HVAC Training Schools in California

Connect With HVAC Schools

With California (CA) under the constant threat of drought and record-breaking temperatures every summer, it is no surprise that the demand for qualified HVAC professionals in the Golden State has been on the rise.

Fortunately for workers in heating, ventilation, air conditioning, and refrigeration (i.e., HVAC-R or HVAC), there is a wealth of professional associations, trade groups, and other networking opportunities around the state. For instance, the Air Conditioning Trade Association (ACTA) based in Manteca, CA is a nonprofit group that organizes educational seminars, apprenticeships, and events to support HVAC workers.

Additionally, the California Plumbing-Heating-Cooling Contractors (PHCC) Association provides legal advocacy, widespread training events, conferences, and a federally registered apprenticeship program in its mission to remain “dedicated to the advancement and education of the plumbing and HVAC/R industry for the health, safety, and comfort of society and the protection of the environment.”

The vast array of professional groups and societies is only part of the good news. The Bureau of Labor Statistics (BLS May 2019) reports that as of early 2021, California boasts 29,650 HVAC mechanics and installers—the second-most among US states—and pays an average annual salary of $59,550—significantly higher than the national average in this occupation ($51,420).

HVAC workers in CA and beyond take on a variety of responsibilities such as installing, maintaining, and repairing HVAC systems and components; reading blueprints; ensuring compliance with local, state, and federal regulations; responding to customer service needs and educating clients on the proper use of HVAC equipment; documenting all activities in a logbook; testing parts for proper functioning and energy efficiency, and maintaining their state licensure through the CA Contractors State License Board. HVAC professionals may work across a range of systems, or they may specialize in a specific technique or technology (e.g., solar panels, commercial refrigeration, testing & balancing).

HVAC workers not only ensure that residential and commercial spaces are comfortable for people, but they also safeguard the transport of perishable foods and medicines, providing an invaluable service in California and across the country.

Occupational Demand for HVAC Technicians in California

As mentioned in the introduction, there is a strong demand for HVAC technicians, mechanics, and installers in California. The CA Employment Development Department (EDD) points out that as the state population continues to grow, so too does the construction of new residential, commercial, and industrial structures, which need temperature-control systems. The EDD also mentions that as HVAC technologies, components, and legislation continue to evolve and often increase in complexity, the demand for qualified HVAC professionals rises.

Further, HVAC systems not only require regular maintenance but also typically need to be replaced every 10 to 15 years, again requiring a trained professional for removal and replacement. HVAC technicians are expected to have an increasing role in installing and maintaining energy-efficient products as part of the emphasis on green technology.

Figures from the Bureau of Labor Statistics (BLS May 2019) support the EDD’s promising assessment. By illustration, the BLS predicts a 4 percent increase in openings for HVAC installers and mechanics nationwide between 2019 and 2029. This is as fast as the average growth projected for all occupations during that period (4 percent). With the addition of 15,100 opportunities for HVAC workers around the country, the career landscape in this field has a decent future.

According to the BLS (2019), nearly 7 percent of HVAC workers were self-employed in 2019, while 66 percent were in the plumbing, heating, and air conditioning contractors industry. While some HVAC techs in CA work normal business hours, others may be called upon to work evenings, weekends, or holidays, particularly in the busy winter and summer seasons.

As a further testament to the abundant opportunities in this field, Indeed (2021) posted recent job opportunities with CA-based employers such as Lennox International, Ralphs, Sunbelt Rentals, TechFlow, Sears Home Services, and Commercial Appliance Service LLC, to name a few. Monster (2021) had a whopping 3,724 jobs at organizations such as Blair Heating and Air, EMCOR Group, Apex Systems, Jobot, ABM Industries, and CyberCoders.

HVAC Technician Salaries in California

As mentioned in the introduction, not only do HVAC workers in California have a bright employment climate replete with job openings, but they also get paid more on average than HVAC professionals nationwide. As proof of point, the Bureau of Labor Statistics (May 2019) found that the 342,040 HVAC workers around the country had an average annual salary (annual mean wage) of $51,420. In California, the 29,650 workers enjoyed a mean annual salary of $59,550.

In granular terms, the BLS (May 2019) found the following national and state-based percentiles for HVAC technicians, mechanics, and installers:

United States California
Number of HVAC professionals employed 342,040 29,650
Average annual salary $51,420 $59,550
10th percentile $30,610 $33,580
25th percentile $37,660 $41,730
50th percentile (median) $48,730 $56,690
75th percentile $62,070 $71,710
90th percentile $77,920 $93,740

It is important to keep in mind that while the salaries for HVAC workers in CA are relatively generous, the cost of living in the Golden State is also higher than most US states. The Missouri Economic Research and Information Center (MERIC 2020) found that California was the third most expensive state, coming in behind only the District of Columbia and Hawaii.

HVAC Apprenticeships in California

There are various routes to becoming a qualified HVAC professional in California. In the past, pursuing an apprenticeship under the guidance of an experienced professional was common. Apprenticeship programs today typically last three to five years and involve at least 144 hours of formal instruction and 2,000 hours in the field.

For example, the Air Conditioning and Refrigeration Joint Journeymen and Apprentice Training Center based in Los Angeles is open to applicants with at least a high school diploma or GED and proof of having completed specific coursework (e.g., algebra, geometry) or passing a qualifying math exam.

Accredited HVAC Programs in California

These days, it is increasingly common for HVAC professionals in CA to enroll in a diploma, certificate, or degree program at an accredited school.

HVAC Licensing & Certification in California

There is one mandatory certification for all people nationwide who work with refrigerants: the EPA Section 608 certification. There are four subtypes of this credential: type 1 (small appliances), type 2 (high-pressure appliances), type 3 (low-pressure appliances), and type 4 (universal). Many vocational and trade schools in CA offer preparation for one of these exams as part of their curricula. For those that do not, the Environmental Protection Agency provides a list of Section 608 certification programs.

There is also a wide range of skills-specific certifications for HVAC professionals in CA offered through North American Technician Excellence (e.g., Industry Competency Exams or ICE); HVAC Excellence (e.g., Heating, Electrical, Air Conditioning Technology Plus); the Refrigerating Engineers and Technicians Association (e.g., entry-level Certified Assistant Refrigeration Operator); and others.

These credentials can demonstrate various competencies and enhance an HVAC technician’s employment prospects or salary. To discover the wide range of national certifications available, please check out the main HVAC certifications page.

Finally, state licensure is mandatory for HVAC workers in CA who provide services over $500. The main state credentialing agency is the CA Contractors State License Board. To become licensed as an HVAC professional, a person must meet the following requirements:
