What do I do? There is no way to find the place where water is getting in

This is obviously not good. And possibly expensive. But
whatever the outcome, remain calm.

For starters, I was do a complete walk through and around
the house looking for possible clues. Pay special attention
to gutters, drains, and any septic system. Really, really,
look hard (this is not the time for a casual glimpse).
More often that not, clues are there waiting to be found.

This could be a simple case of a gutter blocked by leaves
dumping water at a critical point where it can flow into
your ducts. Even a backed up drain.

You want to know where that water came from. Even better
if you can determine where and how it entered the ducts.
But with every water problem I've ever known, it's
important to establish the source ASAP.

Look at the water levels around the house -- maybe dig
a small hole/trench in the ground next to house to see
where the water table is.

Approach it calmly and systematically. Post again with
your findings and questions.
