This is an extremely important factor, as it means that the training program imparted will be at the required standard specified by professional HVAC organizations.

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.

The best colleges teaching HVAC courses will also have an on-campus science laboratory with modern equipment. Visit the campus and get a feel for the place, the teaching areas, the facilities and talk to the senior lecturers, if they are available. Also find out if they provide any flexibility in time-managing classes for students with external jobs, and how you could go about researching financial aid, if required.
