Connect With HVAC Schools

With the cold winters of the Granite State comes a thriving demand for workers in heating, ventilation, air conditioning, and refrigeration (HVAC-R). According to the New Hampshire Board of Safety, boilers and water heaters have a relief valve, which requires annual testing and needs to be replaced every five years. To meet this requirement and other HVAC needs, the Plumbers, Fuel Gas Fitters and HVAC Association of New Hampshire support these skilled professionals in their line of work, offering legal advocacy pertinent to issues in the industry and other resources.

So what can an aspiring HVAC mechanic or installer expect to do in New Hampshire (NH)? These workers must understand the basic heating & refrigeration cycles; calculate heat loads & losses; install, troubleshoot, or repair HVAC systems & components (e.g., metering devices, ductless splits, motors, humidifiers, temperature controls, electrical wiring, economizers, pumps, valves, fans); interpret mechanical drawings & blueprints; solder & braze parts; maintain detailed client service records; keep up-to-date on latest advances in the industry; and give customers recommendations on how to improve the efficiency of systems.

Additionally, some of these workers choose to pursue voluntary credentialing through the NH Department of Safety, and others may achieve national certification through entities such as HVAC Excellence or North American Technician Excellence (NATE), both discussed below in the licensure section of this page.

Some HVAC workers choose to specialize in a type of equipment or method, while others have more broad-based skill sets. Regardless of the specialty, contracting company, or equipment focus, all people nationwide who handle refrigerants must get the EPA Section 608 certification, also discussed below in the credentialing section.

Occupational Demand for HVAC Workers in New Hampshire

As mentioned above, the future looks bright for HVAC professionals in the US. By illustration, the Bureau of Labor Statistics (BLS 2021) predicted a 5 percent explosion in HVAC job openings between 2020 and 2030, which is slightly slower than the average for all occupations (8 percent). With the expected addition of 19,000 fresh openings in this industry around the country—some of them in NH and surrounding states of the northeast—the employment climate looks promising for the coming decade.

That said, the demand for HVAC technicians in NH is also growing at a slightly faster rate than at the national level. Projections Central predicts a 6.8 percent statewide increase in employment opportunities by the end of 2028.

Varied forces are contributing to the booming HVAC industry. First, these systems typically need to be replaced every 10 to 15 years, producing a relatively steady stream of work for the professionals that know how to do this. Second, regular service contracts and manufacturer recommendations for maintenance lend themselves to a thriving employment landscape for HVAC workers. Lastly, NH has very cold winters and as a result, there is typically a seasonal boom during those months in the installation and repair of equipment.

While some HVAC professionals work normal business hours, others will be called upon to work weekends, holidays, or evenings, especially during the busy winter season in NH. It’s important to note that people in this industry suffer a higher-than-average rate of injury compared to other American occupations. This is due to the type of equipment used and the physical nature of the job, demanding the lifting of heavy loads, dealing with sensitive chemicals such as refrigerants, and reconfiguring electrical wiring.

These activities put workers at a higher risk for muscle strains and tears, as well as burns, electrical shock, and lesions. While these threats loom, they can generally be kept to a minimum with adequate training and the donning of proper safety equipment.

As further proof of the growing market for HVAC workers in NH, an analysis of common job post websites yielded some promising results. For example, Indeed (October 2021) had 122 relevant job openings in HVAC at places such as Phillips Exeter Academy, AGS Services, Bosch Group, and Aucella. Monster (September 2021) boasted additional openings with employers including EMCOR Group, Honeywell, and Brighton Installation. In sum, there’s ample evidence that opportunities in this field are on the rise in New Hampshire.

New Hampshire (NH) HVAC Tech & Installer Salaries

Not only is there a booming market for HVAC services in New Hampshire and across the country, but it is also one of the highest paying fields for people with one to two years of postsecondary training. The Bureau of Labor Statistics (BLS May 2020) reported that the 344,020 HVAC mechanics and installers around the country had an annual average salary(Annual mean wage) of $53,410, only slightly lower than the average salary for all occupations (including people with bachelor’s degrees and beyond) at $56,310 (BLS May 2020).

Following are the more detailed salary percentiles for HVAC professionals nationwide as compared to New Hampshire (BLS May 2020):

United States New Hampshire
Number of HVAC professionals employed 344,020 2,100
Annual mean wage $53,410 $56,660
10th percentile $31,910 $36,770
25th percentile $39,320 $44,850
50th percentile (median) $50,590 $56,260
75th percentile $64,350 $66,190
90th percentile $80,820 $79,480


The national figures were slightly different according to another source of data, PayScale (October 2021), which relies on self-reported salaries. Among the HVAC workers reporting their annual salaries, Payscale found these percentiles:

  • 10th percentile: $32,000
  • 50th percentile (median): $49,655
  • 90th percentile: $78,000

As noted above, the average salary for HVAC workers in New Hampshire is slightly higher than that of the rest of the nation. As with any salary projections, taking into account the cost of living is also important. As such, the Missouri Economic Research and Information Center (MERIC 2021) found that NH was ranked 37th in affordability, making it more expensive than the majority of states. For HVAC technicians this means relatively high salaries may still not go as far as lower salaries in other states, so that is something to keep in mind.

The BLS designated seven regions within New Hampshire for which employment data is available. The 170 HVAC workers in the Dover-Durham, NH-ME area earned the highest average salary (annual mean wage) in the state, with a reported average of $61,780 per year.
