Why "Exam Dates" Works Differently for the ACR Exam
If you searched for "ACR exam dates 2026" expecting a calendar of quarterly testing windows, here's the good news: the Texas Air Conditioning and Refrigeration (ACR) Contractor License Exam - the selected Environmental Air Class A examination administered by PSI on behalf of the Texas Department of Licensing and Regulation (TDLR) - doesn't work that way. There's no once-a-quarter application deadline you have to hit or miss. Instead, once TDLR approves your eligibility, you schedule your own computer-based, in-person exam appointment at a PSI test center on a date that works for you.
That doesn't mean timing doesn't matter, though. Reference material updates, license renewal cycles, and your own experience-hour timeline all create real deadlines you need to track. This guide walks through the actual dates that matter in 2026, how the scheduling mechanics work, and how to plan a study calendar around whatever exam date you pick.
What Changed for 2026: Bulletin and Reference Updates
Two dates matter more than any others if you're planning to test in 2026:
- July 9, 2026 - the PSI candidate bulletin for the Environmental Air Class A exam was updated. Always confirm you're studying from the current bulletin version rather than an older PDF that's been floating around a study group or forum.
- September 1, 2026 - the 2024 editions of the International Mechanical Code (IMC), International Fuel Gas Code (IFGC), and Uniform Mechanical Code (UMC) take effect as approved references. If your test date falls before September 1, 2026, you'll be tested against the prior code editions; if it falls on or after, you need the 2024 editions in hand.
This matters directly for exam-day logistics because the ACR exam is open-book. You're allowed to bring approved references that already contain your own notes, highlighting, underlining, and permanent tabs - but only if those references are the correct, currently approved editions. Tabbing an outdated code book won't help you if the version itself is no longer accepted on your specific test date.
Key Takeaway
Before you schedule, check which code editions your intended test date requires, and build your tabbed reference set from that edition - not from whatever copy you already own.
How to Schedule Your Test: Fees, Applications, and Timing
Scheduling the ACR exam is a two-payment, two-agency process, and understanding the sequence helps you avoid dead time between steps:
- TDLR application and fee. You submit your application to TDLR along with a $115 application fee. This is where your experience documentation and eligibility pathway are reviewed.
- TDLR approval. Once TDLR confirms you meet the experience and age requirements, you become eligible to schedule with PSI. This is the gatekeeping step - you cannot book a PSI seat before this happens.
- PSI exam fee and scheduling. You then pay the separate $74 PSI examination fee and select an available date and test center location.
For a full line-item breakdown of what you'll spend from application through license issuance, see the ACR Certification Cost 2026: Complete Pricing Breakdown. And if you're still confirming whether you even qualify to start this process, the ACR Requirements 2026: Eligibility, Prerequisites & How to Qualify guide breaks down every pathway in detail.
Eligibility Timelines Before You Can Even Book a Seat
The real "deadline" pressure in this process usually happens before you ever touch a PSI scheduling calendar - it's in accumulating qualifying experience. Applicants must be at least 18 years old and generally need one of the following:
- 48 months of supervised practical experience within the preceding 72 months, or
- 12 months as a certified technician plus 36 months of qualifying experience within the preceding 48 months
Approved substitutions can adjust these timelines in specific cases. If you're mapping out when you'll realistically be eligible to schedule an exam, work backward from these windows rather than forward from today - knowing your 72-month or 48-month lookback period helps you understand exactly how much documented experience you need banked before submitting your TDLR application.
Exam Day Logistics: Format, Language, and What to Bring
Once your date is booked, here's what actually happens in the test center:
- Format: in-person, computer-based, multiple-choice
- Length: 120 scored items plus 5 non-scored items (135 total questions on screen)
- Time allowed: 4 hours
- Passing score: 70%
- Languages: available in English and Spanish
- References: open-book, with approved materials allowed to include preexisting notes, highlighting, underlining, and permanent tabs
- Calculator: a compliant nonprogrammable calculator is permitted
The non-scored items are mixed in with the scored ones and aren't identified during the test, so there's no way to skip or rush through questions you suspect are pretest items - treat every question on screen as if it counts. For a full breakdown of exactly what a 70% threshold means in raw question terms, read ACR Passing Score 2026: Exactly What You Need to Pass.
Key Takeaway
Since references are open-book, your exam-day speed depends more on how well-organized your tabs are than on memorization - build your reference system weeks before your scheduled date, not the night before.
