A Reliable Solution for Year-Round Comfort
When it comes to home comfort, AirGreen never settles for anything less than exceptional. Our latest installation in Châteauguay features the SHARP ZU1 Mini Split Heat Pump, a cutting-edge unit that promises energy efficiency and comfort, even in the harshest weather conditions. From keeping things cool in the sweltering summer to ensuring warmth during frigid winters, this system stands out for its performance and advanced technology.
Why SHARP ZU1?
The SHARP ZU1 Mini Split Heat Pump is not just any HVAC unit; it’s an 18,000 BTU powerhouse equipped to handle temperatures as low as -27°C. Perfect for Quebec’s unpredictable climate, it offers the best of both worlds: a robust cooling capacity and reliable heating. Let's dive into the details of this innovative system and our meticulous installation process.
The Châteauguay Installation: A Perfect Fit
Location: Nestled in the picturesque suburbs of Châteauguay, this installation had its unique challenges. The property required a discreet, yet highly functional setup, and we were determined to deliver.
Machine Type: We installed a ductless, wall-mounted SHARP ZU1 Mini Split Heat Pump, chosen for its sleek design and powerful performance. The 18,000 BTU capacity ensures every corner of the home remains comfortable, whether it’s a sizzling July afternoon or a freezing January night.
Grant Eligibility: Homeowners will be delighted to learn that this model qualifies for the highest Hydro-Québec LogisVert grant of $2,640. This makes it not only an environmentally responsible choice but also a budget-friendly investment.
Advanced Features of the SHARP ZU1 Mini Split Heat Pump
1. Superior Heating and Cooling
The SHARP ZU1 handles temperatures down to -27°C with ease, making it an ideal choice for extreme weather conditions. Unlike conventional heat pumps that struggle in severe cold, this model maintains efficiency, delivering warmth when it’s needed the most.
2. Plasmacluster™ Technology
One of the most impressive features is the Plasmacluster™ air purification. By releasing positive and negative ions, it neutralizes airborne bacteria, viruses, and mold, ensuring the air quality remains top-notch. This makes the unit a great choice for families concerned about indoor air health.
3. Energy Efficiency at Its Best
With a 24.0 SEER rating, the SHARP ZU1 is designed for maximum energy savings. Homeowners can rest assured knowing they are reducing their energy consumption and their environmental footprint. Moreover, the R-32 refrigerant is eco-friendly, boasting a lower global warming potential than older refrigerants.
Our Installation Process
1. Assessment and Customization
Before installation, we performed a comprehensive assessment of the property. We identified the optimal location to maximize airflow while minimizing noise. Our team ensured that the system’s placement would blend seamlessly into the home's architecture.
2. Precision Installation
Our technicians mounted the interior unit at a strategic height, ensuring balanced air distribution. The exterior unit, with its robust construction, was installed securely on a custom stand to protect it from snow accumulation and heavy rainfall. The SHARP ZU1’s low 52.0 dB(A) noise level makes it one of the quietest systems available, an essential feature for maintaining neighborhood peace.
3. Durability and Longevity
We paid special attention to the durability of this installation. By using high-quality insulation and weather-resistant materials, we guaranteed that the system would withstand harsh conditions. We also provided guidance on routine maintenance to ensure optimal performance.

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.
