Best Temperature for Air Conditioning In Summer Australia

Summer is the best time to enjoy the outdoors and go to the beach! If you’re staying at home without an air conditioner, you’ll probably feel sticky, irritated, and uncomfortable through the summer months. As summer approaches, you may want to consider preparing yourself for the upcoming heat waves by levelling up. With climate change making the weather even more unpredictable, heatwaves are becoming a more common occurrence. That is why it’s important to have air conditioning at home to beat the summer heat. However, having an AC unit is just one part of keeping your house cool. One important factor often overlooked is choosing an appropriate temperature for air conditioning during hot summers in Australia. It’s important because you don’t want to compromise either your comfort or your energy bills.

Beat the Heat!

Beat The Heat

If you’re just sitting around in your house, sweating away, summers can be a real disaster. Old and outdated air conditioning units can lose energy efficiency but over time, some of their parts may stop working so your air conditioner is no longer as energy efficient. Replacing an old air-conditioning unit with a new one can give you the chance to enjoy your summer without the risk of getting heatstroke from the sweltering Australian temperatures. Some of the benefits of air conditioning in summer are outlined in the next few sections.

Better Indoor Air Quality

Hot air can cause a lot more than just headaches. It can also cause a whole host of health problems such as allergies, asthma & respiratory issues. Those with asthma and other respiratory problems find that cool, purified room air from an air conditioner maintained at the right temperature helps them manage their symptoms. Conversely, very cold room temperatures can be troublesome for people with respiratory ailments too. Heat can also cause heat exhaustion, especially for those with heart-related medical issues. Therefore, maintaining an optimal indoor environment, including air quality and temperature, is essential.

Reduced Humidity

Reduced Humidity Mould

Summer in Brisbane is famous for its hot & humid summers. Moisture is the presence of water in the air, and when there is too much humidity, it can cause a variety of issues in your home, including mould. Mould and mildew growth is more common in homes with high humidity or improper moisture control. When the humidity levels are too high, it can cause many health concerns, including allergies, asthma, and other respiratory issues. In extreme cases, some types of mould can cause long-term chronic health problems or potentially death.

It can also be really annoying because it makes you sweat a LOT. Because there’s already so much moisture in the air, your sweat doesn’t evaporate. To solve this problem, set your air conditioner to a comfortable temperature & allow it to remove the excess humidity from your home. Not only will this keep the humidity down, but it will also ensure you can wear your favourite shirts without sweating all over them.

Ultimate Comfort for You and Your Family

Sweating profusely in very hot weather may cause you to become dehydrated. You may not feel like working if you’re feeling overheated. It becomes even more difficult when you have seniors and children at home. When you’re in such a situation, keeping your home at an optimal temperature becomes very important for your overall mental and physical well being.

Choosing the Optimum Temperature for the Entire Day

Some of the problems discussed above arise when you do not know this: what is the best temperature for air conditioning in summer Australia? To guarantee your comfort, choose your air conditioner temperature wisely. When trying to decide what temperature to keep your air conditioner working at, it is important to ask these questions.

What temperature feels right for you?

What temperature is cost-effective?

Of course, deciding the best temperature depends on your personal preferences and needs, and it is not a ‘one size fits all scenario. If you do need to know a range, however, we suggest it should be anywhere between 23ºC-25ºC. Determining the best temperature for air conditioning will require you to experiment with different temperature settings. It also depends on whether you are looking for some savings, higher comfort levels or a mixture of the two.

Other factors that can play a role in determining the best aircon temperature are the number of people living in the house, the amount of direct sunlight your house receives and your general health condition (and issues, if any).

Ideal Temperature for Sleeping

Ideal Temperature for Sleeping

Your ideal temperature for sleeping largely depends on your preference but always take into account the outdoor temperature. For example, there’s no point setting your air-con on cooling at 25ºC if it’s only 24ºC outside – in this case, it may be better to open up the windows. A Brisbane summer night can be somewhat cool yet still very humid, so we suggest setting your air conditioner at least 1-2 degrees cooler than the outside temperature. This will ensure your system runs & helps to remove humidity from your home throughout the night.

