Hot weather alert: there is another hot topic rising together with the temperatures outside: how much energy does your air conditioner really use? Is it very “energy-hungry” compared to other home appliances?

It’s a fact. Australia’s climate is one of the best in the world and one can enjoy pretty good weather throughout the year. However, Queensland’s hot and humid summers could bring about brutal temperatures, so cooling your home is not only a preference but also a necessity.

This is when an efficient air conditioning system makes a difference. Not only you wish for comfort given by the AC cooling effect but also peace of mind when reading the monthly energy bill.

What is the cost of your comfort?

According to a recent survey led by Canstar Blue, many Australian households have cut down on using AC to save money on their electricity bills. To be more precise, 69% of the respondents “blame” their air conditioning for being the largest contributor to electricity bills, while almost half (45%) claim energy efficiency as their number one priority when choosing an air conditioner.

So how much electricity does your air conditioner need in order to keep you cool in summer? Spoiler: it doesn’t need as much as you think it would. Be informed and keep yourself up to date with the electricity prices, plans and deals provided by the Queensland Government – Department of Natural Resources, Mines and Energy. Meanwhile, let’s do some math to find out what is really increasing your power bill.

Understanding your power bill

Energy bills are based on a usage charge for electricity (cents per kilowatt per hour), plus a daily supply charge (cents per day). Check the breakdown on your monthly bill as various terms and conditions may apply depending on the type of contract you have.

Typically, a flat rate tariff is the most common ((Tariff 11 in regional Queensland $0.25kWh) – for residential customers but other options are also available.

Air conditioners vs other home appliances

Based on the electricity prices provided by the Queensland Government, an average reverse cycle air conditioner costs around $0.25 – $0.35 per hour to run for cooling purposes, depending on the size of the room. Therefore, a medium sized room of 36sqm would cost $0.36 – $0.70 per hour to be cooled, whereas large areas (50sqm) would take between $0.70 and $0.95 per hour.

Big energy “consumers”

  • Kitchen appliances – from small microwaves to normal-sized ovens, you can expect to pay up to $1.30 per hour
  • Cleaning appliances – irons, vacuum cleaners and other cleaning devices can cost between $0.40 and $0.80 per hour to run
  • Clothes dryer – “chew up” a lot of energy, starting from $0.50 up to $3.10 kWh


How can you improve your AC efficiency?

There are many ways you can save money on your electricity bill by cutting down the electricity your AC takes up. Check out some useful tips and tricks to make your air conditioner energy efficient.  Here are a couple of the most effective ones:

  • Look for the Energy Rating Label and choose a high Star Rating
  • Ask for the DRED program from your local energy provider
