A Cutting-Edge Installation Designed for Comfort and Efficiency
At AirGreen, we take immense pride in delivering advanced HVAC solutions tailored to the unique needs of our clients. Our recent installation of the 18,000 BTU SHARP ZU1 Wall-Mounted Heat Pump in Vaudreuil demonstrates our commitment to innovation, sustainability, and customer satisfaction. This energy-efficient mini-split system is equipped with the latest technologies, including Plasmacluster air purification, Coanda airflow control, and the eco-friendly R-32 refrigerant. Here’s the story behind this remarkable project.
The Client’s Vision: Efficiency Meets Elegance
Our client in Vaudreuil sought a reliable and eco-conscious solution for year-round comfort. With Québec’s frigid winters and warm summers, the goal was clear: a heat pump that could handle extreme temperatures without compromising on efficiency. After evaluating several options, the SHARP ZU1 emerged as the perfect match. Not only does this model offer exceptional performance at temperatures as low as -27°C, but it also qualifies for the $2,640 LogisVert Grant—the highest grant available for an 18,000 BTU system in Québec.
Why the SHARP ZU1 Stands Out
Unmatched Heating and Cooling Capacities
- Cooling Power: 18,000 BTU
- Heating Power: Reliable performance even at -27°C
- Efficiency: An impressive 24.0 SEER, ensuring lower energy consumption.
Innovative Technologies for Modern Comfort
- Plasmacluster Air Purification
- Neutralizes airborne viruses, allergens, and mold.
- Eliminates unpleasant odors, ensuring fresh indoor air.
- Coanda Airflow Control
- Redirects air along walls and ceilings for uniform temperature distribution.
- Prevents direct airflow on occupants, enhancing comfort.
Eco-Friendly R-32 Refrigerant
This cutting-edge refrigerant reduces greenhouse gas emissions and energy consumption by approximately 10%. It aligns with our client’s desire for a sustainable HVAC solution while meeting 2025 energy efficiency standards.
The Installation Process: Precision and Care
Step 1: Site Assessment
Our team began with a comprehensive assessment of the Vaudreuil property to determine the optimal placement for the indoor and outdoor units. The goal was to maximize efficiency while blending seamlessly with the home’s aesthetics.
Step 2: Installing the Indoor Unit
The sleek and compact interior unit, measuring 41.42 x 9.80 x 12.44 inches, was mounted on the living room wall. Its modern design complements the décor, while the 25-49 dB(A) noise level ensures whisper-quiet operation.
Step 3: Positioning the Outdoor Unit
The exterior compressor, protected by an anti-corrosive coating, was strategically installed to ensure durability against Québec’s harsh winters. With dimensions of 33.47 x 13 x 27.94 inches, the unit occupies minimal space without sacrificing performance.
Step 4: Ensuring Connectivity and Efficiency
- WiFi-Enabled Control: The SHARP ZU1’s smart connectivity allows the homeowner to monitor and adjust settings via a smartphone app.
- Energy Monitoring: Real-time data on energy consumption helps optimize usage and reduce costs.
Key Benefits of This Installation
Enhanced Comfort
The combination of Plasmacluster technology and Coanda airflow creates a healthier, more comfortable living environment. Whether heating during a snowstorm or cooling during a summer heatwave, the SHARP ZU1 delivers consistent performance.
Energy Savings
With its inverter technology and high SEER rating, this heat pump minimizes energy waste. The client can enjoy lower utility bills without compromising on comfort.
Environmental Responsibility
By using R-32 refrigerant, the SHARP ZU1 significantly reduces its carbon footprint. This aligns with both the client’s values and AirGreen’s commitment to sustainability.
Customer Feedback: A Job Well Done
Our client in Vaudreuil couldn’t be happier with their new SHARP ZU1 heat pump. They were particularly impressed by its quiet operation and the noticeable improvement in air quality, thanks to Plasmacluster technology. The ability to control the system remotely via the SHARP app added an extra layer of convenience.

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.
