Discover the shocking cost of running your air conditioning during summer

As the sun shines bright across Australia, so does the cost of keeping our homes cool.

With energy prices soaring in recent years, many Australians are left wondering if the comfort of air conditioning is worth the hefty price tag.

This concern has only been amplified since the 20-25 per cent energy price hike (depending on the provider) that took effect across large parts of the country on July 1, 2023.



To shed light on this issue, Compare the Market conducted an analysis of the costs associated with different types of air conditioners and fans.

Chris Ford, a representative from the organisation, noted that many households are still unsure about how to stay cool without breaking the bank.

'Electricity prices have surged higher than they've been in the last couple of years, and that's due to a range of factors, but one of the main reasons is because we're too reliant on coal and we're transitioning to renewable energy,' he explained.

'While switching to greener energy will permanently drive down power bills and keep them lower, we don’t have enough of it yet.'

'But families shouldn’t suffer through the heat to save money, they just need to be smart about their usage and ensure they’re on a competitive plan.'



Various factors can impact a household's energy bill, including the frequency of use, the size and capacity of the air conditioner relative to the area being cooled, the energy-efficiency rating of the appliance, and the energy retailer's usage rates.

All these factors can result in an energy bill that’s a bit too much for already strained budgets. So, how can we save where it counts?

According to Ford, one of the most cost-effective ways to keep cool is by using fans.

The Department of Climate Change, Energy, the Environment and Water estimates that it costs approximately 2c/hour to run a fan.

However, the more fans you use, the higher your electricity bill will be.



On the other end, the most expensive air conditioning unit analysed by Compare The Market was a large Reverse Split Unit.

The Fujitsu Reverse Cycle Split System reportedly costs about $1038.40 a year to run.

'Window box air conditioners came out as one of the most expensive options of those we analysed,' he explained.

'While a little outdated, they're still common in many apartments and smaller homes.'

'These units typically have a lower energy star rating, which is why they can cost more to operate than ducted or reverse split units,' Ford explained.

The Gree C5.3kW Cool Only Box, a window box model analysed in the study, costs $758.85 a year to run.



Regardless of the type of air conditioning unit you have, Ford emphasised that usage habits can significantly impact your energy bill.

He recommended setting the temperature around 25 [degrees Celsius] on warm days.

'Be aware that for every degree cooler you set the temperature, you could be increasing your electricity usage by 10 per cent.'

'That really adds up if you’re running more than one system at a time.'

Ford also shared several tips to help Australians save money on their energy bills:
  • Know the size of the room you’re looking to cool. When you go to a supplier or retailer, it pays to know the room’s length, width and ceiling height for a single unit or space of the house for the air conditioning system.
  • Make sure your home is adequately insulated. Ceiling, wall and floor insulation can have a massive effect on air conditioning.
  • If your home has a lot of windows that let in light and heat: shut blinds and curtains, install outdoor awnings and close doors and windows. These are all cheaper alternatives.
  • If your home is equipped with solar panels, remember that running the air conditioner during the day when your system generates power could lower your overall bill.
  • Make sure you are on an electricity plan that is affordable and think about comparing your current plan against others.
Key Takeaways
  • Running air conditioning in the summer can significantly impact electricity bills, especially since energy prices have recently spiked.
  • Compare the Market's analysis, which highlighted the cost differences between various air conditioning units and fans, with fans being a more cost-effective cooling option.
  • The Fujitsu Reverse Cycle Split System was cited as one of the most expensive air conditioning units to run, costing approximately $1038.40 a year.
  • Chris Ford from Compare the Market suggested setting air conditioners to 25 degrees Celsius and cautioned that each degree cooler can increase electricity usage by 10 per cent.

We run our bedroom air conditioner on 25. We run our big air conditioner that covers the kitchen, dining and lounge area on 29. We turn both split system units off at the outside unit when not using cos they still use power even when you're not using it. Never leave your split system outside units on. Another save money tip we were told was to get those old fashioned draft roll things and put them in front of the doors. Before we put the air con on in the lounge room we go around and put those door draft things in front of EVERY closed door. Another tip we were told is close the curtains if you're running the air con during the day or from late afternoon. It also helps cool the room. We live in north Queensland and it's been terribly hot this summer. We put up with the heat all day and don't put our air conditioner on till around 1/4 to 6. Drink cold water as it helps you feel less hot. Regularly wash your face with cool water to not feel as hot.

outdoor awnings are very expensive. Our house is well insulated and we have ceiling fans We only use the AC on very hot days or cold days in winter. I had a quote for awnings or security screens a few years ago and it was going to cost many thousands to cover two large windows, the ones which face west and get the afternoon sun. One of the guys who quoted me was aggressive and came across as dodgy, wanting me to sign up immediately. I didn’t proceed but wish there was a cheaper alternative.

29 glad i do not live in your house.
 
I have been told that if you run the air conditioning on dehumidifier mode it is a lot cheaper to cool your home than on the cool mode

We are considering getting ducted reverse cycle air conditioner for the whole house. I know that costs can be high, but if we zone our house properly, we can hopefully keep the costs down. Most of our day is spent in the family room, kitchen and dining room, so that will be one zone. I am not sure how practical this is, but we have to do it to keep relatively comfortable in our house.

Beware of devices that claim to save 70% off your power bill. The only to reduce you bill is to use less power. An appliance that uses 100 watts of power when switched on will always use 100 watts of power while switched on. To save power switch off power points, especially remote controlled devices that use standby power.
Fuel saving devices are another scam and also ultrasonic pest control devices. They are all useless. RESEARCH these items before considering buying them. In the end they just cost you more money.

We had our Rev. Cycle A/C updated late last year & is the best outlay we ever made.

Our Installer recommended using a "airtouch CONSOLE (Powered by Android)". We can set Low, Med or High fan speeds or Auto. Heating, Cooling, Fan or Auto. We have 5 zones, Family / Kitchen, Theatre & Spare bedroom (rarely used & kept @ 10% each to circulate air), Bed 1 & Bed 2. Each can be set separately on the touch control panel for fan speeds between 0% & 100% & temp for individual comfort. The outside unit l believe is Samsung.

Our unit runs 24/7 in these temps up to 42°C on 24°C during the day & 22°C @ night for weeks on end. The filter is cleaned by hosing outside @ least every 7-10 days. The fan % is adjusted for comfort in each room. The old A/C always seemed to labour & was extremely noisy whereas this is quiet. Electricity costs for a quarter can be a bit more than $250 for 3 adults.

Not sure if this helps with your decision. Best wishes with this.
 
If you believe that BS about renewable energy then you are a fool, the cost of it and distribution will amount to trillions,nuclear, gas and clean coal, which we have an abundance of all, is the only way to drop prices, but we're stuck with a moron in Bowen, so we're going to all pay big time for his stupid ideology.

Thanks Ezzy. I does help to hear of other people's experiences. The retailers will sell you anything and tell you anything, so research is critical.
Have a great day.
