Superior HVAC Technology Now Available in Australia

Small-duct, high-velocity (SDHV) central heating and cooling, enjoyed in the United States and Europe for decades, has finally arrived in Australia. The Unico System, the world’s leading manufacturer of this innovative approach to indoor comfort, is making inroads with HVAC distributors, technicians and discerning Aussie homeowners.



As the name indicates, SDHV systems use much smaller ducts, greatly simplifying the installation process for centralised heating and cooling. The small size and flexibility of the supply ducts allows them to weave through wall cavities and floor joists, which would be impossible for a standard-sized system. With this simplified installation, there’s no need to build out big bulky soffits to hide large traditional ductwork.

The air is conditioned by compact, modular air-handling equipment, with cold or hot air achieved with either refrigerant or water coils. Rather than rectangular registers, the conditioned air is delivered through small round (50mm inside diameter) or slotted (178mm x 12.7mm) outlets that come in various colours, metal  or timber finishes. Outlets can be installed in floors, walls or ceilings, and can be painted, stained or wallpapered to blend into the rooms’ decor.

While the innovative nature of The Unico System’s design makes it quick and easy for technicians to install, it also offers several benefits to homeowners, including:

  • Better comfort with draft-free, even temperatures from floor to ceiling
  • Quiet operation — equal to a human whisper
  • More humidity removal in cooling mode, meaning occupants can feel just as comfortable at higher thermostat settings
  • Less than 10 percent thermal transference of conditioned air and virtually 0 percent duct leakage, resulting in energy savings versus conventional systems
  • Better aesthetics, with no need for expensive bulwark and soffit buildouts
