The premier accrediting agency for HVAC training programs are the NCCEA, which is the Partnership for Air-Conditioning, Heating, and Refrigeration, HVAC Excellence, North American Technician Excellence and Research, Environmental Protection Agency, and the Occupational Safety and Health Administration. You MUST select a college that has a minimum of at least one accreditation.
Smaller class sizes are also important, which means you will get personalized help from the program teachers. A good HVAC college will also have an on-campus science lab with modern equipment. Visit the campus and get a feel of the place, the teaching areas, the overall facilities offered and talk to the teachers, if they are available. Also find out whether there is any flexibility in organizing classes for employed students, and also how you might go about procuring financial aid, if you are eligible.
