Practice benchmark only: PSI publishes the Ohio commercial HVAC trade exam as open book, 100 questions, 240 minutes, with a 70% passing score, and a separate Business & Law exam of 50 questions in 2 hours at 70%. This practice exam flags 70% as a PRACTICE BENCHMARK ONLY, set to mirror that published standard; this 100-question, 240-minute draw mirrors the trade exam’s length and time and is weighted to PSI’s published outline – General Knowledge and Requirements 10, Warm Air Heating and Air Distribution 25, Ventilation and Exhaust Systems 15, Air Conditioning 10, Piping Systems 10, Equipment and Appliances 20, Testing and Inspection 10. It is a study signal, not a PSI result.
