Air conditioners keep us cool in Singapore’s hot weather. But have you ever wondered how much electricity they use? Understanding your aircon’s energy usage can help you save money on your monthly bill. This is where something called kWh comes in.
What is kWh?
Let’s start with the basics.
kWh stands for kilowatt-hour. It tells you how much electricity your aircon uses. For example, if your aircon uses 1.5 kW and runs for 4 hours, it will use 6 kWh (1.5 × 4 = 6).
This number helps your electricity company know how much to charge you. So, knowing how many kWh your aircon uses is a smart way to watch your energy costs.
How Many kWh Does an Aircon Use?
The amount of electricity your aircon uses depends on a few things:
Type of aircon – Wall-mounted, cassette, or ducted
BTU size – Bigger BTU means more power
How long you use it – More hours = more energy
Efficiency – Energy-saving models use less
Here are some simple examples:
A 9,000 BTU unit may use about 0.9 kWh per hour
A 12,000 BTU unit might use 1.2 to 1.5 kWh per hour
Big units like ducted systems may use 3 to 5 kWh per hour
How to Know Your Aircon’s Cost
Now, let’s see how it affects your bills.
Here’s how you can figure it out:
Your aircon uses 1.5 kWh/hour
You use it for 6 hours a day
Electricity costs $0.30 per kWh
Daily cost: 1.5 × 6 × 0.30 = $2.70/day
Monthly cost: $2.70 × 30 = $81/month
Of course, this is just an estimate. Your bill can go up or down based on how often and how well your aircon runs.
Easy Ways to Save Electricity
Luckily, there are many ways to save energy while staying cool:
Clean the filters – Dirty filters make your aircon work harder
Use the timer – Don’t leave it on longer than needed
Get regular servicing – A clean unit works better
Close your windows – Keep the cool air inside
Choose inverter models – They save more power over time
To sum it up, your aircon’s kWh usage affects how much you pay every month. The good news is, with smart habits and regular maintenance, you can stay cool and save money too.
