Nevada HVAC Exam Prep

Current Status

1,450 original practice questions across 19 topics — a 1,250-question HVAC core plus 200 Nevada law, business, and trade questions.
A free 12-question sample exam with a fixed set, so you can gauge the style before you buy.
Two full practice portions — C-21 Trade (85 questions, 180 minutes) and the CMS (60 questions, 120 minutes) — mirroring PSI’s Nevada examinations, drawing fresh questions on every attempt.
Topic drills for focused reps — Nevada licensing law, business and law, refrigeration, heating, airflow, controls, and more.
Our practice exam mirrors PSI’s published Nevada structure — a C-21 Trade portion of 85 questions in 180 minutes and a CMS portion of 60 questions in 120 minutes — and scores each portion against the standard PSI publishes for the real examination: 60 of 85 questions on the Trade portion, and 45 of 60 (75%) on the CMS. PRACTICE BENCHMARK ONLY — your score here is a study signal, not a result on the real exam.
