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 Home Comfort with Advanced HVAC Solutions
At AirGreen, we take pride in delivering cutting-edge HVAC solutions tailored to the specific needs of our clients. This recent installation of a SHARP BU Triple-Zone Heat Pump on the South Shore perfectly exemplifies our commitment to innovation, efficiency, and customer satisfaction. Equipped with a 24,000 BTU compressor and three 9,000 BTU indoor units, this setup is designed to provide seamless heating and cooling across multiple zones, ensuring year-round comfort in any weather conditions.
Understanding the Needs of the Homeowner
When our client approached us, they were looking for an HVAC system capable of efficiently regulating temperatures in three separate zones of their home. Their priorities included superior energy efficiency, quiet operation, and a system that could withstand the harsh winters typical of Québec, with temperatures often plummeting to -27°C. After an in-depth consultation, we recommended the SHARP BU Triple-Zone Heat Pump, a model renowned for its reliability, advanced technology, and environmental sustainability.
Key Features of the SHARP BU Triple-Zone Heat Pump
1. Exceptional Heating and Cooling Capacities
- Cooling Capacity: The 24,000 BTU compressor ensures consistent and powerful cooling during the sweltering summer months, while the 9,000 BTU indoor units provide precise climate control for individual rooms.
- Heating Capacity: Designed to function efficiently in temperatures as low as -27°C, this heat pump is perfect for Québec's challenging winters, ensuring warmth and comfort when you need it most.
2. Energy Efficiency and Environmental Responsibility
- SEER Rating: With an impressive 24.0 SEER, this model guarantees significant energy savings compared to conventional HVAC systems.
- R-32 Refrigerant: As an environmentally friendly refrigerant, R-32 offers reduced global warming potential (GWP), aligning with our client’s desire for a sustainable heating and cooling solution.
3. Advanced Indoor Air Quality Technology
- Plasmacluster Ion Technology: SHARP’s proprietary Plasmacluster feature purifies the air by neutralizing airborne pathogens, allergens, and odors. This ensures a healthier and fresher indoor environment for the entire household.
- Self-Cleaning Mechanism: The heat pump automatically initiates cleaning cycles to prevent mold growth and maintain optimum air quality, reducing maintenance requirements.
4. Multi-Zone Flexibility
- With three independent indoor units, the system allows for customized temperature settings in different areas of the home. This ensures maximum comfort for every family member, whether they are relaxing in the living room, working in the home office, or enjoying a good night's sleep in the bedroom.
The Installation Process: A Story of Precision and Expertise
Our team began by conducting a comprehensive site assessment to determine the optimal placement for the outdoor compressor unit and the indoor wall-mounted units. Given the homeowner's desire for a discreet setup, we strategically positioned the outdoor unit on a raised platform to prevent snow accumulation and ensure year-round efficiency. The sleek indoor units were installed in three key zones, blending seamlessly with the interior décor.
Technical Specifications of the Installed System
- Exterior Unit Dimensions: 33.47 x 13 x 27.94 inches
- Sound Pressure Level: A whisper-quiet 50.0 dB(A), ensuring minimal noise disruption.
- Voltage: 220V, delivering consistent and reliable power.
- Warranty: Comprehensive 10-year coverage for the compressor, parts, and labor.
Our technicians carefully routed the refrigerant and communication lines through the walls, utilizing protective coverings to enhance durability and aesthetic appeal. Despite the challenging installation conditions—working on elevated surfaces and navigating through tight spaces—we ensured a clean and professional finish.

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.
