- How much does it cost to renew my license?
- What is required to renew my TDLR air conditioning and refrigeration contractor license besides submitting my renewal application and renewal fee?
- Should I wait to submit my license renewal application until after I have completed my eight hours of continuing education?
- My license has been expired for more than 18 months. How do I get it back?
You can renew online 24 hours a day, 7 days a week using our Online Licensing Services.

Each ACR Contractor is required to complete eight hours of continuing education to renew their license, including two hours of instruction in Texas air conditioning and refrigeration law and rules that regulate conduct.
Continuing education hours must be completed within the period of the license. (Example: if the license is effective from June 1, 2011 to June 1, 2012, the hours must be completed during that period only. A course taken in April 2011 is not within the license period, and will not count for the required continuing education hours.)
No. You may file your renewal application at any time during your renewal period. We encourage you to file the application early so your license won’t expire and you won’t have to pay late renewal fees.
If your license has been expired for more than 18 months but less than three years, you may renew online or submit a “Request to Executive Director for Expired License Renewal” form with the required renewal fee.
If your license has been expired for more than three years you may not renew your license. You must apply for a new license.
You may be subject to enforcement actions, including administrative penalties and sanctions, for operating with an expired license (expired less than 18 months) or operating without a registration (expired 18 months or more).

Providers are required to submit to TDLR your continuing education course completion information. If you have taken a course from one or more providers, each provider must transmit that information to TDLR and also issue you a certificate of course completion.
CE course completion information is available on the web site for your review. If you have a question about the information posted on the web site, please check first with the provider. If you continue to have questions, please contact TDLR: by phone, (512) 463-6599 or toll-free in Texas (800) 803-9202; or by email firstname.lastname@example.org.
Your provider will issue you a course completion certificate. If you have questions, please contact your provider

Yes. TDLR requires the provider to monitor licensee attendance for all courses, including online courses. If a licensee does not meet the provider’s monitoring requirements, no continuing education hours will be given.
Yes. You can use the CE Courses Lookup on TDLR’s web site.
If your course completion is not posted seven days after you completed the course, contact your provider.
If you do not receive your course completion certificate within 15 days from the end of your course, please check with your provider.
Instructors who are licensees may arrange with the provider to get continuing education hours for that portion of the course which the instructor taught. However, if the instructor does not teach the entire course, the instructor must attend the remainder of the course to obtain credit for the whole course. No partial course credit is allowed.
If the college course is a TDLR approved continuing education course, then the course hours can be used for license renewal. However, the courses must be taken during the period of the license being renewed. Courses which are not approved by TDLR as continuing education courses cannot be used for license renewal.
You are required to keep a copy of the continuing education certificate for one year after the date you completed the course.
