On average, the cost of ducted air conditioning installation for residential properties ranges from $5,000 to $30,000+. While the overall cost will depend on a number of factors, it pays to know the price estimates to create a reliable budget plan.
Ducted air conditioning systems improve the circulation of hot and cool air within a room. They come with a Zone Control function which can be adjusted to suit the heating and cooling needs of each room.
Unlike other air conditioning types such as wall-mounted and split type, ducted systems require a more complex installation process. The use of ducts and other features makes it expensive to buy and install.
How Much Do Ducted Air Conditioning Systems Cost?
Daikin’s inverter ducted systems with 15.5kW (cooling capacity) and 18kW (heating capacity) cost around $5,275, excluding the installation cost.
You may refer to their price list to check the price of ducted air conditioning units or ask your local air conditioner supplier for accurate figures. In choosing the appropriate ducted air con, consider the following aspects:
The size, type, and brand/model
Many specialist companies supply and install air conditioning systems. Comparing quotes from different air conditioning installation companies gives you a better understanding of their scope of work in analysing price differences.
Determine the standard cost of ducted air con units to know what fits your budget and property requirements. You can check other brands such as Mitsubishi, Fujitsu and Panasonic. These are recognised brands with up to 5 years warranty.
There is a variety of other brands with varied costs, warranty and other factors to consider. Ensure your decision is based on the whole of life costs, not just the cheapest.

Heating and cooling capacity
Checking the heating and cooling capacity of ducted systems helps you to determine which type is best suited for your needs. If cooling your home is more beneficial, you can choose the conventional type of ducted air con.
On the other hand, you may invest in ducted reverse cycle air conditioner if both heating and cooling is what your home and your climate requires.
In terms of energy efficiency, check if the products are regulated by Australian Standards including Minimum Energy Performance Standards (MEPS) and Energy Rating Label (ERL).
The energy rating label compares the energy efficiency level of different models with the same size and capacity. You can use this calculator for comparison.
The Star Rating also provides energy performance information of the product, allowing you to choose the most efficient one within your budget. Ask your ducted AC expert about the unit’s energy ratings to help save running costs.

Ducted System Air Conditioning Labour Costs
Many companies that provide air conditioning services charge fixed prices for installation. Tradies may also charge hourly rates depending on the size and difficulty of the job. Their level of experience also factors in the cost.
|Labour Price||Hourly Rate (Guide)|
|New South Wales||$55|
Air conditioning installers from New South Wales offer the lowest hourly rates of the states and the increase in labour cost may mean a low supply of AC technicians in that area.
It helps to know how ducted air con experts charge per hour to organise your budget. You can source information from your neighbours or their past clients to have an overview of the average hourly cost you are expected to pay for ducted AC installation.
What are the Factors that Affect the Cost of Ducted Air Conditioning Installation?
Most air conditioner installers will tell you about the common factors that influence ducted air conditioning prices. One of which is your location. Other aspects may include:
1. Type of unit
Are you looking to install a conventional type of ducted system or ducted reverse cycle air conditioning unit? Standard ducted types cool the home, while reverse cycle systems have dual function.
In terms of product density, the cost of installation for ducted reverse cycle units tend to be higher than the usual types.
2. Ducts and Grilles to use
The number of ducts and grilles that you will use depends on the number of rooms and size of your house. If you require multiple rooms and floors to be cooled or heated, you will need more ducts and grilles installed, thus increasing the installation’s cost.
3. Available space on the roof
The size and layout of your roof also determine the aircon installation costs. If your existing roof design has enough space to fit the ducts, it is easier to access. However, in some cases, modifications are required to adjust the roof trusses, incurring an extra cost.
4. The positioning of the indoor and outdoor unit
The distance between the indoor and outdoor unit affects the unit’s efficiency and ducted air conditioning installation cost. The closer they are, the lower the price of the installation.
Greater distances require additional materials to be used, which adds to the cost.

The Cost of Ducted Air Conditioning Systems Based on Your Property Size
The size of your property determines what type of ducted system to install. You can expect to pay the following ballpark figures depending on your home’s air conditioning needs.
(single storey, two bedrooms)
|$5,000 – $7,000|
(single storey, three bedrooms)
|$8,000 – $13,000|
(two or more storeys, four bedrooms)
|$15,000 – $30,000+|
New homes are less likely to encounter installation issues as they are being planned for during the construction phase. But if you are installing a brand new ducted system in your existing home, consider important details such as:
- Your ceiling height and floor plan
- Materials used in constructing your home
- The level and quality of insulation
- The dimension of each room to be cooled or heated
- The number of people living in your home
- Positioning and size of doors and windows
When choosing what air conditioning size will suit your home’s heating and cooling requirements, consider the total floor area of the daytime living areas (e.g. hallways, stairs, family rooms, kitchens, lounge rooms) and the number of floors that you have.
Remember, the higher the ceiling, the larger power capacity you will need. The more rooms and floors that you have, the more labour and materials it requires. Pay close attention to other factors which will add to the cost including:
- Uninsulated roof/attic spaces
- Frequently used bedrooms at midday (e.g. bedrooms)
- West-facing windows (where the setting sunlight in the heat of the day is directed to your home)
How Much is Ducted Air Conditioning System Maintenance?
Proper maintenance may extend the life and performance of your ducted system and shouldn’t be overlooked. After the installation, it’s best to have the system regularly checked.
Some companies charge an annual maintenance cost of $150, including GST. The package may include cleaning of filters, checking of bearings and motors, and inspection of zone controls. Expect to pay higher amounts for any remedial works or materials.
Newly installed ducted air con units quickly deteriorate without regular cleaning and maintenance. This can attract increased cost if left unmanaged. Hire a local air conditioning installation expert to install and maintain your ducted system the way you want it.
