Yeapers, it's a 240v system.
Speaking of extra charges, I just saw a good price for an indoor unit at
KHS2472 - Sanyo KHS2472 - 24,200 BTU Ductless Mini-Split Wall-Mounted Heat Pump & Air Conditioner (Indoor Unit)
If I could repair my leaky outdoor unit, & invest about $500,
then I would have another compete system!
