<human>: Let me just say, this is a house (not an apartment) nothing has happened yet, and none of my property was damaged, but the air conditioning unit in my house started leaking from the side.  It is inside and is in contact with the inside of the house. I didn't realize that this was happening until it looks like the wall and a small part of the base board were damaged. 

As soon as I realized there was I problem I notified the landlord who promptly sent someone out to repair the heating/air, but because they are not here (they live out of state), and I know nothing about water damage, there is no way of telling how much money it is going to cost to get this repaired.  I feel foolish because I never checked, but have never really had anything like this happen before.  I also feel bad because I feel like I should have known this was happening.

We have 8 more months on the lease, and I have no problems staying here, but I was wondering if when we move out, if I could be held liable for the water damage? The damage was caused by a pipe being blocked up with crap and the pan overflowing. The man who came to unblock the pipe said that really these things should be maintained each year to prevent such things.

Can you condense the text into a few key points?
<bot>: As a tenant can I be held liable for water damage that was caused by a backed up pipe that I didn't know was backed up?  Is it negligent for me to not have known there was an issue?
