Tennessee HVAC Training Schools & Certification

In Tennessee (TN) with its sticky hot summers and cool winters, there is a thriving demand for skilled heating, ventilation, air conditioning, and refrigeration (HVAC-R) professionals, especially in cities with high rates of construction such as Nashville. Not only is climate control a high-growth, lucrative industry—two facts discussed in the subsequent section of this guide—but these workers also have a wealth of resources at their fingertips through the strong network of contracting and trade associations in the state.

As proof of point, the Tennessee Association of Plumbing-Heating-Cooling Contractors (TAPHCC) is a not-for-profit association with regional chapters in three areas: Knoxville, Middle Tennessee, and Northeast Tennessee. The organization has several goals, including the promotion of the most efficient and groundbreaking technologies in the industry; progress in sanitation and standardization of methods; compliance with all legislation; and to provide training and other resources. Additionally, the Nashville Area Plumbing and Mechanical Association provides legal advocacy, charity events, and discounts on various services such as insurance.

HVAC workers in Tennessee (TN) must have state licensure through the Tennessee Board for Licensing Contractors to complete projects in excess of $25,000, and all installers require an electrical contracting license to do their work; local credentialing also varies by city, although the job responsibilities are similar for HVAC professionals in TN and beyond.

These workers visit service sites to fulfill contractual or warranty-related obligations; read blueprints and mechanical diagrams; calculate heat loads & losses of systems; recover and safely handle refrigerants; repair, install, and maintain HVAC systems and components (e.g., motors, wiring, intake & exhaust fans, refrigeration circuit, water pumps, relays, thermostats, hermetic compressors, humidifiers); keep on top of developments in the industry; maintain detailed service records; work in compliance with all legislation; travel to job sites; and make efficiency recommendations to customers.

It’s important to note that all HVAC-R workers in TN and across the country who handle refrigerants must achieve a national credential: the EPA Section 608 certification, which is discussed in the licensing section below.

This guide covers accredited HVAC schools in Tennessee and the state’s occupational growth, salary prospects, and licensing procedures.

Occupational Demand for HVAC Professionals in Tennessee

As mentioned in the introduction, HVAC is a high-growth industry. In fact, the Bureau of Labor Statistics (BLS May 2023) anticipates a 9 percent explosion in HVAC positions nationwide between 2023 and 2033, much more robust than the 4 percent average growth projected for all occupations during that period.

Interestingly, Projections Central (Jan. 2025)—a data organization partnered with the US Department of Labor—found that for HVAC work in TN specifically is comparable to the national statistics. It reported that there would be a 9.8 percent increase in HVAC positions across Tennessee between 2022 and 2032 (an additional 1,010 openings).

So what are the factors contributing to the healthy, thriving demand for qualified HVAC professionals in Tennessee? First, these systems generally need to be replaced every 10 to 15 years, not to mention required retrofitting of old systems to make them compatible with new structures or technologies. Secondly, the rise of regular service and maintenance contracts that accompanies the installation of modern systems may ensure regular work throughout the year, even during the typically low seasons (spring and fall). Maintenance and repair work is especially stable while specializing in HVAC installation may thrive more in cities with high rates of construction.

The BLS (May 2023) reported that 8 percent of HVAC mechanics and installers were self-employed in 2023, and 67 percent worked for plumbing, heating, and A/C contracting companies. Some of these skilled professionals in TN work normal business hours, while others may be called upon to service equipment on evenings, weekends, or holidays, particularly during the high summer season.

Also, HVAC workers incur a relatively high risk of injury and illness compared to other US occupations. They lift heavy equipment, deal with electrical wiring, and handle refrigerants—three activities which increase one’s risk of muscle strains, electrical shock, burns, and frostbite, among other maladies. That said, these problems can generally be kept to a minimum with proper training and use of safety equipment.

