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.

Our recent project in Repentigny showcases the installation of a Sharp ZU1 24,000 BTU heat pump, offering homeowners an efficient, environmentally-friendly solution for year-round comfort. This installation not only highlights our expertise but also aligns with our mission to deliver cutting-edge technology combined with exceptional service quality.
Bringing Comfort to Repentigny with the Sharp ZU1
The project involved the installation of the Sharp ZU1 wall-mounted heat pump under a sheltered area to protect the outdoor unit from extreme weather conditions. With the harsh Quebec winters in mind, the location was carefully chosen to ensure maximum efficiency and protection. The model's ability to function optimally at temperatures as low as -27°C makes it a perfect fit for the region’s cold climate. By installing it beneath a sturdy wooden deck, we ensured the unit stays shielded from snow accumulation, ice, and direct sunlight, enhancing its longevity and performance.
Key Features of the Sharp ZU1 Heat Pump
- Energy Efficiency: The Sharp ZU1 is a modern marvel, offering an impressive 22.0 SEER rating. Its R-32 refrigerant is more eco-friendly compared to traditional options, reducing greenhouse gas emissions and energy consumption by approximately 10%.
- Plasmacluster Technology: One of the standout features of this unit is Sharp's proprietary Plasmacluster air purification technology, which works to eliminate airborne viruses, mold, and allergens. This technology is unique to Sharp products and significantly improves indoor air quality, contributing to a healthier home environment.
- Coanda Airflow Control: Ensures even temperature distribution throughout the space. The Coanda effect gently directs airflow along walls and ceilings, providing uniform comfort without blowing cold air directly onto the occupants.
- Winter Performance: The Hot Gas Pipe system and a special defrost mode keep the unit operational even during the coldest months, minimizing heat loss and maintaining a cozy indoor environment. Multiple drainage holes prevent ice buildup, while the anti-corrosive coating extends the lifespan of the exterior components.
A Smart Choice for Homeowners: The LogisVert Grant
This installation qualifies for the LogisVert Grant by Hydro-Québec, offering homeowners in Repentigny a substantial $2,688 rebate. This is the highest grant available for a 24,000 BTU mini split heat pump, making it an economical choice for energy-conscious customers. By opting for the Sharp ZU1, homeowners not only benefit from reduced energy bills but also receive significant financial incentives that offset the installation cost.
Tailoring the Installation to the Client's Needs
Our experienced team at AirGreen paid close attention to the specific requirements of the homeowner. The installation involved careful positioning of the unit to optimize airflow while maintaining a clean, aesthetically pleasing look. We selected the ideal location to minimize noise disturbance, with the outdoor unit's sound pressure level at 53.0 dB(A)—quiet enough to operate without disturbing the peaceful environment of the residence.
To achieve optimal performance, we used high-quality 1/4 - 3/8 pipes and 220V wiring, ensuring the system operates efficiently under varying load conditions. The indoor unit's sound pressure level ranges from 25 to 49 dB(A), providing quiet comfort that suits any living space.
Smart Connectivity for Modern Living
The Sharp ZU1 offers a suite of smart features that cater to the tech-savvy homeowner.

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.
