The P-Tec is an Amana unit. My HVAC guy sized the unit and wanted $1600 for it. My client found the same exact thing ****** for a little over $700 delivered. This is a self contained, 220v unit that is mounted through the wall. Other than being on a dedicated circuit, I can't give you specifics on the electrical, the electrician took care of that.

Installation was pretty straight forward, just use care in your layout so that you don't over cut the hole and have huge, jagged, ugly gaps around it. Once you've got it cut and headed out, you just slip the wall sleeve into place and screw it in, then the unit slides inside the sleeve. It comes with well written instructions, so it's all pretty easy.
