I have decided to start-up my own small residential HVAC company after working with a nationwide company for over 8 years. I have owned my own company before, altho it was a restaurant not an HVAC company. Did that for 15 years and very successfully until I got burned out. I live in Boulder county, CO. To apply for a license here you are required to pass the N29 Master Mechanical exam. The exam is based on info from 3 sources including the 2008 NEC Handbook. WOW! What a monster that is..... 1500 pages. I don't want to be an electrician, just an HVAC contactor. Do I need to know everything in this huge book?? Does anyone have any ideas on this? Do I only need to study the sections that look like they apply to the HVAC industry?

... Do I only need to study the sections that look like they apply to the HVAC industry?That is what I would do. Talk to other contractors and see what they have to say.

Let's see.


90, 100, 110, 200, 210, 220, 225, 240, 250, 300, 310, 312, 350, 356, 422, 424, 427, 430, 440, 680, 725, and Chapter 9, as applicable.

For most of us, these are the relevant areas if an HVAC guy is being tested on the NEC.

Your jurisdiction may be testing on the complete code. That requires a study course if you are not an experienced electrician. (Experienced at the testing process, that is.)

The test is probably open book but timed. You need to know your way around the book.
