GA Conditioned Air reference list
Be sure to check with your testing center to verify that these are the correct references . This list came for PSI Exams website.
Passing the Georgia Conditioned Air Contractor exam isn’t about memorizing formulas — it’s about mastering the exact books the test is built from. This open-book exam allows approved reference materials in the testing room, but without a strategy, most candidates lose valuable time flipping pages instead of answering questions.
The official reference list includes the Georgia Mechanical and Gas Codes, ACCA design manuals, refrigeration texts, OSHA safety standards, and business law resources used to create the exam for both Class I (Restricted) and Class II (Unrestricted) licenses. Knowing which books matter most, how they’re organized, and how to find answers fast can be the difference between failing and walking out with a passing score. Our approach focuses on turning these required materials into tools you can navigate with confidence — so you’re not just studying harder, you’re testing smarter.
