I finally have picked a contractor to install new system ; now the system; I am told the XR is louder by 3 decibels compared to a Carrier he quoted me;(76 to 73) now I ride bikes and a Harley is MUCH louder than a Suzuki say; I know its all relative; this thing is not going to be under my window; how concerned should I be; I can of course step up but with the dehum. system I am putting in I am at my Max price for the package...dogdoc
