HVAC Schools in California: The Ultimate Guide

Accredited California HVAC Training Programs

According to the U.S. Bureau of Labor Statistics (BLS), “Because HVACR systems have become increasingly complex, employers generally prefer applicants with post-secondary education or those who have completed an apprenticeship.” Also, some craft workers enter apprenticeship programs after working as a helper. The Home Builders Institute offers a pre-apprenticeship certificate training (PACT) program for eight construction trades, including HVAC.

Formal education is not required by law in California for entry-level HVAC workers, but it can help you land that first job in the field. College education in a related field can also count for part of the experience requirement for licensing. In general, there’s a direct correlation between a degree and higher long-term earnings, so it could pay off in the long run. 

California has a few programs accredited by either of the two main organizations that approve HVAC programs and schools nationwide: HVAC Excellence and the Partnership for Air-Conditioning, Heating, Refrigeration Accreditation (PAHRA). These organizations evaluate the programs based on the facilities, the faculty, and whether the curriculum meets or exceeds industry standards.

HVAC Excellence has accredited four programs in California, and PAHRA has accredited one of those programs as well.

HVAC Excellence Accredited Programs

• Brownson Technical School

• Cypress College

• Mount San Antonio Community College

• North American Training Center

PAHRA Accredited Programs

• Mount San Antonio Community College

The National Center for Construction Education & Research (NCCER) has also approved several HVAC programs in California. NCCER lists the following programs on their website as accredited schools:

• Barstow Community College

• Cerritos College

• College of the Sequoias – Tulare College Center

• Imperial Valley College

• Kern Community College District, Workplace Learning 

HVACR Degrees & Certificates

As you weigh the benefit of getting some formal training at a technical or community college, you may want to speak with people in the field in your state. The licensing requirements vary from state to state, and some require a minimum amount of education. Other states, like California, don’t have educational requirements to become licensed. If the return on investment is not there in your state, it may make more sense to simply get an entry-level position and get on-the-job training. 

Regardless of the educational requirements by state, anyone who maintains, services, repairs, or disposes of equipment that could release refrigerants into the atmosphere needs Environmental Protection Agency (EPA) certification. More on that later.

In terms of college education for HVACR techs, typically there is a range of degree and certificate programs. The time it takes to complete them and the cost of each are the most significant differences. The most common HVAC programs are:

• Certificate Program – three to six months

• Diploma Program – one year

• Associates Degree – two years

• Bachelor’s Degree – four years

Obviously, the longer the program, the more it costs. Most HVAC professionals have some post-secondary training because the cooling and heating systems used to regulate our homes and businesses are becoming increasingly complex and technical. However, very few HVACR professionals choose to get a four-year bachelor’s degree unless they’re seeking an engineering degree to design and develop those complex systems.  If this is a path that interests you, you may want to explore the Mechanical Engineering Bachelor of Science degree at one of the four-year universities in California like:

• California State Polytechnic University – Pomona

• California State Polytechnic University – San Luis Obispo

• California State University – Long Beach

• San Jose State University

• Santa Clara University

• Stanford University

• University of California-Berkeley

• University of California-Davis

• University of California-Irvine

• University of California-Santa Barbara

• University of California-Los Angeles

• University of California-San Diego

• University of Southern California

As stated earlier, in many cases but not always, formal education pays off in the form of higher wages. 

Typical Courses in Technical College Programs

HVAC programs at technical colleges or trade schools are all intended to prepare students for careers in the refrigeration, air conditioning and heating industries. All combine theory and hands-on training needed to do the job. Most encourage students to work in their field of interest while attending school if pursuing a longer degree, and many are designed with that in mind. One-semester programs typically prepare students to find entry-level work upon completion. 

For the certificate programs, the coursework is specialized. Broader programs of study for lengthier diploma programs would incorporate classes on blueprint reading, gas heat, heat pumps and related systems, refrigeration fundamentals, principles and practices and system components. Air Conditioning certificates or diploma programs would also include classes on air conditioning systems application and installation and troubleshooting air conditioning systems.

