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 at least one accreditation.
It is also important to try and find small class numbers, which means you will receive one to one attention from the instructors. The best colleges teaching HVAC courses will also have an on college science lab with modern equipment. Before enrolling make sure you visit and explore the campus and get a feel for the place, the classroom, the facilities and talk to the faculty, if they are available. You should also find out if they provide any flexibility in time-managing classes for working students, and how you should go about procuring financial aid, if you might need it.
