Choosing the right HVAC electrical trades study material is less about finding a single winner and more about matching a book to your current training stage and budget. Are you preparing for apprenticeship-level study, working through a residential wiring course, or looking for a broad HVAC and refrigeration reference? Your answer changes which of these four options deserves your money, and the price spread reflects that difference in scope.
Quick take
The decision comes down to depth and condition. The Audel Electrical Course for Apprentices and Journeymen is the lowest-priced starting point and offers a Revised edition in Very Good condition. The two Electrical Wiring Residential copies are identical in price and content, with the main distinction being the condition grade. The National Technical Schools set is the largest and most expensive option, bundling 81 technical manuals with career development materials for someone who wants a broad HVAC and refrigeration archive.

Product notes
Audel Electrical Course for Apprentices and Journeymen
The $20.44 Audel is the lowest-priced option in this group. It is a Revised trade paperback in Very Good condition, written by Paul Rosenberg as part of the Audel Technical Trades series. For an apprentice or a journeyman who wants to brush up on electrical fundamentals, this is a compact, low-cost way to review before moving into residential wiring. The Very Good grade means you are getting a sound copy at the lowest price in the group. The limitation is that this is a general electrical course, not a wiring-specific manual, so it is less helpful when you need a house-by-house wiring reference.
Electrical Wiring Residential (MindTap Course List) - GOOD
This copy is priced at $60.32 and marked Good condition. It is a revised text by Ray Mullin and Phil Simmons, and it shares the same content as the Very Good copy at the same price. If you do not mind visible handling and want to stay right at the $60.32 mark, this copy delivers the residential wiring content without paying for a different version. CDs or access codes may not be included with this copy, so count on the printed book for the reference value.
Electrical Wiring Residential (MindTap Course List) - VERY GOOD
The Very Good version of the same Mullin and Simmons text is also $60.32. If you are already paying that amount, this copy gives you the same revised residential wiring content in cleaner condition. That is a meaningful difference when you want minimal wear on a book you plan to keep as a reference. The limitation is identical: this is a wiring reference rather than a broad fundamentals course, and CDs or access codes may not be included. Among the two Electrical Wiring Residential copies, this is the cleaner way to get the same material.
VTG National Technical Schools Air Conditioning Refrigeration HVAC Course Books
This $150 collection is the most expensive and most extensive option here. It includes 81 core technical course manuals, an original student guide book with handwritten entries from 1978 to 1980, a seven-booklet career development sub-set, and an NTS trade dictionary. The content spans mechanical schematics, wiring prints, electrical theory, residential cooling, and refrigeration, which makes it attractive if you want a historical course archive rather than a single reference. The limitation is practical: this is a large, cumbersome set, and the vintage format is not a substitute for a modern, streamlined textbook.
Final recommendation by use case
If you want the lowest-priced electrical fundamentals course, take the Audel. If you need a residential wiring textbook with the cleanest available condition at the midpoint of the price range, take the Very Good Electrical Wiring Residential. If condition is not a concern and you want the same content for the same price, the Good Electrical Wiring Residential is just as functional. If you want a full HVAC and refrigeration course library with career-development material, the National Technical Schools set is the one to buy.
