What exam is he sitting for?
Norm Christopherson's book, HVAC Technician Certification Guide, featured at the top of this web site page, is a good practice manual for taking tests such as the NATE and the RSES CM exams. Also probably wouldn't hurt to use it as part of preparing for a state license exam, but for that I'm sure he's gotta know more than just HVAC particulars, such as building codes, business practices, etc.
- Electricity makes refrigeration happen.
- Refrigeration makes the HVAC psychrometric process happen.
- HVAC pyschrometrics is what makes indoor human comfort happen...IF the ducts AND the building envelope cooperate.
A building is NOT beautiful unless it is also comfortable.
My book is not limited to preparing for NATE or the other technician certification exams. It is useful in preparing to take the HVAC portions of contractors licensing exams as well.
In fact, the book is useful to anyone who wants another study resource even if they are not planning on taking any exam. Just reading the questions and considering the possible answers before looking up the answers is another useful method of self study.
