Unlike many states, a state-level license for general HVAC contracting or work solely related to cooling and ventilation was not identified in New Hampshire's published rules. However, if your work involves fuel gas appliances or piping, you will need a specific Fuel Gas Fitter license issued by the state's Office of Professional Licensure and Certification (OPLC) Board of Mechanical Safety. Understanding this critical distinction is the first step toward compliant operation in the Granite State.
Do You Need an HVAC License in New Hampshire? (The Key Distinction)
A state-level license for general HVAC contracting or work solely related to cooling and ventilation was not identified in the Board's rules. A state-issued Fuel Gas Fitter license is required for individuals who install, repair, or service fuel gas appliances and their associated piping systems.
This means if your work is limited to air conditioning, refrigeration, or ventilation systems that do not involve a fuel gas component, state-level mechanical licensing requirements were not identified in the reviewed rules. However, the moment your work involves gas-fired furnaces, boilers, water heaters, or other gas appliances, you must hold the appropriate license from the OPLC Board of Mechanical Safety.
What is the New Hampshire Fuel Gas Fitter License?
The New Hampshire Fuel Gas Fitter license is a state-mandated credential issued by the OPLC Board of Mechanical Safety that is required for installing, repairing, or servicing fuel gas appliances and piping systems. This license ensures that technicians working with potentially hazardous gas systems are qualified and knowledgeable about state codes and safety standards. Anyone whose work falls within this scope, from installing a new gas furnace to servicing a commercial gas boiler, must be properly licensed.
New Hampshire Fuel Gas Fitter License Tiers and Requirements
New Hampshire's Fuel Gas Fitter licenses are divided into specialty tiers, each with specific educational and experience requirements. The tier you pursue determines the scope of work you are legally authorized to perform.
The Fuel Gas Fitter tiers are distinct and define the types of work each is legally authorized to perform. Choose the tier that precisely matches your intended services to avoid scope-of-practice violations.
Piping Installer (Specialty License)
The Piping Installer license authorizes work on fuel gas piping systems.
- Experience Path:
- Minimum 48 hours of approved educational training.
- Minimum 1,000 working hours of on-the-job experience within a 60-consecutive-month period.
Installation Technician (LP or Natural Gas)
The Installation Technician license authorizes the installation of fuel gas appliances and associated systems.
- Experience Path:
- Minimum 72 hours of approved educational training.
- Minimum 2,000 hours of field experience under Saf-C 8000 (note the statutory 1,000-hour provision under RSA 153; this may be reduced if a formal educational program is completed).

For information on approved training and apprenticeship programs, consult the OPLC Board of Mechanical Safety.
Steps to Get a New Hampshire Fuel Gas Fitter License
Obtaining a Fuel Gas Fitter license in New Hampshire involves meeting specific experience requirements and submitting an application to the OPLC Board of Mechanical Safety.
- Meet Experience and Training Requirements. You must first complete and document the required on-the-job working hours and educational training hours for your desired license tier (Piping Installer, Installation Technician, or Service Technician).
- Complete the Application. Fill out the official application form provided by the OPLC Board of Mechanical Safety. Ensure all sections are completed accurately and include all required supporting documentation, such as proof of your experience and training.
- Pay Applicable Fees. Submit the required non-refundable license fee along with your completed application.
Is an Exam Required for a New Hampshire Fuel Gas Fitter License?
Yes. Under administrative rule Saf-C 8003.03, all new Fuel Gas Fitter applicants must successfully pass a written test with a score of at least 70%, covering the educational requirements (including NFPA 54, the National Fuel Gas Code) for the specialty license being sought. A state-level trade exam for general HVAC work was not identified in the reviewed rules of the Board of Mechanical Safety.
New Hampshire Fuel Gas Fitter License Fees and Costs
The initial Fuel Gas Fitter license in New Hampshire costs $190.00 for a two-year term, with specific fees for trainees and renewals.
- Initial Fuel Gas Fitter License: $190.00
- Fuel Gas Trainee Registration: $90.00

Insurance and Bonding Requirements for HVAC Contractors in New Hampshire
A statewide surety bond or general liability insurance requirement for individual Fuel Gas Fitter licensees was not identified in Saf-C 8000; however, state statute (RSA 153) requires business entities engaged in fuel gas fitting to provide proof of liability insurance prior to the issuance and renewal of a business entity license.
Renewing Your New Hampshire Fuel Gas Fitter License
New Hampshire Fuel Gas Fitter licenses are issued for two-year terms and require renewal with proof of continuing education.
- Renewal Cycle: Licenses must be renewed every two years.
- Continuing Education: To renew, you must complete 8 hours of board-approved technical instruction. At least 3 of these hours must be dedicated to the National Fuel Gas Code.
- Late Renewal: Failing to renew on time will result in penalties and a potential lapse in your license. If your license is expired for more than 12 months, you will face a significantly higher reinstatement fee.
Reciprocity and Endorsement for New Hampshire Fuel Gas Fitters
While RSA 153 authorizes the Board to enter into reciprocity agreements, active mutual-recognition or reciprocity agreements with other states were not identified in the reviewed rules. Out-of-state applicants should confirm any licensure-by-endorsement options or agreements directly with the OPLC Board of Mechanical Safety.
EPA Section 608 Certification for Refrigerant Handling (Federal Requirement)
The EPA Section 608 Technician Certification is a federal requirement for anyone who works with refrigerants, regardless of state-specific HVAC licensing. This certification is mandatory for HVAC professionals in New Hampshire who service, maintain, repair, or dispose of equipment that could release refrigerants into the atmosphere.
- Why It's Needed: This certification is mandated by the federal Clean Air Act to ensure the safe handling of substances that can harm the ozone layer and contribute to climate change.
- Types of Certifications:
- Type I: For small appliances (5 lbs. or less of refrigerant).
- Type II: For high-pressure appliances.
- Type III: For low-pressure appliances.
- Universal: For all types of appliances.
You must pass a federally-approved exam to obtain your EPA 608 certification.
