NTI’s HVAC Programs are broken into nine easy-to-manage courses. You can advance to a job-ready HVAC (Heating, Ventilation, and Air Conditioning) technician with hands-on training. Our HVAC training program is flexible to fit your schedule. TOOLKIT, BOOKS, AND COURSE ARE ALL INCLUDED WITH TUITION! As a next step in HVAC training, National Technical Institute also offers three additional courses as a part of our program. These more advanced courses allow students to move beyond residential and small commercial HVAC systems into “central plants” in large commercial and industrial buildings – such as casinos, hospitals, office buildings, and manufacturing plants.
