Ducted air conditioning is one of the most common types of air conditioning available.  It is found in homes and businesses worldwide due to its many benefits.  In some regions of the world, ducted air conditioning is a luxury.  In some regions, like Brisbane and Queensland in general, it’s almost a necessity for most buildings.

When looking at Brisbane air conditioning, here are some estimated prices for ducted air conditioning:

  • A small home typically involves a price range of $6,000-$12,000 for ducted supply and installation.
  • A standard 2-4 bedroom home may involve a cost of between $8,000-$16,000 for supply and install of ducted air conditioner.
  • A large 4+ bedroom/double-storey may vary from $10,000 – $20,000 for full ducted air conditioning installation.

Given the variety of factors involved and the wide range of pricing options available, it’s best to opt for an experienced specialist who can assist with quotes tailored to your specific needs.  Key considerations include space measurements, budget requirements, and personal preferences.

Consulting a ducted aircon professional will help you get the most out of your ducted air conditioning system without breaking the bank.  However, some background knowledge is helpful when discussing your needs with the experts.

Understanding the costs involved in a new ducted air conditioning system can be confusing.  It can be helpful to think about ducted aircon varying in price due to three main factors; ducted unit pricing, addition of AC zoning, and ducted install costs.  In this article we’ll explore these main 3 costs.

What is Ducted Air Conditioning & How Does it Work?

Firstly, it’s important start with an overview of what a ducted air conditioner is and how it functions.  Essentially, ducted air conditioning is a system based on the refrigeration cycle and designed to provide heating, cooling, ventilation, and conditioning of air in buildings.

Ducted split systems consists of two parts, the outdoor condenser and the indoor evaporator unit.  The condenser (“outdoor”) is typically located in a well-ventilated area outside, and transfers heat from the building to the external environment.  The evaporator unit (“indooSr”) is usually concealed in the roof or ceiling space and distributes cooled air throughout the indoor environment.

The two main units that make up a ducted system are connected by piping and cabling.  Then there are ducts that connect each room or space to the indoor unit.  The ducted aircon system can be controlled with a wall controller or remote control, as well as Wi-Fi controls available on modern systems.  In some cases, an AC zoning system may also be included.

Ducted reverse cycle air conditioning is a type of air conditioner which offers both cooling and heating capabilities in one system.  This reduces the cost of having separate devices for both functions.  With ducted reverse cycle aircon, the indoor environment can be kept at a comfortable temperature no matter what the outdoor climate is.

Commercial ducted systems are often designed to cool the workplace due to benefits of ducted air conditioning for a business, with other heating solutions such as heater banks being used for warming purposes.  However, ducted reverse cycle aircon is becoming increasingly popular in commercial spaces too due to its ability to satisfy both heating and cooling on demand.  This simplifies the heating, ventilation, and air conditioning (HVAC) system in a commercial building and provides maximum comfort for employees and customers alike.

Ducted air conditioners are primarily used for achieving temperature control and humidity regulation.  Air conditioning works by moving air over refrigerant-filled exchanger coils inside an indoor fan unit.  This fan circulates warm or cool air depending on whether it is a heating or cooling cycle respectively.  A condenser fan in the outdoor unit pushes air through this unit to reject heat into the outside environment.

Basic heat pump cycle

Refrigerant moves around the system in order to perform its conversion from high pressure to low pressure.  During its passage through expansion valves, refrigerant switches between vapour (gas) form and liquid form.  This distinguishes it from central air conditioning systems which use water as their local medium for heat transfer instead of direct refrigerant expansion (Dx).

New Ducted Air Conditioning Costs

The initial cost of a ducted air conditioning system is substantial and includes more than just ducted unit price itself.  Along with buying the indoor evaporator unit, outdoor condensing unit, and controller, you must also buy ductwork components such as flexible duct, supply/return air plenums and/or t-pieces.  Transporting these items to your home also carries a fee.

Furthermore, you will need associated components for new ducted AC install like pair coil or pipework, interconnect cables, insulation materials, and mounting equipment.  Electrical materials such as a circuit breaker and safety switch are necessary in most cases.  It’s also possible that you’ll need zoning gear including zoning controllers, modules, and sensors for individual room temperature control.

The cost of labour can be significant when it comes to ducted air conditioners as well.  Installers will typically be joined by technicians, apprentices, and an electrician in part to complete the job correctly.  The hourly pay rate plus superannuation for each team member should be factored into the total cost, along with any staff days off such as holidays or sick leave.

Calculating a ducted air conditioner pricing

Finally, there are business overheads like licenses, insurances, and advertising that contribute to the overall expense.  Clean up materials and rubbish fees can also pop up during an installation or replacement job.  As you can see, there are many costs that aren’t immediately apparent when it comes to a ducted air conditioning installation pricing.

Ducted Air Conditioner Unit

It’s easy to underestimate just how much goes into installing or replacing a ducted air conditioner.  However, if done properly with the help of a reputable installer, it can save you time, money, energy, and sanity in both the short term and long run.

The cost of a ducted aircon unit varies depending on the brand, size, and model that you choose.  It is important to calculate the size based on factors such as building usage, heat load, airflow requirements, and ceiling heights.  Most ducted units come with wired wall controllers or remotes as part of the package, so bear this in mind when considering prices.

Local suppliers may be able to offer competitive pricing due to wholesale buying and lower retail overheads.  Consider asking for any cashback offers or discounts before committing to a purchase.  Furthermore, quality often correlates with price so it may be worth investing in higher-end models from reputable manufacturers such as Daikin, Mitsubishi Electric or Heavy Industries, ActronAir, Panasonic, Toshiba, or Hitachi.

By taking the time to compare prices and research ducted AC models before settling on a purchase, you can save money on your ducted air conditioner system while getting top quality equipment.  You can also safe money in the long term if the best ducted aircon is chosen upfront.

Ducted AC Zoning

Ducted air conditioning zoning is an optional feature that can greatly influence the price when installing a ducted AC system.  From installation to upkeep and maintenance, the price of a zoning system can change dramatically depending on the size, brand, and features you choose.

The number of individual zones will depend on what size of zoning system you decide to go with.  Most controllers offer up to 8 zones as standard, though some extend up to 14 or even 27 zones with smart systems like iZone.  Each additional zone will add both material and labour costs.

When it comes to brands, there are many options available including Daikin and Mitsubishi Electric or third-party options like Polyaire (AirTouch) or All Air (iZone).  Quality may affect price but so do specific features featured in the system.  It’s worth shopping around for the best value for money before making your decision.

Ducted Air Conditioning controls

When looking at features, you should consider how much control you wish to have over each area.  Ducted air conditioning zoning control can range from basic on/off controls to individual room temperature control.  Additionally, there are various added extra functions such as Wi-Fi connectivity, touch screens, motion sensors, timers, and even whole home automation integration which can come included or as an additional cost depending on the model chosen.

Timing is also important.  Having your zoning system installed at the same time as a new ducted aircon system rather than down the line tends to be more cost-effective.  By investing time into researching all elements of ducted air conditioning zoning prior to investing money into purchasing one, you can make sure that in the end you’ll get the most out of this option for a reasonable price.

Ducted System Installation

When it comes to the cost of installing a ducted air conditioner, there are several factors that need to be taken into account.  The size, type and number of units, space available for components, the degree of difficulty during installation, and materials required all have an impact on the final cost.

Larger units are typically more expensive due to being three-phase power units (18kW and above).  They require additional electrical cabling and materials compared to single-phase units (17 kW and below), as well as additional labour for installation.

Due to their electrical nature, ducted air conditioners should not be installed by DIY or unlicensed contractors.  This poses a risk for extensive damage, voiding warranties and insurance claims, or worse – risking lives.  Therefore, it is vital to engage a reputable company with experience managing and performing installations.

The quality of materials and service can vary significantly from company to company.  Low upfront costs may seem tempting but could end up costing far more in the long run due to rogue tradespeople taking advantage of customers.  Unfortunately, these cowboys also often use low quality materials that fail earlier than expected.  A good quality installation will save money in the long run while providing peace of mind that the system is operating as designed with maximum energy efficiency.

Before determining whether ducted air conditioning is suitable for your home, you’ll need to make sure there is enough roof space for the ductwork.  If you’re replacing an existing system, the ductwork should already be in place and can be reused or modified as needed.  A pre-install site inspection can assess quality of existing and suitability to reuse existing ductwork with the new ducted aircon install.

It’s important to consider the locations of both the indoor and outdoor units when installing a ducted system.  Incorrect placement can lead to additional costs due to access issues or extra labour and materials needed.  The indoor unit should ideally be placed in a convenient spot near the return air grille, away from manholes and beams that could complicate future repairs.  It may cost more upfront, but it could save you thousands down the line.

Similarly, when it comes to positioning the outdoor unit, investing in an ideal location will pay off in the long run.  This unit is usually more expensive than the indoor one and acts as the powerhouse of the entire system.  If the condenser runs more efficiently, so does the entire system with potential savings on energy bills.  When placing it outdoors, try and arrange a shady, airy spot if possible and practical.

If you still have questions about the product and how this type of air conditioner works, you can review our section of frequently asked questions about ducted air conditioners.

How do you install ducted air conditioning?

