Read below for information on the Georgia State Warm Air HVAC License Exam.  All the information needed is on the The Georgia Secretary of State's Website, but I have all the information here as well.  The Ga State Board for Heating and Air or HVAC Construction Industry Licensing Board has several requirements which are covered in the link below. Available classes for Manual J Heat Loss Gain, Manual D Air Duct Design, Manual N Commercial Design, and Exam Prep Classes are listed below. Since 1991, we have helped Hundreds pass the GA HVAC Warm Air License Exam and we have students score 100's. 

Licensed and Bonded





Around 1991, a retired GA Power Company Marketing Executive and his wife started a teaching company called B & G Designs.  Their company helped people pass the Georgia state warm air license exam, and they were the first to offer this service.  Their reputation was known as the “Go to” people for a license.  Others have tried to copy their material, but forgot that the expertise and knowledge of the instructor, “Buck” was the primary reason for high passing ratio’s not printed material.


A GA Power Marketing Executive myself, I decided to get a warm license.  Of course I knew to go see Buck.  During the class, Buck approached me and asked if I would be interested in helping him teach.  He said if I liked it, I would soon have the opportunity to continue the business.  I was honored that Buck had the confidence in me to teach and continue what he and Glenda had worked so hard to build.  I was glad to join Buck and Glenda’s team.  In 2000 Buck retired a second time, and I purchased the business and changed its name to D & M HVAC Consultants, Inc.  I have continued to teach the proven methods ever since and I continue to have high passing ratio’s with multiple students scoring 100.  One of the most rewarding feelings I experience is to have a student of mine call me and say I passed the test and I couldn’t have done it without you!


I believe in a quote I once heard “Feed a man a fish and you feed him for a day, Teach a man how to fish and you feed him for life.”   I teach people “How to fish” the only difference is I do it by helping them get a license.  This is my mission and my goal.  If you do what I tell you to do, you will achieve your goal to.  Thank you for your interest, and I look forward to helping you get a license.  May God Bless You!
