HVAC technicians are essential to the U.S. economy. From keeping residences comfortable in extreme weather to providing the technical knowledge required to refrigerate warehouses, keep food fresh, and even keep the air in hospitals clean and circulating, HVAC technicians excel in many different capacities, often working behind the scenes.
Often mechanically inclined problem-solvers by nature, HVAC technicians must train for the role via a lengthy apprenticeship (four years is the norm) or by enrolling in a formal HVAC education program. Although aspiring technicians may enroll in a four-year bachelor’s degree program, those are relatively uncommon and perhaps best suited to those interested in learning as much about the business side of an HVAC operation as about the more technical, applied side.
The two-year associate degree can be an attractive proposition for students who may not want to, or be able to, attend a four-year program, but who still want to complete a rigorous technically oriented HVAC education. Earning an Associate of Applied Science degree is a great launching pad for an HVAC career because it shows dedication and signifies a thorough basic technical knowledge of HVAC systems.
An HVAC associate degree, such as those offered by the schools on this list, includes instruction in more than just the fundamentals of HVAC systems. An AAS degree in HVAC requires courses in various topics, from communication to mathematics to liberal arts. This breadth of knowledge will be invaluable in a competitive job market.
Many HVAC students have no problem finding employment quickly in this profession, which is expected to grow 6 percent from 2022 to 2032, which is faster than the average for all occupations (3 percent) according to the Bureau of Labor Statistics (2024).
The schools on this list each offer an associate degree in HVAC technology or a more specialized degree such as refrigeration and have all been accredited by recognized accreditation organizations. Many even have the option of transferring earned credits to a four-year school upon graduation for even more career and earning opportunities.
