HVAC Spells Wealth Books

Posted February 20th, 2012 by ronsmith

“I have been using the HVAC Spells Wealth book since I first heard of it in 1997 at a ComforTech meeting. Over the years I have purchased in excess of 700 copies of Ron’s book and used them while working in distribution. Every new contractor I work with gets a copy of the bestselling book. Ron has become a mentor and friend over the last four years and I consider myself extremely blessed to work with him on nearly a daily basis.”

Brad Hone, Former General Manager at Service Experts and ARS. Current General Manager of Ferguson Nashville.
