I had an incredible experience with Leonardi HVAC School! From the moment I enrolled, I could tell that they truly care about their students’ success. The instructors are incredibly knowledgeable and approachable, always ready to help with any questions. The hands-on training was excellent, and I really appreciated how they emphasized real-world applications alongside theory. The curriculum was comprehensive, and I felt fully prepared to enter the HVAC field. The school’s commitment to providing a top-tier education shows, and I’m grateful for the skills and confidence I gained. Highly recommend Leonardi HVAC School to anyone looking to start or advance in their HVAC career

After spending 4 months in one of the local large “Tech Schools” 3 days a weeks for 8hrs/day and learning nothing from an incompetent instructor I found Leonardi Training Center. After speaking with Roseanna and being able to get in due to a cancellation to talking with my Instructor 1 on 1 about my previous experience he assured me they were different!

I paid my tuition and started the classes. In 10 minutes I learned more than in 4 months. Mr Leonardi you should be proud of the program you have created and have left it in amazing hands with Mike. Mike has consistently made it a point to follow up with me to make sure I am picking things up and continuously learning and grasping the material.

I was so impressed with the first class I was able to also register my nephew in the same class and immediately paid for his tuition as well.

Further I still have contact with several of my previous classmates that are unable to even find employment in the industry due to lack of knowledge even though they “graduated” from the big name technical college.

Leonardi specializes in one thing only and that is HVAC and they have a program that is second to none.

There is a reason the wait list is long. This is not a government handout school. The people enrolled here are dedicated to their professional advancement.

To the few that know…”it’s not what’s different it’s what’s the same”…. Except the HVAC educational program at Leonardi it is definitely different.

This school is sick only here have I gotten a real education while other "schools" just tell u about their products and how good they are but that's it. Here at Leonardo they explain in full detail on how everything works and why it's done this way and really go into depth on how to troubleshoot any problem possible if your thinking of becoming an HVAC tech coming to this school will be the best idea for your career possible

Leonardi HVAC Training offers great value, whether you're just starting out or looking to upgrade your skills. Their commitment to providing quality education is evident, and I highly recommend it to anyone serious about a career in HVAC.

There is a reason this school has a wait to get in. Truly the best HVAC school in Colorado. I have never worked in the industry before, I figured it would be better to learn about what I’m doing first before trying to get a job. This school has absolutely prepared me for going into the field. I’m not even half way thru and I’m 100 times more confident than when I started! Mike is an amazing teacher, he is fun, dedicated, and experienced. If your looking to go into the industry, advance upon your current skills, or just learn about the amazing technology that keeps us comfortable. Leonardi is for you.

Before enrolling at Leonardi, I had 0 knowledge about HVAC and minimal understanding of electricity or how to use a multimeter. Now, I can confidently walk through a schematic and wiring diagram, understanding both the low and high voltage sides of a system with a solid base of fundamentals that i will carry with me for the rest of my life .

The hands on approach at Leonardi has been invaluable, combining theoretical knowledge with real world application. Mike’s passion for the subject is infectious, and he has lit a fire of passion within me for HVAC.

I couldn’t recommend Leonardi enough. The knowledge and confidence I’ve gained in such a short time are remarkable.
Mike’s effective teaching methods have made learning accessible and enjoyable.

As someone who wanted a career change at 37 years old, I couldn't be happier with my choice to register for HVAC classes with Leonardi. I came into this with zero HVAC knowledge. Signing up for the class is a little stressful - just call, and once you are able to leave a voicemail, they will call you back without any issues.

The class itself is very practical - there is some lecturing but it is quickly followed by labs for hands-on experience. All topics are covered at least twice - helps to reinforce information without having to do homework between classes. Some of my classmates said they wish they would have had the class before they started working because it is so helpful. Looking forward to getting to see for myself! I wouldn't hesitate to recommend this class for anyone either looking to get into HVAC, those early in their careers, or those wanting to understand why they do what they do.

I have been an HVAC installer for 6 years. Before I went to this school, I thought I knew everything. Thanks to Don Leonardi, I realized that I didn't know anything correctly. I am truly grateful to this school, to Don Leonardi and his wife Diane, because they form the perfect team to teach, inspire, and transform technicians to be more successful. I miss these classes, I miss how Don Leonardi made the class a play and very easy to understand where all I wanted to do was applaud him after each of these classes 👏👏👏
When I thought I didn't have time and these classes were very difficult due to tiredness after work I was about to give up on classes but Diane called me and gave me very motivating words about why I should continue, now I really appreciate it 🙏 I have my NATE certifications, EPA certification these certificates make me work more comfortable helping clients feel confident that a professional is installing their system in the appropriate way to take advantage of its best functionality and, above all, in the safest way for myself and my clients.
Thank you very much Leonardi and Diane! 🙏
