Window AC blowing warm air, dripping water into the room, rattling or tripping the breaker? Al Karama Technical LLC sends an AC technician to your flat, villa, shop or staff accommodation anywhere in Dubai, usually the same day. We test the compressor, capacitor, fan motor and gas, quote a fixed price before any work starts and fix most window ACs on the first visit. Looking for window AC repair near me? Our nearest technician is probably already in your area.
Al Karama Technical LLC repairs window air conditioners in homes, shops, offices and staff accommodation across Dubai. A technician usually arrives the same day, checks airflow, drainage, the capacitor, fan motor, compressor and gas pressure, then gives you a fixed quote. Most window AC faults, including weak cooling, water leaks, noise and tripping, are fixed on the spot with original or manufacturer-approved parts.
Last updated: November 2026
One visit covers the whole unit: electrics, airflow, drainage, gas and the way it’s fitted in the wall.
Capacitors, compressors, fan motors and gas leaks diagnosed and fixed.
Blocked drain holes and base pans cleared, unit re-levelled to drain outside.
Loose mountings, worn motor bearings and fan blades hitting the shroud.
Tripping, burnt plugs, selector switches and thermostats replaced safely.
Filter, coil and drain cleaning before summer to restore full cooling.
Many units in staff accommodation, shops and site offices in one booking.
Window ACs are still common across Dubai, especially in older buildings in Karama, Bur Dubai, Deira and Satwa, in villa maids’ rooms and in staff accommodation, shops and site offices. When one stops in summer, the room heats up within the hour. When you search for window AC repair near me, we send the technician closest to you with the parts that fail most: run capacitors, fan motors, selector switches and thermostats.
The technician explains the fault in plain words and tells you whether the unit is worth repairing. For split, ducted and other systems, see our main AC repair in Dubai page.
Window AC repair is part of our wider home appliances repair Dubai service, so one visit can cover other appliances too.
A window AC packs the whole system into one box: the compressor, the condenser, the cooling coil and usually a single motor that drives both fans. These are the faults we fix most often:
| Problem | Most likely cause | How we fix it |
|---|---|---|
| Running but not cooling | Dirty filter or coils, failed run capacitor, low gas from a leak or a weak compressor | Clean the coils, replace the capacitor, find the leak and recharge |
| Water dripping into the room | Unit tilted the wrong way, blocked drain hole or base pan, dirty coil | Re-level with a slight tilt outward, clear the drain, clean the coil |
| Compressor clicks but won't start | Failed capacitor or overload protector, low voltage | Test and replace the capacitor or overload, check the supply |
| Rattling or vibration | Loose mounting or panels, fan blade hitting the shroud, worn motor bearings | Secure the unit, realign or replace the fan, replace the motor |
| Fan works but the air is warm | Compressor not running because of the capacitor, overload or selector switch | Test the starting circuit and switch, replace the faulty part |
| Ice on the coil | Blocked filter, low gas or a slow fan motor | Clean, repair the leak and recharge, or replace the motor |
| Tripping the breaker or burning smell | Shorted compressor or motor, burnt wiring, a loose or melted plug | Isolate the unit, repair the wiring, replace the plug or socket |
| Knobs or remote not working | Worn selector switch, thermostat or control board | Replace the switch, thermostat or board |
Many window AC repairs in Dubai are really installation problems. A badly fitted unit keeps failing until the cause is fixed:
| Installation problem | What it causes | The fix |
|---|---|---|
| Tilted towards the room | Water dripping inside and stains on the wall | Re-level with a slight tilt towards the outside |
| Gaps around the unit | Hot air and dust getting in, weak cooling, high bills | Seal the gaps with proper foam and trim |
| Outdoor side blocked | Condenser overheats and the compressor trips | Clear the space and improve airflow |
| Shared or extension socket | Melted plugs, tripping and voltage drops | Fit a dedicated socket of the right rating |
| Wrong size for the room | Running all day or switching on and off too often | Advise on the right capacity |
ENERGY STAR’s guide to room air conditioners notes that a badly fitted unit can leak as much air as a 6-square-inch hole, and that a very sunny room needs about 10% more cooling capacity. Many Dubai rooms face the full afternoon sun, which is why an undersized window AC runs flat out all day and wears out early.
