Classes In An HVAC Training Program

Learn about the different classes in an HVAC training program. While every program will vary slightly and emphasize different components, you will learn foundational skills related to heating, ventilating, and air condition systems. Expect your classes to cover AC and heating systems, electrical theory, computing and more.


From learning how to create an email account and attaching documents to the fundamentals of Microsoft Word, basic computing classes may be a part of your curriculum.

Technical Writing

While it may not seem like HVAC technicians need to write on the job, the opposite is true. You’ll need to prepare HVAC reports and documents with confidence on the daily. Basic technical writing skills covered in class will include reporting, letter writing, memo writing, and technical documentation.

Electrical Theory

You'll learn electrical theory principles such as wiring, motor controls, industry load levels, and characteristics of electrical functions. You will also learn how to use an electrical meter to troubleshoot problems.

Refrigeration Theory

The physics behind refrigeration are covered in this class. Topics will include thermodynamics, pressure, temperature, refrigeration, and more. Along with scientific concepts, you'll learn basic repair techniques, from electric work to piping.

HVAC Safety

Before you can dive into HVAC systems functioning, you must learn safety rules. From OSHA training to instruction in power tools and industry-specific hand tools, you will gain a hands-on understanding of working with HVAC equipment, which is a prerequisite to further work.

Heating Systems

In this class, you'll dive into commercial and residential heating systems, learning about gas and oil furnaces, heat pumps, electric resistance heating, and gas-fired heating systems. Lab work will cover the diagnostics, installation, service, and repair of heating systems.

Air Flow

Problems with air flow tend to occur in internal parts and duct work related to refrigeration, heating, and air conditioning systems. To be able to fix problems, you must learn about air flow, duct-work, and fans.

AC & Refrigeration Systems

This class takes a hands-on approach to troubleshooting and repairing air conditioning and refrigeration systems. With classroom lessons on residential and commercial systems and lab work on service and repair, this class will provide foundational knowledge necessary to work in HVAC.

Sum It Up

The variety of classwork covered at a typical HVAC training school helps you learn as much as possible about the field quickly: You can be completed with training in as few as 6 months! 

The more knowledge you have of the systems and procedures, the more jobs you can take on with confidence after training, and the better you may get paid. In 2019, HVAC technicians made an average annual pay of $51,420, and the top 10% brought in more than $77,920 (bls.gov).
