Apply for a Technician Registration
Any person who assists a licensed air conditioning and refrigeration contractor in performing air conditioning and refrigeration maintenance or repair work must register as a technician.

Application and Fee
You must be at least 16 years old to apply.
Registrations are valid for 1 year from the date of issue.
Exemptions to Registration
Some persons and equipment are exempted from the technician registration requirements.
Please see the Exceptions to Technician Registration Requirements page for complete details.
Applicants with Criminal Convictions
If you have ever been convicted of a felony or misdemeanor (other than a minor traffic violation) or pleaded guilty or no contest (resulting in a deferred adjudication) to any in-state, out-of-state or federal criminal offense, you must provide a completed Criminal History Questionnaire (PDF) along with your application materials.
The department will conduct a criminal history background check on all persons who apply for a license. Criminal convictions are reviewed on a case-by-case basis. Licenses may be denied based on the nature of the conviction and how long prior to the application the conviction occurred. Depending on your criminal history, a review can take from one to six weeks to complete.
Individuals may request TDLR review their criminal background before actually applying for a license. TDLR uses the same process for this pre-application evaluation as the process described below. See the Criminal History Evaluation Letter page for more information.
Please see the Guidelines for License Applicants with Criminal Convictions, which describe the process that TDLR uses to determine whether a criminal conviction renders an applicant an unsuitable candidate for the license, or whether a conviction warrants revocation or suspension of a license previously granted.
