| 201–300 kWh | 33.4 sen |
| 301–600 kWh | 51.6 sen |

## Inverter vs Standard AC — Is the Upgrade Worth It?

Standard AC (3-star)

-   • Fixed-speed compressor
-   • Higher electricity consumption
-   • Lower purchase price
-   • More temperature fluctuation

Inverter AC (5-star)

-   • Variable-speed compressor
-   • Up to 30–40% energy savings
-   • Higher purchase price
-   • More stable temperature

In Malaysia's year-round cooling climate, an inverter unit typically pays back the price premium within 2–3 years.
