Idaho HVAC License Lookup
Where to Search
Idaho's Division of Occupational and Professional Licenses (DOPL) maintains a public license search portal through its OASIS system. Anyone can verify an HVAC license — you don't need an account or login credentials.
The search is available through DOPL's OASIS portal at edopl.idaho.gov. The portal covers all trades regulated by DOPL, including HVAC, electrical, plumbing, and general contracting.
What You Can Verify
A license lookup returns several pieces of information that matter for different situations:
License Status: The most basic check. An "Active" status means the credential is current and the holder is legally authorized to perform work within their license scope. "Expired" means the license lapsed — work performed by someone with an expired license violates state law. "Revoked" or "Suspended" indicates disciplinary action by the HVAC Board.
License Type and Classification: Confirms whether the person holds an unrestricted journeyman or contractor license, or one of the four specialty classifications (Hearth, Waste Oil, Fuel Gas Piping, or LP Gas Limited Heating). This matters because specialty licensees have strict technical scope limits — a Hearth specialty journeyman cannot perform unrestricted HVAC installations.
Original Issue Date: This is critical for one specific purpose. To qualify as a Qualifying Agent for a contractor license, a journeyman must have at least 24 months (or 4,000 hours) of qualifying experience. The original issue date on the public record helps verify this threshold for an Idaho journeyman; DOPL may also recognize documented experience from an equivalent jurisdiction.
License Number: Used for permit applications, project documentation, and formal complaints.
When You Need a License Lookup
Hiring a contractor: Before engaging an HVAC contractor for a project, verify their license is active and that they hold the correct classification for your work. An unrestricted contractor can handle any HVAC project. A specialty licensee can only perform work within their narrow scope.
Hiring employees: If you're an HVAC contractor hiring journeymen, verify each candidate's license status before they start work. Any hours your apprentices log under a journeyman whose license was inactive are permanently invalid — which means your apprentices lose those hours.
Subcontractor verification: General contractors and project managers should verify HVAC subcontractor licenses before awarding contracts and check the local building department's permit requirements.
Designating a Qualifying Agent: If you're forming a business entity and need to designate a Qualifying Agent, the license search confirms an Idaho journeyman's status and original issue date. Use that date to assess the 24-month/4,000-hour threshold, while remembering that DOPL may also recognize documented experience from an equivalent jurisdiction.

Work Verification Is Different
The public license lookup tells you whether someone is currently licensed. It does not show their work history, OJT hours, or experience documentation. Those records are submitted directly to DOPL through notarized Work Verification Forms and are part of the applicant's confidential file.
If you're an apprentice or journeyman who needs to verify your own work history for an application, you'll work with DOPL's licensing staff directly — the public portal won't show that information.
Verifying Contractor Compliance Beyond the License
An active HVAC license alone doesn't mean a contractor is fully compliant. Contractors also need an active $2,000 compliance bond on file with DOPL, and most municipal building departments require proof of general liability insurance to pull permits. The license lookup confirms the credential but not these financial protections.
