A New Standard in Energy Efficiency and Home Comfort
We recently completed an exciting installation project in Saint-Bruno, located on Montreal’s South Shore. The product at the heart of this project? The Sharp ZHU 12,000 BTU wall-mounted heat pump, a machine engineered for both extreme climates and energy efficiency, perfectly suited for Quebec's rigorous weather conditions.
This installation, part of our ongoing efforts to provide cutting-edge HVAC solutions, showcases the Sharp ZHU's excellent heating capabilities, which remain effective down to -27°C. The client in Saint-Bruno opted for this model for its impressive cooling capacity in the summer and its reliable heating in the coldest months of winter.
Why the Sharp ZHU is the Ideal Choice
We at AirGreen recommend the Sharp ZHU series to many of our customers for several reasons, but this particular installation highlights its unique features. Here’s why this model is a game-changer for homeowners like the one in Saint-Bruno:
- Energy Efficiency: Rated at 25 SEER, this system is not just about comfort but also about reducing electricity bills. With rising energy costs, this unit ensures the homeowner keeps their expenses low while enjoying superior indoor climate control.
- R-32 Refrigerant: The system uses R-32 refrigerant, which significantly reduces its environmental impact. Not only does it have a lower global warming potential than older refrigerants, but it also improves the system’s efficiency by roughly 10%, leading to further energy savings.
- Quiet Operation: With a sound pressure level of only 22 dB(A) inside and 49 dB(A) outside, this machine runs almost silently. This makes it an excellent choice for homeowners who value a peaceful environment, especially during the quiet nights of winter.
- LogisVert Grant: One of the most exciting aspects of this installation is the financial advantage it offers. This Sharp ZHU model is eligible for the LogisVert Grant by Hydro-Québec, awarding the homeowner $2,268, the highest grant available for a 12,000 BTU unit!
A Thoughtful, Efficient Installation Process
The installation process in Saint-Bruno went off without a hitch. We arrived at the home, assessed the best placement for the interior and exterior units, and completed the entire project in a matter of hours. The indoor unit measures 41.42 x 9.80 x 12.44 inches, fitting seamlessly into the living space, while the exterior unit (at 30.72 x 10.59 x 21.25 inches) was discreetly installed, keeping the home's aesthetic intact.
Our technicians also took the time to run all necessary piping, ensuring optimal efficiency. The unit uses 1/4-inch and 3/8-inch piping for refrigerant, and our team made sure to protect these with insulation to maximize the system's performance.
Impressive Heating Capacity in Harsh Winters
One of the key factors in the homeowner’s decision was the Sharp ZHU’s ability to perform at extreme temperatures. Many systems lose efficiency as the temperature drops, but this heat pump continues to provide warmth even in the most extreme cold. Rated for temperatures as low as -27°C, this model ensures that the home will remain cozy and comfortable, no matter how cold it gets outside.
Advanced Features: The Plasmacluster and Coanda Effect
Plasmacluster Air Purification
The Sharp ZHU doesn’t just heat and cool—it purifies. The system is equipped with Plasmacluster technology, which mimics the way air is purified in nature. This technology releases positive and negative ions, which neutralize airborne bacteria, viruses, and allergens, ensuring that the air in the home is not only the right temperature but also clean and healthy.
- Eliminates airborne viruses
- Removes mold and microbes
- Fights odors and tobacco residue
- Reduces allergens
This feature was especially appealing to the homeowner, who wanted a system that not only improved comfort but also contributed to a healthier indoor environment.
Coanda Airflow Control for Perfect Temperature Harmony
Another standout feature of the Sharp ZHU is its Coanda airflow control. This technology directs airflow along the ceiling or walls, preventing uncomfortable drafts. The Coanda effect ensures that air circulates evenly throughout the space, maintaining a consistent temperature in every corner of the room.
The long diffuser flap on the indoor unit allows air to be spread up to 15 meters, making it ideal for large or open spaces like the living room in this Saint-Bruno home. This ensures that the entire room benefits from the system’s performance, without any cold spots or direct air blowing on the occupants.
Connectivity and Smart Technology
In today’s smart homes, connectivity is key, and the Sharp ZHU delivers. Equipped with WiFi, this model can be controlled via a smartphone app, allowing the homeowner to adjust the temperature remotely. This feature is particularly useful in Quebec’s unpredictable climate, where being able to turn on the heat or air conditioning before arriving home makes all the difference.
- Real-time monitoring of temperature and humidity
- Energy usage tracking to help homeowners optimize their consumption
- Remote operation, ensuring the home is always at the perfect temperature

The job tools
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.
How the job unfolds
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 we check on a job like this one
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.
Generic illustration of this type of installation, not a survey of this job site. Tap a number.
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.
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.

The right pages, at the right time
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.
