AC not cooling in Dubai? Find the cause first
It runs and the air is barely cool, or one room stays warm. Before anyone adds gas or sells a new unit, it is worth knowing what is actually wrong.
What we measure here: temperature °C, air speed at the outlet m/s
Where we look first
- Blocked filter or dirty coil
- Thermostat reads wrong or sits in the wrong place
- A duct that has come apart above the ceiling
- The valve, or the building’s chilled water
To speed things up, send us
- A photo or short video of the problem
- A photo of the label on the unit
- When it started and what has changed
What it usually is
Most cases come down to air not moving or heat not leaving:
- a blocked filter or a dirty indoor coil, the most common and cheapest cause
- an outdoor unit choked with sand and dust, or one placed where it breathes its own hot air
- a thermostat that reads wrong or sits in the wrong place
- a duct that has come apart or lost its insulation above the ceiling
- a refrigerant leak or a failing compressor
An AC gas refill without finding the leak only delays the same problem. If someone offers that as the whole job, ask where the gas went.
Apartment on central or district cooling?
In many Dubai buildings you have no compressor of your own: a fan coil unit (FCU) in your ceiling takes chilled water from the building. Then the fault may be yours (filter, coil, valve, thermostat) or the building's supply. We measure and tell you which, and if it is the building's, you will know exactly what to report to management.
What we do
We measure the air temperature in and out, the airflow and the system pressures where there is a compressor. We repair what failed and measure again. If a repair no longer makes sense for the age and condition of the unit, we show you the comparison and you decide. If a unit really is past repair, the replacement can be a wall, floor-standing, window or portable unit, whichever suits the room.
What may be part of the fix here
Only if the readings call for it. Often nothing new is needed.
What this will not fix
Sometimes the unit is fine and the room simply gains too much heat, through large windows or a sun-facing wall. A repair will not change that, and we will tell you so.
How we solve it
The same four steps, for a one-bedroom apartment or a warehouse.
-
MeasureBefore
You get: the readings.

Find the cause
You get: an itemised estimate. You decide.
-
Fix it
First clean, adjust, repair. New equipment last.

Measure againAfter
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.
