High DEWA bill in Dubai: is it your AC?
A bill much higher than the same month last year. Air conditioning is often the reason, though not always. We check first, and we do not promise a percentage before looking.
What we measure here: temperature °C, air speed at the outlet m/s
Where we look first
- Dirty filters and coils
- Cold air leaking into the ceiling void
- Thermostat in the sun or near heat
To speed things up, send us
- A photo of this bill and the same month last year
- How many AC units you have
- When the bill went up
First, read the bill
Compare it with the same month last year rather than last month: the difference between May and July is mostly the weather. Compare the consumption printed on the bill, not the dirhams: kWh for electricity, and the water reading separately. The amount can rise with no extra use, because the fuel surcharge moves with fuel costs and the bill also carries the housing fee and sewerage. The electricity tariff also rises in steps, so a small rise in use can add more than you expect.
Also check whether a separate cooling provider bills you. If your building is on district cooling, the chilled water is normally charged separately from your DEWA electricity, so your AC settings mostly affect that charge. The fan coil's fan usually stays on your own electricity supply, so a fan running around the clock can still show on DEWA, though it draws far less than a compressor.
How the AC adds to it
- dirty filters and coils, so the system works longer for the same cooling
- a unit that never reaches the set temperature and never rests
- cold air leaking from ducts into the ceiling void, so you pay to cool the space above your ceiling
- a thermostat in direct sun or near a heat source
- a very low set temperature, or cooling rooms nobody is in
What we do
We measure how the system really runs: temperatures, airflow and running time. We fix what is wasting energy and leave you the same readings before and after. Then the next bills will show the rest.
What may be part of the fix here
Only if the readings call for it. Often nothing new is needed.
What we will not do
We will not quote you a percentage in advance. Sites that promise a fixed saving have not seen your home. It may also turn out that your AC is fine and the rise comes from a water heater, a leak or a change in the household. If so, we will say that, and we will not sell you work that does not help.
How we solve it
The same four steps, for a one-bedroom apartment or a warehouse.

You get: the readings.

You get: an itemised estimate. You decide.

Fix it
First clean, adjust, repair. New equipment last.

You keep: the sheet, before and after.
You see the result in numbers
Before the work and after it we take the same readings in the same places, and note the time and the weather outside. You keep the sheet, so you can see what changed without taking anyone’s word for it.

Tell us what is wrong
Leave your number and a few words about the problem. We will call back the same working day and arrange a visit to take measurements.
- You leave your number
- We call back the same working day
- We measure, then you decide
- In Dubai the first visit with measurements is free.
- We measure before we propose anything.
- If cleaning or a repair solves it, that is what the estimate will say.
- You keep the sheet with the readings before and after.
