  • There exist some very low priced “chemical cleaning” work. This so called “chemical cleaning” is merely spraying of some chemical compound on the front surface of the fancoil and the chemical is wash away with some water. This cleaning work is not thorough enough as the whole fancoil is not dismantle down and strip apart for proper chemical treatment. Such shoddy “chemical cleaning” is only able to clean the outer surface but the interior and back side of the fancoil is unreachable. This method of cleaning will also leave residue chemical trapped inside the fancoil which will cause corrosion of the cooling coil. The only proper way of doing chemical cleaning is to dismantle down the whole fancoil which is also what all major air conditioner manufacturer recommends and practices.
