Does anyone have any idea what these black stickers are on the ductwork? They felt slightly tacky to the touch. I thought they may have been covering holes, but they were not. They were on all of the ductwork, and I have never seen this before. Any ideas would be appreciated. Thanks in advance.

Larry's got it.
It damps out the duct pop on blower start up and shut down. http://www.acousticalsurfaces.com/hv..._vmax.htm?d=26 He who knows nothing is closer to the truth than he whose mind is filled with falsehoods and errors - Thomas Jefferson - Founding Father |

Never seen it either, but that is what came to mind first too.
Possibly a thinner sheetmetal than normally used and the duct was drumming with the velocity of the air. LEED Green Associates InachiAwardsPortal: Inachi US Member of the Year Award 2009 |
