customized zone control, and reliable year-round comfort.
Customer Benefits: What Makes This System Perfect for Deux-Montagnes Homes
The SHARP BU Triple Zone Heat Pump brings a host of benefits to homeowners, including:
- Energy Savings: With a 24.0 SEER rating, this system significantly reduces electricity costs.
- Customizable Comfort: Independent zone control allows personalized temperatures for each area of the home.
- Quiet Operation: Indoor units are engineered to operate at low sound levels, creating a peaceful indoor environment.
- Enhanced Air Quality: Thanks to Plasmacluster technology, the air is purified continuously.

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.