Domain Weighting and Why It Should Drive Your Booking Date
The Environmental Air Class A exam is built from 14 content domains, each carrying a specific percentage of the 120 scored items. Air Distribution is the largest single domain at 15%, followed by Equipment Requirements and Design at 11.67% and HVAC Systems at 9.17%.
| Domain | Weight |
|---|---|
| Air Distribution | 15% |
| Equipment Requirements and Design | 11.67% |
| HVAC Systems | 9.17% |
| Service | 10% |
| Testing | 10% |
| Basic Refrigeration Components | 5% |
| Combustion Air | 5% |
| Controls | 5% |
| Piping | 5% |
| Refrigeration Principles | 5% |
| Safety | 5% |
| Texas Laws and Rules | 5% |
| Ventilation | 5% |
| Venting | 4.17% |
These percentages are calculated from PSI's official 120-scored-item outline. If you're deciding how far out to schedule your exam, this table is your real planning tool: the higher-weighted domains deserve the earliest and most repeated review sessions. For deep coverage of each of the 14 areas, see the ACR Exam Domains 2026: Complete Guide to All 14 Content Areas.
Air Distribution
As the largest domain at 15%, candidates should be comfortable with duct sizing, layout, airflow balancing, and distribution equipment selection well before locking in a test date.
- Duct system design and airflow calculations
- Distribution equipment selection for varying load types
Equipment Requirements and Design
At 11.67%, this domain covers how equipment must be selected and installed to meet code and manufacturer specifications - a natural pairing with your reference-book tabbing strategy.
- Matching equipment specifications to application requirements
- Cross-referencing manufacturer data with code requirements
Building a Study Calendar Around Your Test Date
Once you've picked a target PSI appointment, work backward. A simple four-week structure that respects the domain weighting above looks like this:
Heavyweight Domains
- Air Distribution (15%)
- Equipment Requirements and Design (11.67%)
Mid-Weight Domains
- HVAC Systems (9.17%)
- Service (10%)
- Testing (10%)
Standard-Weight Domains
- Basic Refrigeration Components, Combustion Air, Controls, Piping, Refrigeration Principles, Safety, Texas Laws and Rules, Ventilation (5% each)
- Venting (4.17%)
Full Practice and Reference Organization
- Timed practice sessions under the 4-hour, 120-item format
- Finalize tabbed references against the correct code editions for your test date
This is a scaffold, not a rigid formula - some candidates need more time on Testing or Service depending on their field experience. If you want a more detailed methodology for how to structure daily review sessions inside this kind of calendar, see the ACR Study Guide 2026: How to Pass on Your First Attempt. Running practice questions against realistic domain weighting at ACR Exam Prep during weeks 3 and 4 is one of the most direct ways to confirm you're ready before you lock in your final scheduling window.
After You Pass: License Issuance, Insurance, and Renewal Dates
Passing the exam isn't the finish line - a few post-exam dates matter for staying licensed:
- Insurance requirement: Class A contractors must maintain commercial general liability coverage of $300,000 per occurrence, $600,000 aggregate, and $300,000 for products and completed operations. Have this coverage lined up before you expect your license to be issued.
- Renewal cycle: the license is issued for one year and renews for $65.
- Continuing education: renewal requires 8 hours of continuing education, including 1 hour specifically on Texas law and rules.
Mark your renewal date the same way you marked your exam date - as a real deadline, not a someday task. Letting continuing education slide to the last week of your renewal period is a common, avoidable source of stress.
Common Scheduling Mistakes That Push Back a Test Date
A few patterns repeatedly delay candidates from getting into the PSI test center:
- Submitting incomplete experience documentation to TDLR, which stalls approval before scheduling is even possible.
- Booking a date before confirming reference editions, then discovering the required code books changed under the September 1, 2026 update.
- Underestimating the 4-hour, 135-question pace and not practicing under timed conditions beforehand.
- Assuming the exam is harder or easier than it is based on secondhand accounts - the How Hard Is the ACR Exam? Complete Difficulty Guide 2026 breakdown and the ACR Pass Rate 2026: What the Data Shows analysis both give a clearer, data-based picture than forum anecdotes.
Frequently Asked Questions
No. The Environmental Air Class A exam is scheduled individually through PSI once TDLR approves your application, so you pick an available date and location rather than waiting for a quarterly window.
That's when the 2024 IMC, IFGC, and UMC editions become the approved references. Confirm which edition applies to your specific test date before finalizing your reference book tabbing.
You'll pay a $115 TDLR application fee first, then a separate $74 PSI examination fee once TDLR approves your eligibility to test.
Yes. The exam is open-book, and approved references may already contain notes, highlighting, underlining, and permanent tabs, along with a compliant nonprogrammable calculator.
The license is valid for one year. Renewal costs $65 and requires 8 hours of continuing education, including 1 hour on Texas law and rules.
Scheduling flexibility is one of the more candidate-friendly parts of this process - use it deliberately. Confirm your eligibility window, check the current reference editions, and pick a date only once your domain-by-domain preparation, guided by resources like the ACR Cheat Sheet 2026: One-Page Review of Must-Know Facts, actually matches the exam's 4-hour, 120-scored-item format.
