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???
