Best AC Modes to Save Electricity
Using the right AC mode can reduce unnecessary electricity usage and keep your room comfortable. Different modes are designed for different situations, so choosing the correct one helps your AC run efficiently without overloading the compressor.
| Mode | When to Use | Power Impact | Tip |
| Eco Mode | Mild heat | Reduces compressor load | Use during relaxed hours |
| Dry Mode | Humid weather | Uses less power | Ideal for monsoon |
| Sleep Mode | Night | Gradual temp increase | Saves energy while sleeping |
How to Optimise Your Room Settings for Maximum Power Savings
Your room setup plays a big role in how much electricity your AC uses. Small changes to sunlight control, airflow, and ideal AC temperature settings can help your Onida AC cool faster and reduce the compressor’s load. This means better cooling with lower electricity use.
| Room Condition | Recommended Setting | Tip |
| Sunlight exposure | 24°C Cool Mode | Use curtains |
| Open spaces | Auto Fan | Keep doors closed |
| Top-floor rooms | 25°C + Fan | Circulate cool air |
Common Mistakes That Increase Electricity Bills
Wrong AC settings can quickly increase your electricity bill without giving better cooling. Many people use extreme settings, thinking it will cool faster, but it only puts extra load on the compressor and wastes electricity every day.
Avoid these habits:
- Setting the temperature to 18°C: Lower temperature doesn’t cool faster; it overworks the compressor, increasing energy use and unnecessary electricity consumption.
- Running fan at max speed all day: Constant high fan speed wastes energy even after cooling, reducing efficiency and increasing overall power consumption unnecessarily.
- Leaving doors/windows slightly open: Even small openings let cool air escape, forcing the AC to run longer and consume more electricity to maintain the temperature.
Ideal setting: 24°C for best efficiency
These small mistakes can significantly increase your monthly electricity usage. To learn more practical ways to save energy, read our guide on how to reduce AC bill.
