HVAC training in Oklahoma

29 HVAC training programs with costs, results and funding that can make them free

26 schools offer these HVAC programs, and Oklahoma has approved every one for workforce funding. Each shows its price if you pay yourself and how past students did.

HVAC technicians work on heating, ventilation, cooling and refrigeration systems. Most train in a certificate program, which usually includes the EPA refrigerant exam that nearly all technicians must pass, and some states also require a license.1 In Oklahoma, 23 of the 29 programs take students without a high school diploma, and 6 are taught partly or fully online.

Source: US Department of Labor, program year 2024 (July 2024 to June 2025). Only programs approved for workforce funding are listed; other schools in Oklahoma may also offer HVAC training. How these figures are made

The year of these Oklahoma figures is uncertain. Oklahoma has not sent its program year 2024 data to the federal site, so check with the school and an American Job Center that the program is still approved and the funding terms still apply. We will update this page when that data is out. More on this

How to pay for HVAC training in Oklahoma

Workforce funding can pay for HVAC training in Oklahoma

Every program on this page is approved for public workforce funding, the Workforce Innovation and Opportunity Act. It can pay for training for eligible adults, people who lost their job and young people.2People on public assistance, with a low income or lacking basic skills come first, and veterans have priority.3

Ask at an American Job Center

Eligibility rules apply, and services vary from state to state. Your local American Job Center can tell you whether you qualify. The Department of Labor's page links to the center finder, or call 1-877-US-2JOBS (1-877-872-5627).4

Financial aid and grants for HVAC training

Most students can get federal student aid for college, career school or trade school. A Federal Pell Grant, unlike a loan, usually doesn't have to be repaid. Ask the school whether its program qualifies.56

GI Bill for HVAC training

Veterans, service members and qualified dependents can use GI Bill benefits for non-college training programs.7

The program list does not show which programs accept these. Ask the school.

Where the Oklahoma HVAC program numbers come from

Which Oklahoma HVAC programs are on this list?

These are the HVAC programs Oklahoma approved for public workforce funding (the Workforce Innovation and Opportunity Act), as reported to the US Department of Labor for program year 2024 (July 2024 to June 2025). The list covers programs approved as of June 30, 2025. Schools that never applied for approval are missing, so this is a part of what Oklahoma offers.

How Oklahoma HVAC program prices are reported

The price is tuition and required fees for someone paying without workforce funding, as the school reported it. Prices under $100 are treated as not reported, because the file holds many blanks entered as $0. Check the current price with the school.

What the graduate results of these programs measure

The figures at the top of this page are the middle program among those that report results: half did better, half did worse. Results describe students who left each program in recent years: the share who finished, the share working in the second quarter after leaving, and the middle earnings of those working in that quarter. States report earnings for that one quarter because they take them from the wage reports employers file every three months. The yearly figure here is that quarter times four, rounded to the nearest $100: an estimate, and an early one, since it is measured about half a year after training. The quarter as reported is under "More details" on each program. Results are withheld for small programs, and they describe past students, so they are no guarantee.

Why do some HVAC programs say "Not reported"?

Where a school or the state left a field empty, or the Department of Labor withheld it, the page says "Not reported". Nothing here is estimated to fill a gap.

Why the kind of school is left off each program

The file also records whether a school is public, private or nonprofit, but those entries are wrong too often to print next to a school's name, so this page leaves them out.

How reliable are the Oklahoma figures?

The US Department of Labor's own results site says Oklahoma has not yet sent its data for program year 2024.8 So we cannot say which year these figures describe; they may be older. Before you enroll, check with the school and your local American Job Center that the program is still approved and that the funding terms still apply. We will update these pages when the federal site publishes the 2024 data for Oklahoma. We leave out the share working 6 months later for Oklahoma: far more of its programs report exactly 100% than in other states.
