Coming into this class I had no HVAC experience. First day of class I learned more than ever thought I would. If you are wanting to take a good class with a great instructor this is the class for you. Eric, will teach you the class and then allow you to teach the class. This way you are hearing it, repeating, and then re hearing it from your classmates. I have enjoyed this class very much and would recommend it to others who want to further their education and knowledge in the HVAC field.
