Why is my indoor unit noisy?

For those whose indoor unit is causing you to lose sleep every night, it might be due to the following reasons

1) The bracket securing the indoor unit to the wall is not screwed tightly thus causing 'rattling' noise when the indoor unit is in operation.

2) At times, due to the uneven wall, the indoor unit can never be mounted 'leveled' . Thus it is important to choose a solid support.

3) After sometime, there will be dust and dirt accumulated on the inner horizontal fan in the indoor unit. This caused virbrations. (due to 'additional' weight distributed unevenly on the fan, resulting in unbalanced forces)
Clean the inner fan will solve the problem.
** For those having Mitsubishi Electric Easy Clean models, you can DIY.
** For other models, you might have to dismantle the cover first, which is better left the professional, before you can gain access to the inner fan.
(It is not really that hard, just observed the next time someone comes down to do your air con servicing)
** For some models, like McQuay, you just need to unscrew 2 screws at the bottom and you can see the fan. You do not need to take out the cover.

4) If u have used the air conditioner for years, it might be due to the normal wear and tear of the bearing and motor. In this case, you can either change the parts or live with it till you decided to get a new one.

5) It is normal for you to hear creaking noise especially when you on the air con initially. This is due to expansion and contraction of the cover.

air condition is machines. I wanted to say that it's nice to know that someone else also mentioned this as I had trouble finding the same info elsewhere. This was the first place that told me the answer. Air Conditioning Melbourne
