HVAC Recommended Air Changes

When you decide to pick a HVAC college program, the first thing that you must ascertain is that the choice of college you have selected is an accredited one. This is ultra important, as it means that the training program imparted will be at par with the standards specified by professional HVAC organizations.

The premier accrediting agency for HVAC training programs are 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, which means you will get personalized assistance from the program teachers. The best colleges teaching HVAC courses will also have an on-campus science lab with professional-grade tools. Visit the campus and get a feel for the place, the classroom, the overall facilities offered and talk to the teachers, if possible. Also find out if they provide any flexibility in scheduling classes for students with external jobs, and also how you could go about requesting financial aid, if you are eligible.