The installation process of ducted air conditioning is a little bit different from the installation of a ductless unit. This type of AC has a compressor and condenser outside, so these need to be connected. The indoor unit is connected to multiple ducts in the ceiling. These ducts end with an outlet in each room while the air conditioning is distributed through the ducts.

The first step in installing ducted air conditioning is measuring the area that needs to be cooled down. The next step is marking out where all the ducts will go, which can be done using a marker pen or chalk on a light surface such as paper or cardboard. The last step in installing this type of AC is connecting all the pipes and then adding insulation for extra protection against heat loss.

Remember that as the Better Homes and Gardens site mentions some advantages of ducted air conditioners are:

  • Cools the whole home through the existing duct systems.
  • Relatively quiet indoor operation.
  • Can be controlled from the home thermostat.

How much to install ducted air conditioning?

There are several points to consider in the cost of installing a ducted air conditioner. Some of these you should consider before choosing a ducted air conditioner if you are still in that process. One of the most important is the size of your house. This is because the cost depends largely on the size and number of rooms you want to warm or cool down.

To do the measurement you have to consider the size of your home, the size and location of the windows, the height of your ceilings, and even the direction your house is facing.

Other questions to answer to have a real quote for the installation are:

  • Where are the windows in each room located?
  • Are you able to use natural breezes at all?
  • Are there areas in your home or business that are cool enough?
  • It is just bedrooms that may need a more advanced cooling and heating system?
  • How are people in the building able to get warm when they need to?
  • Can you use any of what you already have in place?

Air flows and other factors to consider

Due to air flows, you may only need to install your ducted air conditioner in certain areas of your home. Air flows are very important for the operation and expense that a ducted air conditioner unit will represent. An example of this is the article on the myth that keeping the doors closed decreases the energy consumption of a central AC.

As their article mentions this is false and if you have a typically installed air conditioner unit with a central air return, shutting doors is one of the worst things you can do,” Precision says. “It’s right up there with closing vents and beating your outside unit with a sledgehammer.

Don’t forget that for a Ducted Air Conditioning System, maintenance and cleaning are a must. You have to clean all the dust and other particles that may disrupt the passage. You don’t need to do this on your own. At any moment you can speak with the Ice Blast team and have an expert, reliable workforce that is close to you.

Preparation by the homeowner to install ducted air conditioning

  1. When installing ducted air conditioning you must protect your furniture, appliances and valuable objects with a dust cover. Our experts use canvas drop cloth before starting any action. However, there will be drywall dust or sawdust from ceilings that could fall onto surfaces, chairs, and tables.
  2. It would help if you chose where the condenser of your air conditioner will be located. Ducted air conditioners may have a traditional condenser located outside your home that releases hot air or is cooled by water, so they must have a connection to the drain.
  3. You need to decide the location of the controller of the AC. These are normally located in the family room or somewhere else where your family spends more time. Our expert team may recommend a specific place in your house based on the ability to run the wires through the walls.

There are many different forms of air conditioning, with ducted air conditioning being one of the most common.  Commercial ducted systems are commonplace due to the many benefits of ducted aircon for a business.  They are also increasingly popular as home air conditioners due to their discreet look and array of control features.

There are 6 Key Factors that impact the cost of ducted aircon.  In Part One of this topic, we discussed the 3 main points impacting the upfront cost of ducted air conditioning:

  1. The addition of zoned AC control.
  2. The air conditioner installation cost.
  3. The ducted air conditioner price.

Here in Part Two-A, we will discuss one of the main ongoing costs of ducted air conditioning:

  1. The cost to run the air conditioner.
  2. The aircon servicing and maintenance.
  3. The price of air conditioning repairs.

Considering the size of the investment, it is recommended to consider the ongoing cost of ducted aircon before going ahead with any ducted installation.  The cost to run a ducted air conditioner is one of the main ongoing costs.

Interestingly aircon energy efficiency is the number one deciding factor when choosing an air conditioner.  However, the truth is, the cost of running ducted air conditioning varies dramatically depending on many factors such as size, quality, features, and usage.  Your energy provider and tariff will also impact costs involved.

Electric bill charges paper form

These factors have an impact and can even extend standard air conditioner running costs outside of expected ranges.  An ducted air conditioning specialist should be happy to chat about all the specific costs involved and help you along the way.  We will also provide some key points to review here to understand the cost variation and help save wherever possible.

Cost per hour

One of the most common questions when it comes to using ducted aircon is how much does it cost to run?  Specifically, how much does it cost to run ducted air conditioning per hour, per day, per week, per month, per quarter, or per year?

Cooling or heating an indoor space depends on many different factors.  Average costs are:

  • Cool down a room: Between 25 cents to 80 cents per hour. 
  • Warm up a room: Between 13 cents to 36 cents per hour.

On average, this works out to be:

  • ~50 cents per hour to cool down a room.
  • ~25 cents per hour to warm up a room.
  • ~$20 (heating 20hrs/week) – $80 (cooling 40hrs/week) per month per room.

Therefore, for an average 3/4-bedroom home, ducted air conditioning generally costs between $1.00-$3.20 per hour to run in cooling and $0.52-$1.44 on heating.  However, as mentioned, there are many factors at play, which we will explore further.


Sizing of a ducted air conditioner impacts running cost in more ways than one.  This includes the way that it runs and the amount of power it consumes.

kW Rating

When people talk about sizing of air conditioners, this typically refers to kilowatt (kW) rating.  kW is a measure of power that indicates the capacity of an aircon unit.  AC energy efficiency and therefore running costs are largely dependent on capacity.

Ducted AC cooling efficiency is measured using Energy-Efficiency Ratio (EER).  In heating, Coefficient of Performance (COP) is used.  Wall splits have this summarised via a star rating, but unfortunately ducted units do not.

The higher the EER value, the more energy efficient an aircon is.  EER is a ratio of the output (capacity) divided by the power input.  Therefore, as size increases (i.e. output, capacity, or kW rating), energy efficiency automatically decreases.  This means larger AC units will automatically be more costly to run.

Reverse cycle ducted air conditioners have two kW ratings; one for cooling (main figure) and one for heating.  Heating is more energy efficiency, and therefore heating capacity of an air conditioner is usually greater.  This is why an air conditioner costs significantly less to run in heating.

If you access the technical data sheet for your air conditioner, you may be able to work out specific costs involved in running your air conditioner via the SA Government’s appliance running cost calculator.  You can always contact your ducted installer for assistance with such technical information.

Correct sizing

Taking a step back, there are many factors impacting what size aircon you need initially.  However, unfortunately, the correct ducted AC system is not always installed.  This can cause excessive running costs.

If a ducted air conditioner is oversized, it will consume more energy while running, be less efficient, and cost you more in power.  If a ducted aircon is too small, it will have to continually run, work harder, and wear out faster which will cost you more running and replacements costs.

Ducted air conditioning in ceiling

However, there are situations where ducted air conditioner size may be limited.  Common scenarios include physical space in the ceiling and/or single-phase power only available.  A smaller ducted aircon can be used IF set up correctly.  Suitable sets ups include a day/night zoning system or smart zoning option like iZone.

These set ups can save significant money in terms of running cost.  A day/night system means a half-sized ducted AC can be installed and run.  AS discussed, smaller kW rating (assuming suitable for the area served), will automatically be more energy efficient and cost less to run.


There are many different air conditioning brands to choose from.  They vary in terms of quality, features, technology, and price.  At the end of the day, most of us what value for money;  The highest quality product at the lowest possible price.


Popular ducted AC brands include Daikin, Mitsubishi Electric (ME), Mitsubishi Heavy Industries (MHI), Panasonic, Hitachi, Temperzone, ActronAir, Toshiba, LG, Fujitsu, Samsung, and Carrier, just to name a few.  These name-brands vary dramatically in terms of quality and price, but many represent good value for money upfront.

Technology advancements and additions make higher quality/more energy efficient ducted aircons more expensive to produce.  Examples include larger heat transfer coils, more efficient motors, energy saving modes, and new technologies to result in more efficient operations.

However, price doesn’t always correlate with efficiency.  Sometimes the cost reflects clever marketing and media hype.  It pays to visit reputable sites such as Canstar Blue and Choice to conduct your own research, as well as speaking to reputable AC companies.

On the flipside, some brands and models don’t even advertise all their features.  For example, when looking at Daikin wall split systems, the indoor coil size step up from a Daikin Cora to an Alira isn’t promoted, but increases energy efficiency and reduces running costs.

In the ducted range, Daikin splits their ducted units into Premium inverter and Standard inverter models.  The Premium models have a range of internal features that improves efficiency of the units.  Furthermore, Premium inverters have a greater ability (about 10%) to ramp up or down in response heating/cooling demands.  This makes them about 10% more energy efficient, saving on running costs and electricity usage.


Some of the cheaper AC brands on the market save you money upfront but then cost you far more over the year due to the cost of replacement parts and repairs.  For example, Samsung ducted units are relatively cheap to purchase, but their replacement parts are relatively expensive compared to other brands.

In comparison, Daikin ducted units might cost a little more upfront than other brands, but their replacement parts tend to be far cheaper compared to their competitors.  This is especially true if you look up Daikin Dealer near me online.

Some brand may be popular through clever marketing and successful advertising, but then start to have poor part availability after about 7 years.  One example is Fujitsu who use familiar faces to promote their brand, but fall short in the customer service and part availability department during the life of a ducted AC system.


