National Technical Institute

Recent NTI graduate here, if you are considering this school for any reason JUST DO IT!! I was hesitant starting the HVAC program but shortly after I was equipped with so much knowledge and confidence. My instructor Mark, was the best of the best. Mark was extremely patient and understanding which made learning so much easier. There is nothing I would change about NTI or the HVAC program except for the fact that I wish it lasted longer! Time will fly by here and you will be certified before you know it. Seize your future let’s go!!

One of the best decisions I’ve made by far. Just a couple months ago I was at a dead end job, now I’m looking forward to a rewarding career. Mark, my instructor was very wise, offered great knowledge based off of his own experience. Couldn’t have asked for a better teacher. If you’re looking into getting into the trade, this is the perfect place to start.

Experienced and knowledgeable staff who are friendly. They have super flexible and were willing to work with me on rescheduling classes when I missed one. They give you nice name brand tools on graduation not the cheapo stuff a lot of places give out. I did the HVAC program and plan on returning for the Electrical and then the plumbing classes

Before enrolling to NTI, I was a bit hesitant, electrician is something that you really know what your doing, I can be dangerous working with live current, however this has been one of the best investments I’ve ever done in my life. I have learned so much during the past months. The way that the school program is designed it’s very convenience, I can study at any hour in my home and practice in the lab once a week during 4 hours. One of the best things is getting support from experienced teachers, specially from Colin, whom shared so much knowledge even during weekends or Fridays nights, the school is very flexible too, letting me take some classes and practicing during the week and hours before beginning of each class, Colin is the best, he always having the best attitude, but he’s jokes mmm he definitely need more practice on that :P. Friendly learning environment, exceptional facilities to practice and learn. This is a game shifter for those who want to get into the field quickly, i receive more than 3 job opportunities during the whole program that was amazing. Kudos NTI!!

This schools is 100% perfect for me. My instructor Mr.Hunsley, he’s so prefect and very smart, cool, compassionate and funny. Mr. Jackson, he’s so on top of all your needs and making sure you got a proper training and graduated on time. Ms.Breann, she is very helpfully helping me getting in the electrical field on time and so helpful with financial tuition. I’m strong recommended anyone who want to attend any programs at NTI Phoenix.

Attended the HVAC Fusion course with Mark as my instructor. Felt like between the videos and the lab I am prepared to be an efficient team member of a HVAC COMPANY. Mark was an amazing instructor, very personable and made the class enjoyable. Highly recommend the HVAC program @ NTI.

I did the plumbing program here, came to nti knowing very little about plumbing, and I’m leaving very confident for my first plumbing job. George the instructor is very smart and experienced with plumbing, he was a great teacher. 10/10 program

Very pleased with my time at NTI. The company I currently work for enrolled me to this school and they couldn't have made a better choice in schools! I really liked the fast paced and hands on training that i received. Mark was my instructor and he was absolutely amazing. His instructions were always very clear and was always there to answer any questions i had and explained things in ways to make it easy to understand. There were even some other instructors there that were also very willing to help and answer any questions. Overall a fantastic school and would recommend anyone to this school wanting to get into the trades!

Outstanding. Online videos grouped by subject so you can watch and review as many times as necessary, then attend a weekly class to reinforce the lessons and apply with hands on instruction.
The instructors are very knowledgeable, patient, friendly and make the learning a fun experience.
Always available during the week if you want hands on experience outside of the weekly class. Day and night classes to accommodate schedules.
I personally went Wednesday nights and did some week day extra hands on when my schedule allowed.
Casey and the Marks were amazing. Between the years of experience and the genuine bond we built, I thrives in the classes and was a bit sad to graduate and see it all come to an end.
May take an electrician course just to see the guys again!

The staff at NTI are wonderful!! I loved everyone from Chris to Rick to Mark!! I actually know Chris from QuikTrip because I work there and he use to work there! Mark is an amazing instructor that taught me a lot in a small period of time!!

Nti was a great flexible environment to learn in. Having a work and family life classes were easily attained. Mark our teacher was very knowledgeable and available for questioning.

