Exam Information

All persons seeking to become licensed as an Air Conditioning and Refrigeration Contractor or a Certified Technician must pass a licensing examination. The exam is administered by a third-party vendor, PSI, which has many locations throughout Texas.

The test you take will depend on the class of license that you are applying for as well as the endorsements that you have selected.

Exam Eligibility

After submitting your completed license application, required documentation and associated licensing fees, TDLR will approve your eligibility to take the exam.

Upon TDLR approval of eligibility, PSI will send you an email confirmation with instructions for scheduling an appointment to take the examination. (If an email address was not provided to TDLR at the time of application, you will receive a postcard via U.S. Mail from PSI with scheduling information).

Requirements for Identification

You must bring with you a VALID form of government-issued identification (for example, driver’s license, state ID, or passport), which bears your printed name, photograph, signature, date of birth, and expiration date. Identification provided must match all information provided by TDLR to PSI upon eligibility. If your ID does not contain the required information, you may be asked to provide other forms of valid identification to confirm your identity.

An expired driver’s license will be accepted only if accompanied by a VALID Texas Department of Public Safety temporary permit. Likewise, the temporary permits must be accompanied by the expired DPS driver’s license.

If your address has changed, you may update your address online.

If your name has changed, you will need to provide TDLR with a copy of your driver’s license or other form of government issued identification. Please email the information to CS.Air.Conditioning@tdlr.texas.gov.

Exam Results

A passing score is 70% or higher. Your grade will be handed to you at the test center by the PSI proctor after you have completed the test. PSI generates a score report which provides a diagnostic of the candidate’s strengths and weaknesses.

Re-Taking an Exam

If you fail an exam, you may schedule a retake with PSI, within 24-48 hours of your failed exam.

You may continue to retake the written exam until your application expires (one year from date submitted). When your application expires, you will need to submit a new application before you can retake the exam.
