Learning a trade requires hard work and determination. You can’t rush the process, but the time you put into learning how to be an HVACR technician or contractor can lead to a career that is long-lasting, lucrative, and fulfilling. There are 425,200 heating, air conditioning, and refrigeration mechanics and installers nationwide, according to the U.S. Bureau of Labor Statistics, and New Hampshire employs 2,120 of them.
Employment is projected to grow 8% from 2024 to 2034 throughout the country, adding more than 40,000 of these skilled workers to the ranks. In New Hampshire, that growth rate is expected to be at 7%, according to CareerOneStop, the U.S. Department of Labor’s job search website.

Contractors struggle to find skilled tradesmen like plumbers, electricians, and HVACR or mechanical professionals, while the demand for them continues to grow. According to the Associated General Contractors of America, construction industry employment in New Hampshire in July 2025 totaled 32,200, a decrease of 100 (-0.3%) from July 2024 and an increase of 3,500 (12%) from February 2020. If you get the training you need, you should have a variety of jobs to choose from when you’re ready.
A large part of what HVAC contractors and technicians do is replace and repair existing systems. As more emphasis is placed on energy efficiency and reducing pollution, systems need to be retrofitted, upgraded, or replaced entirely to comply with these new standards. Licensing requirements for HVAC contractors vary from state to state and, in some cases, from locality to locality. New Hampshire licensure has statewide requirements for gas fitters and mechanical business entities.
Licensing Requirements for HVAC Contractors in New Hampshire
Is a license required to work as an HVAC/mechanical technician in New Hampshire? Yes, if you work as a fuel gas fitter or own a mechanical business. The state of New Hampshire requires fuel gas fitter trainees, installers, and service technicians to obtain a state license. Mechanical businesses providing gas, plumbing, domestic appliance, or hearth services also must obtain a state license. The state does not issue licenses for HVAC workers if they do not work as a gas fitter.
The Board of Mechanical Safety and Licensing, within the New Hampshire Office of Professional Licensure and Certification (PLC), licenses fuel gas fitters and mechanical businesses. It provides a voluntary certification for oil heating technicians. The board also licenses trainee, journeyman, and master plumbers.
In addition, HVAC contractors must follow local licensing requirements, although in New Hampshire, they are minimal. For instance, the cities of Manchester and Nashua do not issue HVAC contractor licenses and only require contractors to follow the permitting process for projects within the city.
Types of HVAC Licenses in New Hampshire
What are the types of HVAC/mechanical licenses in New Hampshire? There are six types of HVAC-related licenses in the state.
Fuel Gas Fitting Trainee License — A fuel gas trainee is a person who is in the process of meeting the licensing requirements and works under the direct supervision of a licensed fuel gas fitter in the repair or installation of inside and outside piping from a gas meter or first-stage regulator. Work also includes the repair or installation of residential and nonresidential fuel gas appliances and equipment, which includes heating equipment systems, hot water heating systems, domestic appliances, or hearth equipment systems using liquefied propane gas or natural gas.

What Is the Mean Wage for an HVAC Technician in New Hampshire?
The annual mean wage for HVAC mechanics and installers in New Hampshire is $66,520, according to the U.S. Bureau of Labor Statistics. However, that salary can increase as you acquire more experience. An HVAC technician salary database, shared with ServiceTitan by Payscale.com, projects the median HVAC technician salary will increase nationally in 2025 by 3.44% for entry-level workers, 3.46% for intermediate level, 3.62% for senior level HVAC professionals, and 3.53% for supervisors. In New Hampshire, those salary projections are:
Entry (<2 years): $55,000
Intermediate (2-4 years): $66,800
Senior (4-7 years): $78,500
Supervisor (>7 years): $92,300
The meaning of a “mean” and “median salary” can be confusing. Here is the difference:
Mean tells you the mathematical average.
Median salary tells you the point at which 50% of workers make less and 50% make more, and is usually a better indicator of what most people actually earn.
Salaries can vary widely depending on the city where you work and other factors like education, certifications, additional skills, and the number of years you have spent in your profession. If you choose to start an HVAC business, this blog can give you an idea of what you can expect to make and what factors will influence that number.

Does My New Hampshire HVAC License Work in Any Other State?
No. New Hampshire does not have a state level HVAC license, so it does not have reciprocity agreements with other states.
What Are the Reciprocity Requirements for an HVAC License in New Hampshire?
Under New Hampshire HB 594 of 2023, out-of-state licensed professionals may obtain a New Hampshire license if they obtained their current license in a qualifying jurisdiction, which means the jurisdiction has similar licensing requirements to New Hampshire. There are currently no qualifying jurisdictions for gas fitters.
HVAC Specific Requirements: EPA Certification
Throughout the country, including in New Hampshire, federal-level EPA regulations under Section 608 of the Clean Air Act require that technicians who maintain, service, repair, or dispose of equipment that could release refrigerants into the atmosphere must be certified. EPA Section 608 HVAC Certification is required for any professional who conducts refrigerant line-pressure tests or handles or adds refrigerant to existing air conditioning systems.
Most training programs can direct you to how and where to get that certification, or your employer will require you to get it before handling refrigerant. You can also go to EPA.gov and key in 608 Certification in the search bar to find out which institutions in your state offer certification programs. All apprenticeships will include this preparation and testing.
Take Certification Exam: You must acquire your EPA Certification from an approved organization. A list of these organizations can be found on the EPA’s website. There are four types of EPA Certifications for Refrigerants. They allow for different levels of certification for different scopes of work.
Type I – For servicing small appliances containing five pounds of refrigerant or less.
Type II – For servicing high-pressure units that contain five pounds or more of refrigerant (including most small commercial and residential systems).
Type III – For servicing or disposing of low-pressure appliances.
Universal – For servicing all systems and appliances covered under Types I, II, and III. Generally, this is more useful than targeting any one specific certification.
Core Exam
For all certifications, you must pass the “Core Section” of the EPA certification exam. It covers the following topics:
Ozone depletion
Clean Air Act and the Montreal Protocol
Section 608 regulations
Substitute refrigerants and oils
Refrigeration
The Three R’s (Recover, Recycle, Reclaim)
Recovery techniques
Dehydration evacuation
Safety
Shipping
National HVAC Certifications
Other certifications can help you demonstrate your proficiency to potential employers and clients. North American Technical Excellence (NATE) certification, ASHRAE (American Society of Heating, Refrigeration and Air-Conditioning Engineers) certification, and other professional certifications are not required but add to your marketability as a service provider and therefore increase your opportunity to make more money.
