Aircon chemical wash involves a very thorough overhaul of the air conditioning fancoil unit.
This service is needed when a general cleaning of the aircon unit does not improve the condition.

There are many vendors in the market promoting and offering cheaply-priced “chemical cleaning work”. This is not the same as proper aircon chemical wash.
This so-called “chemical cleaning” is merely spraying of some chemical compound on the front surface of the fancoil and the chemical is washed away with some water.
This type of cleaning work is not thorough enough as the whole fancoil is not dismantled down and stripped apart for proper chemical washing and treatment.
Such shoddy “chemical cleaning” is only able to clean the outer surface but does not reach the interior and back side of the fancoil.
This method of cleaning will also leave chemical residue trapped inside the fancoil which will then cause corrosion of the cooling coil.
The only proper way of doing chemical wash on an aircon is to dismantle down the whole fancoil, as per what all major air conditioner manufacturers recommend and practise.
