For Daikin, sometimes you need to change the black box sensor or parts and sometimes remove the part linking to the louvre. The latter is to remove the sound of the roller which will still be there but at a slightly lower sound. The good thing is the parts are easily available outside. It is more of an established brand in the market.

The market now is either Midea or Mitsubishi. These two brands keep updating to the consumers’ requirements.

Some still prefer a separate wall switch for each aircon.

Last time came across Sanyo, Toshiba... Sanyo or Fujitsu used to use a Mitsubishi motor. Toshiba has a lower cost than Mitsubishi with similar components except for the difference in dismantling. Mitsubishi has more advertisements.

From wall plug to wall remote and then to wireless remote.

In life, it is whether the manufacturer wishes to make it easier for consumers to change the parts or not. Some remote sensors just need to be cleaned or the short wire changed. Some repairmen were just lazy or didn’t know. They prefer to change the parts and collect the money. Some have 2 sides A and B sensors. Sometimes, I just spray contact cleaner and it does the trick. It is mainly about the accumulation of sticky dirt or rust.
