Mid-range split-system air conditioner
Unlike window or wall units, split-system air conditioners are quieter and more energy-efficient. They also have a sleek design that seamlessly blends into your home's aesthetic. With hundreds of options in the market, finding the right split-system AC can be a grueling task.
When choosing a split-system air conditioner, always consider your budget, the size of the space where you plan to install it, and whether you want a reverse cycle or cooling-only model. Other features you should look out for are noise levels, fan speeds, demand response enabling devices (DRED), operating modes, and controls.
The team at Finder has evaluated numerous split-system air conditioners to make your buying decision easier. We examined models from brands such as Kelvinator, Panasonic, Samsung, Mitsubishi Heavy Industries and Fujitsu. We also considered customer reviews and ratings plus key features when selecting models for each category, bringing you what we believe as the 10 best split-system air conditioners you can get right now in Australia.
Read more detail on our methodology below.
Mitsubishi Heavy Industries is the clear winner in the split-system air conditioning category, with top scores across the board. Consumers said the brand was the best for quietness, performance, features, functions and value for money.
The Fujitsu 7.1kW Reverse Cycle Split System Inverter Air Conditioner DRED Enabled has secured high acclaim among its users with an impressive rating of 4.7 out of 5 stars on Appliances Online. It's also our pick for the best overall split-system air conditioner available online.
It has an extensive roster of features. This includes everything from the Demand Response Enabled Device (DRED), weekly timer, a long-life Ion deodorisation filter, and an automatic louvre to an innovative human sensor.
Designed to foster comfort and efficiency, the system boasts an Economy mode and All DC for added energy savings. Unique features such as the Blue Fin heat exchanger and Apple-catechin filter contribute to its longevity and superior air quality.
Nevertheless, like any product, this has a couple of cons to consider. First, the Auto-changeover feature might need some getting used to, as it switches modes based on temperature changes, which might not always align with individual preferences. Additionally, the Human sensor feature may not always accurately detect movement, leading to unnecessary energy consumption.
In the 2023 Finder Retail Awards, we surveyed over 34,000 Australians about their retail purchases to discover which were their favourite brands across 170 product categories and over 1,200 total brands.
For air conditioners, Fujitsu was ranked 6th for value for money, 1st for performance, 4th for ease of use, 6th for cleaning and maintenance and 5th for product features.
8 brands were rated across these decision criteria.
We recommend the Panasonic Reverse Cycle Inverter Split System CS/CU-Z35XKR as the best energy-efficient split-system AC.
With a cooling capacity of 3.5 kW and a heating capacity of 4.0 kW, it promises optimal comfort through all seasons. A noteworthy aspect is its inverter technology, an innovation that significantly enhances energy efficiency. The product has earned an impressive 4.6 out of 5 stars on The Good Guys, speaking volumes about its quality and performance.
This model boasts a 4-star energy rating for cooling and 6.5-star for heating, which translates to substantial reductions in energy consumption and, consequently, lower electricity bills. The Nanoe-G air purifying system further adds to its appeal, ensuring cleaner and healthier air indoors.
However, it's important to note that there are certain areas where this model falls short. It lacks an auto shut-off function, which would have added a layer of convenience and further energy savings. Additionally, the absence of an anti-dust filter means the air circulated may not be as clean as it could potentially be with that feature.

The Mitsubishi Electric Reverse Cycle Inverter Split System 3.5KW/3.7KW MSZAP35VGKIT has an outstanding 5-star rating across Bing Lee, Harvey Norman, and JB Hi-Fi. That's why it's our top choice for the best split-system AC for bedrooms.
With a cooling capacity of 3.5KW and a heating capacity of 3.7KW, it's well equipped to maintain a comfortable temperature, regardless of the season. The unit also boasts a 3.5 energy rating for cooling and an impressive 4.5 for heating, demonstrating its efficiency.
Plus, the unit uses R32 refrigerant, which is more efficient than older kinds. It also has a dual barrier coating surface, reducing dust and greasy dirt from collecting in the air conditioner. This means you can enjoy clean, fresh air without worrying about maintenance.
