"Great job and very nice man. I highly recommend!"

"Gregg was very professional and went step by step to diagnose the problem. Additional parts were needed to repair it so he returned the next day. The work was done and all appeared satisfactorily resolved. However, the same issue arose the next day. He returned early and located a burned through wire that appeared to have been placed poorly during the original manufacture. Problem solved no extra "
