Split AC repair based on readings, not guesses
Split systems do most of the cooling in Dubai apartments and villas, often for months without a break. Dust and sand clog filters and coils, drain lines grow algae, and outdoor units bake on roofs and balconies.
We repair standard and inverter split ACs, multi-split systems and floor-standing units. Every visit starts with readings: supply and return air temperatures, refrigerant pressure and compressor current, so the diagnosis is based on numbers.
If your AC is dripping water indoors, switch it off and put a towel underneath. It's almost always a blocked drain, and it's a quick fix if it's caught early.
Split AC problems we fix
Not cooling, blowing warm air
Low gas from a leak, a failed capacitor or compressor, a dirty outdoor coil or a faulty sensor.
Water leaking from the indoor unit
A blocked drain line or tray, or an iced-up coil melting.
Ice on the pipes or coil
Low refrigerant, a very dirty filter or coil, or a slow indoor fan.
Outdoor unit not running
A failed run capacitor, contactor, outdoor board or compressor.
Bad smell from the AC
Mould and bacteria in the coil, blower and drain tray. A deep clean usually fixes it.
Noisy indoor or outdoor unit
A dirty or unbalanced blower, worn fan motor bearings, or loose panels and mounts.
Remote or display not responding
Remote batteries or sensor, a failed display board or an indoor PCB fault.
AC trips the breaker
A shorted compressor or fan motor, or a wiring fault. Stop using it until it's checked.

Keep your split AC cooling
- Wash the indoor filters every two to four weeks in summer.
- Book a full service every few months, before the hottest weather arrives.
- Keep the outdoor unit shaded and clear of boxes and plants.
- Set around 24 °C. Very low settings make the system work harder without cooling faster.
- Close doors and curtains in the hottest part of the day.
Split AC Repair FAQs
Why is my split AC running but not cooling?
The most common causes are low gas from a leak, a failed outdoor fan or capacitor, a dirty outdoor coil or a clogged filter. We check pressures and current to find which.
How often should a split AC be serviced in Dubai?
Because of dust and the long cooling season, many households service split ACs every three to four months, with filters cleaned more often by the occupants.
Why is water dripping from my indoor unit?
Usually the drain line or tray is blocked with dust and algae. We flush and clear the drain and check the unit is level.
How much does an AC gas refill cost?
It depends on the refrigerant (R410A, R32 or R22) and on fixing the leak first. We find and repair the leak, then quote the refill.
Can you repair inverter AC boards?
Yes. We diagnose inverter and outdoor boards and repair or replace them depending on the fault and parts availability.
