The quality of the air inside our homes and places of work depends on the expert skill of HVAC (sometimes also called HVACR) technicians. Heating, Ventilation, Air Conditioning, and Refrigeration mechanics and installers are in demand across the residential and commercial sectors. According to the U.S. Bureau of Labor Statistics, job growth in this field is expected to increase over the next 10 years, with workers earning an average of $48,730 per year.

What Do HVAC Technicians Do?

HVAC techs are responsible for installing and maintaining heating, cooling, and refrigeration systems in homes and commercial spaces. They have expertise in installing electrical components and know the methods needed to inspect HVACR systems and spot malfunctions. Technicians must have a knowledge of government regulations concerning HVACR systems, such as proper handling of refrigerants.

How Do You Become A HVAC Technician?

Most technicians receive some type of education in order to become certified to work in the field. Community colleges, trade, or technical schools offer instruction ranging from 6 months for a professional certificate up to 2 years for an associate’s degree. At entry-level, a new tech may be expected to work with someone with more experience before being allowed to work alone. For this reason, some seek out apprenticeship programs, which last 3 to 5 years.
