Aircon Chemical Cleaning is an advanced aircon cleaning and servicing method to thoroughly remove dirt and stain from aircon parts.
Aircon chemical cleaning is sometimes known as aircon chemical washing. There are 2 main types of aircon chemical cleaning. One requires the dismantling of aircon fan coils for aircon chemical cleaning. This is frequently known as aircon overhauling. The other does not require the dismantling of the fan coils.
Aircon chemical cleaning without dismantling of fan coil
This involves spraying of aircon chemical on the fins of the aircon fan coil and rinsing it. Sometimes it is called on-site aircon chemical cleaning. Such cleaning may not reach many corners and other aircon components. As such, it is not very thorough. Moreover, the chemical solution may not be completely rinsed as there are hard to reach corners and gaps. Some chemicals may remain in these gaps and corners and cause corrosion of aircon components over time.
During the cleaning, chemical should be sprayed from the outside in. Some chemical solution must be rinse within 5 to 10 mins to prevent corroding the aircon fins and coil. The aircon professional should rinse the aircon from inside out so that the chemical solution is not washed into internal parts of the aircon.
Aircon chemical cleaning with dismantling of fan coil (or Aircon Overhualing)
Most of the time, the aircon professional will bring your aircon fan coil to another place for cleaning after they dismantle it. This is also known as off-site aircon chemical cleaning. The aircon professional will take apart the different components of aircon and thoroughly clean them. This is a more effective way of aircon chemical cleaning as compare to the chemical cleaning without dismantling the fan coil. You can also be more assured that the aircon chemical is rinsed thoroughly before the aircon is reassembled. However, this method is more expensive, more time-consuming and less convenient for you as compared aircon chemical cleaning without dismantling of fan coil.
What type of chemical solution is suitable for aircon chemical cleaning?
Chemical solution can have PH ranging from 0 to 14. Zero is extremely acidic and 14 is extremely alkaline while 7 is neutral. For routine detergent cleaning, the PH should lean towards 8. However, for aircon chemical cleaning, the PH should either be 0 to 2 or 12 to 14. If the chemical solution is PH0, it is very corrosive and therefore it has to be rinse quickly. PH14 chemical solution can also be corrosive even though it is alkaline based.
If the aircon professional has a measuring instrument, you may wish to ask him to measure the PH of the chemical solution. If it is PH 5 to 9, the chemical solution might have been diluted to the extend of it being ineffective.
Should you d-i-y or do-it-yourself for aircon chemical cleaning?
It is possible to d-i-y for aircon chemical cleaning. The question is whether it is worth doing it. A person who is not trained in aircon chemical cleaning may take a long time to perform the cleaning on 3 to 5 aircon fan coils. Perhaps it may take a day to do so. Moreover, you have to buy the right chemical cleaning solution and perhaps dilute it slightly to the right PH. You may wish to dilute it to PH3 to 4 or PH11 to 12 as you are a non-expert and may need more time to rinse the aircon. If your chemical solution is PH0 to 2 or PH13 to 14, it may corrode your aircon before you rinse it on time.
Besides the risk of corroding the aircon, there is also the health risk. The aircon chemical may also harm you if you breath the vapour or your skin comes into contact with the chemical solution. In addition, the hassle of cleaning the place up is another headache. Unlike an aircon professional, he should know how to minimize the mess from an on-site aircon chemical cleaning.