There are many features available with modern-day air conditioners, and many of these are designed to save you time, money, or both.

AC Unit

Some air conditioner features are nice to have, such as a coloured touchscreens and quiet mode.  Some are designed to decrease running costs, such as sleep mode, eco mode, timers, and motion sensors.  Meanwhile, some features can be both when used correctly, such as precision control (0.5 degree adjustments rather than 1 degree) and Wi-Fi connectivity.

Wi-Fi control of a ducted air conditioner allows the system to be turned off remotely, usually via a smart phone app.  This could be when you are away from home and have forgotten to turn the AC off, or laying in bed and want to warm it up before stepping out from under the doona.

Furthermore, Wi-Fi control can be used to switch on the ducted aircon before anyone gets there.  This allows you to start the heating or cooling process early, rather than overloading the system and causing excessive power draw as soon as you get home.  If there is already a large heat load in the room from the hot summer sun, it will take longer to bring the temperature down to desired levels and cost more for you to do so.


Another major feature that can be paired with ducted air conditioning, affecting running costs, is zoning.  A ducted zoning system has a significant impact on overall AC system efficiency.  Firstly, it pays to understand zoned air conditioning and the many options available.

Zoning allows greater control over the heating or cooling demand from an air conditioner by managing each room or zone independently.  Furthermore, you can include a bypass in the zoning system, which means that air recirculates to the indoor unit to control pressure, rather than having to spill out into a constantly open zone in the house.

Another feature that improves efficiency of a ducted system and reduces running costs is the presence of individual room sensors.  These allow more accurate temperature sensing and control, which results in more tightly controlled temperature adjustments.  This not only creates a more comfortable indoor environment, but also reduces demand on the ducted aircon, power consumption, and subsequent running costs.


Ducted air conditioning can be used in many different ways in a variety of settings and environments.  The way in which the ducted system is used makes a significant difference to the running costs associated with the ducted air conditioner.

Heat load

Air conditioning can be a significant contributor to household and business energy expenses.  In Australia, heating and cooling can contribute up to 40% of the average energy usage.

However, are many other appliances that also contribute to a large degree.  For example, in a home this includes:

  • Cooking devices (ovens, cooktops, grilles, etc.),
  • Cleaning devices (dishwashers, washing machines, vacuum cleaners, etc.),
  • Drying devices (clothes dryer, hair dryers, etc.), and,
  • Lighting (florescent, spotlights, feature lighting, etc.)

These other devices also increase the heat load of the indoor space in which they are used.  This increases demand on the ducted air conditioner and subsequent cost of running the AC.  Therefore, it is recommended to run such devices outside of peak ambient temperature times (e.g. avoiding middle of the day in Summer).

Other factors that impact heat load and ducted air con running costs include window treatments, insulation, shading, building orientation, opening/closing of doors, equipment in use, and number of people inside, just to name a few.  A ducted air conditioning specialist can assess all of these factors and help you work out the estimated running costs for your home or business.


One of the key ways to manage heat or cool load is to turn on or set a timer for the ducted aircon to come on early in the morning before a hot and humid day begins.  Similarly, when you have a cold night ahead, start gentle heating early on to keep the chill off in the most cost-effective way.

Furthermore, many of the ducted aircon features outlined previously play a part in how a ducted system is used and running costs are managed.  Many of the features are outlined by the ducted installer and it pays to understand the full functionality of the system upfront in order to save on costs over the life of the system.  You can also access ducted unit brochures and zoning system information online, if not provided on installation.

One of the main settings that affects the cost of running ducted air conditioning is temperature.  Just 1 degree difference in cooling can make a 10% difference to your air conditioner electricity usage!  This adds up to a significant difference in running cost at the end of the day, and end of the quarter via your power bill.

Hand turning thermostat

In Brisbane and South-East Queensland, the following is recommended:

  • Cooling/Summer:       Set temperature to 24-25 degrees.
  • Heating/Winter: Set temperature to 17-18 degrees.

A small adjustment in temperature makes very little difference to the perceived indoor temperature.  However, it can make a massive difference to the cost of running a ducted air conditioner.  Therefore, it is recommended to make minor setting adjustments over time, to achieve significant saving without noticeable impact to indoor comfort levels.

There are many factors that impact the running cost of a ducted air conditioning system.  Ducted aircon can be a cost-effective heating and cooling solution for a home or business, but only if installed and used correctly.  If you need any help reducing the cost of running your ducted aircon, please don’t hesitate to contact us.

Ducted air conditioning is one of the most common types of air conditioning.  It is found in homes and businesses throughout the world due to the many benefits of air conditioning.  Like any heating or cooling system, there are an array of costs involved in installing and maintaining such a system.

The true cost of ducted air conditioning varies significantly based on 6 Key Factors.  These 6 key factors can be divided into 2 main categories: Upfront Costs and Ongoing Costs.

Part One – Upfront Costs:

  1. The ducted air conditioner price.
  2. The addition of zoned AC control.
  3. The air conditioner installation cost.

Firstly, we need to know what ducted air conditioning is and how it works.  We can then move onto understanding upfront costs of a ducted air conditioner.  This is Part One of ducted air conditioning costs, which is the topic of this article.

For ducted air conditioning Brisbane, estimate of supply and install pricing is as follows:

  • Small home or studio:                                     $5,000 – $10,000 + GST
  • Standard 2-3 bedroom home:                                 $6,000 – $12,000 + GST
  • Standard 4 bedroom / small double-storey: $7,000 – $15,000 + GST
  • Standard 5+ bedroom / double-storey home: $8,000 – $18,000 + GST

Considering the number of factors involved and broad price-range, it is recommended to get a free ducted air conditioning quote based on your specific property, personal preferences, and price range/budget.  A ducted air conditioning specialist can save you a lot of time, money, and pain every step of the way.

Part Two – Ongoing Costs:

  1. The cost to run the air conditioner.
  2. The aircon servicing and maintenance.
  3. The price of air conditioning repairs.

It is strongly recommended to consider the cost to run the air conditioner, as well as maintain it, when making such a significant investment.  For this reason, we will go through ongoing costs of a ducted air conditioning system in Part Two of this topic in a separate article. Stay tuned!

Ducted Air Conditioning

There are many frequently asked questions in relation to ducted air conditioning.  This is understandable given the complex nature of a ducted aircon.  There are many moving parts, located inside and outside a building, with connections between both units and rooms being air conditioned.

What is Ducted Air Conditioning?

Ducted air conditioning refers to a refrigeration system use in conjunction with ductwork to condition the air inside a building.  Furthermore, ducted aircon typically refers to a split ducted air conditioner.

A split ducted air conditioner consists of two units; the outdoor condenser unit and indoor evaporator unit.  The AC condenser (“outdoor”) is designed to sit in a well-ventilated location, usually outdoors, and transfers heat with the external environment.  The AC evaporator unit (“indoor”) is typically concealed in the ceiling or roof space and distributes conditioned air to the indoor environment.

The two units are connected by refrigeration pipework and interconnect cabling.  Indoor rooms or spaces are connected to the indoor unit via ducts.  Supply air outlets in each room allow air to flow out of the ducted system and into the room.

The whole ducted aircon system is controlled by a wall controller or sometimes a remote control.  Wi-Fi control is a common extra available with most modern-day ducted air conditioners.  Furthermore, adding an AC zoning system is highly recommended and becoming commonplace.

How does Ducted Air Conditioning Work?

Ducted air conditioning can be a complete system of heating, ventilation, and air conditioning (HVAC), making it a popular HVAC system.  Air conditioning can be further broken down into temperature and humidity control.

The heating or cooling effect is felt as a result of air moving over refrigerant-filled heat exchanger coils.  An evaporator fan is located within the indoor unit to blow air over the coil and out into the room.  There will also be condenser fan/s in the outdoor unit to blow air through the unit and reject heat into the outside air.

With a ducted air conditioner, heat is transferred directly with the refrigerant within the system, making it a direct expansion (Dx) system.  It is worth noting that ducted Dx air conditioning, referred to in this article, is different to central air conditioning which involves heat transfer via a secondary medium such as water.

Refrigerant in the ducted system undergoes conversion from vapour (gas) form to liquid form as it moves around the refrigerant cycle, converting from high pressure to low pressure as it passes through the expansion valve.  The path the refrigerant takes depends on whether a reverse cycle aircon is heating or cooling.

Reverse cycle refers to the ability of an air conditioner to heat and cool using the same device, although not at the exact same time.  Ducted reverse cycle air conditioning is most common form of ducted aircon used as a home air conditioner.

Ducted reverse cycle comes standard for all air conditioner brands as the price between cool only and reverse cycle is minimal.  The advantages of ducted reverse cycle air conditioning out-way the relatively small price difference.

Commercial air conditioning may only be required to cool the indoor environment, with heater banks, heater elements, and other heating equipment in place to warm the workplace.  However, there is a trend towards reverse cycle ducted in the workplace as it simplifies the HVAC system; heating, ventilation, and air conditioning can all be performed by the one device.

