Triple Zone Heat Pump SHARP BU | Montreal, Laval, Longueuil, South Shore & North Shore
A Giant Leap in Home Comfort with the Double Zone SHARP BU Heat Pump
In the quest for a home where thermal comfort aligns with exceptional air quality, the Double Zone SHARP BU Heat Pump stands out as an unparalleled solution. Designed to meet the specific climate challenges of Montreal, Laval, Longueuil, as well as the South Shore and North Shore, this HVAC (Heating, Ventilation, and Air Conditioning) system integrates major innovations such as Plasmacluster technology and the use of R-32 refrigerant, establishing a new standard in terms of performance, energy efficiency, and environmental respect.
The Plasmacluster Revolution: Beyond Simple Air Conditioning
At the heart of the Double Zone SHARP BU Heat Pump, Plasmacluster technology goes beyond traditional air conditioning expectations by offering unmatched air purification. Through the emission of positive and negative ions, this technology mimics nature's air purification mechanisms, effectively neutralizing viruses, bacteria, allergens, and odors. This process, in addition to regulating indoor temperature, ensures a healthy indoor environment, crucial for the occupants' well-being.
Impact on Health and Comfort
- Pathogen Reduction: Plasmacluster's efficacy in neutralizing airborne viruses and bacteria contributes to reducing the risks of respiratory disease transmission, providing additional protection for your home.
- Allergen Elimination: By reducing the presence of allergens such as dust mites and pollen, this technology significantly improves the quality of life for people with allergies or asthma.
- Odor Neutralization: Plasmacluster ions break down and eliminate persistent odors, ensuring a constant fresh sensation in your home.
The R-32: A Revolutionary Refrigerant for a Sustainable Future
The adoption of R-32 refrigerant by the Double Zone SHARP BU Heat Pump represents a strong commitment to environmental preservation. With a significantly lower global warming potential (GWP) than traditional refrigerants, R-32 optimizes energy performance while reducing the ecological footprint of your air conditioning system.
Environmental and Economic Benefits
- Increased Efficiency: Thanks to its superior heat transfer capacity, R-32 allows a significant reduction in energy consumption, translating into substantial savings on electricity bills.
- Reduced Environmental Impact: The low GWP of R-32 helps to minimize the impact of air conditioning systems on global warming, aligning the use of your heat pump with sustainable development goals.
- Recyclability: Unlike some composite refrigerants, R-32 is easily recyclable, facilitating environmental management at the end of your equipment's life.
Innovation at the Heart of Design: The Coanda Effect
- Comfort Optimization: The cutting-edge technology of the Coanda effect is a central pillar of the Double Zone SHARP BU Heat Pump. By exploiting this natural phenomenon, the system directs cold or warm air along surfaces (walls or ceiling), promoting a uniform distribution and avoiding direct contact of air with people. This revolutionary approach ensures increased comfort in all rooms, without the unpleasant drafts characteristic of traditional systems.
- An Innovation Inspired by Nature: Inspired by the natural movement of air and fluids, the Coanda effect optimizes air flow for a more natural and widespread feeling of well-being. This technology is the result of extensive research and precise engineering, aimed at replicating the most pleasant conditions of air circulation in the home environment.
«HOT GAS PIPE» System (Patented): A Response to Harsh Climates
- Exceptional Performance in Cold Weather: The «HOT GAS PIPE» system, a SHARP exclusive, is specially designed to offer optimal performance even in the extreme winter conditions of Montreal and its surroundings. By preventing ice formation on the external unit, this technology ensures continuous operation and superior energy efficiency, even at temperatures down to -27°C.
- Innovation and Reliability: Thanks to this patented system, the Double Zone SHARP BU Heat Pump positions itself as a reliable and durable heating solution, reducing the need for maintenance and increasing the appliance's longevity. This feature makes this heat pump a wise investment for homeowners concerned with performance and durability.
Self-Cleaning Function: Cleaner Air, Effortlessly
- Continuous Purification: One of the most remarkable features of the Double Zone SHARP BU Heat Pump is its ability to maintain superior indoor air quality thanks to its self-cleaning function. By incorporating Plasmacluster technology, this device neutralizes bacteria, viruses, mold, and allergens present in the air, ensuring a healthy environment for all occupants.
- Reduced Maintenance: Beyond its health benefits, the self-cleaning function significantly simplifies the maintenance of the heat pump. By minimizing the proliferation of mold and other pathogens inside the appliance, it extends the lifespan of the heat pump and maintains its energy efficiency over time.
Capacity to Manage Two Distinct Zones: Unmatched Flexibility
Unlike traditional systems, the Double Zone SHARP BU Heat Pump is specifically designed to manage two distinct comfort zones. This feature allows for advanced customization of the indoor climate, adapting the temperature of each zone to individual preferences and the specific uses of different areas of your home.
Conclusion: A Major Advance for Home Comfort
The Double Zone SHARP BU Heat Pump from AirGreen revolutionizes the concept of home comfort, combining precise temperature control, advanced air purification through Plasmacluster technology, and optimized energy efficiency through the use of R-32 refrigerant. By choosing this solution for your home in Montreal, Laval, Longueuil, or on the South Shore and North Shore, you opt for a heating and cooling system that respects both your well-being and the environment.
What people ask us about multi-zone systems.
Can I heat one room and cool another at the same time?
No. On a multi-zone system like this one, every head works in the same mode, heating or cooling. Each room still keeps its own set temperature.
What happens when every room calls for heat?
They share the outdoor unit’s capacity: 25,000 BTU/h at −8 °C, 21,200 at −15 °C.
How many heads can I connect?
Up to 3 on this outdoor unit. This product is configured for 2 heads.
Can I mix head sizes?
Yes. The “Zones” menu offers 6 combinations, from 9 + 9 to 18 + 18 (in thousands of BTU). Each head is sized for its room.
How much is the LogisVert grant?
$3,000 according to Hydro-Québec’s list of October 1, 2026. The grant never exceeds 100 % of the cost before taxes; apply within 9 months of installation.
Is it ENERGY STAR certified?
Yes, cold climate, ID 3391682. It also meets the ENERGY STAR Most Efficient criteria, according to the ENERGY STAR database.
Down to what temperature does it heat?
Down to −27 °C.
Is it noisy?
Indoors, the reference head goes down to 23 dB(A). Outdoors, 50 dB(A): we place the unit away from bedroom windows.
Why a multi-zone instead of several wall units?
One outdoor unit on the wall and one circuit. In return, the rooms share the capacity, and if the outdoor unit stops, every zone stops.
What does the warranty cover?
Our sheet lists 10 years on the compressor and 10 years on parts; labour is not included by the manufacturer. AirGreen extended warranty: included.
A multi-zone system is planned room by room. At your home.
We measure every room, draw the line route and choose the right head for each zone. The on-site estimate is free and the quote arrives within 24 h.
