A Tailored Comfort Solution for Verdun Residents
At AirGreen, we take pride in bringing efficient and reliable HVAC solutions to homes across Montreal, Laval, Longueuil, the North Shore, and the South Shore. Our recent project in Verdun showcases the seamless integration of advanced technology and thoughtful installation to deliver year-round comfort. This installation features the SHARP ZU1 mini split heat pump, a highly efficient 18,000 BTU unit, equipped to withstand the harsh Canadian climate.
Why the SHARP ZU1? A Perfect Fit for Verdun Homes
The SHARP ZU1 series is known for its high-performance heating and cooling capabilities. This ductless mini split system is ideal for spaces where traditional ductwork isn't feasible. With a cooling capacity of 18,000 BTU and a heating capacity that performs efficiently down to -27°C, the ZU1 offers versatile climate control throughout the year. Its sleek design allows it to blend seamlessly into any home decor, as seen in our recent installation in Verdun.
A Closer Look at the Installation
Our team meticulously planned and executed the installation of the SHARP ZU1 mini split heat pump in this Verdun residence. Here’s a breakdown of the key aspects that made this installation special:
- Location: Verdun, a charming neighborhood known for its cozy homes and vibrant community. Our installation had to ensure minimal disruption while providing maximum comfort.
- Equipment: SHARP ZU1 heat pump, a top-tier choice for homeowners looking for efficiency and durability. The 18,000 BTU capacity ensures that this system can handle the fluctuating temperatures of Montreal's seasons.
- Grant Eligibility: This installation qualifies for a $2,640 LogisVert Grant by Hydro-Québec—the highest grant available for heat pumps in the 18,000 BTU category. This grant makes upgrading to a more energy-efficient HVAC system both practical and economical.
- Advanced Technology: Equipped with R-32 refrigerant, known for its environmental benefits and improved energy efficiency, the SHARP ZU1 provides effective cooling in summer and consistent heating even on the coldest winter days.

Attention to Detail: Ensuring Optimal Performance
Precision Placement for Maximum Efficiency
The interior unit, model AY-XP18ZU1, was installed in the living area, providing even airflow throughout the space. With dimensions of 41.42 x 9.80 x 12.44 inches, it fits perfectly above the couch, offering a discreet yet powerful presence. This placement allows for a consistent temperature without cold or hot spots, enhancing the overall comfort of the room. The outdoor unit, model AE-X18ZU1, was strategically placed to ensure efficient heat exchange and quiet operation, with a sound level of 52.0 dB(A), ensuring peace and quiet for the neighborhood.
Sound Control for a Peaceful Home
The SHARP ZU1 mini split unit is designed with quiet operation in mind. Inside, it operates at 25 to 49 dB(A), making it ideal for a serene living environment. Whether the homeowners are enjoying a movie night or having a peaceful evening, the SHARP ZU1 operates without disturbing background noise.
The SHARP Advantage: Efficiency Meets Reliability
Energy Efficiency and Environmental Responsibility
This Energy Star® rated unit boasts an impressive 24.0 SEER, making it one of the most energy-efficient options on the market. Using R-32 refrigerant, which has a lower Global Warming Potential (GWP) compared to other refrigerants, the SHARP ZU1 aligns with environmental goals while keeping operational costs low.
Durability in Montreal's Harsh Winters
Montreal winters can be notoriously harsh, but with the SHARP ZU1's robust design, homeowners in Verdun can count on reliable heating even when temperatures plummet to -27°C. This makes it a standout choice for those looking to invest in a heat pump that is built to last. The 10-year warranty on the compressor, parts, and labor further enhances the long-term value of this installation.

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.
