Most Dubai Residents Are Paying Up to 20% More on Electricity (Without Knowing Why)
New findings from Octopus home maintenance technicians reveal the AC habit costing UAE residents more money every summer and the simple fix that costs nothing.
More Power Consumed
Switching AC on/off uses up to 50% more electricity vs. leaving it on 24° auto
Optimal Setting
24°C auto mode running continuously is the most energy-efficient setting for Dubai’s climate
Shorten Unit Lifespan
Repeated compressor restarts accelerate mechanical wear, reducing the unit’s working life
The Finding
The Habit Costing Dubai Residents More Every Summer
Every summer, Dubai residents switch their AC off to save money on their electricity bills. According to field data from Octopus technicians across hundreds of UAE service calls, this habit increases power consumption by 10–20% compared to leaving the unit running continuously on 24°C auto mode.
The reason is mechanical: every time an AC unit restarts from a warm room, the compressor must work significantly harder to bring the temperature back down to the desired level. That surge in effort consumes more electricity than if the unit had simply been maintaining a steady temperature throughout the day.
“Every time an AC restarts from a warm room, the compressor has to work significantly harder to bring the temperature back down. Over a summer, that repeated strain adds up not just on your electricity bill, but on the unit itself. The units we see that are constantly switched on and off wear down faster than those left running on a steady 24°. Most residents are shocked when we tell them.”

Key Facts
What the Data Shows
- 10-20% more power is consumed when switching an AC on and off compared to continuous operation at 24°C auto.
- 24°C on auto mode running continuously is the optimal setting. The unit scales to low-power maintenance mode once the room is cooled.
- Accelerated mechanical wear on the compressor results from repeated high-load restarts shortening the unit’s working lifespan.
- Based on field observations by Octopus technicians across Dubai residential service calls in 2024–2025.
The Science
Why Switching Off Costs More
An air conditioning unit on auto mode at 24°C does not run at full power continuously. Once the room reaches the target temperature, the unit scales back to a low-power maintenance mode using minimal electricity to hold the temperature steady.
When a resident switches the unit off, the room gradually warms back up. When they switch it back on, the unit must run at full compressor capacity until the room is cooled again, a process that consumes significantly more energy than simply maintaining the temperature would have.
In Dubai, where temperatures regularly exceed 45°C and residents spend the majority of the day indoors during summer, the cumulative cost of this on/off cycle across a full season is substantial.
Recommendations
What Should You Do
1
Leave it on at 24°C auto
Set to 24°C auto mode and leave it running continuously. This is the most energy-efficient approach for Dubai’s climate and puts the least strain on the compressor.
2
Don’t set below 20°C
Lower temperatures force the compressor to work harder, not smarter, increasing energy consumption without meaningfully improving comfort.
3
Clean filters every 3 months
A clogged filter forces the unit to work harder to push air through, increasing energy consumption and reducing air quality.
4
Service the unit before summer
A well-maintained unit runs more efficiently and is far less likely to break down during peak demand months in June–August.
Methodology & Data Notes
The findings in this report are based on field observations by Octopus home maintenance technicians collected across residential service calls in Dubai. The 10-20% power consumption figure reflects the difference in energy load between an AC unit restarting from a warm room versus maintaining a steady temperature, as observed and recorded during routine maintenance visits.
