This class does a great job of assuming the student has no knowledge of heat pumps and imparting some of the basic concepts needed to understand heat pumps.

Bill Nowak

Worth the time to break down the fundamentals of thermo-dynamics and heat pump technology. Great starting point.

Daniel O'Coin

I encourage college students to give a look at the HVAC&R field, it's a very open market in US and it is really interesting.
