Reliable AC repair near me, wherever you are in Dubai

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.

AC gas refilling in Dubai: done the right way

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:

  • Check pressures and temperatures to confirm the system is low on refrigerant
  • Locate the leak, most often at flare joints, valves or the indoor coil
  • Repair the leak by re-flaring, brazing or replacing the faulty part
  • Pressure-test with nitrogen and vacuum the system to remove moisture
  • Recharge with the correct refrigerant type and amount for your model
  • Confirm cooling performance before we leave

Older units using R22 are becoming expensive to recharge. For those, we’ll tell you honestly whether repair or replacement makes more sense.

Inverter AC repair specialists

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.

How much does AC repair cost in Dubai?

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:

RepairTypical timeNotes
Capacitor or contactor replacement30–60 minutesThe most common cause of 'outdoor unit not starting'
Drain line or drain pump repair45–90 minutesStops indoor unit water leaks
Fan motor replacement1–2 hoursIndoor or outdoor fan
Gas leak repair and refill2–3 hoursLeak search, repair, vacuum and recharge
PCB / inverter board repair1–3 hoursBoard repair or replacement, depending on model
Compressor replacementHalf dayIncludes 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.

AC error codes explained

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.

AC stopped in the heat? What to do while you wait

  • Switch the AC off at the remote and isolator if it’s leaking, tripping or smells of burning.
  • Don’t keep resetting the breaker. Repeated restarts can damage the compressor.
  • Close curtains and doors to keep the coolest room cool, and use fans if you have them.
  • Place a towel or bucket under a dripping indoor unit to protect floors and furniture.
  • Look after vulnerable family members. Elderly people, babies and anyone unwell should move to a cool room or space.

How to keep your AC running in Dubai's heat

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:

  • Clean or wash filters every 2–3 months, and monthly in dusty periods.
  • Keep the outdoor unit clear of boxes, plants and debris so it can release heat.
  • Set your thermostat sensibly. DEWA recommends 24°C or higher, noting that each degree higher can save up to 5% on AC consumption.
  • Close curtains on sun-facing windows during the hottest hours.
  • Book a professional AC service every 3–6 months so coils, drains and gas pressure are checked before summer.
  • Don’t ignore small warning signs like new noises, drips or weaker cooling.

Signs your AC needs repair

  • Air from the vents isn’t cold, or takes much longer to cool the room.
  • Water dripping from the indoor unit or ceiling.
  • Ice on the copper pipes or indoor coil.
  • Rattling, buzzing, grinding or squealing noises.
  • A musty or burning smell when the AC runs.
  • The breaker trips, or the unit keeps switching on and off.
  • Your DEWA bill has jumped without a change in use.

Repair or replace your AC?

Most AC faults are worth repairing, especially capacitors, fans, drains, sensors, boards and leak repairs. Replacement starts to make sense when:

  • the unit is over 10–12 years old and needs a compressor
  • it uses R22 refrigerant and has a major leak
  • it has needed several major repairs in a short time
  • the coils are badly corroded

We’ll give you both options with honest numbers.

AC repair for tenants, landlords and property managers

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.

AC repair FAQs

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.
