Jerry Ripley, owner and operator of the company "The Air Guy", does air compressor maintenance, installs, and related work. His work is substandard, using used parts in some cases. Does not complete work as contracted, even when confronted regarding uncompleted or incorrect work as per contract. He displays a very unprofessional attitude at times. He is also a liar and a thief. He asked me for full payment before work was completed. Big mistake!