Upfront Costs

The upfront cost of ducted air conditioning includes, but is not limited to:

  • Ducted air conditioner units themselves, including indoor evaporator/s, outdoor condensing unit/s, and controller/s,
  • Freight of the ducted units to the installer and then transport to site,
  • Ductwork components including flexible duct, supply/return air plenums, t-pieces, joiners, return air grille/filter/s, supply air outlets, etc.,
  • Freight of the ductwork components to the installer and/or transport to site,
  • Ducted connection materials, including pair coil/pipework, interconnect cables, duct tape, insulation materials, etc.,
  • Mounting equipment and materials, including lifters, supports, brackets, straps, slabs, etc.,
  • Ducted AC drain materials, including drip tray, safety tray, main drain, drain run, p-trap (where applicable), insulating materials, etc.,

  • Business overheads, including licences, insurances, vehicles, tools, phones, upkeep on all equipment, office outgoings and rent/mortgage, training, downtime, administration expenses, advertising, etc.,
  • Clean up materials/equipment, including wet/dry vacuum cleaner, cleaning sprays, wipes, rags, bags, etc., and,
  • Rubbish disposal or collection fees, especially when a ducted aircon is changed over and the ductwork is also replaced.

Industrial workers

As you can see, there is a lot more to a ducted air conditioner price than first meets the eye.  Any new ducted installation or ducted aircon replacement is a relatively large-scale job, like a mini-project, assuming it is thoroughly planned out and executed to the correct standard.

With all this in mind, it pays to use the services of a reputable, experienced ducted installer.  Otherwise, there are many common air conditioning mistakes that can be made that can cost you a great deal of time, money, energy, and sanity in the short term and long run.

Ducted Air Conditioner Price

The first expense to consider is the ducted aircon unit cost itself.  That is, the indoor and outdoor units that make up the system.  Most ducted units also come with a wired wall controller or remote as part of the kit.

Pricing also depends on where you buy the complete AC system from.  Sometimes air conditioning retailers offer discounts or specials.  Some air conditioning manufacturers offer cashback offers at certain times throughout the year, especially winter.

An air conditioning company will typically be able to offer better pricing than in stores.  This is due to wholesale pricing, buying in bulk, lower retail overheads (by using existing warehouse and staff), and often smaller mark ups on AC units.

For the cheapest air conditioner buy price, it is recommended to contact a local AC company directly.  They may have the price of ducted air conditioner units listed online, or they may be able to advise special pricing over the phone or via email.


The first thing that will impact the cost of ducted air conditioning is the size of the system.  This predominantly relates to the KW rating of the system.  The smaller the system, the cheaper the ducted aircon becomes.  However, it’s a fine balance, as an undersized system can end up cost you a lot more in the long run due to excessive run time, overworked units, shortened lifespan, etc.

There is more than just floor square meterage to consider with ducted aircon sizing.  Other factors such as building usage (residential or commercial AC application), heat load, airflow requirements, ceiling heights, building orientation, insulation materials, size/number/treatment of windows, future renovation or fit out plans, etc.

Architecture Composition

The size and number of return air (RA) grille/s and filter/s will also play a small part in the ducted aircon cost.  RA grilles and filters literally filter the circulating air before it returns to the indoor unit.  Some larger ducted units and buildings require a larger and/or more than the one standard grille and filter to allow sufficient air to circulate.


There are many well-known brands in the ducted air conditioner market; Daikin, Mitsubishi (Electric or Heavy Industries), ActronAir, Panasonic, Toshiba, Hitachi, Fujitsu, Fisher and Paykel (Haier), LG, and Samsung, just to name a few.  There are many other brands of ducted aircon available, of varied quality and price.

The quality of the ducted AC unit makes a big difference to the overall cost of the ducted air conditioning system.  Like just about any piece of equipment, there is a wide range of brands available with a wide range of quality to match.

The cost of the air conditioner generally correlates with quality, as you would expect; the better the quality, the greater the cost.  This is because higher quality ducted air conditioner units are the result of superior parts, careful assembly, being built to last, more research and development, greater quality controls, and greater after-sales support.


Within each AC brand, there can be a range of models to consider to further increase choice when it comes to the matter of ducted aircon cost.  The Daikin ducted air conditioner range is a primary example of this diversity.  For example, when considering Daikin units, you may need to decide between the standard inverter and Daikin premium inverter ducted air conditioners.

Ducted outdoor units come with a wide range of differences, contributing to their overall quality, performance, and cost.  This includes vertical or horizontal discharge, single, dual or quad fans, and single or three phase power.

Daikin Air Conditioner

Indoor units vary to some extent also, including slimline, bulkhead, or standard height, low, medium, or high static pressure, and splitting or non-splitting versions.  Sometime the indoor unit requirement dictates what outdoor unit will be required.  For example, limited ceiling space may limit choices for that given space, and therefore system options in general.


As mentioned, the cost of ducted air conditioning generally correlates with quality, synonymous with a brand.  However, buyer beware.  Before you buy anything, it’s important to speak to reputable ducted air conditioning specialist who has accounts set up with a wide range of air conditioner manufacturers.

This way, the ducted aircon supplier can offer you a range of brands, of different qualities, at an accurately reflective price.  As an example, one small installer may only have accounts with Fujitsu and Carrier, making other brands that may be more suitable, such as Daikin and Haier, more expensive options in comparison for that particular installer.

By finding a comprehensive ducted air conditioning provider, you can choose from a diverse range of ducted air conditioners at the best price possible.  Pricing should be consistent with quality and features, to ensure you only pay more for a ducted aircon if it is warranted.

Ducted Air Conditioning Zoning

AC zoning is an optional extra that impacts the cost of your completed ducted system in many ways.  From upfront pricing, to installation, to operational costs, to ongoing maintenance and repairs, zoned air conditioning can vary the costs involved with ducted aircon dramatically.

First is pays to understand what AC zoning is and what are the best zoning options available.  Ducted zoning involves dividing up any indoor area on paper, whether it be residential, commercial, or industrial.  More specifically, the areas where individual control is desired.


Similar to the ducted unit itself, the size of the ducted zoning system will impact the price.  Specifically, the number of individual zones chosen.  Most zoning controllers allow up to 8 zones as standard.  However, this can be extended to 14 and even more (up to 27 zones created in one case) with smart zoning systems such as iZone.

There are many components that make up a zoning system.  For each zone, you require:

  • Zone motor/actuator,
  • Zone barrel,
  • Cable/s,
  • Connections,
  • Sensor/s (room and/or in duct, if elected),
  • Sensor cables (if elected),
  • Installation of all parts, and,
  • Programming/set up of all parts.

Therefore, for each additional zone, there is additional material and labour costs involved.


Similar to ducted AC brands, there is a wide range of brand/manufacturer options when it comes to ducted air conditioning zoning.  Some zoning systems are brand-specific, like Daikin and Mitsubishi Electric, while some come from a third party, like Polyaire (AirTouch) or All Air (iZone).

Price is reflective of quality in most cases, although specific features also play a large part in the cost of a zoning system.  It’s worth asking your installer if they have a preferred zoning supplier, or take the time to shop around and secure a number of cost-competitive zoning options for you to consider.  At the end of the day, you want value for money and the optimum combination of factors for you.

Optimum Air Conditioning Price

It is worth taking some time to review the different types of air conditioning zoning available.  Zoning doesn’t come standard with ducted air conditioner units, and it can make a significant impact to ducted aircon costs, AC system functionality, and overall satisfaction with your heating and cooling system.


Like AC brands, every zoning system has its own list of functions and features.  The primary difference between them starts with the degree of control possible for each area.  Zone control starts with basic on/off, works up to control of airflow percentage, then individual temperature control with room sensors, and you can even have individual room controllers.

Then there are a range of features available for the whole zoning system.  This includes Wi-Fi, touch screens, electronic bypass, motion sensors, timers, child lock, smart home control, and integration with complete home automation.

Some of these features come standard with certain ducted zoning system, while some can be added as an extra.  However, they do add to the cost of the zoning system and therefore complete ducted air conditioning system.

It is worth reviewing each feature and consider how it could be used in your home or business.  While some of them are nice to have (e.g. touch screens), some can actually save you money if used correctly (e.g. electronic bypass).

Wi-Fi or Timers are handy features to have to pre-cool your home before the hot summer sun heats it up while you are away from home.  Meanwhile, Sleep Timer or Mode can improve sleep and save you money also.  It can really pay to chat to an air conditioning company nearby about the different options and your particular requirements.


The timing of your zoning system installation affects the cost of your ducted aircon system as a whole.  Zoning tends to cost less when installed at the same time as a new ducted aircon system, compared to separate installation down the track.  This is because men are already in the roof, running ductwork, and can more easily install each zoning component.

A later installation date of the zoning may also limit your options.  Current zoning systems are not all compatible with older models of air conditioner unit.  Alternatively, additional costs may apply for special adaptors or components to make the zoning gear compatible.

While not impossible, if you are considering zoning, it is recommended to do it when the ducted air conditioning system is being installed.  While it is an additional cost upfront, it can save you considerable money and prevent option restriction down the track.

It is also worth noting that having zoning, or any ducted air conditioning components for that matter, installed in the cooler months of the year will typically save you money.  Many AC companies offer off-peak/winter discounts when suppliers have sales, better unit availability, and it is is safer for staff to work in roof spaces.

Air Conditioner Installation Cost

When is comes to ducted air conditioner installation costs, it’s important to note that installation typically includes everything except the actual ducted air conditioner units themselves.  That includes labour, materials, and equipment required for the installation and connection of a ducted aircon.


