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.
