My Aircon is Not Noisy Anymore!

So yesterday I did some cleaning of my own, and it worked damn well! To my surprise the noise is gone, no more stupid clicking noise in the middle of the night, I really had a peaceful night of rest, damn shiok, woke up this morning feeling refreshed like never before, almost don't feel like leaving my bed, I also felt that the air is cooler than before.

Now that I think of it, the noise could have come from poorly positioned fancoil unit, I really don't think the cleaning did the job, more like the adjustment and making sure everything is set tightly in place, I think that helped to minimize the vibration significantly and hence removing the noise completely, I don't know, that probably also helped to make it cooler, I guess?