Went through their plumbing program, took like 6 months on my own time and a week in person, and got offered two jobs just a couple weeks out. Starting my apprenticeship next week. Good program to kickstart your life. They take care of you. Looks great on a resume as well.

Very good program. Great instruction and office staff. Very helpful and detailed. The hybrid online courses and in person labs are great for hands on experience. They offer assistance with employment after graduation too which is awesome.

NTI was one of the best learning experiences I’ve had. My instructor, Mark, was very easy to learn from because of his passion for the industry. It’s was a relaxed environment where the lessons began at the simplest things and then progressively built on that foundation until the process of troubleshooting became second nature. So glad I did this

Hands down the best decision I’ve made in my adult life! Colin and his team not only prepared us for joining the plumbing career field, but he also set us up for professional success. With the help of NTI, I received a job within 3 weeks of starting the course. Thank you, NTI!

The entire experience on campus was great. I was enrolled in the electrical course, and Ralph was my instructor. He did an outstanding job of keeping us engaged and breaking things down. I will highly reccomend NTI to anyone looking to get into the trades.

My entire experience from NTI Phoenix was great from beginning to end. Back in November I took a tour with Dexter who was extremely professional where he further demonstrated what goes on within the facility and how the whole process works for the HVAC-R course. I knew from the moment I walked in that this was the school I wanted to follow through with and he just reassured that with the information he provided on the tour. My instructors, Jared and Casey, were awesome and I was really able to understand new concepts due to their methods of teaching and the overall in class environment that they provide. I strongly recommend that anyone looking to get into the trade and also get an education go to NTI Phoenix. I was actually able to get a job in the field before even finishing the course and I credit that to the information and skills I was able to acquire through extensive notes I took at home, in-class labs, and questions I asked my instructors. It’s up to you. You have to want it. You will succeed with the right mindset; something I had to learn. Thanks Jared and Casey!

This is a good place they will teach you some of the things you need to know but the thing is it's not worth the $6000 due to the fact that you aren't gaining an actual apprenticeship. A real apprenticeship cost $6000 so you guys do the numbers and do the math you're better off just going to the Phoenix JATC.

The classes were great and Mark W. Is an amazing instructor. Kacey and Ricky are also very knowledgeable. I’d definitely recommend NTI to anyone interested in a career in HVAC. I’m so glad I attended this tech school.

An amazing experience at this outstanding school. Everything you need to know is provided, not just paperwork but a lot of hands on training. The whole staff is nice & friendly which makes it a whole lot easier to communicate and ask questions whenever you need some help. They’re all also really supportive and always trying to make sure you’re on track to success. Ty with the perfect videos that explained everything you needed to know. Mark with being a supportive great instructor helping you out through the hands on training. David & Dexter always communicating with us throughout the days making sure we are doing okay & staying on track. All together they make a great team that literally won’t let anyone stop them from seeing their class move forward! I would highly recommend this school if you’re interested in HVAC!

Great experience and excellent school. Very easy class schedule to work with. I came in not knowing much about plumbing or tools in general and left with a pretty good knowledge that is going to help me in the long run. If you are looking to get a job in your field, NTI is partnered with great companies that are looking to hire students. I am one of a couple of students that received a job before graduation. Besides being a four month course and way cheaper than any other trade school. Colin is an excellent instructor he takes the time to work with each student individually and does a great job breaking down everything step by step. He helps guide you and does his best to prepare you for when you're out in the field. I highly recommend NTI to anyone that is looking to better their life by far one of the best choices I made.

NTI is absolutely amazing! I HIGHLY recommend to anyone looking to get into a trade. I've taken several college courses on different campuses and with different instructors, however I can confidently say Mark and Casey are easily the best. This isn't just some trade school with staff trying to take your money and get you out the door. They actually treat you like family and help you on and off campus. Around the thirteenth week I shared some personal issues and how important it was for me to complete this course and get into a career. Within hours they had me in contact with a contractor, and a week later I was hired. I love this place and it's staff so much that I want to come back for the electrician course and/or the plumbing course. If you're having any kind of second thoughts, please know that I have an Alabama public school education yet Mark and Casey made everything relatable and make sense to the point that I'm already confidently working in the field. They are amazing and you all deserve to have some amazing in your lives.

