Hello Kefah, so good to read you again and that you are well.

The sound to me was like that of a drip of water hitting the bottom of a metal case.

u mean from sweating water on pipes?

or water with ***** inside pipe


i dont think its sweated water on pipe

and if it was refrigerant issue
why not fixed when bleeded ***** then cleaned with r11 and recharged
