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.
A Cutting-Edge Mini Split Installation with Unmatched Energy Efficiency
At AirGreen, we recently completed the installation of a Sharp ZU1 Wall-Mounted Heat Pump at a residential property in Montréal-Nord. This particular model, with a capacity of 15,000 BTU, stands out not only for its performance but also for its eco-friendly design. As the most efficient option available in its category, it qualifies for the LogisVert Grant offered by Hydro-Québec, giving homeowners a substantial rebate of $2,172—the highest grant for any 15,000 BTU mini split system in Quebec!
Why the Sharp ZU1 is the Perfect Choice
Superior Performance for Harsh Quebec Winters
One of the most remarkable features of the Sharp ZU1 heat pump is its ability to provide consistent heating even in extreme cold temperatures. With a heating capacity down to -27°C, this mini split is built to handle Quebec’s notoriously harsh winters. Whether it's blistering cold or scorching heat, the ZU1 offers a reliable solution for maintaining indoor comfort year-round.
Energy Efficiency: A Win for Both the Environment and Your Wallet
The Sharp ZU1 is designed to be highly energy efficient, boasting an impressive 24.0 SEER rating. This means significant savings on energy bills for homeowners. Moreover, it uses the environmentally friendly R-32 refrigerant, which is more energy-efficient and has a lower environmental impact compared to older refrigerants like R-22. In short, the Sharp ZU1 doesn’t just keep your home comfortable—it also helps reduce your carbon footprint.
A Grant That’s Hard to Beat
Thanks to the LogisVert Grant, this system is highly affordable for homeowners looking to upgrade their HVAC systems. The $2,172 rebate offered by Hydro-Québec is the highest available for any 15,000 BTU mini split in the province. This means that not only are you investing in top-tier technology, but you’re also getting a significant portion of your investment back.
Cutting-Edge Features of the Sharp ZU1 Heat Pump
Plasmacluster Technology: Breathe Easier, Live Healthier
The Sharp ZU1 goes beyond temperature control—it actively improves indoor air quality. This is thanks to Sharp’s innovative Plasmacluster Technology, which purifies the air by neutralizing bacteria, viruses, mold, and even unpleasant odors. For homeowners concerned about air quality, especially in urban areas like Montréal-Nord, this technology is a game-changer.
- Neutralizes airborne viruses and bacteria
- Eliminates mold and allergens
- Reduces odors and tobacco residues
- Improves overall air quality
With the Plasmacluster Technology, you can be sure that your home’s air is as clean as it is comfortable.
Coanda Airflow: Uniform Comfort, No Drafts
One of the unique selling points of the Sharp ZU1 is its Coanda Airflow Control. This advanced airflow system ensures that air is distributed evenly throughout the room, preventing uncomfortable drafts and maintaining a balanced temperature. Whether heating or cooling, the Coanda effect directs airflow along the walls and ceilings, ensuring that every corner of the room benefits from the system’s performance.
Built to Last: Durable and Weather-Resistant
The exterior unit of the Sharp ZU1 is as tough as they come. Equipped with an anti-corrosive coating and multiple drainage holes to prevent water buildup and freezing, this unit is designed to withstand the elements. Winter after winter, this heat pump will continue to perform efficiently without requiring frequent maintenance or repairs.
Installation Challenges and Solutions: A Seamless Process
For this installation in Montréal-Nord, we had to navigate several logistical challenges, including finding the optimal placement for both the indoor and outdoor units. The home’s layout required us to carefully consider airflow paths to ensure maximum efficiency and comfort. In the end, we opted for a strategic positioning of the indoor unit that allowed for an even distribution of heat and cool air throughout the living space.
Our team also ensured that the outdoor unit was mounted securely and optimally to handle the local weather conditions, particularly the harsh winters. With our experience in HVAC installations across Montreal, Laval, Longueuil, North Shore, and South Shore, we’ve mastered the art of seamless installations, even in tricky locations.

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.
