Open Book Test

The ICC Louisiana (New Orleans) First Class Stationary Air Conditioning 636-LA examination is an open book test. Candidates have three hours to complete 60 multiple-choice questions and must follow current ICC examination rules regarding permitted references and materials.

The open-book format makes efficient reference navigation an important study skill. Candidates should be able to recognize the subject being tested and move quickly to the appropriate mechanical-code provision or refrigeration topic instead of searching broadly through reference materials for every question.

The 2015 International Mechanical Code supports preparation involving general mechanical requirements, duct systems, equipment installation, ventilation, refrigeration systems, clearances, mechanical-system safety, and other regulated installations.

Modern Refrigeration and Air Conditioning, 22nd Edition provides broad technical coverage of refrigeration and HVAC principles. It can support review of refrigeration theory, compressors, evaporators, condensers, system components, controls, airflow, troubleshooting, maintenance, and practical air-conditioning concepts.

The official 636-LA examination bulletin identifies multiple approved references for the examination. Candidates should follow the current ICC examination bulletin when determining which specific books and editions may be brought into the testing room.

During preparation, practice identifying the category first. A question about compressor operation should send you toward compressor and refrigeration-system material. A question involving duct construction or mechanical installation should suggest the International Mechanical Code. A question involving electrical sequence or system controls should direct attention toward electrical and control concepts.

Using practice questions as reference drills can make open-book preparation more productive. After answering, locate the supporting technical information and review related concepts rather than simply memorizing the correct choice.
