A high-end HVAC installation in Boucherville combining performance, design, and air quality
At AirGreen, our mission is to combine indoor comfort, energy efficiency, and superior air quality. We recently completed a full installation of a SHARP ZU1 18000 BTU wall-mounted heat pump in a residence located in Boucherville, on the South Shore of Montréal. This project perfectly illustrates our technical expertise and our ability to offer customized solutions to residential clients in the Montréal, Longueuil, and Laval areas.
Why choose the SHARP ZU1 heat pump?
The SHARP ZU1 series strikes the perfect balance between performance, compact design, and innovative technology. The model AY-XP18ZU1 / AE-X18ZU1, selected for this installation, is ideal for single-family homes in Quebec, especially given its ability to operate efficiently even in the harshest winter conditions.
Here are its main technical specifications:
-
Cooling capacity: 18,000 BTU/h (min-max: 6,000 - 21,600 BTU/h)
-
Heating capacity: 21,600 BTU/h (min-max: 5,500 - 25,600 BTU/h)
-
Performance at -27°C: maintains 11,500 BTU/h – ideal for Quebec’s freezing winters
-
Eco-friendly refrigerant: R-32, environmentally responsible
-
Energy efficiency: SEER 24 / HSPF up to 13
-
Exclusive technology: Plasmacluster air purification
-
Compact wall-mounted design: 41" wide indoor unit with a sleek, modern look
This ductless wall-mounted heat pump is perfectly suited for homeowners seeking both heating and cooling in a single system, without compromising on indoor aesthetics.
Installation steps in Boucherville: expertise, discretion, and efficiency
For this residential installation, our team of certified AirGreen installers visited the site to plan and optimize the placement of the wall unit, which needed to be integrated into a tight space between two utility walls.
Space assessment and strategic positioning
The indoor unit was installed on a dark grey central wall, at the ideal height to ensure even air distribution. Access to this wall was slightly limited due to a wall-mounted intercom and electrical switches. Our technicians carefully mounted the SHARP ZU1 unit without disrupting any of the existing systems.
Exterior work and wall coring
We carried out a full wall core drill through the load-bearing wall to pass the refrigerant lines, condensate drain, and electrical wiring—all while ensuring perfect airtightness and moisture sealing.
Dedicated electrical connection
The heat pump was connected to a dedicated 25 A breaker, in full compliance with the manufacturer’s specifications. An outdoor disconnect box with safety shut-off was installed near the outdoor condenser unit, allowing for easy access during maintenance or emergencies.
What makes the SHARP ZU1 stand out: comfort, health, and savings
Plasmacluster technology: for cleaner, healthier air
Exclusive to SHARP, Plasmacluster technology uses hydrogen and oxygen ions to neutralize airborne bacteria, viruses, mold, and allergens. This creates a cleaner, safer atmosphere for families, especially those with children, seniors, or pets.
High-performance heating mode down to -27°C
Thanks to its high-capacity compressor and optimized heat exchanger, this heat pump continues to deliver excellent heating performance even in the depth of winter. It’s one of the few wall-mounted heat pumps on the Quebec market certified to function efficiently down to -27°C.
Quiet and energy-efficient
The indoor unit’s sound level doesn’t exceed 28 dB in low-speed mode, making it nearly silent in operation. The inverter compressor (Inverter DC) constantly adjusts its output, allowing for significant energy savings while maintaining a steady, comfortable temperature.
Grants and ROI: the subsidized heat pump
The installation of this SHARP ZU1 18000 BTU wall-mounted heat pump in Boucherville qualifies for a LogisVert grant from Hydro-Québec, which can reach up to $1,704, depending on eligibility. This financial assistance significantly lowers the upfront cost and accelerates the return on investment for the homeowner.

At AirGreen, every installation is a unique achievement, designed to last, perform, and inspire confidence.
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.
