7 Inch HVAC Tee

When you decide to pick a HVAC college program, the first thing that you must ascertain is that your preferred choice of college you have selected is an accredited one. We cannot stress this point highly enough, since it means that the training program imparted will be at par with the standards specified by regulated HVAC organizations.

The most prominent accrediting agencies 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. 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 tuition from the program teachers. A good HVAC college will also have an onsite science laboratory with professional-grade tools. Visit the campus and get a feel of the place, the teaching areas, the facilities available and talk to the faculty, if they are available. You should also find out whether there is any flexibility in scheduling classes for employed students, and how you could go about researching financial aid, if you are eligible.
