FAHU and FCU Servicing in Dubai
The fresh air unit is the one piece of plant nobody has ever opened.
Fresh air handling units, fan coil units, drain pans and recovery wheels, serviced properly.

The part of the system nobody opens
A blower wheel silts up blade by blade until the unit is moving a fraction of the air it was designed to. Nothing sounds wrong. The rooms simply stop cooling.
- Blower wheel removed and cleaned off the shaft
- Coil fins combed and washed, not just rinsed
- Drain pan and line cleared and treated

Airflow restored, not just surfaces cleaned
A clean coil with a dirty duct behind it reloads within weeks. We look at the whole path before quoting on any one part of it.
- Static pressure checked before and after
- Duct condition assessed at the same visit
- Findings written down, not described verbally

Cooling you can feel in the bill
A restricted coil makes the compressor run longer for the same room temperature. Cleaning it is the cheapest efficiency work available on a villa.
- Delta T measured on completion
- Refrigerant pressures checked
- Report you can hold the next contractor to
Before anything is quoted
We look at the property before we put a number on it
A price list cannot see your marble, your ducts, or the wall the afternoon sun hits. So we come and look. A senior member of the team surveys the property, and you receive a written quotation the same day, itemised, with what is included and what is not.
No obligation. If we are not the right company for the job we will say so, and tell you who is.
- 01The survey
We look at the property, not a price list. Usually the same day you ask.
- 02The written quote
Fixed, itemised, and sent the same day. What is included, and what is not.
- 03The work
A named supervisor and a crew you will see again. Our own equipment and materials.
- 04The walkthrough
We walk the property with you before the team leaves. Anything not right is dealt with then.
About this service
What is fahu & fcu servicing and what does it include?
An FCU with a blocked drain pan does not stop working. It just starts growing things.
Most Dubai villas and apartments on central chilled water run fan coil units above the ceiling, and most FAHUs sit on a roof or in a plant room where nobody goes. Both are out of sight, which is precisely the problem. The FCU drain pan sits permanently wet, and when the drain line silts up the pan holds standing water, which is where the smell in the hallway comes from and eventually where the water stain on the ceiling comes from. The FAHU meanwhile is pulling outside air into the building through a filter that in this climate loads far faster than the schedule assumes.
We service both properly rather than swapping a filter and closing the hatch. FCU coils are cleaned rather than wiped, drain pans are flushed and the condensate line cleared and treated, and the pan is checked for corrosion, because a rusted pan is why the ceiling stain came back after the last visit. On FAHUs we clean coils, replace filters to the correct grade rather than whatever fits, inspect and clean the energy recovery wheel including its seals and belt, and check dampers and controls. Access panels get closed with their gaskets intact, which sounds obvious and frequently is not done.

View serviceFrequently asked questions
How much does FAHU and FCU servicing cost in Dubai?
There is no fixed rate card. Price follows the size and condition of the property, so a senior member of the team surveys it first and you get a written, itemised quotation the same day. The figure on that quotation is the figure you pay.
Who does FAHU and FCU servicing near me in Dubai?
MELLS covers ninety communities across Dubai and works in Abu Dhabi and Sharjah for commercial premises. Message +971 58 656 3001 on WhatsApp with your community and we will confirm availability.
What is the best FAHU and FCU servicing company in Dubai?
Judge any company on three things: whether the team is directly employed or subcontracted, whether the quote is fixed in writing before work starts, and whether a supervisor walks the property with you at the end. MELLS does all three as standard.
How quickly can you start FAHU and FCU servicing?
Survey usually the same day you ask, quotation the same day, and work scheduled within forty eight hours in most cases. Urgent call outs are handled the same day where the team is free.
Is FAHU and FCU servicing safe for children and pets?
Yes. Products are selected for occupied family homes as the default, re entry times are told to you before we leave, and anything stronger is only ever used with your agreement.
How do I get a quote from MELLS?
Message us on WhatsApp on +971 58 656 3001 or call the same number. A senior member of the team surveys the property and you receive a written itemised quotation the same day.
Which areas of the UAE does MELLS cover?
Ninety communities across Dubai for residential work, and Dubai, Abu Dhabi and Sharjah for commercial premises.
Why does the hallway smell musty?
Almost always a blocked FCU drain pan holding standing water above the ceiling. It is not a filter problem and changing the filter will not fix it.
What is the difference between an FCU and a split AC?
An FCU has no refrigerant of its own. It runs chilled water from a central plant through a coil, with a fan blowing across it, which is why the servicing is different work.
How often should FAHUs be serviced?
Twice a year in Dubai, minimum. Filters load much faster here than the manufacturer's generic schedule assumes because of the dust load.
Do I need the recovery wheel cleaned?
If you have one, yes. A dirty or stalled wheel quietly removes most of the efficiency benefit the unit was installed for.
Can you fix the ceiling stain too?
Yes. We fix the drain cause first, then patch and repaint, all under one contract rather than sending you to a second company.
Ready to book fahu & fcu servicing?
Quick response, trained technicians, and a price agreed before we start.
The difference
Why a cheap fAHU and FCU Servicing job is expensive
The gap is not the price. It is what is actually reached, and whether anyone can show you it was.
The low cost visit
- A price given over the phone, sight unseen
- A small crew, in and out inside a few hours
- Subcontracted labour you have never met before
- The hard to reach areas quietly skipped
- One product used on every surface in the property
- Booked again within weeks because nothing was resolved
The MELLS method
- A senior surveyor attends before any figure is given
- A crew sized to the property, with a named supervisor
- Directly employed, vetted, trained staff, nothing subcontracted
- A written checklist covering the areas nobody else reaches
- Products chosen per surface, stone treated as stone
- Photographs on completion and a walk through with you
