Experience Unparalleled Comfort with the SHARP ZU1 Heat Pump Installation
At AirGreen, we recently completed the installation of a SHARP ZU1 15,000 BTU Wall-Mounted Heat Pump in a beautiful residence located in Anjou, and the results were nothing short of spectacular. This advanced heat pump, known for its exceptional performance and energy efficiency, now brings year-round comfort to its new owners while seamlessly blending with their home environment. Here’s a closer look at this project and why the SHARP ZU1 is the perfect choice for Quebec’s challenging climate.
Why the SHARP ZU1 Stands Out
The SHARP ZU1 is no ordinary heat pump. It’s designed to handle the toughest winters and hottest summers with ease. With a cooling capacity of 15,000 BTU and the ability to provide heating at temperatures as low as -27°C, this system ensures comfort no matter the season. But that’s just the beginning—let’s dive into the details.
Key Features of the SHARP ZU1
- Energy Efficiency: Boasting an impressive 24.0 SEER, this heat pump is Energy Star® certified, reducing energy costs while maintaining top-notch performance.
- Innovative Refrigerant: The ZU1 uses the eco-friendly R-32 refrigerant, which not only improves efficiency but also has a significantly lower environmental impact compared to traditional refrigerants.
- Ultra-Quiet Operation: With a sound pressure level of just 23 dB(A) indoors, the ZU1 operates so quietly that you might forget it’s even running.
- Plasmacluster Technology: This unique air purification system neutralizes airborne bacteria, viruses, and allergens, ensuring cleaner, healthier air for your family.
The Installation Journey in Anjou
The installation process was both meticulous and rewarding. The AirGreen team worked closely with the homeowners to ensure the system was perfectly positioned to optimize airflow and maintain the home’s aesthetic appeal. The indoor unit, measuring 41.42 x 9.80 x 12.44 inches, was mounted in the living area, providing discreet yet efficient performance. Meanwhile, the compact outdoor unit, at just 30.72 x 10.59 x 21.25 inches, was securely placed to ensure maximum durability and minimal noise.
Overcoming Challenges
One unique aspect of this installation was the home’s layout, which required strategic planning to ensure uniform temperature distribution across all rooms. Leveraging the SHARP ZU1’s Coanda airflow technology, we achieved a seamless balance of warmth and cooling throughout the space, eliminating hot and cold spots.
Benefits for the Homeowners
Government Grants
One of the highlights of this installation is that the SHARP ZU1 qualifies for the $2,172 LogisVert Grant, the highest grant available for any 15,000 BTU heat pump. This significant rebate not only makes the system more affordable but also underscores its superior energy efficiency.
Year-Round Comfort
Thanks to its cutting-edge features, the ZU1 will keep the homeowners comfortable through Quebec’s unpredictable weather. Whether it’s the scorching heat of summer or the frigid depths of winter, this system delivers reliable performance.
Healthier Indoor Air
The Plasmacluster technology ensures that the air inside the home is free from pollutants, providing peace of mind for the homeowners, especially during allergy season.

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.
