DEWA Cost: Portable AC vs Fan in UAE Homes
Fans move air. Portable ACs remove heat. In UAE summer bedrooms you often need the AC. Fans win on the DEWA bill and as a partner to raise the AC set point.
Exact cost depends on your slab, fuel surcharge and how long the compressor runs. Use the figures below as order-of-magnitude planning, then check your own DEWA tariff.

Quick answer
A 1 ton portable AC draws around 1 kW. A tower fan draws tens of watts. Use each where it actually helps.
Quick comparison
| Device | Typical draw | Ballpark per 8 night hours |
|---|---|---|
| Portable AC 1 ton | About 1000 to 1300 W while cooling | Roughly a few AED per night at lower slabs |
| Tower fan | About 20 to 50 W | Cents per night |
| Desk fan | Under 20 W | Cents per night |

The picks
Also great
Xiaomi Smart Tower Fan 2
Quiet tower fan to spread AC air and let you raise the thermostat a degree or two, which usually saves more than the fan costs to run.
Budget pick
Oraimo 40 inch Silent Tower Fan
Budget fan for a second room. Low running cost. Not a substitute for AC in peak summer heat.
How to estimate your cost
Find watts on the appliance label. kWh for a night is roughly watts divided by 1000, times hours the compressor or motor actually runs. Multiply by the rate on your DEWA bill for your slab, plus fuel surcharge and VAT. Portable AC compressors cycle, so they do not draw max watts every minute.
When the fan is enough
Mild months, shaded rooms, and daytime desks where AC already holds 25 C. If the room is 32 C with weak AC, a fan alone will not fix sleep.
Rental tip
A fan needs no landlord approval. A portable AC needs a vent path. Start with blackout curtains and a fan, then add a portable AC only for the room that still fails.
FAQ
How much does a portable AC add to DEWA?
Often tens of AED per week if used nightly in summer, depending on slab and hours. Check your bill after a week of use.
Is a fan 10 times cheaper?
On watts, often ten to twenty times cheaper while running. Comfort is not equal.
Should I run both?
Yes in hot rooms. AC cools, fan mixes air and helps you set AC higher.
Do chiller buildings still see DEWA cost?
Yes for plug-in portable ACs and fans. Central chilled water is billed separately in many towers.
