6 Best Air Conditioners in Australia of 2021

Australian summers. Bl**dy scorching one day, hot as Hades the next.

If the only way you keep cool is jumping under the sprinkler in your jocks, well, mate, it’s time to air condition your home. And possibly start saving for the kids’ future therapy.

We can’t help you with the therapy, but we can help you find the best air conditioners in Australia for your budget and lifestyle.

But with all the brands, sizes and features on the market today, finding the ‘best’ air conditioner can be hard yakka.

Of course, you’re not a complete tight ar*se and won’t go with the cheapest one you can find. Imagine the ear-bashing you’ll get when it stops working! I mean, you get what you pay for, right? 

But you do want value for money—a unit that will cool and heat your home effectively and efficiently.

Especially when you consider how much more you may have to dish out to the power company. Plus, you may like your unit to feature all the bells and whistles that make life just that little bit easier.

Welcome to Hello Breeze, where we’ve done the hard yards for you. We’ve got a list of different brands and product ranges so that you can choose the best budget air conditioner, the best unit for a small or large room, or the most energy-efficient.

But first, let’s have a gander at what you need to consider before forking out your hard-earned bucks for a new unit.

What You Need to Consider?

Room Size

Finding the right-sized unit to suit your space is crucial to its efficiency. Choosing a unit that’s too small or too large will not only affect performance but will be reflected in your power bill. Spoiler alert—wobbly chucking ahead.

This guide will help you choose a suitable air conditioner capacity for your room size.

Room sizeExampleCapacity
Up to 20m2Bedroom, study, small kitchen2 to 2.5kW
From 20 to 40m2Bedroom with an ensuite, small lounge2.5 to 5kW
From 40 to 60m2Large bedroom, mid-sized lounge4 to 6kW
60m2 and aboveOpen-plan areas, large lounge5 to 9kW

But what happens if you don’t hit the ‘Goldilocks’ size?

Too big

The unit may repeatedly run short cycles to achieve the desired temp. Which means:

  • The room becomes too hot or too cold
  • The unit doesn't dehumidify the air enough and leaves you feeling clammy
  • A surge in power, which increases running costs 
  • Faster deterioration on the system
Which is the best air conditioner for your room's size?

Too small

An undersized unit may have to run at max power more often. Which means:

  • The unit dries out the air too much, which affects, eyes, nose and skin
  • More wear and tear on the system
  • Increased power use 

We recommend you choose a model with a capacity that's either just right or slightly higher than you need. For example, let’s say you want to cool the little nipper’s room which is 20m². So, according to the guide, you would choose a unit between 2.0 and 2.5kW. We recommend you upsize slightly and go with the 2.5kW model.

Noise

Some systems can generate a bucket-load of noise, which can be super annoying if you’re working or sleeping. A noisy outdoor unit can also p*ss off the neighbours.

Noise level is typically measured in decibels (dBA). Most standard air-con units operate between 40 and 60 dBA.

Not sure how to measure decibels? Let’s put it into context. Watching the news at an average volume—not Grandad volume—usually produces around 60 dBA, and our regular indoor voices reach about 40 dBA. 

How to choose the most quiet air conditioner?

So, if your air-con operates at 60 dBA, it could very well interfere with your convos or your Netflix binge. The quietest units are around 19 to 24 decibels—comparable to the sound of a desk fan.

With the models we’ve listed below, we’ve included a dBA range. The lower number is the unit running at low speed, while the higher number reflects the unit on turbo.

Your Location

Where you live can affect the size of air-con you need. For example, North Queenslanders would need a more powerful air conditioner for cooling than the same sized room in Tassie. You’ll also need to consider the orientation of your room’s windows. West or north-facing windows can let in a sh*t load of summer heat. Whereas a south-facing window will be cooler, requiring less energy to cool the room.

If you don't have roof insulation, consider installing it. Not only will it save you money on your power bill in the long run, but you can get away with buying a smaller, cheaper air conditioning unit.

Energy Efficiency

All new air conditioning units come with a Zoned Energy Rating Label (ZERL). The ZERL provides a seasonal efficiency rating for three Aussie climate zones. 

The three climate zones for Australia are:

  • hot, 
  • average, and 
  • cold.

This label is designed to help you choose a product that is suitable for your climate zone. Ratings run up to 10 stars for both heating and cooling. Clearly, the more stars, the more energy-efficient your AC unit is. 

What Type of Air Conditioner Should I Get?

Common types of air conditioners in Australia are split systems, evaporative coolers, and gas ducted systems.

types of best air conditioners

Split Systems

The most popular type for Aussie homes is the split system and are commonly found in the more humid spots. These energy-efficient little numbers are ideal for one room or an open-plan space up to 60m2. However, they’re not suitable for extra-large rooms or double-storey properties.

Multi-split Systems

This is simply a split system with one outdoor unit connected to two or more indoor units. Multi-splits are ideal for two or three rooms within cooee of each other.

Ducted Air Conditioning

Ducted reverse cycle air conditioners are super-efficient systems that work by sending hot or cold air through your entire home via a series of ducts installed in your roof or floor. In addition, you can add zoning control to adjust temperatures in individual rooms. Ducted reverse cycle air cons cool down rooms quickly in all climates—especially humid areas.

Evaporative Cooling

With evaporative cooling, a fan within the outdoor unit draws in fresh, dry air from outside across wet cooling pads. The water then evaporates, resulting in cool, filtered air, which passes through vents to selected rooms of your home. This type of cooling is perfect for homes located further away from the equator.

Righto. Now you should have a better idea of what you need and what features to look for. Here are our recommendations for the five best air conditioners in Australia.
