A Game-Changing HVAC Installation in the Heart of West Island
At AirGreen, we are committed to delivering top-quality HVAC installations that elevate comfort while ensuring peak energy efficiency. Our latest project in West Island is a testament to this mission. We recently installed a cutting-edge SHARP ZU1 18,000 BTU Mini Split Heat Pump, and the experience was as satisfying as the climate control results it brought to our client's home. Here’s a deeper dive into what makes this installation exceptional.
The Project: Bringing Comfort to West Island
Nestled in the scenic suburbs of West Island, our client’s home needed a modern HVAC upgrade to handle Montreal's ever-fluctuating weather. From hot, humid summers to frigid winters, the SHARP ZU1 Mini Split Heat Pump was the perfect choice to create a sanctuary of perfect temperatures year-round. With a heating capacity that performs reliably down to -27°C, this unit is a powerhouse of efficiency and dependability.
Why the SHARP ZU1 Mini Split?
When it comes to performance, the SHARP ZU1 model leaves no room for compromise. Let’s highlight what makes this unit stand out:
- Impressive Efficiency: With an exceptional 24.0 SEER rating, the SHARP ZU1 maximizes energy savings, keeping utility bills low while ensuring optimal comfort.
- Extreme Cold Capability: This heat pump doesn’t just keep you cool in the summer; it also provides reliable heating even in harsh temperatures, performing exceptionally at -27°C. Montreal winters have met their match!
- Silent Operation: The indoor unit operates as quietly as 25 dB(A), creating a serene environment. Even the outdoor unit stays remarkably silent at 52 dB(A), perfect for neighborhood peace.
Installation Details That Matter
Precision Engineering and Placement
Every HVAC installation comes with its own set of challenges, and this one was no exception. Our experienced technicians carefully mounted the indoor unit, measuring 41.42 inches in length, 9.8 inches in depth, and 12.44 inches in height, to optimize airflow and blend seamlessly with the room's interior design. The outdoor unit, a sturdy and compact 33.47 x 13 x 27.94 inches, was strategically placed to maximize performance and minimize exposure to the elements.
We paid close attention to every detail, including the efficient routing of the 1/4" and 3/8" pipes. Our team ensured that the installation maintained a clean, professional look, with minimal visual impact. The system’s R-32 refrigerant is environmentally friendly, aligning with our commitment to sustainable practices.
Maximizing Energy Rebates
One of the most compelling features of the SHARP ZU1 is its eligibility for the $2,640 LogisVert Grant from Hydro-Québec. This grant is the highest available for an 18,000 BTU heat pump, making it a financially smart investment for our client. Our team guided the homeowner through the rebate application process, ensuring a smooth experience.
The Advanced Technology of SHARP
Plasmacluster Ion Technology
An integral feature of the SHARP ZU1 is its Plasmacluster Ion Technology. This innovative system purifies the air by eliminating airborne bacteria, viruses, and allergens, creating a cleaner and healthier indoor environment. Whether it’s pet odors or everyday pollutants, this heat pump keeps the air fresh and breathable.
Smart Home Integration
For the tech-savvy homeowner, the SHARP ZU1 offers built-in Wi-Fi, allowing seamless control through a smartphone app. The convenience of adjusting temperatures from anywhere makes this unit a perfect fit for the modern lifestyle. Additionally, energy usage tracking enables the homeowner to monitor and optimize electricity consumption.
Client Satisfaction: A Priority for AirGreen
Our clients were thrilled with the results. Not only did the SHARP ZU1 Mini Split significantly improve their indoor comfort, but they were also delighted by the sleek, minimalistic design that complemented their home’s aesthetic.

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.
