NTI's HVAC Programs

The National Technical Institute offers three Air Conditioning Training Programs that will prepare you to work in the high paying and high demand HVAC/R industry. National Technical Institute’s programs are designed to accommodate your busy schedule and allow you to work as you go to school. You can complete all eight classes in less than five months. Classes are held in the evenings from 5 pm to 9 pm on either one or two nights per week (depending on the class and schedule). Classes can be taken individually or grouped together to complete a program. Each course includes classroom study that is followed by hands on lab experience. This method of teaching allows the student to immediately reinforce the training with hands-on lab exercises and leads to a much more meaningful training experience.

The Basic Air Conditioning and Refrigeration Program includes the following classes:

The Advanced Air Conditioning and Heating Program includes the following classes:

The Advanced Refrigeration Program includes the following classes:
