HVAC Temp Probes

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. This is ultra important, since it means that the training program supplied will be at least as good as specified by regulated HVAC organizations.

The most prominent accrediting agencies for HVAC training programs is the NCCEA, 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 need to select that has at least one accreditation.

Smaller class sizes are also important, which means you will get personalized help from the program teachers. A good HVAC college will also have an on-campus science laboratory with modern equipment. Before enrolling make sure you visit and explore the campus and get a feel of the place, the teaching areas, the facilities and talk to the teachers, if they are available. Also find out whether there is any flexibility in organizing classes for working students, and how you might go about requesting financial aid, if you are eligible.