Installing an air conditioner depends on many different factors such as the type and number of units, space available for all components, the degree of difficulty of the installation, and materials required.

The size of the ducted aircon has many implications for installation cost.  Larger units are physically more difficult to handle and put in place, thus require more labour and/or additional lifting equipment to install.

Larger units are also more expensive due to being mostly three-phase power units (~18kW and above).  Aside from the considerable step up in pricing from single-phase units (~17kW and below), electrical cabling and materials required with three-phase units is more costly.  A three-phase ducted unit installation can also be more labour-intensive to install.  These differences between single and three-phase power impact the cost of ducted air conditioning.


When looking at getting ducted air conditioning installed, there are usually many companies to consider.  It can be difficult to know where to start and evaluate what costs are reasonable.

Firstly, please do not be tempted to DIY or use an unlicenced contractor when it comes to ducted aircon installation.  Ducted aircon is one area where licensing and certification is really worth it, for warranty, insurance, and legal reasons.

Claim Form

By installing a ducted air conditioner incorrectly and/or illegally, you can cause extensive damage to your home, the electrical grid, the air conditioning itself, and worst case yourself and those around you.  Warranty would also be void, related insurance claims can be declined, and you risk losing a life.  It surely isn’t worth the cost savings upfront, given the costs you are risking down the track.

A good ducted install company will look after you and provide good value for money.  They typically negotiate best pricing possible from suppliers in order to help keep costs down.

The best AC companies also calculate and manage their overheads to further ensure the provision of high-quality ducted installs at the best possible price.  At the end of the day, value for money should be more important than bottom-line pricing upfront.  This philosophy can help you save far more in the long run.


The quality of a ducted air conditioner installation can vary significantly, to say the least.  Pricing from different companies and cowboys can vary dramatically because of this.  As mentioned, price is often an indication of quality.  This is with some exceptions, as there are too many companies out there taking advantage of customers and overcharging for their services.

On the flip side, it is important to note that the cheapest installer may not always be the best.  If they don’t have the experience, knowledge, longevity, and ethics of a reputable ducted installer, you can end up with a nasty, frustrating, and expensive experience, upfront and ongoing.

The materials available for use with a ducted aircon install also vary in quality and price.  A good ducted installer will use higher quality, suitable materials.  This helps prevent air, water, and gas leaks as well as premature material degradation, while improving energy efficiency and allowing the system to operate as designed.

A good quality installation typically saves you far more than the cost difference between a cheap and nasty vs reputable and professional air conditioning installer.  This includes not only money, but also peace of mind and AC lifespan.  There are many mistakes made when installing air conditioning, and many of them come down to the quality of the service and materials provided.


Before considering ducted conditioning, you will need to ensure there is suitable roof space to house the ductwork.  If you are replacing an existing ducted aircon, then this shouldn’t be an issue as ductwork is already in place and can be reused or replaced.

One of the next things to consider when installing ducted air conditioning is the location of both the indoor and outdoor units.  One of the many common air conditioning installation mistakes is incorrect unit locations.  This can be due to access issues but also additional costs involved with installing the units correctly, whether it be due to additional labour and/or materials required.

For the indoor unit, it is cheaper to install it in the most convenient location for the installers.  This may be not far in from the return air grille where the unit entered the roof, along way away from the manhole, hard up against the roof, and/or close to a structural beam preventing ease of future access to the internals of the unit.  It is worth paying a few hundred dollars more now to save potentially thousands in ceiling repairs down the track if cutting the ceiling becomes the only way to access the indoor unit.

Similarly with the outdoor unit, it may cost a bit more initially to get it installed in the most suitable location for system longevity but is usually worth the additional cost.

The outdoor condensing unit is the more costly of the 2 units (indoor vs outdoor), as it is the powerhouse of the whole ducted system.  The easier and more efficiently it can work, the more efficient the whole system is and the more money you save in the long run.  When discussing outdoor unit placement, it’s recommended to negotiate a cool, shaded location if possible and practical.

Ducted air conditioning system costs present significant upfront costs.  It is a real investment in the indoor temperature and climate control of your home or business.  We hope this article has been of use in understanding ducted aircon costs, what to expect, and what to look out for.

However, once your new ducted air conditioner is installed, that’s only half of the story.  Then comes the running, servicing, and repairing of the system, until it reaches end of life and requires replacement.  Stay tuned for Part Two on the topic of ducted AC costs to learn all about the ongoing costs of ducted air conditioning.

It can be a difficult task to find the perfect air conditioner for your business. With so many options in the market, how to choose? You have to think about your commercial premises; is it just a small office? Then you may choose to go with ductless air conditioning. But if you need to cool down several offices, then ducted air conditioning may be the best option for you.

Remember that choosing air conditioning that does not suit your purposes can result in issues like excessive cost, failing to create a comfortable environment, and poor energy efficiency.

Take into consideration that employees that are comfortable while working are more productive, happier, and less stressed. Suitable ducted air conditioning can provide outstanding return on investment.

What is ducted air conditioning?

Ducted air conditioners consist of the outdoor device, which is normally installed outside on the ground, wall bracket, or roof. It is connected to an indoor unit of rectangular shape that goes above the ceiling of a room/indoor area. The two units are connected by refrigerant pipework.

In this way, it will go unnoticed and help ensure the pleasant aesthetics of the office or work space. From here, running off the indoor unit, there will be a series of ducts that are located in the ceiling space running to all rooms/zones.

In each room or zoned area, there will be supply air grille/s, through which air is expelled. There will also be return air grille/s located elsewhere via which air returns to the indoor unit. This ensures proper air circulation.

Many key design elements must be taken into account. For example, all ducted air conditioning equipment requires a control device that often also acts as a thermostat. This is usually placed in the main room or in the hallway, where you can control and operate the ducted aircon.

So, what are the advantages of ducted air conditioning?

There are many factors you should consider before installing ducted air conditioning.

More productivity

Regardless of the weather condition outside the workplace, it will maintain an optimum temperature throughout the indoor workplace. This will lead to people feeling comfortable, thus they will be more productive.

On the other hand, if they feel that their office is really hot then workers will not be focused. This is the last thing you want. Remember that if you are serious about creating a perfect work environment then you need to have aircon to help staff be healthy and productive.

Energy-efficient and thermal insulation

Ducted air conditioning has great thermal insulation and this feature significantly limits the energy consumption of the entire ventilation system. Furthermore, the aluminium coatings present on both sides of the panel ensure excellent waterproofing and vapour blocking performance.

Also, it is proven that ducted air conditioners are capable of reducing your energy consumption. Furthermore, the performance can be higher, even higher than conventional aircon units. Additionally, ducted systems are often the most aesthetically pleasing option you can find in the aircon market.

Uniform temperature

Another one of the great advantages of ducted air conditioning is the uniform temperature. With correct ductwork designed and installed, you can achieve more uniform air conditioning and climate control across the different areas of your office or business space.

The reason for this is that a centralized system allows you to distribute better air through different outlets. In this way, it optimizes its performance compared to a single air outlet where you need higher power or lower temperature to cool down the areas that are far away from the machine.

Capability of zoning

Zoning is amazing if you are going to climatize different offices and areas because not everyone likes the same temperature. Some may feel it is too cold while others may feel it is not cold enough. The temperature battles in offices around the country can be endless. However, zoning can help this.

Not all centralized air ducted systems allow zoning but they are the main aircon type that has this feature and it is an important advantage. You will be able to manage every room independently through the controller. Also, you will be able to close the circulation of hot or cold air by zone if you want to. The degree of control depends on the zoning system in place.

This is a great way of making sure that the power and consequent expenses are focused only on those rooms where people are using the aircon. This lets you save money in the long run as well as preserve the ducted air conditioning equipment.


The air conditioning ductwork is relatively light and it requires few anchor points to install. Thus, it is much safer in case anything falls due to an accident or even earthquake.

Another important advantage in safety terms is the excellent fire resistance. In the commercial setting, R1.5 (fire rating) or higher is often recommended and used, compared to R1.0 in homes.

Useful for summer and winter

Unlike other systems, ducted air conditioners can help you in winter and summer. Reverse cycle air conditioning is standard for ducted aircons. This allows achievement of a perfect temperature with only one air conditioning unit/device.

This is why ducted air conditioning offers you a complete solution for its whole lifespan. This  can be up to 20 years if you give it proper AC maintenance.

What may be some disadvantages?

The ducted air conditioner has a lot of advantages, but it also can have some disadvantages depending on your budget, needs, and location.

If your office does not have the pre-installation of ductwork done, then you will have to include installation of the ducts in the air conditioning installation. This may increase the cost of the complete aircon system and installation.

It is a possibility that your office does not allow you to run refrigerant pipes because of the building structure. For this reason, you may have to reject this air conditioning system type.

Also, investment in ducted air conditioning systems is often high depending on the spaces to be air-conditioned.  However, as we mentioned before, you can save money in the long run because it’s likely that you will be choosing an energy-efficient device and this will reflect in the quarterly energy bill.

Finally, ducted air conditioners have a particularity because in very cold regions it is better not to install them. Otherwise, the air conditioning equipment can suffer and have poor performance when the temperature outside exceeds -5ºC.

