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.
Bringing Superior Comfort and Energy Efficiency to Montreal Homes
At AirGreen, we pride ourselves on delivering exceptional HVAC solutions tailored to meet the unique needs of every home in Montreal and its surrounding areas. This week, we had the pleasure of installing the innovative SHARP ZU1 15,000 BTU Wall-Mounted Heat Pump in a charming residence located in Côte-des-Neiges. This cutting-edge heat pump is not only designed to keep homes comfortable during Montreal’s blistering summers and harsh winters but also offers advanced features that stand out in the world of HVAC systems.
Why the SHARP ZU1 is a Game-Changer
Performance at Extreme Temperatures
The SHARP ZU1 heat pump is engineered for reliability in extreme weather, a necessity in Quebec’s unforgiving climate. With a heating capacity that functions efficiently down to -27°C, this unit ensures warmth even during the most frigid winter days. Meanwhile, its cooling capacity of 15,000 BTU guarantees refreshing air during scorching summers.
Energy Efficiency at Its Best
With an impressive 24.0 SEER rating, this heat pump is designed to keep energy bills low while maintaining optimal performance. Additionally, its integration of R-32 refrigerant makes it a greener choice, reducing the environmental footprint and aligning with 2025 energy efficiency standards.
Highlights of the Côte-des-Neiges Installation
This installation was more than just about placing a heat pump; it was about enhancing the homeowner’s living experience. Here’s a breakdown of the work we completed:
Strategic Placement for Optimal Performance
Our team carefully assessed the layout of the home to ensure the outdoor unit was mounted securely and away from potential obstructions. The SHARP ZU1’s exterior unit, with its compact dimensions (30.72 x 10.59 x 21.25 inches), fit seamlessly on the side of the home without compromising aesthetics. The indoor unit, with dimensions of 41.42 x 9.80 x 12.44 inches, was installed in the living area for maximum airflow and efficiency.
Quiet Operation
One of the standout features of the SHARP ZU1 is its whisper-quiet operation. With an interior sound pressure level as low as 23 dB(A), this unit ensures a peaceful environment, perfect for relaxation or productivity.
Admissibility for the $2,172 LogisVert Grant
This heat pump qualifies for the highest possible grant for a 15,000 BTU unit under the LogisVert program, making it an economical choice for environmentally conscious homeowners.
Advanced Features of the SHARP ZU1
Plasmacluster Technology for Cleaner Air
The SHARP ZU1 goes beyond temperature control by integrating Plasmacluster technology, which purifies the air by eliminating bacteria, viruses, mold, and allergens. This ensures a healthier indoor environment for families.
Coanda Airflow Control
This advanced feature redirects airflow along walls and ceilings to distribute air evenly throughout the room, preventing hot or cold spots. Say goodbye to drafts and hello to consistent comfort.
Smart Connectivity
With built-in Wi-Fi capabilities, the SHARP ZU1 allows homeowners to control their heat pump remotely via a smartphone app. From adjusting temperature settings to monitoring energy usage, everything is just a tap away.

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.
