Efficient Heating and Cooling Meets Modern Design: A Unique Installation Story
When it comes to ensuring year-round comfort and energy efficiency, choosing the right heat pump system is crucial. At AirGreen, we pride ourselves on offering top-notch solutions tailored to our customers' specific needs. Recently, we completed the installation of a Sharp ZU1 12,000 BTU Wall-Mounted Heat Pump in a charming home located in Candiac, a serene community on the South Shore of Montreal. This installation was a true testament to how advanced HVAC technology can seamlessly integrate into everyday life while delivering optimal performance.
Why the Sharp ZU1 is Perfect for Candiac Homes
The Sharp ZU1 12,000 BTU Wall-Mounted Heat Pump is a standout choice for homes in Candiac for several reasons. Designed to thrive in extreme temperatures, it delivers dependable heating even when the mercury plunges to an icy -27°C. This model isn't just about staying warm during harsh winters; it also offers superior cooling performance during those sweltering summer days.
Equipped with R-32 refrigerant, the ZU1 is both environmentally friendly and highly efficient. It meets stringent energy standards, making it an excellent choice for homeowners looking to reduce their carbon footprint and energy bills. Additionally, the system boasts a remarkable 22.0 SEER rating, ensuring top-tier performance year-round.

The Installation Process: Precision and Care
At AirGreen, we believe every installation tells a story. For this project, our team meticulously planned and executed the installation to ensure maximum efficiency and aesthetic appeal. The indoor unit, with its sleek and compact design, was strategically positioned in a high-traffic area of the home. Measuring just 34.61 x 9.02 x 11.38 inches, the unit fits perfectly above the back door, blending seamlessly with the home’s interior design.
The outdoor compressor, equally compact at 30.72 x 10.59 x 21.25 inches, was placed in a location optimized for airflow and ease of maintenance. To guarantee long-term reliability, we utilized high-quality 1/4 - 3/8 inch pipes and ensured proper drainage with the compressor’s multiple drainage holes. These small but essential details are what set our installations apart.
Advanced Features That Enhance Comfort
The Sharp ZU1 isn’t just a mini split heat pump; it’s a marvel of modern HVAC engineering. Here are some key features that make it a top choice:
- Plasmacluster Technology: This unique air purification system eliminates airborne viruses, mold, and allergens, ensuring healthier indoor air quality for the homeowners.
- Coanda Airflow Control: The system intelligently directs airflow along walls and ceilings, creating a uniform temperature throughout the space without uncomfortable drafts.
- Whisper-Quiet Operation: With an interior sound level as low as 23 dB(A), the system operates so quietly that you’ll forget it’s even there.
- WiFi Connectivity: The integrated WiFi feature allows homeowners to control the system remotely, providing convenience and energy savings.
- Energy Star Cold Climate Certification: Designed to excel in Quebec’s extreme weather, the ZU1 offers efficient heating even in freezing temperatures.
Eco-Friendly and Budget-Friendly
One of the standout features of this installation is the system’s eligibility for the $1,740 LogisVert Grant by Hydro-Québec. This incentive not only helps offset the initial investment but also highlights the system’s energy efficiency and environmental benefits. The R-32 refrigerant used in the ZU1 has a lower global warming potential, making it a responsible choice for environmentally conscious homeowners.
Customer Satisfaction: The AirGreen Difference
For our clients in Candiac, this installation was more than just an upgrade—it was a step toward a more comfortable, healthier, and energy-efficient home. The homeowners were particularly impressed by the system’s ability to maintain consistent temperatures throughout the house, even during a recent cold snap. They also appreciated the sleek design of the indoor unit, which complemented their modern interior decor.
At AirGreen, customer satisfaction is at the heart of everything we do. From the initial consultation to the final walkthrough, we ensure that every detail is addressed. Our team took the time to explain the system’s features, including how to use the WiFi app for remote control and monitoring.

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.
