Comment:

Very big ego. If you patronize him and stroke his pride you will do well. Make him look good at the ASHRAE competition and he will help you. If you challenge him he will lose his temper and his ears turn red. Smart but totally vain.

Comment:

His teaching methods are not normal. He would yell at you and tell you that you did it wrong, but on the other hand he would gladly help you correct your issues and understand what you were doing wrong. He would even come in on Saturdays to help his students learn and make sure projects were done on time. Great prof and helps with real world sits

Comment:

This professor is very unprofessional. He responds to every question as if the student is questioning his intelligence. Enjoys talking down to students. Uses the term "creativity" as a grading parameter to take points away for no apparent reason. He also likes to use double negative statements on exams to purposefully confuse students.

Comment:

Textbook narcissist that simply should not be a teacher. Hot-tempered, drops f-bombs, and attacks and belittles students who ask questions. You will have to find a way to let his racial comments, cursing and talking to people like they're mentally handicapped not bother you, just so you can pay attention in lecture. He's very childish, really.

Comment:

Subjective and opinionated. Not a good teacher. If every student in the whole program gets a terrible score on a lab assignment, do you think it may have something to do with the clarity of the instructions? NEVER admits when he is wrong, and he enjoys messing with your future by lowering your GPA. Hopefully you have a different teacher for 362.

Comment:

Very knowledgeable but it seems like he doesn't care too much about students success. He pics favorites in class so its helpful to be part of Ashrae and other student groups. Not very approachable, if you don't understand something and ask a question he will sometimes talk down to you. Watch for his BPM (blinks per minute).

Comment:

Stickler for silly stuff. His heart is in the right place overall but he will waste your time on report format so make sure you follow the format he lays out to a "T". Can be testee and short for not apparant reason. Very knowledgeable but a bore to listen too! OMG he can put you to sleep! :)

Comment:

He is a horrible grader. He hates to give out A's in anything. He will purposefully mark you off big points for little problems in your assignments. If you ask him questions he will get mad and start yelling. On the plus side he seems to know the information.

This class is very demanding but you can learn alot. Also gets reall annoying when professors think thier way is better than anything else you have ever learned and he needs to realize not everyone sees the world the same as him.

Get organized and stay organized! Very good instructor. VERY knowledgable. Assignments pile up quick, but there is always plenty of lead time. Procrastinate and you will BURN! Very demanding instructor, but hard work is acknowledged and rewarded. Opportunities are provided for extra credit.Good luck!!!

Comment:

Don't know what all of this business about easy grading is. He is the most critical grader I have ever seen. Way too much stuff to do in the class. He piled everything on at the end. It is not a good class and he is not a fair teacher.

Great teacher, he really knows what he is talking about. He cares about his students success and their future. He just wants everyone to leave the HVAC program knowing what they need to know.

New teacher. Can tell he has never taught before. Needs to slow down a lot. Pretty easy grader though.
