What is an HVAC Technician?

Heating, air conditioning, and refrigeration mechanics and installers (HVACR technicians) work on heating, ventilation, cooling, and refrigeration systems that control temperature and air quality in buildings. Heating, air conditioning, and refrigeration mechanics and installers typically do the following:

  • Install, clean, and maintain HVACR systems
  • Install electrical components and wiring
  • Inspect and test HVACR systems and components
  • Discuss system malfunctions with customers
  • Repair or replace worn or defective parts
  • Recommend maintenance to improve system performance
  • Keep records of work performed

Heating and air conditioning systems control the temperature, humidity, and overall air quality in homes, businesses, and other buildings. By providing a climate-controlled environment, refrigeration systems make it possible to store and transport food, medicine, and other perishable items.

When installing or repairing air conditioning and refrigeration systems, technicians follow government regulations regarding the conservation, recovery, and recycling of refrigerants. The regulations include the proper handling and disposal of fluids and pressurized gases.

HVACR technicians specialize in one or more specific aspects of HVACR, such as radiant heating systems, solar panels, testing, and balancing, or commercial refrigeration. They also maintain heating and cooling systems through services that include system inspection, duct cleaning, filter replacement, and checking refrigerant levels.

Related professions include sheet metal workers, electrical work by electricians, and pipework by plumbers, pipefitters, and steamfitters. Boiler systems are sometimes installed by a boilermaker.

How to become an HVAC Technician?

Because HVACR systems have become increasingly complex, employers generally prefer applicants with postsecondary education or those who have completed an apprenticeship. Some states and localities may require technicians to be licensed. Workers may need to pass a background check prior to being hired.

Many HVACR technicians receive postsecondary instruction from technical and trade schools or community colleges that offer programs in heating, air conditioning, and refrigeration. These programs generally last from 6 months to 2 years and lead to a certificate or an associate’s degree.

High school students should take courses in vocational education, math, and physics. Knowledge of plumbing or electrical work and a basic understanding of electronics is also helpful.

Some technicians receive their training through an apprenticeship lasting 3 to 5 years. Several groups, including unions and contractor associations, sponsor apprenticeship programs.

The U.S. Environmental Protection Agency (EPA) requires all technicians who buy, handle or work with refrigerants to be certified in proper refrigerant handling. Many trade schools, unions, and employer associations offer training programs designed to prepare students for the HVACR requirements include:

  • Customer-service skills
  • Detail oriented
  • Math skills
  • Mechanical skills
  • Physical stamina
  • Physical strength
  • Time-management skills
  • Troubleshooting skills
