<human>: So as the title says, my ex landlord is taking me to court over damages to his house. The only thing I ever did was put a hole in the wall when moving my box spring upstairs, which I fixed btw. Now, I paid a $500 security deposit, which he said he was keeping. 

But here's the good part. I went without a furnace for the whole 6 months I was there. There would be mornings where me, my wife, and my 3 YEAR OLD son woke up and it would be 40 degrees in the house. 

The gas company red tagged the furnace and we told him. His solution? Remove the tag and said it works fine. We told him repeatedly it needed fixed, but always said he'd get around to it.

There were broken windows where my son could reach which he said he'd fix. Never did.

What I was wondering is if I could counter-sue for making me live in those conditions for 6 months and how I would go about doing it if possible. 

Any help would be appreciated. Thank you

Can you condense the text into a few key points?
