About this episode
This episode discusses the changes to the 2025 Mechanical PE exam specification and offers guidance for exam preparation.
In this episode of the Mechanical PE Exam Prep Podcast, I break down the upcoming 2025 PE exam specification changes for HVAC and Thermal/Fluid Systems exams. Despite the new four-section structure (loads, systems, equipment, and support), the core engineering concepts remain the same. I explain why engineers shouldn't stress about the changes and provide insights into what to expect, including continued focus on fundamental topics like thermodynamics, heat transfer, and psychrometrics. Learn how to approach your exam preparation strategically and maintain confidence in your study plan. Whether you're taking the exam before or after October 2025, this episode offers valuable guidance for mechanical engineering professionals seeking their PE license.
