A Tale of Comfort, Efficiency, and Invisible Engineering
A Customer's Dream, Realized
The Challenge and the Solution: In the quaint yet bustling neighborhood of Dollard-des-Ormeaux, a customer with a vision for their home comfort sought the expertise of AirGreen, a name synonymous with quality HVAC solutions in Montreal, Laval, Longueuil, North Shore, and South Shore. The mission was clear yet challenging: to install a state-of-the-art Sharp ZHU 18,000 BTU wall-mounted heat pump that promised not just to heat and cool their space but to do so with unparalleled efficiency, minimal aesthetic disruption, and advanced technological features.
The Sharp ZHU Advantage: Sharp, a brand revered for its innovation, delivered with the ZHU model – a machine that embodies efficiency with its impressive 25.0 SEER rating, WiFi capabilities, and the cutting-edge SPOT AIR function for precise airflow control. Notably, its adoption of the R-32 refrigerant marks a significant step towards sustainability, reducing greenhouse gas emissions and energy consumption. This model also boasts a formidable cooling and heating capacity, even in temperatures as low as -27°C, making it an ideal contender for the extreme Quebec climate.
Seamless Installation, Uncompromised Aesthetics
Masterful Placement: Our team, equipped with the intricate knowledge of both the product and the customer's needs, embarked on the installation process with a keen eye for detail. The challenge was to integrate this sophisticated system into the customer's home without the need for further renovations or visible conduits that could mar the aesthetics of their carefully curated space. The solution was a meticulous installation strategy that placed both the interior and exterior units in positions where the piping and electrical wiring remained invisible, preserving the integrity of the home’s design.
The Customer's Delight: The result was nothing short of spectacular. Our customer was presented with a seamlessly integrated Sharp ZHU heat pump that not only met but exceeded their expectations in terms of performance, aesthetic harmony, and technological prowess. The SPOT AIR function, in particular, offered a tailored comfort experience by automatically adjusting the airflow to the customer's location within the apartment, whether in the tranquility of their bedroom or the liveliness of the living area.
Beyond Cooling and Heating: A Technological Marvel
Innovative Airflow Design: The ZHU series shines with its inspired use of nature in its design – from the dragonfly wing-shaped indoor fan blades that enhance airflow by 30% to the exterior compressor blades that draw from the golden eagle and albatross for improved efficiency. This biomimicry not only optimizes performance but also serves as a testament to Sharp’s commitment to environmental consciousness.
Plasmacluster Ion Technology: Further distinguishing the Sharp ZHU is its Plasmacluster ion technology, a groundbreaking feature that emulates natural air purification processes. This system actively combats airborne pathogens, allergens, and odors, ensuring the indoor air quality is pristine. It's a feature that not only enhances comfort but also protects the health of our client’s household.
Coanda Airflow Control: The utilization of Coanda effect technology ensures even distribution of air throughout the room, eliminating hot or cold spots and creating a uniformly comfortable environment. This is complemented by the multi-zone capability that allows for simultaneous control of various indoor units, ensuring holistic comfort across different spaces.
Smart Connectivity for Effortless Control
The inclusion of WiFi connectivity brings the ZHU series into the smart home era, allowing for real-time monitoring and control through a smartphone app. This not only offers convenience but also promotes energy efficiency through detailed consumption tracking and the ability to adjust settings based on real-time occupancy data.
Energy Efficiency and Sustainability: A Core Philosophy
The ZHU series, with its Energy Star® certification, represents a leap towards sustainability. The use of R-32 refrigerant and the energy-efficient design reflect our commitment to reducing our carbon footprint while providing our customers with cost-effective heating and cooling solutions.

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.
Good habits, once the unit is in place
Six simple habits that keep the unit going. Your list stays on this device.
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.
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.
