Why do you need a license for HVAC work?

To work on cooling systems as an HVAC technician in the state of Texas you'll need an Air Conditioning and Refrigeration Contractor License from the Texas Department of Licensing and Regulation (TDLR). Depending on the level of licensure, you'll be able to perform different levels of HVAC service.

Jobs for HVAC technicians

There are some real advantages in pursuing a career as an HVAC installer. Pay is competitive, the training time is relatively short, and according to the US Bureau of Labor Statistics, the growth in the number of jobs is projected to be good.

Salary prospects for the HVAC field

The median pay for HVAC contractors is competitive with many skilled trades. Nation-wide the average annual compensation for an HVAC installer is about $50,000 per year. Pay in Texas is comparable with the national average.

Texas HVAC technician licenses

In Texas, licenses for those working on HVAC systems are classified under Air Conditioning and Refrigeration Contractors. To start your career path, you'll need to get a Technician License. There are two levels of technician license class: Registered Technician and Certified Technician.

Registered Technician

The first step in license classes is the Registered Technician. As a registered technician, you'll shadow a licensed air conditioning and refrigeration contractor to gain experience. There is no exam for this license, just complete an application and submit the necessary fee

Certified Technician

After you've gained 24 months of experience working under the supervision of a licensed air conditioning and refrigeration contractor, you may apply to become a Certified Technician. There is no exam for this level. An application, proof of experience, and a fee are the only qualifications that are required.

Applying for a Contractor License

Once you've met either of the following requirements, you may apply for a contractor license:

  • You've completed at least 48 months of supervised work under a licensed air-conditioning and refrigeration contractor in the last 72 months.
  • You have had a Certified Technician qualification for the previous year and have completed 36 months of work in air conditioning and refrigeration under the supervision of a licensed contractor in the past 48 months.

There are exceptions to these requirements. You can examine these at the TDLR website.

Class A and Class B Licenses

HVAC contractors have the choice of applying for a Class A or Class B license. Here are the differences between the two license classes:

Class A

The Class A license allows you to work on HVAC systems of any size.

Class B

With a Class B license, you may work on heating systems of up to 1.5 million BTUs per hour and less. You may work on air conditioning units of 25 tons and less.

HVAC Endorsements

Endorsements qualify the contractor to perform work in a variety of specialized subcategories, including:

Environmental Air Conditioning endorsement

These endorsements cover a variety of air treatments, including humidity, temperature, cleanliness, circulation, and ventilation.

Commercial Refrigeration endorsement

This endorsement is for the use of absorption and mechanical equipment for humidity and temperature control in refrigerated spaces.

Process Cooling or Heating endorsement

Oriented towards production spaces and equipment enclosures, including temperature, humidity, and cleanliness of the air in a designated space.

The licensing exam

There are minor differences between the actual exams for the Class A and Class B licenses. The Class B exam consists of 100 questions with a 3-hour time limit, while the Class A license consists of 120 questions and has a 4-hour time limit. Experience requirements and exceptions are the same for both exams.


Examination eligibility requirements are set by the TBLR. You can find current information here.

Re-taking a failed exam

You have a one-year window to retake your examination. You may retake as many times as you wish until your current application expires.

Pass/Fail Rates

A score of 70% is required to pass the examination. Be sure to study - the pass rate is usually between 30 to 50%, depending on the examination!

Commercial general liability insurance

Once you've passed the examination, you'll need to submit a Certificate of Insurance to the TDLR before becoming an HVAC installer contractor. The insurance requirements vary depending upon your license class. The form listing insurance requirements can be found here.
