I have a standing floor AC Kenwood E-sense, I have been using it for about 3 years. Today, I cleaned my compressor by taking the top off and cleaning the coils with water; I made sure that it dries off completely. Now when I turned it on, it is making a lot of noise. The noise seems to be coming from the connection pipe between the indoor unit and the outdoor unit. My worker might have tilted it from one side while cleaning, but it was levelled later.