You can also use ceiling fans under normal (summer mode) settings to ensure that cool air from your air-con is evenly distributed throughout the rooms and you do not end up with warm and cool spots throughout the home.

Invest In a Reverse Cycle Ducted System

Investing in a good ducted air-conditioning system will ensure you never have to worry about being trapped in heat again! Simply install a reverse cycle ducted air conditioner that works to cool your house optimally during summers. These systems are flexible because they can reverse the refrigeration cycle anytime to provide heating & cooling through a smart thermostat to provide the ultimate level of comfort. Some advantages of using ducted air conditioning in the summers are:


  • Cost-effective – Not only do these air-cons dehumidify and filter your air, but they are also proven to be a budget-friendly option for anyone looking to add more value to their house. Running costs in the long-term are fairly minimal and maintenance is not a hassle either, making ducted air cons the perfect choice for homeowners seeking energy efficiencies with long-lasting durability.
  • Noiseless – Because of their ability to be discrete and noiseless, ducted air cons make it so much easier for you to fall asleep at night. Conventional air conditioners such as split systems can be noisy, plus they diminish the overall aesthetic appeal of the room. With ducted air-cons, you do not have to worry about either of the two problems. With their ducts discretely fixed in the ceilings and within walls, you never have to worry about your room looking cluttered again.


Safe and Purifying – As mentioned earlier, reverse cycle ducted air-cons are unobtrusive, so you will never have to see overhanging wires or large indoor units ruining the look of your living space. Moreover, some also have special in-built filters that purify the indoor air, such as Panasonic’s nanoeX Air Purification System, so whether it be day or night, you are always breathing clean, dust-free air.
Investing your money in reverse cycle ducted air-cons from companies like Panasonic, Mitsubishi Heavy Industries, Fujitsu & LG ensures that your money is well spent. With their anti-corrosive materials and super budget-friendly deals, you can easily get your ducted air-cons installed in no time at all! Not only that, these companies specifically design their air-cons to suit the weather conditions in Australia to cool your house on the hottest of days.

Install Temperature Sensors for Optimal Efficiency

If you want to save money, install wireless temperature sensors on your ducted system. These devices measure the temperature inside your home and send signals to your thermostat, which adjusts the temperature in each zone accordingly. They’re easy & relatively cheap to install and can help you reduce electricity bills by up to 10%.

If you live in an area where temperatures fluctuate frequently, then installing temperature sensors can prove extremely beneficial. You will be able to adjust your thermostat in each zone to provide an improved comfort level according to the changing weather conditions without having to manually change settings all the time.

Try Split Air Conditioning

If you are not ready to jump on the reverse cycle ducted air-con bandwagon yet, then split air conditioners is another option available. Split air conditioners offer zone-wise air conditioning which means you can cool only one room at a time. This can be beneficial for someone living alone, but not so much for a family as it becomes too heavy on your wallet having to install multiple units around your home. Bridging the gap between a traditional window air conditioner and the ducted air systems can prove to be a viable option for cooling your living area.

Limitations of Split Air Conditioners

Limitations Of Split Air Conditioners

Even though split air conditioning systems present an opportunity for homeowners to cool their individual rooms, they also have some disadvantages which might deter you away from them. Split systems cannot be optimally utilized by families since their area coverage is zonal. So unless you want to be cramped in a room with the rest of your family, or end up installing separate units for each room, this does not represent a very practical choice. The zonal effect can also be achieved by using ducted air cons, so splits might not be as great an option for a one-person dwelling as we might think. They can also make the room look messy with their outer units as well as the ones installed inside the room. You may require a permit for installing the outdoor unit and the manufacturer warranty is deemed void if a non-licensed person installs it for you. Moreover, the initial costs of running a split air conditioner can be 30% more than a ducted air conditioning system, which might not fit in everyone’s budget either.
