Heating Refrigeration and Air Conditioning Technology Schools and Programs in The United States

Heating Refrigeration and Air Conditioning Technology Studies in The United States

Heating, refrigeration and air conditioning technology, usually shortened to HVAC or HVACR, trains technicians to install, maintain and repair the systems that heat, cool and ventilate buildings and keep food and medicines cold. Students learn refrigeration theory, electrical controls, airflow and ductwork, troubleshooting and safe handling of refrigerants. In the United States it is a hands-on, career-focused subject taught mainly at community and technical colleges. SpainExchange lists 30 colleges in the United States that teach it.

How the training is organised

According to the Bureau of Labor Statistics (BLS), HVAC technicians typically train at technical and trade schools or community colleges. These programmes generally last from 6 months to 2 years and lead to a certificate or an associate degree. Some technicians train instead through an apprenticeship, which usually lasts several years and combines paid on-the-job training with technical instruction each year.

The college programmes on our list show the typical structure. At Hudson Valley Community College in Troy, New York, the Heating/Air Conditioning/Refrigeration Technical Services degree (an Associate in Occupational Studies) covers the design, installation and service of commercial and residential systems, with classroom and laboratory teaching in two dedicated HVAC labs. At Bismarck State College in North Dakota, the HVAC programme is offered from fall 2026 only as a certificate or an Associate in Applied Science (AAS); teaching covers HVAC components and systems, troubleshooting, domestic and light commercial refrigeration and sheet metal. Credits from the Bismarck State AAS can stack into a Bachelor of Applied Science in Operations Management, one route for technicians who later want a management role.

Certification and licensing

Certification is a central part of the training. Under Section 608 of the Clean Air Act, the Environmental Protection Agency (EPA) requires technicians who maintain, service, repair or dispose of equipment that could release ozone-depleting refrigerants to be certified. The exam has a core section and three types: Type 1 for small appliances, Type 2 for high-pressure and Type 3 for low-pressure equipment. The BLS notes that the exam is typically included in a postsecondary HVACR programme; Bismarck State, for example, has its students take the EPA refrigerant exam. Some states and localities also require HVAC technicians to be licensed, so rules depend on where you plan to work.

Admission, visa and costs

Teaching is in English, and colleges usually ask international applicants for proof of English proficiency. The visa depends on the programme: the F visa is for study at an accredited college or university, while the M visa is for non-academic or vocational study or training. Once accepted by a school certified by the Student and Exchange Visitor Program (SEVP), the international student office issues the form used in the visa application. Check that the specific programme can enrol international students, and note that places can be limited: at Bismarck State, admission is in the fall and students are encouraged to apply early.

Community colleges are the cheapest route into the field. According to the National Center for Education Statistics (NCES), average tuition and fees at public 2-year institutions were $4,000 in 2022-23. That figure is the in-district or in-state rate, so ask each college what it charges students from outside the state or country.

Where to study HVAC technology

Programmes are spread across the country, usually at public community and technical colleges that train for the regional job market. Examples from our list include Hudson Valley Community College in Troy (New York), Bismarck State College (North Dakota), Linn-Benton Community College in Albany (Oregon), Greenville Technical College (South Carolina), Virginia Western Community College in Roanoke, Delaware Technical & Community College, Lansing Community College (Michigan) and Erie Community College in Williamsville (New York).

Careers

Graduates work as installers and service technicians for heating and cooling contractors, in building maintenance, in commercial refrigeration and in equipment sales. Hudson Valley Community College lists jobs as installers and service technicians, HVAC/R sales representatives and in research and testing. According to the BLS, the median annual wage for HVAC mechanics and installers was $61,010 in May 2025. Employment is projected to grow 11 percent from 2025 to 2035, much faster than the average, with about 40,600 openings a year.

Frequently asked questions

How long does HVAC training take in the United States?

College programmes generally last from 6 months to 2 years and lead to a certificate or an associate degree. Apprenticeships usually last several years.

Do HVAC technicians need a certification?

Yes, in most cases. The EPA requires technicians who work with equipment that could release ozone-depleting refrigerants to hold Section 608 certification, and some states and localities also require a licence.

Which visa do I need for an HVAC programme?

The M visa covers non-academic or vocational study or training, while the F visa covers study at an accredited college or university. The college's international student office can confirm which applies to its programme.

Is HVAC a good career in the United States?

Demand is strong. The BLS projects employment of HVAC mechanics and installers to grow 11 percent from 2025 to 2035, much faster than the average for all occupations.
