The most prominent accrediting agencies for HVAC training programs is 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.
It is also important to try and find small class numbers, which means you will get one on one attention from the instructors. A good HVAC college will also have an on-campus science lab with professional-grade tools. Visit the campus and get a feel for the place, the classroom, the facilities and talk to the teachers, if possible. Also find out if they provide any flexibility in organizing classes for employed students, and also how you could go about requesting financial aid, if required.
