A/C issue

I got in my car today and the passenger side carpet looked wet, i called my buddy up and he said it could be from the A/C. has anyone had this issue before and if so can you point me in the right direction to solve the issue. thanks in advance for your time.

Good time to go Mono Blade(lighter weight,better mpg ,less maintenance & better looks).
Temporary solution:
1)Park pointing up hill or under a tree or carport,garage,etc.
2)If parking down hill.It almost has to be flat.
3)Car cover.
