These are the recommendations from popular AC manufacturers when it comes to aircon cleaning. Following the advice can prevent your AC from collecting dust or dirt.


LG air conditioner


LG users must clean aircon regularly to prevent possible breakdown while maintaining optimal performance.


According to LG Owner’s Manual, the air filters in your LG aircon must be cleaned periodically. The recommended cleaning interval for each type of filter:

  • Antibacterial air filter: every two weeks
  • Antibacterial filter: every two weeks
  • Plasma filter: every three months


And what about the indoor unit surface and outdoor unit? How often should you clean your LG aircon?


LG does not give specific advice; instead, they recommend users to check and clean it regularly. Suppose you can see an accumulation of dirt and dust on your indoor or outdoor units, it would be better to clean them.


Also, most aircon service professionals recommend that an aircon be serviced (which includes professional cleaning) at least once a year.


Daikin air conditioner


Daikin has something to say for their AC users. First of all, they recommend yearly professional maintenance for your aircon. Then, users need to perform filter cleaning once every two weeks.

For filter cleaning, you can wash it with water or use a vacuum cleaner. Wash in lukewarm water with detergent for filthy filters. Then, dry them in a shady place away from direct sunlight.


Fujitsu air conditioner


Do you own an aircon from Fujitsu? Like the previous brands, Fujitsu recommends homeowners clean air filters every two weeks for normal use. If you use your aircon frequently, it would be better to clean filters more regularly.


Also, they suggest that you must perform preventive maintenance through an accredited aircon service contractor. That ensures your indoor and outdoor units can be inspected regularly in addition to cleaning. Preventative maintenance helps to avoid excessive wear and tear or malfunctions too.


The periodicity for regular maintenance depends on the usage. Still, the general rule of thumb is you should schedule a professional aircon servicing at least once a year.
