Frequently Asked Questions
How much does it cost to run an aircon in Singapore?
A 1.5 HP standard aircon running 8 hours/day at S$0.28/kWh costs approximately S$26–30/month. An inverter model of the same size can reduce that to S$18–22/month.
What is Singapore's electricity rate?
SP Group's regulated tariff is approximately S$0.28/kWh as of 2025. If you are on the Open Electricity Market (OEM), your rate may differ — check your bill.
How much can I save with an inverter aircon?
Inverter aircons typically save 25–40% compared to standard non-inverter units. A household running aircon 8 hours/day can save S$30–60/month by switching to 5-star inverter models.
Should I service my aircon to reduce electricity costs?
Yes. A dirty aircon filter and coil reduce airflow efficiency, causing the compressor to work harder. Regular servicing (every 3–4 months) can improve efficiency by 10–15%.
