I make this warning as Tom in Nashville retires, the unit I saw from a so called Technician from BC was nothing but a total mess so he can not be rated as a real Tech. He puts all kinds of pictures on his FB page but when you check the work he has done it was very minimal and also what he did do was wrong. There are now about three or four Technicians that have any idea what they are doing left and I myself am overloaded. I am training new guys but it is very slow going. As I hear many complaints about other technicians and some what I call boneheads, there is sometimes the only option to send it to an expert.
