Loud Roof Air Conditioners

Has anyone replaced the fan blades on their Coleman Mach roof A/C units? Has this worked to quiet the units? Any idea what year units these work on? Any info would be appreciated. Thanks.

End of 2013, 2014, and probably first of 2015 as far as I know, but probably earlier that 2013 I just wasn't associated with them earlier. RVP went from a six blade to a three blade fan. First pn xxxxBxxxx failed quickly they then went to xxxxCxxxx which was better but still failed. They then went to pn xxxxDxxxx and it has been fine, so just make sure they have the D in middle of pn.

T Busch, here is a link to a nice long thread about the fans. We tried the fans but when back to the old style, still loud on the inside.
