In Dubai, air conditioning is not a luxury. It is an essential part of keeping your home comfortable during the hottest months. But if your Dubai Electricity and Water Authority (DEWA) bill climbs every summer, your AC is probably one of the biggest reasons.
The way you set and maintain your AC can make a real difference to how much electricity it uses. This guide looks at the best AC temperature in Dubai to reduce DEWA charges, how thermostat settings affect your bill, and what you can do to keep your home cool without wasting energy.
Key Takeaways
- DEWA recommends setting your AC thermostat to 24 degrees Celsius or higher.
- Raising the setting to 25 or 26 degrees Celsius, when comfortable, can reduce cooling load further.
- Clean AC filters regularly so airflow is not blocked.
- If your DEWA bill rises despite similar usage, your AC may need a professional inspection.

What Temperature Should You Set Your AC to in Dubai?
DEWA recommends setting your AC thermostat to 24 degrees Celsius or higher. For many homes, the 24-degree AC setting in Dubai is a practical balance: cool enough to stay comfortable, but not so low that your system has to work harder than necessary.
In peak summer, it can be tempting to drop the temperature to 18 or 20 degrees Celsius for quicker relief. However, a lower AC thermostat setting during those months in a desert city like Dubai usually means longer run times, higher electricity use, and higher monthly charges.
Best AC Settings for Day, Night, and When Leaving Home
Want to learn how to reduce your AC electricity bill in Dubai beyond keeping it at 24 degrees Celsius? A realistic approach is to adjust your thermostat around your routine.
During the day, start at 24 degrees Celsius. If the room still feels comfortable, try increasing the temperature to 25 or 26 degrees Celsius, especially when you’re sitting still, using a fan, or keeping the curtains closed.
At night, a steady setting around 24 to 25 degrees Celsius should suffice. Once the bedroom has cooled, a slightly higher setting may still feel comfortable because you are less active and using lighter bedding. Good airflow can also help the room feel cooler without forcing the AC to run harder.
When leaving home for several hours, raise the thermostat rather than setting it too low. For extended trips, consider leaving one AC unit running at 26–27°C so it operates only when needed. In villas, an upstairs unit is often the most effective choice, as cool air naturally falls through the property, helping to control heat and humidity while you’re away.

Does a Dirty AC Filter Increase DEWA Bills?
Yes. A dirty or clogged AC filter can increase your DEWA bill because it restricts airflow and reduces cooling efficiency. Clogged or dirty AC filters can block normal airflow and significantly reduce system efficiency, so the AC may run longer to reach the same temperature.
Regular professional AC maintenance can help keep filters, coils, and other components clean and operating efficiently. Consider booking a service if you notice weak airflow, musty smells, dust around vents, recurring allergy-like irritation, or signs that your system is not cooling as effectively as it should.
When Does High Energy Use Mean Your AC Needs an Inspection?
High DEWA usage does not always mean your AC is faulty. During Dubai’s hotter months, AC systems naturally work harder to maintain the same indoor temperature, which can lead to higher energy consumption even when your usage habits have not changed.
However, if your bill increases significantly despite similar usage patterns, or your AC runs constantly while rooms remain warm, it may be time for a professional inspection.
Other warning signs include:
- Weak airflow
- Rooms cooling unevenly
- Unusual noises or smells
- Water leaks
- Condensation around the unit
Never open electrical panels or AC components yourself. If adjusting your thermostat does not improve performance, book a professional AC inspection to identify any underlying issues and ensure your system is operating safely and efficiently.
Frequently Asked Questions
Does setting the AC to 24 degrees Celsius reduce electricity use?
Yes. Setting your AC to 24 degrees Celsius or higher can help reduce electricity use because the system does not have to work as hard to cool the room. Every one-degree increase in set temperature can save up to 5 per cent on AC consumption.
Should I use Auto mode or Cool mode?
Use Cool mode when you need the AC to bring the room down to your chosen temperature. Auto mode can then help manage the fan once the room reaches that setting, depending on your AC model. If comfort or airflow feels inconsistent, the unit may need checking.
Do blackout curtains help reduce AC consumption?
Yes. Blackout curtains, shades, awnings, and reflective materials can help reduce heat entering through windows, so your AC has less work to do. These measures can improve cooling efficiency, especially in rooms exposed to direct sunlight during the day.
Stay Cool and Save Energy
The best AC setting in Dubai focuses on balance. Start with DEWA’s recommendation, then adjust based on comfort, room use, and time of day. Keep filters clean, block direct sunlight, and avoid very low settings. If your AC still runs constantly or the airflow feels weak, book a professional AC service in Dubai.
