The best trade school experience I have had in years! The HVAC training was done by a very experienced and very industry dedicated professors such as Brian Byrom and others with over 35 years experience in the field and a yearly retesting of their own knowledge. The educational part was a lot shorter than a two year college program and 15-30 times cheaper, yet valued by the State as equal in theory and practice to enable one to pass a State Certification exam. I would recommend NARS to anyone in Huntsville as the quickest path to success.
