Aircon Australia: Choosing the Right System Made Easy

Choosing the right air conditioning system for your Australian home can be overwhelming, especially with the many options available. There are over 30 different types of air conditioning systems on the market.

In Australia, the climate varies greatly from north to south, with some areas experiencing extreme heat and humidity. This makes it essential to choose a system that can efficiently cool your home and handle the local climate.

For example, in tropical regions like Darwin, a heat pump system is a good option, as it can provide both heating and cooling. In contrast, in cooler regions like Melbourne, a ducted system might be more suitable.

Split systems are perfect for apartments, bedrooms, or living rooms where zoned cooling is sufficient, and are simple and quick to install. However, they only cool one area at a time, so multiple units are required for whole home cooling.

Here's a quick comparison of the main types of aircon systems:

There are several types of conditioning systems to choose from, each with its own strengths and weaknesses.

Split system air conditioners are one of the most popular choices in Australia, especially for cooling a single room or open plan space. They're energy-efficient and affordable to run, making them a great option for apartments, bedrooms, or living rooms.

A split system consists of two main components: an indoor unit and an outdoor compressor connected by pipes that carry refrigerant. This setup is ideal for cooling a single room or open plan space, and can be installed quickly and easily.

Split systems are also available in multi-split configurations, which allow for multiple indoor units connected to a single outdoor unit. This is perfect for households where family members have different comfort preferences, such as cooling bedrooms at night while keeping the living room off.

Here are some key benefits and drawbacks of split systems:

Ducted air conditioning systems are another popular option, particularly for larger homes or office spaces. They use a central unit that distributes cooled or heated air through a network of ducts into each room via discreet vents.

Ducted systems are the ultimate solution for homeowners who want seamless, silent, and whole of home climate control with minimal visual impact. They can be zoned to control airflow in specific areas, improving energy efficiency.

However, ducted systems do come with a higher upfront cost due to the complexity and scale of installation. They also require sufficient roof or underfloor space for ducts.

Here's a comparison of the two main types of conditioning systems:

Portable aircon systems are a great option for rooms where a built-in system isn't feasible, such as if you're renting.

These units are usually single and can be moved from room to room as needed, but they're not always easy to move.

They often have a flexible duct that must be attached to a window to vent the heat outside, which can be a bit of a hassle.

Portable aircon systems are generally not as efficient as split-systems, but they can still be effective.

You can find portable aircon systems in a price range of $300 to $1100, which is relatively affordable.

Some recommended models cost under $1500, so you don't necessarily need to break the bank to get a good one.

It's worth noting that the power of the aircon system you need can vary depending on your location, with rooms in hotter cities like Perth requiring more powerful units.

Most air conditioners can operate in temperatures from about -10°C up to about 45°C or more.

If you live in a hot and dry climate, an evaporative cooler can be a cheaper alternative to an air conditioner.

Australia's diverse climate means that some regions may require air conditioners that can handle extreme temperatures, so it's essential to check the operating range before you buy.

An evaporative cooler can be a great option for hot and dry climates, but it might not be suitable for areas with high humidity.

Choosing the right air conditioner system for your home can be a daunting task, especially with the numerous options available in Australia. You'll need to consider the size of your home and your budget to make an informed decision.

For most homes, a reverse-cycle split-system air conditioner is the best option, as it can both heat and cool your space. This type of system is the most popular in Australia, and for good reason - it's efficient, effective, and can be installed in various rooms.

When it comes to determining the size of your air conditioner, it's essential to consider the room size and calculate the required capacity. A rough guide suggests the following capacities for different room sizes:

However, it's crucial to note that this is just a rough guide, and you should aim to choose a model with equal or slightly greater capacity for the room. This will help prevent issues such as frequent short cycles, inadequate dehumidification, and increased power consumption.

Split system air conditioners are a great solution for Australian homes because they offer efficient cooling with minimal power consumption.

They also provide affordable heating during colder months, making them a versatile choice for households with varied climate needs.

Modern AC units feature smart inverters and sensor technology to ensure maximum efficiency and efficient cooling, providing year-round comfort.

A multi-split system is a great option for homes with multiple rooms that need cooling, but don't require a separate system for each room.

It's essentially a split-system with one outdoor unit connected to two or more indoor units, making it perfect for two or three rooms that are reasonably close together. You can get about the same price as installing separate split-systems, which is around $600-$5500 per system, not including installation.

