Electricity for Hvac&R a Guide to Troubleshooting: Answerman

Trust me on this. It's not a trouble shooting guide at all. Your text books have better information in them. It just explains things like what a relay or switch is. If you need to know that it might be useful. Good for a guy who knows nothing about hvac or electrical at all.

Not much help even if your new, has to many answers to basic things that one could find better described online

Excellent pocket tool for a new technician. I just tuck them in my meter pouch for easy reference in the field.

not as good as i thought it would be good for a new guy who knows nothing

thanks