This article will go through a few of the key points regarding ducted aircon install cost.  Hopefully by the end you will have some of the answers you were looking for.

If you are trying to decide on who/what/when/where/how to install your ducted air conditioner, such relevant considerations will be explored here.  Read on to learn more about ducted split system costs and what you need to know.

What is split ducted system?

First, before we can start to understand the costs involved, we need to know exactly what Air Conditioning is.  Specifically, what a split ducted air conditioner is.

DX refrigeration cycle

Air conditioning refers to cooling or heating an indoor environment with refrigerant used to transfer heat.  The refrigerant alternates between gas (vapour) and liquid form as it moves through the refrigeration cycle.  Heat is typically transferred directly (direct expansion air conditioning) or indirectly (central air conditioning).

Split air conditioners consist of 2 units; an indoor evaporator unit and outdoor condenser unit.  The units are connected by refrigeration pipework and interconnect cable.  Ducted air conditioners also have the added feature of ductwork supplying air to the indoor occupied space.  Hence the name: Split Ducted Air Conditioning.

AC ducting consists of a series of flexible ducts and associated ductwork that allows air to travel from the central indoor unit out into various rooms/spaces of the building.  This is not to be confused with central air conditioning, which refers to heat transfer via a secondary medium (typically water).

Air conditioner ductwork is typically found the roof, behind the ceiling, and connects to supply air outlets in each room.  However, it is becoming increasingly common for ducts to be exposed, creating an industrial look.

There will also be a return air grille and filter (or multiple) strategically installed in the ceiling to allow air to be filtered and return back to the indoor unit for re-circulation.  The location of this within the home or business is important to ensure the ducted system operates as designed. This is also why cleaning aircon filters is so important.

Ducted outdoor units have great variation, depending on the AC system they are connected to.  Common variations include single, dual or even quad fan, horizontal or vertical discharge, single or three phase, and standard or premium.

Square air conditioning unit on roof

Split ducted indoor units vary also, but not to the same extent as condensers.  Indoor units mainly vary in terms of height (slimline, bulkhead, or standard) and inverter type (standard or premium).  The Daikin ducting AC range provides a great example of the different types of split ducted systems available.  In fact, Daikin ducted air conditioners are amongst the most popular on the market.

The whole ducted aircon system is controlled by a wall controller and/or optional remote controller.  There is often the added option of Wi-Fi control with modern ducted air conditioners and smart zoning systems, like iZone.

What costs are involved in ducted air conditioner installation?

When discussing ducted air conditioning cost, it’s important to understand what installation refers to.  Installation typically refers to the labour AND materials involved in putting in air conditioning.  Basically, everything required for ducted system air conditioning in your home or business except the price of ducted air conditioner units themselves.

You may choose to buy the ducted units yourself or purchase them as part of a package deal from an AC company.  Either way, it’s important to realise that the cost of installation is so much more than just the installer’s wage.

Air Conditioning expert

Ducted air conditioning cost includes, but is not limited to:

  • Installation team, include technician/s, apprentice/s, and electrician where required,
  • Hourly pay rate of all employees involved,
  • Superannuation,
  • Employee days off, including public holidays, annual leave, sick/careers leave, compassionate leave, etc.,
  • Business expenses and overheads, such as vehicles, tools, phones, insurances, licencing, training, advertising, office rent/outgoings, administration staff/equipment, repair/maintenance/upkeep on all items etc.,
  • Ducted unit connection materials, including refrigerant pipework, interconnect cable, joiners, duct tape, etc.,
  • Ducted AC drain materials, including drain, drip tray, safety tray, and p-trap where required,
  • Electrical materials, including isolator, cabling, isolator, circuit breaker, etc.,
  • Coverings such as refrigerant pipework capping, electrical conduit, j-box, etc.,
  • Ductwork including insulated flexible duct (flex), joiners, T-pieces, supply and return air plenums, supply air outlets, return air grille/s and filter/s, etc.,
  • Zoning system including zoned controller, damper motors, zone barrels, cables, connections, sensors (in duct and/or room, where applicable), Wi-Fi components (where applicable), etc.,
  • Freight and transport of all items, including the AC units, materials, zoning gear, etc.,
  • Clean up equipment and materials, including wet/dry vac, chemical spray, wipes, etc., and,
  • Rubbish disposal fees, particularly when old air conditioner units and/or ductwork is being replaced.

When you break it all down, there are more costs involved than first thought.  A good ducted install company will negotiate the best pricing possible from all of their suppliers.  This helps to ensure they can pass on the lowest cost possible to customers.

A good AC company also takes the time to calculate their overheads and minimise and/or spread them out as far as possible.  This also helps ensure the cheapest ducted air conditioning installation possible while retaining the highest quality possible.  After all, no one wants to pay more than they have to for a quality ducted aircon install.

What are reverse cycle ducted air conditioning prices?

Firstly, it’s worth noting that the majority of air conditioners sold in Australia are reverse cycle aircons.  This means that the air conditioning system can provide heating and cooling using the one device.

Good building heat insulation

There is little difference in price between cool only models and reverse cycle models, but the versatility varies dramatically.  Few brands even offer anything other than ducted reverse cycle air conditioning anymore due to popular demand.

The actual cost of ducted air conditioner installation varies dramatically.  This variation is due to 4 key factors:

  1. Installation type – New install or replacement (change over),
  2. Brand of ducted air conditioner – Low, medium, or high-quality,
  3. Installation quality – Labour and materials, and,
  4. Type of zoning system – None, entry level, mid-range, or smart-home based.

With these factors in mind, ball-park figures can be estimated.  However, its important to remember that they are very rough only.

Ducted air conditioning Brisbane supply and install pricing:

  • Small single-story house or studio apartment: $5,000 – $10,000 + GST
  • Standard 2 or 3-bedroom house:  $6,000 – $12,000 + GST
  • Standard 4-bedroom or small two-storey home: $7,000 – $15,000 + GST
  • Standard 5+ bedrooms or double-storey house: $8,000 – $18,000 + GST

Given the number of factors involved and the wide range of ducted aircon costs, it’s always recommended to get a free ducted air conditioning quote based on your specific property, personal preferences, and price range/budget.  A ducted system expert can save you a lot of time, money, and headache in the short and long-term.

Is a zoned air conditioning system required with a ducted air conditioner?

Firstly, we need to understand what air conditioning zoning actually is.  Ducted zoning involves dividing up the area to be served by the air conditioner on paper.  Then, the zoning system is designed to allow separate climate control in each of the distinct areas.  This is applicable to any home or business.

The degree of control will vary depending on the zoned system chosen.  Control can range from basis on/off, to airflow percentage (%) control, all the way up to individual room sensors and even individual room controllers.

The range of features available these days with ducted aircon zoning is amazing.  Touch screens, timers, motion sensors, airflow bypasses, Wi-Fi, and smart home integration, just to name a few!

Air conditioning controls

All the “added extras” obviously cost more, but they are worth investigating.  Some are lovely to have but may not necessarily save you money.  However, the majority of features certainly do save you money when used correctly.  The question is, will the features save me MORE money in the long run compared to upfront supply and install costs?

Unfortunately, there is no simple answer.  It really all depends; on you, your air conditioner, and usage patterns.  This is where it pays to ask an expert ducted air conditioning company what option/s they believe would be worth you considering.

Top 3 Ducted Air Conditioner Installation Tips:

Firstly, smart people do their research.  They chat to the right people, do their own research, and take the time to consider what it the best ducted option for THEM.

During the research, many questions can be directed to ducted air conditioner install companies.  Many people want to know what can be recommend for all aspects of ducted air conditioning.  While there are hundreds of routine questions to be answered, there are 3 top pieces of advice that can be shared to help you make the best decisions about ducted aircon install.

1. The cheapest ducted air conditioning is not always best.

It’s important to remember that you get what you pay for in the world of air conditioning.  You can shop around and find the cheapest ducted air conditioner, but BUYER BEWARE.

There are so many air conditioning mistakes that can be made.  Common ducted AC install mistakes include using the wrong air conditioner size, poor ducted design, incorrect unit locations, use of uninsulated materials (pipework, flex, diffusers, etc.), inadequate drainage systems, dodgy electrics, and the performance of sub-standard or even unlicenced work.

Going with the cheapest ducted aircon install quote you can find may end up costing you more in the long run.  With ducted air conditioning, cheap really can mean nasty, endless frustration, and more money at the end of the day.

2. Timing is important for the best value ducted air conditioner installation

Timing is everything, especially when it comes to ducted air conditioning Brisbane.  It’s recommended to plan ahead, obtain quotes, and choose ducted AC install in the cooler months or shoulder seasons.  It really pays to understand the Brisbane climate, or the climate of your town/region.

You may save significant money as ducted air conditioners often come on sale in the off-peak seasons.  Ducted aircon installers will also have more time to negotiate better pricing with their suppliers and therefore for you.

If possible, avoid looking for ducted aircon install the middle of summer in cities where summer is significantly hotter and/or more humid than other times of the year.  It is also recommended, where possible, to avoid ducted system install in the lead up to Christmas when air conditioning installations are in peak demand around the country.

3. Consider ducted air conditioning zoning

It’s strongly recommended to consider zoning your ducted air conditioner.  Take some time to research the different types of air conditioning zoning available.  Zoning doesn’t come standard with ducted air conditioner units, and often comes from another manufacturer entirely.

