How Long Does it Take to Get an HVAC Contractors License in Tennessee?
The HVAC industry is growing and advancing by leaps and bounds. If you want to join this essential field, there are a couple of ways to get started. It’s not quick, but the need for these highly trained tradespeople offers job security and the opportunity to own your own business.
HVAC/R professionals in Tennessee can make a good living and are almost guaranteed a long career because skilled craftsmen are in high demand and short supply. There are over 394,100 Heating, Air Conditioning, and Refrigeration Mechanics and Installers in the United States, according to the U.S. Bureau of Labor Statistics, and 8,740 work in Tennessee. That number nationwide is expected to grow 5 percent from 2021 to 2031 — adding more than 20,000 of these skilled workers to the ranks. The U.S. Department of Labor’s job search website, CareerOneStop, projects the growth rate in Tennessee to be more than twice that at 12% for HVAC mechanics and installers.
The Associated General Contractors of America, says contractors are hiring. In the 2020 AGC-Autodesk Workforce Survey, 60% of firms in the U.S. and 80% of firms in Tennessee had unfilled hourly craft positions.

Climate control and refrigeration systems in our homes and businesses wear out and break down and now with more of an emphasis being placed on energy efficiency and reducing pollution, systems need to be retrofitted, upgraded or replaced entirely to remain compliant.
Because it is such an exacting job, the licensing requirements for HVAC workers and contractors can be rigorous. They vary from state to state and in some cases, like in Tennessee, from locality to locality.
Licensing Requirements for HVAC Contractors in Tennessee
Is a license required to perform HVAC work in Tennessee? Yes.
To be an HVAC professional in Tennessee, you must be licensed. Licenses are issued at both the state and local level. Cities and counties throughout the state issue traditional journeyman or master contractor licenses while the state only issues HVAC Contractor licenses.
These HVAC contractor licenses are issued on a statewide level by the Tennessee Department of Commerce and Insurance through the Tennessee Board for Licensing Contractors.
A Tennessee contractor's license is required BEFORE bidding or offering a price, for projects $25,000 and up (includes materials and labor), as a prime (general) contractor; and also subcontractors performing electrical, mechanical, plumbing, HVAC, roofing, and masonry are also required to be licensed as a contractor, when the total portion on the project is $25,000 or more; masonry, when $100,000 or more.
A state-level license is not required for the technicians and installers they employ. Local jurisdictions have their own licensure for the mechanics and installers. Municipalities can also have their own contractor license, but those who have a Certified Mechanical Contractor (CMC) license through the state are not required to test with the local government.
Types of HVAC Licenses in Tennessee
What are the different types of HVAC licenses in Tennessee? There are two statewide license classifications for HVAC Contractors in Tennessee.
CMC — Full Mechanical Contractor: This license requires education and training in Plumbing as well as HVAC, and you must be pre-approved by the Board before you can take the examination.
CMC-C — Mechanical – HVAC/Refrigeration Contractor does not require pre-approval for testing. However, some municipalities will require that you also be an LLE (Limited Licensed Electrician) from the state level for the wiring aspects of the HVAC work if you have a CMC-C rather than a Full Mechanical Contractor license, even if the project is less than $25,000. Also, solar thermal or geothermal installers related to heating, ventilating, and air conditioning (HVAC) are required to have the CMC-C license.
Steps to Get an HVAC Contractor License in Tennessee
You must be at least 18 years of age.
Have a high school diploma or GED.
Gain work experience and get classroom instruction either through an apprenticeship or technical college program.
Once you’ve gained enough knowledge/experience through apprenticeship or employment after college/vocational school, you’ll need to take the locally mandated exam and apply for your journeyman license in the jurisdiction where you intend to work.
If you want to bid on projects of greater than $25,000, you’ll need to take the statewide trade exam and Business and Law exam and apply for your Contractor License. Remember, for a CMC-C License, you do not need to be pre-approved to test, but for the full CMC, you must be pre-approved to take the trade exam.
After receiving a passing grade on the exam, you will need to complete the Contractor’s License Application Package including a financial statement either reviewed or audited by a certified public accountant and proof of general liability insurance and workers' compensation insurance.

How to Get an HVAC License in Tennessee
The first step in getting the state of Tennessee Contractor License is to take and pass the state-mandated contractors exam. You do not need pre-approval to register for the CMC-C exam, but you must be pre-approved by the Tennessee Board for Licensing Contractors to sit for a Full Mechanical Contractor exam.

