Vibrant Networking Community

Indiana is the home to a vibrant HVAC community. Several organizations work hard to facilitate their workers in their professional growth and activities. For instance, a non-profit organization called The Indiana HVAC Association collaborates with workers and contractors to provide top-quality expertise and customer service throughout Indiana.

Growing Economy

The economy of Indiana is growing by leaps and bounds. The HVAC industry plays a huge role in its development. The main economic sectors rely on HVAC systems for maintaining an adequate climate to facilitate production. Industries like auto manufacturing, life sciences, transportation, information technology, and research cannot function properly without an efficient HVAC installation in place.

Apprenticeship Programs

In Indiana, you don’t necessarily need vocational training to start your career. Many union and non-union sponsors offer apprenticeship programs to train aspirants for becoming HVAC professionals. These programs last for three to five years and completely train applicants about the ins and out of the industry. After completing this apprenticeship, you can go on to apply for your contractor license.

Licensing Requirements

Indiana does not require HVAC technicians or contractors to have special licensing on certification in the field. However, many local governments do have requirements. Be sure to consult with your county or city before undertaking any projects.

Indianapolis, for example, requires licensing for HVAC contractors. If you’ve passed a Prometric exam, you may qualify for a waiver of the city’s licensing process. There are additional requirements and it is at the discretion of the Board of Heating and Cooling Examiners.

The city and all of Marion County, where it’s located, offer five classes of licenses:

  • Air Conditioning “A” – this is an unrestricted license
  • Air Conditioning “B” – allows work on cooling units up to 25 tons, or heating units up to 500,000 BTUs, and boiler pressures not above 15 psig steam and 30 psig water
  • Air Conditioning “D” – allows work on units up to 5 tons of cooling and 300,000 BTUs heating
  • Refrigeration
  • High-Pressure Steam

Detailed information for the Indianapolis/Marion County HVAC Contractor license is on the county’s webpage.

EPA Certification

If you will be working with refrigerants, you still have to have federal certification under EPA Section 608. There are 4 classes, depending on the type of unit you’ll be working with.

The fourth class actually covers all classes. This is required anywhere in the United States. If you work especially with refrigeration units or handle refrigerants as part of other systems, please be sure to check out the requirements and process for Section 608.

HVAC Exam Preparation in Indiana

As we mentioned earlier, there is no state-approved HVAC contractor license issued by the State of Indiana. Different cities and counties have their own requirements and protocol for HVAC professionals who want to start their own business as contractors, and all of them require you to pass an exam. Your preparation for the licensing exam starts right from the beginning of your career.

In Indiana, you have two learning pathways to become an HVAC professional. You can enroll in a vocational program of an accredited institution or apply for an apprenticeship. Many believe that an apprenticeship is better because you get on-the-job experience as well as the necessary education to join the force as an entry-level worker.

Once you have completed the credits as an apprentice, you can take an exam to promote the journeyman’s level. After working as a journeyman for at least four years, you are allowed to take the master-level exam. 

Various cities and counties of Indiana require you to attain the master level before applying for your contractor license. So if you opt for the apprenticeship program, it will leave behind the necessary paper trail that proves your experience on the field. And frankly, this much hands-on experience in the field can prepare anyone for taking their final exam.
