Working as an HVAC technician in Massachusetts can be a rewarding career with the possibility of great longevity. Frigid winters and humid summers mean that both residential and commercial buildings have an ongoing need for climate control that works. HVAC technicians in the Bay State are currently in demand, with huge growth expected in specialty trade sectors as well as hospitals and educational settings.

According to the Bureau of Labor Statistics (BLS May 2022), 6,400 Massachusetts HVAC technicians were employed as HVAC installers, mechanical, and maintenance workers. In general, these workers use their skills for installing, maintaining, and repairing systems and equipment that control temperature and air quality.

One job may require putting piping and wiring for an installation. The next might require testing circuitry and components. Technicians need to be familiar with how components such as belts, motors, filters, valves, and fans function as part of a complete system.

HVAC technicians in Massachusetts can find professional support from trade organizations and unions like the UA Local 537. Local to Boston, this pipefitter’s union offers professional networking, training (including apprenticeships), and political advocacy.

It is also worth noting that the majority of work an HVAC technician does in Massachusetts does not require a specialized license; it is only working with industrial refrigeration units (over 10 tons in capacity) that requires licensing. A more flexible licensing system means that after completing training, new HVAC technicians in Massachusetts can start working and earning sooner.

Becoming an HVAC technician is an ideal career path for people who like to work with their hands, or those who are creative problem solvers, or those who want to have a great deal of autonomy in their work.

Occupational Demand for HVAC Technicians in Massachusetts

The demand for HVAC technicians nationwide continues to grow. According to the BLS (2023), the number of openings in this field is expected to grow 6 percent nationwide between 2022 and 2032—which is double the U.S. average across all occupations (3 percent). And Massachusetts is keeping pace with the national demand for technicians. In fact, Projections Central predicted a 18.5 percent statewide increase in HVAC jobs for the decade ending in 2030.

A few factors are contributing to the demand for HVAC technicians in the Codfish State (demand for refrigerated seafood storage is certainly one of them). Not only is there a continued demand for new commercial and residential HVAC systems as the construction of new structures grows, but climate-control systems generally must be replaced every 10 to 15 years.

Furthermore, the maintenance and repair of existing systems coupled with improving technologies for energy efficiency necessitate the availability of qualified HVAC technicians in Massachusetts and beyond.

It is important to note that there is a relatively high rate of injury for HVAC technicians and installers due to the physical nature of the occupation. Some common injuries include electrical shocks, muscular strains, tears, or burns. Technicians must ensure that they have the proper training and safety equipment and follow procedures to prevent these occurrences.

Finally, the BLS (2023) estimated that 8 percent of HVAC technicians nationwide were self-employed and can dictate their schedules. The majority (67 percent), however, work for manufacturing and contracting organizations. Some work typical business hours while others—especially in the busy winter and summer seasons—may have to work weekends, holidays, or evenings to serve client needs.

Since job boards can offer a peek into the real hiring needs in a region, it is illuminating to look at Indeed (Nov. 2023) for HVAC jobs in Massachusetts. One search found 808 HVAC jobs in the state, including listings from companies such as Rodenhiser Home Services Inc, Lavallee Systems, GEM Plumbing & Heating, and Greater Lowell Technical High School, among others. A similar search on Monster (Nov. 2023) found hundreds of jobs at companies like Multi-Flow Industries LLC, All Service Equipment Corp., Affinity construction, and Town Of Andover.

HVAC Technician Salaries in Massachusetts

According to the Bureau of Labor Statistics (May 2022), HVAC professionals earn relatively competitive salaries, particularly for positions that may require just two years of post-secondary training. BLS (May 2022) states, the median salary for HVAC workers nationwide was $57,460 per year, while the median salary for HVAC technicians in MA was even higher at $70,010 per year. In more detail, here were the salary percentiles of HVAC professionals across the US and in Massachusetts specifically:

United States Massachusetts
Number of HVAC professionals employed 374,770 6,400
Annual mean wage $57,460 $70,010
10th percentile $36,170 $45,760
25th percentile $44,100 $58,230
50th percentile (median) $51,390 $66,920
75th percentile $65,630 $76,930
90th percentile $94,340 $94,340


The national figures were slightly different according to another source of data, PayScale (Nov. 2023), which relies on self-reported salaries. Among the HVAC workers reporting their annual salaries, Payscale found these percentiles:

  • 10th percentile: $35,000
  • 50th percentile (median): $54,827
  • 90th percentile: $84,000

As noted above, the average salary for HVAC workers in Massachusetts is significantly 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 2023) found that MA was the second most expensive state, coming in behind only Hawaii. 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.

Accredited HVAC Training Programs in Massachusetts

Although approval from the state is the most important factor in choosing an HVAC school in MA, applicants may also want to consider programmatic accreditation. Two organizations in the US accredit HVAC programs: HVAC Excellence and the Partnership for Air-Conditioning, Heating, and Refrigeration Accreditation (PAHRA).

As of December 2021, there are no programs in Massachusetts that have earned accreditation from HVAC Excellence. Two programs in MA are accredited by PAHRA, but they are technical high school-level programs, which are outside of the scope of this page.

For more information on the programmatic accreditation process, interested technicians may visit the sites for either organization or the main HVAC programs page on this site.

Additionally, some schools undergo third-party institutional accreditation processes that are not specific to HVAC programs. For instance, the Accrediting Commission of Career Schools and Colleges (ACCSC) offers evaluation and accreditation to many continuing education and technical schools. ACCSC evaluates schools based on rates of student achievement, student graduation, and graduate employment. While this type of accreditation is not endorsed by the state of Massachusetts, it can be helpful when comparing HVAC schools in MA.
