im sure there would be a limitation, but to make someone whole it needs to be fair,  and the award may be for more than you may expect, WI is a pretty LL friendly state for the most part,  also keep in mind no one is proving the actual cost, and carpet and pad as well as installation costs have a wide range of prices. 

I bet a lot of the smell is hanging out in the carpet and pad as well as in debris in the coil if filters weren't changed frequently.  

I've pad a few hundred for a small house.