Despite the physical challenges within the profession, there is further evidence that the employment climate is thriving for HVAC workers in TN. In fact, common job posting sites are filled with opportunities. For example, Indeed (Jan. 2025) had links to 100+ relevant HVAC worker openings in TN, including positions at Pipe Wrench, Iceberg Heating Cooling and Plumbing, Rivertech Heating and Air Conditioning, and Ada Air Conditioning. Additionally, Monster (Jan. 2025) advertised HVAC jobs in TN at places such as United Rentals, Lee Company, and Marriott International, Inc.

Tennessee HVAC Salaries – How Much Do TN HVAC Workers Make?

According to the Bureau of Labor Statistics (BLS May 2023), HVAC mechanics and installers enjoy good wages around the country, particularly in an occupation that generally requires just six months to two years of postsecondary education.

Among the 397,450 HVAC workers around the US, the BLS (May 2023) found an average annual salary (annual mean wage) of $59,620. In Tennessee, the 9,880 HVAC professionals working there earned an average of $50,410. In more detailed terms, here were the salary percentiles in this occupation in the US and Tennessee specifically:

	United States	Tennessee
Number of HVAC professionals employed	397,450	9,880
Annual mean wage	$59,620	$50,410
10th percentile	$37,270	$36,920
25th percentile	$46,550	$39,470
50th percentile (median)	$57,300	$48,050
75th percentile	$71,120	$60,610
90th percentile	$84,250	$66,520

Salary figures do vary slightly by the source of data. PayScale—an aggregator of self-reported salaries—found the following percentiles among its HVAC respondents nationwide in October 2024:

10th percentile: $40,000
50th percentile (median): $61,249
90th percentile: $94,000

As noted above, the average salary for HVAC workers in Tennessee is somewhat lower than that of the rest of the nation. As with any salary projections, taking into account the cost of living is also important. As such, the Missouri Economic Research and Information Center (MERIC 2024) found that TN was the 10th most affordable state. For HVAC technicians this means even lower than average salaries will go a bit further than they would in some costlier nearby states.

The BLS designated 14 regions within Tennessee for which employment data is available. The 3,480 HVAC workers in the Nashville-Davidson-Murfreesboro-Franklin, TN area earned the highest average salary in the state at $53,610, while West Tennessee nonmetropolitan area workers had the lowest average salary at $43,380.

HVAC Licensing & Certification in Tennessee

Prior to seeking work, all HVAC workers in Tennessee must ensure that they have proper credentialing. As mentioned above, there’s one nationally mandatory certification for all people who work with refrigerants: the EPA Section 608 certification. There are four categories:

Type 1 (small appliance)
Type 2 (high-pressure appliances)
Type 3 (low-pressure appliances)
Type 4 (universal)

Please note that preparation for this credentialing exam is usually included in accredited HVAC training programs.

Other national entities of note and sample certifications offered include:

HVAC Excellence (e.g., Heating, Electrical, Air Conditioning Technology [HEAT], HEAT Plus, heat oil combustion, systems diagnostics, green awareness, etc.)
North American Technician Excellence or NATE (e.g., air conditioning, air distribution, heat pump, hydronic oil, commercial refrigeration, etc.)
Refrigeration Service Engineers Society or RSES (e.g., commercial air conditioning, domestic service, dynamic compression, etc.)

To discover in detail how to achieve any of these credentials, check out the HVAC certifications page.

As mentioned in the introduction, all HVAC workers performing $25,000 or more in work on systems must have a mechanical contractor’s license (CMC-C) issued by the Tennessee Board for Licensing Contractors. To qualify, candidates must:

Complete a CMC-C application
Pass two exams (TN Business & Law Management Exam and a Trade Exam)
Offer proof of insurance
Submit a financial statement
Pay an application fee

These licenses may require a candidate interview as well and are valid for two years.

The TN Department of Commerce & Insurance adds that all HVAC workers in TN performing repair or maintenance services under $25,000 don’t need state licensure, although it is important to note that the installation of all HVAC systems requires a TN-issued electrician’s license (LLE). Many cities and regions have their own specific requirements for HVAC credentialing. A list of each regional authority is available on the TN State website.

Above all, it is crucial to ensure that one has all necessary credentials before beginning work, so HVAC workers in TN are strongly encouraged to check with municipal governments for all licensing details.
