Step-by-Step Process

1
Ohio has no HVAC reciprocity agreement with California. OCILB's published HVAC agreements are with Alabama, Kentucky, Louisiana, Mississippi, South Carolina, Tennessee, and West Virginia; no California agreement file exists. Under ORC 4740.08, licensing without examination requires such a written agreement.
2
Ohio's state HVAC license is a contractor license for commercial work, issued by the Ohio Construction Industry Licensing Board (OCILB) and tied to a 'contracting company' — the same license level as California's C-20 (Warm-Air Heating, Ventilating and Air-Conditioning) contractor license.
3
Instead of reciprocity, OCILB's Out-of-State Examination Application offers a route for holders of an out-of-state trades contractor license 'substantially similar' to the Ohio license (ORC Chapter 4796). It replaces Ohio's usual five-years-as-a-tradesperson requirement, but the Ohio examination is still required.
4
needs_review: whether a California C-20 license is 'substantially similar' to Ohio's HVAC contractor license is OCILB's case-by-case judgment — Ohio law does not define the standard.
5
needs_review: ORC 4796.01 defines an out-of-state occupational license as one issued 'to an individual.' CSLB issues contractor licenses to the business (a sole owner, or a company qualified by an individual), so whether a C-20 held by a corporation or LLC — rather than a sole owner — fits that definition is not settled by the text.
6
Document: the California license held for at least 5 years (e.g., a letter of good standing); at least five building permits issued under that license; at least one tax return showing income earned under it (plus one W-2 if not an owner); and that your contracting company is registered in Ohio as a foreign corporation or foreign LLC with a designated in-state agent.
7
Maintain contractor's liability insurance of at least $500,000 in a single contracting company's name.
8
Pay the $25 application fee. Once approved (approval is valid for one year), complete BCI and FBI background checks, then schedule the PSI computer-based exam; PSI's exam fee is not published in the application.
9
After passing both sections, send the exam results, a $25 license fee, and a certificate of liability insurance; the license and insurance must be assigned to a contracting company.

Note: Ohio side confirmed 2026-09-30 by direct pdftotext extraction of OCILB's Out-of-State Examination Application (form dated 9/2025; server Last-Modified 2026-02-03), downloaded from dam.assets.ohio.gov. Item 8 covers 'an individual who holds an out-of-state trades contractors license, as defined in section 4796.01 ORC, that is substantially similar to the license for which the individual is applying'; the form states OCILB 'issues state licenses to Electrical, HVAC, Refrigeration, Plumbing, and Hydronics Contractors who perform commercial work'; fees are $25 application and $25 license. Reciprocity: OCILB's per-state agreement PDFs were fetched and extracted — HVAC appears in the Alabama, Kentucky, Louisiana, Mississippi, South Carolina, Tennessee, and West Virginia agreements; a California agreement file returns 404. California side: CSLB's Reciprocity Requirements page lists Arizona, Louisiana, Mississippi, Nevada, and North Carolina — not Ohio. C-20 is a CSLB contractor classification (16 CCR Division 8, Article 3 (CSLB cites the article, not a section number, on its classification page)). PROVENANCE: the ORC texts are official text from codes.ohio.gov, retrieved and extracted by a helper tool (WebFetch) on the user's side, not read directly by Claude Code; codes.ohio.gov refused connections from this environment and every com.ohio.gov page returned 404 here. ORC 4740.08 (summarized, not verbatim): licensing without examination requires a written reciprocity agreement and 'substantially equal' requirements. ORC 4796.01 (verbatim excerpt as provided): 'out-of-state occupational license' means 'a license, certificate, registration, permit, card, or other authority that is issued or conferred by one of the uniformed services or the government of another state to an individual by which the individual has or claims the privilege to engage in a profession, occupation, or occupational activity'; no general definition of 'substantially similar' appears. Note that OCILB's form refers to an 'out-of-state trades contractors license, as defined in section 4796.01 ORC', a term that excerpt does not itself define. Visual verification is recommended when access allows. Ohio's state license covers commercial work; how residential hvac work is regulated in Ohio was not confirmed from an official source here. feeUsd is the $25 application fee only; the $25 license fee and PSI's exam fee are separate.