This unit also has new vertical and horizontal vanes, double the size of the previous model. This allows for better airflow control and adjustable airflow direction for maximum comfort.
However, the unit may not be sufficient for cooling or heating larger spaces, and it may struggle to maintain the desired temperature in rooms larger than the recommended size. Some users also found it noisy, which may concern light sleepers.

Our team recommends the Kelvinator Reverse Cycle Inverter Split System 9KW/10KW KSD90HWJ as the best choice for effectively conditioning large spaces.
With a 4.3-star rating on Appliances Online, this unit delivers high-performing, energy-efficient cooling and heating. The DC inverter technology ensures maximum energy efficiency with minimum noise, perfect for large, open areas.
Coupled with the Kelvinator Connect feature, seamless unit control from any location becomes a reality, courtesy of the Kelvinator Home Comfort App. Plus, with the clean-face fascia, dust build-up on the front of the unit is minimised, making it easy to maintain.
The 24-hour timer allows you to program the unit to turn on and off automatically, adding convenience to your daily routine. The Auto Air Swing feature enables automatic distribution of cool or warm air throughout your space by directing it up and down.
But note that the KSD90HWJ model lacks a detailed user manual, which might present a steep learning curve for some users in accessing all the unit's features. Additionally, the unit's DRED network cable could require the services of an expert electrician to safely and properly install.
26% off Kelvinator 7.1kW Split System Reverse Cycle Inverter Air Conditioner
The Mitsubishi Electric Reverse Cycle Inverter Split System 3.5KW/3.7KW MSZAP35VGKIT is our pick for a compact yet powerful air conditioning option. This system has an impressive 5-star rating across major electronics retailers like Bing Lee, Harvey Norman, and JB Hi-Fi.
Its weekly remote controller technology puts full control at your fingertips, providing a range of functions, including ON/OFF capability, set temperature adjustments, mode changes, fan speed, and airflow direction adjustments. Furthermore, this unit seamlessly integrates with Wi-Fi control, Amazon Alexa, and Google Assistant, ensuring a connected and convenient user experience.
The MSZ-AP Series maintains a uniform design across all its models and sizes, which may not suit those seeking a unique aesthetic. Additionally, while its streamlined design is engineered to blend with any decor, some users might find it overly simplistic or unappealing, potentially clashing with more eclectic interior design styles.

The Kelvinator 2.5kW Split System Reverse Cycle Inverter Air Conditioner KSD25HWJ DRED Enabled is an excellent, affordable choice for those on a budget.
Rated 4.15 out of 5 stars on Appliances Online and Bing Lee, this air conditioner boasts a multitude of features, such as the Kelvinator Connect for remote operation, DC inverter technology for energy efficiency, and a 24-hour timer for scheduling convenience.
Plus, with the clean-face fascia design, cleaning becomes a breeze as it minimises dust build-up on the front of the unit. The Auto Air Swing function ensures even distribution of cool or warm air throughout the room, while Sleep mode automatically adjusts temperature for maximum comfort and energy savings during sleep.
In case of a power outage, the unit will restart with the same settings thanks to the Auto Restart feature. For added convenience, the KSD25HWJ is equipped with an RJ45 Demand Response connection socket, allowing for demand response control by your electricity provider.
Note that its relatively small heating and cooling capacities of 3.2 kW and 2.5 kW, respectively, might be insufficient for larger spaces. Additionally, it tends to become noisy at the highest settings, which could be disruptive.

With a rating of 5 out of 5 stars on Bing Lee, we picked the Hisense HAWV24KR 7kW Split System Reverse Cycle Air Conditioner as the best mid-range option.
Its silent function ensures a peaceful environment, free from the constant hum associated with many air conditioning systems. This unit has a cooling capacity of 7.1 KW and a heating capacity of 7.7 KW, ample for maintaining a comfortable indoor climate. It's also equipped with HI-NANO, an efficient Plasma ion technology that generates ions faster than ordinary plasma. This, along with Wi-Fi connectivity that allows control through the Hisense ConnectLife app, enhances the user experience.
