Searching for a single statewide HVAC license in Indiana? There isn't one — the state licenses only plumbers, so HVAC licensing is handled by individual cities and counties. This guide covers the largest jurisdictions (Indianapolis and Allen County/Fort Wayne) and the one universal mandate everywhere: the federal EPA Section 608 certification.
Do You Need an HVAC License to Work in Indiana?
Indiana does not require a statewide HVAC contractor license; licensing is determined by individual cities, towns, and counties where you perform work. While the Indiana Professional Licensing Agency (PLA) oversees many trades, it does not issue licenses for HVAC contractors. This local control means requirements for experience, exams, insurance, and fees can vary significantly from one jurisdiction to the next.
The only universal requirement for any technician who maintains, services, repairs, or disposes of equipment that could release refrigerants into the atmosphere is the federal EPA Section 608 certification.
Navigating Indiana's Local HVAC Licensing Landscape
Because licensing is handled at the municipal level, your first step is to identify the specific requirements for every city or county where you plan to operate. Always contact the local building department or licensing board directly to get the most accurate and current information.
Key municipalities with specific HVAC licensing requirements include:
- Indianapolis (Marion County): Has a formal HVACR Contractor license with specific exam, bond, and insurance requirements.
- Allen County (Fort Wayne): Issues contractor licenses that may cover HVAC work, with its own set of rules and reciprocity options.
Other cities and towns will have their own distinct ordinances. Never assume the rules in one county apply to another.
How to Get an HVACR Contractor License in Indianapolis (Marion County)
The City of Indianapolis issues a specific HVACR (Heating, Ventilation, Air Conditioning, and Refrigeration) Contractor License through its Board of Heating and Cooling Examiners.
Eligibility Requirements
To qualify for an HVACR Contractor license in Indianapolis, you must meet the following criteria:
- Experience: at least five years of documented HVACR trade experience, or a combination of related education and practical work.
- Surety Bond: a $5,000 surety bond — typewritten, covering HVAC contracting, with the obligee "Consolidated City of Indianapolis and/or an Unknown Third Party" (continuous bonds are not accepted).
- Insurance: general liability of at least $500,000 (death/bodily injury per occurrence) and $100,000 (property damage per occurrence); workers' compensation is required if you have workers in Indianapolis/Marion County.
- Financial Responsibility: demonstrate financial responsibility as part of the application.
Step-by-Step Application Process for Indianapolis
- Verify Experience and Eligibility: Confirm you meet all prerequisites for experience and financial standing before starting the process.
- Obtain Insurance and Surety Bond: Secure the required $5,000 surety bond and certificates of insurance.
- Apply for and Pass the Examination:
- Exam Provider: the 2026 Indianapolis HVAC exam is administered by Prov, Inc. (an exam previously passed through Prometric may be accepted toward reciprocity).
- Exam Content & Fee: confirm the current content outline and exam fee directly with Prov.
- Submit License Application: After passing the exam, submit your complete application package — the official form, proof of experience, the original bond, insurance certificates, and your passing exam score report.
- Application Fees: the new-license-holder fee is prorated by application date — $377 (Jan 1–Jun 30, 2026), $283 (Jul 1–Dec 31, 2026), or $189 (Jan 1–Dec 31, 2027).
- Receive Your License: Once your application is approved, the board will issue your Indianapolis HVACR Contractor License.
How to Get an HVAC Contractor License in Allen County (Fort Wayne)
Allen County (which includes Fort Wayne) also licenses contractors, with a process that differs from Indianapolis. The county's exam-sponsorship application fee is $25, and the third-party testing facility sets the exam fees. For reciprocity, Allen County requires that your current license was obtained through a national exam via the International Code Council (ICC) or Prometric — it explicitly does not accept NASCLA, PSI, or ProV exams.
Confirm the experience, insurance, bonding, renewal, and exact classification with the Allen County Building Department — those specifics aren't detailed in the sources reviewed here.
EPA Section 608 Certification: The Statewide Requirement
All technicians in Indiana who handle refrigerants must hold an active EPA Section 608 Technician Certification. This is a federal requirement enforced by the U.S. Environmental Protection Agency and is the only credential mandated across the entire state for HVAC work.

- Types of Certification:
- Type I: For servicing small appliances.
- Type II: For servicing or disposing of high-pressure appliances.
- Type III: For servicing or disposing of low-pressure appliances.
- Universal: For servicing all types of equipment.

- Expiration: EPA Section 608 certifications do not expire.
Indiana HVAC License Reciprocity: Can You Transfer an Out-of-State License?
Indiana does not offer statewide HVAC license reciprocity because it does not issue a statewide license; however, some individual municipalities may grant reciprocity based on specific criteria. Out-of-state contractors must always meet the full local requirements for bonding, insurance, and application in the jurisdiction where they wish to work.
Indianapolis Reciprocity Criteria
The Indianapolis Board of Heating and Cooling Examiners may grant a reciprocal license if you meet these conditions:
- Your original license from another municipality is current and not suspended or revoked.
- The requirements to obtain your original license meet or exceed those of Indianapolis.
- Your original license was issued based on passing a standardized exam from Prometric, Inc. or a similar nationally recognized testing agency.
Allen County Reciprocity Criteria
Allen County may reciprocate a contractor license from another jurisdiction if:
- The original license was obtained by passing a national standardized exam, such as those from the International Code Council (ICC) or Prometric, Inc.
