A Smart Investment for Comfort and Efficiency in Kirkland Homes
At AirGreen, we are committed to delivering premium HVAC solutions tailored to the diverse needs of Montrealers and the surrounding areas. Our most recent project brought us to the charming neighborhood of Kirkland, where we installed the remarkable Sharp ZU1 Wall-Mounted Heat Pump. This cutting-edge 18,000 BTU mini-split system now stands as the epitome of comfort, energy efficiency, and superior air quality for our client.
Why the Sharp ZU1 is the Ultimate Choice for Kirkland Homes
The Sharp ZU1 is not your average wall-mounted heat pump. This model integrates state-of-the-art technologies that make it a standout choice for homeowners in Kirkland and across Greater Montreal. Let’s break down what makes this machine exceptional:
Performance That Shines in All Seasons
- Heating Capacity: Performs flawlessly in extreme Quebec winters, delivering optimal heating even at temperatures as low as -27°C.
- Cooling Capacity: Boasts an impressive 18,000 BTU, ensuring effective cooling for those hot summer months.
- Efficiency: With an astounding 24.0 SEER, the Sharp ZU1 minimizes energy consumption without compromising performance.
Smart Features That Simplify Comfort
The Sharp ZU1 comes fully loaded with features that make life easier and more comfortable:
- WiFi Connectivity allows for remote operation and real-time energy monitoring.
- Energy Star® Certification ensures that the system meets the highest energy efficiency standards.
- Motion Detection Sensors notify homeowners of activity, optimizing energy use when rooms are unoccupied.
A Greener Future with R-32 Refrigerant
The Sharp ZU1 is the first to utilize the environmentally friendly R-32 refrigerant, reducing greenhouse gas emissions by up to 10% compared to traditional systems. This makes it an eco-conscious choice for Kirkland homeowners, aligning with the latest government energy efficiency regulations.
The Kirkland Installation: Details Matter
For this project, we were tasked with installing the Sharp ZU1 18,000 BTU heat pump in a family home in Kirkland. The homeowners sought an efficient solution to combat Quebec’s fluctuating temperatures while maintaining a healthy and comfortable indoor environment. Here’s how we tackled the project:
Precision Installation for Maximum Efficiency
Our expert technicians meticulously mounted the Sharp ZU1 system in the living area, ensuring optimal airflow and coverage. The installation included:
- Interior Unit (AY-XP18ZU1): Strategically placed at a height of 12.44 inches, with dimensions of 41.42 x 9.80 x 12.44 inches, allowing for efficient air distribution while blending seamlessly with the room’s décor.
- Exterior Unit (AE-X18ZU1): Installed outdoors with precise piping (1/4 – 3/8), enabling smooth refrigerant flow and energy-efficient operation. The dimensions of 33.47 x 13 x 27.94 inches ensured a compact yet powerful presence.
Plasmacluster Technology: Air Quality Like Never Before
Sharp’s Plasmacluster technology was a major selling point for this installation. It effectively neutralizes airborne viruses, bacteria, and allergens, creating a healthier environment for the family. This advanced air purification system:
- Eliminates mold and microbes.
- Fights odors and tobacco residue.
- Breaks down allergens and airborne particles.
With children and pets in the home, the homeowners appreciated the peace of mind that comes with having the cleanest indoor air possible.
Temperature Harmony with Coanda Airflow Control
One standout feature of the Sharp ZU1 is its Coanda airflow control, which directs warm or cool air along walls and ceilings. This ensures uniform temperature distribution across the room without uncomfortable drafts. With 4-way sweeping, the system adjusts airflow vertically and horizontally, providing complete comfort coverage.
Sound Levels: Whisper-Quiet Operation
Nobody wants a noisy heat pump disrupting their peaceful home. The Sharp ZU1 delivers whisper-quiet operation, with sound pressure levels of 25 dB(A) indoors and 52 dB(A) outdoors. The homeowners were particularly impressed by how silent the system was, even at full capacity.
Eligible for the Highest LogisVert Grant in Quebec
One of the most exciting aspects of this project is that the Sharp ZU1 18,000 BTU heat pump qualifies for Hydro-Québec’s LogisVert Grant. This grant provides an incredible $2,640, the highest available for any 18,000 BTU model in the province! Combined with additional federal grants of up to $5,000, the Sharp ZU1 becomes not only an energy-efficient solution but also a highly affordable investment.
A Reliable, Long-Term Solution
The Sharp ZU1 comes with an unbeatable 10-10-10 warranty:
- 10 years on the compressor
- 10 years on parts
- 10 years on labor
This extended warranty reflects Sharp’s confidence in their product’s durability, particularly in extreme climates like ours here in Quebec.

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.
