Here are the signs that your split AC needs cleaning:
One of the first signs is slow cooling. If your room takes much longer than usual to become cool, dust may be blocking the filters or coils.
Weak airflow is another common sign. Even when the AC is running, you may feel less air coming from the indoor unit.
A bad or musty smell from the AC can also indicate dirt, dust, or mould buildup inside the unit.
In some cases, you may notice water leaking from the indoor unit because dust has blocked the drainage system.
Higher electricity bills without any increase in AC usage can also point to a dirty AC, as it has to work harder to cool the room.
You may also see dust particles coming out of the AC vents when the unit is running.
If you notice any of these signs, it is a good idea to clean your split AC to restore proper cooling and performance. I hope this helps you.

Here is how often should a split AC be cleaned for optimal cooling.
You should clean the air filters of your split AC once every 15 to 30 days.
Filters collect dust quickly, especially if you use the AC daily.
Clean filters allow air to flow properly and help the AC cool the room faster.
You should get the indoor unit cleaned every 3 to 6 months.
Dust can build up on the cooling coil and blower inside the unit.
A proper cleaning removes this dirt and helps the AC work efficiently.
You should also clean the outdoor unit every 6 months.
Leaves, dust, and other debris can block the outdoor unit.
A clean outdoor unit releases heat properly and improves cooling performance.
I hope you now have a clear idea of how often a split AC should be cleaned for optimal cooling.
