How to pass the Texas HVAC certification exam

Written October 2, 2026

You finished your program hours. The TX ACR Certified Technician Examination is the last gate between you and the license. This page explains what it asks, how it is scored, and how to study for it without wasting weeks.

Know the numbers before you study

The exam is the TX ACR Certified Technician Examination, administered by PSI. You sit it after finishing a TDLR-approved training program in Texas. It is a 60-question test, and you need 42 correct to pass. You get 112 minutes.

Two numbers decide your strategy. Missing 18 of 60 questions still leaves you a pass, so you do not need to know everything. You need to be fast and right on the topics that carry the most questions. And 112 minutes for 60 questions is just under 2 minutes each. A question you cannot look up in a minute is one to mark and leave for the end.

It is open book, so speed in the book is the skill

The exam is open against a list of reference books. That changes what studying means. A closed-book test rewards memory. An open-book test rewards one thing: how quickly you can turn a question into the right page. Students fail this exam with the book open in front of them, because they never practiced finding things in it.

  1. 01 — Tab the references

    Put a tab on the sections your program tested most. On exam day, a tab is seconds.

  2. 02 — Practice lookups, not reading

    Take a question, find the answer in the book, write down the page. Repeat until lookups take under a minute.

  3. 03 — Read the answer where it lives

    Do not stop at the letter. Read the passage, so the next question on the same topic needs no lookup at all.

A score is not a plan

Most free practice tests and app-store question banks tell you one thing: your score. A score of 68 percent says the practice run failed. It does not tell you which of the exam topics cost you the points, so the next study session guesses. The fix is to study by topic, not by test. Find the 2 or 3 topics where you miss the most questions, drill only those until the misses stop, then re-test.

This is the problem jayden is built for. A short Diagnostic maps you against every topic on the exam and shows the result as a Weak Spot Map. From there a Study Plan tells you what to drill next. Every Question comes with an Explanation that ends in a Reference: the book and section the answer comes from. You practice the open-book lookup while you practice the topic.

The Diagnostic is free, and the full prep is a one-time $49 with access until you pass. See the sample map or read what the Pass includes.

Studying around shifts

Most students study on a phone, between class and work, tired. Short sessions fit that life better than long ones. A Drill on one topic takes minutes and ends with a clear next step, which is the part that matters when you open the app again tomorrow. A fail on the real exam costs another PSI fee and weeks of waiting, so the goal is not to study more hours. It is to make each hour land on the topics that will actually appear.
