Al Karama Technical LLC repairs central and ducted air conditioning in villas, apartments, offices and shops anywhere in Dubai, usually starting the same day.

Al Karama Technical LLC repairs central air conditioning across Dubai, including ducted split systems, package units, VRF systems and chilled-water fan coil units connected to a building chiller or district cooling. A technician usually arrives the same day, finds where in the system the fault is, explains it and gives you a fixed quote. Most repairs, such as drain blockages, fan motors, thermostats, capacitors, valves and gas leaks, are finished on that visit.

One team for the whole system, from the outdoor unit or chilled water valve to the last grille.
Outdoor condensing units, ceiling fan coils, capacitors, contactors and blowers.
Fan coil units, thermostats, valve actuators and drains in towers.
Error codes, sensors, boards and indoor units on multi-split systems.
Rooftop units for villas, shops and warehouses.
Blocked condensate drains, overflowing trays and sweating ducts.
Crushed or disconnected ducts, stuck dampers and leaking joints.
A central AC has more places to go wrong than a wall unit: an outdoor condensing unit or a building chiller, an indoor unit hidden in the false ceiling, a network of ducts, dampers and grilles, and a thermostat in each zone. When you search for central AC repair near me, you need a technician who can test all of them, not just top up the gas.
We work on villas in communities like Arabian Ranches, The Springs and Mirdif, on apartments and offices running on chilled water, and on shops and warehouses with rooftop package units. Dirty or leaking ducts are often part of the problem, so we also offer AC duct cleaning in Dubai.
Central AC repair sits alongside our wider home appliances repair Dubai service, so one booking can cover other appliances too.
The symptom usually tells us which part of the system to test first. These are the faults we see most in Dubai homes and offices:
| Problem | Most likely cause | How we fix it |
|---|---|---|
| Whole house warm | Outdoor unit stopped (capacitor, contactor, gas leak or compressor), or no chilled water from the building | Test the outdoor unit, or check the chilled water supply and valves |
| One room not cooling | Closed or stuck damper, disconnected or crushed flexible duct, blocked grille, zone thermostat fault | Inspect the ducts above the ceiling, reconnect or repair, adjust the dampers |
| Water dripping from the ceiling | Blocked condensate drain or overflowing tray, sweating ducts with poor insulation | Clear the drain line, clean the tray, repair the insulation |
| Weak airflow from the vents | Dirty return filter or coil, slow blower motor, leaking ducts | Clean, replace the blower motor or capacitor, seal the leaks |
| Thermostat blank or not responding | Failed thermostat, wiring fault or control board problem | Test the wiring and controller, replace the thermostat |
| Runs all day but never cools enough | Low gas, dirty coils, an undersized system or heavy duct losses | Find the cause, repair and rebalance the system |
| Noise from the ceiling | Worn blower bearings, loose panels or a fan rubbing its housing | Replace the motor or bearings, secure the unit |
| Musty smell from the vents | Mould in the drain tray, coil or ducts | Clean and sanitise the unit and drain, clean the ducts |
Dubai buildings use four main types of central air conditioning, and each is repaired differently. Knowing yours helps us send the right technician and parts:
| System | Where you'll find it in Dubai | What we repair |
|---|---|---|
| Ducted split (DX) | Villas and townhouses: an outdoor unit plus a ceiling unit for each zone | The whole system, indoor and outdoor |
| Package unit | Rooftops of villas, shops and warehouses, with everything in one outdoor box | The whole unit and its ducts |
| VRF or VRV | Larger villas, offices and clinics, with one outdoor unit serving many indoor units | Error codes, sensors, boards and indoor units |
| Chilled water FCU | Apartments and offices on district cooling or a building chiller | The fan coil unit, thermostat, valve and drain; the chilled water supply is the building's job |
Living in a tower with chilled water? Your flat has fan coil units in the ceiling, but the cooling itself comes from the building’s chiller plant or a district cooling provider. If every room is warm, check with building management first. If one room is warm while the rest are fine, the problem is usually your fan coil unit, thermostat or valve actuator, and that’s what we fix.
For the building chillers themselves, see our chiller repair in Dubai service.
If you see water coming through the ceiling, switch the system off and put a bucket underneath. A blocked drain can damage a gypsum ceiling quickly.
Many ducted systems in villas have a separate thermostat for each zone. If only one zone has stopped, check that thermostat’s display and settings before you call.
Tell us the system type, the symptoms and which rooms are affected.
We book the closest central AC technician, often the same day.
Outdoor unit, ceiling unit, ducts, drains and controls are checked.
You approve the price, we repair and check the air at the vents.

