What is HVAC and What Does It Stand For?

Heating, Ventilation, and Air Conditioning are collectively referred to as HVAC, and the professionals who work in this industry are called HVAC technicians or HVAC tech. Sometimes, the installation and upkeep of refrigeration units are also taken care of by these pros, in which case they are called HVACR or HVAC/R technicians.

What Does an HVAC Technician Do?

Typically, an HVAC technician is responsible for: 


Testing various types of units, components, and electrical circuits to ensure they are fit for installation in a residential or commercial setting. 


Installing climate control systems, heating and air conditioning systems, and refrigeration systems across residential and commercial projects. 

Maintenance and Servicing 

Ensuring the frequent maintenance and servicing of the installed HVACR units by visiting the sites. 

Troubleshooting and Repair Work 

Answering customer calls, identifying snags or glitches in the HVAC equipment, and resolving common HVAC issues. 


Gauging the need to replace any HVAC parts or convincing the customer to buy a new HVAC system.

Job Description

As mentioned above, HVAC tech or HVAC service technicians work to install, maintain, repair, or replace air conditioners, climate control systems, heating equipment, ventilation units, refrigeration equipment, and more.

Here’s a look at the various responsibilities of an HVAC technician: 

  • Reading blueprints and HVAC equipment specifications
  • Assembling and installing HVAC/R units in residential or commercial buildings 
  • Cutting or drilling holes in building structures 
  • Installing solar panels, thermostats, humidistats, and timers
  • Connecting HVAC systems to electrical, water, and fuel sources
  • Ensuring that the HVAC units are working perfectly
  • Testing HVAC components and systems according to the manufacturer’s specifications
  • Testing piping or tubing joints for leakages

How to Become an HVAC Technician?

HVAC technicians are in great demand across the globe, thanks to the nature of the job. Because of the very specific skills and competencies that professionals in this domain require, AI and bots are less likely to replace HVAC tech jobs. 

With steady job growth predicted in the foreseeable future for HVAC technicians, it is a good time to enter this industry with the right set of skills and qualifications. There are three primary ways to become qualified for the job. 


While you might come across HVAC technicians who don’t have a college degree, that is not necessarily the case with all technicians in this sector. Yes, it is possible to start without an HVAC degree, but that isn’t the ideal route to becoming a professional HVAC service technician.

Like any other profession, we recommend signing up for a full-time HVAC training program to learn the ropes. Education is an essential part of learning the fundamentals and nuances of refrigeration, heating, ventilation, and air conditioning.

Getting an associate degree in heating, ventilation, air conditioning, and refrigeration gives you a solid foundation in the subject. You can gain important theoretical knowledge and practical training to develop the critical skills you will need as a full-time HVAC technician.

The associate in science degree in RACH helps students understand the nitty-gritty of the subject and gain valuable practical experience in the labs. Formal training will enable you to become an entry-to-industry level tech with the perfect blend of scientific know-how and technical expertise.

And while the degree itself is a solid way to begin your journey as an HVAC service technician, employers sometimes prefer certified technicians. 

Apart from learning the theory and getting hands-on training in the lab, some trade school training programs, like the one New England Institute of Technology offers, also prepare you for various HVAC certifications. Some employers or states require you to possess certifications like the North American Technical Excellence (popularly referred to as NATE).

HVAC Apprenticeships

HVAC Apprenticeship

An apprenticeship is also a great way to learn on the job and land rewarding gigs in the HVAC industry. Various local associations (the Air Conditioning Contractors of America or the Associated Builders and Contractors, for instance) offer HVAC apprenticeship program opportunities. These programs could last anywhere between three to five years. 

Alternatively, you can find journeymen and apply for an interview with them. In some cases, it might be an unpaid internship in the beginning. However, if you prove your worth during the trial period, your employer will start paying you sooner rather than later.

HVAC Licensing Requirements

While a license isn’t mandatory, it is a strong asset to possess. Not all US states need you to have an HVAC license, but it is best to make sure which ones require you to pass a written exam.

Being a licensed HVAC technician has its own set of perks. For starters, you will invariably have a more evolved skill set compared to unlicensed HVAC techs. Moreover, it will hold you in good stead when seeking employment.

The Pros and Cons of an HVAC Career 

HVAC tech is a fantastic career choice from a long-term perspective, but you should know its advantages and disadvantages before you take the plunge.