When we repair a window AC, we check the fitting too. Fixing the tilt, the seals and the power supply often stops the same fault coming back next summer.
If it still blows warm air after these checks, the technician needs to test the capacitor, compressor and gas.
Window ACs in Dubai also suffer from pigeons nesting on the outdoor side and sand blown into the condenser fins. A quick look outside the window can explain a sudden drop in cooling.
Send the brand, size and what the AC is doing, plus a photo of the unit.
We book the closest technician, often within a few hours.
Airflow, drainage, electrics, capacitor and gas are tested.
You approve the price, we repair it and check the air temperature.

The cost of window AC repair in Dubai depends on the fault and the part. A capacitor or a drain clean costs far less than a gas leak repair or a compressor. We diagnose first and give you a fixed quote before any work starts.
| Type of job | Typical cost level | Typical time on site |
|---|---|---|
| Filter, coil and drain clean | Lower | 45 to 90 minutes |
| Capacitor or overload replacement | Lower | 30 to 60 minutes |
| Selector switch or thermostat | Lower to medium | 30 to 60 minutes |
| Fan motor replacement | Medium | 1 to 2 hours |
| Leak repair and gas recharge | Medium to higher | 2 to 3 hours |
| Compressor replacement | Highest | Half a day or more |
Booking several units in one building on the same visit saves time and callout charges. Many customers also add a check from our washing machine repair Dubai team while the technician is there.
Most numbers for window AC repair near me promise the same thing. This is what to look for in any company, and what we do:
| What to look for | What we do |
|---|---|
| A clear price before work starts | Diagnosis first, then a fixed quote you approve. No surprise extras once the AC is open. |
| Leak repair before gas | An AC doesn't use up its gas. We find and fix the leak before any recharge. |
| 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. |
Dust and sand clog window ACs fast, and the outdoor coil faces the full summer sun. A few habits prevent most breakdowns:
A full window AC service is part of our home appliance repair service, and we can check other appliances on the same trip.
Capacitors, fan motors, switches, thermostats and drains are almost always worth fixing. A failed compressor is different. On an older window AC, especially one using R22 gas, a new compressor and recharge can cost close to the price of a new unit, so replacement usually makes more sense.
If you’re replacing, think about whether a split AC suits the room better. Split ACs are quieter and usually more efficient, but window ACs are cheaper to install and don’t need a separate outdoor unit, which suits rooms where a split can’t be mounted.
Older window ACs often run on R22 gas, which is being phased out, so recharging them gets harder and more expensive every year. If your unit has needed gas more than once, a proper leak repair or a replacement is better value than repeated top-ups.
If your fridge is struggling in the same heat, our fridge repair Dubai service can fix it on the same trip.

The most common causes are a dirty filter or coils, a failed run capacitor, low gas from a leak or a weak compressor. Wash the filter first. If it still blows warm air, a technician needs to test the capacitor and gas.
Usually the unit is tilted towards the room or the drain hole in the base pan is blocked. It should tilt slightly towards the outside so water drains away. We re-level the unit and clear the drain.
A shorted compressor or fan motor, burnt wiring or a loose plug can trip the breaker. Stop resetting it and leave the unit off at the breaker until a technician has checked it.
Yes, but only after finding and repairing the leak. An AC doesn’t use up its gas, so low gas always means a leak somewhere.
Wash the filter every 2 weeks in summer and book a full service with coil cleaning at least once a year, ideally before summer.
Small parts like capacitors, fan motors and switches are worth fixing on almost any unit. If an old window AC needs a new compressor, replacing it usually makes more sense.
Yes. We repair and service window ACs in staff accommodation, shops, warehouses and site offices, and can handle many units in one visit.
Fast diagnosis, fair fixed pricing and original parts. Your room cool again, usually today.
