Whether it’s a Ducted unit, an underfloor Gas heating unit, Single Split – Multi Split – VRV; it’s only a part of the overall system. Many other items make the system complete. If you have a Daikin, Brivis, Mitsubishi etc….does not mean all the other components are made or supplied by them.

You have many choices in what you see as a finished product, some are functional, aesthetic, practical, necessary and some are a requirement. You will get a better understanding of what goes into making up a system and the choices available for any type and any budget.


Flexible duct, known as “flex”, comes in a variety sizes and R values. Typically, flexible plastic or metalized Mylar over a metal wire coil to make it round. The insulation is usually glass wool or polyester fibre for thermal insulation (rated from R0.6 – R2.0). The outer skin is a protective layer surrounding the insulation, and is usually composed of polyethylene, metalised PET or plastic. Duct should be manufactured to meet the requirements of the building code of Australia and all relevant Australian standards and statutory requirements. Some manufactures offer duct with fire retardant / rating values and certification.

Flexible insulated duct is commonly used throughout Australia on residential system installation, mainly on reverse cycle and gas heating systems. This is what conveys the air from within your home to the unit and then conveys the heated or cooled air into the home through the registers. The quality, R value, sizing and installation of the ducting has a HUGE impact on the performance of your system.

The Higher the R value rating of the duct, the lower the losses through the duct into the hot roof space (upto 65C) or cold underfloor area. The type of insulation is not an issue or the thickness of; the only measure should be the R value just like home insulation!

Return air grilles (most commonly fitted with a filter), draw air from within the home or conditioned area, passes through a filtering process before entering the unit to be heated or cooled to the desired temperature. You could have multiple returns depending on the system installed or as unit access requirements dictate.

Mainly constructed from lightweight aluminium powder coated white finish, these can be located in a ceiling, door, and wall or in joinery. For floor mounted types, these are made from heavy duty pressed metal sections to withstand traffic.

The most common and popular type is the ceiling “egg-crate” design offering a free area of approximately 90%. They come in many different sizes and should be correctly designed and sized to suit the airflow volume of the system.

Available in any size and colour combination you require.

Any fixture that distributes the heated or cooled air throughout your home is called either a GRILLE, DIFFUSER or REGISTER, however many alternatives are available. We will advise you on whats best for your application.

Many considerations need to be made to select the correct type of diffuser. Various styles, materials, finishes, shapes are available. Some choices are functional, some are decorative; some are chosen for aesthetics and others for price.

Construction is usually plastic, aluminium, metal, stainless, timber and cast iron. Plastic diffusers are generally more common and a better option for cooling (they don’t condensate). Other grilles offer a greater variety and are much better looking.

See from the choices below some examples of what you can select. If its not here, we can custom make it!

The Linear Slot Diffuser is a superior, modern and flexible mode of air distribution.

The Air Grilles Slot Diffuser can be manufactured from 1 to 12 slots wide. Slot widths may be either 20-mm or 25-mm. It is recommended that the slot diffuser, which is manufactured exclusively of aluminium extrusion, should not exceed a one piece length of 2 metres. For continuous slot diffuser assembly, aligning strips are provided for ease of installation.

The provision of bends to specified angles is possible and the ends may be straight cut or mitred as required.

Condensation may form on these diffusers, careful consideration must be given!

Jet Diffusers are designed to provide an attractive option for heating and cooling large areas. These diffusers are perfect for situations where large supply air quantities and throw distances are required, constructed from three cones that provide a uniformity of appearance through the range.

Adjustable air supply nozzles are applied in the supply of cold or warm air in rooms where long throw distances and low noise operation are required. By combining individual nozzles into a block, the throw distance is increased proportionally. There is a choice of several mounting methods.

Supply nozzles VS-5 are adjustable. The air jet can be adjusted:

  • manually, in all directions, within a ±30° range
  • by means of an electric motor, in horizontal and vertical direction, within a ±30°range

There is two common standard sizes –

  • 350 x 150 (large) suitable for air conditiong systems or a dual gas / cooling system
  • 300 x 100 used mainly for for gas ducting heating only due to lower airflow delivery.

We recommend you always install the larger grilles if you plan to install Add-on Cooling in the future and ensure you utilise upgraded duct sizes at the initial installation.

The range of floor grilles is almost endless, many styles, colours, finishes, material construction, plastic, metal (brass), aluminium, cast iron, timber and stainless steel. Here is just a few samples -

A zoning system provides you with the flexibility to cool or heat independent areas. A zone can be a single room, like a lounge room or a designated set of rooms, like children’s bedrooms. You can also condition your entire home. Some zoning system can detect how many zones you are currently operating and automatically adjust its output to match the requirement. This means that if you only want certain parts of your home heated or cooled, you can, while not wasting energy.

Available in a wide range of options; shapes, configurations, materials, finishes and coatings - to meet the requirements of almost any project from a screening perspective. Aerodynamic efficiency reduces air intake and air discharge resistance and therefore saves operating cost.

High resistance to rain ingress for enhanced weather protection. Manufactured from corrosion-resistant materials for durability and maintenance-free operation.

If noise reduction is required, acoustic louvre panels may be used. Plant room ventilation louvre systems can be configured to provide the solution to your specific requirements.

With a plant room ventilation louvre, the possibilities are endless.

Also a louver door system is available, robustly constructed in extruded aluminium box section to provide the strength required to hang a large louvre door.

We only use and recommend metal trunking made from Colorbond on the external walls. Plastic capping will not last the distance and does not come in many colour options to blend in with your enviroment. You can match the colorbond trunking to suit your wall, downpipe or gutter colours.

This covering is used to cover and protect the refrigerant piping, insulation, wiring and drains between the indoor and outdoor units from the elements.

For more information on the colour range available, checkout the Colorbond Brochure

Air conditioning outdoor units and external gas furnances can be placed on precast concret slabs with anti-vibration mounts, or poly feet with anti-vibration mounts. Also, these units can be sat on many different types of brackets such as heavy duty galvanised and slim-line foldable “L” shape in powder coat or stainless steel finish, all with anti-vibration mounts.
