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.
Ensuring Maximum Comfort for Oka Homeowners with the Sharp ZHU
At AirGreen, we pride ourselves on delivering the most efficient and reliable HVAC solutions to our customers across the Greater Montreal area. Recently, we completed a notable installation in Oka, where we provided a homeowner with a cutting-edge Sharp ZHU 12,000 BTU wall-mounted heat pump. This project showcases not only our expertise in installing premium HVAC systems but also highlights the superior quality of Sharp’s ZHU series—a product that’s particularly well-suited for Quebec's extreme climate.
This article delves into the details of this installation, explaining the features that make the Sharp ZHU series a leading choice for homeowners seeking energy efficiency, air purification, and reliable heating performance down to -27°C. Let’s walk through the entire process of this installation and what makes it such a standout in the HVAC world.
The Installation Setting: Oka
The installation took place in the beautiful town of Oka, known for its natural beauty and serene landscapes. The homeowner, a frequent traveler, was seeking an energy-efficient solution to maintain a comfortable temperature year-round. With the fluctuating Quebec weather, especially during frigid winters, it was essential that the selected system offered both heating and cooling capabilities. The Sharp ZHU was an obvious choice, providing the right balance of performance, reliability, and cost savings.
Location of installation: Oka
Machine type: Wall-Mounted Heat Pump
Brand: Sharp
Model: ZHU 12,000 BTU
Eligible for Hydro-Québec LogisVert Grant: $2,268, one of the highest available for a unit of this size!
Why the Sharp ZHU 12,000 BTU?
The Sharp ZHU series is among the most innovative and energy-efficient solutions we offer at AirGreen. Not only does this model boast an impressive 25.0 SEER rating, but it also excels in providing consistent heating down to -27°C, making it an ideal choice for harsh Canadian winters. Its versatility extends to cooling as well, offering the homeowner total climate control during Oka’s hot and humid summers.
Additionally, the system’s R-32 refrigerant ensures an environmentally friendly operation, reducing greenhouse gas emissions and making it a greener alternative compared to older refrigerants like R-22. This refrigerant also contributes to lowering the energy consumption by 10%, leading to long-term savings for the homeowner.
Superior Features of the Sharp ZHU Series
Energy Star Certified Cold Climate Performance
One of the most critical features of the Sharp ZHU is its Energy Star Cold Climate® certification, which guarantees that the system will perform even in the most extreme cold temperatures. For a homeowner in Oka, where winters can be particularly severe, this feature offers peace of mind, ensuring that the system will continue to deliver efficient heating even when outdoor temperatures plummet below freezing.
Plasmacluster Air Purification
Beyond energy efficiency and cold-weather performance, the Sharp ZHU stands out for its Plasmacluster air purification technology. This unique feature helps neutralize airborne viruses, mold, allergens, and even stubborn odors, ensuring the indoor air quality remains pristine. This is especially beneficial for households with individuals sensitive to allergens or those looking to eliminate everyday pollutants from their living spaces.
Quiet Operation
Living in a quiet residential area like Oka means homeowners prefer systems that operate as silently as possible. The Sharp ZHU’s indoor unit boasts a noise level as low as 22 dB(A)—quieter than a whisper! Meanwhile, the outdoor unit operates at just 49 dB(A), ensuring that both the homeowner and neighbors are not disturbed, even when the system is running at full capacity.
WiFi-Enabled Smart Features
In today’s world, convenience is key. That’s why the Sharp ZHU’s WiFi connectivity was an attractive feature for this particular customer. Using a smartphone app, the homeowner can monitor the system in real-time, adjust settings, and even control the unit remotely. This smart feature also allows the system to notify the homeowner if there is no movement in the room, optimizing the system’s energy consumption when it’s not in use.
The Installation Process: Seamless and Efficient
At AirGreen, we know that a smooth installation process is just as important as the system itself. Our team of certified HVAC technicians arrived at the homeowner’s residence in Oka equipped with all the necessary tools and components to install the Sharp ZHU 12,000 BTU heat pump. Our top priority was to ensure that the unit was mounted in an optimal location, maximizing both its heating and cooling efficiency while ensuring easy access for future maintenance.
The indoor unit was strategically placed above a door frame, where it could evenly distribute air throughout the room without occupying valuable wall space. Meanwhile, the outdoor unit was installed on a stable, well-ventilated surface to ensure optimal performance during both the summer and winter months.
The installation included:
- Routing the refrigerant lines through a discreet conduit to preserve the aesthetic of the home.
- Testing the system’s operation to ensure that the Plasmacluster technology and Coanda airflow control were functioning as expected.
- Educating the homeowner on how to use the system’s smart features and how to maintain it for long-term efficiency.
Maximizing the Benefits of Hydro-Québec Grants
One of the standout aspects of this installation is the generous grant the homeowner was able to take advantage of. Through the LogisVert program, they received an impressive $2,268 rebate for installing a 12,000 BTU heat pump, the highest amount available for a unit of this size. Additionally, they qualified for a federal grant of $2,500, further reducing the upfront cost and making this energy-efficient system an even more affordable investment.

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.

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.