Ducted zoning can save significant money, with at least some degree of zoning being recommended.  Zoning system features range from simple on/off buttons, through to energy efficiency bypasses, individual temperature control (ITC) sensors, and Wi-Fi control.  It is well worth weighing up the initial upfront costs with potentially long-term savings and comfort.

Zoning also tends to cost less when installed with ducted aircon units compared to separately down the track.  Current zoning systems may also not be compatible with older models of air conditioner unit.  So, if you are going to zone, it’s highly recommended to do it when the ducted air conditioning system is installed.

Initial supply and installation costs and considerations are critical to ensure you get your ducted aircon installed right the first time.  It is a significant investment, and can be costly to alter once already installed.

There are many factors to consider when it comes to ducted air conditioning pricing.  That is why it’s strongly recommended to get an obligation free, personalised estimate on any business or home ducted air conditioner installation.  The team at Ice Blast are ready and waiting to advise and refine your own ducted air conditioner costs.

When you start a small business, or you are in charge of one, you will have to make many important decisions.

One of those decisions is how you are going to handle the air conditioning in your new location.  There are plenty of options for you, but you need to think strategically.  Take into consideration that you are just starting, so investing a lot of money upfront may not be the best idea.

The most common air conditioning system for a business is ducted air conditioning that usually gets installed in the roof.  But if you want something for a small business, i.e. smaller place but want it to be equally effective, then you should consider acquiring ductless air conditioning.

What is ducted and ductless air conditioning?

Ducted air conditioning works with air conditioning grilles/ducts.  Air is expelled through them and the supply air outlets are distributed around the ceiling.  The indoor unit is connected to an outdoor unit via refrigeration pipework and interconnect cable.

In comparison, a ductless system provides separate heating and air conditioning without the need for ductwork.  You can also combine multiple indoor units to create a multi-zone system.  Indoor units can include wall split units, floor-standing units, ceiling-mounted cassettes, and under-ceiling split units.

Advantages and Disadvantages of Ducted Air Conditioning

Currently, many domestic and commercial buildings have the pre-installation of a ducted air conditioning system.  This would be an advantage when choosing ducted over the other AC types available on the market.

To have ducted air conditioning in your office, your office will need to have these ducts, through which the hot or cold air from a single unit will circulate.  If you don’t have these ducts, then it can be rather expensive to install initially.


Ducted aircon usually enhances the aesthetic of rooms in your office as you will not have to have a large device inside each of these spaces.  Also, the bulk of the system will be covered or hidden behind the ceiling, so people will hardly notice it is there.

Furthermore, ducted units are highly effective if you need to cool many rooms at the same time.  Also, by having a single outdoor unit, maintenance costs can be lower.


In many cases, you will not be able to choose which room to air condition.  This is because ducted devices, without a separate zoning system installed, constantly pump out air when switched on.

The air will come through the ducts and out in all the rooms where there is a grille installed.  This can make you spend more on your business energy bill than you need to.  You have enough expenses already, without adding more.

Also, if your office does not have ductwork or drainage already installed, the investment can be reasonably high if you have to carry out remodelling works.

Ductless Air Conditioning

Advantages and Disadvantages of Ductless Air Conditioner

The first thing you should know is that these devices can have an amazing air conditioner function.  With this, you will be able to obtain a far more comfortable working environment.

There are a range of options available.  For example, the silent ductless portable air conditioner is very easy to install and you will not have to do any expensive renovations or installation.


The main advantage of ductless AC are devices that save half the electricity consumption compared to other air conditioners.  You can switch off units in rooms that aren’t in use rather than continue to heat or cool the whole workplace.

Remember that traditional HVAC systems sometimes develop leaks in the ductwork that can reduce the efficiency dramatically.  You can avoid this problem entirely with a ductless air conditioning system.  Also, they do not usually require as much maintenance, saving you money in the long run.

Constant air circulation by an air conditioner, plus its ability to filter the air, helps to improve breathing.  Ducted AC units can be some of the quietest options of all with fast installation, so you can start operating your new business as soon as possible with no distraction.

Last but not least, you will save a lot of space with these devices.  This makes ductless aircon a great option for a typical small business premises.


The efficiency of ductless AC units can decrease in places where humidity and temperatures are very high.  Also, the air conditioning may not reach everywhere in larger places.

Also, ventilation cannot be integrated into a ductless system like it can be with a ducted system.  Unless you buy the high end Daikin US7, outside air cannot be brought into a central location like it can with ducted HVAC.

Furthermore, you typically can’t integrate humidifiers, dehumidifiers, air cleaning, or air purifiers with ductless air conditioning.  This is compared to ducted air conditioning where you can find these features.

Why ductless air conditioning is beneficial for your business?

Ductless aircon can be ideal for a new business when starting from scratch.  For example, you do not need to install any ductwork.  This will save you time and money, as well as preventing a more complicated installation and maintenance.

Also, it makes it easier for you to control which room you want to air condition.  It is also easy for workers to manage the devices and adjust the temperature to their needs. Furthermore, this will save you money as there are less heat loss and heat gain with a ductless system.

It’s modular, which means that if you need more heating or cooling or your office expands, you will just need to acquire other ductless air conditioner units.  Compare this to the cost of installing more ductwork and materials for the new rooms, if even possible with ducted air conditioning.

How to choose?

Choosing an air conditioning system will depend on many factors.  Factors are linked to the characteristics of the place where you are going to install AC and your specific needs.  These include how many rooms you want to air condition and if you want to cool down/warm up with the same device.

Also, you have to take into consideration how much are you willing to spend on your air conditioning as you can also opt for air conditioning without installation.  This is suitable for consideration in places where temperatures are not so high.

Remember that buying the best air conditioning for your business is an important decision, so please do not hesitate to contact us in case you have any question or need any advice.  We can help find the best solution to match your business needs.

Installing ducted air conditioning is a great idea if you want greater comfort at home for you and your family.  It will also increase the value of your property and make you feel confident that any problem regarding extreme temperatures will be solved.

Remember that air conditioning and heating units can make a huge difference when it is particularly hot or cold outside.  Also, if you have an old unit installed, changing it to a new ducted air conditioning system will result in fewer safety concerns.  You can also find a range of energy-efficient systems in the market to consider and acquire.

However, there are a lot of different types of air conditioning systems to consider.  A decision should be made according to the size of your home, the rooms you want to heat up or cool down, your budget, and other factors that are important to you.

If you are thinking about installing any type of air conditioner, it is a smart move to make sure you do your research first.  By doing this, you will be able to think critically and make a truly informed decision based on your needs and wants.

To help your decision-making process, we will go through six key factors to consider before installing systems like a ducted aircon in your home or business.

What is a Ducted air conditioning system?

A ducted air conditioning installation is made up of an air distribution system.  Air is carried out through a series of ducts usually installed in the ceiling of a home or building.

One of its greatest advantages, therefore, is that it is practically invisible aesthetically.  Typically, the only visible things indoors are the air grilles (in the ceilings, walls or floors) and wall controller.

Ducted air conditioning is controlled via a programmable system.  When strategically and cleverly installed, the ducted aircon will regulate airflow in each room.

These ducted air conditioning systems typically facilitate temperature change through an air-cooled heat pump or fan coil.  Therefore, both energy consumption and efficiency will largely depend on the type of system chosen.

What factors to consider?

The size of your home or building

If your home or business is of significantly size, you should ask yourself if you are willing to make a considerable investment.  This is because the cost of a ducted air conditioning system depends largely on the size and number of rooms you want to warm or cool down.

To do the measurement you have to consider the size of your premises, the size and location of the windows, the height of your ceilings, and even the direction your house is facing.

Furthermore, if you are more conscious of price in the long term, consider the energy costs involved.  Energy expenditure may be the main factor that dictates your use of the AC system.

Residential House Living Room

The airflow and levels of insulation

It is possible to install air conditioning only in certain areas of the house.  However, before considering this, you have to inspect your building, existing airflows, and insulation.

  • Where are windows in each room located?
  • Are you able to use natural breezes at all?
  • Are there areas in your home or business that are cool enough?
  • It is just bedrooms that may need a more advanced cooling and heating system?
  • How are people in the building are able to get warm when they need to?
  • Can you use any of what you already have in place?

This will allow you to select and use a new air conditioner to the full advantage and also help save you money.  Remember to make smart decisions and choose your aircon system wisely.

Perhaps it is not necessary to install a complex ducted air conditioner.  Alternatively, it may be exactly what you were looking for and need.

Also, when choosing an air conditioning system, you must take into account the level of energy efficiency that the installation guarantees.  This includes the air conditioner as well as the associated components.

To achieve greater efficiency, the installed ducts must have proper insulation and airtightness.  This prevents energy losses and guarantees adequate thermal comfort.  This will also help you save energy and money in the long run.

The people and items in each room

Think about all the people that live or work in the building, as well as how they and your belongings occupy the space.

  • How many people use each room every day?
  • What do they do in those rooms?
  • How many hours a day do they spend in those rooms?
  • How much space is furniture and other items taking up in each room?
  • What is the heat load of the items in each room?

This is a great way to help you know exactly how many rooms you need to air condition and to what extent.

