Worm smell 26dbh

[Tngahan]

Just packing up from a great weekend camping and all of the sudden we have a strong worm smell coming from the ac vents. Been fine all weekend until now. Anyone ever had this happen or have any ideas what it could be? Newbie here...

Yikes!
I'd have to know how a worm smells before I could be of any help.

Like it just rained and you can smell the worms that came up to the surface

Could be mildew/moisture build up. If you leave the fan running all the time, you won't smell it.

Might not be a bad idea to check the gasket around the AC unit just to make sure condensation it running down the roof into the gutter vice collecting near the hole in the roof. Sounds like you're sure it's coming from AC vents. I've noticed a similar smell coming from sink and shower drains. Cascade powder took care of that.

Update: went camping a week ago and ran the ac with no smell the entire weekend...not sure what it was but it appears to be gone!

Thanks for reporting back.
