Same-day AC repair across Dubai · Since 2015
AC not cooling, blowing warm air, leaking water, tripping the power or making a loud noise? In Dubai’s heat that’s an emergency. Al Karama Technical LLC sends a trained AC technician to your home or business anywhere in the city, usually the same day. We find the real fault, give you a fixed price before any work starts, and fix most AC problems in one visit, backed by our workmanship warranty.
Al Karama Technical LLC repairs split, ducted, window, cassette, VRF and central air conditioners of every major brand across Dubai. A technician usually reaches you the same day. They test the gas pressure, electrics, fans, compressor and drainage, explain the fault, and give a fixed quote. Most repairs, such as capacitors, fan motors, blocked drains, thermostats and gas leak repair, take 1–2 hours. Larger jobs like compressor replacement are scheduled promptly.
Dubai summers regularly pass 45°C, and air conditioners run almost all year. Dust, sand, humidity and long running hours wear out capacitors, fan motors and compressors, and clog filters, coils and drain lines. When an AC fails, you need a technician quickly, not in three days.
Searching for AC repair near me? Since 2015, our AC technicians have worked across Dubai, from Karama, Bur Dubai and Deira to Dubai Marina, JVC and Arabian Ranches. Our vans carry the parts that fail most often: capacitors, contactors, fan motors, thermostats, sensors, drain pumps and refrigerant. That means most AC repairs are finished in one visit.
We never guess. We test, explain what’s wrong in plain language, and give you a fixed price before we start. If a repair isn’t worth it, we’ll tell you honestly.
These are the air conditioner faults we see most often in Dubai, what usually causes them, and how our technicians fix them.

An air conditioner doesn’t “use up” gas. If the refrigerant is low, there’s a leak. A quick top-up without fixing the leak means you’ll be calling again within weeks, and running an AC short of gas can damage the compressor.
Our AC gas refill process:
Older units using R22 are becoming expensive to recharge. For those, we’ll tell you honestly whether repair or replacement makes more sense.
Most ACs sold in Dubai today are inverter models. Instead of switching on and off, they vary compressor speed to hold the temperature, which saves energy but adds electronics that can fail: inverter boards, sensors and DC fan motors. Diagnosing an inverter AC takes more than a multimeter and a gas gauge.
Our technicians read the unit’s fault codes, test the inverter board outputs, compressor windings and sensors, and check communication between the indoor and outdoor units. Many “dead compressor” diagnoses from other companies turn out to be a board or sensor fault that costs far less to fix. Getting the diagnosis right the first time is where most of your savings come from.

We use genuine spare parts wherever they’re available, and we tell you before fitting any compatible alternative.
AC repair cost in Dubai depends on the fault, the AC type and brand, and whether parts or refrigerant are needed. A capacitor costs far less than a compressor or inverter board. That’s why our technician always diagnoses first and gives you a fixed quote before starting.
As a guide, here’s how long common AC repairs take:
| Repair | Typical time | Notes |
|---|---|---|
| Capacitor or contactor replacement | 30–60 minutes | The most common cause of 'outdoor unit not starting' |
| Drain line or drain pump repair | 45–90 minutes | Stops indoor unit water leaks |
| Fan motor replacement | 1–2 hours | Indoor or outdoor fan |
| Gas leak repair and refill | 2–3 hours | Leak search, repair, vacuum and recharge |
| PCB / inverter board repair | 1–3 hours | Board repair or replacement, depending on model |
| Compressor replacement | Half day | Includes vacuum, recharge and full test |
Commercial, VRF and central systems are quoted individually after inspection. If you decide not to go ahead after diagnosis, you only pay the visit charge.
A code on your AC display points our technician to the right part quickly. Here’s what some common codes usually mean. Codes vary by model, so send us a photo on WhatsApp and we’ll tell you what it points to before we arrive.
| Brand & code | What it usually means | What we do |
|---|---|---|
| Daikin U4 / UA | Communication error between indoor and outdoor units | Check wiring and connections, test PCBs |
| Daikin A5 / A6 | Indoor coil freeze protection or fan motor fault | Clean coil and filter, test indoor fan motor |
| LG CH05 / CH10 | Communication or indoor fan error | Test wiring and fan motor, repair board |
| Samsung E1 / E4 | Sensor fault or indoor coil freezing | Test thermistors, clean coil, check gas |
| Mitsubishi flashing lights | Protection or sensor fault (count the flashes) | Read the flash pattern, test the related part |
| Any brand: timer light blinking | General protection fault | Full electrical and pressure diagnosis |
Most AC breakdowns we see could have been prevented. Dust and sand clog filters and coils, drains block in the humidity, and units run flat out for months. Simple habits make a big difference:
Most AC faults are worth repairing, especially capacitors, fans, drains, sensors, boards and leak repairs. Replacement starts to make sense when:
We’ll give you both options with honest numbers.
When the AC fails in a restaurant, office or hotel, customers and staff notice within minutes. We give commercial callouts priority, repair VRF and central systems, and offer planned maintenance so problems are caught before peak season.
Fast room-unit repairs and planned maintenance to protect guest comfort.
Cassette, ducted and kitchen-area ACs kept running through service hours.
VRF and ducted systems repaired after hours to avoid disruption.

