Dubai · AC coil cleaning

When filter cleaning no longer brings the cold air back, the dirt is on the coil. A chemical wash strips the dust cake and mould off the indoor coil and blower wheel of your split or concealed ducted unit - AED 211.60 for one split unit, travel included.

Coil cleaning prices

Pick your unit type and how many units need cleaning. Ducted units cost more because the technician works through the ceiling access panel and cleans the plenum as well as the coil. Ducted from AED 338.56.

How AC Coil Cleaning Is Done

For units that smell, sweat or blow weak air after a routine clean - the coil is treated, not just brushed.

  • 1. Area protected

    Furniture and floors under the unit are covered and a collection bag is fitted under the coil.

  • 2. Panels and filters removed

    Front panel, filters and covers come off so the coil and blower are fully exposed.

  • 3. Coil cleaner applied

    A coil cleaning solution is applied to the evaporator fins and left to break down the bonded dirt and mould.

  • 4. Pressure rinse

    The coil and blower wheel are rinsed with a low-pressure jet into the collection bag.

  • 5. Drain line cleared

    The drain tray and condensate line are flushed so the rinse water and sludge leave the unit.

  • 6. Reassembled and tested

    The unit is reassembled and run, and the supply-air temperature is checked against the reading before cleaning.

  • 7. Outdoor unit and gas checked

    The condenser and gas pressure are checked; any further work is quoted before it is done.

Signs your coil needs a chemical wash

  • A damp, musty smell for the first few minutes after you switch the AC on.
  • Black specks or grey fluff around the supply diffusers or on the louvres - that is mould and dust blown out of the unit.
  • Air comes out cool but weak, even with a clean filter.
  • The unit runs non-stop in the evening and the room still sits at 26°C or more.
  • Water drips from the ceiling grille or the indoor unit after a long run.
  • Your DEWA bill climbed this summer without any change in how you use the AC.

Why coils in Dubai clog faster

An AC in Dubai works far harder than one in a mild climate. From May to October most units run day and night, and even in the cooler months they rarely get a long rest. Every hour of running pulls room air - and whatever is in it - across the indoor coil.

Fine desert dust is the main problem. During shamal winds and dust storms it gets into apartments through balcony doors, window seals and the fresh-air intake, and a lot of it passes straight through standard filters. On the cold, wet coil it sticks, mixes with condensate and bakes into a grey layer that blocks airflow. Mould grows on that layer because the coil is wet for most of the day.

Concealed ducted units suffer most. They sit above the false ceiling, so nobody sees them, and the return-air filter behind the grille is the only part most tenants ever touch. By the time the smell starts, the coil has usually been dirty for a year or more.

What the chemical wash includes

  • Isolate the unit and protect the floor and furniture below it.
  • Remove and wash the filter and return-air grille.
  • Apply coil cleaner to both faces of the indoor coil and leave it to dissolve the dust and biofilm.
  • Rinse the coil with low-pressure water and catch the run-off.
  • Clean the blower wheel - the curved fan blades where mould builds up and causes the smell.
  • Flush the drain tray and condensate line so the water you rinse out actually leaves the unit.
  • Check airflow and supply-air temperature after reassembly, and show you the before-and-after.

Before the technician arrives

Building access

Many Dubai towers need a contractor gate pass or work permit from building management. Tell us when you book and we send the technician and company details for the permit.

Ducted unit access

For a concealed unit we need the ceiling access panel. If it is painted shut or blocked by built-in wardrobes, let us know - the technician brings tools to open it cleanly.

District-cooled buildings

If your building is on district cooling, your apartment unit is a chilled-water fan coil. It still needs its coil and drain cleaned, but there is no refrigerant gas to refill.

How often to chemical wash in Dubai

For most apartments, once a year is enough if the filters are cleaned every month or two and the unit gets a routine clean every three to four months. The best time is March or April, before the heat - your unit then starts summer with a clean coil instead of fighting dust from the winter.

Homes near construction sites, ground-floor apartments and villas with pets, or anyone with allergies or asthma, usually need a coil wash every six months.

Questions people ask

With StringsSG, a chemical wash costs AED 211.60 for one split unit and AED 338.56 for one concealed ducted unit. The price per unit drops as you add units - three split units cost AED 566.03 in total. Travel is included.
No. Coil cleaning cleans the indoor unit itself - the coil, blower wheel and drain tray. Duct cleaning cleans the ducts that carry air from a ducted unit to the rooms. If the smell or weak airflow comes from the unit, coil cleaning fixes it; dusty ducts are a separate, less frequent job.
About 60 to 90 minutes for a split unit and two to three hours for a concealed ducted unit, depending on how dirty it is and how easy the access panel is to work through.
The coil cleaner is rinsed off before the unit is reassembled, and the run-off is caught and taken away. Keep pets out of the room while the technician works and air the room for a few minutes afterwards.
Tenancy contracts in Dubai usually split AC upkeep: routine cleaning is often the tenant's job, while major repairs fall on the landlord. Check your contract and see our guide on who pays for AC maintenance in Dubai.
Yes. The fan coil in a district-cooled apartment gets the same coil, blower and drain clean. We do not touch the building's chilled-water supply - that belongs to the building and the cooling provider.
A normal cleaning brushes the surface. Coil cleaning applies a cleaning solution to the fins and rinses it through, removing bonded dirt and mould that brushing leaves behind.