But despite its 3.5-star energy rating for cooling, the unit only manages a 2-star energy rating for heating, indicating that it may consume more power during colder weather. And although the unit self-cleans reduces the need for maintenance, some consumers have reported minor issues with the self-cleaning function.
It features a cooling capacity of 9.4 kW and a heating capacity of 10.3 kW, decidedly capable of maintaining a comfortable indoor climate under varying conditions. The model is highly applauded for its corrosion-resistant heat exchanger and human sensor technology.
There is also no need to manually switch between heating and cooling modes, as the auto changeover function seamlessly transitions between the two. Plus, the advanced Anti-Dust Filter effectively removes harmful particles from the air, making it an excellent choice for those with allergies or respiratory conditions.
This model has a Sleep Mode to ensure energy efficiency during rest hours, and it also comes with a timer and remote control for convenient operation. The Auto Up/Down Swing Louvre feature allows for even air distribution throughout the room. At the same time, the Auto Restart function ensures that the unit resumes its previous settings after a power outage.
Despite a handful of advanced features, it's worth noting that the system lacks an oscillating louvre, which could limit the distribution range of conditioned air. Additionally, with an energy rating of 2 for cooling and 2.5 for heating, there are other models in the market with higher energy efficiency.
In the 2023 Finder Retail Awards, we surveyed over 34,000 Australians about their retail purchases to discover which were their favourite brands across 170 product categories and over 1,200 total brands.
For air conditioners, Fujitsu was ranked 6th for value for money, 1st for performance, 4th for ease of use, 6th for cleaning and maintenance and 5th for product features.
8 brands were rated across these decision criteria.
The Haier Reverse Cycle Inverter Split System 5.3KW/5.5KW AS53PDDHRA-Set is our top pick for the quietest option you can get right now in Australia.
With an indoor sound level of at least 33 dB, it is the quietest option available, ensuring a peaceful ambience for work, relaxation, or sleep. This system also has an impressive arsenal of features, including UV light for airborne hazard elimination, a self-clean model for indoor and outdoor units, and Wi-Fi-enabling for smart home integration with the SmartHQ app.
But the system may prove a bit challenging to install for those not technologically inclined, considering its smart home integration features. Also, while the 60°C sterilisation mode effectively sterilises the indoor unit, it might slightly increase energy consumption.

8 brands were rated across these decision criteria.
The Fujitsu 9.4kW Cooling Only Split System Inverter Air Conditioner DRED Enabled ASTG34CMTA is our pick for those looking for a cooling only split-system AC.
It has a bevy of excellent features, such as low noise operation and multiple program modes (Auto, Cool, Dry, Fan) with 4 fan speeds plus auto selection. The unit is a Demand Response Enabled Device (DRED) – a significant advantage for energy-conscious consumers.
Plus, the unit's auto restart function is particularly endearing, as it recalls exact settings after any power failures. Additional features like a human sensor, weekly timer, and sleep timer enhance user convenience, whereas the washable panel and long-life ion deodorisation filter ensure clean, breathable air. And don't forget about the Apple-Catechin Filter, which works diligently to remove fine dust, mould spores, and harmful microorganisms.
Despite its higher price point than some competitors and the need for regular filter cleaning, the Fujitsu 9.4kW unit's unmatched performance and advanced features make it an investment worth considering.

We started our search for the best split-system air conditioners by finding the highest-rated products on productreview.com.au, The Good Guys, Harvey Norman and Appliances Online. We compared models from the following brands:
We then compared these products against other highly rated air conditioners in the same category. In addition, to review ratings and comments (as of September 2023), we also considered capacity, energy efficiency, ease of use and price to help us finalise our top picks.
When comparing split systems, consider the following key factors:
Split-system air conditioners are generally pretty quiet but some models are loud enough to disrupt sleep or cause neighbours to complain. If you can, test out the noise levels in store or read user reviews before purchasing.
Also, check if there are any local council noise restrictions on air conditioners or strata rules for those living in apartments.
