New York to Ohio: master HVAC technician license reciprocity

No credit· Start overVerified September 15, 2026· 9 sources

New York does not issue a statewide master HVAC technician license, so there is nothing to transfer. Here is Ohio's standard path for out-of-state applicants.

Your origin state does not issue a statewide license at this level, so there is no license to transfer. The destination's standard out-of-state path is shown; expect to meet it in full.

Reference only, not legal advice. Rules change; confirm with the licensing board before you apply. Full disclaimer.

Out-of-state HVAC or mechanical contractor licensee without a reciprocity agreement (examination route)

Your out-of-state credentials give no advantage. You meet the destination's requirements from scratch.

An HVAC, mechanical or refrigeration contractor licensed in a state without an OCILB reciprocity agreement must take the Ohio examination. R.C. 4740.06(C) and OCILB's Licensed Out-of-State Contractor Application let the out-of-state license stand in for the usual five years of Ohio tax and permit documentation: the applicant instead shows the license has been active for at least five years (letter of good standing), at least five building authorizations issued under it, one tax return reflecting income under the license (plus a W-2 if not the owner), and that their employer is registered in Ohio as a foreign corporation or LLC with a designated agent. After board approval (valid one year) the applicant completes BCI and FBI background checks, then passes both sections of the PSI exam (HVAC or Refrigeration trade section and Business & Law). The license is issued on submission of the results, a $25 fee and a $500,000 certificate of liability insurance, and must be assigned to a contracting company; HVAC and Refrigeration are separate licenses with separate applications and fees. OCILB describes no case-by-case endorsement that waives the exam outside a written reciprocity agreement. EPA Section 608 certification is a federal prerequisite for refrigerant work and is not verified by OCILB.

The PSI examination fee is published only in the PSI Candidate Information Bulletin sent to approved candidates and was not confirmed from an official page. R.C. 4740.06(F) requires the board to authorize the license within 90 days of the application when the applicant qualifies and passes the exam.

How Ohio licenses master HVAC technicians

Ohio master HVAC technician · “HVAC Contractor / Refrigeration Contractor (OCILB state license)”

Statewide license

Verified September 15, 2026· 6 sources

Issued by Ohio Construction Industry Licensing Board (OCILB), Ohio Department of Commerce

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.

Why New York has nothing to transfer

New York master HVAC technician

Licensed by cities and counties

Verified September 15, 2026· 22 sources

New York issues no statewide master HVAC, mechanical or HVAC contractor license; the Department of State licenses none of the construction trades, so the master-level credential exists only where a city or county has created one, and most have not. The only examined, person-holdable HVAC license in the state is Buffalo's Heating Contractor license from the Board of Heating Examiners (age 21, two years of heating installation experience, a quarterly written exam, a $10,000 bond, $1,000,000 liability insurance, $50 exam fee and $500 a year), which covers heating and process systems but not air-conditioning-only work. New York City has no HVAC or mechanical contractor license at all (the DOB licenses oil burner installers and the FDNY certifies refrigerating system operating engineers, but installation and service of HVAC systems needs no license), and the suburban counties regulate the trade through home improvement contractor licensing of the business: Westchester has required 'all HVAC professionals' to hold its home improvement license since July 1, 2025 ($750 application, no exam), Nassau's home improvement license ($650 for two years plus $50, five years of experience, no exam) covers central heating and air-conditioning work, and Suffolk's ($200 application and $200 a year, $500,000 insurance, no exam) covers HVAC ductwork. An out-of-state master HVAC license has no state-level recognition and none of these jurisdictions publishes reciprocity for it; a contractor from another state obtains the local business license (or, in Buffalo, sits the heating contractor exam) in each jurisdiction where they will work.

How local licensing works in New York

How local licensing works. With no state HVAC board, each jurisdiction that regulates the trade does so under its own code, usually as a business license with insurance and experience requirements rather than a trade exam. Buffalo is the exception with an examined heating contractor license.

New York City. The Department of Buildings issues no HVAC, mechanical or refrigeration contractor license; mechanical work is done under permits without a trade license, and the general contractor registration ($300 for three years) applies only to builders of one- to three-family homes. Oil-fired equipment must be installed by a DOB-licensed Oil Burner Equipment Installer (Class A or B; written exam $585, practical exam $530, $100 license for three years), and any refrigerating system that needs an FDNY permit must be supervised by a holder of the FDNY Q-01 Refrigerating System Operating Engineer Certificate of Qualification (EPA Universal certification, a 200-hour course or one year of qualifying experience or a boiler engineer, marine engineer or PE license; $60 plus $225 exam fees; three-year renewal $15). Neither recognizes out-of-state HVAC licenses.

Buffalo. City Code Chapter 238 makes it unlawful for any person to install, erect, alter, repair, service, reset or replace any heating or process system without a license from the Board of Heating Examiners; the separate City contractor license 'does not allow for plumbing, heating, cooling or electrical work'. Applicants must be at least 21 and have two years of practical experience installing heating equipment, a recognized school course plus one year, or be a graduate engineer; they submit photo ID, employer letters and a list of twenty completed installations to the Office of Fuel Devices, and if approved sit the Heating Contractor's Examination (offered roughly every three months, covering local ordinances and ASHRAE material). Classes: I (oil, gas or solid fuel), II (gas or solid fuel), III (wood-burning fireplaces and stoves). Fees: $50 non-refundable testing fee, $500 license, $500 annual renewal; a $10,000 bond to the City and certificates of $1,000,000 general liability and workers' compensation insurance are required. The license may be held by an individual, partnership or corporation. No reciprocity provision.

Rochester. Licenses stationary engineers and refrigeration operators (plant operation), electricians and plumbers; no HVAC contractor license.

Westchester County. The June 2025 amendment to the Consumer Protection Code requires 'all HVAC professionals' to be licensed through the Department of Consumer Protection as of July 1, 2025; the vehicle is the county Home Improvement Contractor license ($750 application fee effective January 1, 2026, $100 optional expedite, roughly 60 business days of document verification and background investigation, no exam). The county's examined trade licenses cover only plumbers and electricians.

Nassau County. Contractors installing or replacing 'central heating or air conditioning systems' in residential property need the county Home Improvement license: five years of recent verifiable experience, an establishment in New York State, liability, property damage and workers' compensation insurance, $650 for a two-year license plus a one-time $50 restitution fund contribution, $110 late renewal fee; no exam.

Suffolk County. Home improvement contracting expressly includes 'ductwork for heating, ventilation and air-conditioning systems'; the county Home Improvement license requires public liability and property damage insurance of at least $500,000 per occurrence and workers' compensation, a $200 application fee and $200 annual license fee ($50 temporary 90-day license); employees of licensed contractors are exempt; no exam.

Out-of-state holders. No New York jurisdiction publishes a reciprocity or endorsement path for out-of-state HVAC contractor or master licenses. Buffalo requires its own exam; the counties require their own business license regardless of any license held elsewhere; New York City requires no HVAC license at all.
