Jerry does not like to be questioned about his work. He is not very willing to explain things regarding the work you are paying him a lot of money to do. Once your unit is installed, they really want nothing more to do with you. We were told 2 weeks before someone could come out and fix our unit that is almost 2 yo. However, we called another place in Raleigh and they came the same day. Seems like if your company is too busy to service your existing customers, then you need to hire more employees.
