15 Top AC Technician Schools

Connect With HVAC Schools

Air conditioning technicians are in high demand. Virtually every new building needs a trained technician to install its air conditioning system, to say nothing of the need for regular maintenance and repair. Certainly air conditioning (AC) is about providing a level of comfort, particularly in hot summer months, but it also helps keep hospitals safe, groceries fresh, and skating rinks cold. So, air conditioning can be vital, and keeping AC systems running smoothly requires an understanding of sophisticated temperature control systems that are growing progressively more computerized and in many cases “green”. Understanding how to install and maintain such systems now requires the completion of either an apprenticeship program, which commonly takes 4 years, or a certificate or degree program, typically a 2-year associate degree program.

It is important that new AC technicians find a school that offers more than just a convenient location. Some schools are simply better equipped to provide the kind of job training necessary to secure employment in a competitive market. The following AC technician schools have proven that they are dedicated to training students through to professional certification and employment, and have third-party accreditation and unique program offerings. Whether you want to learn refrigeration techniques at AVTEC in Alaska or air conditioning theory at LATTC in Los Angeles, the right school is out there to help you jump-start a new HVAC career today.

The courses offered also prepare students, who must have at least a GED to attend, for certifications including the EPA refrigerant handler certification, Air Conditioning ER Certification, and Basic First Aid Certification.


The high demand for AC technicians means that there is also a high demand for training programs. The right school for any individual will be the one that best suits their needs in terms of programs but also tuition, location, and other personal factors. That said, the AC technician schools on this list were chosen for a few specific reasons including accreditation, a focus on air conditioning technology, and the available of AC-specific certifications.

  1. Accreditation All institutions of higher learning should be accredited in some way or another. For AC tech schools, there are a number of accrediting bodies that were evaluated for this list. HVAC Excellence and the Partnership for Air Conditioning, Heating, Refrigeration Accreditation were both considered as they are the main accrediting bodies for HVAC training programs. Some schools on this list are instead accredited by nationally recognized higher education accrediting bodies such as the Council on Occupational Education.

  2. Air Conditioning Technology Focus While it is easy to find schools that offer degrees and certificates with an HVAC focus, it is more difficult to find those that offer a specific AC technician program. The majority of the programs on this list offer diplomas or certificates with an emphasis solely on air conditioning and refrigeration, for those students who want to devote their time and resources to this side of the HVAC business.

  3. EPA Certification Training Any AC technician school that truly prepares its students for work in the field must include refrigerant handling EPA certification training in their program. These air conditioning technology programs offer training and testing for EPA certification so that students are ready to work in the field safely upon graduation.
