What GA-CAC Training Actually Covers

Training for the Georgia Conditioned Air Contractor Class II (Unrestricted) License Exam is not a single course you buy and finish in a weekend. Because the credential is governed by the Georgia Construction Industry Licensing Board's Division of Conditioned Air Contractors and administered through PSI, "training" spans two distinct phases: the field experience and coursework required before the Board will even let you schedule the exam, and the focused exam-content review you do once you're approved to sit for it.

Both phases matter equally. Skipping ahead to memorizing code sections without the qualifying field hours won't get you approved to test in the first place. If you're still mapping out what the credential actually requires, start with our overview of GA-CAC Requirements 2026: Eligibility, Prerequisites & How to Qualify before diving into exam-specific prep.

Prerequisites Before You Can Sit for the Exam

Current Class II law requires five years of full-time qualifying experience broken into specific categories, and no amount of book study substitutes for these hours. Candidates need:

• Two years of commercial supervisory experience
• One year as a service technician or service supervisor
• Two years of installation as a lead mechanic, with at least one commercial year on systems exceeding 175,000 BTU of heating and 60,000 BTU of cooling

On top of the experience itself, applicants must submit experience affidavits and references, pass a criminal background check, and hold EPA Section 608 Type II and Type III certification. Training programs that ignore these documentation steps leave candidates stuck at the application stage, unable to even schedule with PSI.

There's also a technical-training layer that many people underestimate: completing Board-approved heat-loss/gain and duct-design training with Manuals J&D and N&Q documentation. This isn't optional supplemental reading - it's a required piece of the application package, and it directly overlaps with exam content in the System Design domain.

Exam Structure and What Training Must Prepare You For

The GA-CAC Class II exam is computer-based, multiple-choice, and reference-permitted, split into two parts of 3 hours and 30 minutes each. Across both parts you'll answer 100 scored questions plus 20 unscored beta questions, and you need a minimum final scaled score of 70 to pass. That's a long day of sustained, reference-based problem-solving - training has to build stamina, not just knowledge.

Because references are allowed, training shifts from pure memorization toward speed of navigation. You need to know exactly where a formula, table, or code section lives in your approved references before the clock starts, not during it. For exams scheduled May 1 through December 31, 2026, the approved references are the 2024 Georgia Gas and Mechanical Codes with Georgia amendments and the 2023 NEC. Only approved references may be used, and permanent tabs, highlighting, and underlining are allowed - but photocopies and handwritten notes are prohibited.

Training by Domain

The exam is organized into four content domains, and effective training allocates time in proportion to how heavily each domain is weighted. System Design carries the largest share at 55%, which should dominate your study calendar far more than the other three combined.

Because System Design is weighted so heavily, many candidates find it useful to walk through each domain in detail before building a study plan. Our GA-CAC Exam Domains 2026: Complete Guide to All 4 Content Areas article breaks down subtopics and question emphasis further.

Reference Materials and Open-Book Training

Since this is a reference-permitted exam, training must include hands-on repetition with the exact approved materials: the 2024 Georgia Gas and Mechanical Codes with Georgia amendments and the 2023 NEC. Spend training time simulating the exam environment - closed notes except for your tabbed, permanently marked reference books, timed to the same 3-hour, 30-minute blocks you'll face on test day.

Remember the rules: permanent tabs, highlighting, and underlining are allowed, while photocopies and handwritten notes are prohibited. Training with the wrong reference edition or with prohibited annotations wastes preparation time and risks confusion on exam day. Confirm your materials match the 2026 approved list before you build your tab system.

Building a Training Timeline Around the Two-Part Exam

A structured week-by-week approach works well for a two-part, domain-weighted exam like this one - as long as the schedule reflects GA-CAC's actual proportions rather than a generic template. Given that System Design is 55% of the content, it deserves multiple dedicated weeks, while the other three domains can share remaining time in proportion to their share of questions.

For a more detailed, day-by-day version of this approach along with common pitfalls, see GA-CAC Study Guide 2026: How to Pass on Your First Attempt. Running through timed practice questions on our practice test platform during weeks 1 through 6 helps you catch weak spots in each domain before the full simulation.

After Training: Application, Fees, and Retake Rules

Once your field experience, EPA certifications, Manuals J&D/N&Q documentation, and identity and lawful-presence documents are in order, you submit your application for Board approval. The Class II licensure-by-examination application fee is $110. Approval must happen before you can schedule your exam session through PSI - training and paperwork run on parallel tracks, and both need to finish before test day.

If you don't pass on the first attempt, training doesn't stop - it refocuses. After two failed attempts, a Board-approved review course is required before a third exam. That makes your first two attempts especially important to prepare for thoroughly, since a third attempt carries an additional training requirement built into the rules.

Once licensed, training becomes an ongoing obligation rather than a one-time event: licenses renew by November 30 of odd-numbered years, and you must complete four continuing education hours per year, totaling eight hours per renewal cycle.
