So after the 2nd night on our maiden voyage I heard a rattle right above the quick cool vent. It was loud enough it woke me up.
I took the cover off and as I assumed a piece of the tape had come loose and was flapping.
Then I noticed that on the other side the tape was "sort of" put on between the wood frame and the air duct. I'm going to fix this but I want to make sure it's standard HVAC tape that is used. Here is a pic I tried to take of the offending area. There is about a 5/8" gap between the duct and that exposed wood. So my nice cool air is cooling my ceiling there.
