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.
The Perfect Balance of Comfort and Efficiency: Sharp ZHU Series
At AirGreen, we pride ourselves on delivering state-of-the-art HVAC solutions that blend comfort, efficiency, and environmental responsibility. One of our latest installations, completed in Pierrefonds-Roxboro, exemplifies the high standards we set for every project. This particular job featured the Sharp ZHU 12,000 BTU Mini Split Heat Pump, an exceptional system that offers outstanding performance, especially in the challenging climate of Quebec.
Why Sharp ZHU 12,000 BTU?
When considering the perfect system for our client’s home in Pierrefonds-Roxboro, we turned to the Sharp ZHU 12,000 BTU model. This mini-split heat pump boasts an impressive heating capacity down to -27°C, making it a top choice for Quebec winters. Plus, with a 25.0 SEER efficiency, it provides optimal cooling during those hot summer months while maintaining a low environmental footprint. Sharp's focus on energy efficiency makes it eligible for significant rebates, including a $2,268 grant from the Hydro-Québec LogisVert program—one of the highest rebates available for mini splits of this size!
Installation Process: Craftsmanship Meets Innovation
We arrived on-site at our customer’s residence in Pierrefonds-Roxboro early on a crisp autumn morning, ready to transform their indoor climate. The installation was strategically planned to provide optimal airflow and efficient energy use, ensuring comfort in every corner of the home. The indoor unit was carefully mounted above a glass display cabinet, blending seamlessly into the room's decor while maximizing its cooling and heating reach.
For the outdoor unit, we selected a location that would allow the heat pump to operate efficiently without disturbing the home's aesthetic. With dimensions of 30.72 x 10.59 x 21.25, the exterior unit was compact enough to fit discreetly yet powerful enough to handle the local climate’s demands.
Energy Savings and Eco-Friendly Features
The Sharp ZHU series is a leader in environmentally friendly cooling and heating systems. This installation utilized R-32 refrigerant, which has a much lower global warming potential than traditional options like R-22, reducing its environmental impact while improving energy efficiency by up to 10%.
Our client was thrilled to learn that the ZHU series not only saves energy but also reduces greenhouse gas emissions, making it an eco-conscious choice that aligns with their values.
Performance and Quiet Operation
One of the standout features of this Sharp unit is its exceptionally low sound pressure level of 22/44 dB(A) indoors and 49 dB(A) outdoors. This means that, even during operation, the system runs quietly, ensuring the customer’s comfort is undisturbed by excessive noise.
Whether heating or cooling, the Plasmacluster technology built into the unit ensures clean, purified air by neutralizing bacteria, viruses, and allergens—an added benefit for homes with sensitive occupants.
Advanced Airflow Control: Nature-Inspired Innovation
Sharp’s dedication to innovation shines in the design of their fan blades. Drawing inspiration from nature, the indoor unit's fan blades mimic dragonfly wings, enhancing airflow by up to 30%. Similarly, the outdoor unit’s fan incorporates design elements inspired by golden eagle and albatross wings, improving power and efficiency by another 20%. These subtle, nature-inspired improvements lead to better performance and reduced energy consumption, providing a system that's as efficient as it is quiet.
Cutting-Edge Technology: Connectivity and Control
The Sharp ZHU series also integrates WiFi connectivity, allowing our client to monitor and adjust their heat pump’s settings remotely via smartphone. They can track energy consumption, set temperature preferences, and even receive notifications if the room temperature exceeds their preferred limits. The system also features motion-sensor technology, which optimizes energy use by detecting when someone enters or leaves the room.
For homes like the one in Pierrefonds-Roxboro, where energy efficiency is a priority, this real-time monitoring and control system is a game-changer. It helps homeowners save on electricity costs while maintaining optimal indoor comfort year-round.
Built for Quebec Winters: Reliable Heating at -27°C
One of the most important factors for our client was the system’s ability to provide consistent heating during extreme cold. The Sharp ZHU 12,000 BTU mini split is designed to operate efficiently down to -27°C, ensuring warmth even on the coldest days of the year. Many heat pumps struggle in freezing temperatures, but the Sharp ZHU series is built specifically for cold climates, making it an ideal solution for Quebec homeowners.
Warranty and Long-Term Reliability
At AirGreen, we stand behind the products we install. The Sharp ZHU series comes with a 10-year warranty on parts, labor, and the compressor, giving our clients peace of mind that their investment is protected for years to come. This comprehensive warranty is a testament to the quality and durability of the Sharp system, and it aligns perfectly with AirGreen’s commitment to customer satisfaction.

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.
Model, capacity and price, in writing. We also check whether the model qualifies for assistance programs.
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.
Remote, modes, filters: we show you the essentials before we leave.

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.
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.
