HVAC Schools in South Carolina

Few residents of South Carolina (SC) would be willing to face the hot, humid summers without the protection of an air conditioner. Most homes and other buildings throughout the Palmetto State are equipped with climate-control systems to help keep residents comfortable throughout the year. As a result, the state is home to many jobs in the heating, ventilation, and air conditioning (HVAC) industry.

In addition to a relatively robust job market in South Carolina, HVAC technicians can enjoy the support of many unions and professional organizations statewide, including the UA Local 421, which is headquartered in Charleston, SC. HVAC workers also have the option of joining the Mechanical Contractors Association of South Carolina, which supports HVAC technicians, as well as numerous other professionals in the mechanical trades. This organization offers a calendar of events throughout the year, a scholarship for HVAC training programs, and other benefits to help members succeed in the industry.

In reality, a job as an HVAC technician in South Carolina can be truly rewarding for those interested in this type of work. However, before starting any new career, it is important to understand the scope of the profession. Here is an overview of an HVAC mechanic or installer’s typical daily responsibilities in SC:

Ensure HVAC equipment is properly calibrated
Conduct calculations on equipment
Keep proper records
Interpret blueprints
Ensure equipment and work are in compliance with the law
Move between various work sites
Offer education to customers on energy use and conservation
Maintain appropriate licensure and permits

Furthermore, anyone who works with refrigerants in South Carolina must maintain active EPA Section 608 Certification.

Ultimately, an expanding HVAC industry in South Carolina is an invitation for those interested in this line of work. This guide includes an overview of the HVAC industry in SC, as well as the salary expectations, various training programs, and licensure requirements for technicians in the state.

Occupational Demand for HVAC Technicians in South Carolina

The Bureau of Labor Statistics (2023) reported that there were 397,450 HVAC technicians working across the country in May 2023. The BLS (2024) anticipated that the industry would grow 9 percent between 2023 and 2033, which is more than twice as fast as the average for all occupations (4 percent).

Fortunately for aspiring HVAC technicians in South Carolina, there’s also evidence that SC is predicted to need new technicians at a fast rate. Projections Central (2024)—a data organization partnered with the US Department of Labor—reported that there would be a 7.7 percent increase in HVAC positions across SC between 2022 and 2032.

Although there is no single driving factor behind this rapid growth in opportunities, many reasons should be highlighted. For one, HVAC systems require routine maintenance by skilled technicians and must generally be replaced entirely every 10 to 15 years.

In addition, the laws and regulations governing the HVAC industry are constantly in flux; this means that customers must utilize the services of HVAC professionals to ensure their systems comply with the law. Finally, nearly all new buildings in South Carolina will likely be erected with some type of climate-control system; here, skilled HVAC installers will be needed for the original planning and implementation.

There is perhaps no greater proof of the thriving demand for HVAC technicians in South Carolina than online job boards. For example, searching for available HVAC positions in South Carolina on Indeed (Dec. 2024) brought up 300+ results, with companies including Commercial Air Condition Service Inc, Long Heating & Air Inc, Refrigeration Heroes, and Advanced Climate Control LLC.

A similar search on Monster (Dec. 2024) provided several results with organizations including Innova Solutions, CoolSys, Cargill, and Johnson Controls.

HVAC Worker Salary in South Carolina

According to the Bureau of Labor Statistics (BLS May 2023), HVAC mechanics and installers enjoy fairly comfortable wages, particularly considering that the occupation generally requires only six months to two years of postsecondary education.

Among the 397,450 HVAC workers around the US, the BLS found an average annual salary of $59,620 Wages for HVAC professionals in South Carolina were a bit lower, with the average worker earning just $52,240. In more detailed terms, here were the salary percentiles in this occupation in the US as compared to South Carolina:

	United States	South Carolina
Number of HVAC professionals employed	397,450	6,360
Annual mean wage	$59,620	$52,240
10th percentile	$37,270	$36,300
25th percentile	$46,550	$44,790
50th percentile (median)	$57,300	$49,930
75th percentile	$71,120	$60,460
90th percentile	$84,250	$68,530

The national figures were slightly different according to another source of data, PayScale (Dec. 2024), which relies on self-reported salaries. Among the HVAC workers reporting their annual salaries, Payscale found these percentiles:

10th percentile: $36,000
50th percentile (median): $55,431
90th percentile: $84,000

As noted above, the average salary for HVAC workers in South Carolina is somewhat lower than that of the rest of the nation. As with any salary projections, considering the cost of living is also important. As such, the Missouri Economic Research and Information Center (MERIC 2024) found that SC was the 23rd most affordable state, ranking it almost right in the middle. For HVAC technicians, this means lower-than-average salaries will not go as far as they would in some lower-cost states nearby.

HVAC Apprenticeships in South Carolina

Before searching for work in the field, many aspiring HVAC technicians choose to complete a training program to obtain the necessary skills and knowledge to succeed. This generally takes the form of an apprenticeship, formal degree, or certificate program, although other options are available.

Currently, the Plumbers & Pipefitters Local Union 421 in multiple cities offers an apprenticeship for those interested in a new HVAC career. This program lasts for five years and requires participants to complete many hours of on-the-job training and classroom education. During the program, apprentices earn a wage that is calculated based on the compensation of the supervising journeyman and are also eligible for raises periodically.

Accredited HVAC Schools in South Carolina

Anyone looking to complete HVAC education in South Carolina should also understand that many aspiring technicians choose to enroll in accredited programs, which often last between six months and two years. Independent organizations for faculty, facilities, curriculum, and learning outcomes have evaluated these programs.
