Here’s the Quick Answer:
Ceiling fans use far less electricity than air conditioners. Depending on the model and speed setting, a ceiling fan may use around 5 to 75 watts. A split-system air conditioner may draw around 500 to 2,000 watts or more while operating.
At an example electricity rate of 35 cents per kWh, a 75W ceiling fan costs about 2.6 cents an hour or 21 cents over eight hours. A 2,000W air conditioner costs about 70 cents an hour or $5.60 over eight hours.
Use this formula to estimate the running cost of your appliance:
Watts ÷ 1,000 × hours used × electricity rate per kWh
Actual costs depend on the appliance, speed or temperature setting, room conditions and electricity tariff. Check the wattage label and your electricity bill for a more accurate estimate.
| Appliance | Example power use | Cost per hour | Cost over 8 hours |
|---|---|---|---|
| DC ceiling fan | 5 to 30W | 0.2 to 1.1 cents | 1.4 to 8.4 cents |
| AC ceiling fan | 35 to 75W | 1.2 to 2.6 cents | 9.8 to 21 cents |
| Split-system aircon | 500 to 2,000W | 17.5 to 70 cents | $1.40 to $5.60 |
Example costs use an electricity rate of 35 cents per kWh. Your actual tariff and appliance power use may differ.

To understand how air conditioners and ceiling fans work we need to know how electricity is measured and paid for. This means understanding the basics of electricity usage. It shows how our choices affect our bills.
Basics of Electricity Consumption
Electricity consumption is measured in kWh. It’s a combination of power and time. Here’s a simple breakdown:
- Watt: The basic unit of power
- Kilowatt: 1,000 watts
- Kilowatt-hour: The energy used by a 1 kilowatt appliance in an hour
A 100 watt ceiling fan running for 10 hours is 1 kWh.
From Energy Consumption to Bills
Your energy use directly translates to your bills. In Sydney the average cost is around 35.3 cents per kWh (Source – Canstar Blue). Find your own cost here:
| Appliance | Power (Watts) | Usage (Hours) | Energy (kWh) | Cost (AUD) |
|---|---|---|---|---|

Understanding these basics helps us compare air conditioners and fans efficiency. It helps us make a smart choice and lower our bills.
Air Conditioners
Air conditioners are a big part of keeping NSW homes cool. This will go into the different types of air conditioners, their power usage and what affects their efficiency.
Types of Air Conditioners
For home use there are types of air conditioners:
- Reverse cycle: These do both cooling and heating for all seasons.
- Non-ducted: For individual room cooling, also known as split systems.
- Ducted systems: Cooling the whole house through a hidden duct network.
Average Power Consumption
The power an AC uses depends on the room size and how often it’s used. Let’s look at some cooling costs in Sydney over a year:
| Room Size | Annual Cooling Cost |
|---|---|
| Small | $61 |
| Medium | $101 |
| Large | $154 |
| Ducted Systems | $300+ |
Factors Affecting Air Conditioner Performance
Performance of air conditioning units depends on:
- Room size: Bigger rooms need more cooling power.
- Climate: Warmer areas need more cooling.
- Usage: More use means more power consumed.
- Insulation: Good insulation keeps the cool air in.
- Maintenance: A well serviced unit performs at its best.
Understanding these factors helps you choose the right air conditioner. It also helps you optimise performance which can save you power.
How Much Power Does a Ceiling Fan Use?
Ceiling fans are a popular choice for Australian homes because they are cost effective. We go into the world of ceiling fans, types, energy use and what works best.
Types of Ceiling Fans
There are two main types of ceiling fans: DC and AC powered. DC fans lead in energy savings and are quiet. AC fans are cheaper upfront but less efficient.
Ceiling Fan Wattage and Electricity Cost
A ceiling fan’s electricity use depends on its motor, blade size and speed setting. As a general guide, many DC ceiling fans use around 5 to 30W, while many AC models use around 35 to 75W. The lowest speed normally uses less power than the highest setting, so check the wattage shown on the fan’s product label or manual before calculating its running cost.
| Motor Type | Hourly Cost (cents) | Summer Cost (90 days) |
|---|---|---|
| DC Motor | 0.17 – 0.90 | $1.22 – $6.48 |
| AC Motor | 0.57 – 1.90 | $4.10 – $13.68 |

Practical Recommendations
We’ve collected some practical tips for saving energy in NSW. By following these strategies, you can stay cool without breaking the bank. This helps keep your energy usage efficient.
When to Use Air Conditioners
Using your AC wisely is key in hot spells. Start when the thermometer hits 35°C. Aim to keep your space between 24-26°C for the best balance during summer. Close off doors and windows to lock in the cold air.
When to Use Ceiling Fans
Ceiling fans are a great choice during milder weather. They should be running when it’s 22-28°C outside. For a cool trick, remember to run them in a counterclockwise direction. This mimics a gentle breeze and makes the room seem cooler, letting you dial down the AC.
Both Together
AC and ceiling fans is the way to go. It’s cool and power saving. Here’s for your home:
- Set your AC a notch higher than usual
- Let the ceiling fans circulate the air
- Switch between AC and fans depending on the outside weather
