Sorry to crash your party Stephen, But I am very much in the same boat. I have recently lost my job in manufacturing and even before was considering a job in HVAC. I am 34 and live in SF area. I have been searching the web for classes but the only thing that seems to be available is ONLINE Courses. I am really kind of shying away from that because I am a hands on kind of person. In other words I think I would appreciate the classroom more. And what do the online courses really have to offer?
