HVAC Circuit Boards

When choosing a HVAC college program, the first thing that you must find out is that your preferred choice of college you have chosen is an accredited one. This is an extremely important factor, since it means that the training program supplied will be at par with the standards specified by professional HVAC organizations.

The premier accrediting agency for HVAC training programs is the NCCEA, 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.

It is also important to try and find small class numbers, because then you will receive one on one assistance from the program teachers. A good HVAC college will also have an on-campus science lab with professional-grade tools. Visit the campus and get a feel for the place, the teaching areas, the facilities available and talk to the teachers, if possible. You should also find out whether there is any flexibility in time-managing classes for working students, and also how you might go about procuring financial aid, if you might need it.
