Smell coming from AC vents


Just came home from vacation and the whole house stinks! Smell is coming from AC vents and it feels like something died, I am guessing in the air ducts. ( I have a crawlspace, so I am thinking something got into the ac system that way. Suggestions, recommendations?

Thanks in advance.

I would start by pouring some water down the a/c condensate drain line to fill the trap. Does the drain run to a sewer line or floor drain ??

This time of year a/c condensate traps are prone to dry up and if they dump into a floor drain or sewer they will likely pull sewer gasses through and stink up the house.

Other than that having a crawl space with the ducting down there it is a possibility that something got in there.
