Efficient Heating and Cooling for Quebec’s Extreme Weather
In the scenic neighborhood of Town of Mount Royal (TMR), our team at AirGreen recently completed an installation that exemplifies our commitment to quality and reliability. The project involved setting up a 15,000 BTU Sharp ZU1 wall-mounted mini split heat pump, a top choice for homeowners across Montreal, Laval, Longueuil, the North Shore, and the South Shore. This modern, energy-efficient system is not only ideal for Quebec’s cold winters but also excels at providing cooling during the sweltering summer months.
Bringing Comfort to Every Corner of the Home
Our client in TMR needed a dependable heating solution capable of withstanding Quebec's harsh winter temperatures, which often drop well below freezing. The Sharp ZU1, with its heating capacity extending down to -27°C, easily delivers consistent warmth even under the most severe conditions. Additionally, its 24.0 SEER rating ensures optimal energy efficiency, helping to keep heating costs in check.
The Sharp ZU1 represents a new generation of heat pumps, using the eco-friendly R-32 refrigerant, known for its lower environmental impact and superior efficiency. This installation not only enhances immediate comfort but also aligns with Hydro-Québec’s sustainability goals, as it qualifies for the substantial $2,172 LogisVert Grant—the highest rebate available for a 15,000 BTU unit in the province.
Smooth and Clean Installation Process
Installing the Sharp ZU1 mini split heat pump required meticulous planning and execution. The outdoor unit was securely mounted on a durable bracket, positioned to ensure optimal airflow and minimize noise for the homeowner. The indoor unit was strategically placed to maximize airflow distribution, ensuring even heating and cooling throughout the living space. We used high-quality insulated copper pipes for efficient refrigerant flow and installed premium electrical wiring to ensure the system’s longevity.
While on-site, we took the opportunity to thoroughly clean the client’s old system. As the photos reveal, the coils of the existing unit were heavily clogged with dust and debris, impairing its efficiency. After a professional cleaning, the old system was restored to near-optimal performance. The customer was delighted with this added effort, especially since the improvement in air quality was immediately noticeable.
The Advanced Technology of the Sharp ZU1
Plasmacluster Air Purification – A Healthier Home Environment
One of the standout features of the Sharp ZU1 heat pump is its Plasmacluster air purification technology. This advanced system releases positive and negative ions into the air, neutralizing airborne contaminants such as viruses, allergens, and odors. It’s an ideal solution for families who prioritize indoor air quality, providing peace of mind that every breath taken indoors is fresh and clean.
Coanda Airflow Control – Achieving Perfect Comfort
The Sharp ZU1 also incorporates Coanda airflow control, a sophisticated feature that mimics natural air movement to evenly distribute air throughout the room. By guiding warm air downward in the winter and cool air upward in the summer, this mechanism helps maintain a consistent temperature without uncomfortable drafts. Whether you’re near the window or in a distant corner, you can count on uniform comfort in every part of your home.
Hot Gas Pipe System – Winter-Ready Performance
The ability of the Sharp ZU1 to operate efficiently down to -27°C is made possible by its patented Hot Gas Pipe system. This innovative technology circulates hot gas through the piping to prevent the outdoor compressor from freezing, ensuring reliable operation even during the coldest winter days. For homeowners in Quebec, where extreme weather is the norm, this feature is invaluable.

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.

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.

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.
