Before you hire
Checking an HVAC company in the Indianapolis area
HVAC licenses in Indiana
There is no statewide HVAC contractor license that we could find; cities or counties license HVAC work.
Local rules: The Indiana Professional Licensing Agency's list of licensed professions includes plumbing but shows no HVAC, heating, air conditioning, refrigeration or mechanical contractor category, so we could not find a statewide HVAC contractor license and we believe any licensing is set by individual cities and counties. We could not read the Indianapolis, Evansville or Fort Wayne licensing pages (the city sites returned no usable content or blocked access), so we could not confirm any specific local HVAC license, its name, or its requirements.
Call your city or county building department and ask whether HVAC contractors must be licensed or registered locally and whether a permit is required, then ask the contractor for that local license or registration number and confirm it with the department.
Federal rule: in every state, technicians who handle refrigerant must hold EPA Section 608 certification, whatever the state or city requires.
We could not confirm every detail from Indiana’s own sources, so treat this as a starting point and check with the agency.
Sources: in.gov. Checked October 2026 from official sources. This is not legal advice.
Questions to ask
Ask every company the same questions: license number, insurance, EPA refrigerant certification, a written itemized estimate, a load calculation for new equipment, after-hours rates, who pulls the permit, and the warranty. All eight questions.
Seasonal care
Getting through a Indianapolis winter
Heating season is the long one in Indianapolis, so the furnace, boiler or heat pump does most of the work. Start with these before the first cold snap – and keep carbon monoxide alarms working.
