Best AC Temperature in Dubai to Cut Your DEWA Bill
Quick answer: For most Dubai homes the sweet spot is around 24 to 26 degrees. It keeps you comfortable while using far less power than the 18 to 20 many people set out of habit. Every degree lower makes the compressor work harder, so nudging the thermostat up a couple of degrees is one of the easiest ways to cut a summer bill.
Why 24 to 26 is the sweet spot
Cooling is the biggest slice of a Dubai electricity bill, and the AC does not cool a room faster by being set to 18. It simply runs longer to reach that colder target and then keeps working to hold it. Setting a sensible temperature and letting the unit maintain it steadily is more comfortable and much cheaper than chasing an extreme number.
How much each degree costs
As a rule of thumb, every degree you lower the thermostat adds meaningfully to cooling energy, which is why DEWA promotes moderate settings as a headline energy-saving habit.
| Setting | Comfort | Effect on bill |
|---|---|---|
| 18 to 20 degrees | Very cold, often too cold at night | Highest running cost |
| 22 to 23 degrees | Cool and comfortable | Moderate |
| 24 to 26 degrees | Comfortable for most rooms | Lowest sensible cost |
Thermostat habits that save
- Set one steady temperature rather than swinging it up and down
- Raise it a few degrees when you leave, do not switch off for short trips
- Use fans so a slightly warmer setting still feels cool
- Close curtains against direct sun during the day
- Keep doors closed so you are not cooling empty space
Myths about AC settings
Setting the AC to its lowest number does not cool the room quicker, it only makes it overshoot and run longer. Leaving the AC on a moderate setting all day can also beat switching it off and on if you are out for just a couple of hours, because pulling a hot room back down from scratch uses a burst of energy.
When a high bill is the AC itself
If you already set a sensible temperature and the bill is still high, the unit may be the problem. Dirty coils, a clogged filter, low gas or an oversized unit all waste power. A serviced, efficient AC holds your chosen temperature with far less effort, so booking an AC service often saves more than any thermostat tweak.
Frequently asked questions
What is the best AC temperature for Dubai?
Around 24 to 26 degrees suits most homes. It is comfortable and uses far less power than the 18 to 20 many people set out of habit.
Does setting the AC lower cool the room faster?
No. The room cools at the same rate. A lower setting just makes the unit run longer to reach and hold a colder target, using more power.
How much can raising the temperature save?
Each degree higher cuts cooling energy noticeably. Moving from 20 to 24 degrees can make a clear difference on a summer bill over a full month.
Should I turn the AC off when I leave?
For short trips, raise the temperature rather than switching off, because cooling a hot room from scratch uses a burst of energy. For long absences, switch it off.
Why is my DEWA bill high even at a sensible temperature?
The unit may be inefficient. Dirty coils, a clogged filter, low gas or an oversized system all waste power regardless of the thermostat setting.
Do fans help lower the AC bill?
Yes. Fans move air so a slightly warmer AC setting still feels cool, letting you raise the thermostat a degree or two without losing comfort.
Is it bad to run the AC all day?
Running it steadily at a moderate setting is fine and can be cheaper than repeatedly cooling a hot room from scratch if you are only out briefly.
