In this section you will find my various manuals, writings, and presentations having to do with HVAC/R. Having spent 14 years teaching and guiding an HVAC/R department I have a lot of material hidden away. You are welcome to use anything from this section in your own classes, or for your own education. If you do use please give credit where credit is due and link to this website. I do not make any profit off the the advertising here, but it does help pay for internet use.
Education does NOT exempt you from copyright laws, the material is shared with the above condition. No, changing the powerpoint background does not make it yours.