With a multi-split system, you can cool multiple rooms at once using a single outdoor unit, and each indoor unit can be controlled independently, allowing for personalized comfort. This is especially useful for households where family members have different comfort preferences.

When choosing a fan, consider the fan speeds. A model with a wide airflow range is ideal, allowing you to adjust the fan to your needs.

A fan with multiple fan speeds is a must-have. This will enable you to switch between high and low speeds, making it easier to achieve the perfect temperature in your room.

Having multiple fan speeds also means you can reduce noise levels once you've reached the desired temperature. This is especially useful for bedrooms or living rooms where you want a peaceful atmosphere.

A very high fan speed can help cool down a room quickly, making it perfect for hot summer days.

Your air conditioner has several operating modes that can be adjusted to suit your needs.

In Auto mode, the air conditioner automatically chooses the mode required to keep the room at the chosen temperature. This is a convenient option that saves you the hassle of constantly adjusting the settings.

Cool mode pumps heat from the inside to the outside, cooling the room. This is a straightforward way to bring down the temperature.

Heat mode, on the other hand, pumps heat from the outside to the inside, warming the room. This is perfect for chilly mornings or evenings.

The Dry mode dehumidifies the air, providing some cooling but not as much as cooling mode. This is useful for humid climates or when you want to remove excess moisture from the air.

Fan only mode blows air without heating, cooling or drying, which is great for when you just want a cooling breeze.

Economy mode, also known as Eco mode, reduces power consumption. This can be implemented in different ways by different brands, but it's always a good idea to look for this feature if you're concerned about saving energy.

Here are the operating modes in a quick reference list:

Adjustable or oscillating louvres are a game-changer for directing air to where it's needed. You can adjust them to point up for cool air or down for warm air, and many models allow you to do this via the remote.

Left and right adjustability is also a feature of many models, helping you target specific areas with the airflow.

Noise is an important consideration when choosing an air conditioner. Most modern split-system air conditioners are very quiet indoors and out.

The noise levels of air conditioners can vary, ranging from 19dB to 53dB from indoor units and 42dB to 69dB from outdoor units. For comparison, a quiet home typically has a sound level of around 30dBA.

A noisy indoor unit can be a nuisance, interfering with activities, conversation, or sleep. On the other hand, a noisy outdoor unit can disturb you or your neighbors.

Here's a rough guide to common sound levels for reference:

Local councils often have noise restrictions related to air conditioner use, so be sure to check council regulations before buying.

If you live in a cold area, get an air conditioner with automatic de-icing to avoid frost building up on the outdoor heat exchanger coils in winter. This feature is especially important for regions with harsh winters.

Most air con models can operate in temperatures from about -10°C up to about 45°C or more, which is sufficient for most parts of Australia.

All air conditioners come with a dust filter in the indoor unit, which traps dust from the air as it circulates through.

This filter is mainly to stop dust from clogging up the internal workings, but it has a minimal effect on smoke and other very fine particles.

You really need a HEPA filter to filter out smoke, but they can't be practically fitted to split-system or ducted air conditioners.

Many new air conditioner models have an air purification feature, typically based on ionisation or photocatalytic filters.

Be cautious with aftermarket air purifying filters, as they may not have been thoroughly tested with every air conditioner brand.

Using non-genuine parts may reduce your air conditioner's performance, possibly cause damage, and could void your warranty.

A reverse-cycle air conditioner can heat as well as cool – in fact, it's one of the cheapest ways to heat your home in winter.

Most cooling-only and reverse-cycle models aren't very different for cooling efficiency, but the models that score best in our test for cooling efficiency all happen to be reverse-cycle models.

Even if you only use heating occasionally, you're better off getting a reverse-cycle model in most cases.

Reverse-cycle models come with smart inverter technology, making them a cost-effective choice for Australian homes that experience both hot and cold conditions throughout the year.

If you only need an air conditioner for cooling in summer, then a cooling-only air conditioner could be right for you. They're generally cheaper than reverse-cycle models but usually have all the same features.

Split system air conditioners, which are a type of reverse-cycle model, offer efficient cooling with minimal power consumption, and affordable heating during colder months.

Installing an air conditioner in Australia requires more than just plugging it in – you need to make sure it's done right to ensure it runs efficiently and safely. Look for a licensed installer with ARCtick approval and electrical qualifications to wire your air conditioner into your home.

