Trade Schools for HVAC

Virtually every building in the country has some type of heating, air conditioning, and refrigeration (HVAC-R) system hooked up to control the internal temperatures and air quality. Without these complex systems, our homes, offices, schools, stores, and other facilities would be either too hot or too cold, depending on the season. HVAC-R mechanics and installers (aka technicians) are specially trained to install, maintain, and repair these systems to ensure they work properly and without disruption. 

Because their skills are needed everywhere, HVAC-R technicians are always on the go, traveling to work sites where they may have to perform tasks outdoors or in tight spaces. Due to the various hazards associated with the job, such as risk of electrical shocks or pulled muscles from moving heavy equipment, HVAC-R techs must understand and follow many safety protocols to prevent mishaps. 

This knowledge and their necessary technical skills are taught in HVAC-R training programs at trade or vocational schools and community colleges. HVAC-R workers also learn through apprenticeships, or via a combination of both. 

What Is A Trade School for HVAC?

As explained by the Center for Employment Training, trade schools “focus on hands-on careers that require a base level certification or a specific number of on-the-job supervised hours to enter.” A job in HVAC falls under this category of “hands-on career” types.

HVAC trade school graduates can apply for apprenticeships, if they are 18, hold a high school diploma or GED, and, in some cases, have a valid driver’s license. They may also need to pass a drug screening to qualify. 

What to Expect at a Trade School for HVAC

Your HVAC trade school experience will be very practical. Trade schools are laser-focused on teaching the knowledge and technical skills necessary to get started in this dynamic field. They are a great way to establish a strong foundation prior to beginning an apprenticeship, which can take three to five years to complete. The more formal HVAC-R education a worker has under their belt, the shorter the apprenticeship should be. 

Length of HVAC Trade Schools

Trade schools for HVAC typically take between eight to twelve months to complete, with graduates earning a certificate. Short programs focus on preparing students to start in a particular area of HVAC, such as air conditioning. 

Longer programs are available for students who want to branch out beyond a single area of specialization. Students can also enroll in a two-year associate in HVAC-R, usually offered at community colleges or four-year schools. 

Types of Classes at HVAC Trade Schools

HVAC trade school classes are a mix of academic and hands-on learning. Ideally, students will already possess a basic understanding of general math, algebra, physics, and electronics. HVAC trade school websites will generally list their full curriculum along with an overview of the skills you’ll pick up, such as: 

  • How to read blueprints
  • How to set up residential and commercial HVAC-R equipment
  • How to perform routine maintenance, troubleshoot problems, and conduct repairs
  • How to braze and solder pipes and fittings, and
  • How to work safely with hazardous equipment

Section 608 Certification

Future HVAC-R workers who plan on servicing refrigerated equipment will likely need to study for Section 608 certification. This refers to the Clean Air Act of 1990’s Section 608 rule (or, more specifically, to 40 CFR Part 82, Subpart F), which requires that “technicians who maintain, service, repair, or dispose of equipment that could release refrigerants into the atmosphere must be certified.” The Environmental Protection Agency (EPA) oversees Section 608 certification, but trade schools can help prepare students for the exam. 

The EPA offers four basic certification types: 

  • Type I: for servicing small appliances 
  • Type II: for servicing high- or very high-pressure appliances
  • Type III: for servicing low-pressure appliances
  • Universal: for all types

Tuition rates for HVAC Trade School

HVAC trade school tuition rates vary but community colleges and vocational/trade schools tend to have much lower tuition and fees than four-year universities. 

  • Certificate programs may cost about $3,000 per year
  • Two-year associate’s degree could range from $3,000 up to $15,000 per year

Salary After Graduation from HVAC Trade Schools

HVAC-R technicians have a median annual wage of ~$49,000, per the Bureau of Labor Statistics. Top earners can make over $78,000 a year, while apprentices and entry-level workers may start at under $40,000, depending on worker qualifications, who the employer is, and which state they work in. Indeed, geographic location plays a big part in how much HVAC-R workers earn. Here are the top five locations with the highest annual mean wage:

  1. District of Columbia
  2. Alaska
  3. Hawaii
  4. New Jersey
  5. New York

Types of HVAC Classes or Topics

Common heating, air conditioning, and refrigeration classes offered via HVAC trade schools include: 

