That's a complex question about implied warranty that probably is affected by whether or not you are meet the legal standard to be considered a merchant of the type of good/service provided and other factors (and the AS IS block definitely discourages people to sue, but you may not actually be able to disclaim the warranty involved, so it may not get you off the hook.)
