$45 (based on raising the temperature from 22 deg C to 25 deg C daily)
Clean air filters monthly A filter that is coated in dust and dirt hinders airflow and reduces the efficiency of the unit, causing it to consume more electricity.
Service at least once a year This maintains the different parts like the pipes and motors, enabling it to run efficiently.
Put up partitions If you have an air-con in your living room, set up partitions to separate it from the dining area so you can cool that space more quickly, and use less energy.
Set a timer Control when your air-con turns off. For example, setting the timer so it switches off an hour before you get up means your room will still be cool – and you’ll be saving an hour’s worth of bills.

Use a fan Switching to a standing fan instead of using an air-con could save you a hefty $790 a year.
