Unico is the best air conditioning system on the market. Yes, that’s a bold statement, but mainly because it’s true.
Here’s why:

The Unico System is small, a lot smaller than conventional systems.

And that plays to your advantage in a big way. So, whether you are adding air conditioning to your existing home, building a new custom home, or simply replacing an old system, the Unico System will fit where other systems can’t.
Instead of conventional ductwork, flexible supply tubing is fitted into existing wall cavities, ceilings or floors. Modular air handlers – small enough to fit into cupboards, attics, ceilings, voids or basements—are powerful enough to effectively circulate air throughout your home. Even though its footprint is small, the Unico System delivers the same level of cooling as a conventional system three times its size.

Our supply tubing is designed to be as quiet and efficient as possible, with a nylon inner core and insulation that absorb sound. Our air handlers are designed to isolate noise and vibration, with closed cell, sound-deadening insulation. Together, they bring decibel levels to the equivalent of a soft whisper. While you’ll feel the comfort, you’ll hardly notice it’s running.

Draught Free, Even Temperatures.

Traditional systems distribute air unevenly which can create drafts and uneven temperatures throughout different parts of the room. The Unico System uses a principle called aspiration, creating a gentle suction around itself that draws the room air into its stream of cooled air. This delivers even, draught free cooling, from room to room, floor to floor, and floor to ceiling. The temperature differential is no greater than 2 degrees throughout your home.

Comfortable By Design.

The Unico System removes up to 30% more humidity than conventional air conditioning and heating systems. So, you can keep your thermostat a few degrees higher to achieve the same level of comfort-and that saves on energy costs.

Fits Any Space

Homeowners everywhere are enjoying the high performance and superior comfort of the Unico System. In most cases no matter when the house or building was built or what the physical configuration, installing the Unico System is always a possibility—without compromising the design or architectural integrity.

The Unico System uses less than one-third of the space in the built environment than a traditional system. It can deliver up to 31kw of air conditioning in the same space as a 9kw traditional unit.

The aesthetics of your home are maintained with the Unico System – walls are not taken up by metal radiators that streak or stain. Small, subtle outlets are available in 50mm round or 16mm x 304mm slotted versions to blend perfectly into your design.

Quiet Performance

The air from our system is delivered quietly and seamlessly. The supply tubing is designed to be as efficient as possible and minimize sound which brings decibel levels to the equivalent of a soft whisper. This is due to the nylon inner core and the insulation, which absorb the sound created from the air.

The air handler is also designed to isolate noise and vibration. Each module, including the blower and coil, is insulated with closed cell, sound deadening insulation which ensures that the unit remains quiet. You will feel the comfort that the Unico System provides, without realising the system is running.

Little or No Remodelling

The Unico System fits where other conventional cooling and heating systems can’t – with little or no remodeling required! The modular air handlers and coils can be easily installed into attics, ceilings, crawlspaces, and cupboards.

The flexible small ducts can be routed through existing ceiling, floor or wall cavities – eliminating the need for unsightly and noisy metal ductwork!

Because of all our design features, there is no need to “gut” the home for installation. The process is less disruptive, there’s less mess, less dust, and less installation time. Without the installation requirements of a traditional heating, cooling, and ventilation, the Unico System saves time and money on your construction.

Draught Free, Even Temperatures

Traditional systems “dump” the air which causes draughts and uneven temperatures throughout different parts of the room (as demonstrated in the video above). Through an air principle called aspiration, the Unico System creates a gentle suction around itself that draws the room air into its own stream of air which creates an even, draught-free environment. This has the net effect of lowering the effective room temperature by 2 to 3 degrees. From room to room, floor to floor, and floor to ceiling, the temperature differential is no greater than 2 degrees from where you set the thermostat.

Removes 30% More Humidity

The Unico System provides greater humidity removal, up to 30%, with the superior and efficient design of our cooling coils, creating a perfectly comfortable environment. What this means for you is that you can have your thermostat set higher than you typically would, yet have the conditioned space feel as though your thermostat is set lower, saving you energy and money. (HOW) The illustration to the right shows the amount of moisture left in the space by traditional units compared to the Unico System.

Matches Any Decor

The Unico System offers you a huge selection in outlet choices. Our round or slotted outlets come in a variety of colours and materials, as well as an even more minimalist bespoke design approach in round and custom linear lengths to fit any décor or architecture without compromise.

The Unico System outlets can be installed in ceilings, floors, or sidewalls. In fact, with their less invasive size and complementary colours and woods, you will hardly notice they are in the room. What you will notice is the perfect indoor comfort they provide.


You always hear about air handler efficiency, but did you ever think about ductwork having its own efficiency?

Heat can leak through the walls of the duct (thermal loss) and air can leak through its seams (duct leakage). In both cases, the Unico System is far superior to a conventional system. Insulation and size determine the thermal loss. Workmanship and design determine the duct leakage.

The Unico System ductwork has 1/3 the surface area of conventional ducting so before it is even installed the Unico System ductwork has 1/3 less thermal loss. The supply tubing is also wrapped with insulation and an outer vapor barrier, which keeps nearly all of the thermal energy within the duct.

In the case of duct leakage, the Unico System is engineered for simplicity and air tightness. It has been documented through third-party testing that traditional systems can lose up to 25% of the air that the unit puts out through leaky ductwork. The Unico System loses less than 5%. This means that with the Unico System you’re getting what you pay for.

At the heart of the Unico System is our air handler which contains the blower housing module and fan and coil module.
