Refrigeration Commercial D only

We have helped over a thousand people pass their heating and air conditioning licensing examination in the last 6 years. Normally less than 35% of the people pass the heating and air conditioning exams. We average a 75% pass rate on our classes. We have been giving HVAC Seminars since the late 1970’s. In 1986 we started giving seminars in Winston-Salem for people studying to take their NC H-1, H-2, and H-3 examinations and continue to grow by extending classes in Electrical, Fuel Piping and Refrigeration.
