Anybody seem to have popping noise in roof air ducts when either AC or heat pump is running and after shuts off. Sound goes from one end to other end if trailer. Vary annoying. 2013 FB.
Only when we were parked under a Nut tree outside Atlanta at Stone Mountain State Park.

Sometimes I've heard a little crackling noise in our bedroom just after the AC gas been running for a period of time. If I remember right the cracking did not last very long. I attributed to either temperature change or sudden change in pressure inside the ducts.
We had a similar sound in the s&b when we first built it...
some 'stuff' was in the ducting and ended up at the vents bouncing around when it came on and off...
builder pulled the vents and it was white 'stuff', light enough that the slow wind would blow it around...
might try to pull the vents to see what falls out
Know ours drove us crazy at first !

I notice the same. I think after time it starts becoming "white noise". IMHO it has to do with temp changes and that its a "hard" ceiling so the sound travels. The longer I am in the couch the less annoying it has become.

Steve & Mickie sounds like you know what we are experiencing. I think it has something to do with the fi-foil not being secured properly and it moves when the air hits it and then relaxes when air is off.
I had the same problem. It was the foil tape they use to seal the ducting right under the a/c. The Professer and I removed the A
a/c and resealed the area. make sure you use a lot of self leveling caulking when you put the a/c back in it's place. since we fixed that problem, no more noise.
