Next is choosing between Chemical Cleaning vs Chemical Overhaul

Chemical Cleaning is cheaper, faster to clean but not thorough as the unit is not taken down (on site). Chemical Overhaul is relatively more costly, takes a longer time to clean as the unit is removed from the walls or ceiling (off site)
Chemical Overhaul is thus recommended over the other as it is able to chemically cleanse & treat every component and the inaccessible parts of the fan coil.

In Chemical Overhaul, removing the unit from the wall or ceiling (off site) will allow effective cleansing and treatment of every components-parts and inaccessible areas of the fan coil unit.
Can I DIY – service and maintain my own aircon?
You can, but to a certain extent.
You can remove the indoor unit cover (fan coil) to take out the filters to flush and rinse it with water.
You can also use a ‘wet’ vacuum clean to suck out any visible dirt from the coil and fins BUT be sure not to cut yourself or bend the fragile fins. You can clean the outer parts of the indoor and outdoor units but do take precaution with the use of a sturdy ladder and ensure the system is switch off.
Beyond the above simple DIY procedure, it is prudent to engage the services of trained aircon servicing technician on periodic basis for your normal aircon service, chemical overhaul and the more involved tasks of aircon repairs.
Why is the air conditioner leaking water?
One possible reason is that the indoor unit (fan coil) drainage pipe and tray is choked with dirt. A general aircon service & vacuuming should suffice. However, in serious case of clogs, stains and fungi growth in the unit, a chemical overhaul is to be carried out.
Why is the aircon running but not cold enough and the air stuffy?
Several reasons. One is that the refrigerant (aircon gas) is leaking or insufficient. The other is that the indoor unit (fan coil) needs either a thorough aircon servicing or chemical overhaul. Another reason could be that the outdoor unit (condenser) needs a check and servicing.
Why can’t I turn on the aircon?
First, check if the electrical supply is not cut off. Go to the electrical circuit panel to ensure that the fuse is not ‘tripped”. If problem persists, engage a professional aircon servicing company to check on the system.
What are the advantages of regular aircon servicing and maintenance?
The air-conditioning system needs basic cleaning and maintenance.
One advantage is that a clean and well maintained aircon system will be running at its optimal, thus reducing your energy bill. The lifespan of the air-conditioning systems will also be prolonged. Next is the avoidance of nasty surprises and hefty repair bills. Aircon leaking water can also be avoided.
Why is the aircon so noisy?
A dirty and clogged aircon system will tend to be noisy
The indoor unit or outdoor unit may be loose from its mountings. Faulty and worn out parts may also cause the noise.
Please have the aircon checked immediately by a qualified aircon technician.
Why is the aircon emitting smelly and foul air?
Over a prolonged operation, particularly in humid, dusty and greasy environment, the fan coil unit become dirty, stained, clogged and become breeding grounds for bacteria, viruses and fungi growth. This cause the air to be putrid (smelly) and is unhealthy. This result in the aircon unit not operating properly, higher energy bill and the aircon leaking water.
This calls for an immediate aircon chemical overhaul.
