What is a Ducted Air Conditioning System?

Similarly to split air conditioning systems, ducted systems consist of a heat exchanger cabinet, which is located outside and an internal unit that is usually hidden in the roof cavity or under the floor. The internal unit provides clear filtered air that can then be ducted to any room within the building. Ductwork refers to the network of sealed flexible tubes that connect the internal air conditioning unit to each room vent. This network of tubes also recycles air through a return air panel to remove dust, dirt and airborne particles.

Fully ducted air conditioning systems work on the heat pump principle. Warm air is drawn into the system and cooled by a refrigerant, and then the hot gas byproduct is pumped through a heat exchanger before liquefying and cooling again. Reverse cycle ducted air conditioning systems do this but can also reverse the process, which means they can be used for both cooling and heating.

A central command unit can allow adjustments to be made for the comfort level in each area. This means that different temperatures and comfort zones can be set based on room usage or individual preference. Some of these central units have WiFi and remote control abilities, so you don’t even have to be in the building to make sure that the environment is just as it needs to be.

Why Choose Ducted Air Conditioning?

A ducted air conditioning system provides a quiet, clean and effective way to distribute air around your home or business. It provides a next-level solution to climate control, using an even dispersion of airflow throughout the building so that the climate in each room is optimised. Our customers choose ducted air conditioning for several reasons:


ducted systems are relatively unobtrusive as ducts are hidden in the roof space. The only visible part is the outlet in the ceiling or floor of each room, but even this looks flush and discrete.


ducted air conditioning systems have high energy and efficiency ratings and because only the grilles are visible in each room, they are remarkably quiet.


rooms can be individually zoned or simultaneously set to specific comfort level settings.


ducted systems provide a recirculating feature, which filters and cools air multiple times.


systems have a central temperature and zone control with set and forget timers and can be operated remotely.


by creating zones, you can save on the costs of unnecessary heating and cooling.


ducted systems provide an even amount of air distribution, which means there shouldn’t be any unwanted hot or cold spots in your rooms

How to Choose a Ducted System?

When it comes to choosing any air conditioning system, it’s all about your personal preferences and unique needs. If you are considering an air conditioning ducted system, you might want to ask yourself the following questions:
  • Are you most concerned with upfront or long-term cost? Some other systems might cost less upfront, but they will consume more energy in the long term or their warranty may not be as reliable as other more reputable suppliers. It’s vital to understand the long-term costs, including ducted air conditioning installation and maintenance.
  • How many rooms do you need to control? The number of rooms you need climate control for is a fundamental question. This will impact the cost-efficiency of the systems you are considering.
  • How big are the spaces that you need to control? The system you select will need to be sufficient for the room size. It is expensive to replace a system that is too small, so it’s vital to get this right from the beginning.
  • Does the system meet energy performance standards? Make sure you choose a system from well-known brands such as Daikin, Mitsubishi Electric, Actron, Actron Air, Panasonic, Samsung, Fujitsu  and Temperzone
  • How will it be installed and maintained? You need to have confidence in the company designing the specifications for your air conditioning system to ensure it is optimised and your warranty remains valid. You also need to know where you’ll go if you need ductwork replacement and repairs.

What is the Cost of Ducted Air Conditioning?

Ducted air conditioning is one of the most comprehensive forms of climate control on the market today. That means that unit and installation costs may be higher when compared to alternative systems. After all, there is a central unit and outdoor compressor as well as air ducts, wiring and drainage to account for. However, ducted air conditioning is very much an investment and one that has immediate returns.

The price of every ducted system, as well as running costs, will vary depending on the type and size of system you need, its energy rating and the size of the space to be controlled. However, at Eastern Air Conditioning, we are dedicated to giving upfront and transparent costs for ducted air conditioning systems and their installation, so you’re fully aware of the investment you are making. We work with leading brands such as LG, Lennox, Hitachi, Toshiba, Rinnai, Kelvinator and Braemar evaporative air conditioning, so are perfectly placed to compare costs. We can also help you compare the long-term costs and benefits of a ducted air conditioning system with other systems to make sure it is the right choice for you.

Some feedback from our valued customers

“It is rare to get such perfect customer service in today’s day and age, but I was unbelievable impressed with Eastern Air Conditioning! I contacted them on Friday afternoon for a small domestic job and the staff went out of their way to ensure it was completed before I left for work at 8am on the following Monday. Could not fault the service, quality of work, punctuality and price. I would definitely use them again whenever needed!”

Casey – Cronulla, Sydney

“I have employed the services of Eastern Air Conditioning at our pub since 2018 as our original providers were not meeting our needs. Eastern Air Conditioning have met and gone beyond our expectations, with a great maintenance program, the ability to solve any problem and they will come out at a moment’s notice. Even with the 40+ degree heat waves, they were able to meet our needs. I highly recommend Eastern Air Conditioning above all the many providers I have dealt with over the past 16 years running pubs.”

John – Gregory Hills Hotel, Sydney

“Excellent customer service. Andrew and his team have completed works at our commercial job sites, including the Kings Park Tavern and City Tattersalls Club, Sydney. He is polite, punctual and a great person in general to deal with. I can highly recommend the company based on our first experiences working with them and will be dealing with Andrew and the team in the near future!” 

Brent – Clockwork Constructions, Sydney

What is a Multi Split Air Conditioning System

A multi split air conditioning system is a type of split air conditioner. However, instead of only being able to cool one room at a time, a multi split can provide conditioned air to several rooms. To achieve this, multi-split air conditioning comprises one external unit and several indoor units. The indoor units can be wall-mounted, floor standing or ceiling mounted and are connected by refrigerant pipelines, condensate drain lines and power cables to the single outdoor unit. The outdoor unit comprises a compressor and condenser coil and is housed in a robust cabinet. The compressor supplies the right amount of refrigerant to each coil to deliver the maximum cooling rate for each indoor unit. The refrigerant flow then automatically reduces as the set temperature in each room is achieved and then sustains this level. Each indoor outlet can be individually controlled, but they are all connected to just one powerful outdoor compressor unit.

Portable Systems

Freestanding or portable units work like plug-in heaters and can be easily installed by connecting to a power outlet.

Split Systems

Split systems have two separate parts, one inside the building and the other outside, connected by cables and pipes. Split systems can be wall or floor mounted, or you can have ceiling mounted cassette systems.

Water Cooled Systems

Water cooled package units again contain heating, cooling and compressor technology in one package unit. However, they are mounted in the ceiling and reject heat to a condenser water loop.

Multi Split Systems

Multi split systems work in the same way as split systems but allow you to connect one outside unit to several inside units.

Rooftop Systems

A rooftop package unit combines the simplicity of a split system with the flexibility of ducted air conditioning. The compressor, evaporator and condenser units are combined into one package unit that can be mounted on the roof and connected to the inside of the building via a duct.

Ducted Systems

Ducted air conditioning systems work in a similar way to split systems, but cool air is filtered via a ceiling duct, enabling you to have several outlets connected to the same unit.

VRV and VRF Systems

VRF/VRV systems enable several fan coil units (FCU) to be connected to a single condensing unit using only refrigerant piping and electrical wiring. This makes systems such as Daikin VRV more efficient as they operate based on demand. What’s more, with a wide selection of unit types and sizes available, these systems are incredibly versatile.
