National Technical Institute

This experience really was one of the best in my life by far :) I literally walked in determined to sign up to further my education in HVAC-R that day and I did! Our Monday night class was DEFINITELY one for the books and had an amazing opportunity to learn with a group of people I will never forget :) These gentlemen who work here are real professionals and true life long mentors. Hooray to becoming a certified tech!

NTI has the best HVAC program, it was very much worth the cost, which is not that much compared to other programs. They have amazing assistant, Dexter, he is available all the time. They have very helpful teachers, Mark and Casey. They will make sure you know your stuff and make sure you get hired.

I have to say without a doubt that choosing to take the HVAC/R program at NTI was one of the best investments I have made in my life. And future. They have one of the best Instructor/Trainer I have had the privilege of learning from and working with; by the name of Mark Williams.
Give him and National Technical Institute a chance to help change your life too. You won’t be disappointed at all. Thank you Mark and the rest of the Team at NTI. They treat and take care of you like family.

Wonderful experience all around. Ty and Mark were awesome instructors, that were very patient. David was very helpful in answering all of my questions before starting the program. I fully recommend anyone in the local areas of Phoenix or Las Vegas to check this school out if you are interested in a fulfilling career in the HVAC industry.

NTI is a great school. The instructors take the time to make sure you have a full understanding of HVAC. Dexter is the man behind the scenes the help make sure you understand what NTI has to offer. Can’t wait for the season to slow down so I can get back in to attend the electrical class.

This was a very comprehensive course online. The videos and the quizzes really help to build a strong foundation to continue to build on. I did this course completely online and would recommend NTI to anyone that desires to pursue a HVAC/R Certification. The instructors are very knowledgeable, friendly and quick to respond to any question/issues to help on the path to getting certified.

The whole program was great , the instructors take the time to make sure you are getting what they are teaching. The rest of the staff are available if you have any issues. Over all great school at a great price

Even with NTI's price being very cheap compared to a lot of other trade schools, the information and concepts learned are very valuable. It's a very short program too but with the instructors explaining concepts in a very well way, there was not one week where I walked into class and thought that I did not know what to do.

I took the HVAC course, and it was a great class! Mark is an amazing teacher, and you feel prepared when you graduate!