Very good school with extremely knowledgeable and helpful instructors. Casey and Mark were great to learn from. They would both help students as much as possible but also gave us the freedom to try to figure out problems for ourselves. Completely life changing experience, I just wish I would have done it earlier. This school even helps you find a job. They Literally send you contact info on companies looking for techs. Can't say enough great things about this place. If you're looking to start a career in the trades NTI is the way to go.

I had a great experience with the program. I like the convenience of the schedule and the flexibilty. Highly recommend +++

just recently graduated from the electrician program and I have no regrets. everyone is very helpful, especially my instructor Ralph. He assisted me in how i would move forward in this career. i recommend this trade school over any, to anyone!

Mark and Casey were great instructors! They have plenty of experience and will help you with everything, every step of the way, even finding a job. Very much hoping this was a life changing experience for me!

I’m a recent graduate of the program and a big fan of the team. I started my new job in HVAC the same day I graduated due to NTI helping me find my job. The instructors, Mark and Casey of the phoenix branch were incredible and very accessible. There have been times already that I’ve had to call them for some help remembering some of these new skills and they have always made themselves available to help in any way they can. Highly recommend this school

NTI was an awesome experience! Every single hands on lab was really in depth and I was always excited for the next one. Coming out I feel prepared to enter the HVAC trade. Jared and Casey were great instructors that were always helpful every step of the way.

I Graduated the HVAC fusion course two days ago and I already have a job offer and another interview for two very well known HVAC companies that service the whole valley. The hands on labs are awesome and a great way to learn well with hands on experience. Mark and Casey are great instructors and have a wealth of knowledge to share. Take this seriously and study hard and you will learn a lot, you will even be EPA 608 Certified as a Universal Tech by graduation!

What a great experience I came in to check out the school and ended up starting school two weeks later! The videos were great they walk you through the whole theory and process of refrigeration and the instructors in the lab love there work and want you to succeed! thank you Cacy and Jared for caring about our future and the responsibilities that come along with the trade you guys rock!!

Graduated from the HVAC program, and it has been one of the best choices I ever made. Learned so much so quickly! Mark and Casey are two of the most knowledgeable guys I’ve ever met, and are beyond amazing at sharing that knowledge with their students. Can not thank them both enough!

Do yourself a favor and quit looking at reviews, AND GO TO NTI. You will not regret it.

I was enrolled through my current job at NTI. The amount of knowledge I was able to attain while there and through the online courses has definitely helped me better understand my job more! Mark was an amazing instructor and the support while doing the online schooling was great! Would definitely recommend for anyone looking to certify in a trade!

I've recently completed the HVAC 4 month program, and it was an amazing experience . I was debating whether or not I wanted to get into the field but NTI made the decision a whole lot easier. The school was cheap compared to other schools , conveniently located, and had hands on learning. My instructors were Jared and Casey . These two have a LOT of experience and answered any questions I had. Whenever situations came up where I wouldn't be able to make class, Casey was always there to help me make the class up and I really appreciated that . The feeling of getting your tool bag and certificate at the end alone made the whole experience worth it. Thank you guys for everything!

HIGHLY RECOMMEND! Great value for the knowledge and experience! Both Mark and Casey did an awesome job with breaking down concepts, one on one individual guidance and really care about the students and program. Shout out to Dexter for always being available to answer questions! The school provides every resource to be successful and push your skills. Prepares you for the Certification and a job right out of school!

My experience at NTI was great . The whole team of teachers and administrators want to see you succeed and they are always there to help every step of the way . Mark and Casey are awesome hvac teachers , they provide all their knowledge and experience to you face to face. They don’t bore you with lectures and endless notes in a classroom . Everything is hands on! This was great for someone like me who learns the best hands on. This was a great program to be apart of, I would recommend NTI to anyone looking for an awesome hvac training

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

Very down to earth staff and instructors. They will go out of their way to help you. With that being said, you have to put in the work and make plenty of time to study. If you do that, you will learn plenty, and even more so when you get a job.

