Thanks for the info... I thought it would have been a somewhat easy switch. Now that I read more, it looks like the task could cost more than double once you start buying everything else. I thought these units could be mounting to the outside wall of the house? Is that only certain models? I have a separate breaker box outside for a second AC with available spots for the 3 breakers. I was thinking of mounting it near that so it wouldn't take much wire. Am I thinking wrong?
I was wanting to get away from the gas and go total electric. My gas bill runs about $25 a month and it's just the hot water heater on "normal" setting. Seems like it isn't very efficient.
