We have a 2016 Silverback 33IK had a noise in duct work under main unit took off return vent covers and discharge vents was able to reach in and remove a piece of clear plastic covering from blue styrofoam insulation. I did not see any metal duct work in the ceiling. I was wondering if someone else with a Silverback could check to see if theirs is like this or if there is metal duct work in the ceiling. This might also explain why after the unit runs it sounds horrible for expansion and contraction. Thanks
