Occupational Demand for HVAC Workers in Seattle, WA

The demand for HVAC technicians nationwide continues to grow. According to the BLS (2020), the number of openings for HVAC professionals is expected to swell 4 percent between 2019 and 2029, as fast as the average for all occupations during that time period.

It’s worth noting that Washington state is expected to have even more robust growth in industry. In fact, Projections Central (2020)—a data organization partnered with the US Department of Labor—reported that there would be a 15.5 percent increase in HVAC positions across Washington between 2018 and 2028. With the predicted addition of 1,280 fresh HVAC positions in WA and 42,800 openings nationwide, there is ample evidence that this is a promising profession in WA and across the country.

HVAC growth is fueled by several factors, including the economy. Every new office or residence requires climate control. Existing buildings need to have obsolete equipment replaced or retrofitted. The emphasis on energy conservation and pollution reduction means that systems have to be regularly serviced and maintained. HVAC professionals work indoors and outdoors, sometimes in adverse weather conditions. They may also have to work in cramped areas that force them into awkward positions. It’s worth noting that technicians may experience a higher rate of injury than workers in other trades. Injuries can include electrical shocks or muscle strains from moving heavy equipment.

The BLS (2020) reported that approximately 7 percent of HVAC/R technicians are self-employed. The remaining technicians are employed by contractors, schools, or retail and wholesale companies. Technicians usually work full time, although many put in overtime hours in evenings or on weekends during seasons of peak demand.

To best illustrate the thriving demand for HVAC workers in Seattle, turn to an online job site. For example, Indeed (2020) listed 147 local openings for HVAC/R technicians. These included listings from companies such as Innovative Refrigeration Systems, Day & Nite Plumbing & Heating, Bainbridge Heating and Air, and AAA Heating & Air Conditioning, among others. The Seattle-based listings on Monster (2020) found 550 jobs at companies like CyberCoders, Bassett Home Heating, EMCOR Group, and American Homes 4 Rent.

HVAC Worker Salary in Seattle, WA

HVAC mechanics and installers nationally received a median salary of $48,730 according to a May 2019 BLS report. Technicians in Seattle, WA received an annual median salary of $62,710. As with any salary projections, taking into account the cost of living is also important.

It’s worth noting that while HVAC workers in Washington had higher salaries than the national figures, the state also has a slightly higher cost of living, as well. To be sure, the Missouri Economic Research and Information Center (MERIC 2020) asserts that Washington is the fourteenth most expensive state in the country. That is certainly an important consideration.

The table below compares national, state, and regional salaries of HVAC professionals:

United States Washington Seattle, WA
Number of HVAC Professionals Employed 342,040 6,750 3,930
Average Mean Wage $51,420 $61,300 $67,750

  • 10th percentile: $31,000
  • 50th percentile (median): $47,775
  • 90th percentile: $75,000

Accredited HVAC Schools in Seattle, WA


Although inexperienced workers can obtain positions as trainees, there are significantly more opportunities for those who have completed an apprenticeship program. These offer the benefit of paying students as they learn. Apprenticeships typically include at least 2,000 hours of on-the-job training and 144 hours of classroom work annually. Apprentices are paid for the hours worked, and many programs do not charge tuition for the classroom work.

Apprentices must register with and be approved by the Washington State Apprenticeship and Training Council (WSATC). Any workers who are not registered apprentices are regarded as journey-level workers and must be paid the prevailing journey-level wage. Registered apprentices are paid prevailing wages for apprentices, which are based on the number of accumulated hours. After registration, apprentices can then enter the program of their choice.

The Washington State Department of Labor & Industries offers several programs statewide for HVAC/R applicants. These programs are designed to teach a particular skill, either through coursework or hands-on experience. The time to completion varies by program.

HVAC Certification & Licensing in Seattle, WA

Federal law requires all HVAC technicians who work with refrigerants to obtain the Environmental Protection Agency (EPA) Section 608 Certification. Certification requires passing an exam on the safe handling of refrigerants. Certifications are defined as follows:

  • Type I – technicians may work on small appliances
  • Type II – technicians may service high-pressure and very high-pressure appliances
  • Type III – technicians may service low-pressure appliances
  • Universal – technicians may service all types of equipment

Testing is provided by various industry organizations. The state of Washington does not require technicians to obtain an HVAC license. However, technicians are required to have a trainee or journey-level electrical license.

Additionally, the City of Seattle may require refrigeration and gas piping licenses, as well as an electrical license. Technicians start with a trainee license. Applicants are not required to have experience or coursework to receive the license. Trainees must renew their license every two years until they pass the tests to achieve journey-level electrical licenses. They are required to have 24 hours of continuing education a year.

The next step is to obtain an 06b electrical license, which is a restricted journeyman license. It requires 2,000 hours of supervised work with a certified electrician and passing a test. Licensees are then able to work without supervision on 240v 120a single-phase systems.

Technicians performing commercial work must obtain an 06a journey-level electrical license. These applicants must have 4,000 hours of documented work and pass a test. Once licensed, they are not restricted to systems on which they may work. Both licenses require specified continuing education hours of coursework and renewal.

Seattle also has three levels of refrigeration licensing:

  • Journey refrigeration mechanic – technicians are allowed to install, repair, or alter refrigeration or air conditioner equipment
  • Refrigeration operating engineer – technicians are limited to working on systems in specific buildings that are owned or operated by their employer
  • Refrigeration and air conditioning contractor’s license – contractors may install, repair, or alter refrigeration or air conditioning equipment

Some Seattle HVAC technicians must also obtain gas piping licenses. All licenses require testing, fees, and must be renewed annually. Technicians may obtain additional training and certifications from industry organizations. These include, but aren’t limited to:

  • Refrigeration Service Engineers Society (RSES) – courses are taught by certified instructors and are available online; technicians can study basic and advanced HVAC and HVAC/R principles
  • North American Technician Excellence (NATE) – training and certification in HVAC and HVAC/R knowledge areas
  • HVAC Excellence – dedicated to improving HVAC technician competence through training and certification

Requirements and fees for the various certifications vary. To learn in-depth about national certifications, please visit the main HVAC credentialing page.
