    lineset temp

    Are you going to leave it at that or admit that I was right? If not can you explain how what I did was wrong?

    The noise goes down to almost nothing. I guess 100% quieter would have been more accurate. It sounds normal but when you put the filter back it the tone changes and it sounds like it's being...
