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 Breath of Fresh Air: Introducing the Sharp ZU1 Mini Split in Ville Mont-Royal
In the heart of Ville Mont-Royal, AirGreen proudly installed a Sharp ZU1 mini split heat pump, offering unparalleled comfort and energy efficiency at our client’s home. This installation not only brings advanced climate control technology but also improves indoor air quality, making it an ideal choice for environmentally conscious homeowners.
Outstanding Features of the Sharp ZU1 Mini Split
The Sharp ZU1 mini split is a powerful 18,000 BTU unit equipped with cutting-edge features that set it apart from traditional HVAC systems. Let’s explore what makes this system so special:
1. High Efficiency and Eco-Friendly Design
The Sharp ZU1 boasts an impressive SEER rating of 24.0, ensuring maximum energy efficiency. It uses the latest generation refrigerant R-32, known for its low global warming potential, thereby reducing the system’s environmental footprint. This eco-friendly feature aligns perfectly with the new Quebec government energy efficiency standards set for 2025.
2. Advanced Air Purification with Plasmacluster Technology
What truly sets the Sharp ZU1 apart is its unique Plasmacluster technology. This feature releases ions that neutralize airborne viruses, bacteria, and mold, providing a healthier living environment. It’s not just a heat pump; it’s a complete air purification system that combats allergens and unpleasant odors, ensuring fresh air throughout the home.
3. Innovative Airflow Control with the Coanda Effect
The Coanda airflow control is an engineering marvel that uses the natural tendency of air to adhere to surfaces. This technology ensures even temperature distribution in rooms, eliminating hot or cold spots. The long diffuser vane further enhances air distribution, capable of directing airflow up to 15 meters, making it ideal for open spaces or homes with high ceilings.
4. Quiet and Comfortable Operation
Noise levels are a crucial factor for any HVAC system. The Sharp ZU1 operates quietly, with an indoor sound pressure level ranging from 25 to 49 dB(A) and an outdoor level of 52 dB(A). This low noise level ensures comfort is not compromised by disruptive sounds, providing a peaceful indoor environment.
Comprehensive Warranty and Reliability
A remarkable feature of the Sharp ZU1 is its extended warranty coverage—10 years for the compressor, parts, and labor, all provided directly by the manufacturer. This warranty highlights the product’s durability and Sharp’s confidence in its performance.
Smart Connectivity for Modern Living
The Sharp ZU1 is equipped with smart connectivity features, including WiFi control. Homeowners can manage the system remotely via a smartphone app, adjust settings, monitor energy consumption, and even receive notifications about maintenance needs or system status. This level of control ensures optimal efficiency and enhanced convenience.
Installation Overview
During the installation in Ville Mont-Royal, our AirGreen team faced a unique challenge: integrating the new system into a home with existing architectural constraints, such as a skylight. Our experienced technicians expertly navigated these challenges, ensuring a smooth and efficient Sharp ZU1 installation.
The system’s sleek design and compact dimensions (41.42 x 9.80 x 12.44 inches for the indoor unit) make it an ideal space-saving choice, enhancing aesthetics without overpowering the room’s decor. The use of high-quality materials and precise installation techniques guarantees the system will operate optimally for many years.

The big day, step by step
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 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.
