Hi, have only been in the hvac field for about two years now. I have taken the Nate test about a year ago around May 2007 I passed the core but was unable to pass the specialty. I want to retake the heat pump specialty. I have a Nate reference manual(the big thick yellow Nate reference manual") I have heard that the Dewalt series book "HVAC certification" would help in passing the test. Would this truly help or is this just a waste of money Iam not famillar with the Dewalt book. Can anyone advise, that is Nate certified?
