OP Update: Per usual, great ideas and information!
(1) Regarding installation, fortunately, we know someone who is an electrician, and actually completed a study program years ago, who can do the install. He installed our PowerTek inverter and the install was perfect. We also know someone who designs cages.
(2) My wife discovered the perfect place for the compressor install. Duh! Why didn't I think of it? So obvious. We have a large patio on the second floor where we have sinks and a wash area and our L shaped chicken coop. There happen already to be holes in that wall. It's outside and the chickens could use some warm/hot air during cold nights. Of course, if the nights are cold, probably the AC will not be running! Just so happens that the holes in this wall are in a direct line to the room where the AC will be--a very hot room with no windows. The cabling and gas line would pass through one bedroom, a bathroom, a kitchen, another bedroom, then to outside. With the compressor right within our living area but outside AND with a cage, it's impossible that someone could steal it. Somebody is almost always here . . .
(3) There's a problem and I need your ideas. I understand that since we don't have 220V wiring, that we must opt for 120V. Now I haven't inquired what it would cost to do 220V wiring in a rental (no investment), but I'm thinking that that's out of the question. The problem is that when we look at the Corripio website, which, as you know, is expensive but has the better brands, e.g. Panasonic, ALL require 220V.
120V AC?? Where do we go from here? We still have to go to Radiocentro. Their website is useless: A product catalog that says that you can download that you can't download; NO PRICES!! What???; and almost no specs!! What?? Doesn't even say what the voltages are. Really, all you are doing is looking at pictures with no information. Sorry but "D.R. stupidity" gets my goat. It particularly gets my goat when I realize that the perpetrators of this stupidity are cutting into their own bottom line. So they must not know that they are stupid (to use this instance of the Radiocentro website as an example).
