Problem with a Disclosure Statement?

Sounds to me that you might have a case. Did you get a home inspection before you bought the house? If so it would have turned up these problems. As far as the remodeling if it was done right and is working I don't think they would have to tell you about that unless that is stated on the disclosure statement as a question. But if they say the AC and fireplace works when clearly it does not then you might have a case if they knowing lied about it on the disclosure statement. What was wrong with the AC was it something that could have broken with out the owners knowing (over the winter) or was is missing something that they had to know about. I know you can't now but always get a home inspection before you buy a house!!
