Does Indiana License HVAC Contractors? What the Business Needs Instead

Only locally.

Indiana has no statewide HVAC technician or HVAC contractor license: the Indiana Professional Licensing Agency's list of licensed professions includes Plumbing but no HVAC, heating, mechanical or refrigeration entry.

Indianapolis' own board document puts it directly: licensing is at the discretion of the local municipality.

So the requirements that bind your business are the ones the local municipality where you work sets, at its own discretion.

Plumbing is the neighboring trade's different story — Indiana licenses plumbing contractors statewide through the Indiana Plumbing Commission — but there is no HVAC equivalent.

The individual technician side of this question is its own topic, covered on the individual Indiana HVAC license page.

No state agency issues an HVAC contractor license in Indiana.

The local system the research captured is Indianapolis: the Board of Heating and Cooling Examiners, in the Department of Business & Neighborhood Services, issues heating and cooling contractor licenses in five types — Air Conditioning 'A' (unrestricted), 'B' (25 tons cooling / 500,000 BTU heating, boiler pressures not exceeding 15 psig steam and 30 psig water), 'D' (5 tons cooling / 300,000 BTU heating), Refrigeration, and High Pressure Steam.

The board meets the second Monday of each month, and applicants must file their packets at least 10 business days before a meeting and appear before the board.

Choose the class that matches the equipment your business installs, and confirm the class list and scopes with the board before you bid.

In Indiana this question is municipal, because with no state license there is no state qualifier rule.

In Indianapolis, the license holder is the load-bearing role for your whole crew: an unlicensed worker employed by a licensed heating and cooling contractor may do that work under the contractor's direction and control, limited to the scope of the contractor's license type, and may not contract on their own.

The one experience rule on record applies to reciprocal applicants: they must document at least five years of HVACR trade experience, or a mix of industry education and work, verified by current and former employers on employer letterhead.

Our research did not capture what experience the board requires from exam-route applicants, so ask the board before you staff the role.

When you do need to find or keep that person, HVACHires' qualifying agent guide covers how businesses recruit and retain a qualifier.

For an Indianapolis heating and cooling license, the board's 2025 policies set the exam pass mark at 70%, with a one-year wait to retest after a second failure.

Alongside the license exam, the board ties EPA Section 608 certification to the license: Universal for Air Conditioning 'A' and Refrigeration, Type I and II for 'B' and 'D', and none for High Pressure Steam — that is the federal refrigerant-handling certification, not an Indiana credential.

Our research does not record a separate business-and-law exam for the license, and it does not describe what the trade exam covers, so confirm the exam lineup and content with the board before you book study time.

For an Indianapolis heating and cooling contractor, bonding and insurance come after the board vote: once the Board of Heating and Cooling Examiners approves you, the contractor must file proof of a surety bond, general liability insurance and workers' compensation coverage, with fees and the application, to the licensing section before the license issues.

The dollar amounts were not verified in our research, and our research found no state bond or insurance rule for HVAC contractors to fall back on — there is no state license for one to attach to.

Get the current amounts from the board or the licensing section before you price them into your bids.

HVACHires' separate guide to contractor license bonds and insurance explains how these instruments work where a city does require them.

There is no state fee, renewal cycle or continuing-education rule to report — none exists because there is no state license to carry one.

The local amounts were not verified in our research either: the sources we read for Indianapolis did not include its license fees, renewal fees or renewal period, and other cities' fee schedules were not researched at all.

A fee advertised as an Indiana HVAC contractor license fee cannot be a statewide fee, because there is no such state license.

Ask the city or county where you will work for its current fee and renewal schedule before you budget.

There is no state HVAC reciprocity in Indiana: a state can only reciprocate a license it issues, and Indiana issues none.

What exists is municipal.

Indianapolis grants reciprocal heating and cooling licenses only for a current license from another municipality or agency, and only when that license was earned on a Prometric or Prov exam the board verifies as equivalent to its own, with a minimum score of 70%.

Reciprocal applicants also document at least five years of HVACR trade experience, or a mix of industry education and work.

The route is written narrowly, so ask the board before you count on an out-of-state or out-of-town license.

In Indiana this failure mode has no state version: with no state license and no state qualifier, no departure can strip a state credential from your business.

The exposure is local instead.

An Indianapolis worker without their own license may do heating and cooling work only as an employee of a licensed contractor, under that contractor's direction and control, so the license holder's departure raises exactly the question this section is about: who directs and controls the work, and how fast must a replacement be in place?

What the board requires in that situation — a replacement window, a provisional license, a notice requirement — was not captured in our research.

Ask the Board of Heating and Cooling Examiners before your business depends on one person's license.

Indianapolis is the local system the research captured.

Its Department of Business & Neighborhood Services licenses heating and cooling contractors through the Board of Heating and Cooling Examiners, in five types: unrestricted Air Conditioning 'A', scoped 'B' and 'D' classes, Refrigeration and High Pressure Steam.

Licenses are examined at a 70% pass mark, EPA Section 608 certification is matched to the class, and proof of a surety bond, general liability insurance and workers' compensation coverage is filed before the license issues.

An unlicensed employee of a licensed contractor works under that contractor's direction and control, limited to its license scope.

The rest of Indiana was not researched: our research did not capture rules for Fort Wayne, Evansville, South Bend or any other municipality, so treat Indianapolis as one city's example and confirm with the building or licensing department where the work will be done.
