Running Costs

## Cutting Your TNB Bill

-   Set the temperature to around 24 to 25°C instead of 18°C.
-   Keep doors and windows closed while the aircon runs.
-   Rinse the filters every few weeks and service the unit regularly.
-   For rooms used every night, an inverter unit usually costs less to run.
