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 Perfect Blend of Comfort and Efficiency
At AirGreen, we pride ourselves on providing top-tier HVAC solutions that cater to the unique needs of our customers. This latest installation in Baie-D'Urfé is no exception. The homeowner sought an efficient heating and cooling solution that would provide comfort all year round, even during Quebec’s extreme winters. The answer? The Sharp ZU1 15,000 BTU Wall-Mounted Heat Pump—a state-of-the-art unit designed to tackle the harshest of climates, ensuring a pleasant indoor environment regardless of the season.
Why the Sharp ZU1? The Story Behind the Installation
The client’s home in Baie-D'Urfé is situated in an area where winter temperatures regularly plunge below freezing. After a thorough consultation, we recommended the Sharp ZU1 for its outstanding heating capacity that performs down to -27°C, making it an ideal solution for Quebec winters. Not only does this unit offer superior heating performance, but it also excels in cooling during the humid summer months, providing a comprehensive solution for all-season comfort.
The Sharp ZU1, with its 15,000 BTU capacity, struck the perfect balance for this mid-sized home. It’s powerful enough to heat and cool efficiently without being oversized for the space, ensuring energy efficiency and long-term savings on utility bills.
But what really made the ZU1 stand out to this customer was its LogisVert Grant eligibility. Thanks to its energy efficiency, the homeowner qualified for a generous $2,172 grant from Hydro-Québec. This is part of a larger federal and provincial initiative to help Quebecers upgrade their homes to more eco-friendly technologies. The fact that the Sharp ZU1 also meets the stringent standards for an Energy Star® certification only added to its appeal.
Installation Day: Precision and Care in Baie-D'Urfé
Our professional team at AirGreen arrived early on a sunny morning, ready to carry out the installation with precision. The first step involved removing the old, inefficient heating system, which had been struggling to keep up with the homeowner’s needs during colder months.
The Sharp ZU1 indoor unit was installed in the living area—strategically placed to ensure optimal air distribution throughout the home. Measuring 41.42 inches in length, 9.80 inches in depth, and 12.44 inches in height, the sleek, modern design of the unit blended perfectly with the home’s interior decor. The homeowner was especially pleased with how quiet the indoor unit operates, boasting a sound pressure level of just 23 dB(A)—whisper quiet, even in operation.
Meanwhile, the exterior unit, with dimensions of 30.72 x 10.59 x 21.25 inches, was securely mounted outside. With a sound level of 49.0 dB(A), it ensures that even when working at full capacity, noise disturbance is kept to an absolute minimum. The outdoor unit is robust and built to withstand Quebec’s harsh winters, thanks to Sharp’s anticorrosive coating and advanced hot gas pipe system that keeps the unit frost-free even in sub-zero temperatures.
Advanced Features That Matter
The Sharp ZU1 isn’t just any ordinary heat pump; it’s packed with the latest in HVAC technology. One feature that sets it apart from other systems is its Plasmacluster® technology, which purifies the air by neutralizing airborne viruses, mold, allergens, and odors. This was a crucial factor for the homeowner, who was concerned about maintaining clean indoor air quality for their family.
- Superior Air Purification: Plasmacluster ions break down airborne contaminants and mold, transforming ions into water molecules that are naturally reintroduced into the environment, keeping your home fresh and healthy.
- Coanda Airflow Control: This technology directs airflow along the walls and ceilings, ensuring a uniform temperature throughout the home without the unpleasant sensation of cold air blowing directly on the inhabitants.
Additionally, the Wi-Fi connectivity feature allows the homeowner to control the system remotely, adjusting settings from their smartphone whether they're at home or away. The energy monitoring function also provides real-time feedback on energy consumption, helping the customer make informed decisions to save on electricity costs.
Built for Efficiency: Environmental Responsibility
At AirGreen, we are committed to offering products that are both high-performing and environmentally friendly. The Sharp ZU1 uses the R-32 refrigerant, which has a much lower global warming potential compared to older refrigerants. This not only makes it a greener choice but also improves the overall energy efficiency of the system by approximately 10%.
Furthermore, the ZU1 is built to handle multi-zone setups, making it perfect for homeowners who may want to add more units in the future. With its inverter technology, the heat pump adjusts its power usage according to the room’s needs, reducing energy consumption and prolonging the life of the unit. This, combined with the unit’s ability to self-clean and defrost efficiently, ensures that the homeowner can enjoy hassle-free operation for years to come.

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.