Look for an AC with multiple fan speeds and a large airflow range. This will help cool down your room quickly when needed and can also keep the fan low once the room is the right temperature.
A wider range of fan speeds will also help reduce noise on low settings.
If your AC model comes with DRED (also known as PeakSmart) and your energy provider uses the PeakSmart service, you can automatically switch to economy mode during peak energy periods. This reduces your power usage and saves you money.
Not all energy providers offer this service. If your current provider doesn't, consider switching energy providers.
An auto mode and an energy-saver mode can help you save money on heating energy by ensuring the air conditioner is only on when you need it to be. If you live in a humid area, look for a model with a dry or dehumidify setting.
Newer models can often connect to your Wi-Fi so your AC can be controlled from your smartphone. This can be handy when you want to turn off your AC when you're out or want to keep an eye on the temperature remotely. While this function is usually built-in, some models require you to install a controller device.
An aircon that can automatically sense when you're in the room and can lower the AC when you're out could be a big energy saver. While different brands use various terms for this function, such as motion sensor or people detector, they serve essentially the same purposes.
For those living in an area with extreme temperatures, it's important to check the operating range of your chosen aircon before purchase. A typical air conditioner can operate in temperatures from about -10°C up to 45°C.
Choose from a wide range of air filters that could help remove odours, mould, dust, allergens, germs and smoke from the air. For those with asthma or allergies, it may be best to pick a HEPA filter.
If you live in an area with extreme cold, look for a model with automatic de-icing to avoid frost build-up on the heat exchanger coils of your outdoor unit in winter.
Split-system air conditioners are more effective at cooling a home than large air conditioners.
A split-system air conditioner consists of 2 parts: an indoor unit and an outdoor unit connected by ducts holding refrigerant gas. The system works together to cool large rooms or multiple rooms.
Split systems need to be installed by a professional technician so make sure to factor installation costs into your budget.
There are 2 main types of split-system air conditioners: single-split and multi-split. The right type for you depends on the layout of your home and the area you want to cool.
Another way to differentiate air conditioners is by how they are mounted. You can choose a wall mounted, ceiling mounted or floor-mounted unit.
Most split systems have reverse cycle capability. Reverse cycle refers to the ability to both cool and heat. In cooling mode, a split system removes heat from the inside and transfers it outside using refrigerant gas stored in the pipes that connect the indoor and outdoor units. In heating mode, the reverse occurs: heat is taken from outside and transferred indoors.
While reverse-cycle systems can be one of the cheapest ways to heat your home during winter, if you already have another heating system in place or only experience mild winters, you may want to purchase a cooling-only aircon instead, which will cost you less.
It's important to pick the right air conditioner size for your room size. If your AC is underpowered, it will run at maximum output too often, which can cause excessively dry air and premature wear. On the other hand, if your AC is overpowered, it will run recurrent short cycles, which will rack up power usage – and your electricity bill – and cause the room to become too cold or hot while causing greater wear and tear.
The right sized air conditioner for a room depends on the local climate, room type, shading and insulation. The size and orientation of the windows or glass panels should also be taken into consideration.
The following general suggestions can help you work out what capacity your room will need:
| Room size (sqm) | Minimum recommended Kilowatts |
|---|---|
| 10-20 | 2-2.8 |
| 20-40 | 2.8-5 |
| 40-60 | 5-6 |
If you're unsure, opt for an air conditioner with a capacity on the higher side.
1. There's a right time to buy your AC
It's best to avoid purchasing your aircon during peak season, which will be during summer or mid-winter for colder areas. There could also be a delay getting your aircon installed professionally during these times. Instead, wait for the end of season when you're more likely to grab bargains on old models or buy your AC just before the peak season begins to beat the crowds and get your AC installed quickly.
2. Installation is required
You'll need to have your aircon installed by a professional, licensed air conditioner installer. You should look for one with ARCtick approval and compare quotes before deciding on one. Some installers will package the unit together with the installation service, while for others you'll have to get the unit yourself first.
3. Don't forget about maintenance
You'll need to clean your air conditioner filters regularly and service it from time to time. Keep your outdoor unit out of direct sunlight.