Best school to get into the field quickly. 16 weeks went by in a flash and I encourage anyone who is looking for a career in HVAC trade to call Dexter at this school. Absolutely painless process from start to finish. Mark and Casey were the best instructors, they always reassured I knew I was doing everything correctly. Can't wait for the future now.

Six months after graduation and I am FINALLY writing this review. Apologies to NTI for the long delay, let’s just say I was on Hawaii time:)

This program is nothing short of amazing. I originally came to NTI after already going through a semester at the community college program for HVAC and refrigeration. Because of Covid, we couldn’t get back into the classroom and lab and I really didn’t have any desire to go back to that program because of the pay said it was going.
One quick call to Dexter, and I was in the next day for a tour and explanation of the program. This is a fast paced, semi self-directed program. You have to be disciplined enough to do the work before you come into the lab, and the instructors Mark & Casey are a great duo to help you apply everything you’re reading/listening to.

I really appreciated the extra time the instructors take outside of the scheduled lab days to help you on anything that you have questions on or processes that you don’t fully understand. This was way different than what I experienced at the other school, and I really felt like they were interested in my personal success.

I now help run a family refrigeration business and am applying everything I learned while at NTI. Highly recommend this program!

Awesome school! Very easy schedule for someone like me who has a hectic schedule with work and kids. Very friendly staff who were very informative from the time of joining to the time of graduating. Always answered my questions.

Coming from someone with no knowledge of HVAC, I will say when I started it was frustrating, but the more time I spent studying and learning it, the more I grew to enjoy it.

My instructor was Mark, Mark always answered my questions and if, if you wanted to stay later or come in earlier never hesitated to mention to us Hey guys don't forget you can always come in earlier or stay longer if you want to work in the labs or are having trouble understanding something let me know. There was never a time Mark did not state that to us or allow for us to stay later.

The labs were very hands-on, I will say hands down I loved my experience and my time here and it was a great learning experience. One thing is certain and should go without saying you get out of the course what you put in, definitely worth the money and look especially if you're looking to get into the field of HVAC.

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!

Great school! Very easy schedule for someone like me who has a hectic schedule with work and kids. Very friendly staff. The Instructor, Mark, is very informative and has a no-bad-question policy. Very hands-on when you are in the lab. Hands down loved my time here and was a great learning experience. You get out of the course what you put in and more!

Excellent experience! The educators are all professional, friendly and knowledgeable. I would and will recommend to anyone interested in the trades. Thank you to Casey, Mark 1 and Mark 2. Shout out to Dexter too!

This was a great experience! I am very happy I decided to go with NTI. Everyone here was awesome and attentive to my every need especially instructor, Mark.
He was very informative and clear with instructions and why things are done the right way. I took a lot from that because when I am in the field I will applying those techniques! They TRULY get you ready for the carrier field and you get countless hours of using their equipment for hands on!

Thank you NTI Team, you all have been awesome!

Going to NTI was the best decision Ive made in terms of my career. I went from zero knowledge to being employed in the HVAC industry just under 6months thanks to the amazing instructors (Mark & Casey) who taught and guided me through program. I will be forever grateful to NTI for helping me add more value to myself.
To anyone wondering if they should do it, JUST DO IT. It’s worth it!!!

As a Plumber/HVAC Tech with over 20 years of experience and now a manager of a Phoenix Plumbing company, I have to say that I am very impressed with the school, faculty and the programs. I have hired their students and alumni, it has been a great experience with the people that I have hired. They have realistic expectations of the trade and are prepared to contribute.
When I am looking to hire, they are going to be my first call in the future!

The instructors are very helpful and patient. I had zero knowledge of HVAC/R when I started. I was nervous but went through with it and I’m glad I did. Now I know as much as they taught me and I feel very comfortable getting a job in the field. Worth every penny.

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.