Students pursuing an associate’s degree in Applied Science will need to fulfill general education coursework in addition to the specialized HVACR classes to meet the more rigorous requirements for that associate degree.

School Selection Criteria

There are a lot of things to consider when picking the right school and program.

Cost

Cost is, of course, at the top of the list. According to Community College Review, tuition at California community colleges on average is $1,997 per year for in-state students and $7,123 for out-of-state students. Some programs listed here can be upward of $15,000 just for tuition and $20,000 to $30,000 for off-campus living costs. There will be some variations in fees at each school, though, so be sure to review all of the costs involved. 

There are also always costs for books and tools, but those tools are yours to keep as you enter your chosen occupational field. All students who are interested in receiving federal (Pell Grant) and any state grants apply by completing the Free Application for Federal Student Aid (FAFSA) form online.

At least one college in California has a free training program designed to give students the basic knowledge they need to get started as an entry-level HVAC technician. Barstow Community College offers a nine-week tuition-free workforce development program to get participants work-ready quickly.

Program Length

As noted above, you can choose from a specialized certificate or a broader diploma or associate’s degree. The certificates can require as few as 12 to 16 credit hours (called units in California) and take one semester to complete. Others may consist of as many as 45 credits and take three semesters but can be done within a year if students continue through the summer sessions. Associate’s degree programs typically take two years.

Benefits

There are many benefits to getting formal education if you want to join the HVACR profession. Although California does not require formal education to get started in the field, many employers will choose an applicant with a certificate or degree over one without credentials. Having some basic knowledge helps you to hit the ground running and secure your place in a shop full of professionals. Technical training is also usually rewarded with higher starting pay and lifelong earnings.

Online vs in-person

You may choose to get HVAC training through an online certificate program. Only you know if this type of independent curriculum will work for you. Both Penn Foster and Ashworth College offer online HVAC classes. Brownson Technical School also offers an HVAC/R blended online 40-week program.

Online programs are ideal for people looking for entry-level HVAC jobs or for entry-level workers who are looking to increase their salary. HVACClasses.org gives a detailed description of some of the top online programs nationwide. If you know your learning style relies on personal instruction, more traditional in-person classes are accessible throughout the state.

Level of difficulty

HVACR programs are designed to prepare graduates for entry-level positions in the HVAC industry in commercial, industrial, or residential sectors. Curriculum includes an understanding of mathematics and physics. 

HVAC technicians have to learn to do a lot of different things to be successful, including how to follow blueprints or other design specifications to install or repair HVAC systems, connect systems to fuel and water supply lines and air ducts, install electrical wiring and controls, proper techniques of refrigerant recovery, reclaiming and recycling, run diagnostics, and so much more. 

The BLS describes the many duties of a HVAC mechanics and installers this way: Install, clean, and maintain HVACR systems; Install electrical components and wiring; Inspect and test HVACR systems and components; Discuss system malfunctions with customers; Repair or replace worn or defective parts; Recommend maintenance to improve system performance; Keep records of work performed. And, of course, especially in residential HVAC work, customer service is key.

School Comparison: At a Glance

Some of the accredited training schools listed above are part of the California Community College System. They offer financial aid in the form of grants and loans. The average community college acceptance rate in California is 83%. Let’s begin with the schools accredited by HVAC Excellence and PAHRA.

Brownson Technical School in Anaheim has three programs dedicated to HVACR, and tuition for each costs about $17,500. If you can’t commute and need housing, that will likely cost more than $25,000 more for the duration of the program.

Steps for Enrollment in California

Every college has its own way of doing things, but in general the process begins with visiting the school’s website and applying for admission online. Some require that you pay an application fee and provide several documents. In general, the application process has the following steps:

1. Complete your application.

2. Pay the application fee (if applicable).

3. Provide proof of residency to qualify for in-state tuition.

4. Have sealed official high school transcript or GED scores sent.

5. Submit placement test scores.

6. If applicable, apply for on-campus housing.

If you choose to start with an apprenticeship, you will want to contact the Local Union or non-union trade organization chapter closest to you. Each organization has a slightly different application process, but the application requirements in general are:

• Must be at least 18 years of age.

