It depends on the following 2 factors:

1. How often do you use them?

This is the most important factor. Air conditioners that are seldom if ever used may not need to be serviced for years. Those that are used daily or nightly may require servicing every 6 - 12 months.

2. Where you stay.

This may come as a surprise but air conditioners are highly affected by where they are being used. Homes nearby highways and major roads will require more frequent air conditioner servicing than homes that are in the clean countryside. The smog, dust and dirt of city air degrades AC performance significantly and causes most if not all of the indoor allergies and skin/nasal sensitivities.

The AC servicing industry practices chemical cleaning via the usage of various acids. The service includes spraying your AC aluminium fan coils with acid and letting it eat into the dirt and grime buildup before washing it away. This process damages your fan coils causing microscopic holes that allow for mould, dust and bacteria buildup while at the same time thinning them after each service. This is the primary cause of AC degradation over time, reducing cooling efficiency and increasing electricity consumption.

We believe Chemical Cleaning is popular because:

• It is easy.

• It gives the illusion of clean fan coils by the end.

• The usage of consumables allows technicians to charge higher costs.
