Set your air-con no lower than 21 to 24 degrees

You could reduce your energy costs by setting your air-con to the recommended temperature: That’s 21 to 24°C in summer, depending on where you live.


Air-cons account for up to 40% of the average household's energy costs

Here are some tips to run your air-con as efficiently as possible. 
  • Put your fan on first to push the hot air out. The air flow created by a fan can feel like the equivalent of reducing your temperature by around 3°C - but fans use less energy and are cheaper to run.
  • Then turn your air-con on a little earlier in the day and, depending on where you live, set it to around 21 to 24 degrees. Each degree lower (in summer) or higher (in winter) can increase your power bill by up to 10%.
  • Don't forget! Close any rooms you aren't using so you don't cool them unnecessarily, or block off the ducting outlets in unused rooms if you have a ducted system.
  • In colder months, setting the temperature between 18˚C to 20˚C is comfortable for most people.

  • Water heating
    Tips to reduce your water heating costs...
    • Reduce the amount of water and electricity you use by having shorter showers and installing a water saving shower head.

    • Consider fitting flow restrictors to your bathroom, laundry and kitchen taps to reduce the amount of water that comes out.

    • Take advantage of the sun's free heating by installing a solar hot water system and placing it close to where most of the hot water is being used.
  • Kitchen & laundry
    • Set your fridge temperature between 3°C and 4°C and your freezer temp between –15°C and –18°C.

    • Check the seals on your fridge door for air leaks. If you can slide a $5 note in the door frame, air is escaping – and energy is being wasted.

    • Dustbust the back of the fridge. Vacuum the dust from the condensor coil at the back of the fridge to help keep it running efficiently.

    • Defrost the freezer if the ice is thicker than five millimetres so your freezer can use less electricity to keep your food frozen.

    • Consider if you really need your second fridge. If you don't use it much, keep your drinks in the main fridge and just turn your second one on when you're entertaining. Or better still, use ice buckets.

    • Only run your dishwasher when it’s full and use the ‘eco’ setting to lower its energy and water use.

    • Regularly clean your dishwasher filter to keep it running efficiently.

    Washing machine & dryer
    • Wash with cold water and use the ‘eco’ setting to use less energy. Washing in warm or hot water uses around 50% more energy than washing in cold water - using a typical front loader machine.

    • Use your washing machine less by waiting until you have a full load.

    • Avoid the dyer. If you use your dryer regularly, it can account for up to 10% of your energy use.
  • Lighting & appliances
    Reduce your lighting costs...
    • Swap out your old lightbulbs for LED bulbs which use less watts to provide the same amount of light. LEDs use 75% less power and can last up to ten times longer than standard globes.

    • Get in the habit of turning lights off when you leave a room – or use natural light during the day when you can.


    Appliances (like TVs & game consoles) 
    • Standby mode can account for up to 6% of your energy use. Your fridge and freezer need to stay running all day and night – but your TV, gaming consoles and microwave could be using electricity when they’re not in use, so remember to swicth the off at the wall. 

    • Consider investing in a standby power control board to detect when an appliance is on standby and cut the flow of electricity automatically.
  • Swimming pools
    Tips for an energy efficient pool...
    • If you have a pool, set your pump on a timer. Running your pump for two hours less a day in winter could help you save on energy costs - always follow the manufacturer’s instructions.

    • A clogged filter means your pump needs to use more energy. Scoop leaves by hand, keep filters clean (or backwash as required) and make sure your filter is the right size for your pool.
  • Maintenance
    By keeping your appliances in good working condition - like cleaning or changing filters - you could save hundreds a year.
    • Clean the filter on your air-con and you could save about $300 a year.
    • Check the seals on your fridge and freezer doors. If a five dollar note can fit between the seals, then cold air is leaking out and hot air is getting in. This means your fridge is working overtime and costing you money.
    • Vacuum the dust from the condenser coil at the back of the fridge - it could lead to an energy saving of 11%.

Consider these energy-saving investments

Here's some helpful online resources if you're ready to upgrade appliances or invest in your home's energy efficiency

Solar hot water

Consider switching to a solar hot water system. They cost more to buy than other options but are generally cheaper to run and better for the environment. 

Hot water systems

Cooling & heating

Check your home’s insulation is adequate, install quality window coverings and use energy-efficient appliances.

Cooling & heating tips

Buying an appliance?

Check its energy rating. The more stars the appliance has, the less energy it will use – which will save you money in the long term.
