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.
Experience Ultimate Comfort in Verdun with the Sharp BU Triple Zone Heat Pump
At AirGreen, we recently completed an installation in Verdun, Montreal, that showcases our commitment to bringing top-tier HVAC solutions to the community. This time, our team installed a Sharp BU Triple Zone Heat Pump, a cutting-edge unit designed to provide year-round comfort with maximum energy efficiency. The installation features a 24,000 BTU outdoor compressor paired with three 12,000 BTU indoor units, making it an ideal choice for homeowners looking for versatile and reliable temperature control across multiple rooms.
Meeting the Needs of a Growing Verdun Household
The homeowner approached us with a growing family and an increased need for reliable heating and cooling. As the demand for comfort across different parts of the house grew, so did the need for a solution that could efficiently manage temperature variations across three separate zones. Our team recommended the Sharp BU Triple Zone Heat Pump, a unit well-known for its performance and reliability, even in extreme cold conditions down to -27°C. With three indoor units strategically installed in the living room, master bedroom, and home office, the family now enjoys consistent comfort no matter the season or the time of day.
Advanced Technology for Superior Air Quality
One of the standout features of the Sharp BU Heat Pump is its Plasmacluster air purification technology. This system uses positive and negative ions to eliminate airborne contaminants, ensuring that the indoor environment remains free of bacteria, viruses, and allergens. For families like the one in Verdun, where health and wellness are a top priority, this feature brings added peace of mind. Unpleasant odors from cooking, pets, or even daily living are also significantly reduced, creating a fresh and welcoming atmosphere throughout the home.
Why the Sharp BU Triple Zone Heat Pump Is Perfect for Montreal's Climate
Montreal’s weather can be notoriously unpredictable, with scorching summers and harsh, frigid winters. The Sharp BU Triple Zone Heat Pump is designed to handle these extremes effortlessly. It features a heating capacity that remains efficient down to -27°C, making it one of the most reliable options available for keeping your home warm and cozy during the winter months. The unit’s 24.0 SEER rating also ensures that you’re getting some of the highest energy efficiency on the market, which translates to lower energy bills and a reduced environmental footprint.
The "HOT GAS PIPE" System: Combatting Cold Weather Like No Other
Montreal winters are no match for the HOT GAS PIPE system integrated into the Sharp BU Heat Pump. This technology uses residual heat from the defrosting process to prevent ice from forming on the exterior unit, which can be a common issue in sub-zero temperatures. As a result, the heat pump maintains uninterrupted performance, keeping your home warm even during the coldest days.
Optimized Comfort with the Coanda Effect
For a comfortable indoor environment, it’s not just about temperature—it’s also about how the air is distributed. The Coanda effect utilized by the Sharp BU directs air along the walls and ceilings instead of blowing directly at occupants, ensuring a more even distribution of warm or cool air. This results in balanced room temperatures and eliminates the discomfort associated with direct airflow, making it perfect for family settings where everyone’s comfort is important.
An Environmentally Friendly Choice with R-32 Refrigerant
AirGreen is committed to providing solutions that are environmentally responsible, and the Sharp BU Triple Zone Heat Pump aligns perfectly with this mission. The system uses R-32 refrigerant, which has a significantly lower global warming potential (GWP) compared to traditional refrigerants like R-22 or R-410A. This makes it a more sustainable choice for homeowners who want to reduce their impact on the environment. Additionally, R-32 is easier to recover and recycle, ensuring that even in the long run, the heat pump remains a green choice.
Easy Control with Built-In WiFi
The built-in WiFi functionality allows the homeowner to control the temperature settings from anywhere using a smartphone or tablet. This means they can adjust the heating or cooling even when away from home, ensuring the house is always at the perfect temperature upon arrival. For the family in Verdun, this level of convenience was a key factor in choosing the Sharp BU Heat Pump, allowing them to manage energy consumption more effectively and tailor comfort to their lifestyle.
Effortless Maintenance with Self-Cleaning Functionality
Another valuable feature is the self-cleaning mode, which uses Plasmacluster ions to keep the indoor units free from mold and dust buildup. This function not only extends the lifespan of the heat pump but also reduces the need for frequent maintenance, saving the homeowner both time and money.
The Details That Matter: Why This Installation Stands Out
The exterior unit, measuring 33.47 x 13 x 27.94 inches, was carefully installed in a well-ventilated area to ensure optimal performance and ease of maintenance. We also made sure that the sound pressure level of 50 dB(A) remains unobtrusive, keeping the outdoor ambiance of this Verdun neighborhood peaceful. Each of the three indoor units was mounted in locations that maximize airflow while complementing the home's interior design.
For the outdoor unit, we took extra measures to secure it against the harsh winter conditions typical in Montreal. The installation included protective brackets and anti-vibration pads, ensuring the unit stays stable and operates quietly even during the coldest months.
Maximizing Savings with the LogisVert Grant
This particular model is eligible for the LogisVert Grant by Hydro-Québec, with a $3,000 rebate. This financial incentive not only makes the Sharp BU Triple Zone Heat Pump an affordable option but also highlights its energy-efficient design. For many homeowners in Verdun, Montreal, and across Greater Montreal, this grant can significantly reduce the upfront cost of upgrading their HVAC system, making it a smart investment in long-term savings.

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.

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.
