Why is the electricity bill so high in Nha Trang (and how to reduce AC costs)?
Based on 2 discussions with 2 participants · Last activity: 18 days ago
TL;DR
Electricity in Vietnam is billed on a tiered scale — at high usage the rate can reach up to 5000 VND per kWh. To cut costs, run the AC in eco mode at 26-27°C combined with a fan, which roughly halves consumption compared to running it at 21-24°C normally.
What the community said
High electricity bills from AC use are normal, especially with an old, low-efficiency unit that draws much more power.

To cut the electricity bill roughly in half, set the AC to eco mode at 26-27°C and add a regular fan for airflow — the perceived temperature stays around 24°C, but power usage is much lower than running it normally at 21-24°C.

Electricity rates in Vietnam increase with higher consumption — at heavy usage the price per kWh can reach up to 5000 VND, which explains the large bills.
