Mississippi to Ohio: master HVAC technician license reciprocity

Ohio has no license called 'master HVAC'; its top person-held HVAC credential is the statewide HVAC Contractor license (with a separate Refrigeration Contractor license for refrigeration work) issued by the Ohio Construction Industry Licensing Board (OCILB) to an individual who qualified by examination (R.C. 4740.01(A)), who then assigns it to a contracting company. Other states' reciprocity forms pair this license with their master HVAC or mechanical contractor licenses, so it is treated here as the master level. A new applicant must be 18, a citizen or legal alien, have five years as a tradesperson in the trade immediately before applying (or be an Ohio registered engineer with three years of construction business experience), pass BCI and FBI background checks, pass both sections of the PSI-administered examination (trade and Business & Law), carry $500,000 of contractor liability insurance in one company name, and pay a $25 application fee and $25 license fee per trade; licenses expire annually and renew with 8 hours of continuing education (24 for three-year renewals). OCILB's published reciprocity list covers HVAC licenses from Alabama, Kentucky, Louisiana, Mississippi, South Carolina, Tennessee and West Virginia (refrigeration from Alabama, Kentucky, Louisiana, Mississippi and Tennessee), with the Ohio Business and Law exam still required for Louisiana, Mississippi, South Carolina and Tennessee licensees. Federal EPA Section 608 certification is required of anyone handling refrigerants but is not part of the OCILB application.

Mississippi does not issue a personal master HVAC license. The state-level HVAC credential is the Mississippi State Board of Contractors (MSBOC) contractor license: commercial 'Heat, Ventilation, A/C - HVAC' under the Mechanical classification (required on commercial jobs over $50,000; application and renewal $400, $300,000/$600,000 liability insurance, CPA-reviewed financial statement) or Residential HVAC (required for residential work over $10,000 in remodeling or $50,000 new construction; application $50, renewal $100). The license is issued to the business through a Certificate of Responsibility with a named qualifying party who passes the open-book PSI HVAC (or Residential HVAC) trade exam and the mandatory Mississippi Law and Business Management exam, so a master HVAC mechanic who only wants to work for an employer has nothing to transfer to at the state level; the personal master credential exists only in cities such as Southaven (Master Mechanical, $100, which itself requires an active MSBOC license, a $10,000 bond and liability insurance) and Gulfport (Mechanical/HVAC contractor license issued to the qualifying party, $100). MSBOC waives its HVAC trade exam, for $50 per exam, for qualifying parties who have held a license for at least one year with the Alabama Board of Heating, Air Conditioning and Refrigeration Contractors, the Alabama General Contractors Board, the Louisiana State Licensing Board for Contractors, the Ohio Construction Industry Licensing Board (HVAC or Refrigeration), the South Carolina Residential Builders Commission (Residential HVAC) or the Tennessee Board for Licensing Contractors, provided the license was obtained by that board's exam and there has been no disciplinary action in the period stated in each agreement; the Business and Law exam is never waived. EPA Section 608 certification is a separate federal requirement.
