Insulation blowing out air condition vents.

2012 Adventurer 37F. Just started seeing pieces large and small of silver foil blowing out the vents and some stuck in the duct channel mostly when using the rear unit. Should I be alarmed, that this could cause damaged or a fire.I did take the shroud cover off the unit, but the housing is pretty well sealed,(a lot of screws and putty tape on the seams). Everything works fine except for the loose particles all over the place. And thanks for the replys to my last post changed the check valve on the water heater all OK.
Steve.

It may be nothing or it may be a mouse building a nest for the winter. I would set a trap up in the vent with a string tied to it. If nothing bites in a few days it is probably nothing to worry about. My daughter had a nest in her A/C duct in a travel trailer with a roof mounted air conditioner. I can't figure out how the mice could climb up to the roof and then get down into a duct through a blower motor.

It's probably scrap that was left in the ducts. Mine blew out sawdust for several weeks until I removed one of the front vents and found a huge pocket of sawdust that had collected there. I remove that by hand.

We still have silver foil blowing out of the A/C ducts, but no issues because of it.

I have a 2012 Itasca Meridian and also have had pieces of silver tape blowing out of the ducts. Not sure if I need to worry about either.

We had the silver foil pieces for the first year or so, finally have stopped coming out. There have been earlier threads about it as well.

My friend has a 2011 Ellispe. It is a known problem. If you go to Forest City they will pull the a/c and pull out the remaining foil pieces. They were used to line the inside of the Coleman a/c's but either the glue doesn't hold or they got dusty during the assembly process. In any event it is not anything to worry about and will eventually stop. Winnebago does not replace the foil; it really isn't needed. Not to worry.

Thanks to everyone for their input nice to know it's not a major problem. Every now and then, I hear a rumbling sound and a few foil pieces come flying out the vents. I guess eventually it will all blow out. Thanks again Steve.
