Your air conditioner
Reverse cycle ducted systems
The average ducted air conditioning system uses 6,000 watts of electricity every hour which means a running cost of around $1.80 per hour. If your air-con is running constantly during a hot spell (for 24 hours), this could add up to $43 day to your electricity bill for each hot day. And for cooling, the lower the temperature setting - the higher the bill!
Split systems
If you have split systems for your home, the average running cost can range from 30c an hour for a small 3KW system up to 65c an hour for a large 7KW system.
This may not sound like much, but if your air conditioner is running for 8 hours a day over summer, your electricity bill for a mid-sized unit could be $468 just for the 3-month summer period - and if you have more than one split system running, it obviously adds up to much more over the year.
Ducted evaporative system
The cost to run a ducted evaporative air conditioning system depends on a few things, including the size of your home and the efficiency of the system. On average, it can cost anywhere from $300 to $800 per year based on an average electricity cost of 30c/hour.
Savings tips
-
Pedestal fans generally use a lot less electricity- and you might want to open your house at night if the breeze is blowing - but make sure your home is secure.
-
Close the blinds or curtains to keep out the heat.
-
Consider installing outdoor blinds to keep out the sun.
-
You could also have your windows tinted.
-
Make sure your air conditioning system is the right size for your room/home.
-
Set your air-conditioning thermostat to 24°C in Summer (and 18°C in Winter) and only use it when you really need it. Air conditioners set below 24 degrees in summer will add 5-10% to the running cost.
-
Make sure your air conditioner gets an annual service to keep it running efficiently.

Your tumble dryer
Although it may seem like the simplest solution on a hectic day, pulling clothes straight from the washing machine and throwing them into the dryer is not the most cost-effective or energy-efficient approach.
-
