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 on one assistance from the instructors. The best colleges teaching HVAC courses will also have an on-campus science lab with professional-grade tools. Before enrolling make sure you visit and explore the campus and get a feel of the place, the teaching areas, the facilities and talk to the teachers, if possible. You should also find out whether they allow any flexibility in organizing classes for working students, and how you should go about researching financial aid, if required.
