Rating:
Summary: great book!
Review: I have been in the Hvac trade for years, this book has become my Hvac bible. alot of books cover theory on equipment that is obsolete and dont give you you specific info, this book is on the mark for everything an HVAC tech needs in the field. I recommend this book to all who are in the trade.