You can save time by applying online and may pay by credit or debit card or e-check.
However, your journey to a statewide license will begin well before this at the local level.
WORK EXPERIENCE: Before you can apply for a local or state license, you must gain the necessary years of experience and classroom instruction. The requirements vary in cities and counties throughout the state. For specific details, contact your local licensing board.
In many cases, you need a minimum of 8,000 hours (or four years) of work experience to be eligible to apply for your local level journeyman HVAC license and anywhere from 576 to 900 hours of classroom-based instruction. This can be done through completing a degree at a technical college and then working for a licensed contractor or HVAC business or through a registered apprenticeship.
APPLY TO TAKE EXAMINATION: Once you’ve fulfilled the work experience requirements, you may apply to take the local licensing exam. After successfully passing the exam and providing any other documentation the local jurisdiction prescribes, you will be issued a journeyman or master license as appropriate.
Chattanooga, Tennessee, for example, has a Board of Mechanical Examiners to oversee the examination and licensing of master and journeyman mechanical contractors. You also must register first as a helper so the board can document your hours to be applied toward the three years of experience required for the journeyman license. Then you’ll need to work for another three years with that license and pass an exam before qualifying for master mechanical contractor.
Memphis/Shelby County, Tennessee, issues both First-class Mechanical Contractor or Third-class Mechanical Contractor licenses through the Shelby County Mechanical-Gas Code Board.
Shelby County requires both First-class or Third-class Mechanical Contractors to be at least 21 years old and have four years of experience for First-class or two years of experience for Third-class. The exam fee for either is $150 and the Board specifies that projects must be valued at less than $25,000 coinciding with state law.
STATE CONTRACTOR LICENSE: If you choose to work on projects valuing $25,000 or more, you will need your Tennessee Contractor’s License. Also, in certain municipalities even on jobs valued at less than $25,000, HVAC contractors may be required to be licensed at the state level. That license would be for Limited Licensed Electrician (LLE).
To obtain an HVAC contractor license, you must pass a business and law exam and a trade exam, submit the appropriate application and supporting documentation, which includes financial statements either reviewed or audited by a Certified Public Accountant, and proof of workers’ compensation and general liability insurance.
All state contractors' licenses are issued with a classification, like CMC for Full Mechanical Contractor and a monetary limit. The monetary limit is an amount approved for contracting/bidding, and this is based upon your financial statement prepared by a CPA, and experience. A “reviewed” financial statement is required to obtain a monetary limit of $3,000,000 or less; an “audit” is required to obtain a monetary limit more than $3,000,001 to Unlimited. Financial statements must be prepared by a properly licensed CPA. A contractor’s license is issued in the exact name as on the Financial Statement.
The fee to obtain an HVAC contractor license is $250, and licenses must be renewed every two years. The renewal fee is $200. Applicants who wish to establish a corporation, LLC or Partnership must register with the Tennessee Secretary of State’s Office.

Who Issues HVAC Licenses in Tennessee?
HVAC licenses are issued by cities and counties throughout Tennessee. Statewide Contractor Licenses are issued by the Tennessee Department of Commerce and Insurance through the Tennessee Board for Licensing Contractors for projects that are $25,000 or more. Also, in certain municipalities even on jobs valued at less than $25,000, HVAC contractors may be required to hold an LLE at the state level.
Does My Tennessee HVAC License Work in Any Other State?
Tennessee does have reciprocal agreements with several other states to waive the trade exam but still requires that out-of-state contractors take the Business and Law Management exam before practicing in Tennessee. The process to obtain a Tennessee license without retaking the trade exam can be found here.
The states with this limited reciprocity are Alabama, Arkansas, Georgia, Louisiana, Mississippi, North Carolina, Ohio, South Carolina, and West Virginia.
HVAC Specific Requirements: EPA Certification
Everywhere throughout the country, including Tennessee, federal-level EPA regulations under Section 608 of the Clean Air Act require that technicians who maintain, service, repair, or dispose of equipment that could release refrigerants into the atmosphere must be certified. EPA Section 608 HVAC Certification is required for any professional who conducts refrigerant line-pressure tests or handles or adds refrigerant to existing air conditioning systems.
Most training programs can direct you to how and where to get that certification and many even make it part of the curriculum, or your employer will require you to get it before handling refrigerant. You can also go to EPA.gov and key in 608 Certification in the search bar to find out which institutions in your state offer certification programs.
Certification Exam: You must acquire your EPA Certification from an approved organization. A list of these organizations can be found on the EPA’s website.
There are four types of EPA Certifications for Refrigerant. They allow for different levels of certification for different scopes of work.
Type I – for servicing small appliances containing five pounds of refrigerant or less.
Type II – for servicing high-pressure units that contain five pounds or more of refrigerant (including most small commercial and residential systems).
Type III – for servicing or disposing of low-pressure appliances.
Universal – for servicing all systems and appliances covered under Types I, II, and III. Generally more useful than targeting any one specific certification.
Core Exam: For all certifications, you must pass the “Core Section” of the EPA certification exam. It covers the following topics:
Clean Air Act and the Montreal Protocol
Section 608 regulations
Substitute refrigerants and oils
The Three R’s (Recover, Recycle, Reclaim)
National HVAC Certifications
Other certifications can help you demonstrate your proficiency to potential employers and clients. North American Technical Excellence (NATE) certification, ASHRAE (American Society of Heating, Refrigeration and Air-Conditioning Engineers) certification, and other professional certifications are not required but can add to your marketability as a service provider and therefore increase your opportunity to make more money.
Other Requirements Unique to Tennessee
