One book
The reference is Modern Refrigeration and Air Conditioning (22nd edition, 2025), with the pressure/temperature chart on page 1309 called out in the bulletin. TDLR's application page for registered technicians lists no exam; this one is for the certified credential, which also shortens the road to a contractor license.
Scheduling and exam day
- Eligibility first. TDLR reviews your application, then PSI emails you that you are eligible and how to book. You cannot book before that.
- Booking. Online through your PSI account, or by phone; your name must match your government ID exactly.
- On the day. PSI's TDLR bulletins ask you to arrive 30 minutes early with one valid government photo ID; late arrivals are turned away and lose the fee.
- Cancelling. Cancel or reschedule at least two days ahead through PSI, or the fee is forfeited.
- Results. Scores are given at the test center. PSI gives failing candidates a diagnostic report by topic, which is the best study guide for a retake.
