HVAC Magnets

When you decide to pick a HVAC college program, the first thing that you must find out is that the choice of college you have selected is an accredited one. This is ultra important, as it means that the training program provided will be at the required standard specified by approved HVAC organizations.

The premier accrediting agency for HVAC training programs are 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. You MUST select a college that has at least one accreditation.

Smaller class sizes are also important, because then you will receive one on one attention from the program teachers. A good HVAC college will also have an on-campus science lab with modern equipment. Visit the campus and get a feel for the place, the instruction rooms, the facilities and talk to the teachers, if they are available. Also find out whether they allow any flexibility in scheduling classes for students with external jobs, and how you might go about procuring financial aid, if you might need it.

• Magnets have poles designated as north and south. • Magnets have lines of force called magnetic flux. • Like poles repel, opposite poles attract. • When the lines of flux are cut with a conductor, electrical current is generated.
