Online HVAC Courses – Training And Testing

Graduating from online HVAC courses can quickly advance the careers of busy adults. These courses focus on the same employer-demanded skills as their campus-based counterparts, but they offer a level of convenience that cannot be matched.

When enrolling in an online class, most heating and cooling students have at least one of these three goals:

  • Obtain the basic training necessary to enter the HVACR field.
  • Increase knowledge and skills to qualify for career advancement opportunities, more responsibilities, and better wages.

Online courses can benefit men and women of all ages, interests, and experience levels.

Learning Objectives

Employers are currently hiring qualified professionals to work in homes, offices, shopping centers, hotels, medical facilities, processing plants, and more. Access to these jobs starts with a few months of training. Students can choose either HVAC degree programs that last about one year or non-credit, self-paced classes.

Practical Skills

online hvac trainingThe most successful HVACR technicians understand how to work with all types of heating, cooling, and refrigeration units. They understand the differences between models and between brands. Online HVAC courses teach a number of essential skills, including how to:

  • Design and install systems that adhere to manufacturer specifications
  • Understand fossil fuel combustion systems and green energy alternatives
  • Handle refrigerants in compliance with Environmental Protection Agency guidelines
  • Test electrical circuits and measure voltage
  • Measure and correct temperatures and humidity levels
  • Clean coils, fans, registers, and humidifiers
  • Drill and cut metal with the appropriate tools
  • Install and repair motors, compressors, pipes, water supply lines, ducts, and thermostats
  • Communicate with customers, supervisors, and peers
  • Stay safe on the job site

Industry Knowledge

In addition to having hands-on skills, students interested in becoming HVAC technicians must understand a certain amount of theory to make day-to-day decisions. HVAC degree programs provide essential background knowledge, such as:

  • System design
  • Electrical wiring and circuits
  • Refrigeration
  • System charging procedures
  • Superheating and sub-cooling
  • Radiation
  • Conduction
  • Convection
  • Heat pump operation
  • Compressor operation
  • Humidity and relative humidity

Because online HVAC training can be completed quickly, instructors focus on applied theory. In order words, service technicians only learn the essentials that they will actually use in residential and light commercial settings.


Online HVAC schools help students prepare for licenses and certificates that give an edge in the job market. In today's competitive economy, a certification from one of these agencies can convince an employer to hire one person over another:

  • NATE, North American Technician Excellence
  • AHRI, Air Conditioning, Heating, and Refrigeration Institute
  • HVAC Excellence
  • EPA Section 608 Refrigerant Testing

Future HVAC technicians must keep in mind that some certifying agencies and state licensing commissions require hours of hands-on training and work experience. Students should check with each agency for qualifications.

Course Structure

online hvac coursesDistance education brings a number of advantages. When students take cooling and heating courses online, they can structure their days around working hours, family commitments, and social obligations. Convenience and access are two major benefits of going online for HVAC education.

Convenient Scheduling

Online HVAC courses still deliver all of the traditional program benefits, such as full-time or part-time attendance, interaction with instructors who have industry experience, and preparation for industrial certification and licensing. Many programs let students work at their own pace, so they do not have to commit to a several hours of study per day. Individuals can obtain the knowledge they need as quickly or slowly as makes sense for their circumstances.

In addition to online-only coursework, some HVAC schools offer combination online/on-campus programs. Students take the theory portion of their training online and then practice on machinery in the classroom.

Access for Everyone

HVAC training is no longer limited to men and women who live in a large city or can commute hours to campus. Distance education gives access to everyone who meets the basic system requirements.

Most HVAC courses are available on PC or Mac with any of the major web browsers. Some schools even offer training modules for iPhone, iPad, Android, Kindle, or other devices. Students who enroll in a qualified program can take control of their HVAC careers today.
