Basement heat/ac units

I'd think the refrigerant tubing on a mini-split would be at the most risk in a bus install. The multi zone units are (petty much) all 240 Volts. The expesnsive ones, with Japanese names on 'em, are inverter power controlled. They take the line voltage and make variable DC voltage to run the compressor. The advantage to that for us is that the compressor starts on lower amps, so our 30 amp power supply, or wimpy generator can start them easier than regular air conditioners. The disadvantage is that with all the fancy electronics in them you're at risk of an expensive repair bill from voltage spikes, etc., so I've read.

Im not overly worried about the line set set. I think you can encase them in a line set cover simular to a rub rail on the outside to not really worry about them as the line set wont be very long. Seems odd for them to not have a 115v model but Im sure stranger things have happened. The one I am looking at are made by Goodman as I have a inside track with them.

I can see the dirty power being an issue and I would imagine those dont come cheap. With the reading you have done has anyone put them in a bus?

Yes sseveral folks on busnuts have installed mini splits on coaches

Is there that much of an advantage to separating the compressor and condensor vs just mounting the units underneath and ducting the output into the bus through the floor?

No duct work with the split units, easier to install.
