Complaint Review: Poorman's heating/cooling

Hired this guy last year to fix my central air-conditioning, had a few minor problems during the job, but being contractor myself was understanding. 
Well couple of days ago my couldn't start my a/c , i started fixing it myself , and found out there was a bad wiring in my ac unit, i called harry to come and take look at his work, and hoped he's going to take care of the repairs under warranty, he was rude and denied any responsibility , without even looking at the work. I did the repairs myself, i found some horrible wiring, which was serious safety issue, very sloppy electrical work. Replacement parts costed me $250 plus few hours of labor, i talked to local hvac company and they said cost of repairs (if done by them) would be $6-800
After i was done with work , i figured i write some reviews about this guy - found out he's got already bunch of negative reviews and F rating with BBB .