My name is Mike and I’m from NTI Monday Class. First of all I would like to thank all the staff and My teachers. Mark and Casey are very patient and calm when it comes to you not understanding and stuck on a matter. I recommend this school to anyone that wants to get into another field of work. This course is 16 weeks but it does go fast. I just graduated today and I’m pumped ready to work. So just give them a try you have nothing to loose.

The only word I can use is awesome. The teachers and the front office were awesome. They use hands on and for people like me that's the only way to learn and they understand that. Mark and Casey helped so much. They didn't just give up once you couldn't get something they walked you through it and made sure you understood before moving on. Such great teachers. David and Decker helped me find a job before I even finished class. They all went above and beyond for me and the students. I can't thank them enough for giving me this opportunity I currently have. If you are considering this school do it. Don't wait!

Hello this is Daniel Lopez a graduate from NTI HVAC. Just wanna say thank you very much to all the NTI staff teachers and administrators, some very helpful people that helped extensively throughout the course was Dexter Mark and Casey which I am very grateful for. Definitely recommend this school to anyone looking to forward and be successful in their trade/ career.

- Daniel L.

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.

Since the first day I signed up for class, I was full of hope and excitement. Dexter Bethers always kept an eye on my progress and would always respond to any question or concern I had. He is even helping me with finding a job, so it isn't like any other schools I heard about because they really treat you like you're a member of family. If Dexter is taking care of your path in NTI you don't need to be afraid of anything! I passed my EPA, because of the easy and understandable videos you go through during your 16 week program. My teachers Jared Beaulieu and Casey Kazee, always explained every detail and answered any question I had. Jared is a every good instructor plus he is working in the field, so every week he had some interesting stories from work so for me a person (who's entry level) is so much fun to hear or see how the trade really looks like. It was a great 16 week program. Dexter, Jared, Casey- thank you for everything!

Outstanding program! I work long hours, have 3 kids and needed a school with flexibility. NTI exceeded expectations! I attend the AM classes and Mark was my teacher. He made everything easy to understand and if you had a question, he would take out to the shop and show you first hand. These are the little things that made a huge difference to me. I need to see it, don’t just tell me. I feel like we had a strong class because of the one on one attention we were able to receive. EPA prep was perfect! My class passed the EPA day and can’t wait to get started in the industry.

By far the best hvac school you could go to in the Phoenix valley. I really liked how flexible the schedule was. The instructors were great and very knowledgeable!

My name is trevin sons and I have taken a course on NTI's electrical program. First off I want to say, I came in with basic knowledge of how to wire in a outlet and switch due to working with my uncle. Further more I learned how wiring in 3 ways and 4 way switches, and also learning how to use a conduit bender at the end of the classes. If anyone is wanting to get into the field of hvac, plumbing, or electrical than this is the place to do it. They also offer the osha 10 for anyone who is starting their path through a very high demand work force. At the end of your education you will receive a bag full of all the basic tools you will need, and also even after all the classes are done they will try to help you get the job you want. I hope this information is valuable to anyone who is wanting to be in this field and I am sure you'll have fun and be able to learn if you decide to take this course.

Attending NTI was one of the BEST decisions I have made my entire life. I was on the fence about attending school during the pandemic, but I'm so glad I overcame my fear and did it. I don't have any regrets. The staff was professional and courteous from the moment I walked in the door. David and Dexter walked me through the application and financial process step by step, but I would be remiss if I did not give a BIG SHOUTOUT to my Instructors Mark and Casey. I can't say enough good things about these guys. They know their stuff especially Mark whose been in the business for 30+ years. I also met a great group of classmates that are like family to me now. We were a close group that helped each other out along the way and we were the last class of 2020 and the first graduating class of 2021. That's just special by itself. Sometimes in life you have to stop thinking about things and just do it. So, this message is for anyone on the fence about whether they should attend NTI and whether they believe NTI is the right school for them. Allow me to answer that unequivocally by saying IT IS. Stop thinking about it and do it!!!

