Most tend to be around four to five thousand square feet, but generally have
two units in them. I'm wasn't doubting 120 volt units exist, in fact I've
often wondered why they used 240 volts with a relatively small draw. I'll
have to ask an AC guy what the deal is

That surprises me. Mine draws about 5.2 amps, for a 2000 sq. ft.
house. I guess you must be dealing with some pretty big houses,
but I would have thought those would be zoned systems.

Since this is alt.home.repair, isn't as "part of a furnace" where you'd
typically find an air handler? Typically a furnace fan will only draw
about 5 amps at 120 volts anyway, so there's not much motivation to move
to 240V.

Naaah. The air handler will be a 120V load.
