“I recently passed the Mechanical HVAC/R PE Exam, thanks to Dan Molloy’s Full Access Bundle. The program’s structured approach, with comprehensive practice problems and detailed video solutions, significantly boosted my confidence and deepened my understanding of HVAC and Refrigeration concepts.

Who This Is For

★★★★★

“Dan’s review course for the HVAC/R PE exam was indispensable for me. I had a relatively short time frame to study with two little kids at home and one more on the way. The course was focused and very efficient — I passed on the first try. I also appreciated the personal touch Dan has on his course. He created it, he still runs it, and he makes himself available for questions. It’s not a big corporation where you’re just a number. Dan genuinely cares about his students and their success.”

Frequently Asked Questions

Is all the content available immediately?

Yes. All content is available to you immediately upon enrollment. No drip schedule, no waiting.

Are the practice problems similar to real exam problems?

Yes. Most problems are written to be as hard as exam problems or slightly harder. Every problem has at least one key insight embedded within it — and very often two or three.

Are the solutions based on the CBT format?

All 7 practice modules are solved using the NCEES Mechanical Reference Handbook PDF. The companion practice problems book calls out specific search terms to help you find what you need fast.

I’ve been out of school for a long time. Is this right for me?

Yes. By covering the Fundamentals first, you get the background and context you may have forgotten before working practice problems. It may take a bit more time, but the program is designed to work for everyone.

Are the PDFs downloadable?

Yes. For each of the 7 practice modules and the 2 full practice exams, you get all 5 PDFs: Problem Set, Answer Key, Complete Solutions, Key Formulas, and Key Search Terms — all downloadable from the learning platform.

I’ve already purchased a course included in the bundle — can I upgrade?

Yes. Email Dan and he’ll provide a link with a credit for any course you’ve already purchased.