The cost of central AC repair in Dubai depends on the system type, where the fault is and how easy it is to reach. A blocked drain costs far less than a compressor or a duct replacement. We diagnose first and give you a fixed quote before any work starts.
| Type of job | Typical cost level | Typical time on site |
|---|---|---|
| Drain line and tray clearing | Lower | 1 to 2 hours |
| Thermostat replacement | Lower to medium | 30 to 60 minutes |
| Capacitor or contactor | Lower to medium | 30 to 60 minutes |
| Blower motor or FCU valve actuator | Medium | 1 to 3 hours |
| Duct repair or reconnection | Medium | 2 to 4 hours, depending on access |
| Leak repair and gas recharge | Medium to higher | Half a day |
| Compressor replacement | Highest | A full day or more |

Most central AC repairs cost a small fraction of a new unit.
Rebalancing ducts and dampers fixes the warm room at the end of the run.
Clearing drains early stops water stains and collapsed gypsum boards.
Common parts travel in the van, so most jobs are finished within hours of your call.
We fix what made the part fail, so the same fault doesn't come back next month.
An itemised invoice helps with landlord claims, resale and warranty questions.
Most numbers for central AC repair near me promise the same thing. This is what to look for in any company, and what we do:

| Whole-system diagnosis | Outdoor unit, ceiling unit, ducts, drains and controls are all checked, not just the gas. |
| Testing before replacing parts | We test the cheaper parts first and only recommend a board or major part when the tests point to it. |
| The right parts | Original or manufacturer-approved parts, with the part type written on the invoice. |
| Proof of the fault | We show you the old part and let you keep it. |
| A proper invoice | Company name, trade licence, model and serial number, parts fitted and warranty period. |
| Fast, local response | Technicians working across Dubai every day from our Al Karama base, with same-day visits for most bookings. |
Central systems run for long hours in Dubai, and most breakdowns start with dust and blocked drains. A maintenance plan prevents most summer failures:
ENERGY STAR estimates that about 20 to 30 percent of the air moving through a typical duct system is lost through leaks and poor connections, which is why rooms at the end of a long duct run often feel warm.
Villa owners often add an appliance check to their AC service through our home appliance repair team.
Most central AC faults are repairable: drains, motors, thermostats, capacitors, valves and duct leaks. Replacement is worth discussing when an older system needs a new compressor, still uses R22 gas, which is being phased out, or keeps losing gas from corroded coils.
Often only part of the system needs replacing. A worn outdoor unit can sometimes be replaced while keeping the ducts, and leaking ducts can be repaired without changing the units. We’ll give you clear options with prices so you can decide.
VRF systems need brand-specific diagnostic tools and error code knowledge. If your VRF controller shows a fault code, send us a photo of the display and the outdoor unit label. It often tells us which sensor, board or indoor unit is at fault before we arrive.
Villa owners often book other appliances while we’re there. If your fridge struggles in a hot kitchen, our fridge repair service can fix it on the same trip.
We also handle washing machine repair for laundry rooms.

The most common causes are a blocked filter, a failed capacitor or contactor in the outdoor unit, low gas from a leak, a slow blower motor or, on chilled water, a supply or valve problem. A technician needs to test the system to find which.
Usually a closed or stuck damper, a disconnected or crushed flexible duct above the ceiling, a blocked grille or a faulty zone thermostat. These are repairable without changing the system.
A blocked condensate drain or an overflowing drain tray is the usual cause. Sweating ducts with damaged insulation can also drip. Switch the AC off and call us before the ceiling is damaged.
Yes. We repair fan coil units, thermostats, valve actuators, fan motors and drains in flats and offices on district cooling or a building chiller. The chilled water supply itself is the building’s responsibility.
