Window AC blowing warm air, dripping into the room or not starting at all? FixFast LLC repairs window air conditioners of every size and brand across Dubai. A technician comes to you, tests the whole unit and gives you a clear repair plan before any work starts.
Window ACs are still everywhere in Dubai: in older villas, staff accommodation, workshops, warehouses and many Bur Dubai and Deira apartments. They’re tough machines, but years of heat, dust and long running hours take their toll. FixFast LLC offers window AC repair Dubai residents and businesses can book for the same day, for all sizes and brands, from small 1-ton units to 2-ton models.
Because a window AC holds the compressor, both coils, the fans and the controls in one box, our technicians test the whole unit before replacing anything. You get a clear explanation of the fault and a clear repair plan before any work starts, and we test the cooling and current draw before we leave.
Searching for window AC repair near me? Our technicians work across Dubai every day and carry the parts that fail most, so most repairs are finished in one visit, without taking the unit away.
Low gas, blocked coils, failed capacitor, compressor or thermostat. Full diagnosis on site.
Blocked drain holes, wrong tilt, rusted base pans and frozen coils fixed.
Leak found and repaired first, then the unit is vacuumed and charged correctly.
Start and run capacitors, overload protectors, relays and compressor faults.
Fan motors, blower wheels and condenser fan blades that are noisy, slow or seized.
Selector switches, thermostats, remote receivers and control boards.
These are the window AC faults we’re called out for most in Dubai, what usually causes them and how we fix them.
| Problem | Most likely cause | How we fix it |
|---|---|---|
| Fan runs but no cold air | Failed capacitor or compressor, low gas from a leak, faulty thermostat | Capacitor and current tests, leak repair, replace the failed part |
| Water dripping inside the room | Unit tilted the wrong way, blocked drain holes, rusted base pan | Re-level the unit, clear the drains, repair or treat the base |
| AC not turning on at all | Tripped breaker, burnt plug or socket, failed selector switch | Electrical tests, replace the switch, plug or wiring |
| Compressor clicks on and off | Failing capacitor, overload protector, dirty condenser coil | Clean the coil, replace the capacitor or overload |
| Ice on the front coil | Blocked filter, low gas, slow blower motor | Defrost, clean the filter, check airflow and gas pressure |
| Loud rattling or humming | Loose panels, bent fan blade, worn motor bearings | Tighten the mountings, replace the blade or motor |
| Burning smell | Overheating motor, loose terminal, damaged wiring | Switch off at once, test and replace the faulty part |
| Musty smell | Mould on the coil and blower, stagnant water in the base | Deep clean of coil, blower and base pan |
| Remote not working | Batteries, receiver or control board | Test the remote, then the receiver and board |
A window AC is a sealed system. It doesn’t use up refrigerant, so if it’s low on gas there’s a leak somewhere, usually at a brazed joint, the service line or a coil that has corroded through. Refilling without fixing the leak only buys a short time and puts extra strain on the compressor.
Our gas service follows the right order: confirm the charge is low with pressure and temperature readings, find the leak, repair and pressure-test it, vacuum the system, then charge the correct refrigerant by weight to the nameplate figure. If the leak is inside a badly corroded coil, we’ll show you the options before going any further.
The outdoor half of a window AC sits in direct sun, dust and humidity all year. Over time that causes the same handful of problems:
Most of these can be prevented with a clean and service before summer and again mid-season.
Managing several units in staff accommodation, a labour camp, a warehouse or a row of shops? We can check and service every window AC on site in one visit, list the units that need parts, and agree a single repair plan for the whole building, so you can plan the work around your team.
Some window AC problems have a simple cause. These checks are safe and need no tools.
The Dubai Electricity and Water Authority recommends cleaning AC filters at least every three months and setting the thermostat to 24°C or higher. If the unit still isn’t cooling after these checks, it needs a technician.
Book a technician today. We carry common parts and finish most window AC repairs in a single visit.
Send the brand, size and fault. A photo of the unit and its label helps.
Electrics, capacitors, fans, gas pressures and controls tested on site.
You approve the repair plan in writing before any work starts.
We measure outlet air temperature and current draw before we leave.
The time a repair takes depends on the fault, the size of the unit and the parts. We give you a clear repair plan after diagnosis. As a guide, here’s how long common repairs take:
| Repair | Typical time | Notes |
|---|---|---|
| Filter, coil and base pan cleaning | 1 to 2 hours | Fixes most weak cooling, smell and leak complaints |
| Capacitor or overload replacement | 30 to 60 minutes | Common cause of a compressor that won't start |
| Fan motor replacement | 1 to 2 hours | Unit may need to be slid out of the sleeve |
| Leak repair, vacuum and gas charge | 2 to 4 hours | Depends on where the leak is |
| Selector switch, thermostat or plug | 30 to 60 minutes | Burnt plugs replaced with a correctly rated one |
| Compressor replacement | Half to full day | Assessed after confirming the compressor has failed |
Repair usually makes sense for capacitors, fan motors, switches, thermostats and leaks at accessible joints. Replacement is often the better choice when the compressor has failed on an older unit, the base pan is rusted through, or the coils are badly corroded. Many owners now replace old window units with a split AC, which we also repair and service in Dubai, and we’ll give you an honest view of which option suits your room.
Our technicians work on the window AC brands sold across the UAE, old and new.
Capacitors, fans, gas and electrics are measured, so only the real fault is fixed.
Written repair plan before work starts. You approve the repair plan before we begin.
Technicians across Dubai, with common parts on the van.
Most units are fixed in place, without taking them away.
Our technicians cover villas, apartments, staff accommodation, shops and warehouses across the city, including:
Window AC repair often goes hand in hand with regular servicing. These pages cover the rest:
The most common causes are a dirty filter or condenser coil, a failed capacitor stopping the compressor, low gas from a leak, or a faulty thermostat. Clean the filter and check the selector is on Cool. If it still blows warm air, book a technician to test the capacitor, compressor and gas pressure.
Window ACs should tilt slightly towards the outside so water drains away. If the unit is level or tilted inward, or the drain holes are blocked or the base pan is rusted, water runs back into the room. We re-level the unit, clear the drains and treat the base.
Yes, but we find and fix the leak first. Low gas always means a leak. We repair it, vacuum the system and charge the correct refrigerant by weight.
Most repairs take 30 minutes to 2 hours. Leak repair with a gas charge takes 2 to 4 hours, and a compressor replacement can take most of a day.
Our technicians work across Dubai every day. Call or WhatsApp 054 575 4111 with your location and the fault, and we’ll give you the earliest available slot, often the same day.
Often, yes. Capacitors, fan motors, switches and thermostats are straightforward to replace. If the compressor has failed on an old unit or the body is rusted through, we’ll tell you honestly that replacement makes more sense.
All brands sold in the UAE, including General, O General, Carrier, Gree, LG, Samsung, Panasonic, Hitachi, Toshiba, Midea, Haier, Super General, Nikai, Sharp, Daewoo, Hisense, Westpoint and Kelvinator.
Clean the filter yourself at least every three months. A professional clean of the coils, blower and base pan before summer, and again mid-season if it runs every day, keeps it cooling well.
