Best HVAC Schools in Colorado: Air Conditioning Training, License & Certification

Becoming an HVAC technician is one of the most rewarding and in-demand jobs across the country right now. It is expected to stay this way for the next decade, too. If you have thought about working in the HVAC industry, now is the time.

This article will examine the best HVAC schools in Colorado to help get you started off on the right foot towards your full HVAC certification. I will also cover things to look for when deciding on a school and how to become a fully certified HVAC tech in the great state of Colorado.

hvac apprenticeOn a state level, Colorado does not have any special technician requirements. However, you must be aware that the EPA regulates who can work on refrigerated systems. All HVAC technicians are required, by law, to obtain the EPA 608 certification (Type I, II, III, or Universal).

If you are looking to gain experience and start your own HVAC company, you will need to hold a Colorado contractor’s license. This is also a different beast as the state itself does not have or hold specific requirements.

Instead, these are handled on a municipality level. What grants you a contractor’s license in Denver or Colorado Springs may differ in Centennial, Lakewood, or Westminster.

In general, though, you will need to pass an ICC exam (generally the F13 – Class C). These exams are the first step for a contractor’s license. From there, each city will have it’s own rules, regulations, and exams.

Also, important to note, Colorado is one of the few states that doesn’t designate HVAC as it’s own profession. Instead, you will need to contract as a Master Plumber or Master (or Journeyman) Electrician with HVAC capabilities.

How To Become An HVAC Technician

The process of becoming an HVAC technician in Colorado is relatively simple. While the hours may be long and exams difficult, the timeline is straightforward.

First, you need to obtain your high school diploma or GED. This will be the first step in every state, but it needs to be mentioned. From there, you have a few options. The best method, though, is outlined below.

  • Attend an accredited HVAC school or course through a trade school, college, or university.
  • Gain acceptance into an apprenticeship program or internship in HVAC.
  • Obtain your EPA 608 certification and take any certification exams deemed needed (NATE, for example).
  • As a fully certified HVAC tech with experience, begin looking for that ideal, full-time job.

Quick Guide in Choosing Your HVAC School

Below you will find a brief overview of several factors worthy of consideration. Each school you are thinking about should fit your specific needs based on the following parameters.


Where the school is, physically, in proximity to your home or work is essential. You want to be able to make it to the classes on time and on a regular basis. Keeping in mind things like schedules, traffic and unexpected accidents, the closer the school is to you, the better it can be.

However, don’t let this be the only factor for determining the school you attend. You may find a better match for your specific needs a little further away.

Accredited School

School accreditation is important, as well. This is the process the school goes through to prove to the governing bodies they offer a full, robust, and regulated education system. While accreditation only means they meet the minimum standards set by these governing bodies, it is a clear indicator they are a quality school.

Offers Quality Education

The overall quality of the education is the most important aspect. The only way to know for sure is to either attend the school and hope for the best, or, better yet, visit the school.

When you visit the campus, you can talk to current students and instructors to find out their thoughts and feelings. You will also get a better feel for the campus and atmosphere. Figuring out what books the school uses, or what HVAC software they have for use is also an important factor in deciding the quality of their system.

Offers Hands-on Training

Hands-on training is crucial to becoming an HVAC technician. Without the lab work, you can only see how a tool works or check diagrams of operational systems. Getting your hands on the tools and understanding the equipment is the only way to learn how everything works together.

Many certifications require a minimum amount of lab hours. Ensure your school offers a healthy dose of lab work, which should equal or exceed the number of classroom hours.

Connects you to an Apprenticeship/Internship Program

Many schools also offer post-graduate programs, and it is highly recommended that you find such a school. Not only will these programs help you apply for posted jobs, but they can also help you get into a quality apprenticeship program.

Many of the steps required to gain acceptance in these programs are challenging to obtain or meet on your own. The assistance of the school and personnel that know how these systems work is only advantageous for you.

Offers Customer Service Skills Training

Customer service skills training is also something you want to look for. A lot of your time as a technician in the field will be spent with customers. Knowing how to communicate with them effectively is a big part of your job, and the training should also be a good portion of the school’s curriculum.

Most trade schools in Colorado will have tuition fees that range from $3,000 to $8,000. The longer the course, the more lab hours and higher quality of the education, the more you will pay.

Likewise, for a college or university, you will pay more. Generally, you will attend these schools when you are after an HVAC degree. Some colleges do offer diploma and certification courses, along with degree-granting courses, but the cost is about the same.

For colleges and universities, you will pay by the credit-hour. Most courses will fall between 40 and 120 credit hours, depending on the type of course (certification, associate’s, or bachelor’s degrees). You can expect to pay about $5,000 to $8,000 per year or $20,000 to $40,000 for the two degrees. Don’t forget to look into financial aid to help with these costs, too.

People Also Ask (FAQ)

There are two degrees you can obtain in the HVAC field. The associate’s degree is a standard 2-year degree which can be completed in 18 to 24 months.