In Dubai, who pays for AC repair usually depends on your tenancy contract and the type of fault. Many contracts make the landlord responsible for major repairs, while the tenant covers routine maintenance and minor fixes. Check your contract, and speak to your landlord or management company before booking a major repair.
We make this easy for everyone involved. Our technician explains the fault in writing, photographs the damaged parts, and gives a clear itemised quote you can forward to your landlord or property manager for approval. For property managers and building owners, we offer planned maintenance across multiple units, with fast response for tenants and simple reporting.

Straight answers to the questions Dubai customers ask us most about AC repair.
It depends on the fault, AC type and brand. Capacitors, drains and fan motors cost much less than a compressor or inverter board. Our technician diagnoses first and gives you a fixed quote before any work starts.
Yes. Most calls are handled the same day anywhere in Dubai, with priority for urgent breakdowns during summer.
The most common causes are low refrigerant from a leak, a failed capacitor, dirty filters or coils, a weak fan motor, or a compressor fault. A technician needs to test the system to confirm which one.
Usually a blocked drain line, a dirty filter causing the coil to freeze and then drip, or a failed drain pump on ducted units. We clear the drain and fix the cause.
Yes, but we find and repair the leak first. Topping up without fixing the leak wastes money. We recharge with the correct refrigerant for your model, whether R410A, R32 or R22.
Most repairs, such as capacitors, drains, fan motors and sensors, take 1–2 hours. Gas leak repair takes 2–3 hours, and compressor replacement around half a day.
Every 3–6 months, because of dust and heavy use. Filters should be cleaned every 2–3 months, and more often in dusty periods.
All major brands, including Daikin, Mitsubishi, O General, Carrier, LG, Samsung, Gree, Midea, Panasonic, Toshiba, Hitachi, Fujitsu, Rheem, SKM, Lennox, Goodman, York and Trane.
Yes. We repair VRF/VRV systems, ducted and concealed units, AHUs and FCUs for villas, offices, hotels and commercial buildings.
A musty smell usually means mould or bacteria in the coil, drain pan or ducts. A deep clean and sanitisation fixes it, and duct cleaning helps if the smell is in the ductwork.
Short cycling is often caused by dirty filters, low gas, a faulty thermostat or sensor, electrical faults, or a unit that’s too big for the room.
Repair is usually worth it for units under about 10 years old. Older units needing a compressor, or R22 systems with major leaks, are often better replaced, and we’ll advise honestly.
Yes. AC breakdowns don’t follow office hours, so we offer evening and weekend appointments across Dubai.
Yes. Our annual maintenance contracts include scheduled servicing, priority response and discounts on repairs.
Fast diagnosis, honest pricing and genuine parts. Cool air again, usually the same day you call.