As you're choosing your installer, keep in mind that they should also be qualified to handle the plumbing aspect of the installation, such as connecting the drain to your home's stormwater system. This is crucial, as improper installation can lead to costly repairs down the line.

When it comes to installing the compressor, make sure it's on a firm base or attached to a wall with sturdy brackets, and protected from direct sunlight. The outdoor unit should also be installed on a firm base or attached to a wall, ideally with about three to five meters of pipes between the two units.

Here are some essential maintenance tips to keep your air conditioner running smoothly:

By following these simple tips, you'll be able to enjoy a cool and comfortable home while also keeping your energy bills under control.

When choosing a mount type for your air conditioning unit, there are several options to consider.

The high wall mount is a popular choice, allowing the unit to blow airflow easily across the room. This can be a great option for larger spaces.

For smaller rooms, a floor-mounted unit may be a better fit.

You can also consider a cassette mount, which is installed in the ceiling. This can be a good option if you have a room with a low ceiling.

Some units are versatile and can be mounted on either the ceiling or the floor, offering flexibility in installation.

Here are some common mount types to consider:

Installing an air conditioner in Australia is a big decision, and it's essential to consider the installation costs. The price of installation depends on several factors, including the size of the system, the type of property, and the complexity of the work required. The installation costs can range from $1,500 to $15,000 AUD or more, depending on the type of system and the size of your home.

If this caught your attention, see: Aircon Unit Size

For example, a split system can cost anywhere from $1,500 to $3,000 AUD, while a ducted system can cost between $8,000 to $15,000 AUD or more. It's always recommended to request a free site inspection and detailed quote from a certified installer to get an accurate estimate.

To ensure long-term performance and energy efficiency, regular maintenance is key. Cleaning filters every 1-2 months, scheduling professional servicing once a year, and checking for blocked vents and cleaning ducts in ducted systems every 2-3 years are essential tasks.

Here's a quick rundown of the maintenance tips:

Remember, good maintenance not only prolongs your system's life but also keeps your energy bills under control.

An air conditioner should last at least six years, and they frequently last 10 years or more.

Most brands offer five-year warranties, while some manufacturers, like Hitachi, offer six years and Teco offers seven years for certain models during promotional periods.

Don't forget, you're still covered by Australian Consumer Law regardless of the manufacturer warranty.

Solar-powered air conditioners have been tested, with one category failing and being removed from sale due to instability when operating at 75% of its solar array's capacity.

Energy efficiency is a major factor when selecting the right air conditioner. TCL split system air conditioners are built with smart inverters that regulate power consumption based on your cooling needs, reducing energy use and saving you money.

The higher efficiency of modern reverse cycle air conditioners means lower environmental impact and reduced electricity bills, with maximum comfort.

A quarter of the entire electricity network is only needed for a few hours on very hot days so that people can run their air conditioners, which is being paid for by everyone. This means that households who don’t have an air conditioner are effectively cross-subsidising those that do by A$350 each year.

Even a model with one or two stars is still OK, but a model with five or six stars (or more) is clearly better, though the more efficient model might also be more expensive. The more stars, the more efficient the model and the less it should cost to run, assuming it's been correctly installed.

To make your air conditioner usage more environmentally friendly, you can insulate your home, only use the air conditioner when you really need to, and run it on your own solar power, if that's an option.

Here are some key facts about energy efficiency and costs:

The old star rating label had one rating for cooling and one for heating, but any model registered from April 2020 onwards has a more detailed star rating label, known as the Zoned Energy Rating Label (ZERL). This shows three cooling star ratings and three heating star ratings, based on the climate zone where the unit is installed.

If you're in the market for a new air conditioner, it's worth considering the top brands in Australia. Mitsubishi Electric is a strong contender, with a 72% rating in one review.

Mitsubishi Heavy Industries and Daikin are joint winners of the Best Brand for air conditioners in 2025, each with a 74% rating.

To determine the Best Brand, CHOICE uses a combination of factors, including average test score, brand reliability, customer satisfaction, and recommended ratio. Here's a breakdown of the criteria:

It's worth noting that while some brands may have more recommended models, they may fall short in other areas, such as test scores or reliability. ActronAir products, on the other hand, are designed and manufactured to Australian standards, offering the best zoning options in the country.
