For HVAC, Indiana leaves licensing to local municipalities. In the Consolidated City of Indianapolis, Code § 875-301 requires an HVAC license to install, replace, service, or repair heating, cooling, and refrigeration equipment — and even certain exhaust-hood ductwork. Applicants pass the Board of Heating and Cooling Examiners exam (or apply by reciprocity), then license both the business and the individual craft license holder.
The federal layer never goes away: technicians who maintain, service, repair, or dispose of equipment that could release refrigerants must hold EPA Section 608 certification (Core plus Type I, II, III, or Universal).
The state sets the license floor; the county or city permit office controls filing, inspections, and local rules wherever the job site sits.
Indiana has no statewide contractor license outside plumbing, so the license question is answered where the work is: the Consolidated City of Indianapolis (BNS, Revised Code Chapter 875) runs a real licensing program with bonds and insurance; Allen County's Building Department licenses building, residential, home-improvement, and sub-contractors for the Fort Wayne area; and cities like Lafayette and counties like Monroe run their own electrical boards. The Attorney General's own guidance is that licensing requirements vary from community to community.