• Must be a high school graduate, senior scheduled to graduate or have earned a GED certificate. Applicants will be required to provide a copy of their diploma or GED certificate, and an official transcript of their grades following submission of the application.

• Must have a valid driver’s license.

• Have passed high school algebra or an equivalent post-high school algebra class with a “C” or better or pass an aptitude test.

• Pass a drug screen and criminal background checks.

HVAC Career Requirements in California

California does not have an educational requirement to legally perform entry-level HVACR work in the state but does require years of experience. Entry-level professionals just need to meet employer expectations to get started working for a licensed contractor. The California Contractors State License Board issues HVAC contractor licenses. To be eligible applicants must provide documentation of four years of  journeyman-level experience. That experience can be entirely hands-on, or up to three years of it can be in an approved college or vocational training program. But at least one year must be in the field. Also, if you want to own your own HVAC business, you will want to get your license. For a detailed explanation of California’s HVACR licensing requirements and how to fulfill them, check out our essential guide to getting your California HVAC License. 

No matter what state you live in, there are Environmental Protection Agency requirements at the federal level for technicians who maintain, service, repair, or dispose of equipment that could release refrigerants into the atmosphere. According to EPA regulations under Section 608 of the Clean Air Act, this applies to any professional who conducts refrigerant line-pressure tests or handles or adds refrigerant to existing air conditioning systems. EPA certification is often part of HVAC degree programs. If you choose a shorter certificate program, you may need to get EPA certification on your own. Your employer should be able to guide you to resources, or you can find them in our California HVAC License guide.

Industry Apprenticeships 

Another way to get the training you need to become an HVAC mechanic or installer is through a formal apprenticeship. Most apprenticeships are three to five years long and require you to be at least 18 years old, have a high school diploma or a GED, and a valid driver’s license. 

The Plumbing Heating Cooling Contractors Association of California (PHCC) has three different apprenticeship programs — a Trainee Program offered to employers who perform residential and/or private commercial work, a State Approved Apprenticeship Program and a Federally Approved Apprenticeship Program that is registered with the U.S. Department of Labor (USDOL) meaning it must be at least four years long and include at least 144 classroom hours for each of those four years.

The Air Conditioning, Refrigeration and Mechanical Contractors Association of Southern California, Inc. (ARCA/MCA Southern California) has nine training centers across the state. Union HVAC apprenticeships are also offered in California through the United Association local union chapters — LU 460 Bakersfield, LU 114 Santa Barbara, LU 467 San Mateo, LU 62 Santa Cruz, LU 364 Colton, LU 342 Oakland, LU 246 Fresno, LU 250 Los Angeles, LU 159 Martinez, LU 228 Marysville, LU 442 Stockton, LU 582 Santa Ana, LU 398 Pomona, LU 447 Sacramento, LU 230 San Diego, LU 38 San Francisco, LU 393 San Jose, LU 403 San Luis Obispo, LU 343 Vallejo-Napa, and LU 484 Ventura.

They are five years long. Each year includes 1,700 to 2,000 hours of on-the-job training and a minimum of 246 hours of classroom courses, including basics such as mathematics, science, drafting, welding and other trade-related courses. Apprentices work for member contractors with an opportunity for increased wages each year until reaching journeyman status.

Some HVAC companies will hire applicants who have had no previous training and provide the training themselves — creating an in-house apprenticeship. A pretty typical model of that is pairing a new employee with an experienced technician for the hands-on part of training and then requiring new hires to attend classes at night at a local community college or sometimes taught through the company itself. This typically includes getting EPA Certification and other HVAC certification such as North American Technical Excellence (NATE) certification as a way to demonstrate your proficiency. The state also has a website dedicated to registered apprenticeships for job seekers. 

Other School Options

We’ve highlighted accredited colleges with technician programs thus far and, although accreditation can give you confidence in your technical or community college, accredited programs are far from your only option in California. There are so many other programs throughout the state to choose from that may be more accessible to you based on where you live. Butte College, for instance, offers eight HVACR programs. There are just too many to list them all here, but in addition to all those already mentioned, each of the schools below has HVAC programs.
