Quick & Basic Troubleshooting: A Contractor's Guide to Fixing Hvac Wiring & Circuits

A very good book for HVAC tech.

Basically tells you order of elimination when servicing or troubleshooting equipment. Would be more usefull to someone starting in the Hvac trade. The order did ship on time and in mint condition. Can't fault them for that

good product

This thin cheaply produced essay by a school teacher covers basics of electrical theory pretending that is useful for someone troubleshooting HVAC equipment. Shows no knowledge whatever of HVAC wiring. Of no value at all.

Thank you.

These are a waste of money. Obviously written by someone who has never worked in the field. I used to work in the field and ordered a couple in the series to refresh my memory and was blown away at how completely useless these books are. Luckily I bought them used but still wasted money.

I would not buy this book if you are looking for any help on Air Conditioning systems.It is very basic and only covers heating systems and thermostatic controls.I hate to be cynical but I found this book not worth the trouble.You would be better off learning the basics of electricity and circuits in a more detailed guide.In all fairness, 85% of all troubleshooting on A/C systems is electrical troubleshooting.This is mistitled in my opinion.

Very informative. Well written.
