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.

Why Choose the Sharp ZU1 for Your Home?
Exceptional Air Purification with Plasmacluster Technology
One of the standout features of the Sharp ZU1 is its Plasmacluster air purification system. This unique technology releases ions into the air, neutralizing viruses, bacteria, mold, and allergens. The result? Cleaner, healthier indoor air for you and your family. Homeowners in DDO with pets or allergies will particularly appreciate this feature, as it ensures a noticeable improvement in air quality.
Enhanced Comfort with Coanda Airflow Control
Traditional HVAC systems often struggle with maintaining uniform temperatures throughout the home. The Sharp ZU1 solves this with its Coanda airflow mechanism, which directs air along walls and ceilings to ensure even distribution. This eliminates cold spots in winter and hot zones in summer, creating a perfectly balanced environment.
Built for Quebec Winters
With Hot Gas Pipe technology, this heat pump can operate efficiently even during Quebec's harshest winters. The system prevents the outdoor unit from freezing and shortens defrost cycles by 60%, ensuring uninterrupted heating when you need it most.
Installation Highlights
The installation process in DDO was smooth and precise, thanks to our experienced AirGreen technicians. Here's how we executed the project:
-
Site Assessment and Preparation: We carefully evaluated the home’s layout to determine the best placement for the indoor and outdoor units. The interior unit was strategically installed in a central location to maximize airflow efficiency.
-
Outdoor Unit Placement: The compact exterior unit was mounted on a sturdy stand, ensuring it remains elevated and protected from snow accumulation during winter.
-
Piping and Connectivity: We used high-quality 1/4" - 3/8" piping to connect the indoor and outdoor units, ensuring efficient refrigerant flow. The system was also seamlessly integrated with the home’s WiFi for remote control.
-
Performance Testing: After installation, we conducted rigorous testing to verify the system’s cooling and heating capabilities, airflow distribution, and energy efficiency.
Customer Benefits and Feedback
The homeowners were thrilled with their new heat pump, praising its quiet operation, energy savings, and ability to maintain consistent temperatures throughout their home. They were particularly impressed with the air purification system, which provided an immediate improvement in indoor air quality.

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.
