HVAC Duct R Values

When choosing a HVAC college program, the first thing that you must ascertain is that the choice of college you have chosen has the necessary accreditations. We cannot stress this point highly enough, since it means that the training imparted will be at least as good as specified by professional HVAC organizations.

The most prominent accrediting agencies for HVAC training programs is 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.

Smaller class sizes are also important, because then you will receive one to one help from the instructors. A good HVAC college will also have an onsite science lab with modern equipment. Visit the campus and get a feel of the place, the teaching areas, the facilities available and talk to the senior lecturers, if they are available. You should also find out whether there is any flexibility in organizing classes for employed students, and how you could go about requesting financial aid, if you are eligible.