REVIEW FROM A WIFE'S PERSPECTIVE!
I did not take this course, but my husband did! He graduated tonight as well as the rest of his class. Great job guys!
When my hubby enrolled, he had the normal queries such as How much work is this going to be and How much of my time is this going to take up? Well let the wife tell you...it was just the right amount. Classes consist of short online videos that you can watch at your own pace each week. These videos are very easy to listen to and follow. The video instructor Ty became a new voice member of our home. In between work, hanging out with the fam and playing video games etc, my husband had PLENTY of time to watch the videos. Every Weds he got to go to the institute and enjoy hands on work with actual air conditioning units! He was always excited to go and heck...one night a week to myself for a few hours??? NICE!
The final weeks were closing in and it was time to prepare for the final test. *GULP*. Me being a test nerd, I volunteered myself to help him study. We made flash cards and watched videos and it was so much fun! The goal was to study to get 100%, not just PASS. Shoot for the moon and maybe you'll get close! Needless to say, he passed with flying colors! Proud wifey here!
The super amazing added bonus was, because I had been involved with his studying, all the infinite amount of HVAC information was now in MY brain! I decided to watch a few of Ty's videos. They were very easy to follow and Ty is actually kinda funny. I had zero interest in HVAC before. Not anymore.
Would you believe I went to his graduation tonight and took the final EPA test myself and passed!! If I can do it, you can! I highly recommend this course to anyone and everyone. It is a wonderful start to a great future. Shoot for the moon!!

I am very pleased with NTI and the instructors in my class Casey and Mark, they did an except job in teaching the class and getting us prepared for a job. Would highly recommend going to NTI

Every Master Was Once A Beginner And There's No Place Better To begin Than NTI. The Instructors Are Extremely Knowledgeable. Dexter In Particular Goes Out Of His Way For All Students. I Highly Recommend NTI. Best Decision I've Made In My Professional Career.

Definitely a great school to learn this HVAC/R. Had wonderful instructors that were patent while we learned how to do things, and very encouraging through out the entire class. They teach you everything you need to know for both the EPA test and for your career.

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.

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.

Mark, Casey , David and Dextar - remember these names (well David will be based out of Houston) because these guys are EXCELLENT! They lay it out straight , taking the time to help each of us understand this essential trade - they’ve encouraged us, texted us, emailed us, stayed top to ensure we are becoming the technician we are supposed to be. If you were thinking about joining the team ? Do it - one of the best decisions I’ve made in my 30 years. Went from security officer killing my mind to now officially certified hvac technician-these guys made sure I had amble job opportunities thrown my way - I graduated today and will start work tomorrow. I look forward to continuing my relationship with NTI because that’s just how they roll. Get in go speak with Dextar , tell them “Billy White” sent you or don’t because they will treat you right no matter who sent ya! Jump in! The waters fine!

Just graduated 11/4/2020. This program is awesome. The staff there is amazing, friendly and very helpful. I didnt have a ged but they have a equivalency test that was super easy. From what I hear other schools cost 2x as much and they're twice as long. I highly recommend this school. Even when you graduate they will still help you out with any questions you have.

There are a few things that sold me on NTI.
1: Lecture is covered by way of online videos that you watch from home. This allows the time spent in class to be committed to hands on application.
2: You attend class in person once a week, however, you are encouraged to come in and practice things learned whenever you'd like, during operating hours. Having the lab open for the students in this manner is totally awesome. You are not restricted to 2hrs a week or 3hrs a week of practicing a new skill. If you want and have the time, come in and practice using you multimeter 10 - 15 hrs a week or any other skill learned, its ok. You will not get access to the lab at any other school like you will at NTI.

