If you're looking for job that won't go out of style, consider a career in HVAC, also known as HVACR. Standing for heating, ventilation, air conditioning and refrigeration, workers in this field keep both residential and commercial buildings feeling comfortable, among other goals. Since virtually all buildings have environmental controls, HVAC technicians will likely always be in demand.

In the HVAC trade schools, HVAC technicians might do any of the following:

  • Install new HVACR systems, including electrical components
  • Test new and existing HVACR systems to ensure proper working condition
  • Repair or replace defective units
  • Recommend system upgrades and maintenance
  • Maintain service records for clients

HVAC Specializations

Students in HVAC programs are taught core fundamentals of the industry, but they may also choose a specialized area for professional development. An HVAC training school can help prepare workers to specialize in the following areas among others:

  • Heating: Technicians who specialize in heating install, repair and maintain everything from simple furnaces to complex multi-load, multi-temperature systems.
  • Cooling: Cooling technicians may service residential air conditioners as well as commercial refrigeration units.
  • Alternative energy: Some technicians focus exclusively on systems that use alternative power sources such as solar panels.
  • Repair: Those who specialize in repair only work on existing systems rather than installing new ones.

How to Become an HVAC Technician

Many people go to an HVAC trade school or complete a HVAC apprenticeship program to become a technician. Here's what you might need to do:

  • Earn a high school diploma or equivalent.
  • Enroll in an HVAC training program, whether it is campus based or with online components.
  • Apply for positions in the HVAC workforce. Opportunities often come up through your school's resources, so be active in your search for positions while in school.

HVAC Apprenticeships

An HVAC apprenticeship program is another way to prepare for a career as a technician. These programs may last 2-5 years and combine on-the-job training with classroom instruction. Community colleges and technical schools offer apprenticeship programs as do some unions and trade groups. Partnering businesses sponsor apprentices who are paid for their work during the program.

HVAC Certifications

HVAC certifications are the credentials need to complete before starting the actual job.Any HVAC tech who works with refrigerants must be certified by the U.S. Environmental Protection Agency. Known as Section 608 certification, all applicants must pass a core certification exam before they can apply for one of four credentialing levels.

  • Type I - Designed for technicians that service small appliances
  • Type II - Designed for technicians who service high-pressure appliances
  • Type III - Designed for technicians who service low-pressure appliances
  • Universal - Designed for technicians who pass the core exam and other three parts of the Section 608 certification examination

There are also voluntary certification programs offered by industry groups. The North American Technician Excellence (NATE) certification is considered by many to be the gold standard in the field. Gaining NATE certification demonstrates real-world, fundamental knowledge of heating, ventilation and air conditioning systems. Its certifications fall into four categories:

  • Ready-to-Work Certificate for entry-level technicians with little to no education or experience.
  • HVAC Support Technician Certificate for those with 6-12 months of work experience.
  • Core and Specialty Certifications in more than a dozen areas such as air distribution and oil heating for those with at least two years of work experience.
  • Senior Level Efficiency Analyst Certification which is the highest level of certification offered by NATE.

As for how to get HVAC certified, you'll need to have the proper level of experience and pass a certification exam. The Senior Level Efficiency Analyst Certification is only available to those who already have at least one heating and one cooling certification from NATE.

The HVAC Excellence certification program is another well-known option for technicians, and industry groups such as the Air-Conditioning, Heating & Refrigeration Institute offer their own certification programs as well.

Career Advancement for HVAC Technicians

Expanding skills is a top way for HVAC technicians to advance their careers. Earning specialty certifications or working with new technologies, such as green energy sources, may open up new job opportunities. Another option for career advancement is to become an instructor at a HVAC school.
