text: sold house, new owner sueing me for bad furnace. what can i do? furnace worked when house was sold in aug 05 and served on mar. 06.  hot water heat, so very simple.  contractor who did work fleeced new owner.  currently in beginning stages of small claims.  seems like no matter what i do, i am out substantial funds.  anything i can do?  i did nothing wrong here. have a lawyer review your contract.  have the lawyer put a lein for his fee on the house.  the case will probably go away.  ps  any jerk can take anyone to small claims court.
