How Idaho licenses HVAC work
HVAC contractors are licensed by the state.
Who licenses: Idaho Division of Occupational and Professional Licenses (DOPL), Heating, Ventilation and Air Conditioning (HVAC) Board
License types: HVAC Contractor, HVAC Journeyman, HVAC Apprentice, Specialty Contractor, Specialty Journeyman, Specialty Apprentice, Limited Heating Specialty (apprentice, journeyman, contractor).
Companies: Idaho Code Title 54, Chapter 50 (installation of heating, ventilation and air conditioning systems) sets up certificates of competency for HVAC contractors, journeymen, apprentices and specialty classes, issued by DOPL under IDAPA 24.39.70. Section 54-5009 defines an HVAC contractor as a business engaged in installing, maintaining or repairing heating, ventilation or air conditioning appliances, and section 54-5007 requires contractors and the other classes to be bonded. Section 54-5002 exempts, among others, an owner or contract purchaser who works on their own single or duplex family dwelling, farm buildings outside city limits, and employers' own premises where the employer regularly employs HVAC journeymen. We did not find a single sentence in the statute text we read that states the licensing mandate in plain words, so the scope is taken from the definitions and exceptions.
Local rules: Under Idaho Code 54-5015 a city or county may not require additional HVAC certification, registration or fees for people holding the state certificate, but the same section says cities and counties may still impose stricter public safety rules. We did not look at individual city permit rules such as Boise.
Check a license: edopl.idaho.gov
Search the company on the DOPL license search and confirm it holds an active HVAC Contractor (or relevant specialty contractor) certificate and that the person doing the work is a licensed journeyman or a registered apprentice.
Federal rule: in every state, technicians who handle refrigerant must hold EPA Section 608 certification, whatever the state or city requires.

Before you hire
Ask for the license number and check it on the official lookup where one exists. Ask for proof of insurance and a written, itemized estimate, and ask who pulls the permit if the job needs one – a new furnace, heat pump or air conditioner usually does.
