The premier accrediting agency for HVAC training programs is the National Center for Construction Education and Research, 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. Select a college that has at least one accreditation.
Smaller class sizes are also important, which means you will get one to one help from the instructors. The best colleges teaching HVAC courses will also have an on-campus science lab with professional-grade tools. Visit the campus and get a feel of the place, the instruction rooms, the facilities available and talk to the teachers, if possible. You should also find out whether there is any flexibility in organizing classes for students with external jobs, and how you might go about researching financial aid, if you are eligible.
