When you decide to pick a HVAC college program, the first thing that you must ascertain is that the destination college you have selected has the necessary accreditations. This is an extremely important factor, as it means that the training supplied will be at par with the standards specified by HVAC organizations.

The most prominent accrediting agencies for HVAC training programs are the National Center for Construction Education and Research, 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.
