Aircon Chemical Cleaning vs Aircon Chemical Overhaul

Most people are not able to differentiate aircon chemical cleaning/washing from a chemical overhaul.

Simply put, general aircon servicing a cleaning of the front panel, replacing the filter which usually gets clogged with dirt, dust, and other debris. However, dust and dirt will accumulate inside the device over time. Sometimes, regular service cannot get rid of the dirt and other unwanted debris.

When that happens, it becomes necessary to use a more thorough and intense cleanup, or what we know as chemical cleaning/wash.

Aircon chemical cleaning (or washing)comprises more than just general servicing. Chemical washing is performed using the hanging tray technique, in which only the front cover and filter are removed, and a tray is hung below the fan-coil and chemical washing is performed at the unit itself. The cleanup will get rid of stubborn stains, grease, and accumulated dust. The evaporator is also removed and the chemical replaced inside the unit.

Though more thorough than general servicing, this method may not be comprehensive enough compared to a chemical overhaul. For example, it may not be possible to reach the water tray behind to remove the dirt and jelly. The dust will accumulate over time and cause leaking.

Aircon chemical overhaul, on the other hand, involves dismantling the whole unit and thoroughly clean every part using chemical wash. As you can see, its cleaning effect is extensive and will remove all the slime and grime from the water tray.

This service will be provided after aircon chemical cleaning, or when chemical cleaning will not be sufficient.

Since the services provided requires more dedicated time and effort, its price is higher than chemical wash, usually by more than 100SGD. We will cover the price range below.

A thorough, well-executed chemical servicing and chemical overhaul offer some benefits. Benefits include lower electricity bills, higher efficiency, smoother running, cleaner (and thus healthier) air.

Why does the aircon need chemical cleaning/chemical washing?

An overhaul is required when an air conditioner is severely clogged or choked, and general service is unable to improve the situation. Chemical-based cleaning is a more thorough method of air conditioner maintenance. It is advisable for those units which are badly clogged. The air conditioner is dismantled part by part and chemically cleaned during an overhaul.

In a chemical overhaul, the aircon is dismantled part by part and chemically wash. It is best recommended for you to engage a professional who does aircon chemical wash in Singapore, compare quotations and select one that is the best for you.

What does chemical flushing and overhaul include?

Aircon chemical overhaul includes:

1. Lubricating the bearing of the fan will eliminate any sound produced when the unit operates
2. Performing thorough checks to the thermostats and the unit’s controller
3. Chemical solutions are used to clean the pipes, blower wheel, and drain pans.
4. Cleaning of the fan evaporator coil to ensure a smooth heat exchange without the accumulation of dust and grime.
5. Replacement of faulty bearings to eliminate any sound produced during operation

Can I do my chemical flushing myself?

It is not advisable to do chemical flushing yourself – if not done correctly, many other problems may occur.
