FAQs About HVAC Classes

To become a certified technician, you’ll need to complete a formal HVAC training program. This section provides answers to the most frequently asked questions that most people have about this process.

What is HVAC Training?

When you go through an HVAC training program, you’ll be instructed to use the tools and equipment required to service and install heating, ventilation, air conditioning, and refrigeration systems in residential and commercial settings. The two primary methods of getting trained are to either:

  • Complete an apprenticeship, or
  • Graduate from a trade school or technical college


Completing an HVAC apprenticeship is a process that typically lasts between three and five years and requires the trainee to complete at least 2,000 hours of hands-on training. During this time, the apprentice technician is instructed to use tools and equipment from a licensed professional and is also expected to attend at least 144 hours of training in theory.

The general focus of the training received during an apprenticeship falls on the following areas:

  • The role of ventilation, ductwork, insulation, etc. in climate control
  • Installation and maintenance of wiring and other elements of HVAC systems
  • Reading and using blueprints and schematics
  • Strategies and best practices for customer and dealer service

Although individual states may have their requirements as well, the specific apprenticeship program requires trainees to satisfy the following criteria:

  • Be a high school graduate, or hold a GED
  • Be a minimum of 18 years of age at the beginning of the apprenticeship
  • Hold a current driver’s license
  • Pass a drug screening test
  • Be able to pass a basic aptitude test in math and English

Trade Schools and Technical Colleges

An increasingly popular alternative to going through an apprenticeship is taking HVAC classes at trade schools or technical colleges. Most programs last between six months and two years (depending on whether the student is pursuing a diploma, certificate, or associate’s degree) and provide training in all the same areas that one would learn as an apprentice.

Trade School or Apprenticeship?

Whether going through an apprenticeship or enrolling in HVAC classes at your local vocational school often comes down to personal preferences. While the instruction provided through each approach will be very similar, the duration of the program, cost of training, etc., will be quite different. A look at reasons to consider each follows.

3 Reasons to be an HVAC apprentice

The following three things should be considered if you’re interested in becoming an HVAC apprentice.

  • You’ll get paid while you learn your trade
  • You’ll have the opportunity to network with prospective employers
  • You’ll receive daily hands-on training in real work situations

3 Reasons to go to a trade school

You’ll want to think about three things if you’re considering going to a trade school.

  • You can become eligible to work sooner than you would through an apprenticeship
  • You’ll receive more well-rounded training in a wider range of HVAC-related fields
  • Employers are increasingly interested in hiring those who have completed formal training

How Long is HVAC Training?

The duration of your HVAC training will depend on two primary factors. They are:

As stated elsewhere on this page, if you’re planning on completing an internship, you’ll need to plan on dedicating three to five years towards this goal. You’ll be required to complete no less than 2,000 hours of hands-on training under the guidance of a licensed HVAC technician and 144 hours of study in a formal classroom setting.

The amount of time required to complete HVAC programs offered in technical colleges will depend entirely on the type of credential you’re pursuing and whether or not you are a full-time student.

The amount of time required for full-time students to complete each of the following credentials is generally reflected below.

How Much is HVAC School?

The cost of completing your HVAC classes and becoming eligible to take the licensing exam in your state can vary considerably. Of course, the school you choose to attend will have the most significant effect on the cost of your education, but there are other factors to consider. These include:

  • Are you taking online classes or campus-based classes?
  • Are you eligible for financial aid, scholarships, grants, etc.?
  • Which type of credential program are you enrolling in?

Each of these three factors will carry some degree of influence on the cost of your training.
