2013 Sanibel 3500 Air Ducting Noise

I recently developed a noise that sounds like loose ducting or tape inside the air ducting vibrating when the rear ac unit fan starts and stops. I went on top of the unit and had the ac fan started and stopped and did not hear a thing. The noise is in the ceiling just below where the rear ac sits on the roof. No other issues except for this startup/stopping tape like vibrating noise. Any ideas???

Had a rattle noise in one ac duct. Was a loose piece of the foil ducting. Fished it out and ok now.

[B]X2[B] what I was thinking . Have a very slight similar noise in the bedroom when that AC is running but, not loud enough that DW notices .

X3. Had that same issue in our first TT. I ended up pulling off the vent duct and taping the flappy stuff down with some good duct tape. Never had another issue with it.
