When the air-conditioner, condenser & evaporator get badly chocked, (internal & external) normal servicing can't improve the condition. Chemical overhaul need to be applied. The unit needs to be dismantled & strip part by part. Apply the coil with chemical & wash out with water.

Why Does The Air-con Need Chemical Overhauling?

This could be due to the smell of cigarettes, odours or other air pollutants being absorbed into the unit and thus being discharged with the air flow.

Why Is My Air-con Unit Producing A Foul Smell?

1. The spare part might be faulty and needs to be changed
2. The blower and fan-coil may be dirty
3. Vibration noise due to uneven wall surface

Due to lack of refrigerant. Faulty capacitor or fan motor. It may simply need to carry out chemical overhauling, due to indoor coil choked.

1. The blower and air filter is dirty and clogged with dust
2. The thermostat is set too high
3. The unit is undersize
4. The orientation of the room (e.g. facing direct sunlight)
5. The refrigerant gas needs to be topped up

Normal air-conditioning system will have water condensate in the indoor unit (Fan-Coil) & flow out through a drainage pipe. If the drainage pipe is chocked, water will start to leak. When the unit freezes up, water will start to leak too. Call a qualified technician to rectify the problem.
