Normally, that only applies if you don't take possession of the property, and don't rent it to someone else.Lots of laws here you need to learn, and not easily answered in a generic fashion without knowing the details of your lease or the city/state the property is in.Bottom line, though, if I was you and didn't know all the laws or had the time to learn them, I'd just keep the deposit and tell the tenant they are not entitled to a refund, but they are welcome to sue you and see what the judge says.Then, if they actually sue you, you show up, show the judge the photos, etc.

Speak to a professional and/or supplement the a/c with an in-room a/c or window unit.
