Hvac Licensing in Idaho

Idaho HVAC License Verification

To legally perform Heating, Ventilation, and Air Conditioning (HVAC) work in Idaho in 2026, individuals and businesses must obtain appropriate licensing through the state's governing bodies. The Idaho Division of Occupational and Professional Licenses (DOPL), specifically its Heating, Ventilation and Air Conditioning (HVAC) Board, oversees HVAC licensing, while the Idaho Division of Building Safety (DBS) administers examinations and issues licenses. Idaho mandates licensing at every level: Apprentice, Journeyman, and Contractor.

An HVAC Apprentice must register before beginning any training and work under the direct supervision of a licensed journeyman or contractor. Requirements include being at least 18 years old (or 16 with approved programs) and employed by a licensed HVAC contractor. The initial apprentice registration fee is $10, with a $50 renewal fee every five years.

To qualify for an HVAC Journeyman license, applicants generally need four years (8,000 hours) of supervised work experience as a registered apprentice, coupled with 576 hours of classroom instruction. Alternatively, four years of HVAC education combined with supervised work under a qualified journeyman may be accepted. A Journeyman must pass a state-administered examination, which consists of 120 questions and has a four-hour time limit, requiring a 70% passing score. The application fee is $35, and the annual renewal is $75. The examination fee is $100.

An HVAC Contractor license requires at least 24 months (two years) of experience as a licensed journeyman. Contractors must also pass a state examination, which includes 110 questions, has a four-hour time limit, and requires a 70% passing score. The application fee is $35, and the annual renewal is $150. The examination fee is $100. There are currently no continuing education requirements for renewing Idaho HVAC journeyman or contractor licenses.

Insurance and Bonding Mandates

Idaho HVAC contractors must adhere to specific insurance and bonding requirements to operate legally. A crucial mandate is the provision of a $2,000 compliance bond, which safeguards the public in case the contractor fails to adhere to certification regulations.

All Idaho HVAC businesses are required to carry General Liability Insurance, with a minimum coverage limit of $300,000. Furthermore, if a contractor employs staff, Workers' Compensation Insurance is mandatory to cover work-related injuries or illnesses. Commercial Auto Insurance is also essential for businesses utilizing vehicles for work-related activities. These insurance coverages provide vital protection against potential risks and liabilities inherent in the HVAC industry.

Permitting and Local Regulations

HVAC work in Idaho typically necessitates permits and inspections to ensure compliance with established local and state building codes, as well as manufacturer specifications. Idaho largely adopts the 2021 International Energy Conservation Code (IECC) for energy efficiency standards.

Specific permitting requirements often include Manual J load calculations (though local departments should be consulted for definitive requirements), a mandatory REScheck Energy Analysis, documentation of equipment efficiency (such as SEER/HSPF ratings and ENERGY STAR certification), and Manual D duct design calculations. While some rural areas may have fewer permit requirements, it is critical for contractors to verify specific regulations with the city or municipality where the work will be performed. Licensed HVAC installers are generally exempt from the broader Idaho Contractor Registration Act, unless their scope of work extends beyond HVAC services.
