Tips to Reduce Aircon Electricity Costs
Set to 25°C
Every degree below 25°C increases energy consumption by ~3%. Set 25°C and use the fan for circulation.
Use Inverter Technology
Inverter ACs modulate compressor speed instead of switching on/off — saving 25–40% electricity.
Service Regularly
A dirty filter can increase energy consumption by 5–15%. Service your aircon every 3–6 months.
Use Timer Function
Set your aircon to switch off 30 minutes before you wake up — room stays cool without running all night.
Frequently Asked Questions
What is the current electricity rate in Singapore?
SP Group's regulated tariff is approximately S$0.28/kWh (varies quarterly). Open Electricity Market (OEM) retailers may offer different rates. You can update the rate in the calculator to match your actual tariff.
How much does it cost to run a 1.5 HP aircon in Singapore?
A standard 1.5 HP (3-star) aircon running 8 hours/day at S$0.28/kWh costs approximately S$100–S$120/month. An inverter model can reduce this by 25–30%.
Is an inverter aircon really worth the extra cost in Singapore?
Yes. In Singapore's climate where aircon runs year-round, an inverter unit typically pays for itself within 2–3 years through lower electricity bills. It can save S$25–S$40/month versus a non-inverter unit.
