What Is A HVAC Tech?

Any building you walk into will have some type of heating, ventilation, and air conditioning units. These units require set up, maintenance, repair, and proper cleaning to ensure that they work to the highest degree. HVAC technicians are specially trained to work on these systems. But what exactly is an HVAC Technician, and what do they do? 


HVAC is short for heating, ventilation, and air conditioning. HVAC is also referred to as HVAC/R, which includes refrigeration. In order to start the education and training program, a person must be at least 18 years or old and have a high school diploma or equivalent. A potential student must also pass a simple math test, have a valid driver's license, and pass a substance abuse screening test. 

The educational part of the program lasts between 6 months to 2 years, depending on the school you choose to attend. Classes in the program will include: 

  • Gas heating
  • Air conditioning, electric heat, and heat pumps
  • Refrigeration systems
  • Commercial controls and applications
  • Installation and troubleshooting systems

A future HVAC tech can also start an apprenticeship program that lasts between 3-5 years. Depending on the state, a person might also need to get a license as well. 

What Does the Job Entail?

An HVAC technician has a lot of responsibilities when it comes to each part of their title. They have to understand the unit, where it is located and how it flows from inside and outside of the building, the electrical information, and much more.
