Installation of a Sharp ZU1 Mini Split Heat Pump in Kirkland, Montreal
Discover how we installed the Sharp ZU1 heat pump in Kirkland, offering top-tier energy efficiency, air purification, and a $2,172 LogisVert grant. Perfect for Quebec’s extreme weather!
In summer, the outdoor unit rejects the house's heat outside.

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.
Why This Installation Stands Out
In the beautiful suburb of Kirkland, located on the West Island of Montreal, we recently completed an installation of a Sharp ZU1 15,000 BTU wall-mounted mini split heat pump. This project, while it may seem like a standard setup, had some unique features that made it particularly interesting for both our team and the homeowner. The Sharp ZU1 series is renowned for its advanced technology and high energy efficiency, which are key reasons why this installation qualifies for a $2,172 LogisVert grant from Hydro-Québec—currently the highest grant available for a 15,000 BTU unit in Quebec!
A Perfect Fit for Kirkland's Climate
Montreal winters can be brutally cold, and summers are known for their sweltering heat. The Sharp ZU1 mini split is designed to handle these extreme temperature fluctuations. This system provides reliable heating even when outdoor temperatures drop as low as -27°C, making it an ideal choice for Quebec's harsh winters. On the flip side, its cooling capabilities ensure that the home remains a cool haven during the hot summer months.
By opting for the Sharp ZU1, the homeowner not only invests in comfort but also in sustainability, as the ZU1 uses R-32 refrigerant, a more environmentally friendly option that helps reduce the home’s carbon footprint.
The Installation Process: A Unique Challenge
We were tasked with installing this heat pump in a somewhat unconventional spot—a staircase landing in the home. The placement of a unit in such a location required precise measurements and thoughtful planning. The goal was to ensure optimal air circulation throughout the main living areas while also making sure that the airflow wouldn’t be directly hitting the stairwell traffic.
Balancing Efficiency and Aesthetics
With any HVAC installation, especially in homes with unique architectural features, balancing functionality with aesthetics is crucial. The homeowner wanted the Sharp ZU1 to seamlessly blend into the interior design while maximizing the unit’s efficiency. To achieve this, our expert team at AirGreen carefully positioned the unit so that the airflow would distribute evenly across the room, making full use of the Coanda effect. This technology allows the air to follow the surfaces of the walls and ceilings, creating a more natural flow and ensuring that both heating and cooling are dispersed evenly throughout the space.
Why the Sharp ZU1 Was the Perfect Choice
Energy Efficiency and Long-Term Savings
The Sharp ZU1 is not just any heat pump; it’s equipped with the latest inverter technology, which adjusts the compressor’s speed to meet the precise heating or cooling demands. This means the unit doesn’t constantly turn on and off, saving energy and significantly reducing electricity bills. Its SEER rating of 24.0 is among the highest available, guaranteeing that homeowners can enjoy energy efficiency without sacrificing performance.
Plasmacluster Technology: A Breath of Fresh Air
Sharp is known for its Plasmacluster technology, which is a unique air purification system that goes beyond simply cooling or heating a space. This system helps to remove allergens, mold, and even viruses from the air, ensuring that the indoor environment is not only comfortable but also healthier for the homeowner and their family. In homes where indoor air quality is a concern, such as those with pets or respiratory sensitivities, the Sharp ZU1 makes a significant difference.
Quiet Operation for a Peaceful Home
One of the standout features of the Sharp ZU1 is its quiet operation. With a sound pressure level of just 23 dB(A) indoors, it’s one of the quietest models on the market. For this installation, that was a particularly important consideration, given its placement near the staircase, where noise could easily carry through the house. The homeowner was thrilled with how quiet the system was, even when running at full capacity.
The LogisVert Grant: A Game-Changer for Quebec Homeowners
A big selling point for the Sharp ZU1 is its eligibility for the $2,172 LogisVert grant, offered by Hydro-Québec. This is the highest grant available for a mini split in its class and provides a significant financial incentive for homeowners who are looking to improve their home’s energy efficiency. The Sharp ZU1 is a perfect match for this program due to its top-tier energy efficiency and eco-friendly refrigerant.
How to Qualify for the Grant
To qualify for the LogisVert grant, the installation must meet specific energy efficiency requirements, and the homeowner needs to ensure that the unit is installed by a certified professional. Our team at AirGreen specializes in helping clients navigate the application process, ensuring that they get the maximum available incentives for their HVAC upgrades.

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.
