The AIRLIMITS CTC Certified Tester Directory is an independent service operated by AIRLIMITS. It is not affiliated with, endorsed by, or sponsored by the California Air Resources Board (CARB).

Certified Tester information is sourced from CARB’s public for-hire Certified Tester list when available. Inclusion on the public list is optional, so this directory may not contain every Certified Tester. Listings may be incomplete or out of date between refreshes. Always confirm credentials, services offered, pricing, and availability directly with the Certified Tester before scheduling.
