The Evergreen State is not only replete with lush vegetation, but the relatively wet and cool climate also makes it a fertile employment landscape in the field of heating, ventilation, air conditioning, and refrigeration (HVAC-R or HVAC).

In addition to the bright career outlook, there is an array of professional associations and advocacy groups to support those in this line of work. The Plumbing, Heating, and Cooling Contractors of Washington State is a resource-rich agency that has a biannual magazine and is “dedicated to the promotion, advancement, education, and training of the industry for the protection of our environment and the health, safety, and comfort of society.”

So what do HVAC professionals in Washington (WA) do? According to the Bureau of Labor Statistics (BLS 2023), HVAC professionals take on responsibilities such as installing and troubleshooting HVAC systems and their components (e.g., heat pumps, boilers, furnaces, electric wiring, motors, pumps, ducts, hermetic compressors, burners, intake & exhaust fans, humidifiers, economizers); keeping detailed client records; calculating heat loads & losses; interpreting blueprints; making suggestions for improving energy efficiency; and maintaining all certifications and local licensure through the Washington State Department of Labor & Industries, an agency which offers state HVAC credentials as a subtype of electricians’ licenses.

It’s important to note that for all individuals who work with refrigerants (environmentally sensitive chemicals), there is one mandatory credential: the EPA Section 608 certification. A majority of HVAC technician training schools in Washington offer EPA 608 certification training as part of their programs.

Occupational Demand for HVAC Technicians in Washington

As mentioned above, the employment prospects for HVAC workers look very bright in Washington and throughout the country. The Bureau of Labor Statistics (BLS 2023) anticipated a 6 percent increase in HVAC job openings between 2022 to 2032 across the country, slightly faster than the average growth expected across all occupations during that period (3 percent).

These professionals are hired in a range of environments such as residences, commercial structures, schools, retail spaces, factories, and all buildings which seek climate control. As proof of point, popular job sites are bursting at the seams with openings in HVAC in WA.

Indeed (November 2023) lists more than 400 posts at places such as the University of Washington, BOEING, Seattle Public Schools, and Johnson Controls. Job site Monster (November 2023) details additional positions at Randstad, TemperaturePro Baton Rouge, and CoolSys Inc.

In addition to the wide array of environments in WA which employ HVAC workers, the maintenance of equipment and average lifespan of systems (which amounts to approximately ten years) also contributes to a steady stream of work in this area.

While the future looks bright in HVAC, it is crucial to point out that professionals in this line of work incur a higher-than-average rate of disease and injury compared to other occupations. The threat of muscle strains, chemical burns, skin irritation, and other ailments are relatively higher due to the physical nature of the work and the type of equipment used (e.g., refrigerants). That said, with the proper training and safety equipment, all of these problems can generally be kept to a minimum.

Washington State HVAC Technician Salary Data

Not only are the growth prospects for HVAC workers high nationwide and in WA, but among occupations with minimal postsecondary training, HVAC is one of the more lucrative lines of work.

According to the Bureau of Labor Statistics (BLS May 2022), there were 374,770 HVAC workers employed across the country with an annual average salary of $57,460; by comparison, there were 7,390 Washington HVAC professionals who enjoyed an annual average salary (annual mean wage) of $65,340, which is much higher than the national average.

Before digging into the detailed salary outlooks, it’s important to recognize that the cost of living in WA is relatively higher than the national average. The Missouri Economic Research and Information Center (MERIC 2023) reported that WA is the 7th most expensive state in the country, although it did boast relatively cheap utilities. Please keep this in mind while evaluating the wage prospects in this field.

The BLS (May 2022) found the following detailed wage percentiles among all HVAC technicians, mechanics, and installers around the country as compared to WA:

United States Washington
Number of HVAC professionals employed 374,770 7,390
Annual mean wage $57,460 $65,180
10th percentile $36,170 $44,030
25th percentile $44,100 $48,120
50th percentile (median) $51,390 $61,250
75th percentile $65,630 $76,690
90th percentile $82,630 $94,240

The national figures were slightly different according to another source of data, Payscale (November 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

The BLS designated 13 regions within Washington for which employment data is available. The 3,800 HVAC workers in the Seattle-Tacoma-Bellevue, WA Metropolitan Division earned the highest average salary in the state at $70,410.

HVAC Certification & Licensing in Washington State

As mentioned in the introduction, all HVAC professionals nationwide who work with refrigerants must have the EPA Section 608 certification. Four distinct types vary by category of equipment: type 1 (small appliance), type 2 (high-pressure appliances), type 3 (low-pressure appliances), and type 4 (universal). Please note that EPA 608 preparation is generally included as part of HVAC certificate and degree programs.

There are many other skill-based HVAC credentials available nationwide through groups such as North American Technician Excellence (e.g., industry competency exams or ICE), HVAC Excellence (e.g., HEAT Plus), and the Refrigerating Engineers and Technicians Association (e.g., certified assistant refrigeration operator).

To check out the gamut of HVAC credentials that confer proof of specific competencies, please visit the HVAC certifications page.

Finally, while the Washington State Department of Labor & Industries doesn’t have a specific division for HVAC licensure, it does offer licenses in this field through its electrician division. There are two types of specialty electrician licenses related to HVAC: HVAC/refrigeration system (6A) and HVAC/refrigeration – Restricted (6B). To qualify, candidates must have the following:

  • Completed application
  • Requisite experience (4,000 hours for 6A, 2,000 hours for 6B, or the equivalent) or education (48 classroom hours + experience for 6A, 24 classroom hours for 6B + experience)
  • Passing score on a comprehensive exam
  • Application fee

There are ways to secure these licenses if coming from a military background or from out-of-state as well. To renew, candidates must complete 24 hours of continuing education (CE) every three years. Please note that to garner the necessary hours to qualify for a specialty electrician license in HVAC, candidates must first become electrical trainees, another category of credentialing.

The Washington State Department of Labor & Industries also offers registration to contractor-level HVAC workers, both general and specialty. To qualify for a specialty contractor license in HVAC, applicants in WA must do the following:

  • Choose the business type (e.g., general partnership, sole proprietor, LLP, LLC, etc.)
  • Register with the WA Secretary of State
  • Complete a business license application & get an IRS employer identification number (if employing workers)
  • Get application notarized
  • Purchase bond & liability insurance ($6,000 for specialty contractor)
  • Show proof of general liability insurance
  • Pay registration fee

The contractor registrations are valid for two years. For all of the details, check out the WA Construction Laws & Rules.

Lastly, local laws and permitting may also apply to HVAC work. For example, the Seattle Department of Construction & Inspections issues several types of refrigeration licenses (e.g., journey refrigeration mechanic, refrigeration operating engineer, refrigeration contractor’s license, etc), which are all valid for one year. In sum, since municipal codes differ by region within WA, it is important to verify that one has all of the necessary local credentialing before completing HVAC work in the state.
