Essential Certifications and Licenses

Formal training is just one piece of the puzzle. To work legally and prove your expertise, you’ll need specific certifications and, depending on your state, a license.

EPA 608 Certification

The EPA 608 certification is a mandatory federal credential for any technician who buys, handles, or works with refrigerants. Administered under Section 608 of the Clean Air Act, this certification is designed to protect the environment from ozone depleting substances.

There are four types of certification, and most technicians aim for Universal, which covers all equipment types:

• Type I: For small appliances.

• Type II: For high pressure systems.

• Type III: For low pressure systems.

• Universal: For all system types.

You must pass an EPA approved proctored exam to get certified. The good news is that this certification never expires. Platforms like SkillCat are EPA approved to administer the test online, offering a convenient way to earn this essential credential.

NATE Certification

NATE (North American Technician Excellence) certification is the industry’s gold standard for validating a technician’s knowledge and skills. While it’s a voluntary certification, many employers prefer or even require it because it demonstrates a high level of expertise.

To become NATE certified, you must pass a core exam and at least one specialty exam in an area like air conditioning, gas heating, or heat pumps. Because technology is always changing, NATE certification must be renewed every two years by completing 16 hours of continuing education, ensuring your skills stay sharp.

Mechanical Contractor License (Michigan Example)

Licensing requirements vary by state and sometimes by city. In Michigan, for example, there is no journeyman license. Instead, anyone who wants to operate an HVAC business must obtain a Mechanical Contractor License from the state.

To qualify, you need at least three years (or 6,000 hours) of relevant work experience. After your experience is verified, you must pass a state exam covering codes, safety, and installation practices for your chosen specialty. This license is the key to working independently and pulling permits for HVAC jobs in the state.

Inside the Curriculum: What You’ll Learn in HVAC Training

A quality hvac vocational training program provides a well rounded education covering the key systems and skills you’ll use every day. Here’s a look at what you can expect to learn.