You get two Instructors Mark and Casey. That's correct I said two. I like both these guys a lot. They were both ready to engage with the students and answer question when asked. None of the students were frustrated by the instructors lack of simple straight forward explanations. I experienced this at another school that I attended and that was one of the main reasons I decided to attend NTI. We're students, we don't know what we're doing, recognize that and keep it simple and straight forward, bravo NTI.
I can't review every school in town, there are a few. But I'll say this. NTI takes 4 months to teach you the basics of HVAC/R. They don't waste your time with in person lecture, do it at home when its convenient for you. People live all over the valley and some drive a long way for class. Once a week come in and LAB, LAB, LAB, Hands-on, Hand-on, Hands-on. Great!!
NTI is not free, but, it is affordable. Its a good investment in your future in this industry. Most other HVAC/R schools are so expensive you'll be in debt for years. I am happy I made the switch to NTI. If your looking for a school give a SERIOUS look at NTI. I'm glad I did. Thanks Guys

Mark was amazing!! Patient and catered to our individual questions. I strongly recommend NTI!!

Excellent program, budget friendly, flexible and very informative. Everything is provided with a lot of hands on training. The whole staff is professional & friendly which makes it easier to communicate and ask questions. Mark Williams is an excellent instructor. He is very good at simplifying information and creates an excellent learning environment.

Enrolling to NTI was the best decision I have ever made, I would highly recommend it to everyone who wants to get in the HVAC trade. NTI has one of the best instructors in the country TY B, and he is really hands on and flexible. They are willing to work with anyone regardless of your work hours, Enrolling is easy and in 4 months NTI will give you a long life career. Thank you NTI, David and TY for my new career.

I have been on the hvac industry for over two years (In office) and wanted to get the proper training to become a certified technician. And I decided to go with NTI and I am glad I did. Their training is phenomenal and everyone is extremely professional. From David, Dexter, Mark and Casey. I highly recommend this school.

Certified HVAC/R Technician

I don’t even know where to start. 5 months ago or so I didn’t know what I wanted in life. I have a family and no real career. I have family who are in the industry of hvac and told me to look into it. I started looking at how much these guys make and was like that’s money I would love to make! Lol. So I found NTI and I went for a visit. Dexter made it feel like a home there and made me and my family feel very comfortable. Mark Williams and Casey are the most patient and coolest dudes you will meet. They will push you and make you work for it but they want what is best for you. They will spend every bit of there time with you as long as you want it and show that you want it. This school was the greatest decision of my life and I’ll never look back. Not only did I get a career out of this
I made great friends here in Phoenix. When I joined NTI I didn’t know if I made the right decision after week 4 I didn’t know maybe even after week 8 I didn’t know but I stand here today looking back and this is the greatest decision I could have ever made not only for myself but for my family. NTI, Mark, Casey, David and Dexter thank you guys so much I appreciate you guys. I recommend anyone that wants to join this industry to not even think twice and head to NTI they got you with everything you need.

They are always available for questions even after you have graduated. They give you information and expertise that can be taken into the real world. They provide youa great course on the fundamentals and do not set false expectations. Mark, Ty, and David all played a vital role in my success and an HVAC tech.

NTI is a fantastic school led by very knowledgeable instructors! Everyone was so helpful throughout the process and did everything to ensure everyone in the class succeeded. Just graduated last week and am excited to use the knowledge and experience I gained from NTI to start a successful career in the HVAC/R field! Huge thanks to everyone at NTI!

From day one the staff has been very helpful and knowledgeable. I had no experience in the Hvac trade and they’ve made my experience a lot easier and fun. To top it off, they helped me get a job only 2 days after graduation day!

It was a very great experience. I learned alot from Casey Katee and Mark Williams. They and instructional video really explained how HVAC works and be able to fix or find the what is wrong with the systems. Mark and Casey made a challenge in class room.
I thank you for the opportunity to attend your trade school....

It’s a great trade school. Great instructor Collin helps everyone no matter the experience they have going into the trade. I highly recommend to anyone wanting a career change.

Their plumbing class is great and will teach you the basics. Collins the plumbing instructor is a great teacher who will be patient in helping you understand plumbing.

I attended NTI and graduated. The teachers and staff were great. Very knowledgeable and helpful. I feel confident with my training to move forward in HVAC.

After successfully completing classes ana graduating at the National Technical Institute (NTI), I accomplished my goal of becoming a technical HVAC-R and holder of the EPA card at the same time which allows me to work anywhere in the United States of America! Thanks to Mark William, our instructor, made learning and practicing refrigeration cycle, ventilation, and electrical easy.

