Tenaga Nasional Berhad (TNB) uses a tiered pricing system where the cost per kWh increases as you use more electricity. This means heavy AC users pay more per unit.
TNB Domestic Tariff (2024)
| Usage Tier | Rate per kWh |
|---|---|
| 1 - 200 kWh | RM 0.218 |
| 201 - 300 kWh | RM 0.334 |
| 301 - 600 kWh | RM 0.516 |
| 601 - 900 kWh | RM 0.546 |
| >900 kWh | RM 0.571 |
Tips to Reduce AC Energy Costs
- Regular maintenance: Dirty filters and coils make your AC work harder, using more electricity
- Optimal temperature: Set AC to 24-25°C instead of lower - each degree lower increases energy use by ~6%
- Inverter technology: Inverter ACs are 30-50% more efficient than non-inverter models
- Right sizing: Undersized AC runs constantly; oversized AC cycles too often - both waste energy
- Fan assistance: Using a ceiling fan allows you to set AC 2-3°C higher for same comfort
AC Wattage by Size

| 1.0 HP | ~750W | 0.75 kWh |
| 1.5 HP | ~1100W | 1.1 kWh |
| 2.0 HP | ~1500W | 1.5 kWh |
| 2.5 HP | ~1900W | 1.9 kWh |
| 3.0 HP | ~2300W | 2.3 kWh |
