Mechanical Engineering Licensure Thermodynamics — HVAC and RefrigerationMisconception Buster
Common misconceptions in HVAC and Refrigeration — and how to avoid them on the Mechanical Engineering Licensure 2026. Professional Regulation Commission (PRC) — Board of Mechanical Engineering loves to write questions that exploit the small mistakes reviewers make, and this page maps out the most frequent traps in the Mechanical Engineering Licensure Thermodynamics subtest.
Exam context
Professional Regulation Commission (PRC) — Board of Mechanical Engineering runs the Mechanical Engineer Licensure Examination on Q3 2026. Its Thermodynamics section sits under a "Core" weighting, and HVAC and Refrigeration is the 8th chapter in the 12-chapter Mechanical Engineering Licensure Thermodynamics rotation. The Mechanical Engineering Licensure passing mark is 70% weighted average, no sub-test below 50%, and the most recent 2026 paper drew about a meaningful share of questions from Thermodynamics.
