Aircon Energy-Saving Tips for HDB and Condo Homes
Practical ways to lower your aircon electricity bill in Singapore without giving up comfort.
Settings
- Set the temperature to 25°C.
- Use a fan with the aircon so you can set it a degree or two higher.
- Use the timer or sleep mode at night.
Home
- Close curtains on west-facing rooms in the afternoon.
- Seal gaps under doors of air-conditioned rooms.
- Keep the outdoor unit in the shade with space around it.
Maintenance
- Dirty filters and coils make the compressor work harder. Service every 3 months.
- Low gas makes the unit run longer for the same cooling. Fix leaks early.
- When replacing, choose an inverter model with a high energy-efficiency rating.