Started in July of 2020 but because of some life issues I’ve had to push my graduation off a little bit, and let me tell you guys David, Dextar, Mark, kasey everyone there is an amazing instructor anything you need answers they can help. I’d recommend this HVAC schooling to anyone who’s trying to get into the business, 15/10 stars guys thank you so much!!!!!!!

Thanks to everyone at NTI, it was exactly what I needed to further my understanding of beginning to intermediate HVAC issues and they are currently expanding their school to include other disciplines.

Thanks again Casey, Jared and Dexter for a great experience.

A fantastic beginning to a new career field. Great hands on experience and a quick transition into the working world. Couldn’t recommend this enough for someone looking to get into the Trades.

Thank you NTI team, it was an amazing experience 16 weeks Hvac experience, fast pace hands on training

I have been driving a Semi truck last 7 years and I changed my cureer to hvac and I couldn’t be happier to find nti, because I didn’t want to go 2 years hvac college.

Today we graduated and we have been given all necessary tools for free, and am ready to work now

Thanks Dexter, Mark, and Casey for all your good work ?

I'm the instructor here at NTI. We have an awesome program and a huge lab area just waiting for students to get their hand on experiences. Come join me and start a career that never stops.

Day 1 we were told that attending NTI is like building a bridge from both sides and meeting in the middle, one side being yourself the student and the other side NTI and the great employees they have, this is very true, all the knowledge is given to you and its up to you to utilize the instructors and staff which are always happy to help, from answering phone calls/ txts, to letting you stop by usually any time of the day any day and giving you extra help if needed. Highly Recommend National Technical Institute, Thank you.

I don’t know where to start but I have nothing but positive things to say about NTI and the people there. Very good people I am currently a HVAC Tech and am working on getting my experience I wouldn’t be here without NTI they are a great team. If you are looking for better opportunities ! GO TO NTI !

Listen, you will not find instructors that are more KIND, PROFESSIONAL and PATIENT. Dexter was extremely accommodating and WORKED WITH MY TRIBAL FINANCIAL DEPARTMENT to help me find the assistance I needed. They were EXCITED to HELP ME FIND MY NEW CAREER and you would be crazy to pass up the opportunities they provide.

I recommend ANY WOMAN LOOKING TO GET INTO THE PLUMBING INDUSTRY TO COME TO THIS SCHOOL!! Colin is an amazing instructor and one of the most humble human being that I know! The team here is AMAZING!!! Thank you so much NTI!!

Amazing crew here, they do all they can for you. We had 1 teacher that fell through and they had a replacement ready for us extremely quickly and we were still able to graduate on time

Overall Great time With Ralph Hunsley and everyone at NTI!!

The course details were definitely helpful the labs made everything make more sense. Mark, Casey, David, Dexter all very helpful. Definitely would recommend NTI.

By far the best choice I could’ve made. Everyone here is great at communication. Especially with Dexter , a call or text will never go unanswered. The whole staff is great and you’re gonna have everything you need to succeed.

Its been a pleasure taking classes with Mr Ralph,
He is a good instructor and good person and very knowledgeable.

Both Mark and Kacey were great instructors to me, and answered any and all kind of questions myself or the class had.

Excellent program, budget friendly, flexible and very informative. Mark is an excellent instructor. Hes very good at simplifying information and creates an excellent learning environment.

Great place to learn! Super flexible with only 1 day of school and easy to watch videos that you do throughout the week. If your a hands on and/or visual learner then this is perfect for you! Anybody thinking about going into this industry its a no brainer!

The schooling is really fun LOTS of on hands training and you only have to show up once a week for 4 months, my first day was excellent I highly recommend this school for anyone looking into the HVAC industry.

So nice to see NTI duplicate their successful school in Las Vegas here in Phoenix. Excited to see their accomplishments in helping new graduates secure entry level HVAC jobs in AZ.

I attended and graduated from this school and it was the best experience with a good set up for teaching and gives you a solid grasp on plumbing and how to be good at it as well
