A Top-Quality Installation Tailored for Kirkland’s Needs
When it comes to optimizing indoor comfort for our clients, we leave no detail unchecked. Our recent project in Kirkland was no exception. We had the pleasure of installing the state-of-the-art SHARP ZU1 Mini Split Heat Pump, a true game-changer in the world of HVAC. This isn’t just any installation—it’s a testament to precision, efficiency, and our commitment to excellence.
Why the SHARP ZU1 Stands Out
The SHARP ZU1 Mini Split Heat Pump isn’t your average unit. It comes equipped with 18,000 BTUs of cooling capacity and the ability to keep spaces warm even in frigid conditions as low as -27°C. Imagine cozy warmth on the coldest Kirkland mornings or a blissfully cool atmosphere during summer's peak. This model is more than ready to handle the fluctuations of our challenging Canadian climate.
Key Features that Make a Difference
- Energy Efficiency: With an impressive 24.0 SEER, this unit ensures that energy bills stay manageable. Homeowners will appreciate the reduced environmental impact and the increased savings over time.
- Plasmacluster Technology: Known for purifying the air, this feature neutralizes bacteria, viruses, mold, and allergens, creating a healthier environment for the entire family. It’s like breathing in the clean, crisp air of the countryside—right from your living room.
- Silent Operation: Noise shouldn’t be a sacrifice you make for comfort. With an interior sound pressure level as low as 25 dB(A) (think the gentle rustling of leaves), you can enjoy peace and quiet without even realizing the unit is working.
- WiFi Connectivity: Control at your fingertips—whether you're at home or halfway around the globe. You can easily adjust the temperature and set schedules using your smartphone.
The Installation Journey
A Backstory Worth Sharing
Our journey to installing this unit began with a call from the homeowners in Kirkland. They had grown tired of inconsistent heating and cooling and wanted a reliable system that was also environmentally friendly. They had heard great things about the SHARP ZU1 and were particularly interested in its Energy Star® certification and ability to provide comfort even during harsh winters.
Assessing the Space
Before installation, we conducted a thorough assessment of the space. Given the home's open floor plan, we needed a unit that could deliver consistent airflow while remaining unobtrusive. Our technicians carefully planned the positioning of the indoor unit to maximize its efficiency and ensure even distribution of air throughout the room.
Installation Details
- Interior Unit: The sleek AY-XP18ZU1 was mounted high on the wall, blending seamlessly with the decor. Its compact dimensions (41.42 x 9.80 x 12.44 inches) made it perfect for this room, providing powerful performance without taking up valuable space.
- Exterior Unit: The AE-X18ZU1 was securely placed outside, designed to withstand Kirkland’s elements. Its compact and robust build (33.47 x 13 x 27.94 inches) ensures long-term durability, even in challenging weather conditions.
Maximizing Efficiency with Precision
We used high-quality piping (1/4 - 3/8 inches) and ensured optimal placement to minimize energy loss. The unit’s R-32 refrigerant, known for its lower global warming potential, was another eco-friendly aspect that the homeowners appreciated. Additionally, we took great care to ensure that all wiring and connections were expertly concealed, maintaining the home’s aesthetic.
LogisVert Grant: A Significant Benefit
One of the standout features of this installation is that the SHARP ZU1 qualifies for the highest LogisVert grant available—up to $2,640. We guided the homeowners through the process, ensuring they could take full advantage of this incredible incentive.
Benefits of Choosing AirGreen for Your HVAC Needs
At AirGreen, we take pride in our meticulous attention to detail and customer satisfaction. Our team works tirelessly to ensure each project is completed to the highest standard, and this installation in Kirkland was no exception. We don’t just install machines; we transform living spaces into havens of comfort and well-being.
A Bright Future with SHARP Technology
Choosing the SHARP ZU1 Mini Split Heat Pump is about investing in quality, sustainability, and future-proof comfort. With features like motion sensors for intelligent airflow direction, energy-saving modes, and a design that prioritizes user convenience, this unit brings unparalleled value to any home.
How to Maintain Your New Heat Pump
We emphasize the importance of regular maintenance to keep the unit functioning at its best. A simple deep clean every 12 to 18 months can significantly extend its lifespan and improve air quality. We offer professional cleaning services tailored to your HVAC needs to ensure longevity and efficiency.
Why This Installation Is a Game-Changer for Our Kirkland Clients
This isn’t just another heat pump installation. It’s a strategic upgrade designed to offer maximum comfort and energy savings. From the ultra-efficient 24.0 SEER rating to the peace of mind provided by a 10-year warranty on parts, labor, and the compressor, the SHARP ZU1 truly redefines what a premium HVAC system should be.
Whether you’re facing Kirkland’s frosty winters or humid summers, this heat pump has you covered. And remember, when you choose AirGreen, you’re choosing unmatched expertise, friendly service, and a company that genuinely cares about your comfort.
The job tools
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.
How the job unfolds
The main steps of this kind of job at AirGreen. Every house has its quirks: the estimate brings them out.
We look at the room, the outside wall, the line route and where the outdoor unit will go. That is where the capacity gets chosen.
Model, capacity and price, in writing. We also check whether the model qualifies for assistance programs.
Floors and furniture protected, wall plate position marked level, wall opening located.
A single opening, with the slope the drain needs to flow outside.
Set on a stand raised above the snow, with the clearances the manufacturer requires.
Connected, insulated and protected. The opening is then sealed against water, cold air and insects.
A dedicated circuit and an accessible disconnect near the outdoor unit.
Leak test, vacuum, then start-up and a check of heating and cooling.
Remote, modes, filters: we show you the essentials before we leave.

What we check on a job like this one
Each number is a point we check on site. Switch between summer and winter to watch air and heat move.
In summer, the outdoor unit rejects the house's heat outside.
Generic illustration of this type of installation, not a survey of this job site. Tap a number.
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.
Is your home ready?
Check what applies at your place. A "no" is not a refusal: it is what we sort out during the estimate.
Good habits, once the unit is in place
Six simple habits that keep the unit going. Your list stays on this device.
What to do, season by season
Three habits per season for this unit. They take a few minutes and prevent many calls.
- Clean the indoor unit's filters.
- Clear leaves and debris left on the outdoor unit by winter.
- Test cooling before the first hot days.
- Clean the filters more often when the unit runs a lot.
- Keep plants away from the outdoor unit.
- Check that no water drips from the indoor unit.
- Rake the leaves around the outdoor unit.
- Test heating before the first cold days.
- Book periodic maintenance before winter.
- Keep snow away from the stand and the front of the unit.
- Let the unit defrost: it is normal.
- Never hit the ice on the fins; call us if the unit stays iced up.
The right pages, at the right time
Four statements: true or false?
It all comes down to details you have just seen.
1. In heating mode, the outdoor unit can produce water.
During defrost cycles. That water must drain away without forming ice.
2. You pick the capacity with a simple square-footage rule.
Windows, insulation, orientation and how the room is used all count. Capacity is chosen on site.
3. A multi-zone connects several indoor heads to a single condenser.
One head per room, all on the same condenser. Each room keeps its own temperature.
4. The disconnect can sit behind the patio furniture.
It must stay accessible: it is what shuts the unit off for service.