  • Airflow and indoor air quality
  • Basic electricity
  • Building codes
  • Heating fuels and heat pumps
  • HVAC-R theory
  • Installation and service
  • Mechanical drawings and diagrams
  • Piping
  • Principles of electric, gas, and oil heat
  • Refrigerant types
  • Safety practices
  • Soldering and brazing
  • Thermostats
  • Troubleshooting and problem solving
  • Venting and duct systems

Students can also take HVAC classes at certain community colleges, which may offer either a certificate or associate in HVAC technology. An associate degree will require general education classes in addition to the core HVAC subject matter and electives. As a result, an associate degree takes longer — usually about two years, if going full-time. 

As with any associate, programs require the completion of 60 semester units, and students must generally maintain a 2.0 GPA or higher to graduate. 

Of the total number of credits needed for a heating, air conditioning, and refrigeration associate degree, about one-third must be focused on the major, with related electives helping to round out the core requirements. Grades for core classes may need to be at least a C (or passing) or better to count for credit. 

While several aspects of HVAC-R are best learned in-person, many programs are nevertheless offered via a hybrid method (online and in-person), since apprentices will gain hands-on experience during their apprenticeship anyway. 

There are bachelor of science degree programs dedicated to heating, air conditioning, and refrigeration technology, but these are not aimed specifically at future HVAC-R technicians. Those finishing a four-year degree in HVAC-R technology may seek advanced career paths in sales engineering, design engineering, or project estimation and management. 

Most bachelor’s degree programs take four years if attending full-time, though some engineering programs can take an extra term or two. Part-time attendance can take up to twice as long, depending on course load. An HVAC trade school can lay a strong foundation for workers who want to start as technicians but later finish a bachelor’s to qualify for higher-paying roles. 


What Can You Do After HVAC Trade School?

After HVAC-R students finish their trade school, they can start their apprenticeship. After completing their supervised apprenticeship on-the-job training, they can apply for a state license (if needed) and start working as a journeyman HVAC technician based on their area of specialization. Common jobs include:

Certification and Licensure

Whether an HVAC-R worker graduates from a trade school program or not, they may still need to complete an apprenticeship. The length will depend on their educational background and relevant previous work experience. Following their apprenticeship phase, HVAC-R technicians must obtain a license in some states. 

Licensure requirements differ from state to state, but in general, technicians must pass an exam proving they are ready to work on their own at the journeyman level. Each state has its own exam requirements. Check with the applicable state’s examining board before preparing for a test, to ensure you study the right topics. 

In addition to licensure, there are also optional certifications to qualify for certain jobs. These can include:

  • EPA Section 608 certs

How to Get Started on an HVAC Degree

If you’re at least 18, have a high school diploma or a GED, understand basic math, and are interested in pursuing a good-paying career in HVAC-R, then you’re probably ready to apply to a HVAC-R program at a trade school, community college, or university! If you’re not sure if you want to dive in just yet, there are workforce readiness programs that can help you understand a bit more about the HVAC-R career field. 

Not all HVAC techs go to a trade school, but it can help you learn the basics so your apprenticeship experience will go smoother. In fact, having some HVAC-R trade school credits will demonstrate your commitment to the industry, which in turn might help you land a competitive apprenticeship when the time is right. 

You might also want to review apprenticeship requirements to learn what is needed to be competitive. Students who live near a Job Corps training site and meet eligibility requirements may be able to apply for a federally-funded HVAC program!

After you’ve completed your academics, it’s time to apply for a sponsored apprenticeship which will consist of a mix of OJT and technical instruction. The more you learn at school, the shorter the apprenticeship experience should be. 

After a sufficient number of supervised apprenticeship work hours are completed (the number of hours varies by state), you can sign up to take the licensure exam (if needed in your state). After you pass your state’s requirements, you’ll be a journeyman HVAC technician able to work independently. 

From there, additional work experience and optional specialty certifications can qualify you for advancement opportunities, such as moving up to be a master-level technician. Many workers go on to complete an HVAC-R bachelor’s to qualify for better positions. Some launch their own businesses and hire other technicians to work for them!