The materials the building is made of

The materials used to build your house or office have an impact on the type of air conditioner you will need.  Also, if you are going to install ducted air conditioning, you need significant space in the ceiling.

Furthermore, you have to consider proximity with your neighbours because a large system can produce external noises that your neighbours may have an issue with.  So be sure you have enough space between your building and your neighbours’ for aircon to be installed.

Insulating Rock

Your budget

A ducted air conditioner means comfort, peace of mind, and typically a good return on investment.  However, before installing it, you should ask yourself if you have the budget to make this investment.  Money may not be the main factor, but of course, it is an important one.

If the answer is yes, then you will have to ask yourself (and/or ask the opinion of a professional) three questions;

  • Is this the best solution for your home or business?
  • Will this make your premises more desirable when you go to sell in the future?
  • Is installing ducted air conditioning in keeping with the rest of your building?

Maintenance and cleaning

If you are going to invest in a ducted air conditioning system you must be rigorous about cleaning and maintenance of the system.  This is important because if you do not perform regular maintenance your system may become damaged by dust and harmful particles that can accumulate in the ducts and internal components.

However, you do not have to stress too much about this.  Just having it in the back of your mind and attended to it routinely is often sufficient.  This is because there are modern cleaning method for air conditioning that will help make your life so much easier and help maintain the system.

Remember that regardless of the decision you make, you can not skip the research stage to know what system suits best for you and your needs.  If you need any help in the process, please do not hesitate to contact us.

Depending on your home or business space, you have multiple options when considering a new air conditioning system.

As we always mention, it is essential to make an informed buying decision. That is why if you have been thinking about installing it, you have to know exactly what ducted air conditioning is and how it works.

Also, you have to be aware of the differences between ducted air conditioning and ductless air conditioning, and all the factors involved including price.

Keep in mind that the investment you are going to make is significant, so you want to end up happy and satisfied with your decision.

How to know if a ducted air conditioner works for me?

To choose the best type of air conditioning, you have to take into consideration some important factors like the size and heat load of the area you want to warm up or cool down.

It is also important to know what your budget is and how much you are willing to invest.

Keep in mind air conditioning cleaning and maintenance factors, and also check if aesthetically it will satisfy your expectations.

In the following sections you will find what conditions you need to meet to be able to install ducted air conditioning at home or in a business and a reasonable price guide.

The size of your home or building is really important

For ducted air conditioning, you will pay a price largely dependent on the size of your home or building, how many rooms you want to condition and how many zones you want to run at one time.

Also, you have to consider the size of your windows, the direction the building is facing, your ceiling heights, airflow requirements and heat load (from people and equipment) in every room of the home, office or commercial premises.

Family House with Ducted Air Conditioning

What space do you have available?

Does your house or premises have the space to install ductwork?

If you already have ducts in place, is it easier to just connect new air conditioning units to the existing ventilation equipment?

The short answer is Yes, and it means you will not waste resources and the installation will be easier. This typically means less time and, more importantly, less money that you will have to spend.

It is also important to consider a few questions; How frequently do people use each room? What is each room used for? For how many hours and for how long? By doing this, Ice Blast or any other air conditioning services company can assess if you need ducted air conditioning installed.


With ducted air conditioning, you can choose from two main styles.

The first one is to have the ductwork showing out in the open as decoration. Nowadays, it is trendy to use this style in restaurants and kitchens.

The second option is to hide them behind a solid or suspended ceiling. In this way, you and your visitors will not notice that the ductwork is there.

For ductless air conditioning, it is almost impossible to hide its presence. So, if you want to have something subtle but with maximum potential and high efficiency, ducted air conditioning may be for you.

Sometimes we have a lot of questions regarding different types of air conditioning. This is normal in order to make the best-informed decision for creating an ideal environment in our home, office, or commercial premises.

Take into consideration that it is also important to know what air conditioning is exactly and how it works before going deeper into the matter. In this case, we will discuss what is the difference between Ducted Air Conditioning and Ductless Air Conditioning. The pros, the cons, and we will even help you find the one that suits your needs the best.

What is a Ducted Air Conditioning?

With Ducted Air Conditioning, the heat pump system has an indoor unit and an outdoor unit. The outdoor AC unit usually doesn’t vary very much between different types of Air Conditioning Systems. However indoor units can have many different forms, and in this case it has a connection to ducts.

Normally these ducts get hidden behind a suspended ceiling as it may look ugly if they are not hidden. However, it is also not uncommon to find the ducts exposed and showing out in the open as a decorative part of certain eateries and kitchens going for an industrial look.

How does a Ducted Air Conditioning works?

The Ducted Air Conditioning set up works with a central air system. The indoor unit is connected to multiple ducts in the ceiling. These ducts end with an outlet in each room while the air conditioning is distributed through the ducts. It could be cold air if the system works as a basic air conditioner or hot air if it is also a heat pump.

Don’t forget that for Ducted Air Conditioning System, maintenance and cleaning is a must. You have to clean all the dust and other particles that may disrupt the passage of clean air. By doing this, you will help ensure you do not need to replace it or repair it before expected.

You don’t need to do this on your own. You can call an expert or find out about the best cleaning devices to do it at home.

Ducted Air Conditioning in Ceiling

What’s the difference between Ducted Air Conditioning and Ductless Air Conditioning?

Ducted Air Conditioning works better for large spaces. It provides uniform air conditioning to open environments where you want to have the same temperature throughout the space. On the other hand, Ductless Air Conditioning let you adjust the temperature for multiple individual spaces in large premises.

With Ducted Air Conditioning, air goes from a central air conditioner unit to various rooms through flexible ducts.  With a Ductless Air Conditioner, refrigerant goes directly to the air handling unit/s installed inside the house.

To choose between one or the other you have to take into consideration the following:

  • If you have space for installing the ductwork or not.
  • Control of humidity and dust.
  • The style of your house and desired aesthetics.
  • If you want multiple cooling zones or just one.

It Is possible to have different temperatures in different rooms with Ducted AC?

Zoning is an amazing addition if you want to have Ducted Air Conditioning and at the same time be able to control the temperature in each room. It uses dampers in the ductwork to regulate the air and direct it into the different rooms.

In this way, you have the control to customize the temperature by zone. It will give you more comfort as each room can have its own sensor. When a room reaches the desired temperature, the damper closes to prevent over-cooling or over-heating the room. It opens up when the room temperature needs to be adjusted again.

Zoning certainly has its advantages.  It gives all the family the ability to choose the temperature for their room. It will help you save energy as you can regulate the distribution of air. Also, you can often control the temperature in a digital way via Wi-Fi, with your phone, tablet, or computer.

What are the Advantages and Disadvantages of Ducted Air Conditioning?


Ducted Air Conditioners perform very well and can have high energy efficiency. They work with a single indoor unit, so it is not necessary to install multiple units in different rooms. It is aesthetically pleasing to many when it is installed up out of the way in the ceiling and it doesn’t take up space on the wall.

Easy to install

If you already have ducts and outlets in your home, it is easy to connect the new air conditioner units with the existing ventilation system. Also, it will save you time as the installation is partially done. This is often the case with ducted air conditioning replacement.

Takes the humidity away

If you are concerned about humidity at home, Ducted Air Conditioning can control it better than Ductless Air Conditioning. This is because Ducted AC Units have a greater capacity to remove moisture in the air and drain it away from your home, office or other area served by the system.

The circulation of air is better

Circulation of air works better with Ducted Air Conditioning because the grilles or diffusers (air supply outlets) are distributed in strategic places in the house. With Ductless AC, there isn’t the same ability for the air to flow or circulate.

More stylish

With most components hidden behind a ceiling, Ducted is often better for aesthetic purposes. Alternatively, the ductwork can be exposed to create a trendy industrial look in a contemporary home or stylish café, bar, restaurant, warehouse or other commercial setting.


Expensive installation

If you don’t have any preinstalled ducts or a suspended ceiling, it can be really expensive as you will have to install everything from scratch and gaining access can be labour-intensive.

Expensive maintenance

Maintenance is more expensive for Ducted Air Conditioning, compared to Ductless Air Conditioners, as it has more working components that need attention.  It also requires longer to carry out a standard service as access can be tricky in the ceiling, especially when testing zone motors and checking flexes.

Doesn’t help you with the dust

Ducted AC ducts can accumulate a lot of dust and the distribution of air will be affected by these particles. To prevent this, you may to clean the ducts.  However, a Ductless Air Conditioner doesn’t have this problem.

Harder to clean

Ductless AC units are easier to clean as the indoor air conditioning units are exposed and usually accessible by standing or using a small ladder.  In comparison, Ducted AC indoor units are harder to clean as they are up in the ceiling and usually only accessed via a small manhole. Ducted Systems also have ductwork that may require cleaning, which is a major task best left for AC cleaning specialists.

An extra room

If you decided after an AC installation that you want to add air conditioning to a new room, it is better to have Ductless Air Conditioning in place. Replacing or modifying Ducted Air Conditioning would be more expensive.  Sometimes the Ducted System can not even be modified.  Therefore, there is more flexibility with Ductless AC Units.

Before making a purchasing decision, you have to compare and contrast Ducted Air Conditioning and Ductless Air Conditioning Systems based on your needs, budget, and space.

With these questions answered for you, you will be prepared when the sizzling daytime or freezing nighttime temperatures arrive and it’s time to make a decision.
