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.
Elevating Comfort with AirGreen's Latest Installation: The Sharp BU Triple Zone Heat Pump in Plateau-Mont-Royal
When it comes to reliable heating and cooling solutions, AirGreen consistently delivers top-notch services across Montreal, Laval, Longueuil, the North Shore, and South Shore. Our latest installation in Plateau-Mont-Royal showcases the power and efficiency of the Sharp BU Triple Zone Heat Pump, designed to cater to the unique climate challenges of the area. This recent project involved installing a 24,000 BTU compressor with three 9,000 BTU indoor units, providing a tailored solution for multi-zone temperature control.
Meeting Local Needs with High-Performance HVAC
In the heart of Plateau-Mont-Royal, known for its vibrant communities and historic charm, homeowners face unique comfort needs. The fluctuating temperatures and humid conditions call for an HVAC system that adapts effortlessly to seasonal changes. The Sharp BU Triple Zone Heat Pump was selected for this very reason, offering superior cooling capabilities in the summer and efficient heating down to -27°C during harsh winters. With Energy Star® certification and a 24.0 SEER rating, this installation ensures not only comfort but also long-term savings on energy costs.
Installation Challenges and Solutions
The installation site, a cozy apartment in Plateau-Mont-Royal, presented a few challenges that our team expertly navigated. With the building's older architecture, there were limited options for placing the outdoor unit without compromising aesthetics or functionality. We managed to install the 33.47 x 13 x 27.94-inch exterior unit discreetly, ensuring it blended seamlessly with the building's exterior. To maintain the apartment's clean and modern interior look, we mounted the indoor units in strategic locations for optimal air distribution, thanks to SHARP's Coanda effect technology.

A Deeper Look into the Features: What Makes the Sharp BU Triple Zone Stand Out?
Advanced Plasmacluster Technology for Cleaner Air
One of the standout features of the Sharp BU Triple Zone Heat Pump is its Plasmacluster air purification technology. This system releases positive and negative ions to neutralize airborne pathogens, including bacteria, viruses, and mold. It also helps eliminate common household odors from cooking, pets, or tobacco, keeping indoor air fresh and inviting. The homeowners were particularly pleased with this feature, as it significantly improved air quality, benefiting family members with allergies and asthma.
R-32 Refrigerant for Environmental Efficiency
AirGreen is committed to sustainable practices, which is why the choice of R-32 refrigerant was ideal for this project. With a lower Global Warming Potential (GWP) compared to traditional refrigerants like R-22 or R-410A, R-32 reduces the environmental impact of heating and cooling systems. Moreover, its energy-efficient properties allow for better heat transfer, which translates to lower energy consumption and cost savings.
Harnessing the Coanda Effect for Optimal Comfort
The Coanda effect, a key feature in Sharp's technology, revolutionizes indoor air distribution. Instead of blowing air directly onto occupants, the heat pump uses this effect to direct air along walls and ceilings, resulting in even temperature distribution. This unique approach avoids drafts and creates a more consistent climate throughout the space. The homeowners reported feeling more comfortable immediately after the system was up and running, with no hot or cold spots in the apartment.
Exceptional Cold Weather Performance: The "HOT GAS PIPE" System
Montreal winters are notoriously harsh, with temperatures frequently dipping below freezing. The Sharp BU Triple Zone Heat Pump is equipped with the patented "HOT GAS PIPE" system, which ensures reliable heating even in extreme cold. By utilizing residual heat during the defrosting process, this system prevents ice buildup on the outdoor unit, maintaining optimal performance down to -27°C. This feature not only ensures year-round comfort but also enhances the system's energy efficiency by minimizing heat loss.

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.
