Indiana HVAC License: Everything You Need to Know

Homeowners and businesses depend on HVAC services. If you want to become an HVAC technician or even start your own business, you need to have an Indiana HVAC license. In this guide, you will learn about the education and job requirements for getting your license.

Do You Need a License in Indiana to Become an HVAC Technician?

Yes, you need an Indiana HVAC license. All technicians must have a Section 608 Certification to work on appliances that use refrigerants, including central air conditioning units.

What are the Different Types of HVAC Licenses?

Technicians working in Indianapolis and in Marion County must hold at least one of the following licenses issued by county officials:

  • Unrestricted Air Conditioning License A

  • Air Conditioning B (to work on cooling units up to 25 tons and boilers up to 15 psig steam and 30 psig water)

  • Air Conditioning D (to work on cooling units up to five tons and heating units as large as 300,000 BTUs)

  • Refrigeration

  • High-pressure steam

In addition to an Indiana HVAC license, technicians must obtain certifications from one of the three following organizations: The Environmental Protection Agency (EPA), the North American Technical Excellence (NATE), and the American Society of Heating, Refrigeration and Air Conditioning Engineering (ASHRAE). Some schools also provide certification through HVAC Excellence.

EPA Certifications

Section 608 of the Clean Air Act requires anyone who wants to work with refrigerants to obtain EPA certification. The base certification, Type I, to service small appliances. Type II covers high to very-high pressure appliances; Type II covers low-pressure appliances; and Universal covers Types I, II, and III. You also must pass the core competencies, such as Section 608 regulations, the Montreal Protocol, and the Clean Air Act. Renewal is not required.

Apprentice, Journeyman and Master Licenses

Professionals will not find a formal Indiana HVAC license system for apprentice, journeyman, and master designations in the state. Limited apprenticeships are available through union and non-union sponsors. Completing an apprenticeship takes about four years, and then you’ll pass an exam to attain journeyman status.

An associate’s degree in Applied Science or a certificate in HVAC through a college or university program also can qualify you for an apprenticeship program. Working as an apprentice is the first step to becoming a journeyman and eventually a master HVAC tradesman. Some Indiana municipalities require professionals to become a master tradesman to start their own contracting business.

Non-union apprenticeships are available through some employers. Trade organizations such as the Indiana/Kentucky Chapter of the Associated Builder and Contractors and the Indiana Plumbing-Heating-Cooling Contractors Association also offer apprenticeships. Contact local pipefitters and sheet metal trade unions for their apprenticeship programs.

NATE and ASHRAE Certifications

NATE Certifications are more comprehensive and go beyond cooling to incorporate heating applications and more specialized applications. The four different types of NATE certifications include:

  • Ready-to-Work Certificate

  • HVAC Support Technician

  • Core and Specialty Tests

  • Senior Level Efficiency Analyst

ASHRAE certifications target designers and engineers of climate control systems. For instance, a Certified HVAC Designer focuses on the design and layout of residential and commercial systems, including sizing and load calculations.

Entry-level technicians start at $25,770 per year. Middle-level annual pay is $40,930, while master technicians earn $71,000.

Benefits of Getting an HVAC License

Indiana has one of the fastest-growing markets for HVAC professionals. Obtaining as many licenses or certifications as possible will increase your earning potential. You can start your own business, too. A license demonstrates to clients that you have the education and experience to properly service their climate control units.

How Much Does It Cost to Get an HVAC License in Indiana?

Because HVAC technicians must obtain an EPA 608 Basic Certification, the minimum cost is $24.95 for the initial test and $5.95 for each additional attempt. If you get certification through a school, that cost may be included. For a formal apprenticeship program through the Indiana Plumbing-Heating-Cooling Contractors Association, the cost ranges from $1,200 to $1,425, depending on the program and location.
