Oklahoma HVAC Training Schools & Certification

No one can accuse Oklahoma of having a boring climate. The weather cycles include a varied mix of long, hot summers; short, cold winters; high humidity; flash floods; droughts; tornadoes; and thunderstorms. It goes without saying that Oklahomans rely on heating, venting, and air conditioning (HVAC) to stay comfortable indoors throughout the year.

Numerous national HVAC and refrigeration (HVAC/R) associations provide support to technicians, and three have chapters in Oklahoma: the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE), the Mechanical – Electrical – Plumbing Contractors – Oklahoma (MEPO), and the Plumbing-Heating-Cooling Contractors Association (PHCCA). Industry organizations such as these provide resources to help maintain professional standards, keep workers in the know on legislative changes, provide continuing education, and offer discounts on common expenses in the profession.

According to the Bureau of Labor Statistics (BLS May 2024), 4,820 Oklahomans were employed as HVAC installers, mechanical, and maintenance workers. In general, HVAC workers use their skills to install, maintain, and repair equipment and systems that control air quality and temperature. One job may require putting wiring and piping for an installation. The next job might require testing components and circuitry. Technicians need to be familiar with how components such as motors, belts, fans, filters, and valves function within a complete system.

They install and service equipment, including boilers, compressors, heat pumps, humidifiers, economizers, and water pumps in various kinds of buildings. Skills include reading blueprints, computing heat load and loss calculations, and calibrating controls. All workers are responsible for keeping their credentials current, traveling to job sites, and making sure customers receive detailed service records. An important part of HVAC service is helping customers understand and practice energy conservation.

This guide explores the thriving HVAC industry in the Sooner State, including discussions of salary prospects and accredited training programs.

Occupational Demand for HVAC Technicians in Oklahoma

The demand for HVAC technicians nationwide continues to grow. According to the BLS (2025), the number of openings in this field is expected to grow 8 percent nationwide between 2024 and 2034—much faster growth than the U.S. average across all occupations (3 percent). And Oklahoma is keeping pace with the national demand for technicians. In fact, Projections Central (2026) predicted a 7.7 percent statewide increase in HVAC jobs for the decade ending in 2032.

Several factors in OK contribute to the growth of the HVAC industry:

Construction of new commercial buildings and residences
The complexity of climate control systems
The contemporary emphasis on energy efficiency and reducing pollution
Replacing, retrofitting, or upgrading older systems

Some HVAC equipment is located outdoors. Adverse weather conditions don’t stop the need for repairs or maintenance. Indoor work can be equally uncomfortable when the system has stopped working, creating either a very hot or freezing environment until the job is completed. Technicians may find themselves working in small or cramped areas.

It’s worth noting that HVAC workers have a relatively high rate of injury, including electrical shocks and muscle strains related to moving heavy equipment. They also work with toxic chemicals. That said, with proper training in safety protocols, these risks can generally be kept at bay.

The BLS (2025) reported that approximately 5 percent of HVAC/R technicians were self-employed across the country, and 70 percent were employed by plumbing, heating, and air conditioning contractors. The remaining workers were employed by schools or retail and wholesale organizations. Most of the technicians worked full-time. Depending on peak seasons, OK-based workers may work evenings, weekends, and other overtime hours.

HVAC Salaries in Oklahoma

The BLS (May 2024) reported that nationally HVAC/R mechanics and installers receive a median salary of $59,810 annually. Oklahoma HVAC/R technicians receive slightly less, as their annual median wage was $50,920.

That said, it is important to add that the cost of living in Oklahoma is significantly more affordable than a majority of U.S. states. As proof of point, the Missouri Economic Research and Information Center (MERIC 2026) reported that Oklahoma had the lowest cost of living in the United States. This low cost of living means that even average salaries will go farther in Oklahoma than in other states.

In more detail, here were the annual wage percentiles for HVAC professionals across the country and across Oklahoma (BLS May 2024)—the latest data available as of February 2026:

	United States	Oklahoma
Number of HVAC professionals employed	396,870	4,280
Annual mean wagee	$62,690	$55,400
10th percentile	$39,130	$35,610
25th percentile	$47,850	$38,540
50th percentile (median)	$59,810	$50,920
75th percentile	$74,820	$63,440
90th percentile	$91,020	$79,580

The national figures were slightly different according to another source of data, PayScale (2025), which relies on self-reported salaries. Among the HVAC workers reporting their annual salaries, Payscale found these percentiles:

10th percentile: $34,000
50th percentile (median): $55,839
90th percentile: $86,000

HVAC Apprenticeships in Oklahoma

Although some HVAC companies in Oklahoma hire workers with no experience or training, workers who have served an apprenticeship or attended a school are usually hired first. Trained workers also typically start at higher wages, advance quicker, and earn more over the life of their careers.

An apprenticeship is a paid position that combines on-the-job training with classroom instruction. It usually takes four to five years to complete. Apprentices also attend school for a specified number of hours each year.

As of February 2026, there are active registered apprenticeship programs located in cities throughout Oklahoma. There’s more information at the Oklahoma Office of Workforce Development.

Accredited HVAC Schools in Oklahoma

Individuals seeking coursework should make sure that the school they choose is accredited. “The goal of accreditation is to ensure that education provided by institutions of higher education meets acceptable levels of quality,” according to the Department of Education. Various agencies determine whether schools have met the applicable guidelines.

Two main organizations evaluate and accredit HVAC programs: HVAC Excellence and the Partnership for Air-Conditioning, Heating, Refrigeration Accreditation (PAHRA). As of early 2026, nine Oklahoma schools have been awarded accreditation by PAHRA, and six have been accredited by HVAC Excellence, with some schools accredited by both organizations.

HVAC Certification & Licensing in Oklahoma

Federal law requires all HVAC technicians who work with refrigerants to obtain Environmental Protection Agency (EPA) Section 608 certification. Certification requires passing an exam on the safe handling of refrigerants. Four levels of certifications are available based on the size and type of equipment. The universal certification allows technicians to work on all types.

Technicians may obtain additional training and certifications from industry organizations. These include, but aren’t limited to:

Refrigeration Service Engineers Society (RSES)
North American Technician Excellence (NATE)
HVAC Excellence

Check out details on national credentialing on the guide to HVAC certifications.

Additionally, the State of Oklahoma requires apprentices to register. There is no fee to register. Journey-level and contractors must be licensed. There are several classifications, based on the size and type of systems worked on. Each classification has education, experience, and testing requirements. Please note that fees and qualifications vary.

Lastly, cities may have separate permitting or credentialing requirements for this occupation. To ensure compliance with the law, all HVAC workers in Oklahoma are encouraged to contact their city offices before beginning any projects.
