I quick overview of cold climate heat pumps and the selection process, with examples. Can't ask for much more in a 30 minute course!

very informational for someone who doesn't understand the ratings of equipment and how it effects the heating and cooling modes.

I found this to be a great course that I could work at my own pace, and work around the 1,000 interruptions that take over my every day. Being able to pause, and rewind a minute or two to make sure I picked up where I left off were great features.

Understanding COP and how it is used isnt hard to work with if you understand how ts applied. I would have to wonder how many students dont know COP and how to apply to a job.

This is a pointed resource as an intro to mini-split systems. It just wets the appetite and makes you salivate. I think it is a viable option to supplement an existing system or a replacement option in some cases.

The views given by instructor are neutral and not favoring any particular brands and that is beauty of this course.
