Hot tips to cool your home this summer – and avoid ‘bill shock’

There’s nothing like an Aussie summer to turn up the heat, but are you ready for the subsequent bill shock?

Canstar Blue have compared running costs for a range of common cooling products. Then they’ve compared the increased electricity cost you’re likely to face, depending where you live in this wide brown land. This sunburnt country, a land of sweeping plains, if you want to get poetic.

So, hold on to your hat, because the following is not always pretty reading…

Whole-house, ducted air-con costs most

Results of the cooling product running price comparison range from the sublimely cheap – a modest 2 cents per hour for ceiling and pedestal fans – to the expensively ridiculous.

Namely those with whole-house, ducted air-conditioning can expect to pay $2.45 per hour – averaging $882 more on power bills over three months.

A standard split-system air-conditioner costs 25 cents to run per hour, with a three-month bill coming in at $90. Portable air conditioners are more expensive, having a running cost of 45 cents per hour.

State by state, estimated summer electricity bills range from the lowest in Victoria – $387 for a split-system air-conditioner – to the highest in South Australia at $638.

In ascending order of price, the states rank: Victoria, Queensland, ACT, NSW,South Australia.

Ducted, whole-house air-conditioning costs $1,179 in Victoria, and peaks at $1,430 in South Australia. That’s some Summer bill shock!

Use your air-conditioning conservatively

However, there are ways to maximise the efficiency of your cooling system(s) over summer.

  • Close windows, curtains and blinds during the day to avoid the house heating up with hot outside air.
  • Turn ducted cooling off in rooms that you don’t use.
  • Run your air-conditioner at the highest temperature you can tolerate (i.e. 26 rather than 18).
  • Close doors to avoid losing cool air when running a portable air-conditioner. These are best used to cool one room at a time.
  • Buy air-conditioners with high star and efficiency ratings.
