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 Art of Seamless Integration: A Behind-the-Scenes Look at Our Expert Installation
When it comes to enhancing home comfort with minimal aesthetic disruption, our recent project in the scenic area of Île-Bizard–Sainte-Geneviève stands as a prime example of AirGreen's dedication to excellence and client satisfaction. This installation of a Sharp ZU1 Mini Split Heat Pump not only elevated the indoor climate but did so while preserving the integrity of our client’s home decor—a challenge delightfully met by our skilled team.
Unobtrusive Elegance
Nestled neatly above the doorway, the sleek 18,000 BTU Sharp ZU1 unit now serves as a testament to unobtrusive design and powerful functionality. Our team was tasked with a specific and crucial requirement: all pipelines and electrical wiring had to be meticulously hidden behind the unit. The homeowner expressed a strong desire to avoid any post-installation renovations, prompting our team to employ a strategic approach during the installation process.
Technical Precision and Aesthetic Harmony
Achieving such a clean setup required not only technical know-how but also a keen eye for aesthetic detail. The result is a testament to AirGreen’s commitment to quality—both in the performance of the heat pump and its seamless integration into the home’s existing design. The Sharp ZU1 model, renowned for its efficiency and discreet operation, proved to be the perfect choice for this project. The unit operates at a whisper-quiet 25 dB, ensuring that peace within the home remains undisturbed.
Client-Centric Installation
One of the highlights of this installation was the use of the new R-32 freon, which aligns with upcoming government energy efficiency standards set for 2025. This choice not only future-proofs the system but also reinforces our commitment to eco-friendly solutions. The 24.0 SEER rating of the unit further underscores its energy efficiency, translating into long-term savings and reduced environmental impact for our client.
Moreover, the Sharp ZU1 comes equipped with features like Wi-Fi connectivity and Energy Star® certification, making it a pinnacle of modern home climate control technology. Its capacity to provide consistent heating down to -27°C ensures that our client’s comfort is guaranteed, even during the harshest Quebec winters.
Customer Satisfaction: A Seamless Experience
Our client’s feedback post-installation was overwhelmingly positive. They were particularly impressed by the professionalism of our team and the meticulous attention to detail. The absence of visible wires and pipes not only met but exceeded their expectations, contributing to their overall satisfaction with the project.

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.
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.
