Good quiz although was mainly review for me (Arrghrr two I missed I knew better!)
As your time & interest permits, I could use gas furnace and air-source HP troubleshooting type quiz questions to aid in my experience development.
As you probably aware, grayfurnaceman.com seems to be big on YTubes on gas furnace problems then others I’ve seen.
Please know that, besides HVAC School being recently added main source of my learning & review, I regularly view acservicetech.com YTubes.
I appreciate both yours and his teaching and knowledge imparting styles since are crisp, concise, and clear – also respectful and safety and do-it-the-right-way oriented.

However, I like really appreciate HVAC School for the not using YTube videos since the web site resources, quizzes, emailed & posted articles with diagrams allow one to print & keep in my 3-ring reference binder. Also the listening podcasts use little cell phone data bytes. I don’t always have time to view videos or see my cell phone data GB limit exceeded. Enjoy when you and Nathan cutting up although sometimes a little zany and hard for me to keep up, comic relief is appreciated.

Thanks for your time and dedication to improving the industry. Your perspectives, ways of approach, and knowledge make professional techs proud to be in the HVAC-R industry.

P.S. I realize web site title is HVAC not HVAC-R but, if I may add to my wish list, would also be interested in commercial refrigeration troubleshooting. I had a class Spring 2016 semester on Comml Refrig but limited in school lab what can practice.

That’s a very interesting high efficiency furnace quiz. Most guys with no schooling couldn’t pass that quiz.

I enjoyed taking this quiz! Helped out but I was also wondering if these get updated because apparently question 4 all answers were wrong and on the evacuation quiz one of the questions didn’t have an image
