General Aircon Service or Normal Aircon Wash is carried out once every 3 months. However, after an extended period of aircon usage of 12 months or more, a Chemical Overhaul Service is strongly recommended. This is because stain, dirty, contaminants get lodged in the various parts of the fan coil unit which cannot be easily removed and cleansed during a normal aircon service.
In addition, fungi growth will prevail. This can only be removed with a Chemical Overhaul Service.
Usually, some or all of the following are tell-tale signs to indicate that a Chemical Overhaul Service is due:
Putrid and foul smelling air
Unusually noisy operation
Stuffy air emitted
Constricted air flow
Persistent air-conditioner leaking water
On inspection, the fan coil unit appears stained and moldy and fungi growth is spotted.
Chemical Overhaul Service
Chemical Overhaul covers the following:
Dismantle fan coil and (wall mounted and cassette type)
Chemical wash cooling coil
Chemical wash blower wheel
Chemical wash drainage tray
Chemical wash cover
Chemical wash air filter
Chemical wash fan coil body
Vacuum drainage pipe
Check any faulty part
Check cooling system
Essentially, a Chemical Overhaul Service is done offsite, meaning the entire fan coil unit is removed from the wall or ceiling to allow a thorough cleansing with chemicals. The chemical cleaning process takes almost an hour to clean each fan coil unit. The unit is dis-assembled into its component parts and cleansed chemically. The parts must also be thoroughly rinse with water before re-assembly and re-affixing the unit back to the wall or ceiling.
Chemical Overhaul vs Chemical Cleaning
Some are confused between choosing Chemical Overhaul and Chemical Cleaning. The main difference is that Chemical Overhaul is done offsite (unit removed) and Chemical Cleaning is done onsite.
The onsite Chemical Cleaning Service does not remove the fan coil unit from the wall or ceiling. In this respect, the chemical cleaning process of the fan coil unit is not as thorough as compared to Chemical Overhaul.
