Build a study plan around NCEES CBT rules, 80 questions, the 9-hour appointment, October 2025 specifications, thermodynamics, psychrometrics, heat transfer, fluids, loads, equipment, ventilation, controls, refrigeration, and codes.
PE Mechanical: HVAC and Refrigeration combines core mechanical fundamentals with practical HVACR systems, codes, and reference lookup. HiraEdu helps candidates map the October 2025 blueprint, drill psychrometrics and load calculations, and practice full mixed blocks under CBT timing.
Use the current NCEES Mechanical format and October 2025 HVACR specification before planning study time.
NCEES lists PE Mechanical: HVAC and Refrigeration as an 80-question CBT exam in a 9-hour appointment.
The HVAC and Refrigeration PE exam is administered year-round at NCEES-approved Pearson test centers, subject to board approval.
The current HVAC and Refrigeration blueprint is effective beginning October 2025.
Study thermodynamics, psychrometrics, heat transfer, fluids, loads, economics, equipment, systems, ventilation, controls, refrigeration, and codes.
HVACR prep should now use the NCEES specification effective beginning October 2025. Older April 2020 resources can still teach fundamentals, but the active outline and reference list should drive the final plan.
Heating and cooling loads, psychrometric processes, ventilation rates, energy balance, heat transfer, and fluid flow show up across many HVAC problems. Practice reading charts, units, and equipment states quickly.
The exam is not only calculation work. Prepare for system selection, refrigeration cycles, controls, ventilation, economizers, piping, ducts, and code or standard applications using the supplied references.

The NCEES PE Mechanical: HVAC and Refrigeration exam is a computer-based professional engineering licensure exam administered year-round at NCEES-approved Pearson test centers. NCEES lists 80 questions in a 9-hour appointment: 2 minutes for the nondisclosure agreement, 8 minutes for the tutorial, 8 hours of exam time, and a 50-minute scheduled break. Candidates register through MyNCEES and must meet their licensing board's approval rules.
The HVAC and Refrigeration specifications effective beginning October 2025 are closed book with an electronic reference. NCEES provides the PE Mechanical Reference Handbook and applicable standards during the exam. The blueprint covers basic engineering practice, thermodynamics, psychrometrics, heat transfer, fluid mechanics, energy and mass balance, heating and cooling loads, economics, equipment and components, systems and components, ventilation, HVAC controls, refrigeration, and codes and standards.
NCEES lists an 80-question computer-based exam in a 9-hour appointment, including tutorial, nondisclosure agreement, 8 hours of exam time, and a scheduled break.
Yes. NCEES lists the PE Mechanical exams as computer-based and administered year-round at approved Pearson test centers, subject to board approval.
Use the NCEES Mechanical HVAC and Refrigeration specification effective beginning October 2025 for current study planning.
Prioritize psychrometrics, heating and cooling loads, thermodynamics, heat transfer, fluids, equipment, systems, ventilation, controls, refrigeration, and code-based questions.
No. NCEES states the exam is closed book and supplies the PE Mechanical Reference Handbook and listed standards electronically during the exam.
Check your state licensing board's PE requirements before registering through MyNCEES.
Build study blocks for thermodynamics, psychrometrics, heat transfer, fluids, energy balance, loads, economics, equipment, systems, ventilation, controls, refrigeration, and codes.
Practice using the PE Mechanical Reference Handbook and listed HVAC standards for calculations, code checks, tables, charts, and equipment data.
Combine load calculations, psychrometric processes, refrigeration cycle work, equipment selection, duct and pipe problems, controls, and code questions under exam pacing.
Use the guide to self-serve, or talk to a coordinator if you need help mapping timelines, official requirements, or troubleshooting day-of logistics.
