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.

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.
Bringing Year-Round Comfort to Senneville with an 18,000 BTU Sharp Mini Split
When it comes to efficient home comfort solutions in Montreal and surrounding areas, our recent installation in Senneville stands out as a prime example of how we combine quality, expertise, and cutting-edge technology to enhance indoor living environments. We recently installed a Sharp ZU1 wall-mounted mini split heat pump, a high-performance model renowned for its 18,000 BTU cooling capacity and impressive heating performance down to -27°C. This installation is not just about keeping spaces comfortable year-round—it’s about optimizing indoor air quality and delivering energy savings in a package that is both quiet and smart.
Why the Sharp ZU1 Stands Out
The Sharp ZU1 series is an extraordinary choice for those looking for reliable HVAC solutions in the harsh Canadian climate. With a cooling capacity of 18,000 BTU and heating capabilities down to -27°C, this model ensures comfort regardless of season or weather. Equipped with Energy Star® certification and a remarkable 24.0 SEER efficiency rating, this system not only provides exceptional temperature control but does so efficiently. For homeowners in Senneville, this means lower energy bills without compromising on comfort.
Key Features of the Sharp ZU1 Heat Pump
- Energy Efficiency: 24.0 SEER rating for significant energy savings.
- Extended Warranty: 10 years on the compressor, parts, and labor, ensuring peace of mind.
- Quiet Operation: With sound levels as low as 25 dB(A) indoors, you won’t even notice it’s there.
- WiFi Compatibility: Full control from your smartphone, giving flexibility to adjust settings remotely.
The Installation Process: Precision and Care
For this installation, our team worked meticulously to ensure that every step met the high standards that define AirGreen’s reputation. Installing a ductless mini split requires precision, particularly when positioning the indoor and outdoor units to maximize efficiency and airflow. In Senneville, we were able to mount the interior unit in a central location, optimizing air circulation throughout the space while maintaining an aesthetic that complements the home’s interior design.
The exterior unit was carefully positioned to balance accessibility for maintenance with an unobtrusive profile, ensuring it doesn’t detract from the home’s exterior appeal. Our technicians took special care to integrate the unit’s R-32 refrigerant piping and ensure all wiring was safely routed and concealed, giving the installation a clean, professional look.
Advantages of the Sharp ZU1 System in Senneville’s Climate
Living in Senneville means experiencing everything from hot summers to freezing winters. The Sharp ZU1’s heating capacity makes it ideal for this climate, where temperatures can plunge dramatically. The unit’s Plasmacluster technology goes beyond mere heating and cooling, actively purifying the air by releasing ions that neutralize airborne bacteria, viruses, and allergens—perfect for households with sensitivities or those who prioritize air quality.
Reliable Heating in Extreme Cold
The Sharp ZU1 doesn’t just maintain warmth; it excels in sub-zero temperatures, providing steady, reliable heating even at -27°C. This feature is essential for our Quebec customers, as many conventional units lose efficiency or fail to operate in such extreme cold. The HOT GAS PIPE system in the ZU1 prevents the exterior unit from freezing, ensuring continuous heating without performance dips.
Advanced Air Purification with Plasmacluster Technology
Air quality is crucial, and Sharp has integrated its Plasmacluster Ion Technology into this model, which not only heats and cools but also purifies the air by eliminating odors, bacteria, and viruses. For the residents of Senneville, this means breathing cleaner, fresher air every day.
Why This Installation is Eligible for the Highest LogisVert Grant
An additional benefit of this particular Sharp ZU1 installation is its eligibility for a $2,640 LogisVert Grant from Hydro-Québec, the highest grant available in the 18,000 BTU category. This grant helps homeowners offset the initial investment, making high-efficiency systems like the ZU1 more accessible. With the grant, this installation becomes not just a comfort upgrade but a financially savvy choice that contributes to Quebec’s energy efficiency goals.
Dimensions and Technical Specifications
The Sharp ZU1 is designed to fit seamlessly into residential spaces, with dimensions that make it suitable for various indoor settings. Here’s a quick look at the technical specifications for those who appreciate the details:

Installation Challenges and Solutions
Every installation presents unique challenges, and this project in Senneville was no exception. The location required careful consideration of noise levels, airflow direction, and placement to avoid any interference with the home’s existing structure and design. Our team coordinated with the homeowners to ensure the outdoor unit was positioned to minimize visibility while still being accessible for future maintenance. The indoor unit’s placement required precision to balance effective air distribution without compromising the room's aesthetic.

What would it look like at your place?
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.

Your own project, step by step
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.
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.
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.
