AC Drain Tray Cleaning in Abu Dhabi
An AC removes humidity from the air, and that water collects in a drain tray before leaving through a pipe. ALHUD Technical LLC provides AC drain tray cleaning for villas, apartments, offices and shops in Abu Dhabi, so water leaves the unit as it should and not onto your wall or ceiling.
Humid Abu Dhabi summers put a lot of water through the system. Dirt and slime in the tray or pipe block it surprisingly quickly.
Signs of a Blocked Drain Tray
- Water dripping from the indoor unit or the wall below it
- Water stains or damp patches on the ceiling or wall
- A musty or sour smell when the AC runs
- Water overflowing around the vent
- Unit switching off with a water or drain error on some models
If the air is not cold either, see our AC repair page.
Why Drain Trays Block
Dust, pollen and slime build up in a damp tray. Dirty filters let more dirt reach the coil, which then washes into the tray. Poorly sloped pipes, kinks and bent outlets also hold water. Regular cleaning and clean filters keep the system flowing.
How We Clean the Tray and Pipe
We switch off the unit, open the covers, remove dirt and slime from the tray and clear the drain pipe by flushing or suction. We check that the pipe slopes correctly, test the flow with water and treat mould and smell. We then re-check the unit while it runs.
Split, Ducted and Cassette Units
Split units have a small tray and pipe, so blockages show quickly. Ducted and cassette units may use pumps and longer pipes, which need extra checks. Our split AC repair team handles wider faults, including leaks that are not drain-related.
Leak Caused by Something Else?
Not every leak is a blocked drain. A frozen coil, low refrigerant or a damaged tray can also cause dripping. We check these causes if cleaning does not solve it. A frozen coil melting is a common false alarm, so we test the airflow too.
How an AC Drain Tray Cleaning Works
- Inspect. We check the unit, the tray and the signs of leaking.
- Quote. We explain the work and give a price before starting.
- Open and clean. We open the unit and remove dirt and slime from the tray.
- Clear the pipe. We flush or suction the drain pipe and check the slope.
- Test. We run the unit, test water flow and confirm there is no drip.
Filters and drains are often cleaned together, so see our AC filter cleaning page.
Keeping the Drain Clear
Clean filters every few weeks in heavy use, book a yearly AC maintenance service and run the AC regularly so the drain does not sit stagnant. Do not pour harsh chemicals into the tray, as they can damage parts.
